Abstract
The invention relates to a spinning process, in particular to modification on a method of compounding a plurality of single silk yarns into one silk plied yarn. The method includes: 1, partly twisting the non-twist single silk yarns into N primarily twisted silk single yarns; 2, twisting the N primarily twisted single silk yarns into M secondarily twisted silk yarns of certain twist (N being not smaller than 2); 3, re-twisting the M secondarily twisted silk yarns into a compound silk plied yarn of certain twist (M being not smaller than 2). The method has the advantages that bending rigidity of the silk plied yarn is improved significantly and weaving is facilitated.
Description
Technical field:
The present invention relates to spinning technique, relate in particular to the improvement by the method for the synthetic silk strand of some silk single thread.
Background technology:
Strand is to be formed through partnership process by some single thread, strand is weaved and is become strand fabric through knitting or tatting loom, the quality of strand has directly affected the quality of fabric, the bending stiffness of strand is the key factor that affects strand facing anti-crease performance, the fabric being made into the high strand of bend stiffness, the wrinkle resistance of this fabric is all right.The method of the synthetic silk strand of silk single thread generally adopting in the industry at present, is that disposable the closing of some no twist silk single thread (silk single thread refers to the thread being comprised of some raw silk fibers that reeling mill produces) is twisted to silk strand.The deficiency of this method is: for the ease of weaving, just require the twist of strand can not be too high, otherwise strand is the easily knotting or agglomerating of this strand under the effect of resiliency, being unfavorable for face weave, easily there is the lines of crosspiece or density in fabric outward appearance, and presentation quality is poor.But if the twist of strand is not high, cause again the bend stiffness of strand on the low side, do not reach the requirement that improves facing anti-crease performance.Experimental result also shows: compare with silk single thread fabric, the wrinkle resistance of this silk strand fabric does not improve significantly.
Can significantly improve at present silk strand bending stiffness and facilitate again woven silk strand synthetic method there is not yet, also in data and media report, not find.
Summary of the invention:
For the existing above-mentioned deficiency of prior art, technical problem to be solved by this invention is the method that the synthetic silk strand of a kind of silk single thread will be provided, it can obviously improve silk strand bending stiffness, conveniently weave simultaneously.
In order to solve the problems of the technologies described above, the scheme of technical solution problem of the present invention is: the method for the synthetic silk strand of silk single thread, and (1) adds certain twist by the silk single thread of no twist, forms first twist silk single thread; (2) again by first twist silk single thread twisted described in N root, be formed with the retwist silk line (N >=2) of certain twist; (3), by the twisted again of retwist silk line described in M root, be formed with the synthetic silk strand (M >=2) of certain twist.
Adopt after such scheme, owing to first the silk single thread of no twist being added to certain twist, form first twist silk single thread, improved the coefficient of friction between silk fiber in silk single thread, again by the twisted add certain twist again of first twist silk single thread described in N root, form retwist silk line, further improved the coefficient of friction between silk fiber between silk single thread and in silk single thread, after again by the twisted add certain twist again of retwist silk line described in M root, form synthetic silk strand, again improved the coefficient of friction between silk fiber between silk single thread and in silk single thread, and the twist of each silk single thread in synthetic silk strand.
Because the fineness of the synthetic silk strand of twisted some first twist silk lines used may be incomplete same, in the process of plying, easily make the rate of change of synthetic silk strand cross section larger, cause the bend stiffness of this synthetic silk strand to reduce, the wrinkle resistance of woven fabric is just poor, therefore, this synthetic silk strand will improve the bar evenness of this synthetic silk strand through the processing of strand comb line device, and the cross section rate of change of this synthetic silk strand is controlled in very little scope.Synthetic silk strand after strand comb line device is processed has met three factors that improve silk strand bending stiffness preferably: in silk strand, the twist large, silk strand of the coefficient of friction between silk fiber is optimum, the rate of change of silk strand cross section is little between each silk single thread and in silk single thread.
The twist of strand is a key index that affects the bending stiffness of strand, in strand twisting process along with the raising of the twist, bending stiffness is corresponding improve also, still, when the twist bring up to a certain numerical value time, bending stiffness just no longer improves and has declined on the contrary, when maximum with bending stiffness, the corresponding twist is just defined as the critical twist of this strand, and therefore, the twist of described synthetic silk strand and critical twist approach but be no more than critical twist, at this moment, the twist of this silk strand is optimum.
The invention has the beneficial effects as follows: by increasing, in synthetic silk strand, between each silk single thread and in silk single thread, the twist optimum of silk strand is synthesized in the coefficient of friction between each fiber, control, the cross section rate of change of synthetic silk strand is controlled in very little scope, the bend stiffness of described synthetic silk strand is compared by the some disposable bend stiffness that close the silk strand of sth. made by twisting of no twist silk single thread and be significantly improved, with the wrinkle resistance of the woven fabric of described synthetic silk strand, obtained remarkable improvement.Meanwhile, because the method is the twist that minute three steps successively improve each silk single thread in described synthetic silk strand, and the twist of described synthetic silk strand itself not bery high, be conducive to weave fabric and fabric outward appearance density evenly, fabric presentation quality is good.
The reference twist number range of described first twist silk single thread, retwist silk line, synthetic silk strand is 80-360T/m.
Indefiniteness embodiment:
The method of the synthetic silk strand of silk single thread, (1) adds S sth. made by twisting by the silk single thread of four no twist, and the twist is 160T/m, forms first twist silk single thread; (2) 2 first twist silk single thread are twisted with the fingers to twisted with S again, the twist is 120T/m, forms 2 retwist silk lines; (3) these 2 retwist silk lines are twisted with the fingers to twisted again to the synthetic silk strand by 4 silkworm single thread twisteds that the formation twist is 140T/m with S.
Claims (2)
1. the method for the synthetic silk strand of silk single thread, is characterized in that: (1) adds certain twist by the silk single thread of no twist, forms first twist silk single thread; (2) again by first twist silk single thread twisted described in N root, be formed with the retwist silk line (N >=2) of certain twist; (3), by the twisted again of retwist silk line described in M root, be formed with the synthetic silk strand (M >=2) of certain twist.
2. the method for the synthetic silk strand of silk single thread according to claim 1, is characterized in that: the reference twist number range of described first twist silk single thread, retwist silk line, synthetic silk strand is 80-360T/m.
