Core-spinning of wool with textured filaments,a preliminary report

Author: Kruger, PJ Date: Jul 1971 Core spinning was carried out using wool and 20 denier textured multi-filament nylon. Read more
Preliminary report on a possible method of manufacturing knitted fabrics from wool rich blends

Author: Wolfaardt, C ; Buys, JG Date: Aug 1971 A technique for manufacturing double-jersey fabrics containing low percentages of a synthetic component, is proposed. Read more
Shrink-resist treatment of wool fabrics with an alkylated methylolmelamine resin

Author: Hanekom, EC ; de Mattos, GWP ; Freyer, DB Date: Sep 1971 This investigation was undertaken to establish whether wool fabrics could effectively be rendered shrink-resistant by the application of an alkylated methylomelamine resin without harshening the handle of the fabrics to any significant extent. Read more
Dyeing of wool with reactive dyes from a charged solvent system

Author: Van Rooyen, A. ; Van der Merwe, JP Date: Sep 1971 A method of dyeing wool with reactive dyes from a charged perchlorethylene solution is described. Read more
The bleaching of wool with hydrogen peroxide in the presence of a phosphonic acid as stabilising agent

Author: Van Rensburg, NJJ Date: Sep 1971 Wool can be bleached successfully with hydrogen peroxide in the presence of an organic phosphate acid derivative. Read more
Comparison of the carding performance of fillet and metallic clothing

Author: Turpie, DWF ; Geldard, A ; Kruger, PJ Date: Nov 1971 The single swift metallic card gave results which favored its use in preference to the double swift fillet or double swift metallic cads for a long wool of 64's quality which was free to nearly free of vegetable matter. Read more
A study of lubrication of mohair Part 1: The frictional properties of mohair/wool blend yarns

Author: Hunter, L ; Kruger, PJ Date: Jan 1972 The frictional properties of yarns containing different percentages of mohair were investigated. Read more
Mechanical properties of a resin treated wool/cotton blend fabric

Author: Shiloh, M ; Hanekom, EC ; Slinger, RI Date: Feb 1972 Fabrics having widely differing physical properties can be obtained by intimately blending fibres having disparate mechanical properties. Read more
The design and physical properties of co-we-nit men's outerwear fabrics

Author: Layton, L ; Ellis, R ; Robinson, GA Date: May 1972 A new concept in designing colour-and-co-we-nit effects is described and illustrated with samples. Read more
The bleaching of cotton with emulsions of hydrogen peroxide in perchlorethylene medium

Author: Van Rensburg, NJJ Date: Aug 1972 Cotton can be successfully bleached with emulsions of hydrogen peroxide in perchlorethylene by single step batch application. Read more
Properties of some fabrics from wool/nylon core spun yarns

Author: Shiloh, M ; Kruger, PJ ; Slinger, RI Date: Oct 1972 Mechanical properties of fabrics from wool and multi-filament nylon core yarns were measured and compared with other fabrics. Read more
A study of the forces involved in the withdrawal action during rectilinear

Author: Aldrich, V ; Kruger, PJ Date: Oct 1972 An 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
The cleanliness of rectilinear combed tops. Part 1: The influence of gauge setting and gill feed

Author: Aldrich, De V ; Kruger, PJ Date: Nov 1972 The influence of gauge setting and gill-feed on the efficiency with which the rectilinear comb removes impurities was investigated. Read more
The cleanliness of rectilinear combed tops. Part 2: The influence of the top comb and comb cylinder

Author: Aldrich, De V ; Kruger, PJ Date: Dec 1972 The influence of the gap between pins, percentage void, pin and pin thickness on the combing performance of comb was investigated. Read more
The cleanliness of rectilinear combed tops. Part III: The influence of a double top comb and a burr beater

Author: Aldrich, De V ; Kruger, PJ Date: Dec 1972 The combing performance of a double top comb was compared with that of a single top comb. Read more
Studies of some wool/polyester woven fabrics. Part 1: Blends of untreated wool and polyester fibres in plain weaves

Author: Shiloh, M ; Slinger, RI Date: Dec 1972 Plain weave, light weight sitting fabrics were constructed from blends of wool and three types of polyester fibres at various levels of composition. Read more
An analytical study of the point of rupture of two-fold wool worsted yarns

Author: Hunter, L Date: Feb 1973 The breaking strength and extension of a range of wool worsted hosiery and weaving yarns were related to the average linear density of the yarn segment and that of the yarn at the point of rupture. Read more
Studies of some wool/polyester woven fabrics. Part II: Shrinkproofed wool in wool/polyester blend fabrics

Author: Shiloh, M ; Slinger, RI Date: Mar 1973 Two 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
Scouring conditions. Part I: The effect of liquor pH during backwashing on the subsequent combing performance of neutral scoured wool

Author: Turpie, DWF Date: May 1973 The investigation described in this paper is the first of a series in which the objective is to find a set of scouring conditions, with particular emphasis on pH, which will give optimum results in subsequent mechanical processing. Read more
Some tensile properties of worsted yarns from wool blended with either polymide, polyester or acrylic fibres

Author: Aldrich, De V ; Grobler, A Date: May 1973 Some mechanical properties of wool, wool/polyester and wool/acrylic intimately blended yarns were investigated. Read more
