Description
Technical field
The present invention relates to the manufacture technology field of drafting, particularly relate to a kind of manufacture craft of special-shaped half elastic force drafting, relate to the manufacture craft that a kind of terylene has light abnormity half elastic force drafting in particular.
Background technology
Ultra-coarse denier lustrous terylene drawn yarn adopt by p-phthalic acid's (be called for short PTA), ethylene glycol (abbreviated as MEG) be polymerized make have light directly to spin melt to be raw material, to be made by the operation such as spinning, stretching.In current chemical fibre industry, the line density of polyester drawn yarns the most only can reach for 300 dawn, its production technology is: with PTA, what MEG polymerization was made has light directly to spin melt is raw material, after booster pump supercharging, spinning manifold is sent into by melt Conveying pipeline, and through measuring pump accurate measurement, melt shape fiber is formed after the filament spinning component in spinning manifold filters, as-spun fibre is become again through lateral blowing cooling curing, again after oil tanker oils, again through the first draw-off godet hot-rolling, second spinning reel hot-rolling carries out stretching HEAT SETTING, then by thread guide polyster fibre line is merged into and has light polyester drawn yarns about 300 dawn, finally will there is light polyester drawn yarns package build by winding head.The shortcoming of above-mentioned preparation method is: in production technology, the later stage of three leaf odd-shaped cross section lustrous fibre lines merges, and makes to lack cohesive force between monofilament, easily diverges in the use procedure of rear road; Monofilament cohesive force is uneven, and during stretching, between monofilament, tension force differs, three leaf abnormity have light easily to produce boundling is irregular, single wire fracture forms lousiness, thus after impact, road is weaved and the flatness of cloth cover, cannot reach the aft-loaded airfoil requirement of coarse denier fiber; And the polyester drawn yarns that conventional spinning obtains the most only can reach for 300 dawn, and range of application is restricted.
Nearest Two decades years comes, for improving polyester fiber moisture absorption, water vapour permeability, do a lot of work in Japan and Taiwan, according to patent report in the past, occurred two research peak periods, first research peak period is-1986 years nineteen eighty-twos, mainly with polymerization methods synthetic copolyester during this, then direct copolyesters carries out spinning, or by copolyesters and conventional polyester mixing after carry out spinning again; Second research peak period is nineteen ninety-five, mainly to synthesize batching or to add hole plasticizer in mixing mode, then via alkali treatment processing, makes fiber produce hole.
As Japanese Di Ren company released hollow micro-porous fibre first generation product patent in 1986, its commodity are called WellkeyFilament, its preparation is the microphase-separated principle utilizing conventional polyester and hole plasticizer, then after making high oriented yarn HOY (Highlyorientedyarn) via high-speed spinning, then give suitable alkali treatment and be prepared from.Japanese Di Ren company also utilizes unique chemical method simultaneously, by a kind of silk-fibroin of high-absorbency material, be coated on hygroscopicity fibre, develop " moisture-absorbing fibre ", this kind of fiber called after WellkeyMA fiber, the absorbing sweat/fast dry characteristic of its fabric, than strong ten times, conventional polyester fabric, but its hollow rate is not high, between 5-10%.In addition, the nineties in 20th century is developed the dry and comfortable fiber of the many micropores of hollow, trade (brand) name Hydropre at the Industrial Technology Research Institute of Taiwan's chemical industry place, and it adopts special spinning process, allows the inside and outside tube wall of fiber all have elongated groove, by these grooves and hole moisture absorption, moisture-inhibiting.But polyester fiber only has moisture absorption, moisture permeable effect is far from being enough.Above-described all patents only improve emphatically the moisture absorption of polyester fiber, ventilative, comfort type, do not improve other functions of fiber further.Certainly, the many microporous fibres of hollow are owing to preparing burden or pore former owing to having copolyesters or synthesizing, and spinning technique difficulty controls, and finished silk intensity reduces, takes easy fibrillation in process, functional after-finishing not easily carries out, and before fibroblast, give functional form also certainly will be more difficult.
Along with the raising of people's living standard, various comfortableness, health functional fibre emerge in an endless stream.So can produce and both there is moisture absorption, moisture permeable effect, there is there again the fiber of manifest function health properties? first, because the many microporous fibres of hollow are inherently wayward by hollow type spinnerets spinning technique by two kinds of component slices, moreover after adding function modified master batch, require stricter to spinning and aftertreatment technology.At present, there is no the report of this respect both at home and abroad.
Terylene as one of the large main force of three in synthetic fiber fiber, because its excellent physics and chemistry characteristic is widely used in garment material and other non-garment industry.Dacron product since appearance, also once so that its drapability is good, intensity is high, well-pressed and be used as main textile raw material to weave all kinds of textiles by downstream user.Along with economic globalization, internationalizationof of market, the requirement of people to clothes is also more and more higher, not only comfortableness will be had, also will have functional, fabric is just to light, soft, functional future development, and composite fibre materials just needs to improve constantly performance to meet requirements of weaving process.
Nearly ten years, the development of China polyester industrial rapidly, polyester fiber output from 516.5 at the beginning of 2000 ten thousand tons develop into ten thousand tons, 2700 at the end of 2010, average annual growth rate, more than 25%, has accounted for 66% of global polyester output.Terylene has become the maximum synthetic fiber kind of output in chemical fibre, is widely used in clothing, decoration, household textiles, fabrics for industrial use and the national economy such as national defence, Industrial Engineering various aspects.5 years from now on, also will keep increasing fast.But as textile material, polyester fiber also has obvious shortcoming.Therefore, the processing method of science, efficient, high-quality, energy-saving and environmental protection is selected, to adapting to and promoting that the high speed sustainable development of polyester industrial, polyster fibre is most important.
Although in synthetic fiber, polyester fiber has the multiple performance of applicable textile applications and industry application, and thus it has achieved the development attracted people's attention since large-scale production.But along with the progress of World Science technology and the development of world industry, polyester fiber is in performance and the requirement that functionally can not meet people completely.The result of development and innovation makes to be developed large quantities of differential, functionalization and high performance synthetic fiber.
Due to " small-size effect ", " interfacial effect ", " quantum size effect " and " macro quanta tunnel effect " that nano material has, nano material is made to show the specificity different from common material in structure, photoelectricity, magnetic and chemical property etc.
Full-drawn yarn adopts low speed spinning, high-speed stretch technique, and two procedures is on a spin-drawing combination machine, for one-step technology route, spinning speed is 900-1500m/min, stretching and winding speed is 3200-4200m/min, draw ratio is about 3.5, and full-drawn yarn has the more stable feature of quality.
Present inventor is devoted to material modification to have in light abnormity half elastic force drafting at terylene to transform, and subsequent treatment carries out particular design, and completes the present invention in conjunction with full-drawn yarn production technology of the prior art.
