Abstract

1373639 Producing bast fibres TEXTILIPARI KUTATO INTEZET 22 Nov 1971 [23 Nov 1970] 54078/71 Headings D1F and D2W Bast fibres for use in the textile industry and of substantially shive free fibres of retted or non-retted stalks in the form of loose, tangled, broken bundles of fibres, slivers, rovings or spun yarns are treated with hot water to wash the fibres, treated with an aqueous solution of a salt of an organic decarboxylic acid so as to remove pectin, treated with an aqueous solution of an oxidising agent so as to reduce the lignin content to less than 2% and treated with an alkaline solution. The removal of the pectin is carried out with an at the most 5% solution of said ammonium salt at a temperature of 80-100‹C for 20-60 minutes. The treatment to reduce the lignin content may be carried out with a 5-20 % solution of sodium chlorite at a temperature of 50- 100‹C for 20-90 minutes and with a subsequent treatment with a 2-10% alkaline solution at a temperature of 50-100‹C during 20-60 minutes. The fibres are subsequently bleached with a known oxidising agent, softened in known manner and dried.
