A heat-insulating protective member for skid posts contains a needled blanket of inorganic fibers. At least some of the needled blanket has, disposed therein, an impregnation part where an oxide-precursor-containing liquid is adherent in an undried state. The impregnation part has a water content of 50-400 parts by mass per 100 parts by mass of the inorganic fibers of the impregnation part. The water content of the heat-insulating protective member is 50-400 parts by mass per 100 parts by mass of the inorganic fibers of the heat-insulating protective member. The oxide-precursor-containing liquid contains ingredients that, upon burning, yield a composition containing Al.sub.2O.sub.3 and CaO. The oxide-precursor-containing liquid is adherent in an amount of 2-50 parts by mass in terms of oxide amount per 100 parts by mass of the inorganic fibers of the impregnation part. A molar ratio of Al/Ca, in the whole impregnation part is 10-330.

A non-woven insulation material, suitable for use in the manufacture of clothing, furnishing or the like, said material comprises a layer of fibres comprising a plurality of discrete apertures extending at least partially through the material.

Disclosed is a napped artificial leather including: an artificial leather base material that includes a non-woven fabric of polyester fibers having a Young's modulus of 1 to 6 GPa, an average fiber-toughness of 8 to 40 cN.Math.%, and a crystallinity of 35% or less, and an elastic polymer, the artificial leather base material having, on at least one surface thereof, a napped surface on which the polyester fibers are napped. Also disclosed are polyester fibers having a Young's modulus of 1 to 6 GPa, an average fiber-toughness of 8 to 40 cN.Math.%, and a crystallinity of 35% or less, and a non-woven fabric including the polyester fibers.

Process for transforming synthetic and vegetable fibres into a non-woven fabric of the type which provides the following sequence of processing steps: flock opening step, during which fibrous materials of different shapes and sizes are transformed into fibre flocks of different lengths; drawing and treatment step of the material selected in the previous step; cutting and trimming step: once the drawing and treatment step of the material has been completed, the non-woven fabric is subject to longitudinal cutting and trimming, to make a series of rolls, usually two or three, for final use, characterised in that, after the opening step, the flocks are transferred to a condenser, where the long-fibre flocks are separated from the short-fibre flocks, by means of a perforated mesh screen.

A CIPP liner for repairing a sewer pipe comprises a cover fabric (1) and a base fabric (2) to be attached to each other using needle punch technology, as well as a stretchable plastic membrane (4) attached to the base fabric (2) with a flexible glue (3), into which flexible glue (3) also the with each other mixed fibres (5) of the cover fabric (1) and the base fabric (2) are glued. From this material, a CIPP liner corresponding to the dimensions of the sewer pipe is cut and sewn, the sewing seam of which is further taped.

Fibrous material webs and methods of making the fibrous material webs. Binderless webs can be formed in a continuous process where fiber material, such as glass is melted and formed into fibers. The fibers are formed into a web of binderless glass fibers or a web with a dry binder. The binderless web or the web with dry binder can be layered and/or the fibers that make up the web can be mechanically entangled, for example, by needling.
