At present, the synergistic technology of Textile Auxiliaries can be divided into two ways
The first way is to use two or more different additives with a certain performance in accordance with a certain principle of preparation, known as the external compound way, made of new varieties with excellent performance than the composition, which is at home and abroad, especially domestic development New Textile Auxiliaries are mainly used in the way.
For example, amino silicone softener has excellent durability, but poor water absorption, through the complex polyurethane prepolymer, can be made both silicone-specific flexibility, smoothness, but also polyurethane prepolymer With a sense of fullness \ soft rebound and water absorption of new varieties;
(AEC) is excellent in biodegradability, hard water, excellent emulsification, dispersion, wetting, solubilization and other properties, is the main raw material for the manufacture of green pretreatment agent, it is with the alkyl Silicone compound not only retains the above advantages, but also improve the soft effect, so that the fabric is not wrinkle yellow, is an excellent green fabric softener.
The second way is to introduce the functional group of the other adjuvant on the structure of the adjuvant, so that the new adjuvant has a new function, called the internal compound, such as the introduction of an emulsifiable group on the organosilicon molecular chain , So that the new additives can be emulsified without emulsifier into microemulsion.
According to its different chemical structure characteristics, Textile Auxiliaries are mainly divided into surfactants and polymers and two categories. Depending on their ionic properties, surfactants can be divided into anionic, cationic, amphoteric and nonionic.
Depending on their hydrophilic groups, the anionic surfactants can be classified into aliphatic carboxylic acid salts, fatty alcohol sulfuric acid ester salts, alkyl sulfonates, alkyl benzene sulfonates and phosphoric acid ester salts. As the longest application, the largest and lowest price of surfactants,Textile Auxiliaries anionic surfactants have excellent net cleaning, emulsification and solubilization, in the textile processing process is mainly used as a net lotion, wetting Agents, scouring agents and leveling agents.
According to their different structure, cationic surfactants can be divided into primary amine salt, secondary amine salt, tertiary amine salt and quaternary ammonium salt. Because of its strong emulsification,Textile Auxiliaries dispersion and foaming effect, cationic surfactants in the textile processing process commonly used as softeners, antistatic agents and leveling agents.
According to its different structure, amphoteric surfactants can be divided into amino carboxylic acid, betaine and imidazoline type. It not only has a good penetration,Textile Auxiliaries emulsification and net cleaning and other effects, and its biodegradability is low, compatibility is good, often used in textile finishing softener, leveling agent.
According to its different structure, non-ionic surfactants can be divided into fatty alcohol polyoxyethylene ether and alkyl phenol polyoxyethylene ether two categories. Because of its strong emulsification, degreasing, solubilization and low foam and other properties, so its textile processing in the larger amount, second only to cationic surfactants, commonly used as emulsifier, leveling agent and scouring agent
