Description

Technical Field

[0001] The technical field to which the present invention relates is textile finishing compositions, in particular textile softening compositions, water repellent finishing compositions and textile finishing compositions for improving wicking properties, and methods for textile finishing. Background Art

[0002] Today, the textile industry uses a wide range of industrial finishing processes. Consequently, textiles frequently undergo a finishing process that imparts certain properties to the textile thus finished. These finishing processes or methods can be mechanical (e.g., corundum napping, compression shrinking, shearing) or chemical and provide the product with its final appearance and properties.

[0003] Chemical finishing involves the modification of textile fibers through chemical action. Chemical finishing is typically performed by padding, during which the textile is completely immersed in a textile finishing composition and subsequently undergoes repeated cycles of drying (typically by exposure to IR), fixing (typically by using high-temperature fixing frames), and condensation. The padding process results in the consumption of significant resources (such as finishing composition, water, and energy).

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

[0005] A textile softening composition is a textile finishing composition that makes the textile soft, fluffy, and antistatic, thereby providing it with a soft hand. Fabric softening compositions contain a softening agent or softening agent that reduces the coefficient of friction between fibers, resulting in surface softness and a lubricating effect on the fibers. Currently, silicones (polysiloxanes), including epoxy- and / or amino-modified polysiloxanes, polyether-modified polysiloxanes containing polyether-reactive groups grafted onto the side chains of the polysiloxane chain, and linear multi-block polysiloxane copolymers, are widely used as softening agents or softening agents in textile softening compositions to impart softness to the treated textiles and improve the wear feel. Silicone softeners are synthetic compounds whose synthesis generally requires a large amount of energy. Moreover, the production of textile softening compositions using silicone softeners has a high carbon footprint because a large amount of energy is required to obtain the required emulsion. In addition, silicone softeners are not biodegradable and accumulate in the environment.

[0006] Water-repellent finishing compositions provide water-repellent properties to treated textiles. Water-repellent finishing compositions typically contain fluorinated water repellents, such as per- or polyfluoroalkyl substances (PFAS). Fluorinated compounds, particularly PFAS, are known to accumulate in the environment, drinking water, and food, and are harmful to the environment and humans.

[0007] Consumers' expectations for the textiles they use and the methods of making them have increased dramatically in recent years. In addition to meeting their preferences in terms of appearance and performance, the textiles must also be healthy and environmentally friendly and be produced using environmentally friendly manufacturing methods.

[0008] In view of the shortcomings of currently available textile finishing compositions and methods, in particular with respect to the non-biodegradability and toxicity of the finishing agents, as well as water and energy consumption, there is a need for textile finishing compositions comprising healthy and environmentally friendly ingredients (i.e., biodegradable ingredients that are harmless to humans and the environment) that can be applied to textiles by methods other than padding. Such compositions should also meet specific requirements for textile finishing compositions, such as wash durability (i.e., the retention of the properties imparted by the finishing composition to the textile after repeated washing cycles), high affinity for textile fibers, stability during storage, stability during chemical treatments, stability after attachment to the textile, and no change in the color of the textile.

[0022] Detailed description of the invention

[0023] The object according to the present invention is therefore to address the need for a textile finishing composition comprising healthy and environmentally friendly ingredients that can be applied to the textile by methods other than padding and which meets the specific requirements for textile finishing compositions, such as wash fastness, high affinity for textile fibers, stability during storage, stability during chemical treatments, and stability after fixation to the textile, as well as non-altering of the color of the textile (the composition itself is colorless, i.e. has no color detectable by the naked eye, and after fixation does not alter the color of the treated textile).

[0024] Hereinafter, the present invention will be described in more detail.

[0025] When the present specification mentions “preferred” embodiments / features, combinations of these “preferred” embodiments / features are also considered to be disclosed, as long as the specific combination of “preferred” embodiments / features makes technical sense.

[0026] Unless otherwise stated, the following definitions apply to this specification:

[0027] As used herein, the terms “a,” “an,” “the” and similar referents used in the context of the invention (especially in the context of the claims) are to be construed to cover both the singular and the plural, unless otherwise indicated herein or clearly contradicted by context.

[0028] As used herein, the term "and / or" means that all or only one of the elements of the 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 encompasses the possibility that B is not present, i.e., "only A, but not B."

[0029] As used herein, the terms "including," "containing," and "comprising" are used herein in their open, non-limiting sense. It is understood that the various embodiments, preferences, and ranges can be combined in any manner. Thus, for example, a solution comprising compound A may contain other compounds in addition to A. However, the term "comprising," as a specific embodiment thereof, also encompasses the more restrictive meanings of "consisting essentially of" and "consisting of," so that, for example, a "solution comprising A, B, and optionally C" may also consist (essentially) of A and B, or (essentially) of A, B, and C. As used herein, the transition phrase "consisting essentially of" (and grammatical variations) is to be interpreted as encompassing the recited materials or steps as well as those that do not materially affect the basic and novel characteristics of the claimed invention. Thus, the term "consisting essentially of" should not be interpreted as being equivalent to "comprising."

[0030] As used herein, the term "about" means that the amount or value in question can be the specified specific value or some other value in its vicinity. Generally, the term "about" indicating a value is intended to indicate a range within ±5% of that value. As an example, the phrase "about 100" indicates a range of 100 ± 5, i.e., a range from 95 to 105. Preferably, the range indicated by the term "about" indicates a range within ±3%, preferably within ±1%, of the value. Generally, when the term "about" is used, it is expected that similar results or effects according to the present invention can be obtained within a range of ±5% of the indicated value.

[0031] Surprisingly, it has been found that a silicone-free and fluorine-free textile finishing composition can be used as a textile finishing composition for imparting softness, water repellency and / or improved wicking properties to textiles, the silicone-free and fluorine-free textile finishing composition comprising, preferably consisting of:

[0032] i) from about 10.0% to about 30.0% by weight of 1,2,3-propanetriol, preferably of plant origin;

[0033] ii) from about 0.05% to about 10.0% by weight of a surfactant, preferably a biodegradable surfactant;

[0034] iii) from about 1.0% to about 10% by weight of a finish selected from the group consisting of plant-derived oils, plant-derived waxes, beeswax, and esterquats, provided that if the finish is a plant-derived wax or beeswax, the composition may further comprise a wax extender, wherein preferably, the wax extender is a blocked isocyanate; and

[0035] iv) optionally, a thickener and / or a biocide and / or a pH adjuster; and

[0036] v) water, making up to 100% by weight; the % by weight are based on the total weight of the composition. Advantageously, most of the ingredients contained in the composition are natural and biodegradable. Furthermore, the composition is free of silicones and fluorinated compounds, which are known to be non-biodegradable and even toxic. The textile finishing compositions described and claimed herein are colorless, i.e., they do not contain pigments and / or dyes having a color detectable to the naked eye. In other words, the textile finishing compositions described and claimed herein are pigment-free and dye-free.

[0037] As is well known to those skilled in the art, a finish is a substance that changes the properties of a textile other than its color. The properties imparted to the textile depend on the finish contained in the finishing composition. In the present invention, the finish is a finish comprising a fatty acid ester (i.e., a finish comprising one or more fatty acid esters) and is selected from plant-derived oils, plant-derived waxes, beeswax, and esterquats.

[0038] The term "silicone-free composition" refers to a composition that does not contain silicone / polysiloxane. As used herein, the terms "silicone" and "polysiloxane" encompass all polymers containing polysiloxane moieties, including but not limited to silicone / polysiloxane oils, modified polysiloxanes such as epoxy and / or amino modified polysiloxanes, and polyether modified polysiloxanes, and linear multi-block polysiloxane copolymers.

[0039] The term "fluorine-free composition" refers to a composition that does not contain fluorinated compounds such as per- or polyfluoroalkyl substances (PFAS).

[0040] The present composition may include up to 1.0% by weight of a thickener. As known to those skilled in the art, a thickening agent or thickener is a substance that increases the viscosity of a liquid without substantially changing the other properties of the liquid. Those skilled in the art have the ability to adjust the amount of the thickener to obtain the viscosity required for the textile finishing composition. Preferably, the thickener is a polysaccharide of plant origin (e.g., starch, plant gum). Examples of suitable thickeners include, but are not limited to, carob gum (also known as locust bean gum or carob gum (carob gum), which contains at least 75% galactomannans), such as Carob EXC 25, guar gum, carrageenan, and algin from commercially available Swiss HEIQ. Advantageously, the thickener is commercially available and can be easily dispersed in water when mixed.

[0041] In addition, the composition of the present invention may contain up to 0.5% by weight of a biocide. The biocide prevents biological deterioration of the textile, helps prevent the spread of infectious diseases without the need for frequent sterilization, and ensures the stability of the textile finishing composition for at least 12 months. Any biocide conventionally used in the textile industry is suitable for use in the textile finishing composition of the present invention. Such biocides include, but are not limited to, 1,2-benzisothiazolin-3-one (commercially available from Zeneca Specialties in the form of a solution sold under the trade name Proxel GXL), organocopper compounds, organotin compounds, chlorinated phenols, silver-based microbial agents, and metal-based inorganic compounds, such as zinc oxide, zinc salts, and copper salts.

[0042] Preferably, the textile finishing composition has a pH of 5 to 9. The pH value depends on the intended use (e.g., softening, water repellency) and stability conditions of the finishing composition, as well as the properties and effects achieved on the fabric. If desired, the textile finishing composition may further comprise up to 0.5% by weight of a pH adjuster, preferably a pH adjuster of plant origin. Preferably, the pH adjuster is selected from acetic acid, citric acid, ascorbic acid, malic acid, and the like. Preferably, citric acid is used to adjust the pH of the composition to a pH range of 5-7, while acetic acid is used to adjust the pH of the composition to a pH range of 7-9.

[0043] The textile finishing composition according to the present invention can be applied to textiles by coating, spraying or inkjet printing.

[0044] In a preferred embodiment, the textile finishing composition claimed herein is an inkjet printable composition, preferably a piezoelectric drop-on-demand inkjet printable composition. The piezoelectric drop-on-demand inkjet printable composition is a composition that is printed at 25°C and a shear rate of 200-400s -1The textile finishing composition preferably has a viscosity of 2-10 cP, more preferably 6-7 cP, as measured using a Brookfield DVN viscometer, flat cone, 50 RPM. To avoid clogging of the print head, the particle size of any solid components present in the textile finishing composition is preferably less than 1 μm. As used herein, a particle size of less than 1 μm means a D99 diameter of less than 1 μm. The use of inkjet printing (preferably piezoelectric drop-on-demand inkjet printing) enables the selective application of a well-defined amount of the finishing composition to the surface of a textile or to one or more areas of a textile surface. Due to the precise dosing of the textile finishing composition achieved by inkjet printing, the volume of the textile finishing composition applied is significantly lower than that required by padding (4-6 times lower), and a constant deposit of the finishing composition is applied over the entire surface to be treated, resulting in properties that cannot be achieved by padding methods. In addition, the volume of wastewater generated in this finishing method is reduced by 4-6 times compared to padding finishing methods. In addition, the use of this finishing method significantly reduces energy consumption. Advantageously, the compositions described and claimed herein are ready-to-use, i.e., they do not need to be prepared on-site and before each finishing process, as is required for finishing methods that include a padding step. The textile finishing compositions described and claimed herein are compatible with commercially available industrial textile printing presses (e.g., Panthera D8 or Panthera S4 from Swiss Performance Chemicals; LaRIO from MS Printing Solutions), requiring significantly less space and manual intervention than currently available industrial textile padders.

[0045] A preferred embodiment according to the present invention is directed to a textile finishing composition as described and claimed herein, wherein

[0046] iii-1) The finishing agent is a plant-derived oil, and the composition comprises from about 1.0% to about 6.0% by weight of the plant-derived oil. This textile finishing composition is particularly useful for imparting improved softness and / or wicking properties to textiles. The term "plant-derived oil" encompasses any oil or triglyceride extracted from a plant (e.g., a fruit or seed). 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, grapeseed oil, hazelnut oil, oat oil, olive oil, palm oil, palm kernel oil, peanut oil, rapeseed oil, safflower oil, sesame oil, linseed oil, soybean oil, star palm 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, moringa oil. oil), peach kernel oil, pistachio oil, raspberry oil, rice bran oil, rosehip oil, soybean oil (soyaoil), wheat germ oil, yanggu oil, algae oil; hydrogenated derivatives thereof, and mixtures thereof.

[0047] An alternative embodiment according to the present invention relates to a textile finishing composition as described and claimed herein, wherein the finishing agent is a wax of plant origin or beeswax and the composition comprises from about 6.5% to about 10% by weight of said wax of plant origin or said beeswax. Such a finishing composition is particularly useful for imparting water repellency to textiles. Advantageously, the composition as described and claimed herein does not contain paraffin wax, which is a non-biodegradable ingredient widely used in water-repellent textile finishing compositions. Such a composition may further comprise a wax extender to improve the performance of the wax by increasing the water repellency and / or wash durability imparted by the wax to the textile. Therefore, a preferred embodiment according to the present invention relates to a textile finishing composition as described and claimed herein, wherein

[0048] iii-2) The finishing agent is a plant-derived wax or beeswax and the composition comprises from about 6.5 wt% to about 10 wt% of the plant-derived wax or the beeswax, and from about 1.5 wt% to about 4.5 wt% of a wax extender.

Examples of suitable plant waxes include, but are not limited to, carnauba wax, soy wax, jojoba wax, candelilla wax, rice wax, sugarcane wax, and mixtures / blends thereof. As is well known in the art, carnauba wax (also known as palm wax) is a common type of plant wax that is harvested from plant leaves by drying palm leaves and beating them to loosen the wax. The carnauba wax contains aliphatic esters (about 40% by weight), 4-hydroxycinnamic acid Diesters (about 21.0 wt. %), ω-hydroxycarboxylic acids (about 13.0 wt. %), and fatty alcohols (about 12 wt. %). The compounds are primarily derived from acids and alcohols in the C26-C30 range. In one embodiment, the plant-derived wax is carnauba wax and the finishing composition does not contain a wax extender.

[0050] In a preferred embodiment, the plant-derived wax is candelilla wax. Candelilla wax is derived from the small leaves of the Candelilla shrub, which is native to northern Mexico and the southwestern United States. It is harvested by immersing the entire plant in acidified boiling water. The wax then floats to the surface of the boiling water.

[0051] As is known in the art, wax extenders are substances used in combination with waxes to improve the properties of the wax, for example by increasing the water repellency or wash resistance of the treated textile.

[0088] In a preferred embodiment, the wax extender is a blocked isocyanate, preferably selected from the group consisting of blocked isocyanates having a molecular weight of less than 2000 g / mol. Blocked isocyanates are well known in the art and are commercially available. Suitable blocked isocyanates are based on isocyanate chemistry, in which a polyfunctional isocyanate has been reacted with a blocking agent, as described below, to produce a product that is inert at room temperature and lacks isocyanate functionality. Isocyanate functionality can be restored by heating the blocked isocyanate to above its activation temperature, at which point the blocking effect is released and the isocyanate groups become available to react with suitable functional groups. During the textile finishing process, increasing the surface temperature of the textile can trigger this activation and subsequent crosslinking reactions within the polymer produced after activation and between the polymer produced after activation and the fiber surface in the textile.

[0089] Blocking agents for isocyanates are known per se and include organic compounds having at least one active hydrogen; they can be selected by a person skilled in the art. Advantageously, the blocking agent is selected from compounds such as alcohols, lactams, phenols, oximes and pyrazoles. The blocking agent can also be selected from plant-based phenolic compounds to provide a system with an increased biocarbon content and a higher degree of sustainability. This type of blocking agent includes cardanol (3-pentadeca-dienylphenol), which can be derived from cashew nut shell liquid.

[0090] Advantageously, the isocyanate is selected from the class of aliphatic isocyanates including hexamethylene diisocyanate, isophorone diisocyanate, trimethylhexamethylene diisocyanate, hydrogenated diphenylmethane 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 below 2000 g / mol.

[0091] The blocked isocyanates described herein are preferably obtained by reacting an isocyanate, preferably an isocyanate selected from aliphatic isocyanates (having a molecular weight below 2000 g / mol), with a reagent selected from alcohols, lactams, phenols, oximes and pyrazoles, preferably 3,5-dimethylpyrazole.

[0092] Commercial examples of suitable blocked isocyanates include: blocked isocyanate TTL (available from Beyond Surface Technologies AG), blocked isocyanates 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).

[0153] According to a second aspect of the present invention, there is provided a kit for finishing textiles, comprising:

[0154] 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. % of 1,2,3-propanetriol, preferably 1,2,3-propanetriol of plant 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 plant origin or beeswax as described herein; optionally, a thickener as described herein and / or a biocide as described herein and / or a pH adjuster as described herein; and water to 100 wt. %; and

[0156] The first non-silicone-containing and non-fluorine-containing inkjet, preferably piezoelectric drop-on-demand inkjet printable composition and the second non-silicone-containing and non-fluorine-containing inkjet, preferably piezoelectric drop-on-demand inkjet printable composition are simultaneously printed onto the surface of a textile, or onto one or more areas of the surface of a textile, and mixed on the surface of the textile. After drying the textile and calendering as described herein, the finished textile exhibits improved water repellency and wash durability.

[0157] According to a third aspect of the present invention there is directed to a method for treating textiles using the composition described and claimed herein in a textile finishing method, preferably comprising the steps of:

[0158] a) applying one or more compositions described herein to a textile;

[0159] b) drying the textile to obtain a dried textile, preferably by exposing the textile to air at a temperature of about 120° C. to about 140° C.; and

[0160] c) calendering the dried textile at a temperature of about 140° C. to about 220° C., preferably about 180° C. to about 220° C., and preferably at a pressure of 2-4 bar for at least 10 seconds.

[0161] Preferably, the finishing process described and claimed herein does not comprise a padding step.Thus, in step a), the one or more finishing compositions are preferably applied to the textile by coating, spraying or inkjet printing.

[0162] 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 the selective application of a well-defined amount of the one or more finishing compositions to a surface of a textile or to one or more areas of a surface of a textile. Thus, the finishing method of the present invention allows the finishing of a single side of a textile or certain areas of a surface of a textile. This selective finishing cannot be achieved by padding. As is known in the art, the term "side" refers to the front or back side of a textile. Moreover, the present finishing method enables the simultaneous application of multiple finishing compositions. Due to the precise dosing of the textile finishing composition achieved by inkjet printing, the volume of the textile finishing composition applied is significantly lower than that required by padding finishing, and a constant volume of the finishing composition is applied over the entire surface to be treated. In addition, the volume of wastewater generated and the energy consumed in this finishing method are significantly reduced compared to padding finishing methods.

[0163] In a preferred embodiment, the one or more compositions are applied by piezoelectric drop-on-demand inkjet printing. The low drop volumes (5 pL, 7 pL, 12 pL, 18 pL) and the precise deposition achieved by the piezoelectric drop-on-demand inkjet print head result in a uniform (constant wet deposit across the entire treated surface of the textile) finish of the textile.

[0164] In step b) of the present finishing method, the textile is dried to evaporate the water contained in the finishing composition and provide a dried textile. This step is preferably achieved by exposing the coated / sprayed / inkjet printed textile to air at a temperature of about 120° C. to about 140° C. The exposure time depends on the surface density (g / m 2) of the deposited finishing composition.2 ) and the temperature used, and is preferably less than 3 minutes, more preferably less than 2 minutes, very preferably about 1 minute.

[0165] The dried textile is then calendered at a temperature of about 140°C to about 220°C, preferably about 180°C to about 220°C, for at least 10 seconds, preferably about 30 seconds. The calender pressure can be adjusted between 0 and 6 bar so that the calender rollers are in contact with the dried textile. Preferably, the pressure applied during the calendering step is 2 to 4 bar. This calendering step ensures that the finish is fixed to the textile fibers and is faster than the fixing step conventionally used in padding-based finishing methods using high-temperature (HT) fixing frames, which typically require about 60 seconds at 120°C. HT frames / machines currently used in the textile industry are large devices (heating tunnels of 10-20 meters in length) and require a large amount of space. Therefore, the calender (rotating hot press roll-to-roll) used in the present method (e.g., the commercially available calender roll-to-roll model RTR-2760-H, supplier: Eastsign) also takes up significantly less space than industrially available HT frames / machines.

[0166] A preferred method according to the present invention comprises the following steps:

[0167] a) applying one or more compositions as described herein to a surface of a textile or to one or more areas of a surface of a textile by piezoelectric drop-on-demand inkjet printing;

[0168] b) drying the textile by exposing it to air at a temperature of about 120° C. to about 140° C. to obtain a dried textile; and

[0169] c) calendering the dried textile at a temperature of about 140° C. to about 220° C., preferably about 180° C. to about 220° C., and preferably at a pressure of 2-4 bar for at least 10 seconds. This finishing method can be carried out using a commercially available industrial textile printing press, the Panthera D8 (supplier: Swiss Performance Chemicals), and a calender. The Panthera D8 and the calender require significantly less space than currently available industrial textile padders and corresponding HT fixing frames.

[0170] According to a further aspect of the present invention there is directed to a method for treating a textile in a textile finishing process, comprising the steps of:

[0171] applying a first silicone-free and fluorine-free inkjet, preferably piezoelectric drop-on-demand inkjet-printable composition as described herein and a second silicone-free and fluorine-free inkjet, preferably piezoelectric drop-on-demand inkjet-printable composition as described herein to a side of a textile, or to one or more areas of a side of a textile, by inkjet printing, preferably by piezoelectric drop-on-demand inkjet printing;

[0172] drying the textile to obtain a dried textile, preferably by exposing the textile to air at a temperature of about 120° C. to about 140° C.; and

[0173] The dried textile is calendered at a temperature of about 140°C to about 220°C, preferably about 180°C to about 220°C, and preferably at a pressure of 2-4 bar for at least 10 seconds. The first composition and the second composition are simultaneously printed onto the surface of the textile, or onto one or more areas of the surface of the textile, and mixed on the surface of the textile. After drying and calendering the textile, the finished textile exhibits improved water repellency and wash durability.

[0174] As used herein, the term "textile" is intended to encompass all forms of textile substrates, including woven, knitted and nonwoven textile substrates. The term is intended to exclude fiber substrates with two-dimensional rigidity, such as carpets, paper and cardboard. Although the fiber substrate is sometimes also referred to as a textile, its internal connection mode keeps it in a substantially fixed two-dimensional form. Even if they may be flexible in the third dimension, they are generally unable to freely stretch or deform in the fiber layer plane, which is inherent to real textiles. Preferably, the length of the textile is greater than 100 meters (such as 500 meters) and can be provided on a roll greater than 1 meter in width. Preferably, textiles as described herein are woven, knitted or nonwoven fabrics. The fabric comprises synthetic and / or natural fibers, preferably selected from cellulose fibers, elastic fibers, polyamide fibers and polyester fibers.

[0175] According to a fourth aspect of the present invention, the finished textile obtained by the method described and claimed herein, and a garment comprising the finished textile, exhibiting softness, water repellency and / or improved wicking properties, and wash durability.

[0259]

[0260] II. Production of Textiles Finished with the Textile Finishing Composition According to the Invention

[0261] The finishing process was carried out using a commercially available industrial textile printing press Panthera D8 (supplier: SwissPerformance Chemicals) followed by a calender roll-to-roll (model RTR-2760-H, supplier: Eastsign).The Panthera D8 printer was equipped with 8 water-based Kyocera KJ4B-0300, DOD IJ piezoelectric print heads.

[0262] 1. Evaluation of the wicking properties of textiles finished with the textile finishing composition according to Example 4

[0263] The surfaces of white textile (label: W-2017-992; 100% PES; knitted) and pink textile (label: W-2017-993; 100% PES, knitted) were printed by piezoelectric drop-on-demand inkjet printing (printing resolution 600x600 dpi, 2 passes; printing speed 250 m 2 / h; wet deposition: 15g / m 2 ) The textile finishing composition according to Example 4. The printed textile was dried by exposure to hot air (120° C.) for 90 seconds. Subsequently, the dried textile was calendered at 205° C. and an average pressure of 3 bar for 35 seconds to provide finished textiles T1 and T2 according to the present invention (T1 - white, T2 - pink).

[0264] For comparison purposes,

[0265] - Samples of white and pink textiles were printed as described above. To dry and fix the finishing composition on the textile, the printed textiles were kept in an oven at 100° C. for 1 minute. Comparative finished textiles C1 and C2 were obtained (C1 - white, C2 - pink);

[0266] - a white textile sample (this sample was not treated with the finishing composition) was finished by drying in an oven at 100° C. for 1 minute to provide comparative textile C3;

[0267] A white textile sample was finished using a standard finishing composition for improving the wicking properties of textiles, the finishing process comprising a padding step, a drying step with exposure to IR and a fixing step using a high temperature fixing frame. Comparative sample C4 was obtained.

[0268] 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 before washing and after 1, 5 and 10 washes (washing test ISO 5077 / 3759 / 6330; detergent ECE 98-20 g).

[0269] The water drop test method AATTCC79 (also known as the absorption time-drip test) is commonly used in the textile industry to measure the absorption time of a textile fabric for a water drop. To measure the absorption time, the textile fabric is held on a mandrel and a water droplet (0.1 mL) is deposited on the fabric surface using a micropipette. The time required for the textile fabric to absorb the droplet (absorption time) is measured. The absorption time is an indicator of the wicking performance of the textile fabric.

[0270] The following table shows the measured absorption times in seconds:

[0271]

[0272] Compared to the treated textile fabric C4, which was treated by padding with a standard padding composition, the two treated textile fabrics T1 and T2 according to the invention had better wicking properties and wash durability (absorption times of less than 1 second even after 10 washes). The comparable performance of the treated textile fabrics T1 and T2 demonstrates the versatility of the textile finishing composition and the textile finishing method. A comparison of the absorption times measured for the treated textiles C1 and C2 and the treated textiles T1 and T2 shows that the calendering step is essential for fixing the finishing composition to the textile fabric. The comparative treated textile C3, which was not printed with the textile finishing composition, had poor wicking properties, as evidenced by an absorption time of greater than 30 seconds.

[0273] 2. Evaluation of the wicking properties of textiles finished with the textile finishing composition according to Example 3

[0274] The following three different textile fabrics were printed on the surface by piezoelectric drop-on-demand inkjet printing (printing resolution 600x600 dpi, 2 passes; printing speed 250 m / s) 2 / h; wet deposition: 15g / m 2) The textile finishing composition according to Example 3. The printed textile was dried by exposure to hot air (120° C.) for 90 seconds. Subsequently, the dried textile was calendered at 205° C. and an average pressure of 3 bar for 35 seconds to provide finished textiles T3-T5 (T3 - finished first fabric, T4 - finished second fabric, T5 - finished third fabric).

[0275] Fabric 1 <![CDATA[Single-sided Jersey, 245g / m 2 > 87% cotton and 13% spandex Fabric 2 <![CDATA[Single-sided plating jersey, 140g / m 2 > 61% cotton and 39% polyester Fabric 3 <![CDATA[Single-sided Jersey, 125g / m 2 > 60% cotton and 40% polyester

[0276] The wicking properties of the finished textiles T4-T5 were evaluated according to the above-mentioned water drop test method AATCC 79 and the test method for vertical wicking rate of textiles AATCC 197 (performance was measured at 30 minutes).

[0277] Test method AATCC 197 is commonly used in the textile industry to evaluate the ability of a fabric sample to vertically transport liquid when the cut edge is immersed. The vertical wicking rate determined represents a measure of the wicking performance of the textile. The cut edges of finished textile T3-T5 samples (14.0 x 2.5 cm) are immersed in water for 30 minutes. The samples are immersed in both the warp and weft directions. The height of the water absorbed by the sample after 30 minutes (wicking distance) is measured. A wicking distance of more than 13 cm at 30 minutes indicates that the textile fabric has excellent absorbency and wicking properties.

[0278] The test results are summarized in the following table:

[0279]

[0280] Finished textile fabrics T3-T5 according to the present invention exhibited excellent absorbency (AATCC 79, absorption time <1 second). Finished textile fabrics T3-T5 also exhibited excellent wicking properties (AATCC 197) and met the absorbency requirement of a wicking height of at least 13 cm at 30 minutes. Tests conducted in both the warp and weft directions of the fabrics showed that the finished textile fabrics according to the present invention had excellent wicking properties. The wicking properties of the three tested textile fabrics were comparable, demonstrating the versatility of the textile finishing composition and finishing method.

[0281] 3. Evaluation of the softness properties of textiles finished with the textile finishing composition according to Example 2

[0282] In a variety of textile fabrics (including density 160g / m 2 100% cotton twill fabric and density is 110g / m 2The surface of 70% cotton / 30% polyester blended garment fabric (fabric garment blend) was printed by piezoelectric drop-on-demand inkjet printing (printing resolution 600x600dpi, 2 passes; printing speed 250m 2 / h; wet deposition: 15g / m 2 ) The textile finishing composition according to Example 2. The printed textile fabric was dried by exposure to hot air (120° C.) for 90 seconds and subsequently calendered at 205° C. and an average pressure of 3 bar for 35 seconds to provide a finished textile.

[0283] After finishing, the softness of the treated textiles was evaluated by hand by experts before washing and after 5, 10, and 20 washes. Compared to untreated textiles, the treated textiles showed superior softness. The softness was maintained after 5, 10, and 20 washes.

[0284] 4. Evaluation of water repellency of textiles finished with the textile finishing composition according to Example 1

[0285] The following three different textile fabrics were printed on the surface by piezoelectric drop-on-demand inkjet printing (printing resolution 600x600 dpi, 2 passes; printing speed 250 m / s) 2 / h; wet deposition: 15g / m 2 ) The textile finishing composition according to Example 1. The printed textile was dried by exposure to hot air (120° C.) for 1 minute. Subsequently, the dried textile was calendered at 205° C. and an average pressure of 3 bar for 3 minutes to provide finished textiles T6-T8 according to the present invention (T6 - finished textile fabric A, T7 - ​​finished textile fabric B, T8 - finished textile fabric C).

[0286] Textile fabrics color composition <![CDATA[Density g / m 2 > A Light gray 88% Polyamide / 12% Elastane Woven 180 B Khaki 72% Polyamide / 20% Wool / 8% Elastane Woven 200 C Medium gray 94% Polyamide / 6% Elastane Woven 180

[0287] The water repellency of treated textiles T6-T8 and corresponding untreated textiles AC was evaluated using a commercially available spray rating tester TF160 (supplier: Testex) according to AATCC test method 22. Three samples of each of textile fabrics A, B, and C were evaluated. During the experiment, a sample of the treated fabric held in a mandrel was sprayed with water. The sample was oriented at 45° relative to the nozzle head of the spray rating tester and was located at a distance of 150 mm below the nozzle. At the end of the experiment, the experts compared the appearance of the sprayed treated fabric with the appearance of the treated fabric (unsprayed) and visually rated the treated fabrics according to visual criteria. A visual rating of 100 indicates that the textile fabric retained its initial appearance (i.e., there was no visually detectable difference between the appearance of the textile fabric before and after spraying) and that the textile fabric did not absorb water during the experiment, i.e., the textile fabric had excellent water repellency.

[0288] The results of the visual ratings are summarized in the following table:

[0289] Textile Fabric A Sample 1 Sample 2 Sample 3 Untreated fabric 95 90 85 Finished fabrics before washing 100 100 100 After the first wash 100 100 100 After the 5th wash 100 100 100 After the 10th wash 100 100 90 After the 20th wash 100 100 90

[0290] Textile Fabric B Sample 1 Sample 2 Sample 3 Untreated fabric 95 95 90 Finished fabrics before washing 100 100 100 After the first wash 100 100 100 After the 5th wash 100 100 100 After the 10th wash 100 100 100 After the 20th wash 100 100 100

[0292] As shown in the table above, the finished textiles according to the present invention provided excellent water repellency, even after 20 washes. A rating of "100" indicates that the tested fabric absorbed no water. The water repellency did not decrease after 1 wash, 5 washes, 10 washes, and 20 washes, demonstrating the excellent wash durability of the finish achieved using the finishing method of the present invention. Comparable results were achieved for the three fabrics, demonstrating the versatility of the water repellent finishing composition and finishing method according to the present invention.

[0293] 5. Evaluation of the reliability of the finishing composition

[0294] The reliability of the textile finishing compositions and textile finishing methods according to Examples 1 to 4 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 print heads and a pressure-sensitive drop-on-demand inkjet printer Panthera D8 (supplier: Swiss Performance Chemicals) equipped with 8 water-based DOD-IJ Piezo Kyocera KJ4B-0300 print heads.

[0295] To visualize the print quality, magenta sublimation ink (SwissJet SP7, from SwissPerfomance 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).

[0296] The finishing composition thus obtained was 240 m 2 / h bidirectional printing on white textile fabric (Natté 2 / 1, 100% PES, 218g / m 2 ) without using the automatic cleaning program. Textiles of different lengths (20m, 100m, 200m and 500m) were printed and the print quality was visually inspected. A preliminary test was performed before printing each required length (20m, 100m, 200m and 500m) to check that all nozzles were properly jetting, and after printing each required length to check for potential nozzle blockages.

[0297] After the finishing composition had been in the press for 3 days, the printing process summarized above was repeated.

[0298] After exposure to hot air (120° C.) for 90 seconds and subsequent calendering at 205° C. and an average pressure of 3 bar for 35 seconds, the printed textile was tested. No errors were detected on the printed textile. Furthermore, no nozzle clogging occurred.
