Abstract
Textiles are provided that include fibrous cellulosic materials having an α-cellulose content of less than about 93%, the fibrous materials being spun, woven, knitted, or entangled. The fibrous cellulosic materials can be irradiated with a dose of ionizing radiation that is sufficient to increase the molecular weight of the cellulosic materials without causing significant depolymerization of the cellulosic materials. Methods of treating textiles that include irradiating the textiles are also provided.
Claims14
A method of treating a textile, the method comprising:
- irradiating a textile comprising a fibrous cellulosic material;
- quenching the irradiated textile by applying pressure to the textile by mechanically compressing the textile in at least two dimensions at a pressure of at least 1000 psi, together with a sufficient quantity of beat to elevate the temperature of the textile to above a melting point or softening point of a component of the textile;
- and
- irradiating the quenched textile a second time with a second dose of ionizing radiation;
- wherein the fibrous cellulosic material has an alpha-cellulose content of less than about 80 percent, is selected from the group consisting of flax, hemp, jute, abaca, sisal, wheat straw, lignocellulose filler (LF), ramie, bamboo fibers, cuprammonium cellulose, regenerated wood cellulose, lyocell, cellulose acetate, and blends thereof, and is spun, woven, knitted or entangled.
