Description

Composite fabric and manufacturing method thereof

The present invention relates to a surface processing method of a fabric, and particularly to a method of compounding a woven fabric layer and a film layer to obtain a composite fabric and a finished product thereof.

With the advancement of the textile industry technology, currently, it is possible to cooperate with polymers to perform surface processing on fabrics, such as: (1) coating processing technology or (2) film processing technology, etc., so that the strength and waterproofness of the fabric can be improved.

As shown in FIG. 6 and FIG. 7, the coating processing technology is to load a polymer coating liquid 70 in a liquid storage tank 80. The polymer coating liquid 70 is formed by dissolving a polymer in an organic solvent, and then a transfer wheel 90 is used. The fabric 51 is conveyed, and the polymer coating liquid 70 is taken up by the carrying wheel 91, so that the polymer coating liquid 70 is coated on the fabric 51; after the organic solvent in the polymer coating liquid 70 is volatilized and matured, the polymer The layer 71 is capable of covering the surface of the fabric 51 to form a coated fabric 50 (as shown in FIG. 7).

In the coated fabric 50, the polymer layer 71 only covers the surface of the fabric 51 (as shown in FIG. 7), so the strength of the coated fabric 50 cannot be effectively improved; Organic solvents are used in the process, so it is necessary to wait for the organic solvents to evaporate and mature in the process to lengthen the process time; and some organic solvents may remain in the coated fabric 50, which may even have a negative impact on health and the environment. .

As shown in FIG. 8 and FIG. 9, the film processing technology is to spot-coat the surface of the fabric 61 with a hot melt solution 62, which is formed by dissolving a polymer in an organic solvent; The fabric 61 is coated with a surface of the hot melt adhesive solution 62, and forms a film fabric 60 after being heated and pressed. The film fabric 60 is composed of the fabric 61, a hot-melt adhesive layer 64, and the film 63. The hot-melt adhesive layer 64 is formed by a hot-melt adhesive solution 62 that is spot-coated on the surface of the fabric 61 (see FIG. 9). As shown).

In the process of preparing the film fabric 60, the hot melt solution 62 still needs to be dissolved in an organic solvent, and the organic solvent may still remain in the film fabric 60, so it will still have a negative impact on health and the environment, and the The bonding between the fabric 61 and the film 63 is mainly affected by the forces of the hot-melt adhesive layer 64, the fabric 61 and the film 63, but the hot-melt adhesive layer 64 will begin to age with time, so the film fabric 60 exists There is a problem that the fabric 61 and the film 63 are peeled off after a long period of use.

The purpose of this creation is to improve the current surface processing methods of fabrics, to avoid the use of organic solvents, and to increase the strength of the fabrics after processing.
