Problems solved by technology

But the comfort of the highly elastic fabric prepared by this patent is not good
[0004] In addition, the structure of the grasping and shearing machine used for fabrics in the prior art is single, the grasping and shearing process is relatively short, and the floating wool on the surface of the fabric cannot be removed well, so the surface of the fabric is rough and the quality is poor

Abstract

The invention discloses a blended elastic knitted fabric and a preparation method thereof. The preparation method comprises the steps of: a step A of uniformly mixing polyvinyl chloride, ethylene propylene rubber, sodium stearate, bamboo charcoal powder and nanometer titania, heating into a molten state, adding a coupling agent, cellulose ester and sodium alga acid, continuing to uniformly mix, and extruding from a spinneret plate to obtain synthetic fibers; a step B of alternatively arranging the synthetic fibers, cotton fibers and modal fibers according to a sequence of 2:(1 to 3):(1 to 3),and obtaining single yarns by a spinning process; a step C of carrying out cabling on the single yarns to form folded yarns; a step D of carrying out weaving on composite yarns by a rib knitting machine to obtain a gray fabric; a step E of carrying out high-temperature presetting on the gray fabric; and a step F of carrying out ball wool opening and shearing treatment on the gray fabric to obtainthe blended elastic knitted fabric. The blended elastic knitted fabric prepared by the preparation method has high elasticity, is comfortable to wear, excellent in moisture permeability and air permeability, simple in preparation process and easy in operation of a production process, and has wide application prospect.

Description

technical field [0001] The invention relates to the technical field of knitted fabrics, in particular to a blended elastic knitted fabric and a preparation process thereof. Background technique [0002] Wearing fabrics should not only meet the advantages of high softness, breathability and sweat absorption, but also have certain elasticity. However, existing elastic fabrics lack sufficient elastic deformation capacity, and fabrics with high elasticity often use dense fabric structures. The small gaps between the yarns seriously affect the moisture permeability and breathability of the fabric, which in turn affects the comfort of wearing. [0003] Chinese patent CN103668700A discloses a high-elastic fabric and its preparation method, which consists of ethylene-propylene rubber, polyethylene glycol, monomethylaniline, polyphenylene ether, calcium stearate, fatty acid polyvinyl chloride ether, and a coupling agent. Originally mixed and heated to a molten state, adding a coupli...
