Description
Technical field
The invention belongs to the invention belongs to technical field of textile processing, be related to one kind, to take into account Fiber Straightness uniform with sliver
The comb parallel connection production method of degree.
Background technique
Roller draft acts on the removal of fibre hook, depending on the crotch direction of fiber and the cooperation of drafting multiple.
By spinning theory it is found that in drafting process, the leading hooked fibre in strip is relatively difficult to stretch, and excessive drafting multiple can not stretch
Preceding crotch, it is necessary to can just be stretched with lesser drafting multiple；And trailing hooked fibre is easy to stretch, and drafting multiple is bigger, stretches
Effect is better.Therefore, high-quality yarn is spun, fibre morphology in the strip for needing to feed according to various processes, such as hook-type, crotch
Ratio etc., reasonable disposition each process drafting multiple improve the degree of stretching of fiber, reduce yarn unevenness, increase yarn strength.
The general comb spinning line of tradition after opening picking are as follows: cotton carding → drafting (2) → rove → spun yarn.Cotton carding exports the carded sliver
In 50% or more fiber be in rear crotch form, leading hooked fibre only accounts for 10% or so.In traditional Spinning process because cotton carding and
Drafting is two procedures, is processed respectively to fiber, produces strip commutation between various processes due to circle item, fiber
Crotch direction also changes correspondingly, so, in spinning, to obtain better processing effect and product quality, usually to each process
There is certain requirement in the feeding direction of drawing-off feature and strip.
There are suitable drawing-off and draft process in existing mixing in doubling step: in the close feelings of Double Drawing process total draft multiple
Under condition, refer to that the drafting multiple of slubbing drafting is small along draft process, the drafting multiple of extreme trace drafting is big, the final effect of this technique
It is that Fiber Straightness in strip is good, thus final yarn strength is high, but the strip uniformity is poor；Drawing-off refers to that slubbing drafting is led
It is big to stretch multiple, two drafting multiples are small, strip good evenness, but in strip fiber stretch it is unfavorable.It can thus be seen that existing
The mode that some cotton cardings and drafting are processed respectively, the draft process of drafting, which is arranged, cannot be considered in terms of fibre in the ripe bar uniformity and ripe bar
The requirement stretched is tieed up, one can only be sought.
It is longer for traditional spinning process, using the more drawback of equipment, automatic combined technique of spinning is by people's
Concern, Blowing carding, thickness connection, thin network connection etc., even thickness network connection technology are reducing labor and are improving equipment production effect
Rate and product quality etc. play positive effect, and comb parallel technology starts to be concerned by people in recent years.
Application No. is the authorization utility model patent of CN 201320844952 " drafting system for carding machine " and CN
201320851907 authorization utility model patent " carding machine with drawing-off module " individually discloses one kind and attached drawing-off
The carding machine and its drafting system of module, the alternative conventional drawing frame of drafting unit on carding machine, eliminate in old process
Mixing in doubling step.Shanghai Taipingyang Closroll Machinery Co., Ltd. of " cotton textile technology " publication of the 1st phase in 2015
Article " comb parallel technology application forecast " and " cotton carding or combing and mixing in doubling step join application No. is the patent of CN021576602
A kind of cotton carding or combing and the united method and apparatus of mixing in doubling step are all referred in the method and apparatus of conjunction ", after opening picking
General comb spinning line are as follows: comb parallel connection → rove → spun yarn, in order to meet in the general comb technique of tradition cotton carding to spun yarn be odd number
The sliver for combing parallel output is fed directly into rove by the requirement of procedure, effectively stretches yarn using the high draft multiple of spun yarn
The rear crotch of fiber in item, however since it lacks one of mixing in doubling step, strip is not obtained enough and is closed, uniformly mixing effect
Fruit not can guarantee, and it is irregular to increase final resultant yarn, in this regard, also illustrate to need in article through drawing frame autoleveller or drawing frame and
Carding machine dual autoleveller function makes up and improves, meanwhile, according to the commutation rule of strip, the sliver of rove is fed at this time
Before middle fiber based on crotch, and degree of stretching, since Roving Frames drafting multiple is bigger, is increased to preceding less than 90%
The difficulty that crotch stretches, actually to preceding crotch stretch be it is unfavorable, yarn quality is poor, in addition, strip in the techniqueflow
Suffered total draft multiple is smaller, therefore limited to the straightening of fibers effect in strip.
It is more from machine construction that the comb parallel connection technology proposed from above-mentioned document and patent, which can be seen that it and comb parallel connection,
Transformation and the angle for reducing process flow are set out, but do not configure draft process parameter according to the form of fiber in semi-finished product, are not had
Have to semi-manufactured goods quality and wherein the degree of stretching of fiber, fibre hook direction and crotch ratio cause enough attention.Cause
This needs a kind of comb parallel connection work that drafting multiple can be configured according to fibre morphology in semi-finished product in existing comb parallel technology
Skill, to take into account the degree of stretching of the semi-finished product strip uniformity and fiber.
Summary of the invention
The technical problem to be solved by the present invention is to existing comb each road Process configuration in parallel not to account for fibre in feeding strip
Form is tieed up, can not guarantee the uniformity of the degree of stretching of fiber and sliver in resultant yarn simultaneously.The present invention is directed to various processes semi-finished product
Middle fibre morphology, such as crotch direction and crotch ratio factor, reasonable disposition each process drafting multiple guarantee that final resultant yarn is irregular
It is small, and Fiber Straightness is good.
In order to achieve the above objectives, The technical solution adopted by the invention is as follows:
It is a kind of to take into account Fiber Straightness production method in parallel with the comb of evenness of yarn strip, spinning line are as follows: comb is in parallel → last
Road drafting → rove → spun yarn；
Wherein, comb parallel connection refers to that the carded sliver by the output of more carding machines feeds drafting in a drawing frame in parallel, the present invention
The carded sliver of more carding machines output directly and is closed and carries out drawing-off in feeding drawing frame and can be avoided and lead due to item bucket circle frees item
The carded sliver of cause commutates；For the present invention compared with the comb parallel connection technology that separate unit carding machine is connected with separate unit drawing frame, more carding machines are defeated
The carded sliver out directly and close carried out in one drawing frame of feeding drawing-off can be realized in the drafting process of the carded sliver the more carded slivers and
It closes, improves the uniformity and mixability of strip；
The total draft multiple for combing drawing frame in process in parallel is 6~12, due to the fibre entered in the sliver for combing process in parallel
For dimension based on trailing hooked fibre, the total draft multiple for combing drawing frame in process in parallel is larger, is conducive to trailing hooked fibre and stretches, and protects
Demonstrate,prove the Fiber Straightness in final resultant yarn；
The total draft multiple of drawing frame is 4~8 in extreme trace mixing in doubling step, due to entering in the sliver of extreme trace mixing in doubling step
Fiber is based on leading hooked fibre, and the total draft multiple of drawing frame is smaller in extreme trace mixing in doubling step, and advantageous leading hooked fibre stretches,
It is also beneficial to reduce the evenness fault of ripe bar, to guarantee that resultant yarn is uniform；
Compared with the method that document " comb parallel technology application forecast " is proposed, although the present invention has mostly used together simultaneously
Item, but the reasonability of technique and product quality significantly improve, the method that document " comb parallel technology application forecast " is proposed, because
Only pass through one of drafting, insufficient in the uniformity of strip and the mixability of fiber, final yarn quality is difficult to protect
Card；Early in 1976, " the duo-cards carded sliver is directly used in open-end spinning frame " one of Japanese " fibre technology message " publication
Wen Zhong mentions a kind of production technology of air spinning, only uses opening picking, cotton carding and air spinning three process resultant yarn；In May, 2005
In " designs and debugging production of Domestic Abbreviated Blowing carding Units " text of " cotton textile technology " publication, describes and exported by Blowing carding
The carded sliver directly carry out the process flow of Revolving cup spinning, but the quality index of final resultant yarn is not good enough；" World Textile is led within 2002
Report " paper " the general comb ring spun yarn of comb production in parallel and rotor yarn practice " delivered of the 3rd periodical Deng Liaoyipian Truetzschler company,
It refers to for the integrated drawing frame IDF that the said firm produces connecting with high-production card DK903 in article, spin out in test
Quality preferably medium count yarn and low count yarn；It can be seen that mixing in doubling step is saved, even the experiment of device manufacturer oneself,
It is only to spin the yarn low to uniformity requirements, which cannot use in the routinely yarn of production mean quality requirements above, nothing
Method guarantees the uniformity of final resultant yarn；
The total draft multiple of drawing frame in process in parallel is combed to multiply with the total draft multiple of drawing frame in extreme trace mixing in doubling step
Product is 24~80, i.e., drafting part and the product of drafting multiple in extreme trace drafting and the total draft of conventional Double Drawing in comb parallel connection
Multiple product is close, and in the case where the total draft multiple of Double Drawing is same as the prior art, slubbing drafting uses the present invention
Biggish total draft multiple, because of mainly trailing hooked fibre in strip at this time, drafting multiple is big, is conducive to straightening of fibers, though because
High draft causes to add irregular larger, but the total draft multiple of extreme trace drafting is small, and it is fine both to have improved preceding crotch in strip at this time
The degree of stretching of dimension (cotton net exports the trailing hooked fibre in the carded sliver and slubbing drafting), and improve irregular, therefore it says on the whole,
Fibre morphology enables draft process and fibre such as crotch direction and crotch ratio in comb parallel connection technology consideration semi-finished product of the invention
Dimension form is adapted, and can take into account suitable drawing-off and the draft process advantage of drawing-off using comb parallel connection technology of the invention, can
Take into account the quality requirement of the degree of stretching of fiber and the uniformity of sliver；
The total draft multiple of fly frame is 8~15 in Roving Frames, in traditional spinning line, average degree of stretching only 55%
The carded sliver of left and right becomes ripe bar after extreme trace drafting, and the degree of stretching that is averaged of fiber has reached 85% or so at this time, by changing
To when feeding rove, leading hooked fibre is in the great majority, and the high draft multiple Process configuration of rove is unfavorable to stretching for preceding crotch, because
Degree of stretching of this output rove only increases to 90% or so, and the present invention is by saving between original cotton carding and drafting this two procedures
Item and the commutation of item bucket are enclosed, the change in fibre hook direction in strip is avoided, with leading hooked fibre in the strip of traditional rove feeding
The case where occupying the majority is different, so that the fiber in the sliver of feeding Roving Frames is based on trailing hooked fibre, and thick due to entering
Fiber in the ripe bar of yarn process can increase the total draft multiple of Roving Frames based on trailing hooked fibre, Roving Frames
The larger trailing hooked fibre that is conducive to of total draft multiple stretch, the degree of stretching of fiber can reach 94% or more in rove, also favorably
In raising production efficiency；
It is which kind of fiber is curved when feeding spinning process since the degree of stretching of fiber is higher in rove in the present invention
Hook occupy the majority it is little to the influence for stretching fiber, the present invention feed spinning frame rove item either leading hooked fibre or after it is curved
Hook fiber, degree of stretching is very high, can achieve 90% or more, close to straight configuration, even if leading hooked fibre accounts in strip
Majority, but since Fiber Straightness is good, the high draft multiple of spun yarn is arranged and influences stretching for fiber；
Present invention reasonable disposition draft process parameter on the basis of considering the fibre morphology in strip is stretched improving fiber
Reduce yarn unevenness while directly spending, ensure that the quality of spinning, improve spinning efficiency.
As a preferred option:
A kind of as described above to take into account Fiber Straightness production method in parallel with the comb of evenness of yarn strip, more carding machines are
The number of units value range of 6~8 carding machines, carding machine is without being limited thereto, can appropriate adjustment, comb parallel connection in carding machine number of units difference
It itself does not have much affect to final yarn quality, but number of units difference will affect the carded sliver root of drafting part feeding in comb parallel connection
Number, and then influence to comb the total draft multiple of drafting in parallel part, carding machine number of units is more in comb parallel connection, then combs drafting part in parallel
