Line.
It is described that two retwist silks, two elastic force monofilament are mutually kinked and refer to for primary filaments line：Two retwist silk bobbins
Simultaneously on bobbin cradle, two elastic force monofilament bobbins simultaneously on another bobbin cradle, two compound-twist silk threads respectively by
One group of godet roller is drawn, then simultaneously by guide porcelain road to obtain and close compound-twist silk thread, meanwhile, two elastic force monofilament are respectively by one group
Godet roller is drawn, then simultaneously by guide porcelain road to obtain and close elastic force monofilament, then, and is closed compound-twist silk thread and closed elastic force list
Simultaneously by a pair of of front roller on doubling frame, front roller clamping exports silk, and last spindle rotation twisting winding completes processing, with
Two retwist silks, two elastic force monofilament are mutually kinked as primary filaments line；Guide porcelain road is hollow circular cone structure,
The input terminal width in guide porcelain road is more than the output end width in guide porcelain road.
The acquisition retwist silk refers to：First by selected FDY filament by boundling and wire process is to obtain non-twist multifilament, then
The twist that non-twist multifilament is increased to 4T/10cm -20T/10cm by twisted filament process, to obtain retwist silk；The FDY long
The fracture strength of silk is 5.2 cN/dtex -12.0 cN/dtex, and elongation at break is 7% -23%.
The acquisition elastic force monofilament refers to：Selected elongation at break is 300% -600%, and elastic recovery rate is 85% -95%
Elastic polyurethane fiber monofilament or PVC elastic force monofilament.
The principle of the present invention is described as follows：
FDY filament：Refer to FDY（FULLY DRAWN YARN）Fully drawn yarn introduces stretching action in spinning process, can obtain
Obtain the undrawn yarn with high-orientation and crystalline medium degree, as fully drawn yarn.
The diameter of retwist silk is the 75% -125% of elastic force filament diameter：Optimal selection is the diameter of retwist silk, elastic force monofilament
Unanimously, such most convenient is manufactured.Because when processing, it is consistent with two root unit body feeding speed of thickness, when twisting,
Two root unit bodies generate identical twist contraction, and the structure of two root unit body loopings arranged side by side is just stablized, just suitable for sewing thread in the present invention
Actual fabrication and large-scale production.
Four section chief's silk threads in the present invention, referring to Fig. 1 and Fig. 2, when in an axial direction by force-extension, retwist silk due to
Its resilience is relatively poor, is not likely to produce deformation, tightens under the effect of external force, forms sandwich layer yarn, and elastic force monofilament then can be by
The retwist silk stretched squeezes and buckling, forms yarn helix and is wrapped in outside retwist silk, forms fasciated yarn.Assuming that the width of single thread
（Diameter）For D, before stretching, the width of four section chief's silk threads does not consider the compression of tow, is 2.41D, when four section chief's silk threads are drawn
After stretching, four section chief's silk threads are changed into looping structure by parallel construction, draw close to form yarn core among two strands of retwist silks, two strands of elastic force lists
Silk translates into looping structure, at this point, the width of four section chief's silk threads becomes 2.73D, i.e. four section chief's silk threads produce drawn expanded
Property.Four section chief's silk threads obtained through the invention have the characteristics that adapt to sew and suture at a high speed secured：On the one hand, in sewing,
Since sewing cable architecture is uniformly without filoplume, it is conducive to puncture suture, meanwhile, have high intensity, the retwist silk of high rigidity feature undertakes
The effect of stitch tension is suitble to high speed sewing processing；On the other hand, the product of suture, stretches under external force, has Gao Rou
Property, high resiliency feature elastic force monofilament will produce winding effect, sewing thread generates lateral expansion because of stretching, and prevents sewing
The sliding of line.
Boundling and wire process：Non-twist multifilament is prepared by boundling and wire process, boundling is designed by fineness, to ensure tow
Line density, monofilament tension want uniformity, in favor of the progress of subsequent handling.
Winding procedure：That is reeling process.This process changes package, increases the Rong Siliang of tow package, improves later process
Productivity.When operation, tow is checked using yarn cleaning device, removes fault influential on quality and impurity on tow,
Improve the uniformity and finish of tow.
High-temperature shaping process：Under certain temperature and damp condition, no-station pole canopy heat treatment is carried out to primary filaments line, is eliminated
The internal stress that primary filaments line is generated by twisting stablizes the twist of primary filaments line, the twist contraction shadow for avoiding primary filaments line from generating
Ring sewed product presentation quality.
Guide porcelain road：Referring to Fig. 3 and Fig. 4, the main function in guide porcelain road is that two components smoothly and are combined, from
And ensure the smooth production of the subsequent four section chief's silk threads for having drawn expanded performance.
