Abstract
The utility model provides hollow fiber, which is characterized in that the cross section of the fiber is in a regular octagon shape comprising a concentric circle, and the radius of the concentric circle is half of the radius of an inscribed circle of the regular octagon, wherein the inside of the circle is hollow, the rest part is a fiber entity, and the whole body of the fiber is in a linear state. The octagon-shaped hollow fiber has the performance of heat insulation, fluffy effect and the like of hollow fiber, and at the same time, surface materials obtained through spinning can realize the polyhedron reflecting effect under the irradiation of light rays.
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 octahedral build doughnut.
A kind of doughnut, the cross section that it is characterized in that fiber is for including concentrically ringed positive all directions shape structure, and concentrically ringed radius is 1/2 of a positive shape inscribed circle radius from all directions, and wherein circular interior is a hollow, and remainder is the fiber entity, it is linear that fabric integer is.
The beneficial effects of the utility model are this kind octahedral build doughnuts, and when possessing performances such as doughnut is warming, fluffy, the lining that obtains by weaving has the polyhedron reflecting effect under the shining of light.
Description of drawings
Accompanying drawing is the sectional view of doughnut.
Wherein: 1, outer tangent plane; 2, the fiber entity; 3, open circles.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
In the specific implementation process, can utilize melt spinning method that chemical fibre kind polyester or polyamide are carried out spinning, obtain octahedra hollow type fiber, the cross section of fiber is the positive all directions shape that includes open circles 3, and concentrically ringed radius is 1/2 of a positive shape inscribed circle radius from all directions, wherein circular interior is a hollow, remainder is a fiber entity 2, and it is linear that fabric integer is, and has reasonable effect of heat insulation like this, and because fiber has eight smooth smooth outer tangent planes 1, fiber possesses reflecting effect simultaneously.
In concrete the application, effect of heat insulation improves about 12% than general circular concentric.
Claims (1)
1. doughnut, the cross section that it is characterized in that fiber is for including concentrically ringed positive all directions shape structure, and concentrically ringed radius is 1/2 of a positive shape inscribed circle radius from all directions, and wherein circular interior is a hollow, and remainder is the fiber entity, it is linear that fabric integer is.
