Description
Technical field
The present invention relates to air injection air vortex spinning line technology field, specially a kind of high-strength wearable jet based on contact hot-rolling
The processing method of vortex spinning yarn.
Background technique
Air-jet eddy-current spinning changes the resultant yarn mode of Air-Jet Spinning, twists free tail end resultant yarn using high speed rotation air-flow, makes
Wrapper fibre quantity is greatly improved compared with Air-Jet Spinning, therefore the long filoplume of 3mm or more is substantially achieved elimination, and product has excellent resist
Hair pilling property.The problem of synthetic yarns product easy pilling can be significantly improved using this advantage.However jet whirlpool
Stream yarn is although strength is greatly improved compared with jet spun yarn, and compared with ring spinning line, strength still only has its 80-85%；Freely
Tail end fiber looping yarn core process is nearly free from inside and outside transfer, causes interfibrous cohesive force inadequate, influences yarn strength
Increase, and wear-resisting process yarn is easy to disintegrate, and influences wear resistance；Furthermore because of the influence of chemical fibre surface finish, yarn
The a large amount of finishes of forming process assemble hollow spindle inlet ambient, and free tail end fiber is caused to be beaten around hollow spindle rotary course
Sliding phenomenon, to form soft twist yarn, this will be so that yarn strength further declines, and the irregular phenomenon of yarn strength is aggravated.
102121146 B of Chinese patent CN " polyester staple fiber for air-jet eddy-current spinning yarn process " is by commonly washing
Profile Polyester Fibre is added in synthetic fibre fiber to reduce the phenomenon that main components oil agent foulant such as vortex tube, spindle is assembled, but
When high-speed spinning, the cord on profiled filament is rubbed can also bring abrasion to aggravate when scraping spindle surface finish to spindle, reduce spindle
Service life.102691143 B of Chinese patent CN " a method of improve air vortex spinning yarn forming performance " the damp and hot softening of segmented
Processing method reduces fiber modulus and rigidity online, improves that fiber is easy to control, easy reel-twist performance, effectively improves air vortex spinning
Yarn forming performance, but this method because synthetic fibers it is mostly non-hygroscopic, to pure synthetic fibers air-jet eddy-current spinning yarn processing have no it is aobvious
Write effect.Chinese patent CN 102787405B " a kind of hollow spindle with spiral-guide slot " is by hollow spindle top
The form of outer surface setting spiral-guide slot of the fiber entry bottom end that extends to middle part make yarn consolidation, uniformity with
Yarn strength improves, but the free tail end fiber of resultant yarn process is around hollow spindle surface high speed rotation, hollow spindle surface guide channel
Presence undoubtedly exacerbate collision and abrasion of the fiber to hollow spindle surface, continual and steady spinning is difficult to realize.By low melting point
Fiber is introduced into air-jet eddy-current yarn product development, and by the online contact hot-rolling of yarn forming process, is realized a kind of high-strength resistance to
Grind the processing of air-jet eddy-current spinning yarn.
To solve the above-mentioned problems, this case is given birth to therefrom.
