Abstract
The present invention discloses a ramie wet spinning method and an apparatus thereof, which directly fabricates long ramie spun yarn from ramie roving by a conventional spinning technology. The method comprises the processing steps: degumming ramie by the conventional (dry spinning) technology, carding, baking roving achieved through rough fabrication by a wet spinning machine, spooling and packing, wherein the ramie wet spinning machine is formed by modifying a flax wet spinning machine. An original arced frame is modified into a purpose-made breastplate which is installed between a front roller and a rear roller. The drafting interval of the breastplate is changed to 180mm to 260mm from 160mm. Yarn hair feathers and ramie granules of the fabricated ramie are obviously reduced, and thus, the quality is evidently increased. The yarn hair feathers are less than 20 roots in 10 meters. The ratio of breaking strength and dry spun yarn conservation rate is above 95 %. In addition, the present invention has great social benefits and economic benefits, and is suitable for ramie textile industry.
Description
Technical field:
The present invention relates to spinning method and the spinning machine of a kind of ramie, especially the method for ramie wet-spun yarn and wet spinning frame thereof.
Background technology:
The ramee spun yarn is utilized the dry-spinning technology usually.Because the ramee rigidity is big, spinnability is poor, and its resultant yarn filoplume is not only much but also longer, has a strong impact on the processing of back operation, and therefore, the resultant yarn filoplume that reduces ramie yarn is a ramie industry dream for many years.
It is investigated that the FP99 type fine spining machine that Italian Ge Tingnuo company produces can spin out the ramie yarn of less filoplume.But its yarn is behind groove drum, and the filoplume number sharply increases.Its main cause is that the ramee that rigidity is big when spinning is not twisted with the fingers in the yarn, and just is affixed on the surface of yarn under the effect of some water on the roller band.Under the effect of external force, very easily leave the main body of yarn, form filoplume.
Zhejiang Jin Ying joint-stock company attempted the wet-spun yarn of spinning ramie.Its method is that ramee is processed into the minimum fiber of difference in length, has spun the less ramie yarn of filoplume.But there is following shortcoming: 1. spinning process complexity, acquire a lot of equipment.2. row yielding is low.Lower more than ten percentage points than conventional (dry-spinning) technology and the technology of the present invention.3. yarn strength reduces significantly.The reduction amplitude is unfavorable for the processing of back operation more than 15%.This spinning method can't be promoted at present.
Summary of the invention:
For overcoming above-mentioned defective, the purpose of this invention is to provide a kind of method and device thereof of ramie wet-spun yarn, reach and reduce the ramie resultant yarn filoplume and purpose that the ultimate strength of yarn is not suffered a loss.
For achieving the above object, technical scheme of the present invention is as follows: a kind of method of ramie wet-spun yarn comprises with conventional (dry-spinning) technology degummed ramie-combing-also rough rove that gets again by wet spinning frame-drying-winder-one-tenth job contract skill process.Wherein: wet spinning frame is the flax wet spinning frame after improving, and spins out long numb spun yarn, and resultant yarn filoplume is at 7～20/10 meters, average ultimate strength on year-on-year basis dry-spun yarn 95%～105%.
A kind of device that is used for ramie wet-spun yarn method, this device is the flax wet spinning frame after improving, it comprises: creel, tank, front and back roller, plastron and spindle is characterized in that: between the roller, its drawing-off was spaced and is 180mm～260mm before and after plastron was installed in.
Described plastron is made of side plate, roller, crosspiece and downside pin, and notch is arranged on the side plate, and there is bearing at the roller two ends, and roller, crosspiece and downside pin are installed on the side plate.
The drawing-off of flax wet spinning frame spaced to be changed in 180mm～260mm scope adjustablely by 160mm, and before and after special mechanism-plastron is installed between the roller, these two conditions need not other change and can spin qualified ramie wet-spun yarn after satisfying simultaneously.
The invention has the beneficial effects as follows the long numb spun yarn of ramie rove spinning that can directly use common process.Resultant yarn filoplume is in 20/10 meters, and ultimate strength dry-spun yarn conservation rate on year-on-year basis improves the quality of ramie yarn more than 95%, and effect is remarkable, has very big social benefit and economic benefit, is fit to the ramie textile industry and uses.

The specific embodiment
Embodiment 1: 36 public pure ramie yarns of trial-production (write a Chinese character in simplified form 36
NThe R yarn).It is as follows with the present invention's's (wet spinning) contrast test with conventional method (dry-spinning) respectively to get common degummed ramie 1000kg:
1. the technological process of conventional method (dry-spinning) is as follows: degummed ramie-softening-heap storage-shredding-comb fiber crops-in advance also-combing-redoubling-recombing-four road drafting-pluckings-two is thick-and spun yarn-winder, wherein used fine spining machine is a ramie spinning machine, spins out 36
NThe resultant yarn filoplume of R yarn is 256/10 meters, 458/km of fiber crops grain, and single thread ultimate strength (being the resultant yarn brute force) is 672.16CN (li ox), other index sees table 1 for details.
2. the present invention's (wet spinning) technological process is as follows: degummed ramie-softening-heap storage-shredding-comb fiber crops-in advance also-combing-redoubling-recombing-four road drafting-pluckings-two is thick-and bubble rove-spun yarn-oven dry-winder, wherein used fine spining machine spins out 36 for the flax wet spinning frame after improving
N13.2/10 meters of the resultant yarn filoplumes of R yarn, 169/km of fiber crops grains, the two compares obvious minimizing with dry-spinning, and the resultant yarn brute force is that 694.71 compare difference with dry-spinning little, the equal no significant difference of other quality index sees table 1 for details.
The used fine spining machine of the present invention is to be improved by the flax wet machine to form, flax wet spinning frame is made of creel, tank, front and back roller, plastron and spindle, and the flax wet spinning frame after improving is the drawing-off between the roller of front and back spaced and changes in 180～260mm scope adjustable by 160mm, plastron is changed, and other parts are constant.As shown in Figure 1, plastron is made of side plate (1), roller (3), crosspiece (4) and downside pin (6), side plate has notch on (1), there is bearing (2) at roller (3) two ends, roller (3), crosspiece (4) and downside pin (6) are installed on the side plate (1), the tip designs of side plate (1) has jaw (5), is used to block downside pin (6).
