EXTRACTING FIBRES FROM FIBRE FEEDSTOCK
A method of extracting natural fibres from a fibre feedstock, the fibre feedstock comprising gum between the natural fibres. Fibre feedstock is introduced into water with a first oxidizing agent. The first oxidizing agent partially reacts with the gum. The oxidizing agent is modified, such as by introducing a second oxidizing agent or reducing the concentration of the first oxidizing agent, and reacts with the partially reacted gum. The released fibres are then removed from the water.

WATER-SOLUBLE REGENERATED FIBER PRODUCTION FROM CALLUNA VULGARIS PLANT SPECIES
The method disclosed relates to production of regenerated fiber from cellulose-containing plant species, in the textile sector. In particular, the method relates to obtaining water-soluble regenerated cellulose fiber using high or low purity cellulose raw material isolated from the wild plant species of Calluna Vulgaris.
METHOD FOR MANUFACTURING FISHING NET
Provided is a method for manufacturing a fishing net formed from a plastic net that can be handled by winding or folding although the net has plastic rigidity. The fishing net is manufactured by (1) a step of preparing a multifilament yarn formed by bundling a plurality of core-sheath type composite filaments, in each of which a core component is made of polyethylene terephthalate and a sheath component is made of polyolefin, (2) a step of preparing a yarn thread obtained by paralleling a plurality of the multifilament yarns, (3) a step of twisting or braiding four yarn threads 11, 12, 13, 14 to obtain a net constructed with strands 1 and intersections 2, (4) a step of heat-treating the net under without pressure to melt the sheath component of the yarn threads 11, 12, 13, 14 constituting the strands 1 and the intersections 2, followed by solidifying, thus obtaining a plastic net, and (5) a step of forming the fishing net using the plastic net.
PRODUCTION OF PAPER YARN FROM CELLULOSE-CONTAINING PLANT SPECIES
The method disclosed relates to the production of paper yarn from cellulose-containing plant species, in the textile sector, and particularly relates to obtaining a paper yarn by a wet spinning method using high or low purity cellulose raw material isolated from the wild plant species of Calluna Vulgaris.

Structural and Decorative Composite Material, Preparation Method Therefor, And Article Containing Same
Provided are a composite material and a preparation method therefor. The composite material comprises: a base layer; a first plant fibre fabric located on the upper surface of the base layer; optionally, a second plant fibre fabric located on the lower surface of the base layer; and resins present in each layer. The composite material has a decorative performance and an improved mechanical performance.
Comprehensive process for selectively separating lignocellulosic biomass into purified components with high yield
A comprehensive process for treating lignocellulosic biomass in order to separate the biomass into its component parts, the process comprising: a) contacting the lignocellulosic biomass with a first solvent for a period of time and at a first temperature at a severity in the range of about 2 to about 4 to remove extractive components and a portion of ash from the biomass; b) contacting the biomass from step (a) with a second solvent, and optional catalyst, at a second temperature at a severity in the range of about 1 to 5 to remove hemicelluloses and additional ash from the biomass; and c) separating the biomass from step (b) into a lignin product and a cellulose product by contacting the biomass from step (b) with a third solvent at a severity in the range of about 1.5 to 5 to provide a spent liquor product and a solid fraction containing cellulose.
