Problems solved by technology

[0004] Knitted fabrics obtained by adding cooling additives in the finishing process of fabrics have poor washability, and the cooling effect of the fabrics will be weakened after repeated washing. In addition, the cooling additives will mix with other additives during the finishing process. drug interactions leading to insignificant or weakened effects
[0005] For fibers with cooling effects such as jade fiber, in order to achieve a sufficient cooling effect, a large amount is added, resulting in poor fiber strength, insufficient comfort, and problems such as powder dropping and peculiar smell; not feeling enough

Embodiment 1

[0052] A kind of cool feeling fiber, preparation method comprises the steps:

[0053] (1) Preparation of functional particles containing graphene materials:

[0054] The biomass graphene powder and the polyester chip were dried separately; the graphene powder was vacuum-dried at 105°C for 12 hours; the polyester chip was dried at 80°C, 100°C, 120 ℃ for 1 hour each, and finally at 140 ℃ for 6 hours; the moisture content of the polyester chips after drying is 30ppm-120ppm;

[0055] Afterwards, 10wt% biomass graphene powder (particle size is below 3 μm) and 90wt% dried polyester chips are pelletized to make functional particles containing graphene material through a twin-screw extruder, and pelletized The temperature is 260°C;

[0056] (2) Preparation of functional granules containing jade powder:

[0057] The flaky jade is micronized so that the particle size is between 100nm and 500nm to obtain a cool powder; the cool powder and polyester chips are dried separately; the cool...

Embodiment 2

[0061] The difference with Example 1 is that the mixing ratio of functional particles containing jade powder and functional particles containing graphene material and regenerated polyester chips in the adjustment step (3) obtains graphene material in fiber content 0.3wt%, jade The powder has a cool feeling fiber with a content of 1wt% in the fiber.

Embodiment 3

[0063] The difference with Example 1 is that the mixing ratio of functional particles containing jade powder and functional particles containing graphene material and regenerated polyester chips in the adjustment step (3) obtains graphene material in the fiber content 0.2wt%, jade The cooling fiber with a powder content of 2wt% in the fiber.

Abstract

The invention relates to a cool fiber preparation method. The cool fiber preparation method includes: (1) mixing graphene materials with a first fiber substrate, and extruding to obtain graphene material-contained functional masterbatches with a screw; (2) mixing jade powder with a second fiber substrate, and extruding to obtain jade powder-contained functional masterbatches with a screw; (3) mixing the graphene material-contained functional masterbatches, the jade powder-contained functional masterbatches and a third fiber substrate to obtain a mixture, blending, fusing and spinning to obtaincool fibers. By adding the graphene materials and the jade powder into fiber materials, cool effect is improved, on the premise that same requirement on the cool effect is satisfied, additive amountof the jade powder can be decreased, and the problems of poor comfort, powder falling, peculiar smell and the like of the fibers, caused by excessive addition of the jade powder, are solved.

Description

technical field [0001] The invention belongs to the field of fiber preparation, and relates to a cooling fiber, a preparation method and application thereof. Background technique [0002] At present, the general realization methods of contact cool polyester fabrics on the market are as follows: [0003] ①Mix and spin a substance with a cooling effect with polyester chips to form a filament with a cooling effect, such as jade fiber, and then make a fabric; ②Add a cooling agent in the finishing process of the fabric, such as Xylitol-based cooling additives are used for post-finishing to obtain a cooling effect; ③The yarn hairiness is reduced by compact spinning, thereby reducing its warmth retention effect and obtaining a cooling effect. [0004] Knitted fabrics obtained by adding cooling additives in the finishing process of fabrics have poor washability, and the cooling effect of the fabrics will be weakened after repeated washing. In addition, the cooling additives will mi...
