PBST/棉包芯纱的拉伸回复性能   总被引:1,自引:0,他引:1  
通过对不同捻度和混纺比的PBST(聚丁二酸-共-对苯二甲酸丁二醇酯)与棉包芯纱拉伸回复性能的分析,探讨了捻度和混纺比对PBST包芯纱回弹性能的影响.在捻度相同、PBST纤维相同的条件下,PBST包芯纱的拉伸弹性回复性随着棉纤维的增加而减少;在纱线混纺比相同时、PBST包芯纱的拉伸弹性回复率随着捻度的增加呈先增后降的趋势.采用捻度为500捻/m和40/60的混纺比纺制PBST/棉包芯纱时,纱线的拉伸弹性回复性能较好,并且在小变形下,PBST包芯纱能保持良好的拉伸回复性.这对PBST包芯纱的开发和应用具有一定的参考价值.  相似文献

Simultaneous dyeing and durable press finishing of cotton fabrics with acid dyes bearing the different molecule structure and durable press finishing agent (DP agent abbr. ) based on modified DMDHEU were investigated by using the pad-dry-cure process. Some factors affecting the process, such as structure of acid dyes, DP agent, catalysts and curing temperature were discussed. The dyed and finished fabrics were evaluated with respect to color strength, fixation, crease recovery angle, breaking strength and fastness properties. The results indicate that structure of acid dyes has a striking effect on the color strength of dyed and finished cotton fabric. The color strength and dry crease recovery angle of dyed and finished cotton fabric increases, whereas breaking strength decreases with increasing concentration of DP agent. It is necessary for ammonium nitrate to serve as catalyst. It is found that relatively satisfactory properties of dyed and finished cotton fabric can be obtained with appropriate adjustment of treating conditions.  相似文献

The effects of pigment glands and gossypol on the somatic cell culture of upland cotton were studied, using the materials as follows: three pairs of glanded and glandless upland cotton near isogenic lines, TM-1, and Coker 312. The results showed that the pigment glands and gossypol contents in the explants had great inhibiting effect on the induction and growth of callus in somatic cell culture of upland cotton, and the induction rate of callus and the single callus weight of glandless cotton were much higher than those of their glanded near isogenic lines. It was easier to obtain regeneration plants from glandless cotton than from their glanded near isogenic lines. There was a significant inverse correlation between the gossypol contents in the explants and callus induction rate, with the correlation coefficient of -0.84. The vitro gossypol in the medium had some inhibiting effect on the induction and growth of callus, especially for the glandless cotton. However, a certain concentration of vitro gossypol in the medium (0.1 mg/L) was an aid to the steadiness growth of callus in glandless cotton somatic cell culture, with a high rate of embryogenic cells which was in favor of plant regeneration, and it was also relatively easy to obtain regeneration plants when they were transferred into differentiation medium with 0.1 mg/L of vitro gossypol, even for some cultivars which are difficult in somatic cell culture. In addition, the gossypol content and its variation in the seedlings and callus during culture of Coker 312 were discussed, as well as the relationship between gossypol variation in the explants and its somatic cell culture. The probability of vitro gossypol used in cotton somatic cell culture for the improvement of somatic cell culture was suggested.  相似文献
