Composite down material and preparation method and application thereof

Abstract

The invention provides a composite down material and a preparation method and application thereof. The composite down material includes down and graphene-modified short fibers uniformly dispersed in the down. The provided composite down material has great antibacterial performance, far-infrared performance and anti-static performance; meanwhile, the graphene-modified short fibers and the down canbe supported by each other, more air storage space is provided, and therefore the composite down material has heat preservation performance. Moreover, down is likely to generate static electricity because of mutual friction and thus agglomerate together, and the graphene-modified short fibers contain graphene, have an antistatic function and can counteract the static electricity generated by the friction of the down to alleviate the agglomeration problem.

Description

technical field [0001] The invention belongs to the technical field of textile and chemical fibers, and relates to a down composite material and its preparation method and application. Background technique [0002] Natural down as a thermal insulation material has long been recognized by humans, and in 1940 Eddie Bauer obtained the first quilted down jacket patent, pioneering the application of natural down as a thermal insulation material in clothing. Down is mainly derived from the abdomen of waterfowl animals, geese and ducks. It is a kind of animal protein fiber. The down ball-shaped fiber is densely covered with tens of thousands of small triangular pores, which can shrink and expand with temperature changes, produce temperature regulation function, and absorb human body. The flowing hot air blocks the invasion of cold air from the outside. Compared with cotton, wool and silk natural insulation materials, it has the best thermal insulation performance. At present, down...

Problems solved by technology

[0003] Although people are very fond of the thermal performance of down, there are many defects in the existing technology. For example, down itself belongs to a kind of animal protein fiber, which is easy to breed bacteria and mildew in a humid environment; At the same time, European and American countries prohibit the use of "live plucking" in order to protect animals, which makes the cost of down use too high; the down itself is relatively dry and prone to static electricity, which brings a lot of inconvenience to people during use; therefore, the development of Down-like thermal insulation materials with comprehensive properties close to natural down and which can improve the defects of natural down have broad application prospects

[0004] At present, there are many reports on the research on thermal insulation materials of down mixtures. CN104195665A discloses a composite down composite fiber made of waste down fiber/acrylic short fiber and a manufacturing method thereof. -15 parts, 20-25 parts of waste down fiber, 25-30 parts of nano g
