Abstract

The invention relates to a method for preparing normal-temperature normal-pressure dyeable polyester pearl fiber, which comprises the following steps: (1) shearing and grinding pearls to obtain crude pearl powder, then mixing the crude pearl powder and water according to the weight ratio of 1: 10-100, crushing the mixture to obtain a water dispersion of the pearl powder, adding a thermal stabilizer, an antioxidant and an emulsifying agent into the water dispersion of the pearl powder, and performing drying treatment; (2) mixing the obtained product evenly with a compatilizer at normal temperature according to the weight ratio of 1: 0.1-0.5, then adding the mixture into normal-temperature normal-pressure dyeable polyester chips, performing granulation on the mixture by a double screw extruder, and obtaining nano-pearl polyester chips, wherein the weight content of the mixture in the normal-temperature normal-pressure dyeable polyester chips is between 10 and 30 percent; and (3) blending the nano-pearl polyester chips and the normal-temperature normal-pressure dyeable polyester chips for spinning. The method can be finished on the prior spinning equipment, tows are irregular, and have evenly distributed color and luster after the dying; fabric is smooth, and has the characteristic of soft luster; and the method can be widely applied in the fields of apparel, decoration and industry.

Description

technical field [0001] The invention belongs to the field of preparation of pearl fibers, in particular to a preparation method of dyeable polyester pearl fibers at normal temperature and pressure. Background technique [0002] Normal temperature and pressure dyeable polyester pearl polyester fiber can be made into high-grade textiles that are soft to the touch and comfortable to wear, and have high economic value. Pearls contain a variety of amino acids and trace elements. Therefore, the development of nano-pearl polyester fiber manufacturing technology is a high-tech that functional fibers have paid attention to in recent years. [0003] Due to the good economic value of pearl functional fiber, there are many companies researching similar products. Authorized notification number CN100368611C discloses a pearl composite fiber and its manufacturing method. The pearl composite fiber is formed by blending and copolymerizing hydrolyzed pearls and polyvinyl alcohol, but it is ...
