Problems solved by technology

However, there are the following problems in these plate-making printing methods: the number of colors is limited; although the multi-color feeling can be reflected in the printing of the three-primary-color decomposed pattern frame, it is difficult to adjust the hue and density of the three-primary-color composition; due to the formation of multiple Layers are prone to lack of reproducibility of printing processing, etc.
In addition, in small batch production, the following problems have been pointed out: the cost of engraving (plate making) becomes expensive, and in printing processing, it is necessary to prepare more color paste than the amount required for processing, which leads to waste and loss of materials.
For example, due to the low melting point of the release agent, the drying temperature after application of the mixed paste is limited, making it difficult to increase production speed

Embodiment 1

[0096] As the ink receiving layer and the adhesive layer, 134 g of Poval AP-17 (15% aqueous solution of water-soluble polyvinyl alcohol-based adhesive: Japan Vam & Poval Co., Ltd.), HYDRAN AP-20 (water-based polyester / Polyurethane-based adhesive 45% solution: manufactured by DIC Corporation) 100g, urea 20g, dicyandiamide 10g, soda ash 30g, FD algin BL (manufactured by Furukawa Chemical Industry Co., Ltd.: sodium alginate low-viscosity powder) 10g, 86 g of water, 10 g of thickener F (acrylic synthetic paste: manufactured by Sano Co., Ltd.), and a total of 400 g of the mixture were fully stirred with a high-speed dispersion mixer (about 5000 r.p.m.) to prepare a high-viscosity paste. Using a coater (manufactured by Yokoyama Seisakusho Co., Ltd.), the mixed paste that will become the ink receiving layer and adhesive layer is applied to paper (manufactured by Nippon Paper Co., Ltd., unbleached kraft paper, 70 g / m 2 , thickness 0.15mm) and dry. The coating amount (dry weight) of ...

Embodiment 2

[0100] Use FD algin BL 65g instead of FD algin BL 10g in Example 1, subtract the thickener F, increase the amount of water used to 300g to adjust the viscosity, and change the adhesion temperature of the printing and dyeing paper to 140°C. Other than that, the same treatment was carried out. As a result, in the same manner as in Example 1, a finely patterned, fast, and densely dyed printed fabric showing a soft hand was obtained.

Embodiment 3

[0102] As the ink receiving layer and adhesive layer, 85 g of NK BINDER M-302HN (46% aqueous solution of water-soluble acrylic adhesive: manufactured by Shin-Nakamura Chemical Industry Co., Ltd.), Poval AP-17 (water-soluble polyvinyl alcohol adhesive) Mixture 15% aqueous solution: Japan Vam & Poval Co., Ltd.) 134g, urea 30g, dicyandiamide 10g, soda ash 35g, FD algin BL (Furukawa Chemical Industry Co., Ltd.: sodium alginate) 10g, water 96g The mixture is fully stirred with a 5000r.p.m. high-speed dispersing mixer to make a high-viscosity paste. The mixed paste for the ink receiving layer and adhesive layer was applied to inorganic coated paper (manufactured by Mishima Paper Co., Ltd., 50 g / m) using a coater. 2 ) and dry. The coating amount (dry weight) of the mixed paste is 40g / m 2 . In this way, printing and dyeing paper for reactive dyes is obtained.

[0103] Next, the reactive dye ink (C.I. Reactive Yellow 9515%, polyethylene glycol 5%, glycerin 5%, ε-caprolactam 5%, ion...

Abstract

Disclosed is a paper printing method for fibrous and leather materials characterized by having: a step wherein printing paper is obtained by applying a mixed paste comprising a water-soluble synthetic binder, a natural adhesive, and an auxiliary agent to base paper, which is then dried to obtain paper for printing, onto which a dye ink is printed; a step wherein the printing paper is bonded to a fibrous or leather material and fixed using pressure / heat; and a step wherein the printing paper is removed after a dye fixing process is carried out while the printing paper is fixed to the fibrous or leather material. Further disclosed are the paper for printing and the printing paper used in the paper printing process, and the fibrous and leather materials characterized by being printed on in the paper printing process.

Description

technical field [0001] The present invention relates to a printing method of fiber material or leather material using printed paper. More specifically, the present invention relates to a printing and dyeing method for fiber materials or leather materials, which is characterized in that a mixed paste composed of a water-soluble synthetic adhesive, a natural paste, and an auxiliary agent is applied to a base paper to form a dyeing method. Dye ink is printed on the printing paper, and dye fixing treatment (steaming, etc.) [0002] In addition, this printing and dyeing method is a new type of processing method, which is characterized in that steaming treatment is performed in a state where printed paper is adhered to a fiber material or a leather material, and it is named "paper printing and dyeing method". In addition, the "base paper for printing and dyeing" used in this specification and claims refers to base paper for printing and dyeing paper, "paper for printing and dyeing"...
