Description

Multiple embossed cloth and manufacturing method thereof

The invention relates to the technical field of embossed cloth, in particular to an embossed cloth which simultaneously presents a bright pattern and a three-dimensional embossing effect.

Applicants have shown that the use of hot-rolling calendering or embossing methods for treating general fabrics may cause gloss or unevenness in the surface of the fabric, but it does not simultaneously exhibit two effects. Moreover, the conventional embossing technique for producing a bright pattern uses a flat embossing wheel to emboss the cloth at a high temperature to form a bright pattern on the surface of the cloth, but if a flat embossing wheel is used, the embossed pattern cannot be exhibited. Therefore, the area of the embossed cloth having the embossed embossed pattern is the same as the area having no embossed embossing pattern, and thus is still monotonous in appearance and touch.

It is an object of the present invention to provide an embossed fabric which simultaneously exhibits a bright pattern and a three-dimensional embossing effect.

The present invention provides an embossed cloth having at least one bright pattern area and at least one three-dimensional embossed area.

The invention also provides a method for manufacturing an embossed fabric, comprising the steps of: (a) providing a fabric and providing an embossing wheel, wherein the embossing wheel has at least one convex plane and at least one deep groove. (b) subjecting the embossing wheel to the appropriate temperature and pressure conditions The fabric is embossed so that the fabric forms a concave embossed area corresponding to the deep groove of the embossing wheel, and a bright pattern area is formed on a portion corresponding to the convex plane of the embossing wheel. Obtain the embossed cloth.

The invention further provides a method for manufacturing an embossed cloth, comprising the steps of: (a) providing a cloth and providing two or more embossing wheels, wherein at least one embossing wheel has at least one deep groove, at least one The embossing wheel has at least one convex plane, and (b) at least one embossing wheel having at least one deep groove or at least one embossing wheel having at least one convex plane or under appropriate temperature and pressure conditions Alternatingly, the embossing is performed on the fabric so that the fabric forms a concave and convex embossed area on a portion of the deep embossing groove corresponding to the embossing wheel having at least one deep groove, and correspondingly has A portion of the convex plane of the at least one convex embossing wheel forms a bright pattern area to obtain the embossed cloth.

The embossed cloth provided by the invention can simultaneously exhibit the bright pattern and the effect of three-dimensional embossing on the surface, thereby increasing the diversification and applicability of the embossed cloth pattern and the touch.
