Abstract

Cotton fibres used for sanitary products have to meet both - the textile-technological and the pharmacological requirements. By hydrogen peroxide bleaching the fibres are purified from unwanted substances and become properly absorbable and white. Beside the bleaching, activating and stabilising agents, the wetting agents, which provide more efficient bleaching and shorter bleaching time, are added to the bleaching liquor. Since pharmaceutical regulations require complete removal of these agents from fibres, intense rinsing after bleaching is necessary and, consequently, large quantities of rinsing water are used. From ecological and economical reasons the bleaching processes, which would need smaller quantities of auxiliary agents or will use the agents that would be easily removed after bleaching, should be searched for. The quality of the processed fibres should not be affected, of course. Our intention is to monitor the amount of surfactants in rinsing water and the residue on fibres by using the methods prescribed for sanitary products by pharmacopoeia, and to test the suitability of the method for determination of total organic carbon (TOC) in such solutions. We also intend to perform bleaching with peroxiacetic acid which is ecologically adequate bleaching agent. The whiteness of the processed material would be determined colorimetrically on a remission photometer and typical mechanical and physical properties of the material prior and after processing would be identified. A part of researches would be dedicated to polypropylene nonwovens designet for sanitary products and agrotextiles. The possibilities of improving mechanical and permeability properties of fibres as well as the possibilities of streamlining their products would be investigated. We intend to manufacture the nonwovens from the blends of fibres of different manufacturers which would provide more cost-effective production. As to the agrotextiles our intention is to determine their UV permeability.
