Description
Technical field
Be combined for nonwoven fabric layer and film layer especially in regard to one kind make by the present invention on a kind of method of surface finish of fabric
Obtain the method and its finished product of compound fabric.
Background technology
It is existing to have coordinated the macromolecule to carry out Surface Machining for fabric with the progress of textile industry technology, for example：
(1) coating waste water technology or (2) pad pasting process technology etc., are lifted the effects such as enable intensity, the water proofing property of fabric.
As shown in Fig. 6 and Fig. 7 A and Fig. 7 B, be loaded into macromolecule masking liquid 70 in liquid holding groove 80 by coating waste water technology system, should
Macromolecule masking liquid 70 is that macromolecule is dissolved in into organic solvent to be formed, and then conveys fabric 51 with transmission wheel 90, and through carrying
Wheel 91 takes up the macromolecule masking liquid 70, the macromolecule masking liquid 70 is coated on fabric 51；Treat having in macromolecule masking liquid 70
After the volatilization of machine solvent and maturation, macromolecule layer 71 is able to be coated on the surface of fabric 51, to form the fabric once coating waste water
50 (as shown in Figure 7 A).
Because in the fabric 50 of the coated processing, macromolecule layer 71 is only coated on the surface of fabric 51 (such as Fig. 7 B institutes
Show), therefore cannot effectively lift the intensity of the fabric 50 of the coated processing；Need to use organic solvent during making again,
Therefore need additionally to wait organic solvent volatilization and maturation and elongate processing time in processing procedure；And part organic solvent may residue in this
The fabric 50 of coated processing, even causes negative impact to healthy and environment.

Liquid 62 is dissolved in organic solvent and is formed by macromolecule；A film 63 is affixed on the table that the fabric 61 scribbles hot melt adhesive solution 62 again
A pad pasting fabric 60 is formed behind face, and heated and pressurization.The pad pasting fabric 60 is thin with this by the fabric 61, hot melt adhesive layer 64
Film 63 is constituted, and the hot melt adhesive solution 62 on the surface that hot melt adhesive layer 64 is applied to fabric 61 by point is formed (as shown in Figure 9).
During the pad pasting fabric 60 is prepared, the hot melt adhesive solution 62 still needs to be dissolved in the middle of organic solvent, You Jirong
Agent may still residue in the pad pasting fabric 60, therefore can still produce negative impact, and the fabric 61 for healthy and environment
And the combination between the film 63 is mainly influenceed by hot melt adhesive layer 64 with the active force of the fabric 61 and the film 63, but the heat
Melting glue-line 64 can start aging with the time, therefore the pad pasting fabric 60 there are fabric 61 and film 63 and be used through long-time and peeled off
Problem.
