Abstract
The utility model discloses a cotton bale polyester filament core-spun sewing thread with high intensity and low shrink, belonging to the technical field of textile technology and aiming at solving the problem of the low fusion point and the low mightiness of a high-speed sewing thread. The cotton bale polyester filament core-spun sewing thread of a high intensity and low shrink type is a core-spun high-speed sewing thread which comprises more than two cotton fibre twisting yarns with outer enclosing layers and inner enclosing fluidization fibre filament cores. The utility model has novel structure and innovated design and is suitable for high-speed sewing machines of various types.
Description
Technical field
The utility model belongs to the used high speed sewing thread of a kind of high speed sewing machine in the textile technology field.
Technical background
Along with advancing by leaps and bounds and the raising day by day of labor productivity of science and technology, make the high speed sewing machine large-scale popularization of needle trade use, because the friction between suture needle and fabric when sewing at a high speed produces a large amount of heats in suture needle; Therefore increase (as the shirt neck etc.) when the fabric layers that will sew, the temperature of suture needle will sharply raise, and especially sewing velocity is in that 5000 pins/when min was above, the suture needle meeting was above 300 ℃; Also just higher specification requirement has been proposed the high speed sewing thread.In known technology, the used high speed sewing thread of existing high speed sewing mainly is made up of 2～several strands polyester filament twisteds, and the fusion point of high-tenacity polyester filament only is 255 ℃-260 ℃, so when the high speed sewing operation, easily fuse, influence operation, and powerful low, easily balling-up, and seamability is relatively poor, also makes troubles to use.
Summary of the invention
In order to overcome the deficiency of prior art, solve the existing problem that high speed sewing thread fusion point is low, intensity is low.The purpose of the utility model provides a kind of novel structure, design innovation, fusion point height, twist height, intensity height, be difficult for fusing, adapt to the needs of high speed sewing machine, the requirement of raising labour productivity, outward appearance is bright and clean, the yarn defect is few, the powerful coefficient of variation is few, and seamability is better, new pattern high speed sewing thread easy to use.
The technical scheme in the invention for solving the above technical problem is:
A kind of high strength, low shrinkage type bale of cotton polyester filament core-spun sewing thread, the bag core high speed sewing thread that it is made up of the fine long filament inner core of bag fluidization twisted thigh in 2～several strands cotton fiber surrounding layers.
Above-mentioned high strength, low shrinkage type bale of cotton polyester filament core-spun sewing thread, described this sewing thread preferably adopts the bag core high speed sewing thread of being made up of 2～6 strands of cotton fiber surrounding layer Nei Baolian polyester filament inner core twisted thighs.
Above-mentioned high strength, low shrinkage type bale of cotton polyester filament core-spun sewing thread, described chemical-fibres filaments inner core or adopt the high-strength chemical-fibre long filament of other suitable type intensity 〉=8.0g/d, core yarn dry-hot shrinkage≤2.5%.
Use of the present utility model is identical with existing high speed sewing thread.
Because technique scheme has been adopted in the utility model design, has effectively solved the problem that existing high speed sewing thread fusion point is low, intensity is low.Also use the result to show that it compared with prior art has novel structure through test for several times, design innovation, fusion point height, twist height, intensity height are difficult for fusing, adapt to the needs of high speed sewing machine, the requirement of raising labour productivity, outward appearance is bright and clean, and the yarn defect is few, and the powerful coefficient of variation is few, and seamability is better, advantage such as easy to use is applicable to various high speed sewing machine, has practicality and broad prospect for its application.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the concrete structure sketch of the utility model embodiment.
Fig. 2 is the structure for amplifying sketch of cotton fiber surrounding layer Nei Baolian polyester filament inner core single cord among Fig. 1 embodiment.
Each label is in the accompanying drawing: 1 cotton fiber surrounding layer; 2 polyester filament inner cores.
The specific embodiment
As accompanying drawing 1, embodiment illustrated in fig. 2, the bag core high speed sewing thread that the utility model is made up of 3 strands of cotton fiber surrounding layers, 1 Nei Baolian polyester filament inner core, 2 twisted thighs.
The utility model high strength, the low preparation method one embodiment that shrinks bale of cotton polyester filament core-spun sewing thread are:
1, select materials: the polyester filament inner core is selected the high strength of intensity 〉=8.0g/d, core yarn dry-hot shrinkage≤2.5%, low contraction terylene long filament for use.The cotton fiber surrounding layer is selected the high-quality long-staple cotton of fibre length 〉=35mm for use.
2, process route: long-staple cotton passes through blowing, comb and parallel cotton fibers prior to spinning, combing, twice drafting, makes the rove bar by Speed frames, feeds fine spining machine again and carries out normal drawing-off.Additional unwinding device, tenslator and positioning guide wire device on high strength, the transformed fine spining machine of low contraction terylene long filament process are around accurate feeding fine spining machine front roller, long-staple cotton rove yarn with drawing-off meets at fine spining machine front roller nip place, after front roller output, cross twizzle, under rings steel traveler twisting winding, form cladded yarn.After the cladded yarn cop added heat setting, through fully-automatic spooling machine, high speed doubling winder, double twisting operation, finished product added HEAT SETTING once more, produces product line.
3, technological process: long-staple cotton → A002D garden dish bale plucker → A03 mixing and blowing machine → A036C porcupine opener → A092A hopper → A076D single beater scutcher → A186D carding machine → A201D combing machine → FA306 drawing frame → FA306 drawing frame → A454E Speed frames → A513W fine spining machine (high strength, low contraction terylene long filament import) → yarn steaming pot → No.21C bobbin winder → PS6-D doubling winder → VTS-09 two-for-one twister → yarn steaming pot → finished product.
Claims (2)
1, a kind of high strength, low shrinkage type bale of cotton polyester filament core-spun sewing thread, it is made up of 2～several strands polyester filament twisteds, it is characterized in that the bag core high speed sewing thread that this sewing thread is made up of 2～several strands cotton fiber surrounding layers (1) Nei Baolian polyester filament inner cores (2) twisted thigh.
2, high strength according to claim 1, low shrinkage type bale of cotton polyester filament core-spun sewing thread is characterized in that the bag core high speed sewing thread that this sewing thread is made up of 2～6 strands of cotton fiber surrounding layers (1) Nei Baolian polyester filament inner cores (2) twisted thigh.
