Strength-improvable blended regenerated cotton yarn and preparation method thereof

Abstract

The present invention discloses a strength-improvable blended regenerated cotton yarn which is characterized being prepared from the following raw material by weight: 30-33 parts of waste cotton fabrics, 15-17 parts of cotton yarn leftover material, 2-3 parts of glycerin, 8-10 parts of copper ammonia fibre, 3-4 parts of starch, 3-5 parts of nano-silica, 39-44 parts of polypropylene, 3-5 parts of nano-zinc oxide, 12-14 parts of liquid paraffin, 9-10 parts of nano-titanium dioxide, 1.5-parts of carboxymethyl cellulose, 1-2 parts of glyceryl stearate, and proper amount of water; the starch, the nano-silica and other components are used for prepare processing slurry to process waste cotton fabric renewable fiber, the strength and sunscreen resistance of the fiber are improved, then the waste cotton fabric renewable fiber is mixed with the copper ammonia fiber, and strength and hand feel of the fiber are improved by cotton carding; the strength-improvable blended regenerated cotton yarn is prepared by addition of the nano-titanium dioxide and the nano-zinc oxide-modified polypropylene staple fiber for blending, the strength of the cotton fiber is improved, and the strength-improvable blended regenerated cotton yarn has the characteristics of easy staining and grinding resistance.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a blended regenerated cotton yarn capable of improving strength and a preparation method thereof. Background technique [0002] With the rapid increase of the global population, all countries in the world will control the use of cultivated land, and the planting of cotton, hemp, and mulberry trees for sericulture will be restricted, and the traditional cotton textile raw materials will be subject to multiple constraints. Relevant data show that in 2010, the amount of leftover materials and other raw materials used in domestic recycled cotton yarns can reach about 3 million tons in total. It is estimated that 50% of the cotton is recycled yarn, and the cotton output per mu is 200 kg, which is equivalent to the output of more than 7 million mu of cotton fields. Regenerated yarn not only realizes the recycling of resources, saves limited resources, but also solves the problem of s...

Problems solved by technology

Polypropylene fiber is light in weight, high in strength, good in elasticity, wear-resistant and corrosion-resistant, has electrical insulation and warmth retention properties, low moisture regain, low price, and good chemical resistance. It is widely used in the field of decorative fabrics, but due to The poor heat resistance and aging resistance of polypropylene fiber limit its application in the field of clothing
