[0002] Clothing fabrics are the fundamental material element of clothing. With the innovative development of fiber technology, textile chemistry, and textile machinery, and the improvement of people's living standards, the consumption consciousness of clothing consumers has also changed significantly. In an era of pursuing ultimate comfort and high performance, the demand for diversified functional textile and clothing fabrics is becoming more and more widespread. Light outdoor leisure sports are gradually becoming popular, and frequent outdoor activities are subtly changing people's consumption habits.

[0003] Chemical fiber fabrics are often preferred for outdoor sportswear due to their excellent moisture absorption, quick drying, and versatility. Polyester fibers offer excellent wrinkle resistance and shape retention, along with high strength and elastic recovery. Polyester fibers also offer advantages such as light and chemical resistance, and are easy to wash and dry quickly.

[0004] However, some existing knitted fabrics only use polyester fiber materials for uniform loop weaving. This weaving composition makes the fiber structure of the fabric tightly arranged, which makes the fabric lack breathability and comfort. In addition, the same loop weaving also makes the surface texture of the fabric consistent, resulting in a lack of variation in the surface of the fabric. Therefore, this scheme proposes a polyamide polyester sheath-core composite fiber knitted fabric to solve the above problems. Utility Model Content

[0007] Preferably, the first route, the second route, the third route, the fourth route and the fifth route are all knitted in an AABB needle clock cycle arrangement.

[0008] Preferably, the A-version needles and B-version needles of the first route, the second route, the third route and the fourth route are all knitted into loops.

[0009] Preferably, the A version needles of the fifth route are used for loop knitting, and the B version needles of the fifth route are used for emerging knitting.

[0010] Preferably, the first route, the second route, the third route and the fourth route all use composite fiber yarns and elastic polyurethane fiber yarns, and the fifth route usually uses composite fiber yarns.

[0011] Preferably, the composite fiber yarn is made of 70D / 48F semi-gloss polyamide polyester sheath-core composite fiber.

[0012] Preferably, the composite fiber yarn comprises a sheath layer and a core layer, the sheath layer is made of polyamide fiber, and the core layer is made of polyester fiber.

[0013] Preferably, the elastic polyurethane fiber is 20D polyurethane lycra elastic fiber.

[0014] The technical effects and advantages of this utility model are:

[0015] The knitted fabric of the utility model adopts a 5-way one-cycle knitting structure to form the fabric, wherein the first, second, third and fourth ways are synchronously knitted into loops through the same yarn mouth, while the fifth way is fed with yarn separately and knitted into loops in two working positions.

BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 This is a schematic diagram of the fabric structure of the present invention.

[0017] Figure 2 This is the weaving pattern of the fabric of this utility model.

[0018] In the figure: 1, first route; 2, second route; 3, third route; 4, fourth route; 5, fifth route. DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] The utility model provides Figure 1-2The polyamide polyester sheath core composite fiber knitted fabric shown is weft-knitted by multiple groups of knitted tissues, each group of knitted tissues has 5 routes in one cycle, and the 5 routes include the first route 1, the second route 2, the third route 3, the fourth route 4 and the fifth route 5. The first route 1, the second route 2, the third route 3 and the fourth route 4 are synchronously woven into loops through the same yarn mouth, and the fifth route 5 is fed with yarn separately and woven into loops in two working positions.

[0021] It should be noted that the yarn of this scheme is weft knitted, and the weaving process adopts 5-way one cycle, and a 32-needle weft knitting single-sided circular knitting machine is selected. The first route 1, the second route 2, the third route 3 and the fourth route 4 select the composite material and elastic polyurethane fiber to be woven into loops synchronously at the same yarn mouth using the covering weaving process. The fifth route 5 selects the composite material to be fed into the yarn separately to form a loop, and the two working positions are woven into loops separately. The purpose is to design a fabric that is both tight and elastic, comfortable and breathable, and can also change the casual and fashionable sense of the entire style of the fabric, and enhance the diversified needs of the fabric in clothing applications.

[0022] Specifically, the first route 1, the second route 2, the third route 3, the fourth route 4 and the fifth route 5 are all knitted in an AABB needle clock cycle arrangement;

[0023] The A version needles and B version needles of the first route 1, the second route 2, the third route 3 and the fourth route 4 are all knitted in loops, the A version needles of the fifth route 5 are knitted in loops, and the B version needles of the fifth route 5 are knitted in floating patterns.

[0024] It should be noted that the reference Figure 1 As shown, the black track coils of the first route 1, the second route 2, the third route 3 and the fourth route 4 are shown as the A version needle and the B version needle are woven with a loop forming process. The yarn is selected from 70D / 48F semi-gloss polyamide polyester sheath-core composite fiber and 20D polyurethane lycra stretch fiber material. The sheath-core composite fiber material and polyurethane lycra are synchronously woven and formed at the same yarn mouth with a covering weaving process structure in weaving, which enhances the soft and elastic performance of the finished style of the entire fabric and enhances the wearing comfort of the clothing fabric. The modified semi-gloss polyamide fiber material has fiber strength, moisture absorption and wear resistance. The modified polyester fiber material has moisture absorption, quick drying, wrinkle resistance and shape retention. The semi-gloss modified polyamide fiber material is selected to cover the semi-gloss modified polyester with a sheath-core structure. The composite fiber material can retain the various excellent properties of different fibers. The overall fabric is skin-friendly and soft, and has the straight and bony feel of the polyester core material. It can be widely used in T-shirts, POLO and other spring and summer clothing fabrics.

[0025] The fifth route 5 is knitted with two different needles in AABB cyclic arrangement, such as Figure 1As shown, the A version of the needle shown by the black dotted track coil is woven with a looping process, and the B version of the needle shown by the black solid line is woven with an emerging process. The yarn of this route is preferably 70D / 48F semi-gloss polyamide polyester sheath-core composite fiber. The design of this process structure can make the fabric style present a uniform mesh micro-texture effect, which helps to enhance the comfort and breathability of the fabric.

[0026] Furthermore, the first route 1 , the second route 2 , the third route 3 and the fourth route 4 all use composite fiber yarns and elastic polyurethane fiber yarns, and the fifth route 5 often uses composite fiber yarns.

[0027] Furthermore, the composite fiber yarn adopts 70D / 48F semi-gloss polyamide polyester sheath-core composite fiber. The composite fiber yarn includes a sheath layer and a core layer. The sheath layer adopts polyamide fiber, the core layer adopts polyester fiber, and the elastic polyurethane fiber adopts 20D polyurethane Lycra elastic fiber.

[0028] It should be noted that although polyamide fiber material has good dyeing and moisture absorption properties, the fiber itself has a low modulus, and the knitted fabric produced is too soft and sticky, and lacks silhouette for T-shirts and POLO shirts. The polyester fiber material itself has relatively poor moisture absorption and dyeing properties, but the fiber itself has a high modulus, and the knitted fabric produced has the stiffness that T-shirts and POLO shirts should have. Therefore, this research design will use polyester fiber material with a higher modulus as the core material, and polyamide fiber material with better dyeing and moisture absorption properties as the surface layer of the core-skin composite yarn. The yarn produced in this way can well meet the design choices in color and multi-function in the application of knitted fabrics.
