摘要:
The present invention is generally directed to a process for making fabrics containing cotton fibers more aesthetically pleasing and resistant to staining by anionic dyes by derivatising the cotton so that it exhibits a permanent anionic charge. By increasing the anionic charge of the fibers, the fibers become resistant to anionic coloring agent which may undesirably come into contact with the fibers and the fibers can absorb greater amounts of cationic softeners and biocides. Furthermore, the negative charges repel each other resulting in a fabric with greater loft and hydrophilicity. This results in greater smoothness, better hand, and more comfort. Besides being used to prevent the cross-staining of fabrics, the present invention can also be used to make carpet materials resistant to anionic staining agents.

A method to treat fibrous materials for use in the formation of a biocomposite material that significantly reduces or eliminates the odors emitted from the fibrous materials is provided. In the method, the fibers or fibrous materials are initially treated to extract the raw fiber from the source plant material and the remove unwanted fractions of the fiber, such as the hemicellulose, lignin, and pectin, among others, leaving only the intact cellulose fibers. These cellulose fibers are then further processed in a second step to remove the odor from the cellulose fibers. The second step includes a combination of a second chemical treatment, dehumidification, and/or a cold plasma modification to render the cellulosic fibers odorless.
摘要:
The present invention relates to materials having antimicrobial properties, said materials comprising a polymer having incorporated therein a synergistic combination of at least two metal oxide powders, comprising a mixed oxidation state oxide of a first metal and a single oxidation state oxide of a second metal, the powders being incorporated substantially uniformly within said polymer, wherein the powders have substantially different specific gravities and substantially similar bulk densities and wherein the ions of the metal powders are in ionic contact upon exposure of said material to moisture. There are further provided methods for the preparation of said materials and uses thereof, including in combating or inhibiting the activity of microbes or microorganisms.

The invention discloses a composition of oil for the jute industry, particularly for jute batching application. The composition is free from PAH compounds, hence is non-carcinogenic. It is made from highly refined premium quality mineral base oil, mixed with carefully selected additives as emulsifiers. These are mixed to yield a readily emulsifiable product. It is further mixed with water for instantaneously preparing an oil-in-water emulsion which is sprayed on raw jute. The composition is bio-degradable, hence eco-friendly, non-toxic and results in lower consumption (>20%) as compared to existing products. It has non-ionic emulsifiers, it is colourless and odourless and is suitable for producing jute products meeting as per international requirements.

摘要:
For improving the chemical and/or physical properties of hollow-structure natural fibers, such as kapok fibers, said fibers are subjected to a process, which determines the internal coating and/or filling thereof, at least partly, with a substance capable of improving the chemical and/or physical properties of the fibers.
