Spinning of backset of website of Chinese spin economy is to use pipe of spinning of fixed immobile backset, will replace cup of spinning of high speed revolving to have method of a kind of of spinning new-style spinning. In some sense, eddy current spinning just is the air current spinning on real significance. Fiber feed by Luo La giving cotton, become ultimate fibre through pricking roller to open a pine, borrow the action of air current, feed eddy current from high speed of conduit is defeated by cotton inside the canal. Eddy current canal is in charge of the canal outside mixing by core two parts composition. Be in charge of outside go up to have 3 tangential air inlet, the lower end and air-blower are linked together, fan ceaselessly from inside the canal draw-out air, the air edge air inlet outside enters eddy current inside the canal, generate gyrate air stream. When rotating to arrive at core to be in charge of to the air current that go up, the fiber that enters with conduit is defeated by cotton is confluent, along eddy current tubal wall forms link of an agglomeration fiber, be in charge of axes steadily around eddy current, high speed circumgyrate, become fiber twisting gauze. Gauze from guide in gauze aperture continuous by derivative Luo La derivative winding becomes a tube. The characteristic with eddy current the mainest spinning is leave out component of spinning of high speed revolving. The rotational and inertial problem that because used air current twisting to cast off component of high speed twisting,poses and bearing bear problem (be like air current spinning spin a cup of) , still have the problem that increased spinning pulling force because of the balloon that spinning forms () of spinning of the ingot that be like annulus. Eddy current spinning and other and new-style spinning have the advantage of a few respects quite:
Speed fast, yield is high
Speed of spinning of eddy current spinning machine is 100_200m/min, economic rate is in commonly 100_160m/min. Home is spun with eddy current spinning machine make 6_12 flower raise gauze, spinning speed is 100_140m/min, 1000 ingot of 600_800(kg/ of per unit area yield •h) , the 4_5 that is equivalent to annulus ingot gauze times; If spin 40 fair raise acrylic fibbers gauze, use 10 (192 / stage) PF-1 backset spinning machine, crop amounts to 400kg/h. Be equivalent to 20 (4000) the crop of spinning machine of BD-200 air current, be equivalent to spinning machine of 40 annulus ingot the crop of 16320 ingot. A backset spins the crop of thrum, be equivalent to the crop of head of spinning of 2.08 air current or 8.5 annulus ingot. Because eddy current spinning is support backset twisting, if continue to consider to improve, spinning speed still can continue to rise.
Technological process is short, make rate is high
Eddy current spinning is to use fiber a brief informal note to be spun directly make cheese, resemble other and new-style spinning so same, but leave out roving and canister of subsidiary channels in the human body through which vital energy two working procedure. Because rate of broken end of eddy current spinning is very low, the loss that answer a flower is little, make rate be as high as 99% above.
