Background technology
Carbon fiber, it is high intensity, the new fiber materials of high modulus fibre of a kind of phosphorus content more than 95%.It is by
The organic fibers such as flake graphite are piled up along fiber axial direction to be formed, through microlite obtained from carbonization and graphitization processing
Ink material.Carbon fiber " soft outside but hard inside ", quality is lighter than metallic aluminium, but intensity is higher than steel, and has corrosion-resistant, high-modulus
Characteristic, be all important materials in defence and military and civilian aspect.At present, carbon fiber is applied in industry mainly as reinforcing material
Aspect, but seldom it is related to taking aspect, if can be used with clothes as protective garment, there will be an anti-cutting, high temperature resistant,
It is corrosion-resistant, the performance such as anti-electromagnetic shielding, although carbon fiber filament has very strong tensile property, fiber initial modulus in the axial direction
Height, shear strength is low, bends more rear frangibilities and unsuitable and skin contact.If textile staple is coated on carbon fiber filament beam
On, then can there are good wearability and feature.
If if carbon fiber filament beam and textile staple directly are spun into covering yarn, because chopped fiber can be grown in carbon fiber
Winding is twisted on tow, its active force can make carbon fiber filament beam produce certain transfer distortion on tangential, then because spinning
Tension force effect in journey, carbon fiber filament beam periphery long filament can be broken or distort, and cause weak ring on carbon fiber covering yarn to increase
More, axially strength declines, though still there is larger strength, compared with original carbon fiber filament beam, axially strength weakens significantly.
Thus, the present invention provides a kind of production method of carbon fiber core-spun single woven fabric, and the technique passes through in carbon fiber filament
Carbon fiber covering yarn can be spun into together with textile staple on cotton spinning frame using special pretreating process on beam,
The carbon fiber covering yarn being spun into can keep original strength in the axial direction, have in the tangential direction because there is the cladding of chopped fiber
There is certain bending resistance, be not easy embrittlement, then cause the fabric that processing obtains that there is excellent safeguard function.
The content of the invention
The purpose of the present invention is to provide a kind of carbon fiber core-spun single woven fabric production method, and carbon fiber is applied into the side of taking
Face, carbon fiber high-strength power is given full play of, anti-cutting, high temperature resistant is corrosion-resistant, the feature such as anti-electromagnetic shielding, protects human body not
It is hurt.
In order to achieve the above object, the technical solution adopted by the present invention is as follows:A kind of carbon fiber covering yarn, is grown by carbon fiber
Tow forms with chopped fiber, and the carbon fiber filament beam is heart yarn, and the chopped fiber is outsourcing yarn.
To realize the production of above-mentioned carbon fiber cored fabric, the present invention uses following production method, comprised the following steps:
The first step, the pretreatment of carbon fiber filament beam:Carbon fiber filament bundled tube is placed on warping creel, through warp sizing machine, drying
Machine is wound up into warp beam again to carbon fiber filament Shu Jinhang starchings by the carbon fiber filament beam that slurry coats;
Second step, warper beam unwinding:Carbon fibre tow in warp beam is unwound in order on the warping creel bobbin after repacking;
3rd step, covering yarn spinning:Pretreated core-spun yarn device of the carbon fiber filament beam through cotton spinning frame is fed
Enter front roller nip, chopped fiber rove feeds rear roller from cotton spinning frame horn mouth, and after leading through middle roller and front roller
Front roller nip is output to after the effect of stretching and obtains chopped fiber yarn, and chopped fiber yarn is at front roller nip to carbon fiber filament beam
Wrapped up, then both common twisting obtain carbon fiber covering yarn;
4th step, fabric processing:Carbon fiber covering yarn containing slurry is weaved, through desizing device, will be coated on
Slurry on carbon fiber filament beam is decorporated, cleaned, then is dried after conditioning liquid is nursed, and final processing obtains having certain pro-skin effect
Carbon fiber core-spun single woven fabric.
Using above-mentioned production technology, yarn quality preferably carbon fiber core-spun single woven fabric can be obtained.The first step is to carbon fiber
Endless tow is pre-processed, and slurry is coated on into carbon fiber filament beam surface, can strengthen the bonding force between monofilament, make monofilament outside
Sliding deformation is not easy under power effect, while makes endless tow entirety outer surface more mellow and full smooth, can be reduced and short fibre in spinning
The interaction force of dimension, reduce the generation of weak ring;Second step on bobbin, facilitates pretreated carbon fiber filament beam
Transport;3rd step spun core-spun yarn on cotton spinning core-spun yarn device, using carbon fiber filament beam as core filaments, outsourcing textile staple can
Strengthen the bending property of carbon fiber filament beam, protect core filaments, obtained carbon fiber covering yarn can be used to take;4th step is fine by carbon
Slurry in dimension covering yarn is decorporated, and is nursed and dried with conditioning liquid, can be improved covering yarn internal environment, pliability increase, be improved
Fabric total quality.
