Hygroscopicity: Cotton fiber has good hygroscopicity. Under normal conditions, the fiber can absorb water into the surrounding atmosphere. Its moisture content is 8-10%, so it contacts human skin and makes people feel soft without stiff. If the humidity of the cotton cloth increases and the ambient temperature is high, the water content in the fiber will all evaporate and disperse, so that the fabric maintains a water balance state, which makes people feel comfortable.
Warmth and antistatic: Since cotton fiber is a poor conductor of heat and electricity, the heat transfer coefficient is extremely low, and because the cotton fiber itself has porosity and good elasticity, a large amount of air can be accumulated between the fibers, and the air is hot. Poor conductors of electricity and electricity, therefore, cotton fiber textiles have good thermal insulation and antistatic properties, and the use of pure cotton fabric makes people feel warm and comfortable.
Heat resistance: The cotton fabric has good heat resistance. When it is below 110 °C, it will only cause water evaporation on the fabric and will not damage the fiber. Therefore, at room temperature, wearing, using, washing and dyeing have no effect on the fabric. This improves the washability and heat resistance of the cotton fabric.
Alkali resistance: cotton fiber has strong resistance to alkali. In alkaline solution, cotton fiber does not break. This property is beneficial to the washing, disinfection and disinfection after use, and is also beneficial to pure cotton textiles. Dyeing, printing and various processing to produce more new varieties of cotton.
Hygiene: Cotton fiber is a natural fiber, its main component is cellulose, and a small amount of waxy substances, nitrogenous substances and pectin. After many aspects of inspection and practice, pure cotton fabric has no irritating and negative effects on the skin. It is beneficial to the human body for a long time and has good hygienic performance.
Mono Calcium Phosphate ,the chemical formula is Ca (H2PO4)2.H2O, molecular weight of the body is 252.06, after dryed the product is white or slightly yellow micro powder or granules, the relative density of 2.22 (16 °C). Slightly hygroscopic, soluble in hydrochloric acid, nitric acid, slightly soluble in cold water, almost insoluble in ethanol. At 30 °C, 100 ml of water soluble MCP 1.8g. The aqueous solution was acidic, heating the aqueous solution can get calcium hydrogen phosphate. Lose crystal water at 109 °C and decomposed into calcium metaphosphate at 203°C. Applications:Monocalcium Phosphate is used to supply mineral nutrition such as phosphorus (P) and calcium (Ca) for animal, which can be easily digested and absorbed. Extensively applied as additives of Phosphorous and Calcium in aquatic animals feed.Higher water solubility of MCP is required in aquatic animals feed.
