Detailed Description
In order to explain technical contents, achieved objects, and effects of the present invention in detail, the following description is made with reference to the accompanying drawings in combination with the embodiments.
The most key concept of the invention is as follows: the jacquard part is designed into a structure that the middle weft yarn layer and the surface weft yarn layer are woven in a mixed mode, so that the middle weft yarn layer is partially exposed out of the surface weft yarn layer.
Referring to fig. 1, the invention relates to a double-layer mixed weaving sandwich weft fabric, which comprises a sandwich weft fabric body 1 and a jacquard part 2 arranged on the sandwich weft fabric body 1, wherein the sandwich weft fabric body 1 comprises a surface weft yarn layer 11, a middle weft yarn layer 12 and an inner weft yarn layer 13 which are sequentially arranged from outside to inside, the middle weft yarn layer 12 is in a vertical weaving form, and the jacquard part 2 comprises a mixed weaving layer 21 formed by mixing the middle weft yarn layer 12 and the surface weft yarn layer 11.
Among the above-mentioned double-deck sandwich weft knitting cloth structure of weaving in mixture, through the structure of weaving in mixture with jacquard portion 2 for middle woof layer 12 and surface woof layer 11, make middle woof layer 12 part expose in the surface of surface woof layer 11, utilize the material difference of the yarn of middle woof layer and surface woof layer itself to realize the contrast ratio of jacquard portion and other regions on surface woof layer, can effectively shorten the preparation flow, save cost, and can adjust jacquard portion thickness in a flexible way, realize sandwich weft knitting cloth's whole gas permeability, warmth retention property and protectiveness simultaneously. Because the mixed jacquard part and the sandwich weft-knitted fabric body can be knitted at one time without being respectively knitted, the structure that any mixed jacquard part is staggered with the sandwich weft-knitted fabric body can be knitted at one time on one piece of fabric, and therefore any jacquard shape can be processed efficiently.
Further, in the above double-layer mixed-knitting sandwich weft-knitted fabric structure, the inner weft layer 13 covers the inner surface of the jacquard part 2.
In the structure, the jacquard effect cannot be seen from the inner surface of the sandwich weft knitted fabric, so that the front side and the back side of the fabric can be distinguished conveniently.
Further, in the double-layer mixed-knitting sandwich weft-knitted fabric structure, the linear density of the surface weft layer 11 is 30-150D or 30-60S.
Further, in the above double-layer hybrid sandwich weft-knitted fabric structure, the linear density of the middle weft layer 12 is 30-150D.
Further, in the double-layer mixed-knitting sandwich weft-knitted fabric structure, the linear density of the lining weft layer 13 is 30-150D or 30-60S.

The yarn has bright luster, and can improve visual aesthetic feeling of the surface when being used for making clothes.
Further, in the above double-layer hybrid sandwich weft-knitted fabric structure, the middle weft layer 12 is made of polyester or nylon monofilament.
The middle layer is made of terylene or chinlon monofilament, which can increase the thickness of the cloth and give the functions of shock absorption, friction prevention and ventilation by using the elasticity and the vertical weaving shape of the fiber.
Further, in the above double-layer hybrid sandwich weft-knitted fabric structure, the inner weft layer 13 is made of polyester, nylon, acrylic, polypropylene, vinylon, cotton yarn, spandex or a combination of any two of them.
Further, in the above double-layer mixed-knitting sandwich weft-knitted fabric structure, the thickness of the mixed-knitting layer 21 is smaller than the overlapping thickness of the surface weft layer 11 and the middle weft layer 12.
As can be seen from the above description, the thickness of the mixed-knitting layer 21 is smaller than the thickness of the surface weft layer 11 and the middle weft layer 12, so that the thickness of the mixed-knitting jacquard part is smaller than the thickness of the weft fabric body, the jacquard part and the weft fabric body are naturally interlaced to form various three-dimensional patterns, and the air permeability of the jacquard part can be increased.
Further, in the above double-layer hybrid sandwich weft fabric structure, the linear density of the surface weft layer is 75D, the linear density of the inner weft layer is 75D, and the linear density of the middle weft layer is 40D.
