Problems solved by technology

[0005] The present invention aims to overcome the problems of low color fastness to washing of photochromic printing in the above-mentioned prior art, and the photochromic printing is limited by the transparency of the coating so that the discoloration effect is reduced, and provides a photochromic printing coating The preparation process of fabrics, so that the fabrics not only have functions such as waterproof, waterproof and moisture-permeable, and anti-ultraviolet, but also have novel photochromic effects

preparation example Construction

[0014] The preparation process of the photochromic printed coated fabric of the present embodiment comprises the following steps:

[0015] 1. Base fabric: select fabrics suitable for making umbrella covers and curtains, such as polyester fabrics or nylon fabrics of various specifications, which are used after conventional pretreatment or dyed with light colors; polyester yarns with a density of 170T are used in this embodiment Take the fabric as an example, firstly carry out pre-washing treatment and pre-setting processing;

[0016] 2. Preparation of photochromic printing paste and pigment printing paste:

[0017] 1) Photochromic printing paste:

[0018] Components in parts by weight: 5-25 parts of photochromic agent, 60-90 parts of synthetic thickener, 4-15 parts of binder, and the synthetic thickener is converted into 2-3% by weight of synthetic thickener with water. After the thickener is hydrated into a paste, mix it evenly with other components according to the above ra...

Abstract

A Preparation technology of photochromic printing coating fabrics. It includes conventional processing of fabric and preparing coating printing paste, its characteristics is: preparing photochromic printing paste, the paste contains the weight of photochromic agent 5 - 25 , synthesized thickener60 - 90 and adhesives 4- 15; then total photochromic printings or part photochromic printings are added coating printings partly and are dried; then preparing the coating glue which contains solvent-based PU glue or PA glue 80 - 90, nano-UV Shielding agent 0. 5-2, bridge agent for coating 0. 5-1. 5, and organic solvent 5-30, and drying after coating; then sending it to shaping machine with pad-box and water repellent finishing the slop padding fabric, the used water repellent finishing agent is a the water repellent agent with the concentration of 10-60 g / L and the glacial acetic acid using the pH value to 4 - 6; then the photochromic printing coating fabrics are prepared after drying and curing which has photochromic function and waterproof and UV-resistant features.

Description

technical field [0001] The invention relates to a preparation process of a coated fabric, in particular to a process for preparing a photochromic printed coated fabric integrating photochromic function, waterproof, anti-ultraviolet and other functions. Background technique [0002] Coated fabric is one of the most rapidly developing new textile products in recent years. It has been applied in clothing, umbrellas, tents and other daily textiles and industrial fabrics. Coated fabric is a product obtained by coating and finishing ordinary fabrics; the so-called coating finishing is to uniformly coat one or more layers of high polymer on the surface of the fabric to make the fabric have a certain Some functions such as waterproof, waterproof and moisture-permeable, anti-ultraviolet, flame-retardant, anti-static, etc., can even change the appearance and style of the fabric and increase the added value of the product. [0003] In recent years, a class of photochromic materials ha...
