Abstract
The invention relates to a technology for producing flat filaments of woven cloth by plastic processing. After entering an extruder, raw materials are subjected to external heating at a temperature of 190-250 DEG C, and are cut by a screw and a cylinder, and the materials are extruded quantitatively under fixed pressure after almost all plasticizing is completed; the materials are subjected to film head forming, and become a molten thin film, and the thin film enters cooling water; the thin film is cut into blank filaments by a blade after cooled; the blank filaments are subjected to high multiple extension in a drying oven with a relatively high temperature till the flat filaments are formed; finally, the flat filaments are subjected to heat setting on a heat roller, are preshrunk under the condition of low drawing speed, are treated by a cold roller at a low temperature, and finally are wound and formed by a disk differential type tension winding system. The technology has the advantages that the speed of cooling the high-temperature thin film at a mold orifice of the extruder head is high, the degree of crystallinity is small, and in heating and stretching processes, crystals are easy to soften and stretch, but not easy to fracture, therefore, the continuity of a production process is improved, and the toughness of finished filaments is improved.
Description
Technical field
The invention belongs to plastic woven cloth product manufacturing technical field, particularly relate to a kind of plastic processing and produce woven cloth flat filament technique.
Background technology
Polywoven Bag is that raw material is made plastic flat fiber, after again flat filament being made cloth, according to the sack that certain size is sewn into, current Polywoven Bag is with acrylic resin for primary raw material, in the operation of its production, flat filament is the critical process of braided bag production line also known as wire-drawing process, drawing process excellent, directly affects inherent quality and the presentation quality of product.
In current flat filament technique, thermal finalization is abundant not, it is impossible to eliminate the internal stress that the nascent flat filament of polypropylene produces in drafting process, so that the intensity of flat filament finished silk and toughness are relatively low, wire drawing linear velocity and line density deviation are big, and mechanical performance is not high.
Summary of the invention
The purpose of the present invention is that and overcomes above-mentioned the deficiencies in the prior art, and provides a kind of plastic processing to produce woven cloth flat filament technique, and this technique can be effectively improved intensity and the toughness of polypropylene finished silk.
The technical scheme is that
A kind of plastic processing production woven cloth flat filament technique, after raw material enters extruder, under the shearing mutually of the external heat of 190-250 DEG C and screw rod and machine barrel, material, after almost all plastifying, is extruded by quantitative, level pressure.Through film head molding, the thin film becoming molten enters in cooling water.After cooling, thin film is cut into embryo silk by blade.Embryo silk in the baking oven that temperature is higher by super drawing until formed flat filament.Then flat filament thermal finalization on hot-rolling, gives contraction, and is processed at low temperatures by cold roller when low hauling speed, through disk differential type tension wrap-up system rolling molding after.
The cooling step that in described flat filament technique, molten thin film enters in cooling water adopts cold water quick refrigeration.
The invention has the beneficial effects as follows: the present invention is fast to the high temperature film rate of cooling of cross-head die orifice, and degree of crystallinity is little, adds crystal in hot-stretching step and easily softens, it is easy to stretch, not easy fracture, improves the seriality of production process, improves the toughness of finished silk.
Accompanying drawing explanation
Fig. 1 is flat filament process chart of the present invention.
Detailed description of the invention
A kind of plastic processing production woven cloth flat filament technique, after raw material enters extruder, under the shearing mutually of the external heat of 200 DEG C and screw rod and machine barrel, material, after almost all plastifying, is extruded by quantitative, level pressure.Through film head molding, the flat film becoming molten enters in cooling water, cools down rapidly.After cooling, thin film is cut into embryo silk by blade.Embryo silk in the baking oven that temperature is higher by super drawing until formed flat filament.Then flat filament thermal finalization on hot-rolling, gives contraction, and is processed at low temperatures by cold roller when low hauling speed, through disk differential type tension wrap-up system rolling molding after.
Claims (2)
