Embodiment 1

[0034] Embodiment 1: (product A)

[0035] The mass percent of each component of the acid dye light fastness improving agent of the present embodiment is:

[0036]

[0037] Butylmethoxydibenzoylmethane, 3-[3-(2H-benzotriazol-2-yl)-4-hydroxy-5-tert-butylphenyl]-propionic acid-polyethylene glycol 300 ester and tetrakis (2,2,6,6-tetramethyl-4-piperidinyl) 1,2,3,4-butane tetracarboxylate were added to the reaction kettle, stirred for 20min to mix evenly, slowly added ten Stir isopropyl tetra-acid for 30 minutes, stir evenly, add oleic acid and oleic acid polyoxyethylene (EO~18) ether and stir for 45-60 minutes, then heat up to 60-65°C, all reactants dissolve and become transparent liquid, gradually Add water, stir at high speed for 45-60min, cool down, the reaction product is a milky white emulsion, stand still for a week, no precipitation and floating matter appear.

Embodiment 2

[0038] Embodiment 2: (product B)

[0039]

[0040] Butylmethoxydibenzoylmethane, 3-[3-(2H-benzotriazol-2-yl)-4-hydroxy-5-tert-butylphenyl]-propionic acid-polyethylene glycol 300 ester Add tetrakis(2,2,6,6-tetramethyl-4-piperidinyl) 1,2,3,4-butane tetracarboxylate into the reaction kettle respectively, stir for 20 minutes to mix evenly, slowly add Stir isopropyl myristate for 30 minutes, stir evenly, add oleic acid (lubricant) and oleic acid polyoxyethylene (EO-18) ether (emulsifier) ​​and stir for 45-60 minutes, then heat up to 60-65°C, react All the substances were dissolved and turned into a transparent liquid. Gradually add water, stir at high speed for 45-60min, cool down, the reaction product is a milky white emulsion, stand still for a week, no precipitation and floating matter appear.

Abstract

The invention discloses an acidic dye light fastness improving agent and application thereof. The acidic dye light fastness improving agent comprises the following components in percentage by mass: 7.0 to 15.0 percent of an ultraviolet absorbent, 5.0 to 15.0 percent of a light stabilizer, 10.0 to 20.0 percent of a solvent, 3.0 to 6.0 percent of a lubricating agent, 3.0 to 6.0 percent of an emulsifier and the balance of deionized water. The acidic dye light fastness improving agent does not have irritation, corrosivity and volatility, so the acidic dye light fastness improving agent has littleinfluence on finishing plant production and use environments; the adding amount is small and is about 2.0 percent of the weight of fabric, the adding cost is low and the effect is durable; and the acidic dye light fastness improving agent is added in a one-bath dyeing mode with the dye, or is added in a dip dyeing mode after dyeing, or is added in a shaping process padding mode, so the color yieldand the vividness of dyeing textiles are not influenced. The production process is simple, and grinding equipment and a grinding process are not needed. The acidic dye light fastness improving agenthas high washing resistance, is attached to the fabric in a one-bath dyeing mode with the fabric and still has high light fastness after being washed with water for 10 times.

Description

【Technical field】 [0001] The invention relates to an agent for improving the light fastness of acid dyes and an application thereof, belonging to the technical field of textile auxiliaries. 【Background technique】 [0002] Nylon and nylon / spandex fabrics are often used to make swimwear fabrics. They are also a kind of polymer material. They are dyed with acid dyes and belong to an outdoor textile fabric. They are easy to fade when worn outdoors and exposed to strong sunlight for a long time. Problems have plagued the swimwear fabric processing industry. There are many factors that affect the light fastness of swimsuit fabrics, but the main reason is the development of modern industry. The application of freon destroys and thins the ozone layer and forms an ozone hole. Excessive ultraviolet radiation on the surface of the earth not only affects human health, but also Accelerates the aging of polymer materials for outdoor use. Acid dyes absorb ultraviolet rays in sunlight, an...
