CotonLe coton est une fibre végétale qui entoure les graines des cotonniers "véritables"(Gossypium sp.), un arbuste de la famille des Malvacées. Cette fibre est généralement transformée en fil qui est tissé pour fabriquer des tissus. Le coton est la plus importante des fibres naturelles produites dans le monde. Depuis le XIXe siècle, il constitue, grâce aux progrès de l'industrialisation et de l'agronomie, la première fibre textile du monde (près de la moitié de la consommation mondiale de fibres textiles).

| Résumé : |
Attempts were made to manufacture leatherboard from the short fibers of chrome collagen recovered by disintegration of the flesh split from chrome leather, for which there is no other use. Basic conditions of leatherboard manufacture were investigated. Materials used for the leatherboard were chrome collagen fiber, cotton, kraft pulp, and chrome shavings. The results of the experiment were as follows: 1) The time required for beater treatment was two hours for a mixture of one part chrome collagen fiber and one part cotton (Material A), four hours for a mixture of one part chrome collagen aber and one part kraft pulp (Material B), and eight hours for a mixture of three parts chrome collagen fiber, three parts shavings, and four parts kraft pulp (Material C). 2) The optimum fiber length of chrome collagen fiber was 0.5 cm. for Material A, but the fiber length of chrome collagen fiber had little effect in the cases of Materials B and C. 3) With regard to the ratio of materials, a ratio of at least over 40 percent cotton or kraft pulp is desirable. When shavings are used, the ratio should be not more than 20 percent. 4) With regard to the binder for the leatherboard components, there is no difference between ethyl acrylate and butadiene-acrylonitrile, and a satisfactory effect can be obtained with either of them with an impregnated quantity of 10 to 20 percent. |
