Problems solved by technology
[0011] However, the existing spherical fiber aggregates only have a negative thermal insulation effect achieved by relying on the air content ratio. Since they need to be prepared through many processes, there is a problem that the original fiber color, that is, the whiteness, will be greatly reduced after the process. The size of the fiber aggregate is not uniform and the density is high, which causes the problem that the advantages of the spherical shape are destroyed in terms of air content and recovery.

Embodiment
[0100] 1. Preparation of spherical photothermal fiber aggregates
[0101] 10% by weight of polyester staple fibers with a fineness of 2.5 denier and a fiber length of approximately 22 to 32 mm and 90% by weight of side-by-side hollow composite fibers with a fineness of 3 denier and a fiber length of approximately 28 to 40 mm fiber as staple fiber.
[0102] The short fiber is opened for the first time by using a fiber opener with a pin spacing of 8.3mm and formed by 4 rollers, using a wind pressure of 140mmAq and an air volume of 50m 3 The wind power of / min is used to carry out the first fiber mixing, after the short fibers are separated and stacked into 7cm, the mixture mixed with the light-emitting substance (ATO) and the adhesive is sprayed through the spray nozzle with a nozzle pressure of 0.6MPa, so that the The light-heating substance is coated on the short fiber.
[0103] Under the hot air of 140 ℃, the short fibers coated with the light-emitting substance were dried ...

Abstract
The invention provides a spherical photo-heating fiber aggregation which is prepared by spraying and coating one or more of a polyamide short fiber, a polyester short fiber and a polypropylene short fiber with a photo-heating substance; and then performing splitting and blending to separating the short fibers and forming spheres. The photo-heating substance is a mixture composed of any one or more than two of ATO, ITO and IV-group metal oxides, whiteness being 90-99%.
Description
technical field [0001] The present invention relates to a spherical light-heating fiber assembly, and more specifically, to a spherical light-heating fiber assembly excellent in heat retention and whiteness by using a highly transparent light-heating substance and using the same fiber insulation material. Background technique [0002] With the popularity of outdoor clothing, everyone can take out at least one goose down or duck down jacket to wear in order to maintain body temperature when the cold wind blows. Outdoor clothing products have penetrated into our lives. With a correct understanding of outdoor products and other information, we began to look for outdoor products with functions more suitable for daily life than high-end products with high functionality and thermal insulation for extreme environments. Keeping up with this consumption trend, among the outdoor products for winter that are being developed recently, outdoor products that are thin, light, and have hig...
