Problems solved by technology

[0002] In the prior art, the warp-knitted polyester fabrics used in clothing, toys, and bedding are mainly made of polyester superfine fibers, polyester DTY yarns or polyester-nylon composite yarns. The fabrics woven from such raw materials have the following defects: One is that the firmness of the fabric is not ideal, because this kind of fabric is generally only made of the surface weave and the bottom weave along the radial direction and simultaneously lapped yarns on the knitting needles, so the gap between the surface weave and the bottom weave The drafting tension is difficult to guarantee, which affects the tensile strength of the fabric, and the durability requirements cannot be satisfied; the second is poor gloss, because polyester microfiber, polyester DTY yarn and polyester nylon composite yarn are all semi-gloss or matte. The raw material has a weak refraction degree to light, and cannot achieve a bright effect, and cannot meet the gloss requirements of high-end clothing, toys, and bedding fabrics; third, the elasticity is not ideal, because this type of fabric only uses polyester with surface tissue and bottom tissue. Superfine fiber, polyester DTY, nylon-polyester composite yarn and other raw materials cannot be added with elastic fibers such as spandex due to the limitations of the loom during the weaving process, so such fabrics do not have stretchability, extensibility and recovery.
The disadvantage of this method is that there is a phenomenon of lodging on the suede surface, and there are inverted and smooth wool. Because the refractive index of the inverted wool and smooth wool is different for the color, the color and luster of the entire cloth surface is not uniform, the suede surface is not smooth, and the hand feel is not enough. full

Abstract

The invention relates to a warp-knitting polyester fabric and a processing method thereof, which belong to the fields of a polyester fibre product and a processing technique thereof. The warp-knitting polyester facing material comprises a surface layer tissue, a bottom layer tissue and an inner layer tissue positioned between the surface layer tissue and the bottom layer tissue, wherein the used raw material of the surface layer tissue is FDY bright yarn of 50D / 36F; the used raw material of the bottom layer tissue is spandex yarn of 40D; and the used raw material of the inner layer tissue is FDY bright yarn of 50D / 36F or 75D / 36F. Because the invention adopts the raw materials of the surface layer tissue, the inner layer tissue and the bottom layer tissue to form the warp-knitting polyester fabric, favorable pull tension exists between the surface layer tissue and the bottom layer tissue, and the tensile strength of the facing material is ensured, so that the warp-knitting polyester fabric has durability; the raw materials of the surface layer tissue and the inner layer tissue adopt the bright yarn, so that a beautiful feel can be presented; the bottom layer tissue adopts the spandex yarn, so that elasticity can be presented; and the technological steps adopted by the method can prevent floss faces from generating the phenomena of wool collapse and wool reversal, so that flosses have strong upright feel, and the floss faces are plump.
