Detailed description of the invention
Referring more particularly to accompanying drawing, Fig. 1 show a kind of high surface ultimate fibre constructed according to the invention, hereinafter referred to as fiber 10. Fiber 10 can be formed as continuous length and the diameter with any appropriate as required. Fiber 10 includes continuous print internal fiber 11, and it is central shaft 12 longitudinal extension longitudinally. Internal fiber 11 has multiple lower limb 14, and described lower limb is with parallel relation and extension longitudinally parallel with central shaft 12 between generally mutually. Each in lower limb 14 extends radially outwardly the central body 16 away from internal fiber 11 in the way of branch, and thus away from central shaft 12 to first peak 18. When lower limb 14 extends with the relation being parallel to each other, multiple continuous print first passages 20 are formed by lower limb 14, and wherein each in passage 20 is formed as continuous print recess between adjacent lower limb 14. Therefore, first passage 20 with parallel relation between generally mutually and also extends parallel to central shaft 12. At least some in lower limb 14, shown here for each in lower limb 14, there is elongated spine (ridge), also referred to as salient angle (lobe), spine, finger piece, protuberance or arm 22, extend laterally outward out from lower limb 14. Each in arm 22 extends radially outwardly to the second peak 24. Arm 22 is with parallel relation between generally mutually and is longitudinally extended continuously abreast with central shaft 12, and therefore forms continuous print second channel 26 between adjacent arm 22. The lower limb 14 of the longitudinal extension of internal fiber 11 and arm 22 provide the surface area increased compared to cylindrical monofilament for internal fiber 11, this so that when improving when woven (woven), knitting (knit), braiding (braided) or otherwise form fabric fiber 10 filter and absorb the ability of sound and/or fluid. Therefore, adopt the fabric that fiber 10 is formed, no matter fiber 10 is interleaved by woven, knitting or braiding, also referred to as interwoven yarns or intertexture ultimate fibre, no matter or formation of fabrics is non-woven material, all there is the net being formed as including little fiber 10 at least partly, can both filter with the ability increased and/or absorb microgranule, sound and fluid.
Fiber 10 is initially formed as double-component co-extrudate, its internal fiber 11 adopts first material with the above geometric properties to extrude with overlapping with central shaft 12, and its external jacket 28 adopts the second material to extrude around the first material simultaneously, hereinafter referred to as common extrusion. External jacket 28 can fully enclosed or partial encapsulation internal fiber 11, to be filled up completely with or to fill at least partly the first and second passages 20,26, wherein the first and second materials are different types of material. First material can adopt standard thermoplastic's resin material to extrude, for instance polypropylene, polyester, nylon, polyethylene, thermoplastic polyurethane, copolyesters or liquid crystal polymer, these are only that example does not have restriction effect.Second material adopts the soluble resin thermoplastic extrusion sacrificed, for instance but it is not limited to polylactic acid (PLA), copolyester (PETG), polyvinyl alcohol (PVA), ethenol copolymer (EVOH) or water solublity thermoplastic polymeric resin. Therefore, by extruding bicomponent fibers 10 and making extrusion fiber 10 solidify, external jacket 28 can easily dissolve when needed, including just after extrusion solidification, or after forming required final products (such as textile material, whether woven, knitting, braiding or nonwoven). Therefore, first can being processed as the ultimate fibre of usual standard by fiber 10, fiber 10 has generally circular cross section, or includes generally elliptical or flat cross section, then after the final product is formed, external jacket 28 solubilized exposes the internal fiber 11 of encapsulation. Therefore, internal fiber 11 is processed into fabric and can become easy, as standard ultimate fibre, afterwards, by dissolving external jacket 28 from internal fiber 11, it is possible to expose the shape that internal fiber 11 is more complicated. In order to dissolve external jacket 28, the solvent of any appropriate can be used, depend on the material composition of the second material, use such as NaOH, acid, or when water-soluble polymer such as Exceval, water dissolution external jacket 28 can be adopted.
As shown in Figure 6, in order to improve manufacture efficiency, multiple fibers 10 jointly can be extruded in single sacrifice external jacket 28, and therefore, by dissolving external jacket 28, multiple independent fibers 10 just come out for being used alone.
The central body 16 of internal fiber 11 may be formed to have the cross-sectional geometry of arbitrarily needs, including circular, oval or other. Lower limb 14 extends radially outwardly along the whole length of central body 16 from central body 16, and has relative side, hereinafter referred to as the first side 30. The first relative side 30 of each lower limb 14 is shunk towards first peak 18. Each in the first relative side 30 has at least one arm 22, it is shown that for multiple arms 22, arm 22 extends laterally outward from the first side 30. Each arm 22 extends from its position extended out along the whole length of lower limb 14, and each arm 22 has relative side, hereinafter referred to as the second side 32, shrinks towards the second peak 24. Therefore, not having from its arm extended outward compared to lower limb, the surface area of each lower limb 14 increases due to the extra surface area that provides from the side 32 of its outward extending each arm 22. Will be appreciated that, lower limb 14 and arm 22 can be configured to the shape and profile with arbitrarily needs, such as shown in Fig. 2 A, 2B, wherein lower limb 14 is generally bending or "the" shape shape, form due to the outward extending bending of arm 22, and as shown in Fig. 3 A, 3B, the shape that wherein lower limb 14 is generally triangular, and arm 22 generally mutually between for mirror image relationship ground stretch out from relative side 30. It is also recognized that, lower limb 14, arm 22 and the quantity of the first and second passages 20,26 being associated can provide as required, and further, lower limb 14, arm 22 and the width of the first and second passages 20,26 being associated and highly for the size of Nano grade, such as, about between 200-1000 nanometer, depending on that it is applied.
Many amendments or what modification was all possible to according to teachings above. It is understood, therefore, that except the above, the present invention can also embodied in other, the scope of the present invention is limited by the claims finally permitted.
