Fabrics finished with amino-modified polyether silicone oil (especially cotton fabrics) still retain good hydrophilicity and achieve high wrinkle resistance and super smooth feel. Adding it to the dyeing agent allows the reactive dye and the direct dye to not fade when the fabric is wet and dry. The treatment of the fabric or fiber with an amino group-modified polyether silicone oil containing an ester group allows the fiber fabric to be both ultra-soft and hydrophilic. Polyether silicone oil containing arylamino group has higher heat resistance than ordinary polyether silicone oil, and is suitable as high temperature resistant fiber oil agent or resin additive. If it is added to ordinary polyether modified silicone oil, it can improve polyether. The heat resistance of silicone oil. The organosilicon copolymer containing epoxy group, amino group and polyether is easily soluble in water, can form a lake with water-soluble dye, can be enriched and formed on the surface of the fiber; has a sliding effect, can reduce the surface friction coefficient of the fiber It can significantly improve the dry and wet rubbing color fastness of the fabric; it can also make the dyed product after fixing has no color change problem, and still maintain the breathability of the fabric and the soft hand taking performance. The fabric prepared by the amino group and the epoxy group co-modified polyether silicone oil has extremely low surface tension, and the contact angle with water is more than 150 ° C, showing superior hand feeling, and has good flexibility, fluffiness and slip. Sleek, can be repaired, not yellow. The carboxyl group-modified polyether silicone oil containing ester group has good dispersing effect on disperse blue dye, and can prevent dye re-aggregation when dyeing at high temperature; and phosphate ester modified polyether silicone oil has good lubricity and antistatic property to fiber.
