Description
Technical field
The present invention relates to ring spinning new technical fields, particularly relate to a kind of production for being electromagnetically shielded covering yarn
Method.
Background technique
Covering yarn refers to a kind of composite yarn by heart yarn and the combination of sheath yarn, short fine for outsourcing generally using long filament as heart yarn
Fiber (sheath yarn), feature are the combination by outer wrapping fiber and heart yarn, can play respective advantage, make up both sides not
Foot, maximizes favourable factors and minimizes unfavourable ones, optimizes the structure and characteristic of resultant yarn.Covering yarn produces existing more than 40 years history, and the demand of product is continuously increased,
Relative yarn kind is also enriched constantly.Currently, the whole world about more than 1,000 ten thousand ingot covering yarns, it is contemplated that every year will also be with 20-30
The speed of ten thousand ingots increases.Therefore, covering yarn has very vast market prospect.
Currently, the production technology of covering yarn is broadly divided into following three kinds: the first is that heart yarn is added on spinning process,
Form covering yarn, outer wrapping fiber first passes through Roving Frames and obtains required outsourcing rove, then outsourcing rove on spinning frame by
It is drawn and attenuated through drafting process by attenuating after rear roller feeding, core filaments are fed by feeding unit by front roller, and the two is twisted together
Covering yarn is formed, realizes outsourcing staple fiber to the cladding of heart yarn；Second is that heart yarn is added on wrap yarn machine, forms cored
Yarn, cotton yarn are first twisted to form cotton yarn bobbin, and heart yarn passes through the hollow spindle of wrap yarn machine by feeding roller on coating machine
Center, cotton yarn bobbin is fixed on hollow spindle, and by the rotation of cotton yarn tube and spindle, cotton yarn is wrapped on heart yarn, shape
At covering yarn；The third is that heart yarn is added by the method for doubling, forms covering yarn, sliver is processed into after spun yarn, in doubling
On machine, heart yarn is merged by feeding roller drawing-off with cotton yarn, is formed folded yarn, is wound into stock yarn bobbin, stock yarn bobbin
It is placed on chopped fiber two-for-one twisting machine, is twisted stock yarn by double-twisting machine spindle, form covering yarn.Wherein it is in the first manner
It is main, and covering yarn usually spins on ring spinning frame, wire guiding device of core-spun yarn is one of most important one component, is played
Fixed, the control heart yarn direction of motion the effect.Currently, wire guiding device of core-spun yarn is usually by a pair of of godet roller and a fixed dress
Composition is set, usually occurring heart yarn in use, direction is unstable in unwinding, tension suffered by heart yarn is uneven, yarn
The problems such as line Rose.
In view of this, the present invention provides a kind of production method for being electromagnetically shielded covering yarn, rotated by using being driven by a motor
Device realize feeding before the looping of spandex and stainless steel filament act on, the double long filament looping structures then formed between the two
It is integrally fed as heart yarn and carries out cored effect between the yarn by drawing-off effect, to obtain required cotton/spandex/no
Become rusty ladle heart yarn, and realizing has the production of more double filament core-spun yarns of compact structure, improves cored effect, and it is comprehensive to improve resultant yarn
Quality.

The 4th feed carrier is connected on bar, the 4th feed carrier and the first feed carrier, the second feed carrier, third guide fill
The structure set is identical, and the 4th feed carrier is fixed on left branching rod and right strut by the 4th pitman, and the described 4th connects
The left end taken over the baton is fixedly connected with left branching rod, and the right end of the 4th pitman is fixedly connected with right strut；When spinning, covering yarn
Device is fixed on the reel cage of spinning frame by connecting up bar, and pure cotton rove is fed by the horn mouth of the rear roller front of spinning frame
Enter, and after through rear roller, middle roller, front roller drawing-off effect after by front roller jaw export, obtain pure cotton yarn, spandex
Long filament is by penetrating heart yarn feed arm by the upper port of upper heart yarn feed arm after heart yarn cylinder actively export, then from the first feed carrier
The top of yarn guiding trough of yarn guiding wheel pass through, then pass through, then from the lower part of the yarn guiding trough of the yarn guiding wheel of the second feed carrier
Passed through from the top of the yarn guiding trough of the yarn guiding wheel of third feed carrier, then by the lower port of lower heart yarn feed arm be pierced by heart yarn feed
Enter bar, finally pass through from the lower part of the yarn guiding trough of the yarn guiding wheel of the 4th feed carrier, while motor drives rotating roller by belt
Rotation, the direction of rotating roller rotation and the orientation of the pure cotton yarn twisting twist are consistent, and stainless steel filament is by heart yarn cylinder active
It is passed through after export by the top of the yarn guiding trough of the yarn guiding wheel of the 4th feed carrier, then stainless steel filament and spandex filament are fed jointly
Enter front roller rear portion, the two is acted on via the pressing of front roller jointly, at this time due to the rotation of rotating roller, then drives first to lead
Yarn feeding device, the second feed carrier, the rotation of third feed carrier yarn guiding wheel, then drive spandex filament rotation long to generate spandex
The silk winding twist to fill positioned at third guide after one end of spandex filament and stainless steel filament is held by front roller pressing
The spandex filament set between front roller is constantly wrapped on stainless steel filament under the action of spandex filament winds the twist, is obtained
Heart yarn before feeding, the heart yarn before then feeding are exported by front roller nip after holding via front roller pressing, are fed at this time
Preceding heart yarn is located at the centre of pure cotton yarn, and then under the action of twisting the twist, pure cotton yarn is constantly twisted into outer
Heart yarn after feeding is wrapped up, obtains final cotton/spandex/stainless steel covering yarn by packet yarn, due to holding disappearing for point during this
Lose so that in heart yarn spandex filament on stainless steel filament spandex filament winding the twist disappear, then make spandex filament from
It is constantly unwound on stainless steel filament, but pure cotton yarn twisting simultaneously is twisted at outsourcing yarn and when wrapping up heart yarn due to twisting
Degree is identical with the spandex filament winding orientation of the twist, so that spandex filament is prevented from from the unwinding on stainless steel filament, then
So that feeding after heart yarn in spandex filament a part retain spandex filament winding the twist under with weak twist effect be wrapped over not
It becomes rusty on steel long filament.Specifically includes the following steps:
Step 1: by cotton fiber through Blowing carding, pre-drawing, item and roll up, combing, drafting, Roving Frames process to obtain pure cotton it is thick
Yarn；Blowing carding uses BO-A type automatic plucker, SP-MF multifunctional separator, MX-I6 multi-mixer, CL-C1 kirschner beater
Scutcher, YQ600H different fine machine, SP-DX heavy-duty, TC5-1C carding machine, pre-drawing use FA313B pre-drawing machine, and item is simultaneously
Volume uses CL15 draw frame and lap machine combined, and combing uses CJ-60 combing machine, and drafting uses HSR1000 drawing frame, and rove uses
JWF1415 fly frame；
Step 2: pure cotton rove, spandex filament, stainless steel filament to be fed to the QFA1528 spun yarn for installing core-spun yarn device additional jointly
Machine, processing obtain final cotton/spandex/stainless steel covering yarn.
