Embodiment 1

[0027] A kind of regenerated cotton, regenerated polyester and mixed-color spinning yarn, the weight percentage of regenerated polyester is 61%-65%, specifically 61%, 63%, 65%; the weight percentage of the regenerated cotton is 25%-30%, Concretely can be 25%, 28%, 30%; The weight percentage of melange spinning is 10%-20%, specifically can be 10%, 15%, 20%,

[0028] The regenerated cotton of this application uses cotton waste cloth corners as raw materials. When preparing, soak the waste cloth corners for 50-80 minutes. When soaking, add cleaning agent. The water used for soaking is added for cleaning in a ratio of 20-30:1. The ratio of agent, water and cleaning agent can be 20:1, 25:1, or 30:1. Specifically, the cleaning agent consists of 62 parts of water, 6 parts of ethanol, 12 parts of NaOH solution, 32 parts of anhydrous sodium metasilicate, 5 parts of sodium hydroxymethyl cellulose, 7 parts of sodium alkylsulfonate, alkylphenol polyoxygen Composed of 2 parts of vinyl eth...

Embodiment 2

[0031] A preparation process for regenerated cotton, regenerated polyester and mixed-color spinning, comprising the following steps:

[0032] S1: Dyeing, dyeing mixed-color spun yarn; mixing colored linen, recycled cotton, and polyester, 100kg as a combination, and then packing for later use; S2: Spinning, cleaning and carding the mixed fibers , drawing, roving, spinning, winding and other processes.

[0033] Sliver basis weight during spinning is 25g / 5cm; cylinder speed 350r / min; licker-in speed 890r / min; cylinder licker-in speed ratio 1:2.3; distance between licker-in roller and cylinder 0.26mm; distance between cylinder cover plate 0.5 mm , 0.32 mm, 0.32 mm, 0.32 mm, 0.36mm; cylinder distance 0.16mm. Processes such as blowing, carding, drawing, roving, spun yarn, and winding are all prepared by conventional methods in the art.

Embodiment 3

[0035] A kind of regenerated cotton, regenerated polyester and melange spinning, similar to Example 1, the difference is that the cleaning agent consists of 65 parts of water, 8 parts of ethanol, 13 parts of NaOH solution, 33 parts of anhydrous sodium metasilicate, hydroxymethyl Composed of 6 parts of sodium cellulose, 8 parts of sodium alkylsulfonate, and 3 parts of alkylphenol polyoxyethylene ether.

Abstract

The invention discloses regenerated cotton, regenerated polyester and blended colour yarn and a preparing process. The weight percent of regenerated polyester is 61 to 62%, the weight percent of regenerated cotton is 25 to 30%, the weight percent of blended colour yarn is 10 to 20%, the regenerated cotton selects cotton waste cloth corners to serve as raw materials, during preparing, the waste cloth corners are soaked, during soaking, a cleaning agent is added, and is composed of 60 to 70 parts of water, 5 to 15 parts of ethyl alcohol, 10 to 15 parts of NaOH solution, 30 to 35 parts of anhydrous sodium metasilicate, 4 to 8 parts of carboxymethyl cellulose sodium, 6 to 10 parts of alkyl sodium sulfonate and 2 to 4 parts of alkylphenol polyoxyethylene. Various high-property needs of a personfor textile products can be met, ventilating, light, comfortable, environment-friendly, firm, durable, wrinkle-preventing and balling-up-resisting properties can be achieved, the effects of peculiarsmell removal, bacterium resistance, mould proof, and static electricity resistance can be achieved, the comfort feeling is improved, the blended colour yarn is rich and changeable, the individual needs can be met, meanwhile, fabric has the good health care function, and the life needs of people can be enriched.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to regenerated cotton, regenerated polyester and mixed-color spinning and a preparation process. Background technique [0002] At present, with the improvement of people's living standards, people's requirements for material life are getting higher and higher. People begin to advocate a simple and natural way of life, so they also put forward higher requirements for various properties of textile products, such as Textile products require breathability, lightness, comfort, and environmental protection. [0003] Polyester fiber has excellent elasticity, and polyester fabric has high strength and elastic recovery ability. Therefore, it has the functions of firmness, durability, wrinkle resistance and pilling resistance. However, the recycled polyester fabric has poor hygroscopicity and poor air permeability, and it is easy to generate static electricity and absorb dust, s...
