The Polyester Hollow Fibers Reconstructing Technics Is Studied For Sake Of The Item That Makes The 15kt/a Polyester Staple Line

In this master paper, the polyester hollow fibers reconstructing technics is studied that is for sake of the item that makes the 15kt/a polyester staple line of Yizheng Chemical Fiber Co. Ltd have the capacity of producting both normal polyester staple and polyester three-dimension crimp hollow fibers. The paper expatiates the necessity of reconstruction and the technics of hollow fibers firstly; the pivot of the paper is the feasibility and the content of reconstruction. The main factors are concentrated as following:1. spinning temperature2. spinning speed3.melt distribution and computation4. the cylindrical-cooling process parameters5.the draw technics6.the capacity of crimp7. the capacity of cut off8. heat setting without giving stress 9.the systems of oil10.the bale machine11 .the test machineFinally, the paper think that the item of 15kt/a polyester staple line hollow fibers reconstructing is feasible. After reconstruction, the three-dimension crimp hollow fibers of the line accord the require of design. The practice proves that the item is successful.
