Description

Technical Field

[0001] The utility model relates to the technical field of textiles, and more specifically refers to a knitted composite jacket fabric. Background Art

[0002] As people's understanding of sports and leisure continues to deepen, the definition of outdoor sports has gradually spread from professional hobbies and competitive sports to non-professional leisure sports. The outdoor sports environment is changeable, and the external climate changes rapidly. As the first interface between the human body and the outside world, the jacket is the first layer of protection for the human body. The design and development of jacket fabrics cater to the needs of the public. In addition to the basic functions of windproof, rainproof and wear-resistant, it also pays more attention to the comfort requirements of lightness, moisture absorption and sweat permeability.

[0003] The Chinese patent with the authorization announcement number CN 216400838U discloses a high-density polyester-nylon composite fiber cloth, including a polyester-nylon fabric layer, and a waterproof and breathable membrane compositely arranged on one side of the polyester-nylon fabric layer; the polyester-nylon fabric layer is formed by interweaving the warp yarn and the weft yarn with a twill weave or a satin weave; the warp yarn includes a cut-resistant coated yarn, and the cut-resistant coated yarn includes a core yarn and a coated yarn; the core yarn is an ultra-high molecular weight polyethylene filament, and the coated yarn is a nylon filament; the weft yarn is a strand of polyester-nylon composite yarn and an ultra-high molecular weight polyethylene filament twisted together. Although the warp yarn and the weft yarn of the patent both contain ultra-high molecular weight polyethylene filaments, which can significantly improve the cut-resistant ability of the entire fabric, the polyester-nylon fabric is a woven fabric formed by interweaving the warp yarn and the weft yarn with a twill weave or a satin weave, and the woven fabric is relatively stiff and uncomfortable to wear.

[0004] In addition, ultra-high molecular weight polyethylene filaments are usually white, difficult to dye, and expensive. To this end, we provide a composite jacket fabric with an ultra-high molecular weight PE / nylon blended knitted fabric as the surface layer. On the one hand, the fabric pattern is designed through blending, and on the other hand, the ultra-high molecular weight PE on the surface of the fabric makes the fabric have the excellent properties of PE while reducing the cost. Utility Model Content

The membrane layer is pressed and bonded to the outer surface of the lining layer, and the surface layer is pressed and bonded to the outer surface of the membrane layer, forming a three-layer composite fabric.

[0008] Preferably, the base fabric of the surface layer has a specification of 100D / 60F+FDY 40D / 34F and a width of 170 cm.

[0009] Preferably, the weft knitted fabric is woven from colored yarns formed by twisting ultra-high molecular weight polyethylene fibers and colored nylon fibers.

[0010] Preferably, the outer surface of the three-layer composite fabric is also provided with a waterproof finishing layer.

[0011] Preferably, the polyurethane microporous membrane is a high-permeability thickened membrane PPU with a moisture permeability of 20,000 and a gram weight of 16 g / m2.

[0012] Preferably, the polyester fabric uses polyester as the base fabric, and the specification is DTY SD 100D / 36F+DTY SD 100D / 144F.

[0013] From the above description of the structure of the utility model, it can be seen that compared with the prior art, the beneficial effects produced by the utility model are:

[0014] 1. The jacket fabric of the utility model adopts a weft-knitted fabric woven from filament yarns twisted with ultra-high molecular weight polyethylene fibers and nylon fibers as the base fabric of the surface layer. While ensuring that the fabric has the function of resisting the scratches of stones and sharp branches, and has good air permeability and heat dissipation, it also ensures the softness and good wear resistance of the fabric, ensuring the comfort of human movement.

[0015] 2. The jacket fabric of the utility model, the weft knitted fabric of the surface base cloth is woven with colored yarns formed by twisting ultra-high molecular weight polyethylene fibers and nylon fibers, and the desired design fabric color can be obtained, solving the problem that ultra-high molecular weight polyethylene fibers are difficult to dye and expensive.

[0020] The specific implementation of the present invention is described below with reference to the accompanying drawings. In order to fully understand the present invention, many details are described below, but for those skilled in the art, the present invention can be implemented without these details.

[0021] Reference Figure 1 and Figure 2 The utility model is a knitted composite jacket fabric, comprising a surface layer 10, a film layer 20 and a lining layer 30. The film layer 20 is laminated to the outer surface of the lining layer 30, and the surface layer 10 is laminated to the outer surface of the film layer 20, forming a three-layer composite fabric 1.

[0022] Reference Figure 2 The surface layer 10 is made of ultra-high molecular weight PE / nylon fabric as the base fabric, with specifications of DTY SD 100D / 36F+DTY SD 100D / 144F and a width of 170cm. The base fabric is made of filament yarn twisted with ultra-high molecular weight polyethylene fiber 101 and nylon fiber 102 (refer to Figure 3 ) is a weft knitted fabric woven from a

[0023] Since the ultra-high molecular weight polyethylene fiber 101 is white, it is difficult to dye. Therefore, the weft knitted fabric shown in this embodiment is woven from colored yarns twisted from the ultra-high molecular weight polyethylene fiber 101 and colored nylon fibers.

[0024] This embodiment specifically uses four raw material specifications, namely: 140D / 94F PE / N S600, 175D / 96F PE / T Z600, 175D / 96F PE / T S600, 175D / 96F PE / T Z600. The weft knitting manufacturing process is shown in the following table.

[0025]

[0026] Reference Figure 2 The above-mentioned film layer 20 is a polyurethane microporous film, which is a high-permeability thickened film PPU, with a moisture permeability of 20,000 and a gram weight of 16 grams per square meter. The film pressing and laminating process is as follows: fabric preparation → softening treatment → steam pre-shrinking film → diamond-shaped point rubber roller laminating PUU film → maturation → round-point rubber roller laminating knitted fabric → maturation → waterproofing → steaming → finished product.

[0027] Reference Figure 2 The outer surface of the three-layer composite fabric is also provided with a waterproof finishing layer 40. Specifically, the fluorine-free waterproof agent ECO is used, and the waterproof finishing process is: one dip and one roll (liquid carrying rate 50-60%) → pre-baking (90℃, 3 min) → baking (100-180℃, 30-90s) → moisture regain to be tested.

[0028] Through the above process, a breathable jacket fabric is obtained. According to GB / T 8629-2017, the moisture permeability of the fabric is tested, the washing procedure is 4N, and after 3 cycles of washing, the hydrostatic pressure of the fabric is greater than 200 kpa, and the transparency is 3.48*10 3 .

[0029] The above is only a specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
