Abstract
Hollow abnormal fibers are produced with special spinning jets. The fibers have abnormal cross section with 1 to 17 hollow orifices on. Spinneret holes comprises ' C' shape annular holes to form hollow orifices in the center of the abnormal fibers which is spurt out and produced by post works. The jet-spinning nozzle comprises 1 to 17 'C' shape annular hole. The hollow abnormal fibers can quickly absorb water, deliver water, spead and volatile to make clothes feeling well and dry. It improves the expanded and floppy, with natural hand-feeling. The fibers have high capillary and air permeability, core suction capability is high over the general abnormity fiber textiles. The hollow abnormal fiber' s surface is shiny, good moisture absorption, well perspiration capability, floppy and hand-feeling.
Description
Technical field the present invention relates to the production method of a kind of heterotypic fibre, heterotypic fibre and produces special spinning jet, specifically a kind of hollow heterotypic fibre and production method thereof and production special spinning jet.
Background technology is along with increasing of synthetic fiber new capability and improving constantly of added value, and textiles and the industrial goods made by synthetic fiber more and more are subjected to liking of people.But the synthetic fiber that general melt spinning is made because its structural form is more single, are compared with natural fabric, still are that performance still has suitable gap from structure no matter.At present, its shape of cross section of the heterotypic fibre of producing on the market mainly contains triangle, three leaves, pentagon, cross, pancake, C shape, T shape etc., shown in Fig. 1-1 and Fig. 1-2 is exactly the cross section of existing common heterotypic fibre, its shape is fairly simple, and the fiber surface low in glossiness exists easily dirty, easy balling-up, water imbibition is poor, shortcomings such as bulkiness is poor, and feel is poor, and elasticity is little.And the hygroscopic fibre on the present market, how based on cotton fiber, polyester fiber is only also to be common special-shaped long filament.Have only 4 capillary channels (being 4 formed grooves in angle in fact) in the cross section of the cross fiber shown in Fig. 1-2, the moisture absorbing and sweat releasing poor-performing.
It is good that summary of the invention technical problem to be solved by this invention is to propose a kind of fiber surface glossiness, and moisture absorbing and sweat releasing, bulkiness and feel be hollow heterotypic fibre and production method thereof and production special spinning jet preferably all.
For solving the problems of the technologies described above, the shape of cross section of hollow heterotypic fibre of the present invention is special-shaped, and its cross section is provided with mesopore, and the quantity of described mesopore is 1 to 17.
Above-mentioned hollow heterotypic fibre, set mesopore is entad type arrangement on its cross section.
The production method of above-mentioned hollow heterotypic fibre, its production stage comprises: raw material screening, raw material drying, high-temperature fusion, screw rod is extruded, the spinnerets ejection, cooling oils, and is shaped to reel drawing-off and finished product, the spinneret orifice of the spinnerets that adopts is combined by the hole of " C " type ring-type, makes the centre of the heterotypic fibre that is shaped through its ejection and through the postorder operation can form mesopore.
Be used to produce the production special spinning jet of above-mentioned hollow heterotypic fibre, its spinneret orifice is combined by the hole of a plurality of " C " type ring-type, and the quantity of set mesopore is identical on the quantity in " C " type hole and the hollow heterotypic fibre cross section, is 1 to 17.
Above-mentioned hollow heterotypic fibre is produced special spinning jet, and the arrangement mode of described " C " type annular aperture is type entad.
Above-mentioned hollow heterotypic fibre is produced special spinning jet, and described spinnerets is provided with a plurality of spinneret orifices that combined by described " C " type annular aperture.
The present invention at high temperature extrudes fibrous raw material earlier during production owing to adopted the production special spinning jet of aforementioned production method and above-mentioned technical pattern from spinnerets, cooling curing then, and drawn forms fiber.That comes out from " C " type hole of spinnerets melts body, according to expanded principle with melt the body rheology principle, from the hole after the ejection promptly around the hollow heterotypic fibre that the space is arranged in the middle of forming, and the shape of " C " type hole assembled arrangement is exactly the global shape of strand cross section.Because the present invention imports textile development with natural capillary theory, make the capillary that can be formed up to many 17 passages in the fiber, thereby suction fast, water delivery, diffusion and volatilization, thereby keep the dry and comfortable of skin.The cross-sectional area coverage rate of hollow heterotypic fibre of the present invention is between 70%-80%, under the identical situation of fiber quality (weight), the common heterotypic fibre of surface area ratio increases 20%-30%, thereby improved the bulkiness of fiber greatly, elasticity makes fiber that the feel of natural fabric be arranged, and capillary effect and gas permeability are very high, wicking capacity substantially exceeds common heterotypic fibre textiles, more surpasses cotton.Fig. 9 and Figure 10 have promptly shown the moisture pick-up properties and the diffusion effect of the excellence that hollow heterotypic fibre of the present invention is had.The lining that is made into by hollow heterotypic fibre of the present invention, quality is slim and graceful, be through on one's body and can give smooth, ventilative, comfortable sensation, and fabric need not special processing, Machine Washable and oven dry are used very extensively, can be used for producing dress ornaments such as shirt, jacket, Training wear, underwear, be used in particular for Defence Force and make military clothes, to adapt to the requirement of army's operation under some adverse circumstances.
