摘要： This invention is concerned with the tack spinning of materials and has particular reference to the formation of tack spun materials by applying a thermoplastic polymer to a backing or carrier sheet to form a pattern or layer thereon and then heating the layer and contacting the layer with a second surface whereby separation of the carrier from the second surface results in separation of the thermoplastic polymer within its plane to draw fibres therefrom on progressive separation. The preferred embodiment of the invention involves two backing sheets prepared between a pair of nip rollers to form a sandwich structure with a layer of thermoplastic tack spinnable material and separating the same on the downstream side of the nip to provide the fibres disposed substantially transverse to the plane of the carrier sheet. The invention also describes novel apparatus for performing this operation.

摘要： This invention relates to a heat activatable adhesive formed from at least two components each in the form of discrete, flowable particles which are capable of adhering in abutment of one particle with another to provide an open structured, porous matrix. The adhesive may be in the form of a sheet formed by blending the particles of each component, applying the mechanical mixture to a supporting sheet, heating the mixture and supporting sheet to the temperature at which the material with the lowest tackifying temperature becomes tacky, applying pressure sufficient to partially flatten the largest particles to a degree such that their minimum dimension is substantially equivalent to the thickness of the layer formed on said support sheet and during or after said pressure application.

摘要： Filaments having a substantially increased inner surface, in particular porous filaments of filaments having a cracked, notched or nicked surface of thermoplsatic material are produced by subjecting filaments of thermoplastic material, preferably containing a pore-forming agent, to a heating medium at a temperature at least 100.degree., preferably 150.degree.C. above the glass transition temperature of the thermoplastic material, preferably near or above its softening point, the temperature of the heating medium and the time of exposure of the filaments thereto being such that the peripheral portions of the filaments are affected by the heat treatment to a substantially larger degree than the core portions creating within the filaments temporarily a temperature gradient between the core and periphery of the filaments, the temperature at the periphery being sufficient to reduce the intermolecular cohesion of the thermoplastic material at the periphery, and the action of heat at the core being substantially lower than at the periphery.

摘要： A method for the incorporation of an active agent into a porous structural substrate which comprises forming a pseudoplastic gel comprising:an active agentat least one solvent thereforand at least one gel forming agent and thereafter applying the gel to the structure to be treated. The penetration of the gel into the porous structure may be regulated by decreasing the viscosity of the gel by increasing the shear on the gel during its application to the porous structure. A predetermined gel penetration of the structure is achieved before 75% of the solvent has evaporated.
