Described is a module for the treatment of fibres for obtaining a non-woven fabric. The module comprises a fan unit configured for generating a flow of air through a closed path and a chamber for the treatment of the fibres positioned in fluid communication with the closed path, delimited on opposite sides by respective side panels. Each side panel comprises a first gap defining a blowing portion of the closed path and a second gap defining a suction portion of the closed path. Each side panel defines a branch of the closed path which extends between the fan unit and the treatment chamber. The module also comprises a first platform and a second platform comprising respective first and second channels placed in fluid communication with the first gap and second gap of each side panel and with the treatment chamber to define connecting portions of the closed path. The fan unit is positioned equidistant relative to the treatment chamber in such a way that the flow of air is divided symmetrically between the branches of the closed path.

The invention relates to polyurethane and/or polyorganosiloxane copolymer compounds and salts thereof that contain carbodiimide moieties of formula [I]. Further, the invention relates to a process for the preparation thereof, to precursors for the preparation thereof, and to reactive compositions which contain such precursors and to their use for treating or finishing fibers, including hair and wool, and for permanently finishing, treating, impregnating textiles and leather or synthetic leather and other fibrous materials, and sheet materials and paper.

Provided herein is a method for decolorizing textile materials under hydrothermal conditions using dye adsorbent materials. The process is non-toxic and environmentally friendly, and the adsorbent materials can be repeatedly used. The textile materials are textile materials dyeable with disperse dyes. Further provided is a system for decolorizing textile materials. The decolorization system is designed to allow the adsorbent materials to react with the textile materials in a contact manner and a non-contact manner.

The present invention relates to a sizing composition for mineral fibers, especially glass fibers or rock fibers, containing a liquid phenolic resin having a free formaldehyde content, expressed with respect to the total weight of liquid, of 0.1% or less and an extender. Preferably, the liquid phenolic resin is mainly composed of phenol-formaldehyde and phenol-formaldehyde-amine condensates and has a water dilutability, at 20 C., at least equal to 1000%. Another subject of the present invention is the insulating products based on mineral fibers treated by said sizing composition.

A method of digital printing and finishing for fabrics is provided. The method includes a step of unwinding a fabric from a first reel. A step of compensating the speeds and of spreading the fabric for its positioning on a conveyor belt provided with supporting elements on which a digital printing step occurs is provided. A step of drying the fabric is provided. A step of winding the fabric onto a second reel is provided. These steps are being executed at corresponding stations arranged in sequence with respect to each other and the fabric passing through them continuously, transversely to the conveyor belt, there being a plurality of bars provided with printing heads which are controlled electronically and synchronized with the movement of the conveyor belt.
