摘要： PURPOSE:To make an infusion of tea (tochucha) which is transparent in solution without turbidity and excellent in the appearance and also the feeling of tongue and taste, by constituting a material sheet of tochucha tea bag with a laminate sheet including at least a two-layer non-woven cloth. CONSTITUTION:A material sheet of tochucha tea bags having the front face layer and the rear face layer is constituted of a laminate sheet including at least a two-layer non-woven cloth. The rear face layer is made of a thermoplastic non-woven fiber cloth and the front face layer is made of a non-woven cloth which is not melted even in a higher temperature by 30 deg.C than the melting point. And at least one layer is formed from the laminate sheet including a non-woven cloth made of extremely finer fibers than 10 micron in the mean diameter and tochucha tea is charged in the laminate sheet. The resistance of water pressure of the laminate sheet measured on the basis of JIS L-1092 A method is specified to be 100mm or lower. And time mean diameter of pierced holes measured by ASTM F316-86 standard bubble point method is specified to be 15-25 micron m.

摘要： PROBLEM TO BE SOLVED: To obtain a durability in view point of anti-slipping effects and reduce the cost of a base fabric by a method wherein a melt blown non-woven fabric, which is made of an elastic polymer through a polypropylene spun-bound non- woven fabric and has a specified average fiber diameter, is pasted onto the rear surface of a needle punched non-woven fabric. SOLUTION: The excellent anti-slipping effects of a melt blown (henceforth expressed as MB) non-woven fabric, which is made of an elastic polymer and has an average fiber diameter of 20 μm or less, is utilized. In order to apply the above effects to the slip-proofing of a secondary base fabric made of a needle punched non-woven fabric 1, a polypropylene (henceforth expressed as PP) spun-bound non-woven fabric is punched together onto the rear surface of the needle punched non-woven fabric 1 during its manufacturing process into an integral body. By bonding with a heated projected roll under heat and pressure from the MB non-woven fabric side under the state that the MB non- woven fabric is put on this PP spun-bound side, these layers are fusedly bonded together under heat. Accordingly, the resultant fabric has the extremely excellent and durable anti-slipping effects and can be easily manufactured and provided at a low cost.

摘要： PURPOSE:To uniformly dye a fabric to a dark color without fluff disturbance on the surface thereof and reduction in strength in a simple step by applying an aqueous solution containing a water-soluble vat dye to a nonwoven fabric composed of hydrophilic fiber and then irradiating the resultant fabric with ultraviolet rays. CONSTITUTION:An aqueous solution containing a water-soluble vat dye is applied to a nonwoven fabric (e.g. rayon nonwoven fabric) composed of hydrophilic fiber and the resultant fabric in a tensionless wet extended fabric state is subsequently irradiated with ultraviolet rays (at 360-370nm wavelength) to color and dye the aforementioned nonwoven fabric therewith. Thereby, the objective dyed fabric of a dark color can be readily obtained in a simple step with excellent coloring properties and dyeability without unevenness, disturbance of surface fluffs on the surface thereof and reduction in strength according to the above-mentioned method.

摘要： PROBLEM TO BE SOLVED: To sufficiently prevent discoloration of clothing by ultraviolet rays by using melt blown nonwoven fabric, which is formed by performing melt blown spinning on polypropylene by kneading titanium oxide having a specific particle size distribution and has an ultraviolet ray shielding rate not less than a spacific value, at least for one surface of obverse/reverse two surfaces as a sheet-like material. SOLUTION: Melt blown(MB) nonwoven fabric is used as a raw material of a clothing cover 1. The MB nonwoven fabric can be manufactured by using either of thermoplastic polymers, but is most desirably formed as MB nonwoven fabric using polypropylene. Many materials such as titanium oxide, silica and alumina are known as inorganic particulates, but titanium oxide having a particle size distribution of 0.1 to 2.0 μm is desirable as inorganic particulates kneaded in an MB polymer when aiming at shielding of ultraviolet rays, and its kneading quantity is set to 1 to 5%, and an ultraviolet ray shielding rate of the nonwoven fabric is set not less than 50%, and is desirably set not less than 65%, and is most desirable as compared with the other inorganic particulates.

摘要： PROBLEM TO BE SOLVED: To enable a process in which a precursor sheet is manufactured simply with good operability by a method in which a polymer film layer and a nonwoven fabric layer are laminated in a nonstretching state on a cooling molding part, the laminate is cooled, and in both end parts of the breadth direction, both layers are cemented in the longitudinal direction. SOLUTION: An expandable/shrinkable polymer film (a) discharged from a die 1 is laid for example with a nonwoven fabric (b) which is expandable in the cross direction to overlap a cooling molding part which is formed by a cooling roll 2 and a nip roll 3 to be introduced so that the film (a) layer comes to the side of the roll 2 and the fabric (b) layer comes to the side of the roll 3. In the cooling molding part, both end parts in the breadth direction of the roll 3 are pressed by two protruding belts which are installed in both end parts to surround the whole peripheral surface, the film (a) layer, which is still kept adhesive, is cemented to the fabric (b) layer in both end parts in the breadth direction, and the inside part between the protruding belts is made nonadhesive.
