Problems solved by technology

However, due to the lack of reactive groups with fibers in traditional organosilicon compounds and long carbon chain aliphatic hydrocarbon compounds, crosslinking agents need to be added to improve the bonding fastness of finishing agents and fibers when finishing fabrics, which will cause fabric Decreased feel, air permeability and moisture permeability

Abstract

The invention discloses a multifunctional textile finishing agent and a preparing method thereof. According to the preparing method, long-carbon-chain alkyl primary amine, an epoxy bi-end-blocking agent, gamma-piperazine propyl methyl dimethoxy silane, octamethyl cyclotetrasiloxane and long-carbon-chain alkyl acyl chloride are adopted as raw materials to synthesize the organic silicon multifunctional finishing agent; long-carbon-chain alkyl molecular chain segments are introduced into the two ends of polysiloxane molecule chain segments containing piperazinyl groups and the piperazinyl groups,so that yellowing of a nylon textile after finishing is reduced, and the nylon textile is endowed with soft, smooth and fluffy handfeel; meanwhile, by using good water resistance of the polymethylsiloxane chain segments and the long-carbon-chain alkyl chain segments, the nylon textile is endowed with good water resistance. Depending on a structural similarity effect principle, under a high-temperature baking condition, by using the amide group molecule chain segments which are contained in the organic silicon multifunctional finishing agent molecular structure to form eutectic with molecularchain segments of polyamide fibers, the nylon textile is endowed with multiple functions of washing resistance and water resistance, does not contain fluorine and formaldehyde and accords with environmental protection requirements.

Description

technical field [0001] The invention relates to the technical field of synthesis of textile printing and dyeing auxiliaries, in particular to a soft, smooth, fluffy and water-repellent finishing agent suitable for nylon fabrics and a preparation method thereof. Background technique [0002] With the development of society and the improvement of living standards, people have higher and higher requirements for the beauty, fashion and high-end of textiles. At the same time, they also have high requirements for the comfort and functionality of textiles. However, at this stage, the market Whether it is water-repellent or soft, most of the textile functional finishing agents are single-functional products. The research and development of multifunctional finishing agents will become an important development direction of the textile printing and dyeing auxiliaries industry. [0003] As a branch of amino silicone oil, piperazine amino silicone oil not only contains the excellent soft...
