Description

Technical Field

[0001] The utility model relates to the technical field of textile manufacturing, and particularly relates to a multi-layer composite base fabric. Background Art

[0002] A base fabric refers to the natural-colored cotton cloth for dyeing and printing processing, which is an unprocessed textile and is the first step in textile production. In industry, the base fabric generally refers to cloth, or laminated base fabric, sized base fabric, etc.; the uses of the base fabric are very extensive, and it can be used to make various textiles, such as clothes, bedding, curtains, tablecloths, and so on;

[0003] In actual production, due to the single composition of the base fabric, the functions it has are relatively single, and it is not practical and reliable enough. By compounding cloth layers with different characteristics with the inner core, various practical functions can be given to the base fabric. For this reason, we propose a multi-layer composite base fabric. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a multi-layer composite base fabric. The braided inner core made of intertwined strands gives the base fabric better elasticity and tensile properties. By arranging a heat-insulating layer, a wear-resistant layer and a waterproof coating on both sides of the braided inner core, through multi-layer composite materials, while the base fabric has good elasticity, it can also have heat-insulating effect, waterproof and wear-resistant properties, and is more practical and reliable; in addition, through the cooperation of the fine ventilation holes and the thick braided holes generated by braiding, good ventilation performance can be provided for the base fabric, and the problems in the background art can be effectively solved.

[0005] To achieve the above object, the utility model provides the following technical scheme: a multi-layer composite base fabric, including a braided inner core, a wrapping layer, a heat-insulating layer, a wear-resistant layer and a waterproof coating. The braided inner core is arranged in the middle layer of the base fabric and is formed by interweaving horizontal and vertical strands. The outer side of the braided inner core is surrounded and covered with a wrapping layer. A wear-resistant layer is arranged on one side of the wrapping layer, and a layer of waterproof coating is brushed on the upper end of the wear-resistant layer. A heat-insulating layer is arranged on the surface of the wrapping layer and away from the wear-resistant layer.

[0006] The braided inner core made of intertwined strands gives the base fabric better elasticity and tensile properties. The annularly wound wrapping layer completely covers the braided inner core and provides a carrier for the outer composite layer. The heat-insulating layer and the wear-resistant layer are respectively arranged on both sides of the wrapping layer. The wear-resistant layer faces the outside and has higher wear-resistant performance. The heat-insulating layer is close to the human body and can provide better heat-insulating effect. The waterproof coating makes the base fabric have certain waterproof performance; through multi-layer composite materials, while the base fabric has good elasticity, it can also have heat-insulating effect, waterproof and wear-resistant properties, and is more practical and reliable.

[0007] Furthermore, it also includes fixed leads. AB glue is brushed on both the upper and lower surfaces of the braided inner core. The wrapping layer is bonded and fixed to the braided inner core through the AB glue. A plurality of fixed leads are equidistantly penetrated through the surface of the base fabric. The heat-insulating layer and the wear-resistant layer are fixed to the braided inner core of the intermediate layer through the fixed leads. The fixed leads are used to fix the heat-insulating layer and the wear-resistant layer to the intermediate layer of the base fabric, so that each composite layer and the intermediate layer jointly form a complete base fabric as a whole.

[0008] Furthermore, it also includes thick braided holes and fine ventilation holes. Uniformly spaced thick braided holes are left inside the braided inner core. Fine ventilation holes are evenly formed on the surface of the wear-resistant layer. The fine ventilation holes sequentially penetrate through the waterproof coating and the wear-resistant layer and are connected to the thick braided holes. Through the cooperation of the formed fine ventilation holes and the thick braided holes produced by braiding, good ventilation performance can be provided for the base fabric.

[0009] Furthermore, the heat-insulating layer is made of cotton fiber material. The heat-insulating layer made of cotton fiber is more suitable for wearing close to the body.

[0010] Furthermore, the wear-resistant layer is made of polyester fiber. The wear-resistant layer made of polyester fiber has good wear resistance.

[0011] Furthermore, the strands of the braided inner core and the wrapping layer are both made of natural color cotton thread material, which is convenient for subsequent coloring processes such as printing and dyeing.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: The present multi-layer composite base fabric has the following advantages:

[0013] 1. The braided inner core made of interlaced strands enables the base fabric to have good elasticity and tensile properties.

By providing a heat-insulating layer, a wear-resistant layer and a waterproof coating on both sides of the braided inner core, through multi-layer composite materials, while the base fabric has good elasticity, it can also have heat-insulating effects, waterproof and wear-resistant properties, making it more practical and reliable;

[0014] 2. Fine ventilation holes are evenly formed on the surface of the wear-resistant layer. The fine ventilation holes sequentially penetrate through the waterproof coating and the wear-resistant layer and are connected to the thick braided holes. Through the cooperation of the formed fine ventilation holes and the thick braided holes produced by braiding, good ventilation performance can be provided for the base fabric;

[0015] 3. In the present utility model, the braided inner core made of intertwined strands endows the base fabric with good elasticity and tensile properties.
