Problems solved by technology

But the regenerated cellulose fabric also has the following disadvantages: because the moisture regain of the regenerated cellulose fabric is 12%-15%, the swelling degree in water reaches more than 50%, and the highest can reach 140%, so it is in the washing process. It is easy to absorb moisture and swell, and the fabric will feel hard; in terms of strength, the strength of this type of fabric will decrease by about 40% after wetting, and it is easy to deform and difficult to recover under a small load, and the elasticity is also poor. The fabric is easily damaged under severe washing conditions. Therefore, the fabric is easy to wrinkle and has poor abrasion resistance

Embodiment 1

[0023] A finishing agent for regenerated cellulose fabrics, the finishing agent uses water as a solvent, including 20g / L of anti-shrinkage and anti-wrinkle processing resin, 20g / L of catalyst, 30 / L of fiber protection agent, 20 / L of water-based polyurethane and softener 30 / L, of which,

[0024] The resin is GL-45 resin;

[0025] Catalyst is F-M catalyst;

[0026] Fiber protection agent is PA-6 fiber protection agent;

[0027] The softener is HF-10R and silicone oil CGF softener with a weight ratio of 2:1.

Embodiment 2

[0029] A post-finishing process for regenerated cellulose fabrics. The post-finishing process is to soak the fabric in the post-finishing agent of Example 1 and roll the resin, and bake and cross-link the fibers in a non-expanded state after drying, wherein,

[0030] In the step of rolling resin, the surplus rate is 60%;

[0031] In the drying step, the drying temperature is 80°C;

[0032] In the baking step, the baking step is 175° C., and the baking time is 3 minutes.

Embodiment 3

[0034] A finishing agent for regenerated cellulose fabrics, the finishing agent uses water as a solvent, including 30g / L of anti-shrinkage and anti-wrinkle processing resin, 30g / L of catalyst, 40 / L of fiber protection agent, 30 / L of water-based polyurethane and softener 40 / L, of which,

[0035] The resin is GL-45 resin;

[0036] Catalyst is F-M catalyst;

[0037] Fiber protection agent is PA-6 fiber protection agent;

[0038] The softener is HF-10R and silicone oil CGF softener with a weight ratio of 7:1.

Abstract

The invention relates to the technical field of textiles, in particular to a regenerated cellulose fabric after-finishing agent and an after-finishing process. The after-finishing agent comprises shrink-proof and crease-resistant processing resin, a catalyst, a fiber protective agent, waterborne polyurethane and a softener. The after-finishing process comprises the following steps of soaking the fabric in the after-finishing agent, rolling the resin, drying, and baking and crosslinking in a fiber non-puffing state. By using the after-finishing agent and the after-finishing process, the regenerated cellulose fabric can be prevented from swelling and hardening in wet water, the wet strength is improved, the wearability of the regenerated cellulose fabric can be greatly improved, and a foundation is laid for wide application of the regenerated cellulose fabric.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a finishing agent for regenerated cellulose fabrics and a finishing process. Background technique [0002] With the development of society and the continuous progress of science and technology, people's awareness of environmental protection has gradually increased, and the requirements for textiles have also shown a trend of natural, diversified and functional. Regenerated cellulose fiber has been favored by people because of its biodegradable characteristics. widespread favor. The emergence of regenerated cellulose fiber has also alleviated the current situation of scarcity of social resources, and has become an indispensable and important component of fabric composition, with broad development prospects. [0003] Regenerated cellulose fiber refers to fibers made of natural cellulose such as wood, cotton linters, hemp, bamboo, etc., including viscose fiber, modal fiber, cupro ...
