The environment-friendly resin is a series of products processed from vegetable oil with high softening point, high viscosity, and better oxidation resistance, and is completely resistant to crystallization in liquid state or in solution. Its multiple uses include paint, drying agent, synthetic resin, automobile ink, floor tile, rubber compound, solder paste, and various adhesives and protective coatings.

In daily life, many people choose to use softeners to increase the softness of their clothing, making it more comfortable to wear and having a certain maintenance effect. Although softeners are a common household product, the composition and principle of softeners are unknown to many people. This article will analyze the composition of softeners and explain their principles of softening clothing

1. Environmental protection, no pollution to the environment2. After being fixed with a fixing agent, it should be able to comprehensively improve various dyeing fastness, including soap washing, dry rubbing, wet rubbing, and sweat stain fastness

Fixing agents are additives used to improve the dyeing fastness of dyes on fabrics. As a finishing agent, it can combine with the ionic water-soluble groups of dyes to form insoluble colored substances, improving the washing and sweating fastness of colors, reducing the hydrophilicity of dyes, effectively improving the fixation rate, water washing resistance, friction fastness, and dye utilization rate of dyes, and sometimes improving their light fastness.

The pulp fibers are always yellow to grayish white, which is due to the absorption of purple and blue light with wavelengths of 0.4-0.5 um by the lignin contained in the pulp fibers. The higher the lignin content in the pulp, the darker the color. Grinded wood pulp contains a large amount of lignin, which is light yellow in color. Fluorescent whitening agents can be added to improve whiteness. Today, the editor will take you to understand the whitening principle of fluorescent whitening agents and the factors that affect their whitening effect.

Dyes are not unfamiliar to us, and they are indispensable in daily life. Simply put, dyes can be divided into two types: chemical dyes and environmentally friendly dyes. Chemical dyes are dyes made from compounds through a series of chemical reactions or directly using colored chemical substances. Environmental friendly dyes are different, as they are obtained from plants, animals, or mineral resources and have hardly undergone chemical processing.
