The water flux of pan / pu hollow fiber membranes increased with the increase of draw ratio and concentration of pan Pan pu中空纖維膜的的水通量隨著拉伸倍數(shù)的增大而增大,隨著pan含量的增大而增大。
The results indicate that : ( 1 ) as the drawing ratio increase , the mechanical properties , crystallinity and orientation of uhmwpe fiber all increase greatly , while the average crystal size decreases 結(jié)果表明:隨拉伸的進(jìn)行, uhm筋胭e纖維的力學(xué)性能、結(jié)晶度、取向度均大大提高,而晶粒尺寸逐漸變小。
While polyester fiber is subject to different draw ratio and heating temperature during high speed spin - fling , its original molecular orientation and crystallinity of polyester fiber are changed 摘要聚酯在高速紡絲過程中,施以不同的拉伸倍數(shù)與溫度,會(huì)造成纖維結(jié)晶度與取向度的變化,從而影響纖維的物理性能。
Polyester petg sheet has outstanding thermoforming properties , combining low energy consumption , short production cycles , extreme draw ratios and good mould reproduction without the need for pre - drying 公司愿以先進(jìn)的技術(shù),可靠的質(zhì)量保證和真誠的合作態(tài)度為客戶提供最優(yōu)最滿意的服務(wù),我們真誠地期待您的惠顧。
This paper investigated the physical properties of polyester filament yarn such as tenacity , elongation and boiled water shrinkage by means of analyzing the poy which had been treated by different draw ratio and heating temperature 通過對不同拉伸倍數(shù)及不同溫度處理的poy的分析,探討長絲紗的強(qiáng)度、伸長度及沸水收縮率等物理機(jī)械性質(zhì)。
