紡絲拉伸工藝 的英文怎麼說
中文拼音 [bǎngsīlāshēngōngyì]
紡絲拉伸工藝
英文
draw-spinning process-
On the other hand, the collection on a rotating cylinder is helpful to the process of electrospinning, and it is furthersome to get the ordered mats, otherwise, because the velocity of cylinder rotating is far less than that of nanofiber depositing, the rotation of cylinder has not the function of drawing
另外，採用輥筒收集有利於紡絲工藝的順利進行，而且輥筒收集能使纖維氈中的纖維較整齊排列，但輥筒的卷繞速度遠遠小於電紡絲速度，輥筒的旋轉不能起到拉伸的作用。Pdlla / ha composite fibers were produced by melt spinning, and the choices of the process parameters such as temperature, revolving speed and drawing speed etc were discussed
選用熔融紡絲法制備pdlla ha復合纖維，探索了熔融紡絲過程中溫度、擠出機轉速、拉伸速率、加料速度和冷卻速率等一系列工藝參數的選擇及其影響因素。" it ' s all polypropylene. but by changing the manufacturing conditions - like the extrusion temperature, the weaving speed, the stretching tension, you can optimize the thread production.
這些都是聚丙稀，但是通過改變製造工藝，例如排出的溫度，紡織速度，拉伸張力，你能夠最優化絲線的生產。By optimizing and controlling the technology conditions of grey yam linear density, spinning speed, stretching temperature, stretching ratio, tension - setting and shrink - setting, the polyester staple with shrinkage rate over 20 % was successfully developed with normal polyester chip
通過對原絲線密度、紡絲速度、拉伸溫度、拉伸倍率、緊張熱定型及鬆弛熱定型等工藝條件的優化和控制，採用常規聚酯切片成功開發出收縮率在20 %以上的滌綸短纖維。The modulus and strength of pet / mmt fiber were lower than those of pure pet fiber. this is probably because the lamellar montmorillonite does not disperse randomly and completely, and besides, the spinning and drawing process in our research is limited to make the montmorillonite layers better oriented along the fiber
但pet mmt復合纖維的模量及斷裂強度比純pet纖維稍有下降，這是因為在pet mmt復合材料中蒙脫土片層還沒有達到理想的無規分散，存在一定的團聚及未完全剝離現象，此外現有的紡絲拉伸工藝還不能使蒙脫土片層在纖維縱向形成很好的取向。分享友人
