  • METHOD FOR PRODUCING REGENERATED CELLULOSE FIBERS FROM COTTON CONTAINING TEXTILE WASTE
    Publication number: 20190338466
    Abstract: The invention relates to a method for regenerating cellulose fibers from cotton-containing textile, wherein the degree of polymerization (DP) of cellulose in cotton is reduced by using a DP decreasing agent, which is an endo-cellulase of the type EC Number 3.2.1.4, together with mechanical energy. The DP of cellulose in cotton is reduced to under 1500, which makes it particularly suitable for the following steps, especially the spinning step. The cellulose is further dissolved using cellulose solvent comprising NMMO or an aqueous mixture of NMMO and the obtained cellulose-containing liquid is subjected to a spinning process to produce cellulose fibers.

  • Method for dyeing textile materials in a supercritical fluid
    Patent number: 6620211
    Abstract: In a method for dyeing textile material with one or more fiber-reactive disperse dyestuffs in a supercritical or almost critical fluid, such as CO2, which textile material is selected from the group consisting of silk, wool and cellulose, combinations thereof and combinations of one or more thereof with synthetic fibers, such as polyester and/or polyamide, the relative humidity of the fluid is in the range from 10-100% during dyeing. Textile materials which have been dyed with the aid of this method have properties which are at least equal to those of textile materials of the same type which have been dyed in the traditional manner using water-soluble dyestuffs. A device for carrying out the dyeing method is also disclosed.
