Abstract:
A method for manufacturing semifinished products with felt effect for hats, starting from a woven or non-woven textile material comprising felting fibres and heat- shrinkable fibres, said material being felted by needle- punching, surface treated, and subjected to partial thermoforming.
Abstract:
A planar substrate has a moisture activated shrinking filament applied thereon. When wetted, the shrinking filament shrinks and causes the planar substrate to gather and pucker. The planar substrate with the filament thereon may be compressed into a compact shape when in a dry state.
Abstract:
A repair fabric for pipe repair in which a curable resin is impregnated in order to rigidise such fabric in use. The fabric being formed from a non-woven fabric which is heat shrunk to reduce fibre interstice spacing and increase capillary penetration of such fabric by the curable resin. The fabric being heat shrunk by up to 25 % in terms of the fabric density increase and typically at a temperature of 145-160 DEG C.
Abstract:
New filtering material comprised by a needled felt of synthetic curled macro fibrilae, obtained by fibrilation of a laminated film with two olefine components of different natures, and subjected to a thermal treatment; said fibrilae having a rectangular cross section area and a titre comprised between 8 and 20dtex. Respiratory mask comprised of three shells (CI.MF.CE) of different shapes, the intermediate shell (MF) being made with the present new material and enclosed between the two outer shells welded thereon (SUS) at the periphery thereof, the marginal portion (A) of the intermediate shell (MF) filling a groove of the inner shell (CI) to form a bead (BR).
Abstract:
The present invention relates to an arrangement for manufacturing spunlace material, comprising a forming station (1) and an entangling station (2), wherein the forming station includes a first fibre former (6) for air-laying staple fibres, and a second fibre former (7) for air-laying short fibres on an underlying forming wire (8), on which the air-laid fibres are retained with the aid of a subpressure created in a suction box (15) positioned beneath the forming wire and with the aid of which the formed mat of fibres is transported to the entangling station (2). According to the invention, at least one screening element (16) is arranged beneath the fibre former (7) for short fibres such as to screen-off the subpressure and therewith create one or more regions on the forming wire on which no short fibres will be laid when the forming wire passes the fibre former (7) for short fibres. The invention also relates to a method for manufacturing spunlace material and to an absorbent, disposable article which includes such spunlace material.
