Abstract: Described is a method for decoloring of a textile material, the method includes the steps of: providing a textile material; providing an alkaline solution containing one or more anionic polyelectrolytes; treating the textile material in the alkaline solution during a treatment period; and recovering at least some of the textile material from the alkaline solution.

Abstract: A process for separation of the cellulosic part from a raw material composition comprising polyester and cellulose is provided. A blend is prepared comprising a raw material composition comprising polyester and cellulose and a hydrolyzing liquor wherein the hydrolyzing liquor comprises a first mixture comprising an alkaline solution containing hydroxide ions. The hydrolyzing liquor is added to give the blend an effective alkali concentration in a range from 5 g/l to 150 g/l, wherein the effective alkali concentration is calculated as NaOH, and the hydrolyzing liquor:raw material composition ratio is from 1.5:1 up to 25:1 and keeping the blend at a temperature of 100° C. or above.

Abstract: The present invention relates to a method for producing powdered cellulose. The method comprises the steps of providing dry pulp starting material, heat treating the dry pulp starting material to a temperature of 100-200° C., for less than 1 hour, and refining the heat-treated dry pulp starting material to particles having d97<500 ?m.

Abstract: A circular saw mounting device which rotatably supports a saw blade in a grinding machine is disclosed. The mounting device comprises a base plate adapted for mounting in a grinding machine; a centering element comprising at least two engagement elements configured to be operated in a radial direction between a mounting position and a locking position. According to the invention the mounting device further comprises an actuator comprising a pin being configured to be operated in an axial direction and arranged to engage with pivot articulated couplings to each of the engagement elements to thereby transfer a radial displacement to the at least two engagement elements and to thereby operate the at least two engagement elements between the mounting position and the locking position.

Abstract: A circular saw mounting device which rotatably supports a saw blade in a grinding machine is disclosed. The mounting device comprises a base plate adapted for mounting in a grinding machine; a centering element comprising at least two engagement elements configured to be operated in a radial direction between a mounting position (M) and a locking position (L). According to the invention the mounting device further comprises an actuator comprising a pin being configured to be operated in an axial direction (A) and arranged to engage with pivot articulated couplings to each of the engagement elements to thereby transfer a radial displacement to the at least two engagement elements and to thereby operate the at least two engagement elements between the mounting position (M) and the locking position (L).

Abstract: The present invention relates to a process for manufacturing a composite article comprising cellulose pulp fibers and a thermoplastic matrix, wherein said process comprises the steps of: a) mixing a refined aqueous pulp suspension with a water suspension of thermoplastic fibers into a composition, b) forming the composition into a fiber web, c) dewatering the fiber web, d) drying the fiber web, and e) heating and pressing the dried fiber web from step d) to melt said thermoplastic fibers into a thermoplastic matrix and form a composite article.

Abstract: The present invention relates to a process for producing an oxidised cellulose pulp fibrillar network and a composite with lignocellulosic fibres comprising the following steps: (a) oxidising a cellulose pulp to obtain about 0.3 to 2.5 mmol carboxylic groups per gram cellulose pulp; and about 0.1 to 5.0 mmol aldehyde groups per gram cellulose pulp; (b) homogenisation of the cellulose pulp of step (a) wherein the cellulose fibres are refined to provide a cellulose pulp comprising 0-50% of fibres having an average length 0.7 mm-2.1 mm; and 50-100% of fibres having a particle size of 0.05-500 micrometer (?m); and optionally (c) combining with lignocellulosic fibre. Also step (d) drying of the cellulose pulp obtained by step (b) or step (c) may be included in the process.
