AI Technical Summary

Problems solved by technology

However, if the product needs to be treated at high temperature, the perspiration fastness and water fastness will be seriously reduced after high temperature treatment (washing fastness is good)
Dark perspiration fastness and water stain fastness are usually only about 2 grades in multi-fiber staining, and it is difficult to improve using traditional techniques

Embodiment Construction

[0019] The following examples facilitate a better understanding of the present invention, but do not limit the present invention. The experimental methods in the following examples are regarded as conventional methods unless there are special circumstances.

[0020]

[0021] After testing, the above embodiments 1-4 all belong to the preparation method of the present invention, and are acrylic fiber fixatives with a dark brown liquid appearance and a pH value of 8-9 (10% aqueous solution). According to the liquor ratio of 10:1, fix the acrylic fiber at a general temperature of 60 °C for 30 minutes. It is found that it has a strong affinity for dyes that have not reacted with the fiber, and can completely strip the free dye and stably disperse it in the fixed color. In the bath, it is discharged with the waste liquid, and at the same time, this product can form a film on the surface of acrylic fiber. Therefore, the color treated by this product has excellent fastness; the yar...

Abstract

The invention provides an acrylic color fixing agent, comprising the following components according to parts by weight: 10-30 parts of acrylamido methylpropanesulfonic acid, 10-20 parts of sodium lignosulfonate, 1-5 parts of polyvinylpyrrolidone, 0.2-1 part of methylisothiazolinone, and 40-70 parts of water. The invention also provides a preparation method of the acrylic color fixing agent, comprising: mixing well the components according to a matching ratio and reacting at high temperature. Fiber treated with the acrylic color fixing agent of the invention has high color fastness; the acrylic color fixing agent has high affinity to a dye not reacted with the fiber; the impact on color of yarn or fabric color-fixed with the acrylic color fixing agent is low; water can be effectively saved for a dyeing plant, and production efficiency can be effectively improved; the acrylic color fixing agent is a special surfactant and is free of bubbles.

Description

technical field [0001] The invention belongs to the field of textile printing and dyeing auxiliaries, and more particularly relates to an acrylic fiber color-fixing agent. Background technique [0002] Acrylic fiber is generally polyacrylonitrile fiber. The performance of polyacrylonitrile fiber is very similar to wool, with good elasticity. When the elongation is 20%, the rebound rate can still maintain 65%. It is fluffy, curly and soft, and its warmth retention is 15% higher than that of wool. Synthetic wool. Strength 22.1~48.5cN / tex, 1~2.5 times higher than wool. Excellent light fastness, one year exposure in the open air, the strength is only reduced by 20%, it can be made into curtains, curtains, tarpaulins, gun clothing, etc. It is resistant to acids, oxidants and general organic solvents, but poor alkali resistance. [0003] Acrylic fiber is called artificial wool. It has the characteristics of softness, bulkiness, easy dyeing, bright color, light resistance and a...
