Author:Shiloh, M; Slinger, RIDate:Mar 1973Two blends of dichloro-isocyanuarate (DCCA) treated wool tops and law pilling polyester fibres were prepared, in the ratio of 80/20 and 60/40 wool/polyester.Read more
Author:Smuts, S; Hunter, LDate:Sep 1977The effect of polyester level, type of polyester and certain finishing procedures as well as certain easy-care finishes on the properties of plain weave fabrics manufactured from wool/polyester intimate blends was examined.Read more
Author:Thierron, WDate:Jun 1985The Dref III friction spinning system also provides a method fir combining staple fibres and elastic filament in once process.Read more
Author:Turpie, DWF; Robinson, GADate:Sep 1978A small quantity of the best grade of pigmented wool available in South Africa, sometimes referred to as "merino black" was processed on the worsted system and converted into fabric.Read more
Author:Strydom, MA; Van der Merwe, JPDate:Sep 1983In part II of this series, work concerned with the processing behavior of sorted karakul in five different trade types was described.Read more
Author:Strydom, MADate:May 1980Five lots of sorted karakul, varying in seed content and mean fibre length, were processed into worsted tops and the raw fibre properties and processing performance recorded.Read more
Author:Thierron, W; Hunter, LDate:Sep 1983Cotton/polyester yarns were spun on a DREF III spinning machine and their properties compared with those of the corresponding yarns spun on ring and rotor machines.Read more
Author:Thierron, WDate:May 1985Polyester/wool yarns were spun successfully on a Dref III friction spinning machine and a ring spinning machine. The Dref II machine provided considerably higher production rates than the ring spinning machine and also involved fewer processing ...Read more
Author:Turpie, DWFDate:Sep 1987The necessity of totally effective carbonising of raw wool and mohair is questioned, and an alternative treatment, employing milder, less effective carbonising conditions supplemented by traditional unsophisticated carding (and perhaps combing) ...Read more
Author:Turpie, DWFDate:Mar 1988The effects of a mild (partial) carbonising treatment on the characteristics of card slivers and slubbings produced on the woollen system of manufacture from various lambs wool lots are reported.Read more
Author:Weideman, EDate:Sep 1976The liquid diiodomethane has been used extensively for measuring contact angles on solids, and he values obtained are used for the calculation of the surface free energy of the solids.Read more
Author:Weideman, E; Van Rensburg, NJJDate:Nov 1976A brief review of the theory and literature on interfacial phenomena is given. A statistical analysis of published data has shown that the value obtained for Y (the surface free energy or surface tension of a solid), is dependent on the values ...Read more
Author:Aldrich, V; Kruger, PJDate:Oct 1972An apparatus is described which simulates the withdrawal action of a rectilinear comb, allowing the measurement of the necessary to withdraw a tuft of fibres from a pin bed at high speed.Read more
Author:Robertson, AD; Van Rensburg, NJJDate:Oct 1973The limiting oxygen index values of cotton fabrics which had been treated with various reagents were determined.Read more
Author:Robertson, AD; Van Rensburg, NJJDate:Oct 1973The limiting oxygen index values of cotton fabrics which had been treated with various reagents were determined.Read more
Author:Aldrich, De VDate:Jan 1975A survey was carried out the characteristics of 24 cotton blends used and 102 carded yarns spun from these blends by 13 South African mills.Read more
Author:McCormick, SG; Van Rensburg, NJJDate:Mar 1977The total amount of methylene chloride extractable matter, the total cyclic trimer content and the surface content of 23 commercial polyester staple and filament samples were determined.Read more
Author:Taylor, H; Veldsman, DPDate:May 1978A study was made of the effects of various machine parameters as well as lubrication on the spinnabilty of all-wool and a 75/25 wool/cotton blend on the schubert and Salzer RU-11 rotor spinning machine.Read more
