Abstract

The invention discloses a multifunctional fabric finishing agent and a preparation method thereof. Using long-chain alkyl primary amines, epoxy double-capped heads, γ-piperazinylpropylmethyldimethoxysilane, octamethylcyclotetrasiloxane, and long-chain alkyl chlorides as raw materials, synthesize organic Silicon-type multifunctional finishing agent; by introducing a long carbon chain alkyl molecular segment at both ends of the piperazine-containing polysiloxane molecular segment and the piperazine group, it reduces the yellowing of the nylon fabric after finishing and gives Its soft, smooth and fluffy feel, at the same time, utilizes the good water repellency of the polymethylsiloxane segment and the long carbon chain alkyl segment, endowing the nylon fabric with good water repellency. According to the principle of structural similarity, under high-temperature baking conditions, the amide-based molecular segment contained in the molecular structure of the silicone-type multifunctional finishing agent forms a co-crystal with the molecular segment of the polyamide fiber to endow the nylon fabric with various functions. It is washable and water-repellent, and does not contain fluorine and formaldehyde, meeting 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...
