Abstract
The utility model provides a sixteen hollow three-dimensional crimped fiber. The size of the sixteen hollow three-dimensional crimped fiber or short fiber is from 3.3 to 55 dtex. The sixteen hollow three-dimensional crimped fiber of the utility model has high hollowness, excellent fluffiness, better resilience and stronger warmth retention property, which is comfortable to the feel.
Description
Technical field
The utility model relates to a kind of hollow profiled fibre, and specifically, the utility model relates to the 16 hollow 3-D crimped fibers that a kind of its cross section is 16 hollow shape.
Background technology
Single hole, or porous, and particularly the three-dimensional crimp staple fibre of porous has that fluffy excellent performance, rebound performance good as degree of hollowness height, the eider down are good, thermal property reaches advantages such as feel is smooth by force.The synthetic fiber of hollow three-dimensional crimp also have general fibre convenient sources, cheap, the advantage of not damaging by worms and going mouldy, it is a kind of desirable fibrefill material, replace artificial fibre and natural fabric, making pillow, mattress, sleeping bag, ski-wear, sofa cushion, soft toy etc.Thereby the three-dimensional crimp staple fibre of porous is specially adapted to as cloth art packing material, bunting, supatex fabric, carpet, wool-like fabric and filtering material etc.For this reason, up to now, existing multiple single hole or porous three-dimensional crimped staple come out.
For example, application number is the fiber spinneret that the Chinese patent of " the high degree of hollowness 3 D stereo crimped fibre spinnerets " of " 92244356 " discloses a kind of single hole hollow, uses this spinnerets to spin and obtains a kind of single hole doughnut.Application number discloses a kind of spinning equipment and spinning process thereof of single hole hollow polymer fiber for the Chinese patent of " spinning equipment of hollow polymer fiber and the method " of " 9619836 ", according to described spinning equipment and spinning process thereof, can spin the single hole doughnut that obtains a kind of hole wall densification.In addition, application number discloses a kind of spinning process of single hole hollow activated carbon fiber for the Chinese patent of " preparation method of hollow activated carbon fiber " of " 95119030 ", thus, spinning obtains single hole doughnut carbon containing, that can be used for fields such as catalysis, medicine, electronics liquid phase adsorption.But said method or spinnerets can only spin and obtain the single hole doughnut.
Again, application number has then been introduced a kind of the spinning for the Chinese patent of " Six-hole spinnerette " of " 96220288 " and has been obtained the polyester staple fiber that its circular cross-section is essentially six holes.
Du pont company has also been developed fibrefill fiber of new generation, it is polyester staple fiber to be made four hole hollows (commodity are called Hollofil II, specification is that 6dtex * 51mm) (commodity are called Quallofirm with the seven apertures in the human head doughnut, specification is 6dtex * 51mm), the surface coverage organosilicone film of these fibers, can reduce scroop, feel is smooth, and the laudatory title of super eider down and breathing cotton is arranged.At home, Yizheng Fiber Optical plant and Heilungkiang terylene factory have introduced Japanese Japan spinning technique and have formed certain production scale.
Again, application number is " 02215538.4 ", denomination of invention has then been introduced a kind of synthetic fiber or staple fibre and spinning spinnerets thereof that obtains nine hole hollow form three-dimensional crimps that spin for the Chinese patent of " nine pass three-dimensional crimp synthetic fiber and spinnerets thereof ", described fiber has preferable binding site between the hollow hole count of fiber and fibre number, three-dimensional crimp degree and product requirement, and has the processing characteristics and the price/performance ratio thereof of excellent product.Described utility model ties up to the spinneret orifice that forms eight breach annulars or T font on the spinnerets around the part all around at its center, high-temperature fusion is made spinning melt extrude from 16 hole spinneretss, forms the melt jet; When the spinning melt jet left spinnerets, the cold wind air-flow quenching with low-temperature and high-speed became as-spun fibre; The as-spun fibre drawn bathed stretch, oil, after the operation such as dryness finalization, finally form the synthetic fiber of nine hole hollow form three-dimensional crimps of this utility model.Described synthetic fiber make it have advantages such as better degree of hollowness, fluffy performance, rebound performance, thermal property and even water vapour permeability because of its crimpness that has and nine pass fibre structures.
Yet the hollow rate of the synthetic fiber of above-mentioned porous hollow form three-dimensional crimp still is subjected to certain restriction, and circular hole is monolayer alignment, the pressurized easy deformation.
Up to now, still not having synthetic fiber and spinning thereof practical, the hollow form three-dimensional crimp more than nine holes comes out with spinnerets.Self-evident, what of the hollow porous number of fiber are very big to influence such as the degree of hollowness of fiber and fabric thereof, fluffy performance, rebound performance, thermal property.And for the requirement to fluffy performance with more excellent fiber and fabric thereof, rebound performance, thermal property, hydrophobicity, feel, proportion, health, people require further to develop nine holes synthetic fiber and spinning spinnerets thereof above, the three-dimensional crimp of porous hollow form.Fields such as sewage disposal in addition,, desalinization, gas filtration, pharmacy also require nine holes synthetic fiber and spinning spinnerets thereof above, the three-dimensional crimp of porous hollow form.Simultaneously, increasing of fiber hollow hole count also causes it to make difficulty further.On the other hand, the hollow hole count of fiber has inseparable getting in touch with fiber number, three-dimensional crimp degree and the product requirement of fiber.Have again, also must consider the processing characteristics and the price/performance ratio thereof of product.
The purpose of this utility model is: a kind of 16 hollow 3-D crimped fiber or staple fibres are provided, described fiber has best joint between the hollow hole count of fiber and fibre number, three-dimensional crimp degree and product requirement, and have excellent fluffy performance, rebound performance, thermal property, hydrophobicity, and has the processing characteristics and the price/performance ratio thereof of excellent product.The synthetic fiber or the staple fibre of 16 hole hollow form three-dimensional crimps of the present utility model are particularly useful for fields such as gas filtration, pharmacy.
Summary of the invention
16 hollow 3-D crimped fibers of the present utility model are characterised in that it is poroid that the cross section of described fiber is 16 hollows.
For obtaining the particularly product advantage of degree of hollowness height, fluffy excellent performance etc., be preferably, the cross section of 16 hollow 3-D crimped fibers of the present utility model is that two holes, center, its peripheral 12 emptying apertures are made isometrical annular distribution.
It is circular that emptying aperture cross section in the 16 hollow 3-D crimped fibers of the present utility model is generally, and also can form other special-shaped shape, for example, and oblateness, polygon etc.
