Problems solved by technology

However, the problem with the above method is that the processed substrate can only be nylon fabric with strong water resistance, and the water-repellent area is relatively large, which will seriously affect the air permeability and comfort of the fabric when used in clothing fabrics.
[0005] Chinese patent application 02117254.4 "A batching and preparation process of wet-developed calico" discloses a printing potion prepared with special chemical water, special waterproofing agent, emulsifier and water, but does not specify the special chemical water and special chemical water used. What are waterproofing agents
However, the pattern layer in this patent application uses polyoxyethylene ether emulsifier and sulfonic acid group and alkyl polyglycol ether mixture penetrating agent as essential components, and the use of penetrating agent is not conducive to forming a clear pattern
In addition, the slurry used contains organic solvents, which are unfriendly to the human body and the environment
[0006] The fabrics made in the above three patent applications have poor hand feel and feel uncomfortable when worn by the human body

Abstract

The invention discloses a product turning liquid into printing and a production method thereof. A water repellent layer with colorless patterns is formed on a hydrophilic substrate, so that different areas of the substrate surface respectively have water repellency and hydrophilicity. When the substrate is wetted, the patterns of the areas of the water repellent layer with the colorless patterns can be clearly shown because of different water content. Therefore, the product turning liquid into printing has multiple uses, for example, the product can reduce visual unhappiness caused by local wetness of fabric surface when a human body sweats, can be used for showing a urine wetting function of paper diapers of children, and can also be used as textiles of face towel, bath towel and the like for the children; and when the face towel or bath towel is wetted, patterns or flowers or figures thereon can be shown vividly, and the curiosity of the children is enhanced.

Description

technical field [0001] The invention relates to a shadow printing technology, in particular to the production process and products of the liquid variable printing technology. Background technique [0002] The basic concept of traditional printing formed in people's minds is that the surface of the printed fabric presents a visible bright graphic pattern, no matter how the environment changes, the printed pattern is always the same, that is, the printed pattern is static . Shadow printing technology refers to the printing of a special material on the substrate by screen printing or inkjet printing, so that the pattern on the substrate changes with the ambient temperature, light and shade, and the dryness and humidity of the fabric. Emerging printing technology. Liquid variable printing technology is a kind of shadow printing technology. [0003] The pattern pattern of liquid variable printing products is invisible to the naked eye under normal environmental conditions. It...
