          Principle and application of knitted weft knitted three-dimensional spacer fabric

Nowadays, fashion knitted fabrics have already broken through the application scope of underwear, continuously extended to deeper and wider fields, and can complete some functions and structures that other knitted fabrics cannot achieve. The structure of three-dimensional spacer knitted fabric is like a sandwich, which is composed of two independent surface layers and intermediate connecting layers. When the knitting machine is incorporated into the connecting line, the gap between the front and back layers of fabrics can be enlarged to weave hollow double-layer fabrics. If monofilament is used as the connecting wire, such as polyester, polyamide or polypropylene with high bending rigidity, the two surface layers can be propped up and separated to form an elastic, thick and air storage spacer fabric.

When weaving, fluffy yarn can be added between the positive and negative layers of fabric to produce quilted flocs. If equipped with computer jacquard equipment, high-grade quilting products can be woven. By using the double-sided needle selecting electronic jacquard knitting machine, the double-sided fabric with jacquard effect on both sides can be knitted, and the performance characteristics of fiber raw materials, especially functional fiber raw materials, can be fully utilized. The sportswear fabric produced by hygroscopic moisture conducting fiber combined with knitted sandwich structure can well adjust the "microclimate" between clothing and human body, and occupies a considerable share in the thermal underwear market.

3D knitting technology can realize the multi-dimensional structure of fabric on weft knitting machine, so as to design the organization forms with different structures and functions, such as giving the fabric permeability, water management and other properties, so that each layer of the fabric can play different functions, and no functional additives are used in the dyeing and finishing process. With the environmental protection standard control of each process, it can produce garment fabrics without additives.

The structural characteristics of knitted spacer fabric and the characteristics of spacer yarn endow the spacer fabric with stable structure and unique physical properties, making it light, soft and comfortable, with good air permeability and compression resistance, good heat preservation, washing resistance and aging resistance, moisture absorption, shock absorption, antibacterial finishing and flame retardant finishing. Knitted spacer fabric is used for shoe lining. It can be connected by two surface fabrics with different properties to form a unique fabric structure. It has good compression elasticity, shock absorption, air and moisture permeability, as well as high thermal insulation and temperature regulation.
