Description
Technical Field
The utility model belongs to the field of design and preparation of fabrics for knitted clothes, and particularly relates to a high-elastic light warp-knitted spacer fabric.
Background
Warp-knitted spacer fabrics, particularly elastic warp-knitted spacer fabrics, are relatively heavy, because spacer yarns need to be looped on two needle beds when a multi-bar double-needle-bed warp knitting machine is used for weaving the spacer fabrics, the loops are long, the yarn consumption is large, the spacer yarns of the elastic warp-knitted spacer fabrics generally account for 50% of the gram weight of the fabrics, and therefore common spacer fabrics are relatively heavy, particularly the spacer fabrics with large elasticity, and the gram weight is more than 400-500 GSM. Too bulky fabric limits the use scene and experience of the fabric itself, how can one make a high-elastic light-weight warp-knitted spacer fabric? At present, the solution method in the aspect mainly comprises the following steps: 1. the gram weight of the fabric is reduced by reducing the fineness of the yarns; 2. the density of the finished product is reduced;
with method 1, since the machine size of the multi-bar double needle bar warp knitting machine is below 32 needles, too thin yarn may break and face the problem of too narrow width of the greige cloth.
For the method 2, the density of the finished product is reduced, the cloth needs to be thinned during shaping, the spacer fabric is heavier, and the cloth needs to be pulled open only with great force during shaping, so that the shrinkage condition of the finished product is also worsened, and in addition, the elasticity of the material after thinning is reduced.
In summary, none of the above 2 weaving methods is ideal.
