According to the principle of scouring agent, as a high-efficiency scouring agent, it must have the conditions of rapid penetration, strong emulsifying and dispersing ability, high cleaning power, low foaming ability, high temperature resistance, concentrated alkali, hard water, easy biodegradation, Read More
The viscosity of amino silicone oil is directly proportional to the molecular weight. The larger the molecular weight, the better the film-forming properties of amino silicone oil on the fabric and the softer the hand feel. However, because the amino silicone oil molecules are cross-linked when the Read More
Many dyeing masters may sneer and disagree. In actual operation, many dyeing masters used the wrong method of direct pumping to make more output, which caused uneven soft oil on the cloth surface! In production, the touch panel is often used, and the color light is normal, but after the finalization Read More
Oven method1. PrincipleDry a sample of a certain mass at a certain temperature under normal pressure for a certain period of time, and express the solid content as the percentage of the mass of the sample after heating to the mass of the sample before heating.2. Determine step aggregationTake three Read More
It can be quickly diluted and dissolved in a lower temperature water environment to play its good role. Cold water film plays an indispensable role in improving the product quality and added value of textiles. It can not only give textiles various special functions and styles, such as softness, anti Read More
In general, an effective defoamer must satisfy the following conditions:• Must have a higher surface activity than a foaming surfactant, i.e. it must have a lower surface tension.• Easy to disperse in a system• It must be insoluble (at least partially insoluble) in the foaming medium, or it will act Read More
The various properties (such as soft hand feel, smoothness, elasticity, etc.) imparted to the fabric by amino silicone oil are all caused by the amino groups in the polymer. The ammonia value is proportional to the amino content (percentage) in the amino silicone oil. The higher the amino content, t Read More
A class of organic compounds that can improve the whiteness of fiber fabrics and paper. Also known as optical brightener and fluorescent brightener. Fabrics are often yellow because they contain colored impurities. In the past, chemical bleaching methods were used to decolorize. Nowadays, brightener Read More
