Abstract
The invention discloses a method for making stretch yarn through drawing. The method includes making nylon into small particles, drying the small particles, and performing fusion drawing on the nylon particles; cooling the nylon after yarn drawing, pre-drawing the nylon after being cooled, and applying oil on the nylon for bundling; reducing tension of nylon yarn, winding and twisting the nylon under small tension, and completing winding and quality inspection of the twisted nylon. By the above mode, the method has the advantages of high reliability, high elasticity, high tension, convenience in making, simple process, high production efficiency, simplicity in process changing, low cost and the like, and has wide market prospect in chemical fiber market.
Description
Technical field
The present invention relates to chemical fibre field, particularly relate to a kind of elastic filament stretching method for making.
Background technology
That utilizes that synthetic fiber thermoplasticity makes has permanent non-linear coiled, a fluffy and resilient chemical-fibres filaments.Common are low elastic polyester filament and nylon stretch yarn.Due to elastic filament resilience fast, can be used for manufacturing stretch shirt trousers, socks etc., existing elastic filament undercapacity, and extensibility is lower, makes elastic filament application limited.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of elastic filament stretching method for making, by predraft and when stretching, twists, and improves the elasticity of elastic filament; Utilize twisting, improve elastic filament intensity, there is good performance; There is the advantages such as unfailing performance is high, good springiness, pulling force is strong, easily manufactured, technique is simple, production efficiency is high, process change is simple, cheap, in chemical fibre market, have market prospects widely simultaneously.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of elastic filament stretching method for making is provided, comprise: 1) nylon is made granule and dry, 2) nylon particle is sent into and in feeding screw, is carried out melt drawing, 3) nylon after wire drawing is carried out fast cooling, 4) cooled nylon is carried out to predraft the boundling that oils, 5) reduce the pulling force of nylon yarn and under less pulling force, nylon yarn carried out around volume twisting, 6) nylon that completes twisting is around volume quality inspection.
In a preferred embodiment of the present invention, described quick cooling employing mode is water-cooled.
In a preferred embodiment of the present invention, the 15%-25% that described predraft tensile elongation is unit length.
In a preferred embodiment of the present invention, described in reduce nylon yarn pulling force operation for nylon yarn being stretched as to the 5%-10% of original length.
In a preferred embodiment of the present invention, the nylon yarn quantity of described twisting step is 6-10 root, and the described twist is 60-100.
The invention has the beneficial effects as follows: a kind of elastic filament stretching of the present invention method for making is twisted by predraft and when stretching, and improves the elasticity of elastic filament; Utilize twisting, improve elastic filament intensity, there is good performance; There is the advantages such as unfailing performance is high, good springiness, pulling force is strong, easily manufactured, technique is simple, production efficiency is high, process change is simple, cheap, in chemical fibre market, have market prospects widely simultaneously.
The specific embodiment
Below the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making all other embodiment that obtain under creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the present invention comprises:
A kind of elastic filament stretching method for making, comprise: 1) nylon is made granule and dry, 2) nylon particle is sent into and in feeding screw, is carried out melt drawing, 3) nylon after wire drawing is carried out fast cooling, 4) cooled nylon is carried out to predraft the boundling that oils, 5) reduce the pulling force of nylon yarn and under less pulling force, nylon yarn carried out around volume twisting, 6) nylon that completes twisting is around volume quality inspection.
Described quick cooling employing mode is water-cooled, can quick cooling silk thread, there is comparatively good material behavior.
The 15%-25% that described predraft tensile elongation is unit length, improves elastic properties of materials.
The described pulling force operation that reduces nylon yarn, for nylon yarn being stretched as to the 5%-10% of original length, is conveniently twisted thread, and guarantees elastic yarn performance.
The nylon yarn quantity of described twisting step is 6-10 root, and the described twist is 60-100, has good intensity and elasticity.
The beneficial effect of a kind of elastic filament stretching of the present invention method for making is:
One, by predraft and when stretching, twist, improve the elasticity of elastic filament;
Two, utilize twisting, improve elastic filament intensity, there is good performance;
Three, there is the advantages such as unfailing performance is high, good springiness, pulling force is strong, easily manufactured, technique is simple, production efficiency is high, process change is simple, cheap, in chemical fibre market, have market prospects widely simultaneously.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
