Description

Sirospun spendex core-spun particle yarn

Technical field

The utility model relates to a kind of sirospun spendex core-spun particle yarn.

Background technology

The spandex silk belongs to the polyurethane series fiber, is a kind of highly elastic fiber, and the maximum characteristics of spandex fibre are to have bigger extensibility, slowly stretch, and its degree of stretching maximum can reach between 450～600%, can restore to the original state rapidly again after the power of removing is lax.

Spandex core-spun yarn commonly used at present all is inner core with the spandex filament, outsourcing yarn fiber layer; Its production method is: the staple fibre rove is fed draw zone from rear roller, and spandex filament is from the front roller feeding, and with the staple fibre rove yarn merging after the drawing-off, twisting forms spandex core-spun yarn.The staple fibre rove of outsourcing can be used natural fabrics such as cotton, hair, fiber crops, silk.Spandex core-spun yarn has good extensibility and nerve, has good wearability of outsourcing staple fibre and surface characteristics simultaneously.

The production method of siro-spinning yarn is: with two same draw zones of the parallel feeding fine spining machine of rove that keep a determining deviation, after the drawing-off, by two single thread yarns of front roller output, on two single thread yarns a small amount of turn is arranged respectively, finally merge together, further twist into " the match doff " of similar strand.In the Siro-spun yarn line structure, resultant yarn and sub-thread all have certain twist, therefore, in fact carried out twice twisting in the match network spun yarn process, spun yarn and common yarn effect are different, its single thread has identical twisting effect with resultant yarn, and the yarn appearance is bright and clean, level and smooth, filoplume is few, though be single thread, the effect of strand is arranged, can partly replace strand, thereby ABRASION RESISTANCE is good.

" particle yarn " claims " knot yarns " again, be a kind of of yarn defect title, on fine spining machine, can utilize " particle yarn device " to produce particle yarn, its spinning principle is: make skin rod horizontal displacement in the fine spining machine, kink is at the medium rubber roller upper leather ring and be enclosed within apron generation afterturn under the middle roller, one special device is arranged on the upper and lower apron, and afterturn makes yarn produce " particle ", and particle size is controlled by the medium rubber roller horizontal displacement.

The shortcoming of above-mentioned three kinds of yarns is: style is single, can not have multiple advantage concurrently, can only be used for common weaving face fabric usually, can't be used for high-grade weaving face fabric.

The utility model content

A technical problem to be solved in the utility model is: provide a kind of unique style various, simultaneously have above-mentioned three kinds of yarns advantage, and can be used for the sirospun spendex core-spun particle yarn of high-grade weaving face fabric.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: sirospun spendex core-spun particle yarn, comprise: the spandex silk, be coated with the yarn fiber layer in the outside of spandex silk, this yarn fiber layer twines twisting at interval by two strands of yarns and forms, and also is arranged at intervals with the particle section of projection on the yarn fiber layer.

The beneficial effects of the utility model are: sirospun spendex core-spun particle yarn described in the utility model has the advantage of Siro-spun yarn, spandex core-spun yarn and particle yarn simultaneously, that is: two rove yarns of (1) Siro-spun yarn can be different fibers, also can be the identical fiber or the fiber of two identical blending rates, the fabric that is made into this yarn is through singly dying a kind of fiber or two kinds of fibers dye with different colors is two, fabric can present a kind of plentiful active style, third dimension is stronger, and appearance is bright and clean, level and smooth, filoplume is few; (2) have good extensibility and nerve; (3) cloth cover point-like third dimension is strong, and style is special, and is personalized strong, can be extensive use of in many grade textiles.

Fig. 1 is the structural representation of sirospun spendex core-spun particle yarn described in the utility model.

Fig. 2 is the production technology schematic diagram of sirospun spendex core-spun particle yarn described in the utility model;

Among Fig. 1 to Fig. 2: 1, spandex silk tube, 2, feeding roller, 4, godet roller, 5, spindle, 6, rear roller, 7, middle roller, 8, front roller, 9, twizzle, 10, cop, 11, particle generator, 12, spindle, 51, the spandex silk, 52, yarn fiber layer, 53, yarn, 54, yarn, 55, the particle section.

The specific embodiment

The utility model will be further described below in conjunction with the drawings and specific embodiments.

As shown in Figure 1, sirospun spendex core-spun particle yarn described in the utility model, comprise: spandex silk 51, be coated with yarn fiber layer 52 in the outside of spandex silk 51, this yarn fiber layer 52 twines twisting at interval by two strands of yarns 53 and 54 and forms, and also is arranged at intervals with the particle section 55 of projection on the yarn fiber layer 52.In actual fabrication, described two strands of yarns 53 can be different fibers with 54, also can be the identical fiber or the fiber of two identical blending rates; Described particle section 55 can be isometrical particle, reducing particle or reducing particle etc.

As shown in Figure 2, the mode of production of described sirospun spendex core-spun particle yarn is: will be respectively two rove on two spindles 5 and 12 keep the same draw zone of the parallel feeding fine spining machine of a determining deviation, carry out drawing-off, earlier through rear roller 6, middle roller 7, and then by two strands of single thread yarns of front roller 8 outputs.In this process, particle generator 11 can make skin rod horizontal displacement (top of middle roller 7) in the fine spining machine, kink produce afterturn at medium rubber roller upper leather ring and following apron (being enclosed within middle roller) moment, one special device is arranged on the upper and lower apron, afterturn makes yarn produce " particle ", and particle size is controlled by the medium rubber roller horizontal displacement.Meanwhile, spandex silk 51 on the spandex silk tube 1 is through feeding roller 2, godet roller 4, feed by front roller 8 jaws again, converge with two strands of single thread yarns 53 and 54 by front roller 8 backs, spandex silk 51 is in the centre, two strands of single thread yarns 53 and 54 finally merge together on both sides, obtain cop 10 behind twizzle 9; Its yarn texture is that spandex silk 51 is distributed in the yarn center, and outer wrapping fiber forms yarn fiber layer 52 in the periphery.Just can obtain sirospun spendex core-spun particle yarn described in the utility model through above-mentioned production technology.

Claims (1)

1. sirospun spendex core-spun particle yarn, comprising: the spandex silk is characterized in that: be coated with the yarn fiber layer in the outside of spandex silk, this yarn fiber layer twines twisting at interval by two strands of yarns and forms, and also is arranged at intervals with the particle section of projection on the yarn fiber layer.
