However, during the process of getting along with pets, especially during the period of pet hair loss in spring and autumn, the owner hugs the beloved pet one second, and the next second, the clothes are adhered to the pet hair that is difficult to pat off. It is really a sweet burden for the pet owner. Therefore, consumers have a strong demand for anti-static wool clothes.

[0003] As one of the highlights of the textile industry's innovation technology development, the concept of anti-static wool fabric has been widely anticipated by the market since it was proposed. At present, most of the research on anti-static wool fabrics focuses on solving the problem of static wool adhesion of polyester chemical fiber fabrics. The adhesion of polyester fabrics to wool fibers is mainly due to the static electricity adsorption caused by fabric friction. The anti-static finishing can effectively improve the problem of static wool adhesion of polyester fabrics. However, in practical applications, chemical fiber fabrics are less used for home clothes. The common fabrics for home clothes are cellulose fiber types, such as cotton, viscose, lyocell, etc. The surface of cellulose fibers has rich polar groups. The adhesion of cellulose-based fabrics to protein hair is mainly related to their loose spinning structure. At present, there are some methods for manufacturing anti-static wool fabrics.

[0028] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] The surface of cellulose fibers has abundant polar groups, and the loose spinning structure of cellulose-based fabrics is the key factor for their adsorption of protein hairs. The inventors of this application found that using a high-molecular crosslinking agent to treat the cellulose-based fabric to prevent hair sticking makes the overall structure of the cellulose-based fabric become tight, thereby endowing the fabric with the property of preventing hair sticking. However, the hand feeling of the fabric is affected. Continuing to increase the dosage of the high-molecular crosslinking agent improves the anti-hair-sticking performance of the fabric, but its hand feeling becomes significantly hard, which further leads to a significant deterioration in the wearing feeling of the home clothes made of this fabric. Further exploration found that adding a small-molecular crosslinking agent on the basis of a small amount of high-molecular crosslinking agent, the small-molecular crosslinking agent can cooperate with the high-molecular crosslinking agent. Through chemical bonding or physical interpenetrating network structure action, it assists the high-molecular crosslinking agent to form a physical or chemical bonding action with the cellulose-based fabric, thereby improving the anti-hair-sticking performance of the cellulose-based fabric. The inventors continued to explore and found that on the premise of maintaining a comparable anti-hair-sticking performance, appropriately reducing the dosage of the high-molecular crosslinking agent and adding a small-molecular crosslinking agent can, to a certain extent, improve the problem of serious hardening of the hand feeling of the fabric caused by a high dosage of the high-molecular crosslinking agent.

[0030] Based on this, the present invention provides an anti-hair-sticking textile auxiliary for cellulose-based fabrics. Calculated by weight parts, it includes 0.3 to 10 parts of a high-molecular crosslinking agent, 0.1 to 20 parts of a small-molecular crosslinking agent, 0.1 to 20 parts of a hand feeling modifier, and 50 to 99.5 parts of deionized water; the above-mentioned high-molecular crosslinking agent is a polymer containing one or more groups of carboxyl, amide, hydroxyl, and amino in the molecule; the above-mentioned small-molecular crosslinking agent is a compound containing one or more groups of isocyanate, silane oxy group, and titanate oxy group in the molecule; wherein the above-mentioned high-molecular crosslinking agent and the above-mentioned small-molecular crosslinking agent cooperate and bond through chemical bonding or physical interpenetrating network structure action, and can form a physical or chemical bonding action with the cellulose-based fabric, reducing the height of hair tuft protrusions on the surface of the cellulose-based fabric.

[0031] The principle that the above-mentioned high-molecular crosslinking agent and small-molecular crosslinking agent can form a chemical bonding action with the cellulose-based fabric is that after the high-molecular crosslinking agent in the anti-hair-sticking textile auxiliary is dried and cured, it can form a polymer with a continuous three-dimensional network crosslinking structure by itself, and form a chemical bonding action with the cellulose-based fabric through intermolecular forces, hydrogen bonds, ionic bonds or chemical bonds; the small-molecular crosslinking agent in the anti-hair-sticking textile auxiliary can react with the cellulose-based fabric, and can also chemically bond with the high-molecular crosslinking agent containing active groups (carboxyl, amide, hydroxyl, amino) or form a physical interpenetrating network structure, forming a chemical bonding action with the cellulose-based fabric.

[0042] The present invention also provides the application of the above-mentioned anti-static textile auxiliary, which is used as a functional emulsion auxiliary in the textile finishing process.

[0043] According to another aspect of the present invention, a method for anti-static finishing of cellulose-based fabrics using the above-mentioned anti-static textile auxiliary is provided, which comprises the following steps:

[0044] S1. Use the above-mentioned anti-static textile auxiliary to perform anti-static treatment on the cellulose-based fabric to be finished;

[0045] S2. Dry the cellulose-based fabric after the above-mentioned anti-static treatment to obtain an anti-static cellulose-based fabric.

[0046] In some embodiments, the cellulose-based fabric to be finished can be a cellulose-based fabric after pretreatment, dyeing and fixing, etc., and the present application does not limit this. In some embodiments, in step S1, the cellulose-based fabric includes any one of cotton fabrics, sanded cotton fabrics, lyocell fabrics, and viscose fabrics.

[0047] It should be noted that the present application does not limit the method of "anti-static treatment" in step S1. In some embodiments, step S1 is specifically: impregnating and rolling the cellulose-based fabric to be finished with the above anti-static textile auxiliary agent for anti-static treatment. Among them, the present application does not limit the process requirements of impregnating and rolling. For example, the process requirements can be: the duration of impregnating and rolling the cellulose-based fabric to be finished with the above anti-static textile auxiliary agent reaches a preset duration; and / or at least one index of the cellulose-based fabric meets the set requirements. The indexes can include but are not limited to softness, penetration degree, liquid-carrying rate, and so on. In addition, other methods can also be used for anti-static treatment, such as repeatedly spraying the above anti-static textile auxiliary agent on the cellulose-based fabric, or brushing the above anti-static textile auxiliary agent on the cellulose-based fabric, and so on.

[0048] In some embodiments, in step S1, the time of the above anti-static treatment is not less than 3 s, and the liquid-carrying rate of the cellulose-based fabric after the anti-static treatment is 50% - 150%. In actual applications, appropriately extending the treatment time according to the anti-static treatment method is also within the protection scope of the present invention.

[0049] In some embodiments, the drying method in step S2 is a pressure-combined temperature integrated drying method, such as any one of hot pressing, calendering, and ironing. Specifically, it can be selected according to the properties of the cellulose-based fabric and the specific situation of the drying equipment. In some embodiments, the drying temperature can be 100°C - 150°C, the drying pressure is 0.03 MPa - 0.6 MPa, and the drying time is not less than 30 s.

[0050] The "pressure-combined temperature integrated drying method" described in the present invention means drying under a certain temperature and pressure. On the one hand, this drying method can dry the cellulose-based fabric after the above anti-static treatment. On the other hand, with the drying pressure of this drying method, the height of the fiber tufts on the surface of the cellulose-based fabric can be further reduced.

[0051] The anti-static finishing method of the cellulose-based fabric provided by the present invention uses the chemical bonding or physical interpenetrating network structure of the polymer cross-linking agent and the small molecule cross-linking agent to synergistically bond, and can form a physical or chemical bonding effect with the cellulose-based fabric, thereby reducing the height of the disordered fiber tufts on the surface of the cellulose-based fabric. In addition, the drying pressure of the pressure-combined temperature integrated drying method can also further reduce the height of the fiber tufts on the surface of the cellulose-based fabric, solving the problem of fabric sticking to hair. On the other hand, the addition of the small molecule cross-linking agent can, to a certain extent, improve the problem of severe stiffness of the fabric feel caused by a high dosage of the polymer cross-linking agent, and the softening effect of the feel modifier can fully balance the feel problem of the cellulose-based fabric.

[0052] The present invention also provides an anti-static cellulose-based fabric, which is obtained by treating with the above anti-static textile auxiliary or the anti-static finishing method of the above cellulose-based fabric.

[0053] It should be noted that the reagents used in the examples and control examples of this application can be prepared in the laboratory by oneself or obtained through commercial purchase. When testing the anti-static performance of the cellulose-based fabric in this application, the test environment and the hair used for testing are not limited.

[0091] 1) The anti-static textile auxiliary agent, calculated by weight, includes a high-molecular cross-linking agent (0.5 parts of chitosan chloride with a molecular weight of 100,000), a low-molecular cross-linking agent (1 part of bis(dioctyloxyphosphate) ethylene titanate coupling agent HY311W), a hand feel modifier (0.5 part of quaternary ammonium fatty amide soft sheet TY3-24A), and 98 parts of deionized water.

[0092] 2) The preparation method of the anti-static textile auxiliary agent in this example is the same as that in Example 1.

[0093] 3) Anti-static treatment of the cellulose-based fabric: Immerse the napped cotton fabric to be finished in the anti-static textile auxiliary agent for 10 s, take out the napped cotton fabric, and use a calender to squeeze out the excess anti-static textile auxiliary agent on the fabric so that the liquor pickup of the fabric is 100%, calender and dry the napped cotton fabric, the drying temperature is 100 °C, the drying time is 60 s, and the drying pressure is 0.6 MPa to obtain the anti-static napped cotton fabric.

[0094] 4) The anti-static test and hand feel test are the same as those in Example 1.

[0098] The anti-static wool textile auxiliary of Comparative Example 1 only contains 100 parts of deionized water. Comparing Example 1 and Comparative Example 1, it is found that Figure 1 and Figure 3 it can be seen that the weaving structure of the anti-static wool cellulose-based fabric prepared in Example 1 is relatively tight compared with that of Comparative Example 1; from Figure 2 and Figure 4 it can be seen that the anti-static wool performance of the anti-static wool cellulose-based fabric prepared in Example 1 is better than that of Comparative Example 1; it can be seen from Table 1 that the anti-static wool cellulose-based fabric prepared in Example 1 has excellent anti-static wool performance and a soft hand feeling, and both are significantly better than Comparative Example 1.

[0099] The anti-static wool textile auxiliaries of Comparative Examples 2 and 3 are prepared by adding 0.5 part and 1 part of high molecular cross-linking agent on the basis of Comparative Example 1. Comparing Comparative Examples 1, 2, and 3, it can be seen that the anti-static wool performance of the anti-static wool cellulose-based fabric prepared in Comparative Example 3 > Comparative Example 2 > Comparative Example 1, and the hand feeling of the anti-static wool cellulose-based fabric prepared in Comparative Example 3 < Comparative Example 2 < Comparative Example 1. This shows that increasing the weight fraction of the high molecular cross-linking agent significantly improves the anti-static wool performance of the cellulose-based fabric, but the hand feeling of the fabric becomes significantly worse.

[0100] The anti-static wool textile auxiliaries of Comparative Examples 4 and 5 are prepared by adding 0.2 part of small molecule cross-linking agent and 0.3 part of hand feeling modifier on the basis of Comparative Example 2. Comparing Comparative Example 4 with Comparative Example 2, the anti-static wool performance of the anti-static wool cellulose-based fabric prepared in Comparative Example 4 is better than that of Comparative Example 2, and the hand feeling of the fabric is the same as that of Comparative Example 2. This shows that the small molecule cross-linking agent added to the anti-static wool textile auxiliary can cooperate with the high molecular cross-linking agent to bond, and through chemical bonding or physical interpenetrating network structure action, assist the high molecular cross-linking agent to form physical or chemical bonding with the fabric, further improving the anti-static wool performance of the cellulose-based fabric. In addition, the addition of the small molecule cross-linking agent and the maintenance of the dosage of the high molecular cross-linking agent maintain the hand feeling of the fabric.

[0101] Comparing Comparative Example 5 with Comparative Example 2, the hand feeling of the anti-static wool cellulose-based fabric prepared in Comparative Example 5 is better than that of Comparative Example 2, and its anti-static wool performance is worse than that of Comparative Example 2. This shows that adding a hand feeling modifier to the anti-static wool textile auxiliary can significantly improve the hand feeling of the cellulose-based fabric, while the hand feeling modifier itself has slight static electricity adhesion, which will cause the anti-static wool performance of the fabric to decline. Comparing Example 1 and Comparative Example 5, it can be seen that the small molecule cross-linking agent added in Example 1 can cooperate with the high molecular cross-linking agent and the hand feeling modifier, which can not only solve the static electricity adhesion problem of the cellulose-based fabric itself, but also solve the static electricity adhesion problem of the fabric caused by the slight static electricity adhesion of the hand feeling modifier itself, making the prepared anti-static wool cellulose-based fabric have excellent anti-static wool performance and a soft hand feeling.

[0102] Combining Example 1 and Comparative Examples 1 to 5, it can be seen that the anti-static hair cellulose-based fabrics treated with the anti-static hair textile auxiliaries provided in Comparative Examples 1 to 5 cannot simultaneously have excellent anti-static hair performance and a soft hand feeling, and none of them reach the level of Example 1.

[0103] In Examples 1 to 5, the anti-static hair textile auxiliaries provided in the present application were used to perform anti-static hair finishing on different types of cellulose-based fabrics. After anti-static hair testing and hand feeling testing, the different types of anti-static hair cellulose-based fabrics prepared in the examples of the present application all have excellent anti-static hair performance and a soft hand feeling. This shows that the anti-static hair cellulose-based fabrics obtained by using the anti-static hair textile auxiliaries provided in the present application and the anti-static hair finishing method of cellulose-based fabrics using the anti-static hair textile auxiliaries have excellent anti-static hair performance and a soft hand feeling.

[0104] It is easy for those skilled in the art to understand that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
