Eider down is well natural heat insulating material formed, has been widely used in to make down jackets, bedding and tame spun articles.Eider down is a shape, the tapered body of core, and to dispersing all round, its natural physical arrangement has determined its goods to have characteristics such as bulking intensity height, good springiness, good permeability and warmth retention property are good to staple from core.But eider down exists, and cost height, output are restricted, poor durability, easy defective such as go mouldy, and easily bore hair, and the density requirements height is expected in the inside and outside.

In recent years, external some fibre company has successively released imitative natural crimp polyester staple fiber series of thin dawn as novel packing material.Because fibre fineness is thin, flexibility is good, and low, the smooth degree of bending strength is high, when the fine diner silicon-containing polyester short fiber is used for packing material, can reach moderate like cotton warming, comfortable softness, bulking intensity, can solve cost of material reduction, squeezable shortcoming again.But pure fine diner silicon-containing polyester short fiber is as packing material, and light and thin degree, gas permeability, warmth retention property, bulking intensity and eider down are compared or many gaps are arranged.

Summary of the invention

The purpose of this utility model provides a kind of Down-like Material, to overcome the above-mentioned defective that prior art exists.

Novel Down-like Material of the present utility model by constituting as the spherical polyster fibre of core and the fine diner silicon-containing polyester filament that is wrapped in outside the core, is similar to a three-dimensional shape structure of eider down.

The utility model is used for bedding filling pillow, bed clothes, sleeping bag and march quilt etc. because of its particular performances is very suitable for substituting eider down, is fit to do high-grade insulation garment, high-grade liner, and can cleans indeformable.

The utlity model has soft feel as the eider down, remarkable heat insulating ability and light weight sense, good fluffing effect, be easy to surface treatment, outstanding feel slippery, good gas permeability, hygroscopicity, warmth retention property, both frivolous and the compression and back renaturation is good; And overcome the defective that eider down bores hair, and reduced requirement to lining, lining, also can improve the harmonious relationships of Man ﹠ Nature simultaneously greatly.
