[0027] Numbering Pearl powder Heat stabilizers, Antioxidants Emulsifier

[0028] Prepare a suspension, set the pressure of the high-pressure homogenizer to 120MPa, add the suspension to the feeding tank of the high-pressure homogenizer, automatically feed, and obtain pearl powder with a particle size of 50-100 nanometers after high-pressure crushing The suspension is heated and dried to obtain a pearl powder composite with a particle size of 50-100 nanometers.

Embodiment 2

[0030] Preparation of nano-pearl polyester superfine denier slices After mixing 20 parts by weight of nano-pearl powder composite obtained in Example 1 and 7 parts by weight of polybutylene terephthalate at normal temperature, the above-mentioned mixture was added to 73 parts of polyester chips were granulated by a twin-screw extruder to obtain nano-pearl polyester chips.

[0031] Slicing and granulation process parameter unit: ℃

[0032]

Embodiment 3

[0034] Preparation of colored pearl polyester fibers with nano-pearls The nano-pearl polyester slices obtained in Example 2 were subjected to high-speed spinning according to the spinning process requirements. The melt temperature for spinning is controlled between 255 and 310°C. Polyester chips are produced by Jinshan Petrochemical.

Abstract

The invention relates to a method for preparing nano-pearl colored polyester fiber, which comprises the following steps that: (1) pearls are sheared and ground to obtain crude pearl powder, then the crude pearl powder is mixed with water, a water dispersion of the pearl powder with a grain diameter of between 50 and 100 nm is obtained through high-pressure crushing, a thermal stabilizer, an antioxidant and an emulsifying agent are added into the water dispersion of the pearl powder, and the drying treatment is performed; (2) the obtained product is mixed evenly with a compatilizer at normal temperature, then the mixture is added into polyester chips, and granulation is performed on the mixture by a double screw extruder; and (3) nano-pearl polyester chips, the polyester chips and color master batch are blended for spinning. The method can be finished on the prior spinning equipment, tows are even and have evenly distributed color and luster; fabric is smooth, and has the characteristic of soft luster; the method is widely applied in the fields of apparel, decoration and industry; and at the same time, the blended color master batch can be used for preparing fibers with various lusters, and the prepared fibers have good nutrition and health care effects on human bodies.

Description

technical field [0001] The invention belongs to the field of preparation of pearl polyester fibers, in particular to a preparation method of nano pearl colored polyester fibers. Background technique [0002] Colored 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 have the effects of nourishing skin and skin, clearing fire and detoxification, whitening skin, and resisting ultraviolet rays. Pearls contain various amino acids and trace amounts element. 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 blen...
