Embodiment 1

[0043] An organosilicon composite multifunctional textile finishing agent, the structural formula is as follows:

[0044]

[0045] In the formula: n=150; a=14; b=18; R1 is: R2 is: -CH 3 , R3 is: -CH 2 OH,

[0046] The steps for preparing the present invention are:

[0047] A. Put the allyl polyether (compound of formula II) with a=14 and b=18 into a four-necked flask, then add tin tetrachloride protective agent at 10°C, stir well, and then add the compound epichlorohydrin dropwise , Which is the compound of formula III, then heated to 90°C and reacted for 3 hours, cooled to below 40°C, centrifuged and filtered, and then purified to obtain a light yellow oily liquid compound, namely the compound of formula IV;

[0048] B. Add the light yellow oily liquid compound (compound of formula IV) prepared in step A, hydrogen-terminated polysiloxane (compound of formula V) with a degree of polymerization of 150 and isopropanol solvent into a four-necked flask, and raise the temperature to 80°C ...

Abstract

The present invention relates to technical field of textile finishing agent, especially relates to an organic silicon composite multifunctional textile finishing agent with the above structural formula. In the formula: n, a and b are positive integers, n is between 20-200, a is between 5-50, b is between 5-50; R1 is as above, or R2 is: -(CH2)q-CH3, R3 is: -(CH2)m-R, wherein R is hydrogen or hydroxyl radical, q is an integer between 0-6, m is an integer between 1-6. The organic silicon composite multifunctional textile finishing agent provided by the present invention has effects of lasting disinfection, moisture absorption and sweat discharge, has good smoothness, softness and color stability; the present invention has inhibitory rate of 95% or above to bacillus coli and improves soaping fastness and rubbing fastness to level 3 or 4.

Description

Technical field: [0001] The invention relates to the technical field of textile finishing agents, in particular to an organosilicon composite multifunctional textile finishing agent. Background technique: [0002] Silicone is a new high-tech material with broad chemical and physical properties. It has become the material of choice for various industries from aerospace to textile to improve product performance and product quality. By grafting the corresponding functional groups on the siloxane molecular chain segment, it can have good hydrophilicity, hydrophobicity, antistatic properties, softness, smoothness, antibacterial and other functions, and it is non-toxic and non-toxic. Stimulus, so it is considered to be the representative of the future textile printing and dyeing auxiliary. However, the current international and domestic silicone products have a single function. For example, a cross-linked polysiloxane fiber finishing agent disclosed in Chinese patent CN101003947A can ...
