A laboratory investigation of the shrinkresist treatment of wool with polymide epichlorohydrin-polyacrylate polymer dispersions

Author: Van Rensburg, NJJ Date: Jun 1975 Some factors affecting the shrinkresist treatment of wool by chlorination followed by a treatment with a polyamide epichlorohydrin (PAE)-polyacrylate dispersion were studied. Read more
A laboratory study of the interrelationship between wool scouring efficiency and the partition of detergent during subsequent centrifuging

Author: Mozes, TE ; Van Rensburg, NJJ ; Turpie, DWF Date: Dec 1981 A laboratory study of the use of twenty nonionic detergents for scouring of raw wool showed that scouring efficiency decreased with an increase in the detergent partition coefficient obtained by centrifuging of artificial creams prepared with ...

Observations on some flame-retardant treatments of cotton/polyester blended fabrics

Author: Van Rensburg, NJJ Date: Jun 1974 All cotton, polyester and cotton/polyester blended fabrics containing 80, 60 and 40 percent cotton were treated with trisphosphate or titanium tetrachloride/antimony oxide. Read more
Resin treatment of cotton fabrics in the slack state in liquid ammonia

Author: Barkenhuysen, FA ; Van Rensburg, NJJ Date: May 1980 Lightweight and heavyweight cotton fabrics were treated in the slack state with a solution of DMHEU resin and NH4NO3 catalyst in liquid ammonia. Read more
A review of fire accidents, flammability and toxicity of burning textiles

Author: Van Rensburg, NJJ Date: Sep 1982 The effect of fire and its products (heat, smoke and irritant or toxic gases) on the human being, as well as the response of people in a fire situation, are reviewed. Some data on the causes of fire injuries are given and the factors causing ... Read more
A review of low add-on and foam application techniques

Author: Van der Walt, GHJ ; Van Rensburg, NJJ Date: Feb 1984 The wet processing of textiles is an energy-intensive operation and can consume as much as 80% of the total amount of energy required to produce a textile product from fibre. One factor that will become increasingly dominant in future planning ... Read more
SAWTRI Special publication: A review of fire accidents, flammability and the toxicity of burning textiles

Author: Van Rensburg, NJJ Date: Sep 1982 The products formed by the combustion of textile fibres and the relative toxicity ratings of a number of textiles are discussed in this paper. Read more
Some chemical properties and the response to liquid ammonia and sodium hydroxide of various South African cotton cultivars

Author: Barkenhuysen, FA ; Van Rensburg, NJJ Date: Oct 1982 Some chemical properties of various South African cotton cultivars, and their response to mercerising treatments were determined. Read more
Some sorption and X-ray characteristics of cotton fibres treated in yarn form with anhydrous and aqueous liquid ammonia

Author: Barkenhuysen, FA ; Van Rensburg, NJJ Date: Jul 1984 The modification of the structure of bleached cotton treated in yarn from with anhydrous liquid ammonia and liquid ammonia containing as much as 15% water was determined with the aid of iodine and moisture absorption tests, X-ray diffraction ... Read more
Sorption and X-ray diffraction studies on cotton fabrics treated in anhydrous and aqueous liquid ammonia

Author: Barkenhuysen, FA ; Van Rensburg, NJJ Date: Aug 1981 The effect of anhydrous and aqueous liquid as well as sodium hydroxide on the sorption of moisture, iodine and barium hydroxide by cotton was investigated. Read more
Studies on the surface chemistry of wool. Part II - The critical surface tension of wool and polymers - some results and a reinterpretation of the theory on surface interactions

Author: Weideman, E ; Van Rensburg, NJJ Date: Nov 1976 A 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
A study of the limiting oxygen index of cotton samples treated with titanium tetrachloride and antimony oxide

Author: Robertson, AD ; Van Rensburg, NJJ Date: Oct 1973 The limiting oxygen index values of cotton fabrics which had been treated with various reagents were determined. Read more
A study of the limiting oxygen index of cotton samples treated with titanium tetrachloride and antimony oxide

Author: Robertson, AD ; Van Rensburg, NJJ Date: Oct 1973 The limiting oxygen index values of cotton fabrics which had been treated with various reagents were determined. Read more
A study of the surface and total cyclic trimer content of polyester filament yarns and staple fibres available in South Africa

Author: McCormick, SG ; Van Rensburg, NJJ Date: Mar 1977 The 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
