Description

Manufacturing method and structure of imitation paper double wrinkle printing cloth

The present invention relates to a method for making paper-like double-crepe printing cloth and its structure, in particular to a method and structure for making paper-like double-crepe printing cloth with three-dimensional wrinkles and hand touch. The paper-like double-crepe printing cloth has 3D three-dimensional Wrinkle effect, and the surface of the printing layer is covered with a first PU coating, which can prevent scratches from damaging the printed totem. The bottom surface of the imitation paper double wrinkle printing cloth is covered with a second PU coating, which can be waterproof and increase The touch feel, through the present invention, the use characteristics of the fabric can be exerted, and its commercial value can be improved.

The first figure shows a conventional printing cloth 1, which mainly takes a woven cloth 10 as the main body. The surface of the woven cloth 10 is first refined during manufacture to remove the surface of the woven cloth 10 After the remaining oily impurities, the printing totem is then printed on the surface of the woven fabric 10 to form a printing layer 11. At the same time, in order to increase the hardness of the printing cloth 1, a PU coating is applied to the bottom of the printing cloth 1 12. The cloth surface of such printed cloth 1 is only a flat surface, without 3D effect, and the surface of the printed layer 11 is not good at dry and wet friction. Since the printed layer 11 has no protection, it is easily scratched by external forces. The destruction of the printed totem directly affects the service life and appearance of the finished product, so that the usable range of the printed cloth 1 is restricted and its commercial value is affected.

In view of the deficiencies of the traditional printing cloth, the inventor of this case has finally completed the method and structure of the imitation paper double-wrinkle printing cloth of the invention after numerous studies and improvements, which is the purpose of the invention. There are two: The first purpose of the invention is to provide a paper-like double-crepe printing cloth with three-dimensional wrinkles and hand touch. The paper-like double-crepe printing cloth made by the method of the present invention has a 3D three-dimensional crepe effect. And the front surface of the printed layer is covered with a first PU coating to prevent scratches from damaging its printed totem, and the underside of the imitation paper double-wrinkle printed fabric is covered with a second PU coating, which can be waterproof and increase the touch feel Through the present invention, the use characteristics of fabrics can be exerted, and the commercial value can be improved.

The second purpose of the present invention is to provide a paper-like double-wrinkle printed fabric structure with three-dimensional wrinkles and hand touch. In addition to the 3D three-dimensional wrinkle effect, it can also prevent the printed layer from being scratched and damaged, and increase the touch and feel, which is effective Those who make use of the characteristics of fabrics and enhance their commercial value.

In order to achieve the above-mentioned purpose of the present invention, the method of making a paper-like double-wrinkle printing cloth of the present invention includes the following steps: a. Surface refining treatment, refining and purifying the surface of a woven cloth to remove the residue on the surface of the woven cloth Oily impurities; b. Wrinkle treatment, after the high-pressure pre-treatment is completed, and then the pressure is rapidly exhausted, so that the woven fabric shows a plurality of irregular wrinkle-like concave and convex marks as a whole, and becomes a pair of wrinkles; c. Printing , Print the printed totem on the front side of the double crepe cloth by digital direct jet printing, and form a printing layer attached to the front side of the double crepe cloth; d. The first PU coating treatment, on the surface of the printed layer Cover a first PU coating; e. Second PU coating treatment, cover a second PU coating on the bottom of the double wrinkle cloth.

In the above step c, the color material used in the digital direct-injection printing method is water Solvent pigments.

The paper-like double wrinkle printed fabric structure of the present invention includes a double wrinkle fabric, a printing layer, a first PU coating and a second PU coating, wherein: the double wrinkle fabric includes a front surface and a bottom surface, the The front surface and the bottom surface are not on the same plane, and the front surface and the bottom surface are provided with a plurality of irregular wrinkle-like concavo-convex marks; the printing layer is printed on the front surface of the double-crepe cloth by digital direct-jet printing. ; The first PU coating, covering the surface of the printing layer; the second PU coating, covering the bottom surface of the double wrinkle cloth.
