The characteristics of double pique wool fabrics knitted at different ratios of yarn intake. Part II Some additional physical properties

Author: Schulze, JE Date: Sep 1968 This paper which is a continuation of technical report no .95, reports on some additional physical properties of Swiss and French double pique fabrics knitted with the same yarn at three different ratios of yarn. Read more
Chemical modification and processing of phormium tenax fibres Part II: The influence of chemical and mechanical softening of fibre tenacity and yield

Author: Weideman, E ; Van der Walt, LT Date: Jan 1978 The relative importance of various parameters such as temperature, concentration and treatment time on the chemical softening and bleaching of phormium fibre, has been investigated on a pilot scale. Read more
Chemical modification and processing of phormium tenax fibres. Part 3: the effect of certain softening conditions on fibre, yarn and fabric properties

Author: Weidman, E ; Robinson, GA Date: Nov 1981 Phormium fibre was softened under different conditions and then spun with the aid of two different core yarns on the DREF system. Read more
Chemical modification and processing of phormium tenax fibres. Part I: A preliminary report

Author: Weidmann, E ; Grabherr, H Date: Aug 1977 Phormium tenax fibres have so far only used for the manufacturing of grain bags and affiliated products. Read more
Chrome dyes on wool: The influence of some shrink-resist treatments on residual chromium values

Author: Roberts, MB Date: Feb 1978 Residual chromium values were determined after dyeing untreated chlorinated and chlorine/ Hercosset treated wools with chrome dyes using various levels of dichromate. 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
Cockling in fully-fashioned knitwear Part II: An investigation into the effect of various fibre, yarn and fabric properties on cockling

Author: Robinson, GA ; Green, MV Date: Dec 1976 Cockling in fully fashioned knitwear has been investigated. Read more
Cockling in fully-fashioned knitwear. Part 1: A preliminary report

Author: Hunter, L ; Robinson, GA ; Green, MV Date: Jan 1976 Different forms of loop distortion including cockling are defined with the aid of photographs. Read more
Cockling in fully-fashioned knitwear. Part IV (4): The effect of fibre diameter, crimp and yarn linear density

Author: Robinson, GA ; Cawood, MP ; Dobson, DA Date: Aug 1978 An attempt was made to correlate certain fibre and yarn properties of some 21 lots of wool with the amount of cockling found in the resulting fully fashioned garments. Read more
The combing performance of different types of comb cylinders for rectilinear combs

Author: Aldrich, De V Date: Feb 1971 The combing performance of three types of comb cylinders were investigated, and compared on the basis of top cleanliness, mean fibre length of the top and fibre breakage. 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
The contamination of wool by high density polyethylene (HDPE) woolpack material

Author: Strydom, MA Date: Jun 1985 Pilot scale processing trials were carried out with wool which had been packed in a new low fibrillating, high density polyethylne. Read more
Continuous dyeing using radio frequency energy Part II: A preliminary study of the effects of disperse dye molecular structure of fixation

Author: Garner, E Date: Mar 1983 An attempt was made to gain an understanding of the mechanism of fixation of disperse dyes on polyester in a radiofrequency field. Read more
Continuous dyeing using radio frequency energy Part IV: The fixation of disperse dyes on pre-dried polyester

Author: Garner, E Date: Apr 1983 When polyester was padded with a number of disperse dyes, dried and then subjected to radio frequency energy, no dye fixation was obtained. Read more
Continuous dyeing using radio frequency energy Part V: Laboratory studies involving energy frequency and dye liquor conductivity

Author: Garner, E ; Barkenhuysen, FA Date: Apr 1986 The dyeing of cotton fabric with frequency (HF) energy was investigated and compared with conventional dyeing processes. Read more
