Abstract
The production process of Rodiya nylon 66 blended spun yarn is characterized by that the relative humidity of scutching procedure is 70%-75%, the relative humidity of drawing and roving procedure is 65%-70%, as compared with conventional cotton yarn spinning technology the roving quantum is lower by 15%-25%, the roving twist factor is 70-80, and the spinnin twist factor is 300-340, the drawing, roving and spinning procedures adopt double-layer soft pressing roller, the hardness of covering layer is Schopper hardness 62 plus or minus 3. The adoption of the said measures can make spinning process smooth and its resultant yarn quality is high.
Description
Technical field
The present invention relates to the spinning engineering field in the caused by spinning industrial production, be specifically related to the production technology of sieve ground Ya Nilong 66 staple blended yarn.
Background technology
Sieve ground Ya Nilong 66 short fibers that France Rhodia produces are a kind of nylon 66 fibers newly developed, have super soft, performance such as gloss is bright-coloured, sense of touch is good.This fiber is compared with other nylon 66 fibers, and fineness is thin, and spinnability is also different, adopts the production technology of common nylon 66 blended yarns just incompatible during spinning.Therefore, when this fiber and other fiber blends, must set up suitable technological parameter.
Summary of the invention
The objective of the invention is to work out corresponding technological parameter for the spinning engineering of sieve ground Ya Nilong 66 staple blended yarn.With cotton,, in the polyester cotton blending production engineering, comprehensively worked out the series of process measure, at sieve ground Ya Nilong 66 comprising following aspect with Modal or Lvocell.
(1) relative humidity of raising blowing, drafting and rove operation, the blowing parameter area is 70%～75%; The relative humidity 65%～70% of drafting and rove operation.
(2) environment temperature of drafting, rove operation is reduced to 23～25 ℃.
(3) for adapting to the low multiple drawing-off of spun yarn, rove quantitatively should be than conventional spinning yarn the time light by 15%～25%; The twist factor of rove is set at 70～80; The spun yarn twist factor is 300～340.
(4) drafting, rove, spinning process adopt double-deck soft pressurization roller, and clad hardness is Shao Shi 62 ± 3.
After having taked above-mentioned measure, spinning process is smooth, glues volume in blowing, comb and parallel cotton fibers prior to spinning, drafting, rove, the spun yarn process, is controlled in the required standard scope around roller, broken end phenomenon and formation yarn nep, and yarn quality is good.
Concrete implementing measure mode
Embodiment 1
1.7dtex the 32Ne knitting yarn is produced in * 40mm sieve ground Ya Nilong 66 and 2.15 grades of cotton 35/65 blending, process route is:
Nylon 66: grab cotton → opener → scutching cotton rolling → comb and parallel cotton fibers prior to spinning → in advance also;
Cotton: as to grab cotton → opener → scutching cotton rolling → comb and parallel cotton fibers prior to spinning → drafting → silver lap → combing;
Nylon 66+ cotton: mixed head also → mix two also → mix three also → rove → spun yarn.Blowing, drafting, rove operation relative humidity get 70% in the production engineering, 24 ℃ of drafting, rove process temperature, and regular roving feeding is lighter by 20% than routine, roving twist factor 75, spun yarn twist factor 315, the hardness of roller clad is Shao Shi 62.
Embodiment 2
1.7dtex * 40mm sieve ground Ya Nilong 66 and 1.3dtex * 40mm Modal 35/65 blending produce the 40Ne knitting yarn, process route is:
Nylon 66+Modal: hopper mixed cotton → grab cotton → opener → scutching cotton rolling → comb and parallel cotton fibers prior to spinning → head also → two also → rove → spun yarn.Except that the spun yarn twist factor is got 310, other technological parameters such as embodiment 1.
Embodiment 3
1.7dtex the 45Ne woven yarn is produced in * 40mm sieve ground Ya Nilong 66,1.67dtex * 38mm terylene, 2.15 grades of cotton 12/43/45 ratio blending, technological process is:
Nylon 66+ terylene: hopper mixed cotton → grab cotton → opener → scutching cotton rolling → comb and parallel cotton fibers prior to spinning → in advance also;
Cotton: as to grab cotton → opener → scutching cotton rolling → comb and parallel cotton fibers prior to spinning → drafting → silver lap → combing;
Nylon 66+ terylene+cotton: mixed head also → mix two also → mix three also → rove → spun yarn.
Except that the spun yarn twist factor is got 330, other technological parameters such as embodiment 1.
Claims (4)
1. the production technology of sieve ground Ya Nilong 66 staple blended yarn, the relative humidity that it is characterized in that cotton cleaning process is 70%～75%, the relative humidity of drafting and rove operation is 65%～70%.
2. blended yarn production technology as claimed in claim 1, the environment temperature that it is characterized in that described drafting, rove operation is 23～25 ℃.
