As a socks industry supplier, we encounter many customers have the need to print logo or other patterns, so today we talk about some printing processes.

1. Glue Printing Process

The glue printing process uses special chemical gels to blend highly seamlessly with dyes. Dye through gel medium, firmly adhere to the fabric, glue printing process overcomes the limitations of water paste printing. It can be printed on blended fabrics of cotton, linen, viscose, polyester, nylon, polypropylene, chloroprene and various fibers, as well as on leather, artificial leather and other materials.Ink-jet printing, rotten flower printing, electrostatic flocking printing and other printing process. The biggest advantage of glue printing process is widely used, beautiful color, high degree of reduction, but its printing process is more complex than water pulp printing process, the cost is relatively high.

The appearance and wide application of glue paste after water paste because of its coverage is very good, so that dark clothes can also be printed on any light color, and a certain degree of gloss and cube sense to make the clothing look more high-end, so it has been rapidly popularized, almost every graphic T-shirt will use it. But because it has a certain degree of hardness, so it is not suitable for large area of field pattern, large area of pattern is best to print with water slurry, and then dotted with some glue, so as to solve the problem of large area of hard glue slurry, but also can highlight the sense of hierarchy of the pattern; There is also a method is to steal a large area of field design, make it rotten effect, but always wear a little hard, so it is better to combine water and glue to solve the problem of large area printing.

2. Water Slurry Printing Process

Water slurry printing process is one of the most basic printing process in the screen printing industry, which can be used in cotton, polyester, hemp and so on, almost all the light background fabric printing, is very widely used. It works in a similar way to dyeing, except that it “dyes” an area of the fabric into the desired color of the flower position. Therefore, the biggest advantage of this process in the dark background fabric can not be applied to the waterpulp printing process is that it is widely used, the color fastness is very good, and can be used to print a better effect at a relatively low price. The limitation of the waterpulp printing process is that it can not be applied to all dark fabrics.

3. Thermochromic Printing

The early thermochromic printing has used thermochromic dye processing into microcapsules, printed on the fabric, it has reversible and irreversible two categories. Irreversible thermochromic dyes are commonly used as temperature indicators. It is generally reversible for use on textiles. According to its structure can be divided into inorganic and organic two categories, organic thermochromic dyes are widely used in textiles, it is composed of cryptochromatic dyes, chromogenic agents and sensitizers (desensitizers).

Cryptochromatic dyes are some substances that combine protons to produce color, such as lipids and pentagalamine compounds, which serve as electron donors in the color-changing system. Chromogenic agent is a kind of acid-releasing characters that can release protons, such as phenols, carboxylic acids, halogenated alcohols and so on, which are electron-absorbing compounds. The discoloration system of cryptochrome dye and chromogenic agent can achieve the discoloration effect in a special solvent. The molten body of this solvent has good solubility of dye and chromogenic agent, and can enhance the thermal sensitivity of the system, so it is called sensitizer (desensitization agent). Sensitizers are generally fusible fatty alcohols, fatty acids and their esters, aromatics and their ethers and ester compounds, and directly determine the color change temperature.
