Problems solved by technology

However, due to the poor dimensional stability of silk fabrics, it is easy to wrinkle and shrink during wearing and washing. It is not suitable for machine washing and has no non-ironing performance. Therefore, many years ago, people began to use physical methods, such as changing Silk fabric structure; chemical methods, such as user 2D resin, glyoxal, etc., as finishing agents for anti-wrinkle finishing. The above-mentioned method has good anti-wrinkle finishing effect, but it seriously damages the strength of the fabric and releases a large amount of formaldehyde, which is not good for human health.

Embodiment 1

[0012] Put the silk fabric in an irradiation tube, add acrylic acid solution with a concentration of 3%, vacuumize and replace with nitrogen three times, seal it, and place it in a Co-60 source for irradiation. The irradiation dose is 4.5kGy, and the irradiation time is 15h. The temperature is 16°C, after the irradiation, take out the silk fabric and wash it with water; place the grafted silk fabric at 20-30°C with a weight fraction of 0.5% fatty alcohol polyoxyethylene ether and a weight fraction of 2% silicone resin Padding in the finishing solution, the excess rate is 100%, dried at 40-50°C for 5 minutes, then baked at 120°C for 3 minutes, washed with water, and dried to obtain the modified silk fabric. According to the method specified in GB / T3819-83, the dry wrinkle recovery angle is tested as 243° (quick bounce) and 261° (slow bounce).

Embodiment 2

[0014] Put the silk fabric in the irradiation tube, add acrylic acid solution with a concentration of 5%, vacuumize and replace it with nitrogen three times, seal it, and place it in a Co-60 source for irradiation. The irradiation dose is 8kGy, the irradiation time is 24h, and the temperature at 25°C, after the irradiation, take out the silk fabric and wash it with water; place the grafted silk fabric at 20-30°C in an environment containing 2.5% by weight of fatty alcohol polyoxyethylene ether and 1% by weight of silicone resin. Padding in the finishing solution, the excess rate is 100%, drying at 40-50°C for 3 minutes, then baking at 130°C for 5 minutes, washing with water, and drying to obtain the modified silk fabric. According to the method specified in GB / T3819-83, the dry wrinkle recovery angle is tested as 255° (quick bounce) and 274° (slow bounce).

Embodiment 3

[0016] Put the silk fabric in the irradiation tube, add acrylic acid solution with a concentration of 4%, vacuumize and replace it with nitrogen three times, seal it, and place it in a Co-60 source for irradiation. The irradiation dose is 6kGy, the irradiation time is 20h, and the temperature at 20°C, take out the silk fabric after the irradiation, and wash it with water; place the grafted silk fabric at 20-30°C with a weight fraction of 1.5% fatty alcohol polyoxyethylene ether, a weight fraction of 1% silicone resin and Padding in the finishing solution with a weight fraction of 0.3% sodium hypophosphite, the excess rate is 100%, drying at 40-50°C for 3 minutes, then baking at 130°C for 5 minutes, then washing with water, and drying to obtain the modified silk fabric . According to the method specified in GB / T3819-83, the dry wrinkle recovery angle is tested as 256° (quick bounce) and 283° (slow bounce).

Abstract

The present invention discloses a production method for improving wrinkle resistance of a silk fabric. The production method comprises: placing a silk fabric into an irradiation rube, adding an acrylic acid solution, carrying out vacuum-pumping nitrogen-filling replacement three times, sealing, placing in a Co-60 source to irradiate, taking the silk fabric out after completing irradiation, and carrying out water washing; placing the grafted silk fabric into a finishing solution containing fatty alcohol polyoxyethylene ether and an organosilicon resin at a temperature of 20-30 DEG C to pad, wherein a liquor retention rate is 100%; and drying for 3-5 min at a temperature of 40-50 DEG C, baking for 3-5 min at a temperature of 120-130 DEG C, carrying out water washing, and drying to obtain the modified silk fabric. With the method, the inherent nature characteristic of the silk fabric can not be damaged, and the dry crease recovery angle can be effectively increased with baking by using the finishing solution, such that wrinkle resistance of the fabric can be improved, and little hand feeling and little whiteness of the fabric are affected.

Description

Technical field: [0001] The invention relates to the technical field of modification of silk fabrics, in particular to a production method for improving the wrinkle resistance of silk fabrics. Background technique: [0002] Silk fabric has excellent characteristics such as lightness, smooth feel, good luster, good moisture absorption and breathability, elegant appearance, and health care functions, and has become one of the favorite clothing fabrics for most people. However, due to the poor dimensional stability of silk fabrics, it is easy to wrinkle and shrink during wearing and washing. It is not suitable for machine washing and has no non-ironing performance. Therefore, many years ago, people began to use physical methods, such as changing Silk fabric structure; chemical methods, such as user 2D resin, glyoxal, etc., as finishing agents for anti-wrinkle finishing. The above-mentioned method has good anti-wrinkle finishing effect, but it seriously damages the strength of t...
