Abstract

The invention relates to the technical field of organic silicon softeners, in particular to an environment-friendly odorless hydrophilic organic silicon softener for wool tops and a preparation method thereof.The environment-friendly odorless hydrophilic organic silicon softener is prepared from, by mass, 100-200 kg of hydrogen-terminated silicone oil, 200-400 kg of allyl epoxy polyether, 0.1-1 kg of a catalyst, 60-90 kg of an amino silane coupling agent, 350-450 kg of an environment-friendly solvent, 5-20 kg of glacial acetic acid and the balance water. Due to the self-dispersion characteristic of amino polyether polysiloxane, the silicone oil can be self-emulsified in water, but due to intermolecular winding and the super-strong water absorption and thickening effect of polyether, if no solvent is involved, the emulsification can become very difficult. The silicone oil needs to be dispersed and diluted by a proper environment-friendly, odorless and non-toxic solvent to improve emulsification, so that a microemulsion which is suitable for use and has proper viscosity is prepared.

Description

technical field [0001] The invention relates to the technical field of organosilicon softeners, in particular to an environmentally friendly, odorless and hydrophilic organosilicon softener for wool tops and a preparation method. Background technique [0002] Mercerized wool is generally softened with hydrophilic silicone oil, shrink-resistant wool is softened with aliphatic cationic film fluid + hydrophilic silicone oil, and Basolan wool is softened with aliphatic cationic film fluid. After the soft sheet is spread into a film on the surface of the fiber, due to the unevenness of the fiber surface, it will fall off to varying degrees after being subjected to external forces in the subsequent carding and spinning process, thus forming "fly ash" and "dust", and even in the subsequent dyeing process Due to its uneven or unclean shedding after high-temperature melting, it causes dyeing defects. If the hydrophilic silicone oil contains a solvent with a taste and pungent odor, f...
