Description
Technical field
The invention belongs to the air-jet eddy-current spinning field, particularly relate to a kind of air-jet eddy-current spinning self-twisting hollow ingot.
Background technology
Air-jet eddy-current spinning becomes present development one of novel spinning technology faster with its high yield excellent properties at a high speed, but still there is certain problem in yarn qualities so far, show that mainly the yarn details is many, powerful low, thereby limited the expansion of its product development Application Areas.Its main cause is: one, from processing method, owing to adopt swirling eddy twisting mode, though efficient has improved greatly with respect to machinery twisting, the decline of fiber control is caused the loss of fiber again easily, thereby make the final yarns details increase and powerful decline; Two, from yarn texture, because the air-jet eddy-current spinning final yarns is that middle parallel fibers adds outer covered fiber, compare with the helical structure of fiber in the ring spinning line, the fibre cohesion of air-jet eddy-current spinning yarn is low, thereby makes yarn strength descend to some extent.Therefore how to optimize yarn texture, improve many, the powerful low problems of details, become and broken through the important topic that air-jet eddy-current spinning further develops bottleneck; Simultaneously, though air-jet eddy-current spinning utilizes air-flow twisted fibers resultant yarn to overcome the big shortcoming of inertia force that twisting parts high speed rotary produces, not only can improve twisting efficiency greatly, and can significantly improve spinning speed and cut down the consumption of energy, but air-flow is strong to the control of fiber not as machinery to the control of fiber, under action of high-speed airflow, the part fiber will break away from the control of air-flow, discharge with air-flow, form the fibre that falls, cause utilization ratio of raw materials to reduce greatly, thereby increase the yarn production cost.
Summary of the invention
Technical problem to be solved by this invention provides a kind of self-twisting hollow ingot special for jet air vortex spinning, to solve the defective that yarn texture is relatively poor in the prior art, details is many, brute force is low.
A kind of self-twisting hollow ingot special for jet air vortex spinning comprises fiber entry (1) and hollow ingot passage (2), has surface grooves (3) on described fiber entry (1) and the hollow ingot passage (2), the diameter D of fiber entry (1)

2Be 1.2～1.6mm, the width D of surface grooves (3)
3Be 0.1～0.8mm, fiber entry (1) is to the height H of hollow ingot passage (2)

2Be 4～6mm, surface grooves (3) height H
3Be 0.1～1mm.
Beneficial effect
The diameter of fiber entry of the present invention helps entering of fiber greater than the diameter of hollow ingot passage, and the frictional force effect of inlet surface groove, help to resist the withdrawing power of air-flow, reduce the loss amount of fiber, can improve utilization ratio of raw materials, thereby reduce the yarn production cost; Simultaneously when continuous fibre stream enters hollow ingot because the frictional force effect of surface grooves, fiber self will produce certain rotation under swirling eddy drives, and will keep this rotation status to enter the yarn body, by the twist of yarn itself its state is fixed at last, on the one hand because fiber itself reverses the effect of internal stress, cohesive force in the yarn between the fiber will strengthen greatly, thereby improve the brute force of final yarns; The streamlined structure of surface grooves inner surface can prevent that fiber is wounded.
