Background technique
In recent years, the yearning and pursuit with people to good life, to the comfort, health, safety of garment material
The requirement of property and the feature of environmental protection is higher and higher.As movable time increases people outdoors, easy dress and gym suit interpenetrate,
The trend to combine together is also increasingly by the favor of the majority of consumers.The fabric of this kind of clothes requires have good comfort, again
It needs, once there is situation soaked with sweat, skin will not be pasted when movable heartily and generate cold wet feeling.The performance of fiber is direct
Influence the function of fabric, therefore, fiber used need to have it is comfortable, lead wet performance.
For natural fiber by taking cotton as an example, moisture pick-up properties is good, comfortable and easy to wear, but when perspiring amount is slightly larger, cotton fiber meeting
Because of moisture expantion, gas permeability declines and pastes on the skin.Meanwhile moisture divergence speed is also relatively slow, causes one kind to human body
Cold wet feeling；For synthetic fibers by taking terylene as an example, water imbibition is small, and water vapour permeability is poor, easily causes dress due to its accumulation of static electricity
When generate the trouble tangled, be especially easy to produce feeling of oppression and heat in activity；Special-shaped polyester fiber have perspire, wet guiding function,
But such material surface is coarse, and comfort is poor.
Summary of the invention
In view of the deficiencies of the prior art, the purpose of the present invention is to provide a kind of production works for coating modified polyethylene fiber
Skill.Coating modified polyethylene fiber prepared by the present invention has the characteristics that soft, to lead wet, quick-drying, spinnability excellent.

(1) polyethylene and polyester are passed through into screw rod melting extrusion respectively, obtain molten polyethylene material, molten polyester material；
(2) in terms of mass ratio 45-70:30-55, molten polyethylene material is coated on the surface of molten polyester material, obtains polyester
Modified polyethylene；The coating is to realize molten polyester material by being loaded with the bath of molten polyethylene material with thread；
(3) polyethylene of polyester modification is cooling, finish then is added on the surface of polyethylene, obtains the modified poly- second of coating
Alkene fibre semi-finished products；
(4) coating modified polyethylene fiber semi-finished product stretched, crimped, thermal finalization, obtain coating modified poly ethylene
Fiber.
Preferably, the polyester is polyethylene terephthalate, polypropylene terephthalate, gathers to benzene two
One of formic acid butanediol ester.
Preferably, the flow of the thread is the hole 0.4-0.5g/min.
Preferably, described stretch includes successively carrying out hot water stretching, steam stretching, will coating modified polyethylene fiber half at
Product are stretched to 5-8 times of raw footage；The temperature that the hot water stretches is 70-90 DEG C, and the temperature of steam stretching is 120-130 DEG C.
Preferably, the temperature of the thermal finalization is 80-90 DEG C.
The coating modified polyethylene fiber that above-mentioned production technology obtains.
Beneficial effects of the present invention
(1) polyethylene that the present invention uses, guarantee fabric hand soft comfortable, while water repellent, water conservancy diversion, no cold wet feeling, out
Sweat without stick together sense；The intensity of fiber entirety can be improved in the polyester used, ensure fiber spinnability and cloth necessary to intensity and
Performance；Using surface of polyester coating polyethylene, being formed by skeleton, polyester of polyethylene is the coating modified poly ethylene of reinforcing material
Fiber；The coating modified polyethylene fiber of preparation has the characteristics that soft, to lead wet, quick-drying, spinnability excellent；Present invention melting is poly-
The surface of ester material coats molten polyethylene, and the mode of coating is with thread by molten polyester material by being loaded with molten polyethylene material
Bath ensure that polyethylene is fully contacted with surface of polyester, and polyethylene is made equably to wrap up the surface of polyester, polyethylene and poly-
Ester combines more closely, improves modified effect；The mass ratio control of molten polyethylene material, molten polyester material ensure that poly-
The thickness of ethylene skeleton, it is ensured that coat the intensity and lightweight flexible of modified polyethylene fiber.
(2) the coating modified polyethylene fiber that the present invention obtains has soft characteristic, and the density of polyester is 1.38g/
cm3, and the density of polyethylene is about 0.95g/cm3, using surface of polyester coating polyethylene, formed using polyethylene as skeleton, polyester
For the coating modified polyethylene fiber of reinforcing material, the high-intensitive advantage of polyester fiber had both been realized, while having overcome polyester
Fiber applications big disadvantage of density when weaving, effectively mitigates the weight of cloth.
(3) simple production process of the invention, high production efficiency, obtained coating modified polyethylene fiber intensity is high, draws
It is unlikely to deform after stretching, cohesive force height, it is good to be not likely to produce electrostatic, comprehensive performance.
Detailed description of the invention
Fig. 1 is the production technological process for coating modified polyethylene fiber.
