Abstract
The utility model relates to a hexaphyllous hollow fiber and a spinneret plate thereof, wherein the cross section of the fiber is hexaphyllous, and a hollow cavity is arranged inside the fiber; the hollow cavity is circular; the outer contour of the cross section of the fiber is composed of a circle, six bulges which are hexaphyllous are arranged outside the circle; the filament number is equal to 0.8-3.0dtex; the hollowness is equal to 15-22%; and spinneret micropores in the spinneret plate are uniformly distributed in a single spinneret plate and composed of three sections of circular arc narrow slits with the same length and two gaps on each section of circular arc. The hexaphyllous hollow fiber has the advantages that the luster effect of the fiber can be improved through the change of the hexaphyllous hollow section; the waxy sensation of a common fiber textile is improved through the change of the shape of the section; due to the change of the shape of the section, the cohesive force among fibers is increased, and the pilling resistance of the textile is also improved; and the hexaphyllous hollow fiber has excellent bulkiness property and high fiber void ratio, so that the water absorbing and discharging properties of a fibermesh are improved.
Description
[technical field]
The utility model relates to the functional fibre technical field, specifically, is a kind of sexfoil doughnut and spinnerets thereof.
[background technology]
Along with the progress of society and the raising of living standards of the people, more and more higher to the comfort property requirement of fibrous material dress to clothing fabric, style and style, this has also promoted the exploitation of New Products from Man-made Fibres, satisfies people's demand.Because the characteristic of the cross sectional shape of fiber and fiber is closely related, can obtain the needed various characteristics of people by means of the change of fibre section shape.
Cross sectional shape and structure that common synthetic fiber face is rounded, solid, lack good suction, moisture pick-up properties, regain only is 0.4%, about fracture strength 5.0cN/dtex, extension at break 20-30%, initial modulus reaches 110cN/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.
Make the emulation mode that Profiled hollow fiber improves the synthetic fiber performance, be extensive use, effective one of modified method.Can give the various performance advantages such as fabric sheen, bulkiness, hygroscopicity, elasticity and feel after the abnormity modification, so foreign fiber is widely used, the section of the profiled filament that has now occurred has triangle, trilobal, pentagon, T shape, C shape, H shape, cross, pancake and the hollow opposite sex.
The change of cross sectional shape can improve the gloss effect of fiber, and the profiled filament of hollow shape, because there is again internal reflection simultaneously in its corresponding attenuate in reflecting layer, superficial reflex and internal reflection comprehensive can be strengthened catoptrical intensity, and gloss effect is better.The change of cross sectional shape is so that the coefficient of friction of fiber also can change, and fiber is quiet, the difference phase strain of the coefficient of kinetic friction is large, has improved the wax-like sense of general fibre fabric; The change of cross sectional shape also so that interfibrous cohesive force increases, has improved the anti-fluffing and anti-pilling performance of fabric; The introducing of hollow structure not only can reduce the quality of fiber, and increased the fiber gap rate, thermal property and the bulkiness of fiber under heavy load of fabric have so just been improved, so that fiber under high load capacity, still can keep its original shape, simultaneously under mutual entanglement effect between fibrous lofted, suppressed fiber web becomes felt after long-time use the phenomenon, also just because of the bulk performance of its excellence, the fiber gap rate is large, thereby has improved fibroreticulate suction, performance discharges water.
[utility model content]
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of sexfoil doughnut and spinnerets thereof are provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of sexfoil doughnut is characterized in that, the cross-sectional profile of described fiber is sexfoil and inside is cavity;
Described cavity is circular;
The outline of the cross section of described fiber is made of circle, and circular outer has six projections, is sexfoil;
The filament number of described sexfoil doughnut is 0.8～3.0dtex.
The degree of hollowness of described sexfoil doughnut is 15～22%.
The utility model also provides a kind of sexfoil doughnut spinnerets, the spinneret orifice of described spinnerets (as shown in Figure 2) is by the even distribution that is arranged as on the monolithic spinnerets, and spinneret orifice is made of two slits on isometric three sections circular arc narrow slits and the every section circular arc; Its hollow spinneret plate internal diameter 0.28mm, the spacing of narrow slit abutting end is 0.06～0.15mm between external diameter 0.34mm, three sections circular arcs, and sexfoil length is 0.24mm, and sexfoil thickness is 0.06mm.
Compared with prior art, good effect of the present utility model is:
The utility model has the advantages that the change of the sexfoil hollow sectional shape of fiber can improve the gloss effect of fiber.The simultaneously change of cross sectional shape has improved the wax-like sense of general fibre fabric; The change of cross sectional shape also so that interfibrous cohesive force increases, has improved the anti-fluffing and anti-pilling performance of fabric; The introducing of hollow structure has improved thermal property and the bulkiness of fiber under heavy load of fabric, so that fiber is under high load capacity, still can keep its original shape, simultaneously under mutual entanglement effect between fibrous lofted, suppressed fiber web becomes felt after long-time use the phenomenon, also just because of the bulk performance of its excellence, the fiber gap rate is large, thereby has improved fibroreticulate suction, performance discharges water.

Fig. 1 is the schematic cross-section of a kind of sexfoil doughnut of the present utility model;
Fig. 2 is a kind of sexfoil doughnut of the present utility model spinnerets micropore schematic diagram.
[specific embodiment]
The specific embodiment of a kind of sexfoil doughnut of the utility model and spinnerets thereof below is provided.
Embodiment 1
A kind of sexfoil doughnut as shown in Figure 1, the outline in described sexfoil doughnut cross section mainly is made of circle, circular outer has six projections, is sexfoil.The filament number of described sexfoil doughnut is 0.8-3.0dtex.Degree of hollowness is 15-22%.
The utility model also provides a kind of sexfoil doughnut spinnerets, the spinneret orifice of described spinnerets as shown in Figure 2, the spinnerets micropore is made of two slits on isometric three sections circular arc narrow slits and the every section circular arc.Its hollow spinneret plate internal diameter 0.28mm, the spacing of narrow slit abutting end is 0.06-0.15mm between external diameter 0.34mm, three sections circular arcs, and sexfoil length is 0.24mm, and sexfoil thickness is 0.06mm.
Through evidence, a kind of sexfoil doughnut of the present utility model and spinnerets have improved common synthetic fiber dry-touch wet permeability performance really, and gloss effect is better, are not easy to be stain after making fabric; So that fabric has fluffy sense, good hand touch has improved fabric breathability and pilling resistance simultaneously.
The above only is preferred embodiment of the present utility model; should be pointed out that for those skilled in the art, without departing from the concept of the premise utility; can also make some improvements and modifications, these improvements and modifications also should be considered as in the protection domain of the present utility model.
