The history of fabric waterproof finishing has a long history. It was found that paraffin and wax-like substances can be applied to the surface of the fabric after heating, so that the fabric has a waterproof function.
Development forecast of waterproofing agent market:
my country has become a major textile exporter for the first time since 1994, and has maintained a leading position since then.
With the development of economy and technology, the functionality of textiles is also important. The waterproof function has always been the most important one in the functional textile finishing technology, so the development of the textile waterproofing agent market is also increasing.
The development history of textile waterproofing agent:
At the beginning of the 19th century, the waterproof finishing of aluminum soap and paraffin emulsion appeared. This waterproofing agent has good water repellency, but the disadvantage is that it is not resistant to washing.
In the 1930s, long carbon chain water repellents appeared. This kind of water repellent can form cellulose ether with cellulose macromolecules, and has good and lasting water repellency.
In the 1940s, DuPont proposed a coordinating complex waterproofing agent, but this type of waterproofing agent itself is green in color, thus limiting its scope of use.
In the late 1940s, silicone water repellants appeared, which are especially suitable for various synthetic fiber and wool fabrics, and can also be used for cellulose fiber fabrics.
In the 1950s, DuPont took the lead in publishing a patent for fluorochemical water repellents. Fluorochemical water repellants were not only waterproof, but also oil-repellent, and did not damage the style of fibers, which made fluorochemical water repellents rapidly popularized and applied. , has become today’s mainstream waterproofing agent.
In the 1960s, the research and application of fluoropolymers was further developed in the United States and Japan, with the introduction of comonomers to reduce prices and improve durability.
After the 1970s, the United States, Japan and other countries began to publish articles and patents on fluorine-free water repellents.
The diluent of Tianshi textile wax emulsion can effectively improve the water repellency of fibers when used for textile waterproofing, and effectively improve the color strength without affecting the reprintability. Add a small amount, 3-4%.
Advantages of wax emulsion for textile:
*Anti-acid, anti-alkali, resistant to hard water, strong water solubility.
*No demulsification, no clumping and long shelf life.
*Emulsion is stable and does not delaminate when diluted with any proportion of water.
*High solid content and good dispersibility.
