Experimental Investigation of Yarn Twist Blockage

In twisting a yarn running over a guide surface, the twist inserted into the part in front of the guide is impeded to transmit freely to the part behind the contact zone. A new device has been set up for investigating twist blockage and yarn torque - twist simultaneously. Measurements of twist blockage in relationship to different parameters have been carried out by using a monofilament yarn and a multifilament yarn. The factors under consideration include the wrap angle, yarn tension and input twist.

Pulsed UV Laser Modification of Polyester Textile Materials:Effect on Wettability

There has recently been great interest in ablative photodecomposition(APD), notably in pulsed UV laser treatment on polymers, for modification of physical and chemical properties, such as dyeability, printability, adhesion, Iuster and many more. Very little attention was focused, however, on the property of wetting behaviour,which is one of the most fundamental properties in affecting polymer science. Poly(ethylene terephthalate) (PET) fibers drawn to two different draw ratios and under two temperatures, and three white knitted polyester fabrics made of 100% PET fibre were used to investigate their wetting behaviour due to excimer laser treatment.Experiments like water contact angle measurement, vertical drop test and moisture regain were conducted upon samples and all results give the same conclusion that laser treatment increases the hydrophobicity of all samples tested. Scanning electron microscope (SEM) observation reveals how the morphological modification of polymers by laser treatment is correlate     

1A6/DRIM,the human UTP20 functions in 28S and 5.8S rRNA processing

1A6/DRIM has been identified as UTP20, a small subunit processome component, functioning in 18S rRNA processing. In the present study, the maturation of 28S rRNA and 5.8S rRNA was inhibited when 1A6/DRIM was silenced in HeLa cells; and coin-cidently, an accumulation of 32S rRNA precursor was observed. Immunoprecipitation was performed with the anti-1A6/DRIM antibody, followed by Northern blot with the ITS2 probe. The results showed that 1A6/DRIM was associated with both 32S and 12S rRNA precursors in vivo. The expression profile of 1A6/DRIM during rRNA processing was investigated by sucrose density gradient fractionation in combination with Western blot analysis. The results demonstrated that 1A6/DRIM was involved in the pre-60S particles in addition to the pre-40S particles and co-sediment with the 32S and 12S rRNA precursors in the nucleolus. Furthermore, the interaction of U8 snoRNA with 1A6/DRIM was revealed by immunoprecipitation. These results demonstrated that 1A6/DRIM interacted with both 32S rRNA and U8 snoRNA, being involved in 28S rRNA and 5.8S rRNA processing.

Tensile property of Pneumatic spliced Short-staple Ring Spun Yarns

The tensile property of the spliced yarn splice under different splicing conditions has been investigated. The retained spliced strength of the splice spliced under different splicing conditions was obtained as the indicator for the performance of the splicer under that particular splicing condition. The results showed that, the length of the yarn tails and the yarn linear density are the parameters that has the most important effect to the tensile property of the spliced yarn.
