Description
Technical field
The invention belongs to spinninging technical field, relate to a kind of fancy yarn and spinning method for genuine thereof, particularly relate to one and use the revolving cup that cracks, there are two vacuum cavities, the Revolving cup spinning fancy yarn of the spinning device spinning that feeding system is controlled by motor transmission.
Background technology
Revolving cup spinning belongs to open-end-spinning field, has that spinning speed is high, package capacity is big, spin ability is preferable and double can spin the feature of excellent low raw material, it has also become in Advanced Spinning Technologies, technology is the most ripe, application surface the most extensively, spinning form that economy is higher.
Revolving cup spinning the most only uses the leftover bits and pieces of the raw material of low cost, such as textile mills or recycling textile material etc..In 20 century 70 mid-terms, Revolving cup spinning is only applied to spin cotton product, and mainly to spin 97.2tex (6S)、83.3tex(7S) Quality Pure Cotton Yarn Production is main, industry generally believed that Revolving cup spinning was only suitable for thick special Quality Pure Cotton Yarn Production the most at that time.But along with the progress of Revolving cup spinning technology, the spinning suiting scope of Revolving cup spinning is also being gradually increased.Nowadays, Revolving cup spinning can be not only used for the production of high-grade knitted yarn, applies also for all fancy yarns such as undertwisted yarn, slub, S twist yarn, covering yarn.
Utilize Revolving cup spinning to produce the fancy yarn kinds such as slub and there is multiple method, substantially can have following several scheme: (1) changes feed roller speed；(2) delivery roller speed is changed；(3) change feed roller and delivery roller speed simultaneously；(4) appropriate location at defeated fine passage or combing roller adds additional feeding fiber mechanism；(5) damping point is set in revolving cup；(6) cutting in revolving cup；(7) transformation of navel.
Change feed roller speed or the method for delivery roller speed, the shortest fancy yarn that can spin a revolving cup perimeter length slubbing, and the length of slubbing and diameter is utilized to be affected bigger by revolving cup diameter and motor performance；Arrange in revolving cup damping point method be arrange in fibre deposition groove in revolving cup 1 or several damping point spin fancy yarn, although using the method can spin out the fancy yarn that thickness joint is shorter, but fibre deposition groove particularly damps the easy dust stratification in a both sides, make the thickness joint instability of fancy yarn；In revolving cup, the method for cutting is artificially to process groove on fiber slippage face so that it is have certain degree of depth and length, but this method produces dust stratification in making groove equally, affects the stability of fancy yarn.
Summary of the invention
Problem to be solved by this invention is to provide a kind of fancy yarn and spinning method for genuine thereof, specifically one and uses the revolving cup that cracks, has two vacuum cavities, the Revolving cup spinning fancy yarn of the spinning device spinning that feeding system is controlled by motor transmission.
A kind of spinning method for genuine of the fancy yarn of the present invention, the spinning device spinning the employing of described fancy yarn includes feed roller, combing roller, defeated fine passage, navel, revolving cup, doffing tube, sealing ring and motor, described revolving cup includes cup and cup axle, cup is made up of at the bottom of cup and cup edge, described cup is along being crossed to form collection surface at the bottom of cup, also include revolving cup case, revolving cup base, and first exhaust tube and the second exhaust tube, outside described revolving cup case is placed at the bottom of described cup, and outer ledge at the bottom of edge of opening and described cup surrounds formation the first negative pressure cavity, the distance of outer ledge at the bottom of described revolving cup case edge of opening and described cup is that described revolving cup just can the distance of normal rotation；Described revolving cup is arranged in described revolving cup base, and described revolving cup base surrounds formation the second negative pressure cavity with described turn along outside and described sealing ring, described first exhaust tube is connected with described first negative pressure cavity, provides from the cup underflow negative-pressure air-flow to rim of a cup direction for described revolving cup；Described second exhaust tube is connected with described second negative pressure cavity, provides from the cup underflow negative-pressure air-flow to rim of a cup direction for described revolving cup；Described revolving cup has the narrow slit at the bottom of through revolving cup cup, and described feed roller passes through motor transmission, and described motor passes through a Controlled by Programmable Controller transmission.
As preferred technical scheme:
