Description
Technical field
The present invention relates to a kind of manufacture method of bright straight polyester filament, a kind of manufacture method of carrying out the bright straight polyester filament of lateral blowing cooling with certain angle particularly is provided.
Background technology
Along with the raising of socio-economic development level and living standards of the people, people to wearing comfortableness, have had higher requirement to lining, style and the style of dress ornament.The traditional fibre cross section is circular, the gloomy no obvious gloss of fabric, and profiled filament is because of the variation of its section morphology, it is compared with general chemical fibre have unique character, mainly be presented as the following aspects: the different geometric cross sections of fiber can make light produce refraction and beam split as prism, and then reflect colorful light, and make fiber produce a kind of gloss of superbright; Gap between fiber and yarn is many, has air permeability and good than the common textiles of same specification; Fiber surface area is big, and absorption property is good, can be used as material for air purification; The cohesive force of fiber is strong, and fluffing and pilling effect can significantly reduce, and also can improve drapability and wrinkle resistance etc., and profiled filament has above-mentioned many excellent properties, more and more is subjected to the favor in market.
" one " shape fiber, claim flat fiber again, it is as a kind of novel profiled filament, has level and smooth fine and smooth feel, good piloerection, flash of light gloss, in toy suede and Fake Furs field just in extensive use, the basic at present all dependence of high degree of profile " " shape fiber import, supply falls short of demand for product, and just in rising trend.Common " one " shape fiber is under the high-speed production condition, cause inhomogeneous cooling easily, the crystallization imperfection, the yarn evenness lack of homogeneity, dyeing back tow gloss dimness, tow fluffing easy to wear, degree of profile is generally lower, generally between 60%～80%, can't satisfy people to fabric high glaze, high brightness, high chromatic quality requirement.
Document " terylene has reason and the countermeasure that lousiness forms in the flat FDY production of light " (synthetic fiber: 4,35～37,2005) finished product flatness mentioned in is lower, has only reached 7.0, and being converted into degree of profile with formula degree of profile=(1-1/ flatness) * 100% is 85.7%; Spinning jet used micropore is a rectangle, melt-flow is uneven through the normal stress of hole wall, the extrusion swelling that causes melt also is uneven, the fiber degree of profile is reduced greatly, thereby make fiber in spinning and drawing process, produce a large amount of lousiness and broken end, the glossiness of fiber reduces, and this has also brought the bigger challenge on the process maintenance for the smooth production of fiber; The spinnerets micropore major axis that document adopted points to the plate heart, and circular array, the blowing mode is blown for ring, blowing direction is parallel to the long axis direction of spray silk micropore, and wind is from evacuating between tow, is not very big and generally require air quantity when spinning flat filament, this will seriously cause cooling effectiveness to reduce, the suffered cooling condition inequality in flat filament two ends makes fiber produce curved surface simultaneously, causes degree of profile, glossiness and the bar of fiber to do all reductions greatly of uniformity.
Document " has light flat polyester staple fiber spinning technology " (polyester industrial: 17 (3), 23～25,2004) the spinnerets micropore that is adopted also is rectangle, and spinnerets micropore major axis points to the plate heart, and circular array, the same but mode of ring blast-cold that adopts, blowing direction is parallel to the long axis direction of spray silk micropore, and this causes cooling effectiveness to reduce, simultaneously the suffered cooling condition inequality in flat filament two ends, make fiber produce curved surface, the degree of profile of fiber, glossiness and bar are done uniformity and are all reduced greatly.The zone of silence length that document adopts is 75mm～100mm, and the finished product flatness is also lower under this condition, only reaches 7.9, and being scaled degree of profile is 87.3%.The zone of silence length of tradition spinning filament is about 80mm, though satisfy the technological requirement of general polyester filament, but for profiled filament, especially bright straight polyester filament is shaped, melt flows in special-shaped duct and is difficult for stablizing on the one hand, increase fiber surface tension force and fracture possibility on the other hand after the heteromorphosis again greatly, increased the fine difficulty of one-tenth, must cause spinnability to descend.If air outlet is too near from spinning plate surface, owing to rapid cooling may produce skin-core structure, broken end or lousiness appear in fiber easily in drawing process, while dyeing uniformity variation, so under the prerequisite of assurance degree of profile, suitable increase zone of silence length.
Because the good characteristics such as high degree of profile, high-luster and dyeing uniformity that bright straight polyester filament requires, make it be different from conventional polyester spinning in process of production, and since prior aries such as the design of spinnerets micropore, process for cooling that is that all right is ripe, make unstable product quality, fiber produces curved surface, and cross sectional shape is irregular, degree of profile reduces (as shown in Figure 1), back processing end breakage rate height, stiff silk, lousiness are many, and it is poor to dye.By the available data analysis, being not difficult to find out to produce has the flat polyester fiber the deficiencies in the prior art of light.
Summary of the invention
The manufacture method that the purpose of this invention is to provide a kind of bright straight polyester filament particularly provides a kind of manufacture method of carrying out the bright straight polyester filament of lateral blowing cooling with certain angle.The invention solves bright straight polyester filament cross section glacing flatness difference and the low problem of degree of profile that prior art is produced, remedied the deficiency of the bright straight polyester filament gloss dimness that prior art makes, tow fluffing easy to wear and dyeing difference.
The manufacture method of a kind of bright straight polyester filament of the present invention, adopt the fusion of big glossy polyester melt directly to spin mode, its preparation technology's flow process is big glossy polyester melt, and---------------------oil tanker oils---twice drawing-off---reels filament spinning component measuring pump spinning manifold the melt Conveying pipeline booster pump in the lateral blowing cooling, obtain bright straight polyester filament, it is characterized in that: the lateral blowing direction has an angle theta with " one " shape spray silk micropore long axis direction, adopt and relax methods for cooling, spinnerets filament mouth zone of silence length is 130mm～140mm, and spray silk micropore cross sectional shape is the geometry that the camber line of inside contraction of two circular arcs of connection of two the symmetrical circular arcs in end and two symmetries combines.
