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

Abstract
The present invention discloses blended regenerating cotton yarns capable of improving ultraviolet ray resistance, wherein the blended regenerating cotton yarns are characterized in that the blended regenerating cotton yarns are prepared from the following raw materials by weight: 40-43 parts of waste cotton fabric, 15-17 parts of cotton yarn leftover, 2-2.5 parts of phosphoric ester starch, 1.5-2 parts of pectin, 6-8 parts of pure acrylic emulsion, 0.5-0.7 part of dodecanol polyoxyethylene ether sodium sulfate, 39-44 parts of polypropylene, 3-5 parts of nanometer zinc oxide, 12-14 parts of liquid paraffin, 9-10 parts of nanometer titanium dioxide, 1.5-2 parts of carboxymethyl cellulose, 1-2 parts of glyceryl stearate, and a proper amount of water. According to the present invention, the waste cotton fabric is used to regenerate the fibers, and the obtained fibers and the surface modified polypropylene short fibers are subjected to drawing and blending to obtain the blended regenerating cotton yarns of the present invention, such that the characteristics of various fibers are neutralized, the disadvantage of poor sunscreen property of the cotton fibers and the polypropylene fibers are overcome, characteristics of strength enhancing, good elasticity, wear resistance, corrosion resistance, good warm keeping and product quality improving are provided, and the waste cotton regeneration is adopted so as to save the cost.
Description
technical field [0001] The invention relates to the technical field of textiles, in particular to a blended regenerated cotton yarn capable of improving anti-ultraviolet performance 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 sol...
