Abstract
The invention relates to a hollow heat insulation fiber being warm in winter and cool in summer. The hollow heat insulation fiber comprises polyester filament yarns with specifications of 1.0-3.0 dtex and polyester staples and belongs to the field of textile materials. The preparation process comprises the following steps of: obtaining hydrophilic modified polyester masterbatch through chemical modification; adding calcium carbonate powder to a polyester slice to obtain the calcium carbonate powder polyester masterbatch; blending, melting and spinning the polyester, the hydrophilic modified polyester masterbatch and the calcium carbonate powder polyester masterbatch according to a certain proportion; extruding the mixture by a C-shaped or circular arc spinneret plate; and obtaining hydrophilic hollow polyester filament yarns and polyester staples. In the follow-up dyeing process, the calcium carbonate component is removed and a large amount of micropores and ditches are formed on the surface of the fiber so that the fabric has the characteristics of moisture absorption, air permeability, dryness, heat insulation and the like; and the hollow heat insulation fiber is widely applied in the fields like thermal underwear, casual dresses, outdoor exercises and the like.
Description
Technical field
The present invention relates to the heat insulation fiber of a kind of hollow, particularly a kind of heat insulation fiber preparation method of many micropores hollow with water-wet behavior.
Background technology
Doughnut is a kind of important profiled filament that cross section has cavity vertically; Its hollow structure has not only reduced the weight of fiber 20～30%; And comprised a large amount of still airs, and make fabric in light, thermal property improves 60～80% than common homogeneity lining.China is the progression growth to the market demand of doughnut, and domestic each manufacturer continually develops new varieties, and the researchs such as production technology, structure and performance about doughnut simultaneously also emerge in an endless stream.The production of doughnut mainly is to adopt profile spinnerets such as annular hollow, C type, eccentric hollow to make through melt spinning.
High doughnut of thin dawn, the mesopore fiber of the Korea S's Huvis that exists in the market; Circle four holes of E.I.Du Pont Company, circular seven apertures in the human head fiber; PET Hollow stereo crimped fiber, the four hole 3-D crimped fibers of levying the appearance chemical fibre all are the structures through single hole or porous; Improve the degree of hollowness of fiber, come the thermal property of fortifying fibre.But, utilize the prepared fabric of this kind fiber, though have excellent effect of heat insulation; But, can feel clammy in winter because the hydrophobic property of polyester itself can not effectively absorb, derive sweat and moisture; Can feel very damp and hot in summer, clothing wears very uncomfortable.There is the doughnut of micropore on the surface that Dong Li company produces, and with the fiber surface microporeization, roughening improves fiber specific surface area and porosity through the single one physical modification, in the hope of obtaining moisture absorption, warming effect.Than other doughnut, this method improves the hygroscopicity of fabric ability to a certain extent only through improving fiber specific surface area, does not change the hydrophobic characteristic of fiber.Even fabric is carried out hydrophilic finiss, finishing agent also can cause the fiber porosity to reduce greatly micropore landfill, the obstruction of fiber surface.
The present invention introduces hydrophilic radical and calcium carbonate powder component in spinning process; Make hydrophobic synthetic fiber change hydrophilic polyester fiber into, give the fiber multi-cellular structure simultaneously, initiatively adsorb sweat and moisture; And the hollow structure through fiber is derived with many micropores on surface, the capillary wicking passage that groove forms fast; And then to external loss, keep the dry and comfortable, comfortable of body surface, not moist unhappy clammy, the damp and hot sense of multiple common doughnut; And the hollow of fiber and multi-cellular structure; Include a large amount of static air; Make fiber have good insulative properties; The heat that can effectively completely cut off on the health in winter makes it not to external diffusion, can the heat in the environment is isolated outside in summer, and prepared fabric has real effect cool in summer and warm in winter.
Summary of the invention
The present invention aims to provide a kind of many micropores of hydrophily hollow polyester fiber with effect cool in summer and warm in winter.
Technical scheme of the present invention reaches in the following manner:
With polyester (component A), (5～20) % hydrophilic modifying polyester master particle (B component) and (2～30) the % calcium carbonate powder polyester master particle (component C) of (50～93) %, behind three kinds of raw material chip dryings, blend by weight percentage; The input screw extruder; Measuring pump metering back input spinning manifold (290 ℃ of spinning temperatures), after " C " type or circular arc spinnerets were extruded, blowing was cooled off and is oiled; Behind the integrated tow, make long filament or short fiber through following technology:
1) tow is reeled (speed 4000m/min) through drawing-off (90 ℃ of drawing temperatures lead 3 times of body multiples), typing (120 ℃ of temperature), makes the FDY long filament.
2) tow makes POY through reel (speed 2500m/min), and drawing-off adds bullet (160 ℃ of drawing temperatures, 2 times of drafting multiples), makes the DTY long filament;
3) tow reel (speed 1400m/min), behind the boundling through the two-stage drawing-off; One-level drawing-off (88 ℃ of drawing temperatures, 3.5 times of drafting multiples), secondary drawing-off (100 ℃ of drawing temperatures, 1.1 times of drafting multiples), relaxation heat setting (125 ℃ of temperature; 60min), cut off the back packing and make staple fibre.
The fiber that adopts above-mentioned technology to obtain, in follow-up dye process, calcium carbonate components wherein can be in the environment of acidity natural decomposition, can form the fiber surface multi-cellular structure.
The heat insulation fiber of many micropores of the prepared hydrophily of the present invention hollow has effect cool in summer and warm in winter; Its beneficial effect is embodied in: the hydrophobic property of 1) considering terylene itself; In polyester slice, introduce the hydrophilic modifying component; Thereby form a large amount of hydrophilic radicals at fiber surface, have the initiatively moist effect of absorption; The calcium carbonate components of 2) adding in the required sour environment of follow-up dyeing terylene technology, disappears through chemical reaction; Form many micropores and groove in PET fiber surface, these micropores and groove even can run through whole fiber, UNICOM's fiber surface and inner chamber; Make the hollow structure of fiber itself form the wicking passage; Derive sweat and moisture rapidly through wicking, keep the dry and comfortable comfortable of skin, solved clammy, the damp and hot defective of common doughnut; 3) hollow structure of fiber, a large amount of static air that comprises make fiber have heat insulation characteristic, and the many micropores and the groove of fiber surface gives fiber higher degree of hollowness, and effect of heat insulation is more outstanding.
