[0004] The present application provides a process for improving the dry and wet rubbing color fastness of knitted fabrics, which adopts the following technical solution: A process for improving the dry and wet rubbing color fastness of knitted fabrics, comprising the following steps: Cleaning: dissolving the detergent in water, stirring and mixing evenly to obtain a washing liquid, then immersing the textiles evenly in the washing liquid and stirring, and then rinsing with clean water to obtain cleaned textiles; the raw materials of the detergent include the following components in parts by weight: 10 to 30 parts of a builder, 5 to 15 parts of a stabilizer, 3 to 10 parts of a dispersant, 20 to 40 parts of a surfactant, and 15 to 25 parts of water; Color fixing treatment: dissolving the dry and wet friction fastness improver in water, stirring and mixing evenly to obtain a improving liquid, and evenly immersing the cleaned textile in the improving liquid, soaking, and dehydrating to obtain improved textiles; the raw materials of the dry and wet friction fastness improver include the following components in parts by weight: 50-70 parts of waterborne polyurethane, 10-20 parts of coupling agent, 5-15 parts of styrene-acrylic emulsion, 3-5 parts of dispersant, and 10-20 parts of water; Drying: The textiles are lifted and dried; Ironing: Iron the lifted textiles to obtain finished textiles.

[0005] By adopting the above technical scheme, the floating color in the textile is first washed out with a detergent to reduce the residual floating color on the surface of the textile, and then the textile is fixed with a dry and wet friction fastness improver. The dispersant makes the styrene acrylic emulsion evenly dispersed in the improving liquid, and the coupling agent makes the water-based polyurethane and styrene acrylic emulsion form a soft film covering the dye on the surface of the textile, so that the dye is not easy to fall off when the textile is rubbed, thereby improving the dry and wet friction color fastness of the textile.

[0006] In a specific embodiment, the builder comprises a mixture of sodium carbonate and sodium silicate.

[0007] By adopting the technical scheme and utilizing the composite detergent composed of sodium carbonate and sodium silicate, the cleaning effect on textiles is improved.

[0014] In a specific embodiment, the raw materials of the wet and dry friction fastness improving agent further include 5 to 10 parts by weight of an organic silicon softener.

[0015] By adopting the above technical solution, the addition of silicone softener can penetrate into the interior of textile fibers, making the textiles softer and improving the feel and wearing comfort of the textiles.

[0016] In a specific embodiment, in the cleaning step, the weight ratio of the detergent in the washing liquid is 0.5%-1.5%, and the bath ratio is 1:10.

[0017] By adopting the above technical solution, the amount of detergent used is further limited, thereby improving the cleaning effect on textiles.

[0018] In a specific embodiment, in the color fixing step, the weight ratio of the dry and wet friction fastness enhancer in the enhancing liquid is 4.5%-5.5%, and the bath ratio is 1:20.

[0019] By adopting the above technical solution, the dosage of the dry and wet friction fastness improving agent is further limited, thereby improving the effect of color fixing treatment on textiles.

[0020] In summary, the present application includes at least one of the following beneficial technical effects: 1. In the present application, the floating color in the textile is first washed out with a detergent to reduce the residual floating color on the surface of the textile, and then the textile is fixed with a dry and wet friction fastness enhancer.

[0044] Comparative Example Comparative Example 1 Comparative Example 1 provides a process for improving the dry and wet rubbing color fastness of knitted fabrics, comprising the following steps: Cleaning: dissolve the detergent in Preparation Example 1 in water, stir and mix evenly to obtain a washing liquid, and then evenly immerse the textile in the washing liquid at room temperature and stir and wash for 12 minutes, the bath ratio is 1:10, and rinse with clean water after washing to obtain a cleaned textile; wherein the weight ratio of the detergent in the washing liquid is 1%; Color fixing treatment: dissolve water-based polyurethane in water, stir and mix evenly to obtain a lifting liquid, and at room temperature, evenly immerse the cleaned textile in the lifting liquid for 1 hour, with a bath ratio of 1:20, and dehydrate to obtain a lifted textile; wherein the weight ratio of the water-based polyurethane in the lifting liquid is 5%; Drying: Dry the textiles at 65℃; Ironing: Iron the lifted textiles to obtain finished textiles.

[0045] Performance testing Color fastness test: The lifting process in Example 1 was used to treat pure cotton, wool, cashmere, lyocell / silk, cotton / lyocell, and wool / cashmere, and the color fastness of dry rubbing and wet rubbing before and after treatment were tested, respectively. The registration is divided into 5 levels, and the higher the level, the better the color fastness of the textile. Then, taking wool / cashmere as an example, the treatment effect of the lifting processes in other embodiments and comparative examples on wool / cashmere was tested.

[0046] Table 1 Performance test results of textiles in Example 1 Table 2 Performance test results of wool / cashmere Combined with Table 1, it can be seen that the process for improving the dry and wet friction color fastness of knitted fabrics in the present application can have a good color fixing effect on textiles such as pure cotton, wool, cashmere, lyocell / mulberry silk, cotton / lyocell, wool / cashmere, etc., and improve their dry and wet friction color fastness, among which the treatment effect on wool and cashmere is the best.

[0047] Combining Table 2, Examples 1-3 and Comparative Example 1, the treatment effect of wool / cashmere in Examples 1-3 is better. It can be seen that in the treatment process of the present application, the floating color in the textile is first washed out with a detergent to reduce the floating color residue on the surface of the textile, and then the textile is fixed with a dry and wet friction fastness enhancer. The dispersant makes the styrene acrylic emulsion evenly dispersed in the enhancing liquid, and the coupling agent makes the aqueous polyurethane and styrene acrylic emulsion form a soft film covering the dye on the surface of the textile, so that the dye is not easy to fall off when the textile is rubbed, thereby improving the dry and wet friction color fastness of the wool / cashmere.

[0048] Combining Table 2, Example 2, Example 4 and Example 5, the treatment effect of wool / cashmere in Example 2 is the best. It can be seen that when preparing the detergent, the builder is preferably a mixture of sodium carbonate and sodium silicate, which can improve the cleaning effect on the textiles and facilitate the color fixation treatment thereof, thereby improving the dry and wet friction color fastness of the wool / cashmere.

[0049] Combining Table 2, Example 2, Example 6 and Example 7, the treatment effect of wool / cashmere in Example 2 is the best. It can be seen that when preparing the detergent, the surfactant is preferably a mixture of fatty alcohol polyoxyethylene ether and sodium lauryl sulfate, which can improve the cleaning effect on textiles, thereby facilitating the color fixation treatment thereof, thereby improving the dry and wet friction color fastness of wool / cashmere.

[0050] Combining Table 2, Example 2, Example 8 and Example 9, the treatment effect of wool / cashmere in Example 8 is the best, which shows that when preparing the dry and wet friction fastness improving agent, the ratio of raw materials in Preparation Example 9 is the best.

[0051] Combining Table 2, Example 8 and Example 10, it can be seen that when preparing the dry and wet friction fastness improving agent, adding the silicone softener to the raw materials can penetrate into the interior of the textile fiber, making the textile softer, improving the hand feel and wearing comfort, and at the same time having little effect on the dry and wet friction color fastness of wool / cashmere.

[0052] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
