Abstract
Provided is a textile spinning process for cellulose fiber Tufcel, which is characterized in that: improving the pressure of the blowing covered roll, controlling fiber moisture regain, reconfiguring the card covering of the card cylinder, doffer and cover board, drawing and roving which reduces the roving twisting coefficient in the environment of low temperature and high moisture and adopts the soft covered roll, reducing the front middle roller center distance in the spinning machine. The invention improves the blowing blocking phenomenon, controls the unevenness of the nep and weight of the carding silver, eliminates phenomenon of the drawing and twist of roving, reduces the broken ends and improves the resultant yarn quality and drawing to the fiber by spun yarn.
Description
Technical field
The present invention relates to the spinning engineering field in the caused by spinning industrial production, specifically be meant the spinning process of a kind of tencel cellulose fiber Ta Fusaier.
Background technology
Ta Fusaier is a kind of cellulose fibre of new generation, introduce advanced technology and high-quality wood pulp and the advanced spinning equipment production that Japanese Japan is spun by Dandong Japan special fibre Co., Ltd, through the spinning, weave with dyeing and finishing after shade fabric bright-coloured, is rich in gloss, feel is smooth, and is soft elegant, moisture transported permeable, comfortable and easy to wear, have more performance than the product of allied fiber model.It is thin that Ta Fusaier fiber and the viscose glue cellulose fibre similar with other compared fineness, the intensity height, and wet dry strength is than big, and interfibrous cohesive force, frictional force are strong, and spinnability is different.Therefore, adopt the conventional production process of viscose glue spinning just incompatible during spinning, controlling fiber is at the speed change point and the drafting force of process effectively, take place around roller easily, go out hardhead, broken end phenomenon how, spun yarn slubbing is many, and is powerful low, the cloth cover poor flatness that weaves, clouding is many.Therefore, during the Ta Fusaier fiber spinning, must set up the working process parameter of these fibre property characteristics of being fit to.
Summary of the invention
The problem to be solved in the present invention is the characteristics at the Ta Fusaier fiber, formulates a kind of suitable spinning process, with improve that the Ta Fusaier pure fibers is spun and with yarn quality cotton, the fine denier polyester blended yarn.
For addressing the above problem, spin or taked during blending following technological measure in the Ta Fusaier pure fibers:
1. improve blowing and become press roll pressure, increase 18%～22%,, prevent sticking volume to improve producing wound laps than spunbond glue; The fiber regain is controlled at 9%～11%, and to avoid the sticking volume of Ta Fusaier fiber fluffy, the weight that influences the debatching quality and the carded sliver is irregular.
2. the card clothing model during to the spunbond glue of carding machine is matched again, Bearded-needle knitted cloth is used 2820 * 1560 types instead by 2525 * 1550, doff clothing is used 4532 * 2080 types instead by 4030 * 1880, flat-clothing is used 702 types instead by JTST45, improve fiber from doffer's the rate of transform and doff clothing grasping force to fiber, guarantee fiber web output smoothly, reduce carded sliver cotton knot.
3. drafting, rove operation adopt the process environments of low temperature and high relative humidity, and to eliminate around the roller phenomenon, the production environment temperature of drafting, rove operation is controlled at 23～25 ℃, and relative humidity is controlled at 65%～70%.
4. roving twist factor is reduced to 68～70 by routine, goes out hardhead, many, the dried poor situation of bar of resultant yarn slubbing to eliminate spun yarn.
5. drafting, rove, spinning process adopt soft pressurization roller, and clad hardness is Shao Shi 63.
6. in the spinning process, the centre-to-centre spacing of preceding middle roller narrows down to 38～40mm, has broken through the boundary that at present preceding middle roller centre-to-centre spacing minimum can only reach 42mm.Reduced the district of swimming like this, it is stable that fiber speed change point is concentrated, and improved the control to fiber, and yarn strength, bar evenness are significantly improved.
Taked after the above-mentioned technological measure, the spinning production process is smooth.The sticking volume of blowing phenomenon is improved; The cotton knot of the comb and parallel cotton fibers prior to spinning carded sliver and heavy irregular controlled; Drafting, rove are eliminated around the roller phenomenon, and broken end reduces, and the semi-products inherent quality improves; Spun yarn to the drawing-off of fiber control be improved significantly, yarn quality significantly improves.
The specific embodiment
Embodiment 1.
