Stresses at 2 and 30% extension and the Hookean slope differ significantly in groups and breeds, whereas stresses at 15% extension and breaking stress differ significantly among the diameter groups. There is no significant effect of breeds and groups on breaking extension.</span> Page(s): 133-135 1982-12-01T00:00:00Z http://nopr.niscpr.res.in/handle/123456789/33149 Title: Production and Characterization of Nylon-6 Filaments Containing Carbon Black Authors: Datye, K V; Mishra, S; Gupta, V B Abstract: <span style="font-size:11.0pt;line-height:115%; font-family:" calibri","sans-serif";mso-ascii-theme-font:minor-latin;mso-fareast-font-family:="" "times="" new="" roman";mso-fareast-theme-font:minor-fareast;mso-hansi-theme-font:="" minor-latin;mso-bidi-font-family:"times="" roman";mso-ansi-language:en-us;="" mso-fareast-language:en-us;mso-bidi-language:ar-sa"="">Nylon-6 filament yarns containing up to 1.5% carbon black have been prepared using two different methods, viz. (1) incorporating carbon black in disperse form during polymerization and melt spinning, and (2) blending the chips containing 1.5% carbon black, prepared as in (1), with chips without any carbon black (blank) and melt spinning. The filaments thus produced were examined for their structure and properties. It has been observed that the samples prepared by method (1) are more homogeneous and have more uniform properties.</span> Page(s): 126-132 1982-12-01T00:00:00Z http://nopr.niscpr.res.in/handle/123456789/33148 Title: Effect of Preparatory Process Parameters and Machine Conditions on Weaving Performance Authors: Sharma, I C; Kaushik, R C D Abstract: <span style="font-size:11.0pt;line-height:115%; font-family:" calibri","sans-serif";mso-ascii-theme-font:minor-latin;mso-fareast-font-family:="" "times="" new="" roman";mso-fareast-theme-font:minor-fareast;mso-hansi-theme-font:="" minor-latin;mso-bidi-font-family:"times="" roman";mso-ansi-language:en-us;="" mso-fareast-language:en-us;mso-bidi-language:ar-sa"="">The Barbar Colman (BC) high speed spooler and the BC high speed warping machine have been compared with the Rotoconer winding machine and the Cimmco high speed warping machine respectively in respect of their effect on weaving performance by carrying out large scale mill trials. The BC spooler shows better weaving performance than the Rotoconer winding machine due to the higher clearing efficiency of BC snick plates. The type of warping machine does not influence the weaving performance.</span> Page(s): 121-125 1982-12-01T00:00:00Z
