Description
Technical Field
The invention relates to the field of warp-knitted spacer fabrics, in particular to a warp-knitted spacer fabric with a curved surface structure and a knitting method thereof.
Background
The warp-knitted spacer fabric is a double-faced fabric tissue with a unique three-dimensional hollow structure produced on a double-needle bed warp knitting machine and consists of two surface fabric layers which are independent from each other and a spacer yarn layer which plays a role in connection and support in the middle. The upper and lower surface fabric layers of the warp-knitted spacer fabric can be knitted into a compact structure, a jacquard structure, a mesh or mesh and other structures, and the spacer yarns in the middle layer play a role in supporting the two surface layers, so that monofilaments with higher bending rigidity, such as polyester monofilaments and polyamide monofilaments, are generally adopted.
Warp-knitted spacer fabrics are widely applied to the fields of home textiles, clothing, medical protection, transportation and the like due to excellent air permeability, moisture permeability, pressure-release buffering performance and the like. Meanwhile, the warp-knitted spacer fabric can also be used for reinforcement of composite materials, and is light in weight, strong in designability and good in integrity, so that the warp-knitted spacer fabric is widely applied to the fields of aerospace, buildings, ships and the like.
The existing warp-knitted spacer fabric weaving technology can only be carried out on one plane, so that the shape of the warp-knitted spacer fabric is limited, and the warp-knitted spacer fabric cannot be directly applied to the field with special requirements on the shape of the warp-knitted spacer fabric. Such as cups, helmets and other products made of warp-knitted spacer fabrics at present are all formed by mould pressing or cutting and sewing. The compression molding can cause serious mechanical damage to fibers in the fabric and cause the loss of the special performance of the warp-knitted spacer fabric; the cutting and sewing molding not only wastes raw materials, but also requires high technique and a large amount of time. Therefore, the research on a warp-knitted spacer fabric with a curved surface structure and a weaving method thereof become a technical problem to be solved in the field.

Further, when a curved surface structure which protrudes in the direction away from the other warp knitted fabric layer is formed on only one warp knitted fabric layer at the same position, the warp feeding amount of the spacing yarns of the part is increased; when a curved surface structure recessed in a direction close to the other warp knitted fabric layer is formed only on one warp knitted fabric layer at the same position, the let-off amount of the spacer yarn at that portion is reduced.
Further, when two warp-knitted fabric layers at the same position form a curved surface structure protruding towards the direction far away from the other warp-knitted fabric layer, the warp feeding amount of the spacing yarns at the part is increased; when two warp-knitted fabric layers at the same position form a curved surface structure which is concave towards the direction close to the other warp-knitted fabric layer, the warp feeding amount of the spacing yarns at the part is reduced.
