Problems solved by technology

Among them, the chemical method is the most obvious anti-wrinkle method at present. The 2D resin finishing agent is the most commonly used one in the N-methylolamide resin non-ironing finishing agent. Its anti-wrinkle finishing effect is good, but it seriously damages the strength of the fabric. A large amount of formaldehyde is released, which is harmful to human health; although BTCA is an excellent formaldehyde-free anti-wrinkle finishing agent, it can endow silk fabric with better wrinkle elasticity and protect its original characteristics such as strength and drape, but due to BTCA is expensive and its promotion is limited

Embodiment 1

[0013] Example 1: 12g of methyl methacrylate oligomer, 6g of formic acid, 9g of sodium bicarbonate, 1g of silicone softener JY-102 and 72g of water were prepared into an anti-wrinkle finishing agent; at a bath ratio of 1:25, at a temperature of 20°C Under the following conditions, the silk fabric was dipped and rolled twice in the finishing solution containing anti-wrinkle finishing agent, and the excess rate was 90%; the silk fabric after padding was pre-baked at 80°C for 3 minutes, and then baked at 150°C for 1 minute, followed by Washing with hot water at 40-50° C., washing with water at 20-25° C., and drying at 70-80° C. to obtain a finished silk fabric. Cut the silk fabric into samples and soak in 0.3% Pingping O solution for 5 minutes, take it out, remove the water, measure the wrinkle recovery angle in wet state according to the vertical method in GB / T3819-1997, and the wrinkle recovery angle in dry state and wet state The crease recovery angles are 277° and 264° respec...

Embodiment 2

[0014] Example 2: 14g of methyl methacrylate oligomer, 5g of formic acid, 10g of sodium bicarbonate, 2g of silicone softener JY-102 and 69g of water are prepared into an anti-wrinkle finishing agent; at a bath ratio of 1:30, the temperature is 25°C Under the following conditions, the silk fabric was dipped and rolled twice in the finishing solution containing anti-wrinkle finishing agent, and the excess rate was 88%; the silk fabric after padding was pre-baked at 75°C for 5 minutes, and then baked at 140°C for 2 minutes, followed by Washing with hot water at 40-50° C., washing with water at 20-25° C., and drying at 70-80° C. to obtain a finished silk fabric. Cut the silk fabric into samples and soak in 0.3% Pingping O solution for 5 minutes, take it out, remove the water, measure the wrinkle recovery angle in wet state according to the vertical method in GB / T3819-1997, and the wrinkle recovery angle in dry state and wet state The crease recovery angles are 275° and 263° respec...

Embodiment 3

[0015] Example 3: 15g of methyl methacrylate oligomer, 6g of formic acid, 8g of sodium bicarbonate, 1g of silicone softener JY-102 and 70g of water are prepared into an anti-wrinkle finishing agent; at a bath ratio of 1:30, the temperature is 30°C Under the following conditions, the silk fabric was dipped and rolled twice in the finishing solution containing anti-wrinkle finishing agent, and the passover rate was 85%; the silk fabric after padding was pre-baked at 70°C for 3 minutes, and then baked at 150°C for 1 minute, followed by Washing with hot water at 40-50° C., washing with water at 20-25° C., and drying at 70-80° C. to obtain a finished silk fabric. Cut the silk fabric into samples and soak in 0.3% Pingping O solution for 5 minutes, take it out, remove the water, measure the wrinkle recovery angle in wet state according to the vertical method in GB / T3819-1997, and the wrinkle recovery angle in dry state and wet state The crease recovery angles are 273° and 264° respec...

Abstract

The invention discloses an anti-wrinkle finishing process of a silk fabric, which relates to the technical field of anti-wrinkle finishing of fabrics. The anti-wrinkle finishing process comprises the following steps of preparing an anti-wrinkle finishing agent from the components of olefin acid oligomer, formic acid, a catalyst, an organic silicone softening agent and water; under the conditions that the bath ratio is 1:(25-30) and the temperature is 20-30 DEG C, carrying out immersion and rolling for twice on the silk fabric in finishing liquor containing the anti-wrinkle finishing agent with the take-up rate being 85%-90%; prebaking the immersed and rolled silk fabric for 3-5 minutes, then baking the fabric for 1-2 minutes at the temperature of 140-150 DEG C, washing by hot water at the temperature of 40-50 DEG C and water at the temperature of 20-25 DEG C, drying at the temperature of 70-80 DEG C to obtain the finished silk fabric. The anti-wrinkle finishing process disclosed by the invention has the advantages that the raw materials of the anti-wrinkle finishing agent are low in price, do not contain formaldehyde, and has economic and environment-friendly effects; the anti-wrinkle finishing process is simple and easy to operate; the finished silk fabric has good anti-wrinkle recovery performance, a high retention rate and good anti-wrinkle performance.

Description

Technical field: [0001] The invention relates to the technical field of anti-wrinkle finishing of fabrics, in particular to an anti-wrinkle finishing process of silk fabrics. Background technique: [0002] Silk fabric has the characteristics of soft luster, smooth touch, moisture absorption and breathability, and is pure and natural. The clothing is not only beautiful and comfortable, but also has multiple health care functions. However, its poor resilience and easy wrinkling affect its use effect. At present, the methods for improving the anti-wrinkle performance of silk fabrics include: physical methods, such as changing the structure of the fabric, changing the weaving method, etc.; chemical methods, such as 2D resin, BTCA, etc. as finishing agents for anti-wrinkle finishing; physical and chemical methods, such as sand washing and low-temperature plasma body treatment technology. Among them, the chemical method is the most obvious method of anti-wrinkle effect at present...
