Abstract
The utility model relates to hollow fiber. The hollow fiber is characterized in that each silk section of a bunch of silk is of a circular ring shape with bulges, the interior of the silk section is hollow, the bulges on the circular ring are 4-6 small half circles which are uniformly distributed on the circular ring, and the diameters of the small half circles are 0.10-0.14 mm; the ratio of the inner radius and outer radius of the circular rings is 1 to (1.1 -1.3); the filament number of the fiber is 0.3dtex-1.5dtex, and the hollow degree of the fiber is 10-50%; and the fiber comprises filament fiber and short fiber, wherein the filament fiber comprises POY(pre-oriented yarn), FDY (fully drawn yarn) and DTY (drawn textured yarn). The hollow fiber provided by the utility model has the advantages that the heat retention is good, the hollow degree is large, the hollow fiber has a good moisture absorption and sweating function, and the hollow fiber is suitable for processing and producing mesh liners of high-end thermal underwears, winter clothes, sportswears, overcoats, overdress, underclothes, night suits, business suits and the like.
Description
Technical field
The present invention relates to a kind of synthetic fiber, specifically is a kind of doughnut.
Background technology
Cross sectional shape that the general fibre cross section is rounded, solid and structure lack good suction, moisture pick-up properties, and regain is merely 0.4%; About fracture strength 5.0CN/dtex, extension at break 20～30%, initial modulus reaches 1.10cN/dtex; Demonstrate the wet comfortableness of relatively poor heat; In high humidity, the condition of high temperature, can make the people that feeling of oppression and heat is arranged by this twice-laid clothes, mood is had the fidgets; Lack good sense of touch comfortableness, skin-friendly is relatively poor.
Natural fabrics such as general kapok, wool, eider down have cavity, and the spy is kapok fully, and degree of hollowness is up to 70%.Manufacturing has emulation mode with the doughnut in the close cross section of natural fabric by extensive employing.This is because odd-shaped cross section makes appearance profile be irregular, makes polyester textile that fluffy sense arranged, and has improved gloss effect and feel, has improved fabric breathability, PILLING RESISTANCE.Hollow structure has reduced quality of fiber, has improved the heat-insulation warm keeping property of fabric.Compare with single round doughnut, profiled filament and to have more superiority; Fabric with this fiber making; Its bulkiness is big by 15～20% than common fabric; And anti-wear performance is higher 2 times than common circular fiber, with doughnut as material can make clothes, by multiple products such as wadding, pillow, winter protection articles, very popular.
Summary of the invention
The utility model purpose provides a kind of doughnut, and fabric good warmth retention effect, fluffy sense are well, the moisture absorbing and sweat releasing performance is good, improved fabric breathability, PILLING RESISTANCE, and be very popular.
A kind of doughnut is characterized in that every rhizoid cross section of a synnema all is the protruding toroidal of band, and inside is hollow.Convexity on the said annulus is 4～6 small semicircles, is evenly distributed on the annulus, and diameter is 0.10～0.14mm.
The ratio of the interior outer radius of described annulus is about 1: 1.1～and 1.3.
Described doughnut, wherein, the filament number of said fiber is 0.3dtex～1.5dtex.
Described doughnut, wherein, the degree of hollowness of said fiber is 20～50%.
Described doughnut, wherein, said fiber comprises filament fiber and staple fibre.
Described filament fiber comprises POY, FDY and DTY.
The doughnut of the utility model, warmth retention property is good, and degree of hollowness is big, can with warm air tank in fiber, fully isolate cool ambient air; Raised channel around the moisture absorption sweat discharging functions that height is arranged, fiber can direct into fabric face in time with moisture, the sweat that human body produces, and makes the people feel pleasant; Made clothes are not only light but also soft, because arcuate furrow is arranged, therefore very soft sense of touch arranged around the fiber.The doughnut of the utility model is fit to the mesh lining of the high-grade cold-proof underwear of processing, winter dress, sportswear, overcoat, coat, shirt, nightwear and Western-style clothes etc. etc.
Description of drawings
Fig. 1 is the utility model schematic cross-section.
The specific embodiment
Below in conjunction with embodiment the utility model is at length explained.
Embodiment 1
A kind of hollow FDY polyester filament, product specification are 30D/24F.This fiber is the protruding hollow structure of band, and degree of hollowness is 45%, and 5 protruding circular arcs of outline distribution form a plurality of grooves.Use the take-up winding facility of Barmag AG, melt Direct Spinning ring blowing cooling technology adopts one-step method FDY process route to produce.Spin the 30D/24F degree of hollowness and be 45% hollow FDY polyester filament.
Embodiment 2
A kind of hollow polyester low-stretch yarn, product specification are 50D/24F.This fiber is the protruding hollow structure of band, and degree of hollowness is 40%, and 6 protruding circular arcs of outline distribution form a plurality of grooves.Use the take-up winding facility of Barmag AG, TMT company adds bullet equipment, and melt Direct Spinning ring blowing cooling technology adopts two step method DTY process route to produce.Spin the 50D/24F degree of hollowness and be 40% hollow DTY low elastic polyester filament.
Through experiment showed, the hollow polyester fiber of the utility model, solved the warming problem of frivolous clothes, remedied that Warm-keeping garment is ventilative leads moist relatively poor deficiency.
