Description

FIELD OF THE INVENTION

[0001] The present invention relates to the technical field of textile finishing compositions, in particular textile softening compositions, water-repellent finishing compositions and textile finishing compositions for improving the wicking properties, and processes for textile finishing.BACKGROUND OF THE INVENTION

[0002] Nowadays, the textile industry uses many industrial finishing treatments. Thus, textiles are frequently subjected to a finishing process, which confers certain characteristics on the textile thus finished. The finishing process can be carried out mechanically (e.g. emerizing, compressive shrinkage, shearing) or chemically and provides to the product its final appearance and properties.

[0003] Chemical finishing consists of the modification of textile fibers through chemical action. Chemical finishing is typically carried out by padding, during which the textile is fully immersed in a textile finishing composition and subsequently subjected to repeated cycles of drying (typically by exposure to IR), fixation (typically by using a high temperature fixation frame) and condensation. The padding process leads to considerable use of resources, such as finishing compositions, water and energy.

[0004] Depending on the used textile finishing composition, the chemical finishing treatment can impart to the textile a wide variety of properties, such as softness, water-repellence, improved wicking properties, UV-blocking properties, and flame retardancy properties.

[0005] A textile softening composition is a textile finishing composition, which makes the textile soft, fluffy and anti-static, thereby providing it with a soft hand. A textile softening composition contains a softener or a softening agent, which reduces the friction coefficient between fibers leading to the surface softness and lubricating effect on fibers. Currently silicones (polyxiloxanes), including epoxy or / and amino-modified polysiloxanes, polyether-modified polysiloxanes, which contain polyether active groups grafted on the side chains of polysiloxane chains, and linear multiblock polysiloxane copolymers, are widely used as softeners or softening agents in a textile softening composition to impart softness to and improve the wear feeling of the treated textile. Silicone softening agents are synthetic compounds, the synthesis of which generally requires a lot of energy. Moreover, the production of textile softening composition using silicone softeners has a high carbon footprint since a lot of energy is required for obtaining the desired emulsion. Furthermore, silicone softening agents are not biodegradable and accumulate in the environment.

[0006] A water-repellent finishing composition provides the treated textile with water-repellent properties. A water-repellent finishing composition typically contains a fluorinated water-repellent agent, such as a per- or polyfluoroalkyl substance (PFAS). Fluorinated compounds, in particular PFAS, are known to accumulate in the environment, drinking water and food, and to be harmful to the environment and the human body.

[0007] The consumers' expectations in terms of textiles they use and the manufacturing processes of said textiles have drastically increased lately. Besides suiting their taste in terms of appearance and properties, the textiles must be health- and environment-friendly and produced by environmentally friendly manufacturing processes.

[0008] Given the drawbacks of the currently available textile finishing compositions and processes, particularly in terms of non-biodegradability and toxicity of the finishing agents, and the water and energy consumption, there is a need for a textile finishing composition containing health- and environmentally-friendly ingredients (i.e. biodegradable ingredients that are not harmful for the humans and the environment) that is applicable to the textile by processes other than padding. The composition should also comply with the specific requirements of the textile finishing compositions, such as washing durability (i.e. the maintenance of the characteristics imparted to the textile by the finishing composition after repeated cycles of washing), high affinity for the textile fibers, stability during storage, chemical treatment, and following fixation to the textile, and non-modification of the textile color.SUMMARY OF THE INVENTION

[0009] Accordingly, it is an object of the present invention to provide a silicone-free and fluorine-free textile finishing composition comprising, preferably consisting of:

[0010] i) from about 10.0 wt-% to about 30.0 wt-% 1,2,3-propanetriol, preferably of vegetal origin;

[0011] ii) from about 0.05 wt-% to about 10.0 wt-% of a surfactant;

[0012] iii) from about 1.0 wt-% to about 10 wt-% of a finishing agent selected from an oil of vegetal origin, a wax of vegetal origin, a beeswax, and an esterquat, with the proviso that if the finishing agent is a wax of vegetal origin or a beeswax, the composition may further contain a wax extender, wherein preferably said wax extender is a blocked isocyanate;

[0013] iv) optionally a thickening agent and / or a biocide and / or a pH adjusting agent; and

[0014] v) water up to 100 wt-%; wherein the wt-% are based on the total weight of the composition.

[0015] Preferably, the composition claimed and described herein is an ink jet printable composition, preferably a piezoelectric drop-on-demand ink jet printable composition.

[0016] Another aspect according to the present invention is directed to a process for treatment of a textile in a textile finishing process with the inventive composition, preferably comprising the following steps:

[0017] a) applying one or more of the inventive compositions on a textile, preferably on a side of said textile or on one or more regions of a side of said textile;

[0018] b) drying the textile to obtain a dried textile, preferably by exposing the textile to an air having a temperature from about 120° C. to about 140° C.; and

[0019] c) calendering the dried textile for at least 10 seconds at a temperature from about 140° C. to about 220° C., preferably from about 180° C. to about 220° C. During the calendering step, the pressure is preferably from 2 to 4 bars.

[0020] Also claimed and described herein is a finished textile obtained by the process according to the present invention and a garment comprising said finished textile obtained.DETAILED DESCRIPTION OF THE INVENTION

[0021] Thus, it is an object according to the present invention to address the need for a textile finishing composition containing health- and environmentally-friendly ingredients that is applicable to the textile by processes other than padding, and which complies with the specific requirements of textile finishing compositions, such as washing durability, high affinity for the textile fibers, stability during storage, chemical treatment, and following fixation to the textile, and non-modification of the textile color (the composition per se is colorless i.e. no color is detectable by the naked eye, and following fixation does not modify the color of the treated textile).

[0022] The present invention will be described in more detail below.

[0023] Where the present description refers to “preferred” embodiments / features, combinations of these “preferred” embodiments / features are also deemed to be disclosed as long as the specific combination of the “preferred” embodiments / features is technically meaningful.

[0024] Unless otherwise stated, the following definitions shall apply in this specification:

[0025] As used herein, the term “a”, “an”, “the” and similar terms used in the context of the present invention (especially in the context of the claims) are to be construed to cover both the singular and plural unless otherwise indicated herein or clearly contradicted by the context.

[0026] As used herein, the term “and / or” means that either all or only one of the elements of said group may be present. For example, “A and / or B” means “only A, or only B, or both A and B”. In the case of “only A”, the term also covers the possibility that B is absent, i.e. “only A, but not B”.

[0027] As used herein, the terms “including”, “containing” and “comprising” are used herein in their open-ended, non-limiting sense. It is understood that the various embodiments, preferences and ranges may be combined at will. Thus, for instance a solution comprising a compound A may include other compounds besides A.

[0028] However, the term “comprising” also covers, as a particular embodiment thereof, the more restrictive meanings of “consisting essentially of” and “consisting of, so that for instance “a solution comprising A, B and optionally C” may also (essentially) consist of A and B, or (essentially) consist of A, B and C. As used herein, the transitional phrase “consisting essentially of” (and grammatical variants) is to be interpreted as encompassing the recited materials or steps and those that do not materially affect the basic and novel characteristic(s) of the claimed invention. Thus, the term “consisting essentially of” should not be interpreted as equivalent of “comprising”.

[0029] As used herein, the term “about” means that the amount or value in question may be the specific value designated or some other value in its neighborhood. Generally, the term “about” denoting a certain value is intended to denote a range within ±5% of the value. As one example, the phrase “about 100” denotes a range of 100±5, i.e. the range from 95 to 105. Preferably, the range denoted by the term “about” denotes a range within ±3% of the value, more preferably ±1%. Generally, when the term “about” is used, it can be expected that similar results or effects according to the invention can be obtained within a range of ±5% of the indicated value.

[0030] Surprisingly, it has been found that a silicone-free and fluorine-free textile finishing composition comprising, preferably consisting of:

[0031] i) from about 10.0 wt-% to about 30.0 wt-% 1,2,3-propanetriol, preferably of vegetal origin;

[0032] ii) from about 0.05 wt-% to about 10.0 wt-% of a surfactant, preferably a biodegradable surfactant;

[0033] iii) from about 1.0 wt-% to about 10 wt-% of a finishing agent selected from an oil of vegetal origin, a wax of vegetal origin, a beeswax, and an esterquat, with the proviso that if the finishing agent is a wax of vegetal origin or a beeswax, the composition may further contain a wax extender, wherein preferably said wax extender is a blocked isocyanate; and

[0034] iv) optionally a thickening agent and / or a biocide and / or a pH adjusting agent; and

[0035] v) water up to 100 wt-%; with the wt-% being based on the total weight of the composition may be used as a textile finishing composition for imparting to the textile softness, water-repellence and / or improved wicking properties. Advantageously, the majority of the ingredients contained by the composition are natural and biodegradable. Further, the composition does not contain silicones and fluorinated compounds, which are known to be non-biodegradable and even toxic. The textile finishing compositions claimed and described herein are colorless i.e. they do not contain pigments and / or dyes having a color detectable by the naked eye. In other words, the textile finishing compositions claimed and described herein are pigment-free and dye-free.

[0036] As well known to the skilled person, finishing agents are substances that change a property, other than a color, of a textile. The properties imparted to the textile depend on the finishing agent contained by the finishing composition. In the present invention, the finishing agent is a fatty acid ester containing finishing agent (i.e. a finishing agent containing one or more fatty acid esters) and is selected from an oil of vegetal origin, a wax of vegetal origin, a beeswax, and an esterquat.

[0037] The term “silicone-free composition” refers to a composition that does not contain a silicone / polysiloxane. As used herein, the term “silicone” and “polyxiloxanes” encompasses all polymers containing a polysiloxane moiety including, but not limited to, silicones / polysiloxanes oils, modified polysiloxanes, such as epoxy or / and amino-modified polysiloxanes, and polyether-modified polysiloxanes, and linear multiblock polysiloxane copolymers.

[0038] The term “fluorine-free composition” refers to a composition that does not contain a fluorinated compound, such as a per- or polyfluoroalkyl substance (PFAS).

[0039] The inventive composition may contain up to 1.0 wt-% of a thickening agent. As well known to the skilled person, a thickening agent or a thickener is a substance that increases the viscosity of a liquid without substantially changing its other properties. A person skilled in the art is in a position to adjust the amount of the thickening agent so as to obtain the viscosity required for the textile finishing composition. Preferably, the thickening agent is a polysaccharide (e.g. starches, vegetable gums) of vegetal origin. Examples of suitable thickening agents include, but are not limited to, carob (also known as locust bean gum or carob gum containing at least 75% galactomannan), such as commercially available Carob EXC 25 from HEIQ—Switzerland, guar gum, carrageenan, and alginin. Advantageously, the thickening agent is commercially available and easily dispersible in water upon mixing.

[0040] Further, the inventive composition may contain up to 0.5 wt-% of a biocide. The biocide prevents biodeterioration of the textile, assists in preventing spread of infectious diseases without requiring the need for frequent sterilization and ensures the stability of the textile finishing composition for at least 12 months. Any conventionally used biocide in textile industry is suitable to be used in the textile finishing composition according to the present invention. Such biocides include, but are not limited to, 1,2-benzisothiazolin-3-one (commercially available at Zeneca Specialties as a solution sold under the commercial name Proxel GXL), organo-copper compounds, organo-tin compounds, chlorinated phenols, silver-based microbial agents and metal-based inorganic compounds, such as zinc oxide, zinc salts and cupric salts.

[0041] Preferably, the textile finishing composition has a pH value of between 5 and 9. The pH value depends on the intended use (e.g. softening, water-repellency) and the stability conditions of the finishing composition, as well as on the performance and effect obtained in the fabric. If required, the textile finishing composition may further contain up to 0.5 wt-% a pH adjusting agent, preferably of vegetal origin. Preferably, the pH adjusting agent is selected from acetic acid, citric acid, ascorbic acid, malic acid, etc. Preferably, citric acid is used for adjusting the pH value of the composition in the pH value range from 5 to 7, while acetic acid is used for adjusting the pH value of the composition in the pH value range from 7 to 9.

[0042] The textile finishing composition according to the present invention may be applied to the textile by coating, spraying or ink jet printing.

[0043] In a preferred embodiment, the textile finishing composition claimed herein is an ink jet printable composition, preferably a piezoelectric drop-on-demand ink jet printable composition. The piezoelectric drop-on-demand ink jet printable compositions have a viscosity from 2 cP to 10 cP, more preferably from 6 to 7 cP, at 25° C. and a shear rate 200-400 s−1 as measured with a viscometer BROOKFLIED DVN, flat cone, 50 RPM. To avoid clogging of the printhead, the particle size of the solid ingredients potentially present in the textile finishing compositions is preferably lower than 1 μm. As used herein, particle size lower than 1 μm is intended to refer to D99 diameter lower than 1 μm. The use of the inkjet printing, preferably piezoelectric drop-on-demand inkjet printing, enables selective application of a well-defined amount of the finishing composition on a side of the textile, or on one or more regions of a side of the textile. Owing to the accurate dosing of the textile finishing composition achieved by inkjet printing, the volume of applied textile finishing composition is significantly lower (4 to 6 times lower) than the one required for finishing by padding, and a constant deposit of the finishing composition is applied on the entire surface to be treated, leading to a high performance that is not reachable by padding processes. Further, the volume of wastewater produced in the finishing process is reduced by a factor 4 to 6 compared to the padding finishing process. Also, the consumed energy is significantly reduced with the present finishing process. Advantageously, the compositions claimed and described herein are ready-to-use i.e. they do not require a preparation on-site and before each finishing process as it is the case for finishing processes including a padding step. The textile finishing compositions claimed and described herein are compatible with commercially available industrial textile printers (e.g. Panthera D8 or Panthera S4 from Swiss Performance Chemicals; LaRIO from MS Printing Solutions), which require significantly less space and human intervention than the currently available industrial textile padder.

[0044] A preferred embodiment according to the present invention is directed to a textile finishing composition as claimed and described herein wherein

[0045] iii-1) the finishing agent is an oil of a vegetal origin and the composition contains from about 1.0 wt-% to about 6.0 wt-% of said oil of a vegetal origin. Such textile finishing composition is particularly useful for imparting to the textile improved softness and / or wicking properties. The term “oil of vegetal origin” encompasses any oil or triglyceride extracted from plants, e.g. from fruits or seeds. Examples of suitable oils, include but are not limited to, almond oil, babassu oil, borage oil, canola oil, coconut oil, corn oil (maize oil), cottonseed oil, flaxseed oil, grape seed oil, hazelnut oil, oat oil, olive oil, palm oil, palm kernel oil, peanut oil, rapeseed oil, safflower oil, sesame oil, linseed oil, soybean oil, tucum oil, sunflower oil, walnut oil, apricot oil, sweet almond oil, avocado oil, baobab oil, blueberry seed oil, calendula oil, camellia oil, cherry kernel oil, cranberry seed oil, hemp oil, jojoba oil, kukur nut oil, macadamia nut oil, manketti oil, melon seed oil, moringe oil, peach kernel oil, pistachio oil, raspberry seed oil, rice bran oil, rosehip oil, soya oil, wheat germ oil, yangu oil, algae oil; their hydrogenated derivatives, and mixtures thereof. In a preferred embodiment, the oil of vegetal origin is selected from rapeseed oil, linseed oil, algae oil, their hydrogenated derivatives, and mixtures thereof.

[0046] An alternative preferred embodiment according to the present invention relates to a textile finishing composition as claimed and described herein wherein the finishing agent is a wax of a vegetal origin or a beeswax and the composition contains from about 6.5 wt-% to about 10 wt-% of said wax of a vegetal origin or said beeswax. Such finishing composition is particularly useful for imparting water repellence to the textile. Advantageously, the composition claimed and described herein is also free of paraffin wax, a non-biodegradable ingredient widely used in water-repellent textile finishing compositions. Such composition may further contain a wax extender to improve the performance of the wax by increasing the water-repellency properties provided by the wax to the textile and / or the wash durability. Thus, a preferred embodiment according to the present invention relates to a textile finishing composition as claimed and described herein wherein

[0047] iii-2) the finishing agent is a wax of a vegetal origin or a beeswax and the composition contains from about 6.5 wt-% to about 10 wt-% of said wax of a vegetal origin or said beeswax, and from about 1.5 wt-% from about 4.5 wt-% of a wax extender.

[0048] The term “wax of vegetal origin” encompasses all waxes originating from plants. Examples of suitable vegetable waxes, include, but are not limited to: carnauba wax, soy wax, jojoba wax, candelilla wax, rice-bran wax, sugar cane wax, and mixtures / blends thereof. As well known in the art, carnauba wax (also called palm wax) is a common plant wax type harvested from the leaves of the plant by drying the leaves and beating them to loosen the wax. The Carnauba wax contains aliphatic esters (approx. 40 wt-%), diesters of 4-hydroxycinnamic acid (approx. 21.0 wt-%), CO-hydroxycarboxylic acids (approx. 13.0 wt-%), and fatty alcohols (approx. 12 wt %). The compounds are predominantly derived from acids and alcohols in the C26-C30 range. In one embodiment, the wax of vegetal origin is Carnauba wax and the finishing composition does not contain a wax extender.

[0049] In a preferred embodiment the wax of vegetal origin is candelilla wax. Candelilla wax comes from the small leaves of Candelilla shrubs native to northern Mexico and the southwestern U.S. It is harvested by immersing the whole plant in acidified boiling water. The wax then floats to the surface of the boiling water.

[0050] As well known in the art, a wax extender is a substance used in combination with a wax to improve the performance of said wax e.g. by increasing the water-repellency of the treated textile or the wash durability. Preferably, the wax extender is selected from urethanes, blocked isocyanates, and mixtures thereof. The wax extender is preferably a mixture of two or more urethanes, or a mixture of two or more blocked isocyanates. Suitable urethanes have been described in WO2015191326A1 and are prepared by reacting

[0066] For isocyanate-reactive compounds of formula (IIa), (IIb), or (IIc), the —(CH2CH2O)—represents oxyethylene groups (EO) and —(CH(CH3)CH2O)— represents oxypropylene groups (PO). These compounds can contain only EO groups, only PO groups, or mixtures thereof. These compounds can also be present as a tri-block copolymer designated PEG-PPG-PEG (polyethylene glycol-polypropylene glycol-polyethylene glycol), for example.

The pentaerythriol esters also may contain compounds with mixtures of different chain lengths for R5, or mixtures of compounds where R6 comprises at least one unsaturated bond with compounds where R6 is fully saturated.

[0080] Compounds of formulas (IIa), (IIb), and (IIc) can all be bio-based derived. By “bio-based derived”, it is meant that at least 10% of the material can be produced from non-crude oil sources, such as plants, other vegetation, and tallow. In one embodiment, the compounds of formulas (IIa), (IIb), and (IIc) are from about 10% to 100% bio-based. In one embodiment, the compounds of formulas (IIa), (IIb), and (IIc) are from about 35% to 100% bio-based. In one embodiment, the compounds of formulas (IIa), (IIb), and (IIc) are from about 50% to 100% bio-based. In one embodiment, the compounds of formulas (IIa), (IIb), and (IIc) are from about 75% to 100% bio-based. In one embodiment, the compounds of formulas (IIa), (IIb), and (IIc) are 100% bio-based. At least one R5, R8, R9, R10 of each of formulas (IIa), (IIb), and (IIc) is —H to allow reactivity with isocyanate groups.

[0081] To manufacture the urethane wax extender, a compound of formula (IIa), (IIb), or (IIc), or mixtures thereof, is reacted with an isocyanate group-containing isocyanate, diisocyanate, polyisocyanate, or mixture thereof. The term “polyisocyanate” is defined as di- and higher-functional isocyanates, and the term includes oligomers. Any monoisocyanate or polyisocyanate having predominately two or more isocyanate groups, or any isocyanate precursor of a polyisocyanate having predominately two or more isocyanate groups, is suitable for preparing the urethane extender. For example, hexamethylene diisocyanate homopolymers are suitable for use herein and are commercially available. It is recognized that minor amounts of diisocyanates can remain in products having multiple isocyanate groups.

[0082] Also suitable for use as the polyisocyanate reactant are hydrocarbon diisocyanate-derived isocyanurate trimers. Preferred is DESMODUR N-100 (a hexamethylene diisocyanate-based vailable from Bayer Corporation, Pittsburgh, PA). Other suitable triisocyanates are those obtained by reacting three moles of toluene diisocyanate. The isocyanurate trimer of toluene diisocyanate and that of 3-isocyanatomethyl-3,4,4-trimethylcyclohexyl isocyanate are other examples of triisocyanates useful for the purposes of this invention, as is methane-tris-(phenylisocyanate). Precursors of polyisocyanate, such as diisocyanate, are also suitable for use in the present invention as substrates for the polyisocyanates. DESMODUR N-3300, DESMODUR N-3600, DESMODUR Z-4470, DESMODUR H, DESMODUR N3790, and DESMODUR XP 2410, from Bayer Corporation, Pittsburgh, PA, and bis-(4-isocyanatocylohexyl)methane are also suitable.

[0083] Preferred polyisocyanate reactants are the aliphatic and aromatic polyisocyanates containing biuret structures, or polydimethyl siloxane containing isocyanates. Such polyisocyanates can also contain both aliphatic and aromatic substituents. Particularly preferred as the (poly)isocyanate reactant are commercially available hexamethylene diisocyanate homopolymers, for instance as DESMODUR N-100, DESMODUR N-75 and DESMODUR N-3200 from Bayer Corporation, Pittsburgh, PA; 3-isocyanatomethyl-3,4,4-trimethylcyclohexyl isocyanate available, for instance as DESMODUR I (Bayer Corporation); bis-(4-isocyanatocylohexyl)methane available, for instance as DESMODUR W (Bayer Corporation) and diisocyanate trimers of formulas (IIIa), (IIIb), (IIIc), (IIId), and (IIIe):The diisocyanate trimers (IIIa-IIIe) are available, for instance as DESMODUR Z4470, DESMODUR IL, DESMODUR N-3300, and DESMODUR XP2410, and DESMODUR N100, respectively, from Bayer Corporation.In preferred embodiments, the wax extender is a blocked isocyanate, preferably a blocked isocyanate selected from the group consisting of blocked-isocyanates having a molecular weight of below 2000 g / mol. Blocked isocyanates are well known in the field and are commercial items. Suitable blocked isocyanates are based on isocyanate chemistry, where a poly-functional isocyanate has been reacted with a blocking agent described below to produce a product which is inert at room temperature with no isocyanate functionality. The isocyanate functionality can be restored by heating the blocked isocyanate above its activation temperature, when the blocking action is reversed and the isocyanate group becomes available to react with suitable functional groups. During the textile finishing process, the surface temperature of the textile can be increased to cause this activation and the subsequent cross-linking reactions occurring within the polymer resulting following activation, and between the polymer resulting following activation and fiber surfaces within the textile.

[0085] Blocking agents for isocyanates are known per se and include organic compounds with at least one active hydrogen; they may be selected by the skilled person. Advantageously, the blocking agent is selected from compounds such as alcohols, lactams, phenols, oximes and pyrazoles. The blocking agent may also be chosen from a plant based phenolic compound to provide a system with an increased biocarbon content and a higher degree of sustainability. Blocking agents of this type include Cardanol (3-pentadeca-dienyl-phenol) which may be derived from cashew nutshell liquid.

[0086] Advantageously, the isocyanate is selected from the class of aliphatic isocyanates including hexamethylene diisocyanate, isophorone diisocyanate, trimethylhexamethylene diisocyanate, hydrogenated diphenyl methane diisocyanate. Thus, in a preferred embodiment the wax extender is an aliphatic blocked isocyanate, preferably selected from the group consisting of aliphatic blocked-isocyanates having a molecular weight of below 2000 g / mol.

[0087] The blocked isocyanate described herein is preferably obtained by reacting an isocyanate, preferably an isocyanate selected from the group of aliphatic isocyanates, having a molecular weight below 2000 g / mol with an agent selected from alcohols, lactams, phenols, oximes and pyrazoles; preferably 3,5 dimethylpyrazole.

[0088] Commercial examples of suitable blocked isocyanates include: Blocked isocyanate TTL (available from Beyond Surface Technologies AG), blocked isocyanate EXT-SYN 1.0 (for synthetic fibers) and EXT-CEL 1.0 (for cellulosic fibers) (available from Beyond Surface Technologies AG), Baygard EDW and Baygard FBI (available from Tanatex). The blocked isocyantes are usually insoluble in water and are usually supplied as dispersions in water.

[0089] A further alternative preferred embodiment is directed to a textile finishing composition as claimed and described wherein

[0090] iii-3) the finishing agent is an esterquat and the composition contains from about 4.0 wt-% to about 7.5 wt-% of said esterquat. This textile finishing composition is particularly suitable for providing long-term softness and improved wicking properties (i.e. the softness / wicking property is maintained after multiple washings) to the treated textiles. As known to the skilled person, an “esterquat” or “ester quat” is a quaternary ammonium salt of an alkanol- and / or alkyl-amine esterified with an average of two fatty acid moieties per molecule. In the composition claimed and described herein, the esterquat is preferably a compound of formula (I)wherein

[0092] R—C(O) represents the residue of a fatty acid having from about 12 to about 24, preferably from about 14 to about 22, more preferably from about 16 to 20 carbon atoms;

[0093] R1 is an alkyl group of 1 to 4 carbon atoms,

[0095] -L- is an alkylene of 1 to 4 carbon atoms, and

[0096] X− is a salt forming anion.

[0097] The salt forming cation X− renders the esterquat soluble or dispersible in water, and is preferably selected from a halide, e.g. a chloride, a bromide or an iodide; a sulfate, a methosulfate, a nitrite, a nitrate, a phosphate, and a carboxylate, e.g. an acetate, an adipate, a proprionate. Examples of suitable commercially available esterquats, include, but are not limited to bis-(oleic isopropyl ester) dimethyl ammonium methosulfate (supplier: Evonik; commercial name: REWOQUAT® CR 3099).

The used 1,2,3-propanetriol is preferably of vegetal origin e.g. derived from from soybean, coconut, palm or corn oils. The 1,2,3-propanetriol in the specified amount renders the compositions stable during the shell-life (at least 12 months) and ejectable by inkjet printing, particularly piezoelectric drop-on-demand inkjet printing.

[0099] Further, the inventive textile finishing composition contains from about 0.05 wt-% to about 10.0 wt-% of a surfactant. The term “surfactant” is known in the field. It particularly includes compounds that reduce surface tension and / or improve dispersion properties. A person skilled in the art is in a position to identify surfactants suitable for compositions printable by (piezoelectric drop-on-demand) ink jet. The term includes cationic, anionic, non-ionic and zwitterionic surfactants. Preferably, the surfactant is biodegradable and / or obtained from renewable raw materials. Examples of suitable commercially available surfactants include, but are not limited to, rhamnolipids (e.g. biosurfactant REWOFERM® RL 100 commercially available from Evonik), sophorolipids (e.g. biosurfactant REWOFERM® SL ONE commercially available from Evonik), sorbitane monooleate (commercially available under the commercial name Span® 80 from Sigma Aldrich), polyethylene glycol sorbitan monooleate (e.g. Tween® 80 commercially available from Sigma Aldrich), sodium dioctylsulfosuccinate, ethoxylated 2,4,7,9-tetramethyl-5-decyne-4,7-diol, and mixtures thereof (e.g. Surfinol® PSA 336 commercially available from Evonik which is a blend of sodium dioctylsulfosuccinate and ethoxylated 2,4,7,9-tetramethyl-5-decyne-4,7-diol).

The viscosity can be measured with a viscometer BROOKFIELD DVN, flat cone, 50 RPM.

[0149] A second aspect according to the present invention is directed to a kit for finishing a textile comprising:

[0150] a first silicone-free and fluorine free inkjet, preferably piezoelectric drop-on-demand inkjet, printable composition comprising, preferably consisting of from about 20.0 wt-% to about 30.0 wt-% 1,2,3-propanetriol, preferably of vegetal origin; from about 0.2 wt-% to about 1.0 wt-% of a surfactant as described herein; from about 6.5 wt-% to about 10 wt-% of a wax of vegetal origin as described herein or a beeswax; optionally a thickening agent as described herein and / or a biocide as described herein and / or a pH adjusting agent as described herein; and water up to 100 wt-%; and

[0151] a second silicone-free and fluorine free inkjet, preferably piezoelectric drop-on-demand inkjet, printable composition comprising, preferably consisting of: from about 20.0 wt-% to about 30.0 wt-% 1,2,3-propanetriol, preferably of vegetal origin; from about 0.2 wt-% to about 1.0 wt-% of a surfactant as described herein; from about 1.5 wt-% from about 4.5 wt-% of a wax extender as described herein; optionally a thickening agent as described herein and / or a biocide as described herein and / or a pH adjusting agent as described herein; and water up to 100 wt-%. The first silicone-free and fluorine free inkjet, preferably piezoelectric drop-on-demand inkjet, printable composition and the second silicone-free and fluorine free inkjet, preferably piezoelectric drop-on-demand inkjet, printable composition are printed simultaneously on a side of a textile, or on one or more regions of a side of a textile and mix on the surface of the textile. Following drying of the textile and calendering as described herein, the finished textile exhibits improved water-repellency and wash durability.

[0152] A third aspect according to the present invention is directed to a process for treatment of a textile in a textile finishing process with the composition claimed and described, preferably comprising the following steps:

[0153] a) applying one or more of the compositions described herein on a textile;

[0154] b) drying the textile to obtain a dried textile, preferably by exposing the textile to an air having a temperature from about 120° C. to about 140° C.; and

[0155] c) calendering the dried textile for at least 10 seconds at a temperature from about 140° C. to about 220° C., preferably from about 180° C. to about 220° C., and preferably at a pressure from 2 to 4 bars.

[0156] Preferably, the finishing process claimed and described herein does not contain a padding step. Hence, at step a) the one or more finishing compositions are preferably applied to the textile by coating, spraying or ink jet printing.

[0157] In a preferred embodiment, the one or more compositions are applied by inkjet printing, preferably piezoelectric drop-on-demand inkjet printing. The use of inkjet printing enables selective application of a well-defined amount of the one or more finishing compositions on a side of the textile, or on one or more regions of a side of the textile. Thus, the inventive finishing process allows for finishing of a single side of the textile or of certain regions of a side of a textile. This selective finishing cannot be achieved by padding. As well known in the art, the term “side” refers to the front side or the back side of a textile. Moreover, the present finishing process enables the simultaneous application of several finishing compositions. Owing to the accurate dosing of the textile finishing compositions achieved by inkjet printing, the volume of applied textile finishing composition is significantly lower than the one required for finishing by padding and a constant volume of finishing composition is applied on the entire surface to be treated. Further, the volume of wastewater produced in the finishing process and the consumed energy are significantly reduced compared to the padding finishing process.

[0158] In a preferred embodiment, the one or more compositions are applied by piezoelectric drop-on-demand inkjet printing. The low drop volume (5 pL, 7 μL, 12 pL, 18 pL) ejected by and the precise deposit achieved with a piezoelectric drop-on-demand inkjet printhead, results in a uniform (constant wet deposit on the entire treated surface of the textile) finishing of the textile.

[0159] At step b) of the inventive finishing process, the textile is subjected to drying to evaporate the water contained in the finishing compositions and provide a dried textile. This step is preferably achieved by exposure of the coated / sprayed / inkjet printed textile to an air having a temperature from about 120° C. to about 140° C. The exposure time depends on the surface density (g / m2) of the deposited finishing composition and the used temperature and is preferably lower than 3 minutes, more preferably lower than 2 minutes, much preferably about 1 minute.

[0160] The dried textile is subsequently calendered for at least 10 seconds, preferably for about 30 seconds, at a temperature from about 140° C. to about 220° C., preferably from about 180° C. to about 220° C. The pressure of the calender can be adjusted between 0 and 6 bars so that the rolls of the calender are in contact with the dried textile. Preferably, the pressures applied during the calendering step are from 2 to 4 bars. The calendering step ensures the fixation of the finishing agent to the fibers of the textile and is faster than the conventionally used fixation step for padding-based finishing process using a high temperature (HT) fixation frame, which requires about 60 seconds at 120° C. The HT frame / machine currently used in the textile industry is a large installation (length of the heated tunnel is between 10 to 20 meters) requiring a lot of space. Thus, the calender (rotary heat press roll to roll) (e.g. commercially available calender roll to roll model RTR-2760-H, Supplier: Eastsign) used in the present process occupies also significantly lower space than the industrial available HT frame / machine.

[0161] A preferred process according to the present invention comprises the following steps:

[0162] a) applying by piezoelectric drop-on-demand inkjet printing one or more of the compositions described herein on a side of a textile, or on one or more regions of a side of a textile;

[0163] b) drying the textile to obtain a dried textile by exposure to an air having a temperature from about 120° C. to about 140° C.; and

[0164] c) calendering the dried textile for at least 10 seconds at a temperature from about 140° C. to about 220° C., preferably from about 180° C. to about 220° C., and preferably at a pressure of between 2 to 4 bars. The present finishing process may be conducted using a commercially available industrial textile printer Panthera D8 (Supplier: Swiss Performance Chemicals) and a calender. The industrial textile printer Panthera D8 and the calender require significantly less space than the currently available industrial textile padder and the corresponding HT fixation frame.

[0165] A further aspect according to the present invention is directed to a process for treatment of a textile in a textile finishing process comprising the steps:

[0166] applying by inkjet, preferably by piezoelectric drop-on demand inkjet, printing the first silicone-free and fluorine-free inkjet, preferably piezoelectric drop-on-demand inkjet, printable composition described herein, and the second silicone-free and fluorine-free inkjet, preferably piezoelectric drop-on-demand inkjet, printable composition described herein on a side of a textile, or on one or more regions of a side of a textile;

[0167] drying the textile to obtain a dried textile, preferably by exposing the textile to an air having a temperature from about 120° C. to about 140° C.; and

[0168] calendering the dried textile for at least 10 seconds at a temperature from about 140° C. to about 220° C., preferably from about 180° C. to about 220° C., and preferably at a pressure from 2 to 4 bars. The first composition and the second composition are printed simultaneously on a side of a textile, or on one or more regions of a side of a textile and mix on the surface of the textile. Following drying and calendering of the textile, the finished textile exhibits improved water-repellency and wash durability.

[0169] As used herein, the term “textile” is intended to encompass all forms of textile substrates, including woven, knitted and non-woven textile substrates. The term is intended to exclude fibrous substrates having two-dimensional rigidity such as carpets, paper and cardboard. The fibrous substrates, although sometimes referred as textiles, are internally linked in such a way that they maintain a substantially fixed two-dimensional form. Even though they may be flexible in a third dimension they are not generally free to stretch or distort within the plane of the fiber layer, as is inherent in a true textile. Preferably, the textile is more than 100 meters (e.g. 500 meters) in length and can be provided on a roll having a width of greater than 1 meter. Preferably, the textile described herein is a woven, knitted or nonwoven fabric. The fabric contains synthetic and / or natural fibers, preferably selected from cellulose fibers, elastane fibers, polyamide fibers and polyester fibers.

[0170] A fourth aspect according to the present invention is directed to a finished textile obtained by the process claimed and described herein, and a garment comprising said finished textile. The finished textile and the garment thereof exhibits softness, water-repellence and / or improved wicking properties, as well as wash durability.

[0171] To further illustrate the invention, the following examples are provided. These examples are provided with no intend to limit the scope of the invention.

Manufacturing of Textiles Finished with Textile Finishing Compositions According to the Invention

[0235] The finishing process was performed using a commercially available industrial textile printer Panthera D8 (Supplier: Swiss Performance Chemicals) and subsequent calender roll to roll (Model RTR-2760-H, Supplier: Eastsign). The Panthera D8 printer is equipped with 8 water-based Kyocera KJ4B-0300, DOD IJ Piezo Print heads.1. Evaluation of the Wicking Properties of a Textile Finished with the Textile Finishing Composition According to Example 4

[0236] The textile finishing composition according to example 4 was printed by piezoelectric drop-on-demand ink jet (printing resolution 600×600 dpi, 2 passes; printing speed 250 m2 / h; wet deposit: 15 g / m2) on a surface of a white color textile (Reference number: W-2017-992; 100% PES; knitted) and of a pink color textile (Reference number: W-2017-993; 100% PES; knitted). The printed textiles were dried by exposure to hot air (120° C.) for 90 seconds. Subsequently, the dried textiles were calendered for 35 sec at 205° C. and an average pressure of 3 bars to provide the finished textiles T1 and T2 according to the present invention (T1—white color, T2—pink color).

[0237] For comparative purposes,

[0238] a sample of the white color textile and of the pink color textile was printed as described above. To dry and fix the finishing composition to the textiles, said printed textile were kept in an oven at 100° C. for 1 minute. Comparative finished textiles C1 and C2 (C1—white color, C2—pink color) were obtained;

[0239] a sample of the white color textile (the sample was not treated with a finishing composition) was finished by drying in an oven at 100° C. for 1 minute to provide the comparative textile C3;

[0240] a sample of the white textile was finished using a standard finishing composition for improving the wicking properties of textiles and a finishing process including a padding step, a drying step by exposure to IR, and a fixation step by using a high temperature fixation frame. Comparative sample C4 was obtained.

[0241] The wicking properties of the finished textiles T1, T2, C1-C4 were evaluated in the water drop test method AATCC 79, where the absorption time in seconds was measured prior to washing, and after 1, 5 and 10 washings (laundering test ISO 5077 / 3759 / 6330; Detergent ECE 98-20 g), respectively.

[0242] The water drop test method AATTCC79, also known as absorption time—dropping test, is conventionally used in the textile industry to measure the absorption time of a drop of water by the textile fabric. To measure the absorption time, the textile fabric is held in a mandrel and a drop of water (0.1 mL) is deposited with a micropipette on the surface of the fabric. The time required by the textile fabric to absorb the drop (absorption time) is measured. The absorption time is a measure of the wicking properties of the textile fabric.

[0243] The measured absorption time (seconds) is presented in the Table below:Finished textileT1T2C1C2C3C4Prior to<1<16.783.0833.671.7washingAfter 1st<1<16.853.1534.771.7washingAfter 5th<1<17.343.4534.851.9washingAfter 10th<1<110.904.8635.602.01washing

[0244] The two finished textile fabrics T1 and T2 according to the present invention present better wicking properties and wash durability (absorption time lower than 1 second even after 10 washings) than the finished textile fabric C4 finished by padding with a standard padding composition. The comparable properties of the finished textile fabrics T1 and T2 show the versatility of the textile finishing composition and the textile finishing process. Comparison of the adsorption time measured for the finished textiles C1 and C2 and the finished textiles T1 and T2 demonstrates that the calendering step is essential for fixing the finishing composition to the textile fabric. Comparative finished textile C3 that was not printed with a textile finishing composition presents poor wicking properties as evidenced by the absorption time superior to 30 seconds.2. Evaluation of the Wicking Properties of a Textile Finished with the Textile Finishing Composition According to Example 3

[0245] The textile finishing composition according to example 3 was printed by piezoelectric drop-on-demand ink jet (printing resolution 600×600 dpi, 2 passes; printing speed 250 m2 / h; wet deposit: 15 g / m2) on a surface of the three different textile fabrics indicated below. The printed textiles were dried by exposure to hot air (120° C.) for 90 seconds. Subsequently, the dried textiles were calendered for 35 sec at 205° C. and an average pressure of 3 bars to provide the finished textiles T3-T5 (T3-finished 1st fabric, T4—finished 2nd fabric, and T5—finished 3rd fabric).1st fabricSingle Jersey,87% cotton and245 g / m213% spandex2nd fabricSingle Jersey plated,61% cotton and140 g / m239% POLYESTER3rd fabricSingle Jersey,60% cotton and125 g / m240% POLYESTER

[0246] The wicking properties of the finished textiles T4-T5 were evaluated in the above-described water drop test method AATCC 79, and in the test method for vertical wicking rate of textiles AATCC 197 (effects were measured at 30 minutes).

[0247] Test method AATCC 197 is generally used in textile industry to evaluate the ability of fabric specimens to transport liquid vertically when a cut edge is submerged. The determined vertical wicking rate represents a measure of the textile wicking properties. Cut edges of samples of the finished textiles T3-T5 (14.0×2.5 cm) were submerged in water for 30 minutes. The samples were submerged both in the warp and in the weft direction. The height of the water absorbed by the samples (wicking distance) after 30 min was measured. Wicking distances at 30 minutes superior to 13 cm are indicative of textile fabrics having excellent absorbency and wicking behavior.

[0248] The results of the tests are summarized in the Table below:Absorption timeWicking distance (cm)measured in testmeasured at 30 minutesmethod AATCC 79in test method AATCC 197(seconds )WarpWeftFinished 1st<115.317.1fabric T3Finished 2nd<117.014.3fabric T4Finished 3rd<117.016.3fabric T5

[0249] Finished textile fabrics T3-T5 according to the present invention show excellent absorbency (AATCC 79, absorption time <1 second). Finished textile fabrics T3-T5 also show excellent wicking behavior (AATCC 197) and meet the absorbency requirements of at least 13 cm for the wicking height at 30 minutes. The tests conducted in two directions of the fabric in warp and weft illustrate the excellent wicking behavior of the finished textile fabric according to the present invention. The wicking properties of the three tested textile fabrics are comparable, showing the versatility of the textile finishing composition and of the finishing process.3. Evaluation of the Softness Properties of a Textile Finished with the Textile Finishing Composition According to Example 2

[0250] The textile finishing composition according to example 2 was printed by piezoelectric drop-on-demand ink jet printing resolution 600×600 dpi, 2 passes; printing speed 250 m2 / h; wet deposit: 15 g / m2) on a surface of a variety of different textile fabrics including 100% cotton twill at a density of 160 g / m2 and a fabric garment blend 70% cotton / 30% polyester at a density of 110 g / m2. The printed textile fabrics were dried by exposure to hot air (120° C.) for 90 seconds and subsequently, calendered for 35 sec at 205° C. and an average pressure of 3 bars to provide the finished textile.

[0251] Following finishing, the softness of the finished fabric was evaluated by an expert by hand touch prior to washing and after 5, 10 and 20 washings, respectively. Compared to the untreated textile, the finished textile exhibit an excellent softness. The softness is maintained after 5, 10 and 20 washings.4. Evaluation of the Water-Repellency of a Textile Finished with the Textile Finishing Composition According to Example 1

[0252] The textile finishing composition according to example 1 was printed by piezoelectric drop-on-demand ink jet (printing resolution 600×600 dpi, 2 passes; printing speed 250 m2 / h; wet deposit: 15 g / m2) on a surface of the three different textile fabrics indicated below. The printed textiles were dried by exposure to hot air (120° C.) for 1 minute. Subsequently, the dried textiles were calendered for 3 minutes at 205° C. and an average pressure of 3 bars to provide the finished textiles T6-T8 according to the present invention (T6—finished textile fabric A, T7—finished textile fabric B, T8—finished textile fabric C).TextileDensityfabricColorCompositiong / m2Alight88% polyamide / 12%woven180greyelastaneBkaki72% polyamide / 20%woven200wool / 8% elastaneCmedium94% polyamide / 6%woven180greyelastane

[0253] The water repellence of the finished textiles T6-T8 and of the corresponding untreated textile A-C was evaluated in the AATCC 22 test method using the commercially available spray rating tester TF160 (supplier: Testex). Three samples were evaluated for each of the textile fabrics A, B and C. During the experiment, the sample of finished fabric held in a mandrel is sprayed with water. The sample is oriented at 450 with respect to the nozzle head of the spray rating tester and positioned at a distance of 150 mm under the nozzle. At the end of the experiment, the appearance of the sprayed finished fabric is compared with the appearance of the finished fabric (not sprayed) by an expert and based on visual standards, a visual rating is given to the finished fabric. A visual rating of 100 indicates that the textile fabric preserves its initial aspect (i.e. no visually detectable difference between the appearance of the textile fabric prior and after the spraying) and no water was absorbed by the textile fabric during the experiment i.e. the textile fabric has excellent water repellence. The results of the visual rating are summarized in the table below:Textile fabric ASample 1Sample 2Sample 3Untreated fabric959085Finished fabric100100100prior to washingAfter 1st wash100100100After 5th wash100100100After 10th wash10010090After 20th wash10010090Textile fabric BSample 1Sample 2Sample 3Untreated fabric959590Finished fabric100100100prior to washingAfter 1st wash100100100After 5th wash100100100After 10th wash100100100After 20th wash100100100Textile fabric CSample 1Sample 2Sample 3Untreated fabric1009590Finished fabric100100100prior to washingAfter 1st wash100100100After 5th wash100100100After 10th wash100100100After 20th wash1009590As shown by the above table, the finished textiles according to the present invention provide excellent water repellency even after 20 washings. The rating of “100” indicates no absorption of water by the tested fabric. The water repellency does not decrease after 1 wash, 5× washes, 10× washes and 20× washes, which confirms the excellent wash durability of the finishing obtained with the inventive finishing process. Comparable results were obtained for the three fabrics attesting the versatility of the water-repellent finishing composition and the finishing process according to the present invention.5. Evaluation of the Reliability of the Finishing CompositionThe reliability of the textile finishing compositions according to examples 1 to 4 and of the textile finishing process was tested on a piezoelectric drop-on-demand inkjet printer Panthera S4 (supplier: Swiss Performance Chemicals) equipped with 4 water-based DOD IJ Piezo Kyocera KJ4B-0300 printheads and on a piezoelectric drop-on-demand inkjet printer Panthera D8 (supplier: Swiss Performance Chemicals) equipped with 8 water-based DOD IJ Piezo Kyocera KJ4B-0300 printheads. To visualize the quality of the printing, a magenta sublimation ink (SwissJet SP7 from Swiss Perfomance Chemicals, Switzerland) was added to each of the textile finishing compositions according to examples 1 to 4 (99 wt-% textile finishing composition; 1 wt-% magenta sublimation ink).

[0256] The so obtained finishing compositions were printed bi-directionally at 240 m2 / h on a white color textile fabric (Natte 2 / 1, 100% PES, 218 g / m2) without using automatic cleaning up program. Different lengths (20 m, 100 m, 200 m, and 500 m) of textile were printed and the quality of the printing was visually checked. A prime test was conducted prior to printing each of the desired lengths (20 m, 100 m, 200 m and 500 m) to check whether all nozzles are correctly ejecting, as well as after printing each of the desired lengths to detect potential nozzles clogging.

[0257] The above-summarized printing procedure was repeated after leaving the finishing compositions in the printer for 3 days.

[0258] After exposure to hot air (120° C.) for 90 seconds and subsequent calendering for 35 sec at 205° C. and an average pressure of 3 bars, the printed textile was examined. No errors were detected on the printed textile. Moreover, no nozzles clogging occurred.
