Abstract

The invention discloses a waterborne polyurethane / amino organosilicon compound resin which can be used as a fabrics softening finishing agent. The compound resin contains 45 to 60 portions of polyester glycol, 20 to 40 portions of toluene diisocyanate, 1 to 10 portions of dihydromethyl propionic acid, 5 to 15 portions of amino organosilicon intermediates, 0.02 to 1.0 portion of catalysts, 1 to 10 portions of triethylamine, 10 to 50 portions of diluents and 200 to 500 portions of deionized water by weight portions. After being processed by the waterborne polyurethane / amino organosilicon compound resin prepared by the invention, fabrics have better handling and softness and higher tearing strength.

Description

technical field [0001] The invention relates to a water-based composite resin, in particular to a water-based polyurethane / amino silicone composite resin which can be used as a fabric softening and finishing agent. Background technique [0002] Amino silicon emulsion (water-based amino silicone resin) can be used as a fabric softening and finishing agent in the textile field, and is one of the most used finishing agents at present. Its excellent properties are widely used in post-treatment of cotton, linen, silk, wool, polyester, nylon and acrylic fabrics to obtain soft, smooth and plump hand feeling. However, there are three main problems in common amino silicone emulsions: (1) easy yellowing; (2) poor adhesion to fabrics; processing effect. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a water-based polyurethane / amino silicone composite resin, which overcomes the shortcomings of the existing emulsion finish...
