Abstract: The present invention provides a method for industrially stably producing a stretched polyamide film having uniform properties at a high speed. The polyamide film production method comprises the steps of: extruding a molten polyamide resin from a die into a sheet form on a rotary cooling roll having a roughened surface; pressing the sheet against the surface of the cooling roll with an air layer being present between the cooling roll and the sheet by blowing air onto the sheet from an air knife apparatus for cooling the sheet, the air layer having a widthwise thickness distribution such that an average air layer thickness Te in lateral edge regions of the sheet is greater than an average air layer thickness Tc in a middle region of the sheet; and biaxially stretching the sheet.

Abstract: NOVEL 2,4,6-TRISUBSTITUTED-S-TRIAZINE DERIVATIVES CONTAINING SULFONATE GROUPS ARE USED TO IMPROVE THE DYEABILITY OF SYNTHETIC LINEAR POLYAMIDES, WHEREBY THE DYEABILITY OF THE POLYAMIDES BY BASIC DYESTUFFS IS ENHANCED, WHILE AT THE SAME TIME THE DYEABILITY BY ACID DYESTUFFS IS INHIBITED. THE S-TRAIZINES ARE INCORPORATED IN THE POLYMIDE BY ADDING THEM TO EITHER A POLYAMIDE-FORMING REACTANT OR DIRECTLY TO THE SYNTHETIC LINEAR POLYAMIDE. THE MODIFIED POLYAMIDE CAN BE FURTHER PROCESSED IN THE CONVENTIONAL MANNER.

Abstract: A method of supplying weft yarns includes the steps of holding the free end of a predetermined length of yarn to be used for a weft yarn by suction and a portion of its length near the end along a fluid flow path and supplying the held yarn into the shed by means of a yarn carrier which grips the yarn end and traverses the shed. The apparatus for accomplishing the method includes a reserve pipe into which a predetermined length of yarn is placed from a supply and held for insertion into the shed and a fluid ejector to feed the free end of the yarn to a suction holding device across the path of the weft yarn carrier. The carrier is provided with a gripper for holding the free end of the weft yarn as the carrier is flown across the shed with the ejector assisting in the weft yarn feed.

Abstract: A water purification cartridge includes a casing with a tubular shape that has an inflow portion for raw water to flow in and an outflow portion for purified water to flow out, and a filter member for filtering the raw water, the filter member being accommodating within the casing. The filter member is formed to have a cylindrical shape having a hollow portion, and has a first face and a second face at respective ends in an axial direction. The casing has a first cover portion, a second cover portion, and a side wall portion. The first cover portion covers the first face. The second cover covers the second face. The side wall portion covers an outer circumferential face of the filter member. In the first cover portion, a first contact portion is formed that annularly comes into contact with the first face and that press the filter member in the axial direction to elastically deform the filter member. In the second cover portion, a second contact portion is formed that annularly comes into contact with the second face and that press the filter member in the axial direction to elastically deform the filter member.
