Abstract
The utility model provides a porous hollow fiber which is characterized in that the outer layer of a fiber is circular, the cross section of the fiber is a two-layer structure, namely an inner circle and an outer ring, wherein the inner circle comprises four 90 degrees of hollow fan shapes, 15-60 hollow small circles are arranged in the outer ring, the other portions are fiber solids, the fiber is integrally in line shape, then, a porous hollow fiber is got, and the thermal insulation and the flexibility of the hollow fiber can be improved.
Description
Technical field
The utility model relates to a kind of spinning fibre, especially relates to a kind of doughnut.
Background technology
The general good natural fabric of thermal property, for example wool, kapok, eider down etc. all have cavity, particularly kapok, and degree of hollowness is up to 70%.General chemical fibre is normally solid, and warmth retention property is also just very different.Macromolecule melt through extraordinary slit spinnerets sprays can obtain doughnut after the cooling.Doughnut have dangle, good heat preservation performance, bulkiness is good, resilience is good, to the allergic reaction of human body thing, to wash fast advantage such as do, with doughnut as material can make clothes, by multiple products such as wadding, pillow, winter protection articles, very popular.
But the kind of doughnut is not a lot, needs further development of new doughnut, satisfies the needs of spinning.
Summary of the invention
In order to overcome the less problem of kind of existing doughnut, the utility model provides a kind of porous hollow fiber, improves the heat insulating ability and the flexibility of doughnut.
A kind of porous hollow fiber is characterized in that fibrous outer is rounded, circle and outer shroud double-layer structure in the fibre section is divided into, and interior circle comprises the hollow fan-shaped of 4 90 degree, and 15～60 hollow roundlets are arranged in the outer shroud, and remainder is the fiber entity, and it is linear that fabric integer is.
Be spun into cylinder cross section porous hollow fiber, form stable hollow space, all the other are entity, obtain porous hollow fiber like this, can improve the heat insulating ability and the flexibility of doughnut.
Description of drawings
Accompanying drawing is the cross section structure figure of porous hollow fiber.
Wherein: 1, hollow fan-shaped; 2, open circles; 3, the fiber entity.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified: when utilizing melt spinning method that technologies such as polyester or polyamide are carried out spinning, adopt corresponding spinnerets to spin circular fiber, its inner circular part branch comprises 4 hollow fan-shaped 1, outer ring portion comprises 15～60 open circles 2, and all the other are fiber entity 3.
Porous hollow fiber like this, utilize melt spinning method that polyester or polyamide are carried out spinning, can also be spun into cylinder cross section porous hollow fiber, this kind has two concentric circles of size on the cross section of fiber, little radius of a circle is 1/2 of a great circle, the pintongs style shape that an inscribe is arranged in roundlet, annulus part at great circle and roundlet composition, be evenly distributed 8 melon seeds shapes, it is hollow space that the pintongs style shape and the melon seeds shape in the annulus of an inscribe are arranged in the roundlet, all the other are entity, and it is linear that fabric integer is, and obtains porous hollow fiber.
In the practical application, such porous hollow fiber is to improve 15～50% heat insulating abilities and the flexibility of doughnut.
