Description
Technical field
The present invention relates to cotton textile technology field, and in particular to a kind of pure cotton knitting reduces the life of long thick long spun yarn defect with yarn
Production. art.
Background technology
With the extensive use of knitting product, a large family of the knitting yarn as yarn product, in recent years in textile
In the market has the appearance of larger development, particularly various new raw material and new structure yarn, is provided to knitting product
More wide market prospects and space.At present in various knitting yarn products, pure cotton knitting is still occupation rate of market with yarn
Maximum yarn product, but due to the difference of weaving principle and fabric construction, the quality requirement of pure cotton knitting yarn and woven use
Yarn differs widely, and predominantly bar is dry uniform, and particularly long slubbing, long details will be lacked, and otherwise such yarn defect is easily exposed to and knitted
Beyond the region of objective existence face, influences fabric quality, is also easy to cause broken yarn, influences production efficiency.
In order to solve the above technical problems, the reciprocal effect that each technological parameter grows thick long spun yarn defect to resultant yarn is reduced, simultaneously
Engineer testing number is reduced, now each operation technological parameter is studied, particularly to being easiest to produce long thick long spun yarn defect
Mixing in doubling step and spinning process, using orthogonal test method, slightly long spun yarn defect enters more than the 16cm larger to influence cloth cover length
Row process modification.
Traditional mixing in doubling step is：Sliver exporting speed 400m/min, front and rear roller shaft bearing 5 × 8mm of gauge, first break draft multiple
1.29 times, number of doubling 7.Although the technique can meet the requirement of general knitwear, it is required that high knitwear will expose length
Thick long spun yarn defect.
Traditional spinning process is：Spun yarn spindle speed 15000rpm, twist factor 358,17.5 × 25mm of roller gauge, first break draft
1.21 times of multiple, using back zone pressure bar.Although the technique can meet the requirement of general knitwear, require high knitwear just
Long thick long spun yarn defect can be exposed.
The content of the invention
The invention provides a kind of preparation method of high-quality pure cotton knitting yarn.
Goal of the invention：Reduce each technological parameter and the reciprocal effect of thick long spun yarn defect is grown to resultant yarn, while reduce technique examination
Number is tested, the quality of cloth made of raising.
A kind of pure cotton knitting reduces the production technology of long thick long spun yarn defect with yarn, including raw cotton sorting process, cotton cleaning process,
Carding step, combing process, mixing in doubling step, Roving Frames, spinning process and winding procedure.
The production technology that the mixing in doubling step is taken is：Front and rear 5 × 8mm of roller gauge, 1.17 times of first break draft multiple simultaneously close
Number 8.This group of technique is to choose the front and rear roller gauge being had a great influence to long thick long spun yarn defect, first break draft multiple, number of doubling etc.
Technological parameter carries out Orthogonal Experiment and Design, and the optimised process combination preferably gone out, such process combination reduces long thick long spun yarn
The generation of defect.
The production technology that the spinning process is taken is：After 17.5 × 25mm of roller gauge, 1.14 times of first break draft multiple, nothing
Area's pressure bar.Same this group of technique be choose the front and rear roller gauge being had a great influence to long thick long spun yarn defect, first break draft multiple, after
Whether the use of area's pressure bar carries out Orthogonal Experiment and Design, the optimised process combination preferably gone out, has by such process combination
Effect reduces the generation of long thick long spun yarn defect.
Using such technique, long thick long spun yarn defect is greatly reduced, the quantity of thick long spun yarn defect longer than traditional handicraft subtracts
50~65 ﹪ are lacked.
The grade of the raw cotton sorting process priority control raw cotton, length, mic value, maturity coefficient, short fiber content etc.
Index.
The cotton cleaning process is mixed using more marks, adjusts the principle of distributing cotton taken out less less, improves the uniformity of mixing.
The production technology that the carding step uses for：Quantitative 20.0g/5m, sliver exporting speed 130m/min.By such
Design improves the definition of web.
The production technology that the carding step uses for：Cylinder speed 470rpm, licker-in speed 860rpm.By such
Design reduces fibre damage and improves the rate of transform of the fiber to cylinder.
The bar of the combing process and roll up process rouleau number of doubling it is preferably more, using 24 and close.Pass through such design
Improve the transverse regularity of rouleau.
The combing process feeds He Duan Give cotton techniques using thin, gives the mm of cotton length 4.28.
The Roving Frames are using concentration draft process, roller gauge 10 × 22.5 × 40 mm, roving twist factor 115-
120。
Further supplement spun yarn spindle speed 15000rpm in the spinning process, twist factor 358.
Comprehensive beneficial effect of the present invention：This technique is drawn by experiment, using the preparation method of this technique, is reduced each
Individual technological parameter grows the reciprocal effect of thick long spun yarn defect to resultant yarn, while reduces engineer testing number, cloth made of raising
Quality.
Embodiment
