Summary of the invention
The objective of the invention is to propose a kind of cabling twisted composite yarn cabling, this complex yarn is with conventional yarn twisting equipment, synthetic fiber filament and short fibre yarn are carried out doubling twisting, and the complex yarn of making can have the advantage of long filament and short fibre yarn concurrently, realizes performance complement.
Purpose of the present invention is realized by following technical scheme: a kind of cabling twisted composite yarn cabling, form by synthetic fiber filament and short fibre yarn doubling twisting, the doubling twisting of described complex yarn twist with the fingers to the sth. made by twisting of short fibre yarn single thread to consistent, described synthetic fiber filament is terylene thread, POLYAMIDE YARNS or polypropylene fibre silk, and described short fibre yarn is the single thread of cotton, hair, viscose glue, acrylic fibers and Vinyon N spinning.
Compared with the prior art the present invention has following advantage:
1, Chang Gui yarn is for for the purpose of the Stability Analysis of Structures, ply twist is to all twisting with the fingers to opposite with single thread, but long filament and short fibre yarn are being carried out and twisting with the fingers compound tense, twist against twist causes short fibre yarn untwisting elongation, do not produce twist contraction and there is twisting filament through twisting, thereby making complex yarn be rendered as long filament stretches, short fibre yarn is wrapped in the outer outward appearance of line in the shape of a spiral of long filament, even adjust both tension force collocation, still can not eliminate this phenomenon, and the collocation at random because of screw line causes ripples line visible defect widely on fabric.The present invention adopts doubling twisting to twist with the fingers to twisting with the fingers to corresponding to mode with the single thread of short fibre yarn, can solve the problem of appearance of cabling twisted composite yarn cabling effectively.Choose the suitable twist, or carry out the dead twist processing of appropriateness, still can make yarn that stable structure is arranged.
2, the present invention selects suitable tension force collocation according to the boiling water shrinkage of synthetic fiber filament, make short fibre yarn and no twisting filament and twist with the fingers the tension force appropriate mix, guarantee that complex yarn still keeps long filament and staple fibre stressed evenly after the high-temperature process of dyeing and finishing processing, the yarn strength height, outward appearance is uniform.
3, the doubling twisting twist of the present invention is suitable.And twist with the fingers under the suitable prerequisite of tension force collocation, the twist of control doubling twisting makes the Stability Analysis of Structures of cabling twisted composite yarn cabling, the degree of tightness appropriateness, fabric feeling satisfies instructions for use, the anti-fluffing and anti-pilling performance is good.
4, the present invention can utilize conventional yarn twisting equipment to carry out the compound resultant yarn processing of long filament and short fibre yarn, can be adapted to the compound resultant yarn processing between the blended yarn of the pure spinning of existing various synthetic fiber filament and various different fibers and different fibre fractionations.Therefore, processing is convenient.
5, complex yarn of the present invention adopt when forward twisting and the twist when twisting with the fingers far below reverse frame and the twist, can realize higher Compound Machining speed.
6, the present invention can regulate the tension force collocation situation of long filament and short fibre yarn, can regulate the degree of exposure of staple fibre in yam surface within the specific limits, thereby change the feel of fabric.
7, the present invention has kept the advantage of resultant yarn and staple fibre performance complement, and can eliminate the cloth cover water corrugated fault that causes because of the not even optical characteristics of the structure of long filament and short fibre yarn is different.
The specific embodiment
Fig. 2 adopts the outward appearance of the yarn that prior art is spun into to amplify picture, Fig. 3 adopts the outward appearance of the yarn that the present invention is spun into to amplify picture, in this embodiment, that adopt 167 dtex terylene low elastic interlaced yarns and twist with the fingers tension force be 5cN, polyester-cotton blend 65/35 combing staple fibre yarn and to twist with the fingers tension force be 20cN.To and twist with the fingers composite yarn and apply respectively and single thread (Z sth. made by twisting+Z twist with the fingers, i.e. the present invention) and the reverse retwist twist of (Z sth.s made by twisting+S twists with the fingers, i.e. tradition twisting) (40 sth. made by twisting/centimetre) in the same way, the yarn that obtains is stretched curve by force as shown in Figure 1, its intensity does not descend to change because of sth. made by twisting as can be known; And as Fig. 2, shown in Figure 3, the outward appearance of the cabling twisted composite yarn cabling of (Z sth. made by twisting+Z sth. made by twisting) is much better than the outward appearance of the cabling twisted composite yarn cabling of (Z sth. made by twisting+S sth. made by twisting).
In tension force collocation with twist with the fingers under prerequisite reasonable in design, cabling twisted composite yarn cabling can be obtained good bar evenness and resultant yarn outward appearance, and can control the coverage rate of one of them fibre fractionation at fabric face within the specific limits, to adjust the hand feel characteristic of fabric.Process velocity is fast, producing cost is low.
