Description

Firstly combined with the off-shaped carrier coating and replacement of functional knitted fabric processing law

The invention relates to a fabric coating processing method, in particular to a knitting cloth coating processing method.

The general fabric 9 is woven from fibers and is roughly classified into a woven fabric 91 (see Fig. 1) and a knit fabric (see Fig. 2). Among them, the woven fabric 91 is interwoven by two sets of yarns (warp yarn 911 and weft yarn 912) (see Fig. 1). The warp yarns 911 are fastened to the loom, parallel to the fabric 913, and the weft yarns 912 are transversely interspersed between the warp yarns 911 and at right angles to the fabric 913. One end formed by the weft yarn 912 is referred to as a cut 914. The fabric of the woven fabric 91 is relatively compact, but its elasticity is weak and it is easy to be shaped. Further, the knitted fabric 92 is formed by knitting the yarn 921 into a coil 920 by using a knitting needle, and then winding the coil 920 one after another one after another (see Fig. 2). Therefore, the cloth structure of the knitted fabric 92 is loose and rich. elasticity.

The fabric 9 may be further coated on the surface to form a coating, and the coating may be formed into a waterproof, breathable or breathable functional film by a dry coagulation method or a wet coagulation method. In the above process, since the structure of the woven fabric 91 is relatively tight and not easily deformed, referring to FIG. 3, the woven fabric can be directly driven by the roller 61 through a roller coater 6 for coating. The material 5 is directly coated on the surface of the woven fabric 91 to rapidly form a coating 51 of uniform thickness thereon. However, the structure of the knitted fabric 92 is loose and elastic, and if it is moved by the above-described rolling method to perform the coating operation of the paint 5, the knitted fabric 92 is pulled by the roller 61 and stretched and deformed in the warp or weft direction. Once the coating of the coating 5 is completed and is no longer pulled by the roller 61, the knitted fabric 92 is immediately shrunk, so that the coating 51 having a uniform coating thickness is wrinkled and deformed as the knitted fabric 92 is squeezed, thereby causing The coating 51 is uneven in thickness. In addition to this, the knitted fabric 92 is also deformed by being pressed by the weight of the coating material applied thereto, thereby causing uneven thickness of the coating layer 51 coated thereon. However, if the manual blade coating method is adopted, the knitted fabric 92 is still subjected to the tensile deformation of the blade, and eventually the coating 51 is uneven in thickness.

Therefore, in order to solve the problem that the thickness of the coating layer 51 applied directly to the knitted fabric 92 is not uniform, the industry has formed a coating layer 51 having a uniform thickness on the knitted fabric 92 in a separate film forming manner, referring to FIG. The paper 7 is coated to form a uniform coating layer 51 and the coating 51 is cured into a functional film 52 by dry coagulation, and then the adhesive 8 is applied to the surface of the knitted fabric 92 and dried at a suitable temperature. The semi-dry adhesive layer 81 is then joined to the functional film 52 which is cured and formed on the release paper 7, and finally the release paper 7 is peeled off the functional film 52, that is, the functional film having a uniform thickness is formed on the knitted fabric 92. 52.

Although the above method can finally form a uniform thickness functional film 52 on the surface of the knitted fabric 92, the adhesive layer 81 between the functional layer 52 and the knitted fabric 92 somewhat affects the effect of the functional film 52 on the knitted fabric 92. Such as waterproof and breathable or breathable effect. In addition, due to the knot of the release paper 7 Low structural strength, not only easy to break under high tension and tension, such as coating by coating through the above-mentioned roller coater, and the structure is loose after water absorption, and it is easy to disintegrate under external force pulling, so it is not suitable for wet The process of the solidification method.

Therefore, the object of the present invention is to provide a functional knitted fabric processing method which is first combined with the release and replacement of the release carrier, thereby achieving uniform thickness of the functional film formed on the surface of the knitted fabric, and simplifying the process for simplifying the automation. Equipment required for the production line.

Thus, the present invention first combines a functional knitted fabric processing method for coating and replacing a release carrier, comprising the steps of: (A) providing a release carrier having a release surface, and applying a coating to the release carrier. Forming a coating on the off-face; (B) placing a knitted fabric on the coating such that the coating is located between the knitted fabric and the release carrier and attached to the surface of the knitted fabric; Laying the knitted fabric, the coating and the release carrier together in a water tank to wet-solidify the coating, wherein water penetrates the knitted fabric and the coating Dissolving the solvent to solidify the coating into a waterproof, breathable or breathable functional film; and (D) joining the knitted fabric, the functional film and the release carrier after the step (C) The drying treatment is carried out to form a functional knitted fabric by the dried knitted fabric and the functional film attached to the surface of the knitted fabric.

Wherein the tensile strength of the release carrier is greater than that of the knitted fabric The tensile strength, the adhesion of the functional film to the knitted fabric is greater than the adhesion to the release surface.

The invention has the effect of forming a uniform thickness coating by coating the release carrier, and then placing the knitted fabric on the coating so that the coating adheres to the surface of the knitted fabric, and finally The coating is wet-solidified into a film, whereby not only the effect of uniform thickness of the functional film formed on the surface of the knitted fabric but also the conventional method of separately forming a film is eliminated, and the present invention eliminates the need to The work required to glue the functional film to the knitted fabric is more effective in simplifying the equipment required for the automated production line.
