    摘要： This ultra-bulky fiber aggregate is obtained by blending (A) a polyester fiber and (B) a core-sheath type composite fiber wherein a low melting point component lower in melting point than the core is used for the sheath. The interlacing portions of three-dimensionally continuous fibers are fused by melting of the sheath portions of the core-sheath type composite fiber. The fiber aggregate has a thickness of at least 200 mm and a density of 0.02 to 0.1 g/cm.sup.3, and varies in density within .+-.5% in all of the longitudinal and transverse directions and the direction of height. The fiber aggregate can be used as a shoulder pad and a cushion material when it is cut. The production method of this fiber aggregate comprises blending (A) a polyester fiber and (B) a core-sheath type composite fiber using a low melting point component lower in melting point than the core for the sheath to obtain a card web, temporarily fusing card webs by far infrared rays or a hot air heater to laminate webs as required by a predetermined density and a predetermined thickness, and heat-treating the resulting laminate so as to mutually fuse the layers forming the laminate, wherein the heat-treatment is carried out by placing the laminate into a steam oven while it is compressed and clamped between two upper and lower plates and introducing the steam, the laminate being subjected to the heat-treatment while kept erect.

    摘要： A paper machine clothing, in particular a press felt, for a machine for producing or processing a fibrous material web, includes a base structure and at least one layer of nonwoven fibers disposed on the base structure. The layer of nonwoven fibers has bonding fibers and further fibers. The bonding fibers and the further fibers differ in at least one material property, and at least some of the bonding fibers are connected to one or more further fibers and/or elements of the base structure by an integral joining connection, in particular a weld connection. A method for producing the clothing is also provided.

    摘要： A method and apparatus are disclosed for binding a nonwoven material by means of a binding agent requiring heat for activation, particularly for binding cellulosic fibers with a thermoplastic material. The material is irradiated with an infrared radiation source, and surface burning of the irradiated material is prevented by passing a weak flow of air through the material. Inclined walls guide the air flow through the material in an inclined path directed from the edge of the infrared radiation source and towards the center thereof. Each infrared radiation source is surrounded by two side walls so that a space is formed between each side wall and the radiation source for the passage of the inlet air. The cross-sectional areas of these spaces are together approximately equal to the cross-sectional area of a suction channel positioned opposite the spaces. The air flow is controlled by means of two speed-regulated fans, one at the inlet and one at the outlet of the apparatus.
