Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a method for non-ironing finishing of high-strength pure cotton textiles, which not only overcomes the problem of poor water solubility, but also avoids the disadvantages of ammonia modification; Good, because it is cross-linked under alkaline conditions, there is no problem of high-temperature acid degradation of cellulose, and the strength retention is high

Embodiment 1

[0016] Add 120g of FAP, 20g of sodium carbonate, and 2g of sodium hydroxide into 1L of water, heat to partially hydrolyze and completely dissolve the FAP, and use it as a finishing solution. Immerse the pure cotton fabric in the finishing solution, soak it completely, dehydrate to 70% of the liquid retention rate, dry at 80°C for 1min, then bake at 140°C for 3min, wash with water, neutralize with HAc, and pad with silicone The softener is then dried at 80°C to obtain the finished product.

Embodiment 2

[0018] Add 100g of FAP and 20g of sodium carbonate into 1L of water, heat to partially hydrolyze and completely dissolve the FAP, and use it as a finishing solution. Padding the pure cotton fabric with the finishing solution, with a liquid retention rate of 60%, steaming it for 2 minutes at 120°C and a humidity of 60%, washing it with water, neutralizing it with HAc, padding it with a silicone softener, and drying it at 80°C to obtain 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...
