[0012] The utility model is further explained below in combination with the drawings and specific embodiment.

[0013] In combination Figure 1 Detailed description is made to the embodiment, a tear -resistant polyester warp -knitted fabric, comprising: wear -resistant layer 1, tear -resistant layer 2, moisture -conducting antibacterial layer 3 that compound in order, wear -resistant layer 1 is by wear -resistant yarn warp -knitted, tear -resistant layer 2 is full -width weft insertion warp -knitted organization, the full -width weft insertion warp -knitted organization includes warp -knitted organization and full -width weft, the warp -knitted organization is by polyester filament weaving, and the full -width weft is ultra high molecular weight polyethylene fiber filament, moisture -conducting antibacterial layer 3 is by GB1, GB2 two gill knitting, the GB1 is inserted into moisture -conducting yarn, and the GB2 is inserted into antibacterial yarn.

[0014] Specifically, wear -resistant layer 1, tear -resistant layer 2, moisture -conducting antibacterial layer 3 are compounded by array distribution's point -like hot melt type PU glue, and there is gap between adjacent point -like hot melt type PU glue, on the one hand guarantee the air permeability of fabric, on the other hand, the elasticity of knitted fabric still has between the adjacent point -like hot melt type PU glue of fabric.

[0015] Full -width weft insertion warp -knitted organization is the warp -knitted organization that the weft yarn with the length equal to the width of grey cloth is clamped between the loop main stem and the extension line, and the transverse stability of the fabric of this structure is high, and the size is not easy to change, when receiving external force tearing, the weft yarn of inlaying can share external force, prevents the expansion of tearing, is favorable to improve the tear -resistant performance of fabric whole, and the full -width weft of ultra high molecular weight polyethylene fiber is as the weft yarn, and the tear -resistant performance of fabric can be enhanced.

[0016] Specifically, the moisture-conducting and antibacterial layer 3 is a double-needle bar warp knitting structure with a portion of the guide bar being threaded, GB1 is full-threading and performs a flat-laid thread motion, and the laid thread code is 1-0 / 1-2 / / ; GB2 is two-threading and one-empty and performs a laid thread motion combining with warp pile and warp oblique, and the laid thread code is 3-4 / 2-1 / 3-4 / 1-0 / 2-3 / 1-0 / / ; in the absence of the extension line of GB2, the longitudinal line will deviate, forming eyelets, which is beneficial to the air permeability of the fabric.

[0017] Further, the wear-resistant yarn is a wear-resistant double-silk twisted and wrapped yarn. The core yarn of the wear-resistant double-silk twisted and wrapped yarn is a 18.5 tex combed cotton yarn, and two polyester filaments with different twist directions and same specifications are wrapped outside the core yarn. The specification of the polyester filaments is 38.9 dtex / 144F. The two polyester filaments form a net-like crossing and binding wrapped structure outside the core yarn, greatly enhancing the structural stability of the yarn. The unique net-like structure can effectively slow down the wear of the short fiber core yarn caused by external friction stress, which is helpful to improve the wear resistance of the yarn and the woven fabric.

The U-shaped cross-section polyester filament is a fiber produced by using a U-shaped spinneret, which belongs to a differentiated fiber. The U-shaped cross-section polyester filament has a cross-section similar to the English letter U. Because the fiber groove is deep, some fibers are even flattened, so that the groove disappears. The fiber with such a structure forms a fabric that is easy to produce more fine grooves, thereby forming more capillary channels, which is very beneficial to the transmission of moisture. In addition, the U-shaped cross-section polyester filament has a large specific surface area, and the fabric formed by the U-shaped cross-section polyester filament has good moisture-conducting and quick-drying properties.
