Denim anti-oxidant yellowing finishing agent and preparation process thereof

Abstract

The invention relates to a denim anti-oxidant yellowing finishing agent and a preparation process thereof. The denim anti-oxidant yellowing finishing agent is prepared by mixing a component A and a component B in a weight ratio of 1 to 1, wherein the component A comprises the following components in percentage by weight: 10%-15% of alcohol amine, 8%-12% of dodecyl dimethyl amine ethyl lactone, 5%-10% of fatty alcohol-polyoxyethylene ether, 10%-30% of distilled water, 10%-20% of benzotriazole and the balance of water; the component B comprises the following components in percentage by weight: 8%-10% of fatty acid amide, 50%-60% of distilled water, 1%-3% of glacial acetic acid, 1%-2% of a calcium chloride solution, 15%-30% of a polyamine compound and the balance of water. Compared with the prior art, the denim anti-oxidant yellowing finishing agent has the advantages of being lasting in yellowing resistance, and the like.

Description

Technical field [0001] The invention relates to an antioxidant yellowing finishing agent, in particular to a manufacturing process of an anti-oxidizing yellowing finishing agent for denim. Background technique [0002] With people's pursuit of fashion, denim clothing washing requirements are getting higher and higher. The circulation process of denim clothing, the hanging samples of specialty store windows, various lights, as well as ozone in the atmosphere, ultraviolet rays, and nitrogen oxides in exhaust emissions, etc. will cause varying degrees of local yellowing of denim (mainly exposed parts, folded The edge part), may form a horizontal yellow spot, or half dark and half light yin and yang denim; secondly, the light-toned style of spring and summer denim, most of the denim has been bleached and decolorized by sodium hypochlorite (bleaching water), and it is difficult to remove the residual chlorine. As a result, the residual chlorine has great fading and yellowing on the c...

Problems solved by technology

And the anti-yellowing finishing agent reported at present is generally used on materials such as cotton fiber, spandex, discloses polyamide fiber, spandex and its blended fabrics with compound heat-resistant yellowing finishing agent as invention patent 201310512529.7, mainly consists of synergist, synergist Composed of anti-oxidant and main antioxidant, nylon, spandex and their blended fabrics can significantly improve the yellowing and color change of nylon, spandex and their blended fabrics during processing after being treated with the solution of the compound anti-yellowing finishing agent , but the finishing agent cannot be used in denim

At present, there are more anti-ozone softeners on the market to prevent denim yellowing, but the effect is not ideal. It will start to yellow after 7 days or 10 days, and the anti-yellowing ability is not durable enough; and the recent anti-ultraviolet agents are not ideal when used alone
