Embodiment 1

[0029] Prepare the viscose spinning stock solution according to the ordinary viscose fiber production process, take 10 kg of the viscose spinning stock solution, add anti-wrinkle agent, and ensure that the composition ratio is:

[0030]

[0031] The anti-wrinkle agent adopts urea-formaldehyde resin, which is added to the viscose spinning stock solution according to 10% of the mass of the first type of cellulose, which is equivalent to 0.9% of the mass of the system. Shaping, drafting, cutting, refining, and high-temperature drying to obtain native anti-wrinkle viscose staple fibers.

Embodiment 2

[0033] Prepare the viscose spinning stock solution according to the ordinary viscose fiber production process, take 10 kg of the viscose spinning stock solution, add anti-wrinkle agent, and ensure that the composition ratio is:

[0034]

[0035]The anti-wrinkle agent adopts dimethylol dihydroxyethylene urea, which is added to the viscose spinning stock solution according to 16.7% of the mass of the first cellulose, which is equivalent to 1% of the mass of the system, mixed evenly, and transported to the spinning In the silk section, it is shaped, drawn, cut, refined, and dried at high temperature according to the ordinary viscose fiber spinning process to obtain the original anti-wrinkle viscose staple fiber.

Embodiment 3

[0037] Prepare viscose spinning stock solution according to common viscose fiber production process, get 10 kilograms of viscose spinning stock solution, add anti-wrinkle agent and catalyst, ensure that its composition ratio is:

[0038]

[0039]

[0040] The anti-wrinkle agent adopts 1,2,3,4-butane tetracarboxylic acid, which is added to the spinning stock solution according to 10% of the mass of the first cellulose, which is equivalent to 0.9% of the mass of the system, and the catalyst is sodium phosphite. It is added to the viscose spinning stock solution according to 0.1% of the system quality, mixed evenly, transported to the spinning section, and shaped according to the ordinary viscose fiber spinning process, drafted, cut, refined, and dried at high temperature to obtain raw Wrinkle-resistant viscose staple fiber.

[0041] The anti-wrinkle agent can be a multi-component mixture or a single component. The anti-wrinkle agent used in this example is 1,2,3,4-butane t...

Abstract

The invention relates to a raw crease-resistant viscose spinning solution and fiber and a preparation method. The raw crease-resistant viscose spinning solution comprises the following components of, in percentage by mass, 4%-6% of sodium hydroxide, 6%-9% of alpha cellulose, 0.5%-1% of a crease-resistant agent, 0%-0.1% of a catalyst and the balance water and a small amount of impurities. The raw crease-resistant viscose fiber is formed by physically blending and spinning a viscose spinning solution containing alpha cellulose and a crease-resistant agent, and belongs to the field of manufacturing of regenerated cellulose fibers through a textile technology. The raw crease-resistant viscose fiber has the characteristics of softness, comfort, sweat absorption and the like, also has better mechanical properties and good crease resistance, and is different from an after-finishing crease-resistant fabric, the crease-resistant agent and the cellulose fiber in the raw crease-resistant viscose fiber achieve molecular fusion, the defect that the viscose fiber is prone to wrinkling is overcome, and the defects that the after-finishing crease-resistant fabric is poor in washability and prone to yellowing and damage in strength are overcome.

Description

technical field [0001] The invention relates to a raw anti-wrinkle viscose spinning stock solution, fiber and a preparation method, belonging to the field of viscose fiber manufacturing in the textile industry. Background technique [0002] Viscose fiber has been widely used from clothing to non-woven products for more than 100 years. During the application process, people found that soft and comfortable viscose fiber clothes are easy to deform and have poor dimensional stability, and the clothes made of viscose fiber are easy to wrinkle, which leads to the deterioration of the appearance of the textile and directly results in a short wearing life. Most of the viscose fabrics currently on the market appear in the form of blending with cotton or other synthetic fibers to improve the above shortcomings. [0003] Up to now, there is no viscose staple fiber product that can provide native anti-wrinkle performance available or publicly reported. Now the anti-wrinkle technology ...
