The method comprises that A and B materials are subjected to melt extrusion through respective screws to enter a spinning case through respective melt filters, wherein the spinning case comprises two case bodies; the A materials enter the main case body, the B materials enter the auxiliary case body, and the A and B materials are distributed and metered in the spinning case, and melts formed by the A and B materials flow into a spinning component simultaneously to be sprayed out by a spinneret plate to form spinning melt trickles which are drafted and shaped after being cooled and solidified to form hollow fibers; hollow fiber tube walls are formed by the A and B materials along the fiber axial directions, and the tube wall sections are formed by C-shaped sections and C-shaped section notch sections, wherein the C-shaped sections are formed by the A materials, the notch sections are formed by the B materials to fill the notches of the C-shaped sections, and the B materials are soluble component. By means of the fibers, moisture is covered by the C-shaped cavity directly, the fiber tube walls have micro holes and micro pits, and accordingly, the fiber water-absorbing capacity is improved, the fiber flexibility is improved, and the fibers feel like cotton.
Description
Technical field
The present invention relates to the production method that water conservation imitates cotton fiber, it belongs to production of chemical fibre technical field.
Background technology
The production method of current high water-absorption fiber is mainly through two kinds of approach, and one produces fibers with profiled section, improved the moisture content of fiber by the contact area improving fiber and water.Another kind produces with the doughnut of micropore, and its tube wall has micropore, by siphonage in moisture content inspiration pipe, but when tube wall is done thicker a little time, molten not thoroughly, micropore amount greatly reduces, and moisture just cannot permeate into.The fiber of profiled filament to be cross section for circular fiber be certain geometrical shape.Profiled filament is compared with general fiber, and surface area is large, can strengthen covering power, reduces the transparency of fabric.The deficiency of the easy balling-up of annulus fiber can also be improved.Because cross section is special shape, the cohesive force between energy fortifying fibre, improve bulkiness and the gas permeability of fiber, the anti-performance of reeling off raw silk from cocoons of its fabric is better than circular fiber.The fibers such as prior art mainly production hollow tangerine lobe fiber, H type or rice font, rely on fiber shape to carry out adsorption moisture, its principle is that moisture abutment surface tension force is adsorbed on fiber, to improve water absorption rate, but effect is not very desirable, the fibrous absorbent rate that prior art is produced is no more than 10%.
Summary of the invention
In view of the defect that existing production method exists, the invention provides the production method that a kind of water conservation imitates cotton fiber, the method produces the doughnut by A, B two kinds of material compounds, directly wraps up moisture, substantially increase the water absorption rate of fiber by C cavity; Fiber tube wall has micropore and Wei Keng, improves the indexs such as the pliability of fiber, and the circular cross-section rigidity of C type section ratio ordinary hollow fiber diminishes simultaneously, and about decline 40%, also improve the pliability of fiber, feel is very good.
For achieving the above object, the technical solution adopted in the present invention is the production method that a kind of water conservation imitates cotton fiber, by A, respective feed bin is put in the section of B two kinds of materials, melt extrude through respective screw extruder, again after respective fondant filter filters, spinning manifold is entered by melt pipe, spinning manifold adopts two casing, for main box and auxiliary box body, A material enters main box, B material enters auxiliary box body, A, B two kinds of materials distribute in respective spinning manifold, metering, the melt tributary that the some flows of each self-forming are completely equal, A, the melt tributary that B two kinds of materials are formed enters filament spinning component simultaneously, spray through spinnerets, axis along flowing is formed by A, the spinning melt thread of the hollow that B two kinds of materials are formed, nascent doughnut is become through cooled and solidified, nascent doughnut passes through drawing-off, sizing forms doughnut, doughnut tube wall is formed along fiber axis to by A material and B material, tube wall section is made up of the indentations section in C type cross section and C type cross section, C type cross section is made up of A material, indentations section is made up of B material, fill the breach in C type cross section, B material is soluble component.The section of described A, B two kinds of materials is carried out pre-crystallized, dry before spinning.Described spinning melt thread is by lateral blowing or ring quenching.Described doughnut is spun into long filament or short silk, forms the hollow long fiber or the hollow core staple fibers that meet length requirement.B material dissolution in described doughnut, is formed and is made up of A material, and tube wall section is C type cross section, has the fiber of cavity structure.Described A material is be made up of the multicomponent containing non-solubility component and soluble component, and soluble component content is greater than 0% and is less than 50%; Soluble component in A material in described doughnut is dissolved, forms loose structure on the inside and outside surface of the tube wall of doughnut.The hole of loose structure is micropore on tube wall surface or micro-hole.Hole on inner surface and the hole on outer surface are formed through through hole.Described doughnut tube wall section is circular rings, vesica piscis or closed arc ring.Described A material is PET, and described soluble component is COPET.
After adopting said method, have following beneficial effect: water conservation imitates the production method of cotton fiber compared with art methods, the as-spun fibre produced forms notched doughnut after being dissolved by subsequent handling, and its section is C type cross section.This fiber is that moisture content directly enters C cavity by breach, namely directly with C cavity parcel moisture content, so just substantially increases the water absorption rate of fiber.Simultaneously because cross section is C type, also substantially improve the indexs such as the pliability of fiber.In addition, fiber tube wall can change into the tube wall with micropore and micro-hole as required, change the fineness of fiber surface, also moisture can be absorbed by siphonage, this special water conservation fiber has good moisture absorption hydrofuge function, improve fiber flexibility simultaneously, make fabric hand and function more as cotton.This kind of mode not only greatly can improve the moisture content of fiber but also is convenient to the control of moisture content, uses flexibly.
