Passive and active protection of cotton textiles
article
In rotproofing of cotton a distinction is made between passive and active protection. In passive protection, the structure of the cotton fibre is modified in such a way that the fibre can longer be attacked. This modification of structure can be effected on different levels: microscopical, submicroscopical and molecular. In active protection, the fabric is impregnated with compounds that are more or less toxic to the invading micro-organisms. A number of methods are discussed, including some methods developed by the Central Laboratory TNO.
The difference betwee n active and passive protection is illustrated through a laboratory experiment, using cellulase extracts, and with the results of a large outdoor exposure of treated fabrics. The merits of rotproofing in general are discussed, especially in connection with the Dutch textile production.
