Keywords: flaxknittedyarn; clearing; processparameter0 introduction in recent years. With linen knitting needle from the type of development, linen knitting yarn requirements are increasing. Existing woven yarn can not meet the needle from the knitting machine knitting machine especially computer requirements, as it exists evenness and hemp particles, thick section of the high side and other shortcomings. Therefore, a reasonable choice is to improve the process route yarn knitted fabrics flax grades and the key to productivity. Here, we 1332M-type winders and ESPEROM / F Simple Machines Automatic network selection process and study participation effective to do an introduction. 1 use of raw materials and process requirements of 36 half-bleaching flax yarn linen yarn on the machine 28 colors before the test, the use of equipment according to specifications and technical requirements for machine, so that all parts have reached the requirements. 2, the choice of parameters of the gauge plate mechanical shed 2.1 yarn knitting yarn yarn making process is based on effective participation knitting machinery allow the effectiveness of flax yarn diameter values to determine,<a href="http://www.uggitalia.org" target="_blank" class="postlink">ugg italia</a>, it depends on the inner and tongue acupuncture needle hook grid-like teeth with the needle bed gap asked. 2.1.1 flax yarn knitting machinery theoretical maximum number of tongue through the needle with the needle bed gap grating teeth: 8 = (T-a-b) / 2 = (1.81-0.4-0.48 ) / 2 = 0.465mm which: needle-like teeth with the needle bed gap T gate of a stitch length (mm) r of a needle bar thickness (mm) b of a needle-like teeth bed thickness of the gate (nlm) d = diameter needle hook a (2x needle bar thickness) d = 1.38 A (2 × 0.4) = 0,58 ram them: d-l4 hook needle diameter knitting machines which allow the introduction of l4 flax yarn diameter through the theoretical maximum value of 0 .465 mm ~ 0.58ram. 2.1.2 Theoretical diameter of the wet spun linen yarn diameter d:-Nm36Nm flax yarn, flax yarn diameter d = 0.185ram28Nm theoretical diameter d = 0.210ram flax yarn knitting machinery by the maximum value (see Table 1): 4HeilongjiangTextile Table 12.1.3 without clearing the actual measurement taken at the l4 yarn flax yarn to knit on the knitting machine, and has been through rough sections, but the formation of defects through the rough sections, the formation of holes in the thick sections were measured and analyzed, measurement results in Table 2. Table 2 maggots section case (2o x) the average diameter (ram) sample passed through the rough section of the formation of defects of the maggots, but the formation of holes in the thick section of the sampling section sampling needle damage caused by the rough tongue section sampling 0.4880495O562O. 590 from the theoretical calculation and actual measurement results, quite different. This is because the yarn into a loop in the process under some tension caused by deformation. Thinner the yarn. In addition, the needle and needle-bed mattress grating gap size between the teeth with the tongue position of needle in the needle slot changes, the gap depends on the degree of thick section of soft and thick section length, thickness. So the measured value is greater than the theoretical value. Expansion coefficient to the yarn is usually a mass-produced by theoretical analysis and practical, we believe that l4 knitting machine flax yarn through the maximum diameter of more units appropriate for the 0.480ram. To 28Nm, 36Nm flax yarn as an example. Through the maximum diameter of 2.3-2.5 times the original yarn. 2.2 Electronic Yarn Harbin Linen Group Co.,<a href="http://www.ugg-schuhe.org" target="_blank" class="postlink">UGG Schuhe</a>, Ltd. mainly knitting yarn yarn parameters. 3 The results of the two yarn craft the following experimental results were compared (Table 3) Table linen yarn 328 of the indicators before and after mechanical flax yarn after yarn of 14 knitting machines weaving heritage, its production more efficient than the intact increased by 20%, weaving defect reduction of 20%. After the use of electronic yarn flax yarn woven in computerized flat knitting machine can be carried out smoothly,<a href="http://www.uggboots-jp.org" target="_blank" class="postlink">UGG ブーツ</a>, and its relatively flat knitting machine production efficiency increased by 2 times. 4 Conclusion from the test results, electronic yarn better than the mechanical yarn Yu thoroughly clean the yarn defects and improve the evenness, and no joints are far beyond the mechanical effect of yarn. Computerized flat knitting machine on the test, can be woven good, high efficiency, the appearance of better quality of their products,<a href="http://www.hunterbootssale.org/hunter-jimmy-choo" target="_blank" class="postlink">hunter jimmy choo</a>, the disadvantage is loss of high cost. Although mechanical yarn electronic yarn clearer than the removal rate is low,<a href="http://www.uggsmilano.org" target="_blank" class="postlink">ugg milano</a>, but after a large number of test weaving, hand knitting machine can meet the requirements, the advantage of low cost, low loss. Actual production, according to the equipment and quality requirements, select the appropriate process route and station parameters, are up to down the, speed, high-quality purposes.
