THE SCROOPING TREATMENT OF POLYESTER SILKLIKE FIBERS

In this paper the mechanism producing scrooping sound has been discussedtheoretically.It has been recognized that the continuous stick-slip vibrationhaving a certain period and the bigger △E(△E——enery released by stick-slipvibration at one time)are the requisite and surfficient conditions producingscrooping sound.For fiber sample,its surface properties and internal structureare two principal factors influencing scrooping sound.

In this paper the mechanism producing scrooping sound has been discussed theoretically. It has been recognized that the continuous stick- slip vibration having a certain period and the bigger △E (△E-enery released by stick -slip vibration at one time) are the requisite and surfficient conditions producing scrooping sound. For fiber sample, its surface properties and internal structure are two principal factors influencing scrooping sound. Considering the surface properties of polyester fiber after scrooping treatment are the synthetic reflection of the properties used treatment reagents and the surface properties of the fiber, how selecting proper reagents for scrooping treatment would be the key factor influencing the scrooping effect. Some treatment solutions having better scrooping effect have been obtained in the paper. In order to cause better scrooping effect, not only the treatment reagent and surface properties of the fiber, but also the internal structure of the fiber must be considered, It has been shown in practice that the finer irregular CDPET fibers with lower initial modulus have better scrooping effect by means of proper reagent treatment and taking right technology measures.
