Embodiment

[0030] A method for preparing a super-elastic heterochromatic cotton-feeling elastic false-twisted composite yarn, comprising the following steps:

[0031] Step 1: raw material preparation: polyurethane 6 or polyurethane 66 (A) and polyester fiber (B);

[0032] Step 2: Texturing process: Polyurethane 6 or polyurethane 66 (A) and polyester fiber (B) are combined to form elastic false-twist composite yarn. First, polyurethane 6 or polyurethane 66 pre-oriented yarn is used as raw material to undergo high-shrinkage false-twisting processing Finally, at the front roller of the interlacing nozzle, polyester false-twisted yarns are introduced, and composite false-twisted yarns are formed by interlacing through the interlacing nozzles. The specific operations are as follows: polyurethane 6 or polyurethane 66 (A) and polyester fiber (B) respectively Pulled out from the yarn bobbin, polyurethane 6 or polyurethane 66 (A) passes through the raw material creel → 1 roller → twist stopper → ...

specific Embodiment

[0053] The texturing machine imported from Japan is selected, and the A raw material POY is polyester ammonia 66 POY with a specification of 27dtex / 20f. It is drawn through POY 1.2-1.5, passed through a hot box at 200-230°C, and passed through a special modified spindle needle dummy. The twister is 5000~7000T / M, and the nylon DTY with a fineness of 22dtex is obtained. B Raw material Nanya 30-36-CD.DTY, in which the pressure processed by the nozzle is 0.5~0.90kg.

[0054] The invention adopts a special texturizing process, utilizes a super low processing speed, and uses a rotor texturizer to replace the ordinary polyester disc and belt-type texturizing process, so that it has permanent ultra-high elasticity and waxy thick texture at the same time. Cotton feel, polyurethane 6 or polyurethane 66 is used as elastic material. The raw materials of the two components are processed at a specific dyeing temperature and utilize the different thermal shrinkage stresses of the two sets o...

Abstract

The invention discloses a preparation method of ultra-high-elasticity different-color cotton-feeling elastic false twisting composite yarns and a production process of a different-color cotton-feelingelastic fabric. A special elasticizing process and an ultra-low processing speed are adopted, meanwhile, a rotor elasticizer replaces a common polyester plate and a belt type elasticizing process, thus, the yarns have permanent ultra-high elasticity and thick cotton feeling simultaneously, and elasticizing raw materials are polyurethane 6 or polyurethane 66. The polyurethane 6 or 66 and raw materials of two components of polyester filament fibers have special different-color cotton feeling under the conditions the dyeing temperature is specific in post processing and the two groups of yarns have the following different thermal contraction stresses: polyurethane 6.2% and polyester 3.2%. By the polyurethane 6 or polyurethane 66 processing method, the curling contraction rate of nylon yarnscan be increased effectively, and can be increased to be about 60% from 30% in the prior art, thus, the yarns are curly and fluffy, the elasticity of the yarns is greatly improved, requirements for elastic fabrics such as sportswear fabrics, elastic outdoor jackets and skiing clothes are met, and the requirements of the markets are greatly met.

Description

technical field [0001] The invention belongs to the field of fabric development and production of textile yarns, and in particular relates to a preparation method of an ultra-high elasticity and different-color cotton-feel elastic false-twisted composite yarn and a production process for a different-color cotton-feel elastic fabric. Background technique [0002] The fabrics and ordinary products that appear on the market generally also have fabrics that feel cottony. The general method of making is relatively common and single. Some are made by using cotton directly, and some get a cotton feel through air textured yarns or through fine denier perforated yarns. These do not have the function of different colors and elasticity. Contents of the invention [0003] Purpose of the invention: In order to solve the deficiencies in the prior art, the present invention provides a method for preparing super-high elastic false-twisted composite yarn with different-color cotton-feel ...
