Spin, utilize Advance of Compact Spinning Technology to spin, process through large circle machine weaving, dyeing and Final finishing.
Compact spinning is a kind of Advanced Spinning Technologies carrying out spinning on the Novel ring spindle spinning frame improved, at ring spindle yarn
Add a fibre deposition district before machine travel device, essentially eliminate front roller and twist triangle to the spinning between twisting point
District, fiber strip, after front roller nip exports, first passes through abnormity aspiration channel overcoat grid ring, and yarn is attached in grid ring,
Together move with grid ring, due to contraction and the polymerization of air-flow, make strand integrated composite, rotation by the air draught groove of special pipe,
Progressively transferring cylinder to from flat belt-like, the termination of fiber is all twisted in yarn, and therefore resultant yarn is closely, yarn appearance light
Clean, filoplume is few.Due to twisting before ultimate fibre fully stretch, parallel, do not have filoplume to stretch out sliver main body, so resultant yarn filoplume is very
Few, closely, mutual cohesive force is big in ultimate fibre arrangement, this strength also contributing to improve yarn, evenness fault, and thick, details refers to
It is better than traditional yarn to mark.Due to the These characteristics of compact spinning, provide extraordinary condition for next procedure, alleviate starching,
The pressure of the operation such as singe.
Use multiple fiber blend, it is possible to learn from other's strong points to offset one's weaknesses in performance, fully demonstrate the premium properties of various fiber, give
