Abstract
The invention, relating to a production technology of recycled bottle chip-spinning profile fiber, is characterized in that the production steps consist of bottle chip screening, bottle chip drying, high temperature melting, screw extruding, spinneret ejecting, cooling oiling, forming winding, balancing, drawing, deforming, networking and finishing. The spinneret hole of the spinneret adopted is formed by combining the cross-type holes with the arrangement mode representing concentric circle shape; the number of the cross-type holes equals to the number of profiled single fibers, thus allowing the cross section shape of the profile fiber ejected from the holes and formed by the post process to represent cross-type. The invention is widely applied.
Description
Technical field
The present invention relates to a kind of production method of profiled filament, specifically a kind of returnable bottle sheet spins the production method of " ten " word profiled filament.
Background technology
Utilize the returnable bottle sheet to spin the problem of environmental pollution that not only can solve polyester, realize resource circulation utilization, the protection environment; Also can reduce energy resource consumption, reduce the dependence of China to international crude oil, the most basic benefit is that the reclaimed materials cost is relatively low, and product price is with the obvious advantage, and the market space is huge.But the synthetic fiber that general returnable bottle sheet melt spinning is made, because its institutional framework form is more single, compare with natural fabric, no matter on structure or performance have and want when big gap, the fiber surface low in glossiness, exist easily dirty, shortcoming such as easily balling-up, water imbibition are poor, and bulkiness is poor, feel is poor, elasticity is little.Owing to returnable bottle sheet stock impurity content height, fusing point and viscosity differences are very big, bring a lot of destabilizing factors to melt production, the fiber lack of homogeneity simultaneously.
Summary of the invention
It is good that technical problem to be solved by this invention is to propose a kind of fiber surface glossiness, moisture absorbing and sweat releasing, bulkiness and feel all better and the stable returnable bottle sheet of production control spin the production method of " ten " word profiled filament.
To achieve these goals, the present invention can adopt following measure to realize: its production stage comprises a bottle sheet screening, bottle sheet drying, and high-temperature fusion, screw rod is extruded, the spinnerets ejection, cooling oils, and is shaped to reel, and balance stretches, distortion, network, finished product.
To achieve these goals, the present invention can adopt following measure to realize: the cross section of fiber of the present invention is abnormity, and the different form on the fibre section is " ten " font.
To achieve these goals, the present invention can adopt following measure to realize: the spinneret orifice of the spinnerets that is adopted is combined by the hole of " ten " font, makes the cross sectional shape of the profiled filament that is shaped through its ejection and through the postorder operation be " ten " font.
To achieve these goals, the present invention can adopt following measure to realize: the production special spinning jet that is used to produce above-mentioned profiled filament, its spinneret orifice is made up of a plurality of " ten " font hole, and its arrangement mode is concentric circles to be arranged, and the quantity in " ten " font hole is identical with profiled filament monofilament quantity.
To achieve these goals, the present invention can adopt following measure to realize: being used to produce its drying equipment of above-mentioned fiber is special bottle sheet drying tower.The reducing form is adopted on drying tower profile top, and inner tip has increased by 3 leg-of-mutton cones.
To achieve these goals, the present invention can adopt following measure to realize: being used to produce its fusant filtering equipment of above-mentioned fiber is 3 grades of vertical filters.
The present invention has adopted special drying and fusant filtering equipment, the reducing form is adopted on drying tower profile top, inner tip has increased by 3 leg-of-mutton cones, successful solution in the continuous bottle sheet dry run because its bottle chip architecture is little, put up a bridge in the tower that light specific gravity brings, bad phenomenon such as shortcut are walked in absorption, drying effect strengthens, and has guaranteed the normal stable operation of spinning.3 grades of melt filtration devices of Cai Yonging have effectively been removed the impurity of reclaimed materials bottle sheet too high levels simultaneously, improve filter quality, prolong the assembly life cycle, have guaranteed the normal operation of spinning, have promoted the quality of product.By above-mentioned production process equipment and production method, and the production special spinning jet of above-mentioned technical pattern, earlier fibrous raw material is at high temperature extruded from spinnerets during production, cooling curing then, drawn forms fiber.The melt that comes out from spinnerets " ten " font hole, according to expanded principle and melt rheology principle, the ejection back forms profiled filament from the hole, and the shape of " ten " font hole assembled arrangement is exactly the global shape of strand cross section.Because the present invention has imported the exploitation of textiles with natural capillary theory, fiber vertical produced many grooves, and fiber can absorb water fast by the wicking of these grooves, water delivery, and diffusion and volatilization, thus reach the function of moisture absorbing and sweat releasing.The cross-sectional area coverage rate of " ten " font fiber that the present invention produces is between 70-80%, under the identical situation of fiber quality (weight), the common profiled filament of surface area ratio increases 20-30%, thereby improved greatly fiber bulkiness, elasticity, make fiber that the feel of natural fabric be arranged, capillary effect and gas permeability are very high, and wicking capacity substantially exceeds common profiled filament textiles.The lining that the bottle sheet profiled filament of being produced by the present invention is made into, quality is slim and graceful, be through and give sliding suitable, ventilative, comfortable sensation on one's body, and fabric need not special processing, Machine Washable and oven dry are used very extensively, availablely are used to produce dress ornaments such as shirt, jacket, Training wear, underwear, be used in particular for Defence Force and make military clothes, to adapt to army's job requirements under some adverse circumstances.
Concrete enforcement
Spinning production method with the returnable bottle sheet of DTY75D/72F " ten " font kind is example, the concrete step of implementing has: adopting the bottle sheet that reclaims is rapidoprint, after screening, be delivered to the crystallizing bed crystallization (temperature is 275 ℃) of giving, crystallization bottle sheet completely falls into drying tower (265 ℃ of baking temperatures) by deadweight, bottle sheet moisture content is 25--30ppm, with bottle sheet process high-temperature fusion (temperature is 287 ℃), after extruding from screw extruder, (filtering accuracy is respectively: 50u through 3 grades of filtrations of fondant filter; 40u; 30u), spinning manifold (temperature is 287 ℃), high potential assembly (pressure is 13---15mp) offers the production special spinning jet that it produces special-shaped 75D/72F, again through uniform air flow (23 ℃ of wind-warm syndrome; Wind speed 0.6-0.7m/s; Wind speed irregularity≤10%), (0.5-0.7%) became as-spun fibre after cooling oiled, through reeling (speed 3200m/s), make the poy pre-oriented yarn, (speed is 600m/min in balance after-drawing distortion, temperature is 195 ℃, the d/y ratio is 2.0), after typing (temperature is 165 ℃) is reeled through oil (2%), through quality inspection, after the operations such as branch is grade packaged, the final special-shaped DTY fiber that forms " ten " font.
