TREATMENT OF FIBRES TO ENDURE PROCESSING |
摘要 |
The invention relates to a method of treating chemical pulp fibres by a polymerizing hydroxy acid, the fibres thus obtained and the products refined from them. In the method, the hydroxy acid reacts with the reactive groups of the fibres in the presence of a catalyst, forming ester bonds. The following units of the same hydroxy acid are oligomerized and/or polymerized to these grafted acid residues. The fibres thus treated and the products refined thereof endure better processing stages that include drawing and stretching than untreated fibres.
