Example Embodiment

[0015] Example 1

[0016] 120g of FAP, 20g of sodium carbonate, and 2g of sodium hydroxide were added to 1L of water, heated to make FAP partially hydrolyzed and completely dissolved, as a finishing liquid. Dip the pure cotton fabric into the finishing solution, fully immerse it, dehydrate to 70% of the liquid rate, dry at 80℃×1min, then bake at 140℃ for 3min, wash with water, neutralize with HAc, and pad the silicone The softener is dried at 80°C to obtain the finished product.

Example Embodiment

[0017] Example 2

[0018] 100g of FAP and 20g of sodium carbonate were added to 1L of water, heated to make FAP partially hydrolyzed and completely dissolved, as a finishing liquid. The pure cotton fabric is padding and finishing liquid, with a liquid rate of 60%, then steamed for 2 minutes at 120°C and humidity 60%, washed with water, neutralized with HAc, padding with silicone softener, and dried at 80°C. Finished product.

Abstract

The invention relates to a high-strength-retention non-ironing finishing method for pure cotton textiles. The method comprises the steps: padding the pure cotton textiles with finishing liquid at a liquid entrainment rate of 40% to 80%, then, carrying out baking, and then, carrying out neutralization washing and softening, thereby obtaining the pure cotton textiles, wherein a method for preparingthe finishing liquid comprises the steps of adding 1,3,5-triacryl hexahydro-1,3,5-triazinyl FAP and alkali, which are in a mass ratio of (50 to 160): (2 to 50), into water, heating the temperature ofthe mixture to 80 DEG C to 95 DEG C to subject the FAP to a hydrolysis reaction until the FAP is completely dissolved. According to the method, the problem of poor water solubility is overcome, and the disadvantage of ammonia water modification is also avoided; the cotton textiles are finished with the hydrolyzed FAP, the non-ironing anticrease effect is good; crosslinking is performed under alkaline conditions, so that the problem of high-temperature acid degradation of cellulose is absent, and the strength retention is high.

Description

technical field [0001] The invention belongs to the field of non-ironing finishing, in particular to a non-ironing finishing method of high-strength retained pure cotton textiles. Background technique [0002] Cotton textiles are a common textile that is widely welcomed for its good comfort. However, pure cotton textiles are prone to wrinkling, especially after washing, which will affect the appearance and require ironing to achieve a smooth appearance. Non-iron anti-wrinkle finishing has emerged as the times require. At present, a mature 2D resin non-iron anti-wrinkle finishing technology has been formed, which can obtain a good appearance. 2D resin is an N-methylol finishing agent. Although the anti-wrinkle effect is good, 2D resin needs to use high-temperature baking under acidic conditions when finishing fabrics. Cellulose fibers will degrade under acidic and high-temperature conditions, causing great damage to fabrics. Poor abrasion resistance when worn. [0003] FAP...
