Description
Technical field
The present invention relates to spinninging technical field more particularly to a kind of production methods of high-strength and high-modulus vortex spinning sewing thread.
Background technology
Currently on the market, the production of sewing thread is mainly obtained by doubling technique into producing after strand by ring spinning yarn,
Its process is more, flow is cumbersome, the amount of labour used is big, and cost is big and inefficient.Therefore, in order to improve the production status of sewing thread,
There is spinning scientific worker to develop sewing thread production yarn, and sewing thread is made using doubling technique using vortex spinning, but
The problems such as finding to generate retraction, clothes is made to splice out-of-flatness in the use of this sewing thread.
Publication No. CN107059198A Chinese patents disclose " a kind of production method of sewing thread production yarn ", packet
Cotton cleaning process, carding step, mixing in doubling step and vortex spinning process are included, i.e., by raw material shredding, removal of impurities, is uniformly mixed, passes through cotton carding
Process obtains the fiber carded sliver, then by three draftings, fiber is carried out and is closed, drawing-off, makes straightening of fibers parallel, obtains fiber
Yarn finally by vortex spinning process, makes long fibre gather to the center of yarn using the vortex of air, and staple fiber outer layers
Cladding, the special construction of yarn body makes it that can reach the strength of RING SPINNING strand as long as single thread, while has the filoplume few, bright and clean etc.
Feature.The strength that the method makes the strength of its single thread reach RING SPINNING strand using spinning technique production yarn is vortexed, but by simultaneously
During being used after line and doubling twisting formation strand as sewing thread, the special construction of yarn makes its generate retraction, uncomfortable
Cooperate the splicing for clothes for sewing thread.
Invention content
The technical issues of solution：For the existing production technology process for spinning sewing thread is more, flow is cumbersome, the amount of labour used is big,
The shortcomings of cost is big and inefficient, line easily bounces back in use, the present invention provide a kind of high-strength and high-modulus vortex spinning sewing
The production method of line, the production method process is few, yield is big, recruitment is few, and the sewing thread produced has strongly big, wearability
