Abstract

The invention provides a degreasing and shrinking method of PTT and common polyester blended fabrics and its application. The degreasing and shrinking method comprises: putting PTT and common polyester blended fabrics into a penetrating agent and a degreasing agent, and putting the system Raise the temperature to 85-95°C at 0.4-0.6°C / min, raise the temperature to 105-115°C at 0.8-1.2°C / min, keep warm for 5-15 minutes, and cool down to 40-60°C to complete the PTT and ordinary polyester blended fabric. Degreasing and shrinking: The textile fabric obtained by the above degreasing and shrinking method has good tensile resilience, excellent dyeability, high bulkiness and wear resistance, and has important research value.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a method for deoiling and shrinking PTT and ordinary polyester blended fabrics and its application. Background technique [0002] The existing dyeing and finishing general process is followed by pre-relaxation, setting, dyeing and finishing steps; in the process of spinning, drawing and weaving of textile fibers, in order to increase the smoothness of fibers, reduce the friction between fibers and between fibers and machines, To improve fiber cohesion, protect fiber strength, and reduce yarn breakage rate, a large amount of spinning oil should be added during the weaving process. In order to ensure the dyeing performance of the fiber and prevent the appearance of color flowers, color lakes and silicone oil spots, it is necessary to add a degreaser to the fabric before dyeing to remove the oil and oil stains on the cloth surface. PTT is commonly known as elastic poly...
