Embodiment 1

[0020] An environment-friendly anti-fading agent, the anti-fading agent comprises the following components by weight:

[0021] 3 parts sodium silicate;

[0022] 10 parts of phenol;

[0023] 12 parts of phenolsulfonic acid;

[0024] 7 parts of composite catalyst;

[0025] 12 parts of salt water;

[0026] 7 parts silkworm cocoons;

[0027] Modifier 2 parts.

[0028] The composite catalyst is a mixture of potassium hydroxide and boric acid.

[0029] Soak silkworm cocoons in warm water for 1 hour, the outer layer of silk of the soaked silkworm cocoons will be adjusted, and then become silkworm cocoons.

[0030] The modifier is urea or hydrogen peroxide.

Embodiment 2

[0032] An environment-friendly anti-fading agent, the anti-fading agent comprises the following components by weight:

[0033] 5 parts of sodium silicate;

[0034] 15 parts of phenol;

[0035] 13 parts of phenolsulfonic acid;

[0036] 8 parts of composite catalyst;

Abstract

The invention discloses an environment-friendly color fading resisting agent which is prepared from, by weight, 3-7 parts of sodium silicate, 10-20 parts of phenol, 12-15 parts of phenolsulfonic acid, 7-9 parts of composite catalyst, 12-18 parts of brine, 7-11 parts of cocoon silk and 2-4 parts of modifying agent. The composite catalyst is the mixture of potassium hydroxide and boric acid. Silkworm cocoons are soaked in warm water for 1-2 h, and one layer of silk on the outer surface of the soaked silkworm cocoons is drawn to become cocoon silk. According to the color fading resisting agent, the phenol, the phenolsulfonic acid and the composite catalyst are adopted for a condensation reaction, the modifying agent is added into the mixture for modification, and the acid reaction resisting type color fading resisting agent is obtained; chemical damage is small, the brine has the certain color fixing effect on the fabric, alkaloid in mulberry leaf water has the antibacterial effect on the fabric, and the cocoon silk can increase the color brilliance of the fabric.

Description

technical field [0001] The invention relates to an anti-fading agent, in particular to an environment-friendly anti-fading agent. Background technique [0002] In the dyeing process of nylon fabrics, acid dyes are used for dyeing in most cases. Since acid dyes are anionic dyes with small molecular weight and good water solubility, some dyes bonded to fibers in aqueous solution will dissociate, resulting in nylon after dyeing. The washing fastness, dry and wet rubbing fastness, and perspiration fastness of the fabric are poor, and because the acid dye itself has a low level of light fastness, it is necessary to use a color fixing agent to improve the color fastness of the nylon fabric. [0003] Therefore, it is necessary to provide a new technical solution to solve the above problems. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an environment-friendly anti-fading agent with little harm and good color fixation...
