Abstract: This invention relates to a producing procedure of an anti-“Methicillin-Resistant Staphylococcus Aureus (MRSA)” chitosan containing antibacterial High Wet Modulus (HWM) rayon fibre textile for medical usage. The steps are as following: chitin flakes made from natural shrimp or crab shells are deacetylated to generate chitosan with a high deacetylation degree of 90% or more. Next chitosan is dissolved in acetic acid and regenerated by caustic soda to form a chitosan antibacterial nanoparticles slurry, then added to HWM viscose rayon process, and spinning to produce a chitosan containing antibacterial HWM rayon fibre. The antibacterial amino groups of chitosan and the hydroxyl groups of rayon cellulose combine together via hydrogen bonding. Therefore, the fiber becomes the anti-MRSA antibacterial HWM rayon fibre containing amino groups (—NH3+). Finally the resulting HWM rayon fibre is conducted via a yarn spinning or/and weaving process to procure a medical textile with chitosan content.

Abstract: A composite polyester and cotton yarn is formed by blending polyester fibers with cotton fibers which have been regenerated from waste cotton material such as trimmings and cuttings from the apparel manufacturing industry. The fibers are cleaned and blended, then carded to align the fibers into strands. Depending on the size and texture of the desired yarn, the fibers are stretched and drawn into slivers prior to spinning to join the fibers together.

The resultant yarn is stronger and more absorbent than yarns made solely out of regenerated cotton fibers. The yarn is suitable for producing woven or knit fabric for the production of colorful and functional clothing and home textiles without the need for further bleaching or dyeing.

Abstract: A method of and an apparatus for producing a blended yarn from cotton fibers and man-made or synthetic fibers. According to conventional methods the blending of cotton fibers and man-made fibers has been hitherto effected subsequent to a cotton combing process. In order to obtain an appropriate yarn quality, it is necessary to comb out the cotton and thereby separate the short fibers thereof. With the prior art method of bringing together or combining the blend constituents subsequent to the cotton combing process, there have been problems with regard to a homogeneous blending of cotton and man-made fibers. A great number of machines is thereby required and the corresponding constructional expenditure is high. Therefore, a method and an apparatus are suggested and according to which the two blend constituents, namely cotton fibers and man-made fibers, are already brought together or combined prior to the combing process.

Abstract: A novel synthetic yarn is disclosed which comprises fibers of different lengths (as specified). At least three groups of synthetic fibers are present in the yarn, with the synthetic fibers within each group being substantially uniform in length. The substantially uniform length of each group of synthetic fibers present in the yarn differs from the substantially uniform length of the synthetic fibers in the other groups.
