    摘要: An insulating element for buildings and more particularly, for walls, ceilings and roofs, consists of a sheepswool fleece which is sandwiched between two layers of needled non-woven material consisting of sheepswool. The fleece and the needled non-woven material are connected together by fibers thereof to constitute a unit able to be handled as such.

    摘要: A fibrous, porous web material of the heat seal type having improved particulate retention properties for use in the manufacture of beverage infusion bags. The material comprises juxtaposed, successively wet laid first (1), second (5) and third (7) fibrous layers, at least one of said layers incorporating heat sealable fibres. The fibres in the first layer are of greater aspect ratio than those in the second layer which are of higher aspect ratio than those in the third layer.

    摘要: Nonwoven fabrics and fabric laminates are formed from continuous filaments or staple fibers of a select blend of specific grades of polyethylene and polypropylene which give improved fabric performance not heretofore recognized or described, such as high abrasion resistance, good tensile properties, excellent softness and the like. Furthermore, these blends have excellent melt spinning and processing properties which permit efficiently producing nonwoven fabrics at high productivity levels. The polymers are present as a lower-melting dominant continuous phase and at least one higher-melting noncontinuous phase dispersed therein. The lower-melting continuous phase forms at least 70 percent by weight of the fiber and comprises a linear low density polyethylene polymer of a melt index of greater than 10 and a density of less than 0.945 g/cc. At least one higher-melting noncontinuous phase comprises a polypropylene polymer with melt flow rate of greater than 20 g/10 min.
