According to the type of resin, there are thermosetting and thermoplastic resins, but thermosetting resins are the main type. For example, urea formaldehyde resin, melamine formaldehyde resin, thiourea resin, epoxy resin, etc., are actually the initial contractions of resin monomers. These initial contractions can be dissolved in water or solvent, penetrate into the interior of the fiber, and then undergo high-temperature baking. The active group undergoes covalent crosslinking reaction with the hydroxyl group in the long chain molecules of cellulose, connecting the adjacent molecular chains of cellulose fibers or forming a network structure of polymers in the gaps of the fibers and depositing, Thus, the fabric maintains a long-lasting wrinkling effect.

The purpose of washing water: 1. Enhance the stability of clothing. By washing water, it can shrink in advance and stabilize the size. 2. The aesthetics of clothing are enhanced, and different washing methods can produce various colors and textures with different effects, which are highly favored by people and increase the added value of clothing. What is the difference between rinsing cloth and washing cloth? Washing cloth requires a washing process before leaving the factory. The purpose is to shrink the cloth, or add some additives to make the fabric soft, make the color soft, and so on. The fabrics used in some casual clothing series and Niuzi series are all washed fabrics.

荧光增白剂的品种甚多，各种纤维的增白都用有一定牌号的增白剂。虽然各种增白剂的化学结构和性能不同，但对纤维或织物的增白原理都是一样的。其增白原理主要是由于增白剂的分子中含有共轭双键系统，具有良好的平面性，这种特殊的分子结构在日光照射下能吸收日光中紫外线（波长为300～400nm）而发出蓝紫色光（波长为420～500nm），蓝紫色光与纤维或织物上的黄光混合而变成白光，从而使纤维或织物明显变白。

广东天盛新材将顶染工艺与常规工艺进行了对比，并在染料配制上进行了改进，以找出最适合皮革黑的染色工艺。可知，采用顶染工艺，乌黑度、耐干湿擦都比常规工艺好，吸收性、丝光感也好一些，如果在二次染色时加少量的皮革棕，则成革的丝光感和粒面就更好一些了。

外界因素如溶剂、温度、染料浓度、染液中加入的电解质、照射光线等都会使染料在溶液中，或在染色织物上的状态发生变化，导致染料的颜色改变。
