    Abstract: The present invention relates to a polyester product excellent in resilient elasticity, shape retainability and shape stability, and a process for producing the same. The invention provides a polyester product with high resilient elasticity, shape retainability, and shape stability, which is produced by heat-treating a product comprising polyester fibers or a film prepared by taking up a molten polyester at a take-up speed of 2000 m/min to 4000 m/min, in wet heat and/or dry heat at not lower than 120 DEG C with the product maintained in a loose or constrained condition without being drawn. The product is very suitable, for example, as a collar interlining cloth of a shirt, a base fabric of a shirt, or a fabric of a lady's dress, etc.

    Abstract: The present invention relates to a method and apparatus for producing nonwoven fabrics. It has been impossible to obtain broad uniform nonwoven fabrics, unless a large number of spindles ejecting fibers are installed in the widthwise direction of the fabric. In view of this, the present invention relates to a novel method and apparatus for producing nonwoven fabrics capable of increasing the width of the fabric even when a small number of spindles are employed. The method of producing nonwoven fabrics according to the present invention comprises the steps of ejecting a group of fibers entrained with a high-speed fluid through a nozzle rotating around the axis of a substantially stationary cylindrical support, laminating the ejected fibers in the form of a web on the inner peripheral surface of the cylindrical support, resiliently compressing the heated web via a roller revolving on the inner peripheral surface of the cylindrical support around the axis of revolution corresponding to that of rotation of the nozzle, and then taking back the web from the cylindrical support while letting the web slip thereon. The apparatus according to the present invention is used to embody the above-described method.

    Abstract: Process for mfg. nonwoven cloth in which fibres transported by a high-speed fluid are gathered as a web and then let to a cloth wrapper to be made an overlapping web. Pref., the web has a cross sectional distribution such that its weight per unit area gradually decreases going towards the edges of the web and the correlation coefficient between the unit wt. of the edge portion and distance frm the edge is 0.55 or more. Pref. the transporter fluid is air, steam or water and fibres are blown against and reflecting impact surface during transport.

    Abstract: A napped sheet has a pattern thereon formed by the sharp contrast between an area with a nap surface and an area with a reversed nap surface on which nap ends are reversed and extend into the inner part of the sheet.A process for producing the sheet includes the steps of first raising a fibre sheet to form naps (2) from the base layer (4). Then a high pressure columnar fluid jet stream is impinged on parts of the fibre sheet to produce recesses (3), causing the naps (2) to be reversed into the base layer (4); if the jet is sufficiently strong, fibres (6) protrude from the reverse side, forming another pattern on the reverse surface.
