It is observed that only the medium burry wools having up to 6% vegetable matter can be brought to an acceptable level by mechanical removal of vegetable matter on the woollen card.</span> Page(s): 93-94 1983-09-01T00:00:00Z http://nopr.niscpr.res.in/handle/123456789/33079 Title: Extrusion of Waste Polyamides Authors: Sayed-Esfahani, M H 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 and 6.6 were re-extruded into filaments to examine the feasibility of industrial processing of waste nylon. Although some degradation occurred during extrusion, satisfactory re-extrusion of both the nylons could be accomplished. Further re-extrusion caused deterioration in the characteristics of the samples, the deterioration being much more pronounced in the case of nylon 6.6. It follows that nylon 6 (but not nylon 6.6) can be re-extruded to produce good usable textile filaments and if the discoloration problem could be overcome, re-extrusion of nylon 6 could be a practical proposition.</span> Page(s): 89-92 1983-09-01T00:00:00Z http://nopr.niscpr.res.in/handle/123456789/33078 Title: Evaluation of Wool/polypropylene Blends Authors: Kalsy, S; Arora, R K 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 processing behaviour of polypropylene staple fibre and its blends with wool has been studied on worsted set of machinery. Optimum blends of wool with polypropylene of different deniers have been evaluated. On blending with wool, the polypropylene fibre produces a yarn with unique properties suited for knitwear.</span> Page(s): 85-88 1983-09-01T00:00:00Z http://nopr.niscpr.res.in/handle/123456789/33077 Title: New Azodisperse Dyes with 5-Pyrazolone Ring for Dyeing Polyester Fibres Authors: Fadda, A A; Metwally, M A; Khalil, A M 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 dyeing performance of some4-arylhydrazono-1-hydroxymethyl-3-methyl-2-pyrazolin-5-ones on polyester fibres has. It is observed that these dyes have good affinity for polyester fibres, whereas polyamide and triacetate fibres are only slightly stained. The maximum exhaustion of the dye bath takes place at 100°C after 90 min. The fastness properties of the dyes on polyester fibres are compared with respect to the position and the nature of the substituent.</span> Page(s): 82-84 1983-09-01T00:00:00Z
