Embodiment Construction

[0019] see figure 1 , the anti-aging spunbond non-woven fabric processing technology, including the following steps in turn:

[0020] Auxiliary agent 1: Add antioxidant and light stabilizer to polypropylene chips. The amount of oxidant added is 0.8-1.0% of the amount of polypropylene chips, and the amount of light stabilizer is 0.2%-0.4% of the amount of polypropylene chips. Polypropylene chips are thoroughly mixed with antioxidants and light stabilizers. The selected light stabilizer is a hindered amine light stabilizer, the chemical name is bis(2,2,6,6-tetramethyl-4-piperidinyl) sebacate, and its light stabilization effect is better than the general Ultraviolet absorber, used in combination with antioxidants can improve heat resistance, further improve aging resistance, good compatibility with polymers, excellent thermal stability, can be used for high temperature processing, and can provide maximum protection for polymers, Reduce damage from UV exposure. This product is ...

Abstract

The invention discloses a technique for processing ageing resistant spun-bond non-woven fabrics, comprising the following steps of in turn: addition of additives, slice transportation, extrusion, filtration via a fused mass filter, spinning, web forming, hot rolling to form fabric and so on. The technique adds a certain amount of antioxidants and light stabilizers, and can decompound hydroperoxides, prevent generation of free radicals, absorb harmful ultraviolet radiation and consume energy into heat so as not to cause photosensitization, thereby the aim of ageing resistance is achieved. The products can be kept degenerative in the sun for 6 months to the maximum degree, have good ageing resistance and good traction force, and are soft, dry, nontoxic and environment-friendly; the service life of the products is prolonged; moreover, the products can be naturally degraded after use, thereby no environmental pollution is caused. The technique can be widely used for manufacturing various sunshades and beach tents and in the fields such as agricultural harvest cloth, car covers and so on.

Description

【Technical field】 [0001] The invention relates to a textile technology, more particularly, to a processing technology of a spunbond non-woven fabric with anti-aging function. 【Background technique】 [0002] Spunbond nonwovens are sheet-like fiber materials made of thermoplastic polymer compounds such as polypropylene as raw materials, which are melt-spun, drawn and laid, and then consolidated by hot rolling. [0003] Since polypropylene non-woven fabrics are easy to age under ultraviolet radiation, when the products are used in agricultural fabrics, such as greenhouse sunshade products, weed protection fabrics, bagging of fruits, protection fabrics for vegetables and flowers, there is a long service life. Long and other defects. [Content of the invention] [0004] The purpose of the present invention is to solve the problems in the prior art, and propose an anti-aging spunbond non-woven fabric processing technology, and the produced products can have good anti-aging prope...
