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： 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.

摘要： A method for preparing a novel compound, i.e. a resinous material, characterized in that an epoxy compound is allowed to react with ammonium salt or a metal salt (for example, lithium salt, sodium salt, potassium salt, magnesium salt, etc.) of polyglutamic acid. The resulting reaction product is useful in a method for treating shaped materials especially polyester textiles. In this method the shaped materials are treated with the novel resinous material to improve the appearance and handling characteristics thereof. A process for providing a wooly finish on polyester textiles is characterized by treating textiles (including polyester knittings and mixed spun fabrics or knittings or mixed woven fabrics or knittings) in a bath of an emulsified mixed solution of an epoxy compound and a metal salt of polyglutamic acid containing a catalyst, and carrying out a heat-treatment of the resulted textiles after pre-drying.

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： The present invention provides a nonwoven fabric made of fine denier filaments of superior bulkiness, heat insulation property and tensile strength, and a production method thereof. This nonwoven fabric is made of fine denier filaments produced by first preparing. First a thermoplastic polymer component "A", then another thermoplastic polymer component "B" which is insoluble in the component "A" and of which the melting point is higher than that of the component "A" by 30.degree. to 180.degree. C. Adopting a bicomponent melt spinning method employing the component "A" and the component "B", the bicomponent conjugate filaments, on which surface at least component "A" is exposed, are obtained. By accumulating these bicomponent conjugate filaments, a web is formed. Then heat is applied to the predetermined areas on the web throughout its entire thickness, whereby only the component A is softened or molten, and the bicomponent conjugate filaments are heat bonded to one another, thus a fleece is obtained. The predetermined areas are shaped like dots or lattices and distributed with a certain space between them. After obtaining the fleece, a wrinkling action is applied to the fleece.
