Description

Elastic double-layer warp-knitted fabric

Technical Field

The utility model relates to an elastic double-layer warp-knitted fabric.

Background

At present, the chinese patent application No.: CN201520931472.9 discloses a PVC screen cloth, including multiunit warp and multiunit weft, arbitrary a set of warp in the multiunit warp includes first warp, second warp, third warp, fourth warp, fifth warp, sixth warp, seventh warp and eighth warp, arbitrary a set of weft in the multiunit weft includes first weft, second weft, third weft, fourth weft, fifth weft, sixth weft, seventh weft and eighth weft, arbitrary a set of warp is perpendicular to interweave with arbitrary a set of weft, and warp is connected with the contact of crossing of weft.

Although the air permeability-improving fabric is simple in structure and strong in practicability, and can be attached to other surfaces more easily, in the actual use process, the problems of poor buffering capacity and insufficient elasticity exist due to the fact that only a single woven layer exists, meanwhile, the air permeability-improving fabric is dense, and the air permeability cannot be improved further while the compact structure is guaranteed.

SUMMERY OF THE UTILITY MODEL

Therefore, in order to solve the problems, the utility model provides an elastic double-layer warp-knitted fabric, which solves the problems of poor cushioning capability, insufficient air permeability and the like when the existing fabric is used as a cushion.

In a further improvement, the supporting block is provided with an upper surface which is in an arc-shaped bulge, and a plurality of grooves are arranged on the upper surface of the supporting block at intervals.

In a further improvement, a plurality of vent grooves are formed in the lower surface of the supporting block between two adjacent grooves.

In a further improvement, the upper surface of the supporting block is provided with a plurality of vent holes communicated with the vent grooves.

The improved structure is characterized in that the surface layer and the bottom layer are both formed by weaving and warp knitting of mixed twisted yarns, and the mixed twisted yarns are formed by mixing and twisting spandex fibers and polyester fibers in a ratio of 1: 1.

In a further improvement, the surface layer is knitted through a fourteen-needle process of a double-needle warp knitting machine, and the bottom layer is knitted through a twenty-eight-needle process of the double-needle warp knitting machine.

By adopting the technical scheme, the utility model has the beneficial effects that: according to the utility model, the supporting block made of hard cotton is adopted between the surface layer and the bottom layer, and the hard cotton has good air permeability and deformation resilience rate, so that the air guide and heat dissipation are facilitated, and the buffering performance is improved; meanwhile, the waterproof coating has the characteristics of water resistance, moisture resistance, aging resistance, wear resistance, water washing resistance and the like; the supporting block is provided with the groove, the vent groove and the vent hole, so that heat dissipation is facilitated, the comfort of the mattress is further improved when the mattress is used as the mattress, and meanwhile, a massage effect can be achieved to a certain extent; the surface layer and the bottom layer are woven and warp-knitted by adopting the mixed twisted yarns, wherein the spandex fibers have excellent elasticity, sweat resistance, wear resistance, comfort and air permeability, the polyester fibers are woven, the fabric is firm and durable, the elasticity is good, and the fabric is not easy to deform; the surface layer is knitted through a fourteen-needle process of a double-needle warp knitting machine, the bottom layer is knitted through a twenty-eight-needle process of the double-needle warp knitting machine, compared with the twenty-eight-needle process, a fabric knitted through the fourteen-needle process is more compact and not prone to deformation, and the surface layer is knitted through the fourteen-needle process and is made to be more compact and not prone to deformation.
