1. Choosing dyes according to the nature of the fiber. Because of the different nature of various fibers, it is necessary to select suitable dyes when dyeing. For example, when cotton fiber is dyed, because its molecular structure contains many hydrophilic groups, it is easy to absorb moisture and expand, can react with reactive groups, and is more alkali-resistant, so you can choose direct, reduced, vulcanized, and ice dyes. And reactive dyes. Polyester has strong hydrophobicity and is not alkali-resistant at high temperatures. Under normal circumstances, the above dyes should not be used, but disperse dyes should be used for dyeing. The bulk casting material is prepared by the copolymerization of ester and polyfunctional monomers or other polyfunctional vinyl monomers through casting polymerization. Mainly used as aircraft hatch cover and windshield. Solution, semi-emulsion, and water-based thermosetting resins need to be heated and baked to cross-link and solidify to form a film to form a network structure. There are two types of cross-linking: 1 reactive cross-linking type, the functional groups in the polymer have no cross-linking reactivity, and cross-linking components with at least 2 functional groups must be added, such as resin, epoxy resin, urea resin and metal oxide, etc. After the reaction, cross-linking and curing, the cross-linking component can not be stored for a long time after being added, and should be used in time; 2 self-cross-linking type, the polymer chain itself contains more than two reactive functional groups, carboxyl groups, amide groups, etc., Heating to a certain temperature or adding a catalyst at the same time, the functional groups react with each other to complete the cross-linking. This kind of thermosetting resin is mainly used as fabric, leather, paper treatment agent, industrial paint and architectural coating.
