Description

Technical Field

[0001] The present invention relates to an aqueous dispersion composition for fiber processing.

Background Art

[0002] Conventionally, in order to impart various functions such as water repellency and stain resistance to fibers, fibers are often processed with various fiber processing agents.

[0003] For example, as a method for imparting water repellency to fibers, treatment with a water repellent is common. As the water repellent, a fluorine-based water repellent having a fluorine atom is particularly well-known. By treating a fiber product or the like with such a fluorine-based water repellent, a fiber product having water repellency imparted to its surface is known.

[0004] The above-mentioned fluorine-based water repellent is generally produced by polymerizing or copolymerizing a monomer having a fluoroalkyl group. Although a fiber product treated with a fluorine-based water repellent exhibits excellent water repellency, the monomer having a fluoroalkyl group is hardly decomposable, so there is a problem in terms of the environment.

[0005] Therefore, in recent years, research has been advanced on non-fluorine-based water repellents that do not contain fluorine atoms. For example, Patent Document 1 proposes a water repellent composed of a specific non-fluorine-based polymer containing a (meth)acrylate ester having 12 or more carbon atoms in the ester moiety as a monomer unit. Further, Patent Document 2 proposes a soft water repellent containing an amino-modified silicone and a polyfunctional isocyanate compound. However, fibers processed with these water repellents have a problem that the frictional resistance between the fibers becomes very small, so the slipperiness (the performance of preventing the seam from slipping during wearing in clothing or the like) decreases. In addition, when the processed fibers are bent or rubbed, cracks or peeling occur in the water repellent film on the fibers, and a so-called chalk mark occurs where the part becomes white due to diffuse reflection of light, and the appearance is greatly impaired.

[0006] In addition, as for imparting functionality to other fibers, stain-proofing treatment can be mentioned. Conventionally, various stain-proofing treatment means have been proposed to prevent stains from adhering to fibers or to make the adhered stains easier to remove.

[0007] As the above-mentioned stain-proofing treatment, for example, non-fluorine-based SG (Soil Guard; performance that makes it difficult for stain components to adhere to the fiber surface) treatment in which the fiber surface is coated with a stain-resistant agent such as a silicone-based processing agent is known. If this SG treatment is applied to the fiber, it becomes difficult for liquid stains to adhere to the fiber surface. However, in such SG treatment, since the frictional resistance between the fibers becomes small, there is a problem that the slipperiness of the fibers decreases, similar to the above-mentioned water-repellent treatment.

[0008] In Patent Document 3, a stain-proofing agent excellent in SG property has been proposed by attaching polysaccharides and modified organosilicate fine particles to a fiber material. However, the slipperiness of the fiber has not been considered.

[0041] Component (A) can be obtained by using various known means. Specifically, for example, it can be obtained by hydrogenating the above-mentioned various petroleum resins (aliphatic petroleum resin, alicyclic petroleum resin, aromatic petroleum resin, aliphatic-aromatic petroleum resin, hydroxyl group-containing petroleum resin) under known hydrogenation conditions.

[0042] The hydrogenation conditions include, for example, a method of heating the petroleum resin at about 200 to 350°C under a hydrogen partial pressure of about 0.2 to 30 MPa in the presence of a hydrogenation catalyst.

Also, the amount of the hydrogenation catalyst used is preferably about 0.01 to 10 parts by mass with respect to 100 parts by mass of the raw material resin.

[0043] The above hydrogenation is carried out in a state where each of the above various petroleum resins (aliphatic petroleum resin, alicyclic petroleum resin, aromatic petroleum resin, aliphatic-aromatic petroleum resin, hydroxyl group-containing petroleum resin) is melted or dissolved in a solvent.

For example, cyclohexane, n-hexane, n-heptane, decalin, tetrahydrofuran, dioxane, etc. can be used alone or in combination of two or more. The amount of the solvent used is not particularly limited, but usually the solid content is 10% by mass or more with respect to the petroleum resin, preferably in the range of 10 to 70% by mass.

[0044] In addition, the above hydrogenation conditions are described for the case where a batch system is adopted as the reaction form, but a flow system (fixed bed type, fluidized bed type, etc.) can also be adopted as the reaction form.

[0045] (Component (A)) From the viewpoints of excellent slipperiness of the fiber, chalk mark resistance, and stability of the composition, a hydrogenated aromatic petroleum resin is preferable for component (A), and from the same viewpoints, a hydrogenated C9 petroleum resin is more preferable.

[0046] (Physical properties of hydrogenated petroleum resin (A)) The physical properties of component (A) are not particularly limited. The softening point of component (A) is preferably about 80 to 180 °C, more preferably about 80 to 140 °C, and particularly preferably about 90 to 135 °C from the viewpoints of excellent slipperiness of the fiber and stability of the composition. In this specification, the softening point is a value measured by the ring and ball method (JIS K 5902).

[0047] The hydroxyl value of component (A) is preferably about 0 to 310 mgKOH / g, more preferably about 50 to 250 mgKOH / g from the viewpoint of excellent emulsion stability of the composition. In this specification, the hydroxyl value is a value measured by JIS K 0070.

[0048] The weight average molecular weight of component (A) is preferably about 500 to 3,000, more preferably about 1,100 to 2,000, in terms of excellent emulsion stability of the composition. In this specification, the weight average molecular weight is a polystyrene equivalent value determined by gel permeation chromatography (GPC).

[0049] The color tone of component (A) is preferably 100 Hazen or less, more preferably 60 Hazen or less. When the color tone of component (A) is 100 Hazen or less, the fiber product treated with the aqueous dispersion composition for fiber processing of the present invention is more suppressed in coloring (yellowing) over time. In this specification, the color tone is measured in accordance with JIS K 0071-1 for Hazen units and JIS K 0071-2 for Gardner units.

[0050] <Nonionic surfactant (B)> Component (B) is not particularly limited as long as it is a nonionic surfactant, and various known ones can be used. In the aqueous dispersion composition of the present invention, using an anionic surfactant or a cationic surfactant instead of the nonionic surfactant (B) may reduce various functions (such as water repellency and stain resistance) of the fiber processing agent, or may reduce its stability when used in combination with the fiber processing agent, which is not preferable. Component (B) may be used alone or in combination of two or more.

[0051] (Component (B) includes, for example, polyoxyethylene alkyl ethers, polyoxyethylene alkenyl ethers, polyoxyethylene alkyl phenyl ethers, polyoxy polycyclic phenyl ethers, sorbitan higher fatty acid esters, polyoxyethylene sorbitan higher fatty acid esters, polyoxyethylene higher fatty acid esters, glycerin higher fatty acid esters, block copolymers of polyalkylene oxides, etc. Specifically, polyoxyethylene lauryl ether, polyoxyethylene oleyl ether, polyoxyethylene stearyl ether, polyoxyethylene nonyl phenyl ether, polyoxyethylene octyl phenyl ether, polyoxyethylene styryl phenyl ether, sorbitan monolaurate, sorbitan trioleate, polyoxyethylene sorbitan monolaurate, polyoxyethylene monolaurate, polyoxyethylene monooleate, monoglycerin oleate, monoglycerin stearate, polyoxyethylene·polyoxypropylene·block copolymer, etc. are included.)

[0053] (Physical properties of nonionic surfactant (B)) (B) component's physical properties are not particularly limited. The HLB of (B) component is preferably 7 to 19, particularly preferably about 12 to 15, in terms of excellent emulsification stability of (A) component, stability of fiber processing agent, water repellency and stain resistance. By setting the HLB of (B) component to 7 or more, the emulsification stability of (A) component and the stability of fiber processing agent become more excellent. Also, by setting the HLB to 19 or less, the water repellency and stain resistance in the fiber processing agent become more excellent. Note that HLB is a value indicating the balance between the hydrophobicity and hydrophilicity of a surfactant, taking values from 1 to 20. The smaller the numerical value, the stronger the hydrophobicity, and the larger the numerical value, the stronger the hydrophilicity.

[0054] (B) component's usage amount is not particularly limited, but in terms of solid content conversion, it is preferably about 1 to 20 parts by mass, more preferably about 5 to 10 parts by mass, relative to 100 parts by mass of (A) component. By setting the usage amount of (B) component to 1 part by mass or more, reliable emulsification can be carried out, and the stability improves when used as a water repellent or stain resistance imparting agent. Also, by setting it to 20 parts by mass or less, it becomes difficult to impair the water repellency when used as a water repellent.

[0055] <Surfactant (C)> For the purpose of improving the dispersibility of the above composition of the present invention, as long as the effects of the present invention are not impaired, a surfactant (C) other than (B) component (hereinafter also referred to as (C) component) may be included as needed.

Specifically, high molecular weight emulsifiers obtained by polymerizing monomers, low molecular weight anionic emulsifiers, low molecular weight cationic emulsifiers, etc. can be mentioned. These can be used alone or in combination of two or more. Among these, low molecular weight anionic emulsifiers are preferred from the viewpoint of excellent emulsifying properties.

The weight average molecular weight referred to here is the polyethylene oxide conversion value determined by gel permeation chromatography (GPC).

[0060] Examples of the reactive emulsifier other than the high molecular weight emulsifier include those having a hydrophilic group such as a sulfonic acid group or a carboxyl group and a hydrophobic group such as an alkyl group or a phenyl group, and having a carbon-carbon double bond in the molecule.

[0064] From the viewpoint of excellent emulsifying properties, the amount of component (C) used is preferably about 1 to 10 parts by mass, more preferably about 2 to 8 parts by mass, in terms of solid content, per 100 parts by mass of component (A).

[0067] The above emulsification method is not particularly limited, and known emulsification methods such as high-pressure emulsification method and phase inversion emulsification method can be adopted.

[0068] The above high-pressure emulsification method is a method in which component (A) is in a liquid state, the above emulsifier and water are preliminarily mixed, finely emulsified using a high-pressure emulsifier, and then the solvent is removed if necessary. The method of making component (A) in a liquid state may be by heating only, heating after dissolving in a solvent, or heating after mixing with a non-volatile substance such as a plasticizer. Examples of the solvent include organic solvents capable of dissolving component (A) such as toluene, xylene, methylcyclohexane, and ethyl acetate.

[0069] The above phase inversion emulsification method is a method in which component (A) is heated and melted, and then while stirring, a surfactant and water are added to first form a W / O emulsion, and then it is phase-inverted to an O / W emulsion by adding water or changing the temperature, etc.

By setting the above-mentioned amount to 1% by mass or more, the slipperiness of the fiber becomes more excellent. Further, by setting the above-mentioned amount to 20% by mass or less, the chalking mark resistance of the fiber becomes more excellent, and furthermore, when a water repellent or a stain resistance imparting agent is used, the functions of water repellency and stain resistance are more maintained, which is preferable.

Examples of chemical fibers include inorganic fibers such as rock fiber, metal fiber, graphite, silica, and titanate; regenerated cellulose fibers such as rayon, cupra, viscose, polynosic, and purified cellulose fiber; melt-spun cellulose fiber; protein fibers such as milk protein and soybean protein; regenerated and semi-synthetic fibers such as regenerated silk and alginate fiber; and synthetic fibers such as polyamide fiber, polyester fiber, cation-dyeable polyester fiber, polyvinyl fiber, polyacrylic alcohol fiber, polyurethane fiber, acrylic fiber, polyethylene fiber, polyvinylidene fiber, and polystyrene fiber. Further, two or more of these fibers may be combined (blended, mixed, interwoven, interlaced, etc.).

[0081] Examples of the polyester fiber include fibers composed of polymers condensed by a reaction that forms an ester bond, such as polyethylene terephthalate (PET) fiber, polylactic acid (PLA) fiber, polytrimethylene terephthalate (PTT) fiber, polybutylene terephthalate (PBT) fiber, polypropylene terephthalate (PPT) fiber, polyethylene naphthalate (PEN) fiber, and polyarylate fiber. Examples of the fiber to be compounded with the polyester fiber include synthetic fibers and natural fibers such as cellulose fiber, polyamide fiber, and polyurethane fiber.

[0082] The polyamide fiber means a fiber that essentially contains polyamide and may be compounded. Examples thereof include nylon 6, nylon 66, nylon 610, nylon 11, nylon 4, nylon 7, and aromatic nylon (aramid). Polyamide is usually obtained by condensation through a reaction that forms an amide bond.

[0083] Examples of the form of the fiber include forms such as woven fabric, knitted fabric, cloth, filament, cheese, skein, and non-woven fabric.

[0084] The aqueous dispersion composition for fiber processing of the present invention is preferably used for polyester fiber, polyamide fiber, and cotton. Particularly, polyester fiber and cotton are preferred.

[0085] <Fiber processing> The method for processing the above-mentioned fiber using the aqueous dispersion composition for fiber processing of the present invention and the above-mentioned fiber processing agent is not particularly limited. Examples thereof include processing methods such as dipping, spraying, and coating, or processing methods by a cleaning method. Further, after the aqueous dispersion composition for fiber processing and the above-mentioned fiber processing agent are adhered to the fiber, it is preferable to dry to remove water.

[0086] In the above processing, the total adhesion amount of the aqueous dispersion composition for fiber processing and the above fiber processing agent to the fiber can be appropriately adjusted according to the degree of required functions. However, it is preferably adjusted to be 0.1 to 10% by mass in terms of solid content with respect to the fiber, and more preferably adjusted to be 0.5 to 2% by mass. If the above total adhesion amount is less than 0.1% by mass, the effect is difficult to appear, and if it exceeds 10% by mass, the cost-effectiveness becomes low.

[0087] After processing the fiber using the aqueous dispersion composition for fiber processing of the present invention and the above fiber processing agent, it is preferably heat-treated as appropriate. The temperature conditions are not particularly limited, but are usually about 110 to 180 °C.

[0088] Examples of the use of the fiber subjected to the above processing include objects to which water repellency and stain resistance are imparted, such as clothing for outerwear, uniforms, sports, etc.; hygiene materials such as masks, gauze, paper diapers, etc.; vehicle interior materials for automobiles, airplanes, railways, ships, etc.; bedding such as futons, mattresses, sheets, pillows, covers, blankets, towel quilts, etc.; interiors such as curtains, blinds, sofas, chairs, cushions, wallpapers, carpets, tablecloths, cushions, fusuma, etc.; industrial materials such as notebooks, blackouts, construction sheets, tents, filters, etc.

[0089] Examples of the use of the fiber subjected to the above processing include clothing and bedding called outerwear, specifically, outer fabrics for down, coats, blousons, windbreakers, blouses, dress shirts, skirts, slacks, gloves, hats, outer fabrics for futons, futon drying covers, curtains or tents, etc. It is preferably used for fiber product applications such as clothing applications and non-clothing applications because it has various functions such as excellent water repellency, washing durability, and stain resistance.
