Problems solved by technology

[0003] Existing knitted fabrics are made of thread and sand materials into coils through knitting. The coil is the basic unit of knitted fabrics and is a space curve. Its projection on the fabric plane is composed of approximate straight line segments and arc line segments. It is a coil column, and the arc is called a circle arc, and then the coils are strung together to form a fabric, so that the adjacent yarns wrap around each other to form a stable relationship. Single-line sand and wo

Abstract

The invention relates to a production process for improving comfort of blended knitted fabrics. The production process includes steps of blended yarn feeding, clearing, yarn laying-in, closing, looping, kinking, knocking-over, loop formation and drawing to form single rib stitches, every three routes of the single rib stitches form a cycle to obtain a knitted fabric, a first route refers to (n+1)+n rib stitches, a second route refers to n+n rib stitches, and a third route refers to n+(n+1) rib stitches; after-finishing, scutching and forming are performed prior to soaking in softening agent solution, and knitting is carried out to obtain the blended knitted fabrics. By three routes of different cyclic rib stitches, transverse and longitudinal loops in a free state are perpendicular withoutskewing, less proneness to curling and running is realized, elongation meets human body or utilization demands, the bundling performance and coverage of the fabrics are improved, tear strength of thefabrics is enhanced, retraction is avoided, and accordingly comfort of the blended knitted fabrics is improved.

Description

technical field [0001] The invention relates to a production process for improving the comfort of blended knitted fabrics, and belongs to the technical field of knitted fabric production processes. Background technique [0002] With the continuous development of social science, a variety of textile materials have been produced, combined with stable and mature spinning technology and fiber characteristics, to meet people's new requirements for the application of textiles in clothing culture and improve the quality and function, especially blended The material is made of chemical fibers mixed with other natural fibers such as cotton wool, silk, hemp, etc., and combines the advantages of various fiber materials, and will be widely used in the field of knitted fabrics. [0003] Existing knitted fabrics are made of thread and sand materials into coils through knitting. The coil is the basic unit of knitted fabrics and is a space curve. Its projection on the fabric plane is compos...
