Abstract
The invention relates to the field of textile auxiliary agents and in particular relates to a preparation method of a natural alcohol ether modified organic silicon hydrophilic softening agent. The natural alcohol ether modified organic silicon hydrophilic softening agent is prepared from the following components in parts by weight: 100 parts of side-chain hydrogen-containing polydimethylsiloxane,45 to 60 parts of xylitol monoallyl ether and 4 to 6 parts of allyl glycidyl ether into a reaction container with a condensation and refluxing device; introducing nitrogen gas for 0.5h; then startingto stir; adding 0.003 to 0.005 part of a chloroplatinic acid catalyst; then heating to 85 to 100 DEG C and carrying out heat insulation for 2 to 3h to obtain the natural alcohol ether modified organic silicon hydrophilic softening agent. The softening agent can be subjected to crosslinking reaction in a finishing process and the washing resistance of finished textiles is improved.
Description
technical field [0001] The invention relates to the field of textile auxiliaries, in particular to a preparation method of a natural alcohol ether modified silicone hydrophilic softener. Background technique [0002] The traditional polyether silicone hydrophilic softener is obtained by the addition reaction of allyl polyoxyethylene polyoxypropylene ether and side chain hydrogen-containing polysiloxane. Its hydrophilic property is excellent, but the softness of the fabric after finishing Poor, the hydrophilic performance drops greatly after washing. Moreover, allyl polyoxyethylene polyoxypropylene ether will generate by-products such as propylene ethers, aldehyde compounds, peroxides, etc. during the production process. The residue of these by-products will bring some special smells to the product and have certain irritation to the skin. Therefore, traditional polyether-type silicone hydrophilic softeners are difficult to meet the requirements of some high-required hydroph...
