Description

Method for making fabric with hook and loop function

The present invention relates to a method of making a fabric, in particular to a method of making a fabric with a hook-and-loop fastening function.

According to the conventional self-glue fabric, the two sides of the fabric have a loop structure and a hook structure respectively. The loop structure is opened by composite spinning to form a loop with ultra-fine fibers, and the hook structure is Hooks are formed by singeing hot-melt fibers. The loop structure and the hook structure can be hooked together to meet the needs of quick fastening of clothing, protective equipment or accessories.

However, the fastening effect of the self-gluing fabric is limited to when the loop structure and the hook structure are hooked together. The fastening effect will be lost on other fabrics, reducing the scope of use, and those who are accustomed to using self-gluing fabrics Fabric materials and manufacturing processes have great limitations. Therefore, after observing the above shortcomings, the inventor of this case believed that there was a need to improve the existing manufacturing method of fabrics with hook and loop functions, and thus the present invention was born.

The purpose of the present invention is to provide a method for making a fabric with a hook-and-loop function, which can increase the hook-and-loop effect and friction of the hook surface structure, and further improve the hook-and-loop effect and friction when overlapping the terry cloth torus structure. .

In order to achieve the above object, the invention provides a method for making a fabric with a hook-and-loop fastening function, which includes the following steps:

Material preparation step: prepare a base fabric with a plurality of hairs on one side; heating step: heat the surface of the base fabric so that part of the plurality of hairs are heated into a hook surface structure; strengthening step: heat Each hook surface structure of the base fabric is covered with a reinforcement layer; the step of strengthening the shaping is: shaping the reinforcement layer of each hook surface structure to complete the fabric with a hook-and-loop function.

The manufacturing method of the fabric with hook and loop function provided by the present invention uses heating steps, strengthening steps and strengthening shaping steps to make each hairy part of the hook and loop fabric have the hook surface structure, and these hook surface structures are covered The reinforcement layer increases the hooking effect and friction of the hook surface structure, and further improves the hooking effect and friction when overlapping with the terry cloth torus structure.

Please refer to Figure 1, which is a flow chart of a preferred embodiment of the present invention. It discloses a method of making a fabric with a hook-and-loop function. The fabric 100 with a hook-and-loop function can be hooked on A fiber knitted fabric. The fiber knitted fabric is a knitted fiber knitted fabric. The fiber knitted fabric has an annular structure. In the embodiment of the present invention, the fiber knitted fabric is a terry cloth. The weight of the fiber knitted fabric is between meters square. The weight is preferably 120 grams to 350 grams. It can be used as the fleece or base surface of the Velcro fabric. It includes the following steps:

Material preparation step: prepare a base fabric 10, which is a woven or knitted fabric. The material of the base fabric 10 can be selected from nylon, polyester fiber, nylon polyester fiber blend, long fiber, short fiber. fiber or long fiber and short fiber blend, the weight of the base fabric 10 is preferably between 150 g and 350 g per square meter. In the embodiment of the present invention, the base fabric 10 is selected from a conventional pile embryo currently available on the market. Cloth or colored cloth fiber braid 200, such as velvet or velvet, etc., and one side of the base fabric 10 has a plurality of hairs 11, as shown in Figure 2, in the embodiment of the present invention, the plurality of hairs 11 It is formed by the base fabric 10 through raising, brushing or shearing processing, and the length of the plurality of hairs 11 is between 0.1 mm~2.5 mm, preferably 0.2 mm~1.8 mm.

Coating step: Coating the plurality of hairs 11 of the base fabric 10 with a coating layer 12. In the embodiment of the present invention, the coating layer 12 is a water-dispersed resin composition that is compatible with water. For example, water-based polyurethane resin, water-based acrylic resin or ethylene-vinyl acetate resin. The coating layer 12 is prepared in an appropriate proportion and undergoes a bridging reaction to become a synthetic resin. The coating layer 12 is then diluted with water to an appropriate proportion of 1 to 50 WT %. The layer 12 is coated with a plurality of hairs 11 or the base fabric 10 is impregnated, so that each hairy 11 of the base fabric 10 is covered with the coating layer 12 .

The reinforcement layer 14 is the resin, and the reinforcement layer 14 is a water-dispersed type that is compatible with water. The resin composition, such as water-based polyurethane resin, water-based acrylic resin or ethylene-vinyl acetate resin, is prepared in an appropriate proportion and undergoes a cross-linking reaction to form a synthetic resin. It is then diluted with water to an appropriate proportion of 1 to 50 WT %, and then the reinforced layer 14 is used. Use a roller to coat the surface of the hook surface structure 13 or impregnate the base fabric 10, so that the hook surface structure 13 is covered with the reinforcement layer 14, wherein the reinforcement layer 14 can be adjusted by adjusting the ratio of resin and water to adjust the adhesive function. Fabric hardness 100.

Strengthening the shaping step: pass the hook surface structure 13 of the base fabric 10 through the arranging equipment to eliminate the burring phenomenon of the hook surface structure 13, and then use the shaping equipment to clean each hook surface structure 13 covered with the reinforcement layer 14 Heating, drying and shaping are carried out, as shown in Figure 5, so that the reinforcement layer 14 can strengthen the hook surface structure 13, increase the hooking effect and friction of the hook surface structure 13, and thereby improve the strength when overlapping with the terry cloth ring structure. The hooking effect and friction can be increased several times, so that the hooking effect and friction of the hook surface structure 13 can partially replace the function of Velcro felt, and can be applied to products such as protective gear, clothing, shoe materials, or hat materials. .
