A sizing composition for fibers and yarns and/or fabrics made from such fibers, comprises chitosan having a molecular weight Mvof 150.000 Da, with a degree of deacetylation of 75-85% and an ambient temperature viscosity of 20-200 cps, said chitosan being dissolved in a 3% to 9% w/v acetic acid or citric acid solution, 3-9% v/v.
A process for improving the chemical and/or physical properties of a yarn comprises a step of applying a chitosan-based reinforcement product, a later step of crosslinking the chitosan and a partial and calibrated desizing step for removing the crosslinked chitosan, said desizing step being carried out by mechanical means.

PROCESS FOR IMPROVING THE CHEMICAL AND/OR PHYSICAL PROPERTIES OF HOLLOW-STRUCTURE NATURAL FIBERS
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.

A PROCESS OF MAKING A YARN HAVING WEAVABILITY FEATURES AND A PROCESS OF WEAVING SUCH YARN
A process of making a yarn having weavibility features, comprising the steps of providing a fine yarn which comprises an intimate blend of first fibers and polyvinyl alcohol fibers. Advantageously, before spinning, said fine fiber yarn undergoes a sizing step, to obtain a sized fine yarn having an increased tensile strength as compared with the tensile strength of the original fine yarn. The first fibres are selected from natural animal fibers, vegetable fibers, non-water- soluble synthetic polymer fibers, man-made natural polymer fibers, continuous filaments of animal origin and/or discontinuous filaments of animal origin.
