Different knitting methods, knitted fabrics can be divided into: weft knitting, warp knitting, warp and weft composite knitting

Knitting production process is short, raw materials have strong applicability, the product has a wide range of use, the needle machine has high production efficiency, labor intensity is low, the machine noise is small, and the area is small

The coil is the basic structural unit that constitutes the knitted fabric

Coil composition: coil, needle arc, subsidence arc

Main physical and mechanical indicators of knitted fabrics: coil length, density, underfill factor, thickness, dispersibility, hemming

According to the needle type, it can be divided into crochet machine, tongue needle machine, compound needle machine

The reason for the knitting machine is as follows: a line or a let-off mechanism, a weaving mechanism, a pulling and winding mechanism, a transmission mechanism and an auxiliary mechanism

Auxiliary devices include: flower-type mechanism, automatic control mechanism, automatic refueling device, cleaning and dust removal device, various stop devices, counting devices, etc.

Types of knitted fabrics: original tissue, change tissue, color texture

Weft flat-needle tissue

Double ribbed tissue commonly known as: cotton wool tissue

Jacquard organization whose structural units consist of coils and floats

Jacquard organization can be divided into single-sided, double-sided, which has a single color (plain) and multi-colored points

Single-sided weft-knit jacquard can be divided into two types: uniform structure and non-uniform structure according to whether or not the number of longitudinal turns of the longitudinal coils in each complete group is large.

There are three main categories of embroidery yarn organization: embroidered plating organization, overhead plating organization, exchange of plating organization

The yarn laying method of the pad yarn is generally: straight pad type, displacement type or hybrid type. At present, most of the production of velveteen cloth adopts 1:2 displacement type.
