Abstract

The invention provides an organosilicon emulsion used for the hand feel finishing of wool and blended yarn thereof, which comprises 40 to 60% of amino silicon oil emulsion, 30 to 50% of hydroxy silicon oil emulsion and 10% of hydrogen-containing silicone oil emulsion. A preparation method comprises the steps of preparing the amino silicone oil emulsion, the hydroxy silicon oil emulsion and the hydrogen-containing silicone oil emulsion, and then mixing according to the proportion of 40-60%, 30-50% and 10%. The application comprises putting the wool or the blended yarn thereof into the organosilicone emulsion, soaking at the temperature of 40-45 DEG C for 30-60 minutes and drying at the temperature of 85-100 DEG C after dehydration. The effect of the comprehensive hand feeling of smoothness without grease, softness, overhang feel, slip and bulkiness is achieved.

Description

technical field [0001] The invention relates to a silicone emulsion, its preparation and application, in particular to a silicone emulsion for hand finishing of wool and its blended yarn, and its preparation and application. Background technique [0002] Amino silicone oil is mainly used as a softener in the finishing of fabrics. Due to the polarity of the amino group, it can cross-link with the hydroxyl group and carboxyl group on the surface of the fiber, so that the main chain of the siloxane is directional adsorbed on the surface of the fiber, thereby reducing the friction coefficient between the fibers, and it can be made with a small force. Sliding occurs between the fibers, thereby exhibiting soft properties. Generally speaking, the fabric treated with amino silicone oil emulsion has a soft, smooth and plump feel, and has good shrink resistance, washability and air permeability. [0003] In recent years, mercerized wool and wool-feel finishing emulsions have become ...
