摘要： A nonwoven fabric of superior uniaxial elasticity is provided. The nonwoven fabric comprises of conjugate filaments each of which is about concentric sheath-core type. Core component is composed of polyester and sheath component is composed of polyolefine. In the nonwoven fabric, heat bonded areas are interspersed by heat bonding the conjugate filaments one another by softening or melting the sheath component. The nonwoven fabric satisfies following four properties concurrently: (i) breaking elongation in cross direction is 150% or more, (ii) ratio of breaking elongation in cross direction to breaking elongation in machine direction is 5 or more, (iii) percentage of elastic recovery at the time of extending the nonwoven fabric by 50% in cross direction is 60% or more, and (iv) percentage of elastic recovery at the time of extending the nonwoven fabric by 100% in cross direction is 50% or more. A heat is partially applied to a filamentous web, thereby obtaining a filamentous fleece. The filamentous fleece is extended in cross direction and a heat drawing is applied to the filamentous fleece at a drawing ratio of 10 to 80% in machine direction, and a heat setting is applied to the filamentous fleece, thereby an elastic nonwoven fabric is obtained.

摘要： The present invention relates to a nonwoven fabric including a fine denier filament having a plexifilamentary structure in which the disadvantages of polyolefins and of polyesters are offset each other while advantages of them are well utilized with a fine fibrillated structure comprising said filament. The filament comprises a mixture which is at least composed of polyolefin and polyester which are immiscible with each other and has a plexifilamentary structure. The filament is so highly fibrillated that the fibril has not been available yet and, in addition, the filament is with high strength and modulus and exhibits a good dyeing ability. The above-mentioned nonwoven fabric contains the filaments having a plexifilamentary structure in which a mixture of polyolefin and polyester which are immiscible with each other in a mixing ratio within a range of from 5/95 to 95/5 by weight and said filaments are entirely or partially bonded. Said nonwoven fabric is with excellent strength, moisture permeability and waterproof pressure and exhibits a dyeing ability.

摘要： A formable biodegradable filament nonwoven fabric and a production method therefor are provided. A biodegradable polymer comprising a thermoplastic aliphatic polyester as its principal component is melted and extruded through a spinneret into filaments. While being quenched with quench air blow, the extruded filaments are drafted at a drafting speed of 1,000 to 2,500 m/min by means of a suction device disposed below the spinneret. The drafted filaments are spread and accumulated on a movable collector surface thereby to be formed into a web, which is then treated for formation of a nonwoven fabric. The constituent filaments of the nonwoven fabric has a polymer supercool index of 0.3 to 0.6.
