The present invention relates to a method for producing a nonwoven fabric which improves the impregnation property of a fabric softener in the nonwoven fabric so as to apply the nonwoven fabric to a dryer sheet (sheet type fabric softener). As the impregnation property of a fabric softener is improved even when a nonwoven fabric is made lightweight, by increasing the porosity in the nonwoven fabric made of polyester filaments having two components mixed therein, widening the specific surface area, and controlling uniformity deviation to be small, the nonwoven fabric can be applied to a dryer sheet.
The present disclosure relates to a nonwoven fabric having enhanced withdrawal force for a carpet backing fabric, which is composed of a nonwoven fabric comprising 50 to 90% by weight of polyester filaments having a melting point of 250°C or higher and 10 to 50% by weight of low-melting point copolyester filaments having a melting point of 200°C or lower. According to the present disclosure, a nonwoven fabric comprising low-melting point polyester fibers is used as a backing fabric and the thickness of the backing fabric is controlled, so that the withdrawal force of carpets is enhanced, thereby suppressing the falling out of BCF yarns from the carpet.
Technologies directed to a hollow fiber membrane cartridge-type humidification module are described. The module includes a housing; hollow fiber membrane cartridges fitted to ends of hollow fiber membrane bundles, which are inserted into the housing; a sectioning unit provided inside the housing to section the hollow fiber membrane bundles; and a potting portion to fix both the hollow fiber membrane cartridges and the hollow fiber membrane bundles in the housing. Ends of the hollow fiber membrane cartridges are inserted in respective insertion spaces inside the sectioning unit. The described technologies enable fabrication of a housing according to the type and number of the commonly used hollow fiber membrane cartridges and can be expanded to products with various capacities, efficiency can be improved given the type, number, and size ratio of the hollow fiber membrane cartridges, and simple potting can reduce the manufacturing time and cost.

BULLETPROOF FABRIC AND BODY ARMOR MANUFACTURED BY USING SAME
The present invention discloses a bulletproof fabric and a body armor manufactured using the same. The bulletproof fabric includes an aramid fabric 10 including wholly aromatic polyamide multifilaments as warps and wefts, a primary water-repellent coating layer 20 formed on the aramid fabric 10, and a secondary water-repellent coating layer 30 formed on the primary water-repellent coating layer 20. The body armor of the present invention has a laminate structure of stacking up 10 to 50 sheets of the above bulletproof fabrics, preferably, further includes an aramid composite pad 40 inserted in a pocket provided at a part of the body armor. According to the present invention, water-repellent properties are excellent to noticeably improve bulletproof performance in a wet state, and specifically, when the body armor has the aramid composite pad 40 inserted therein, rear deformation of the body armor after the bulletproof performance test is considerably reduced.

A BRAID-REINFORCED COMPOSITE HOLLOW FIBER MEMBRANE
A braid-reinforced composite hollow fiber membrane is disclosed. The braid- reinforced composite hollow fiber membrane comprising a reinforcing material of a tubular braid and a polymer resinous thin film coated on the surface of the tubular braid is characterized in that: the tubular braid comprises multifilaments made of monofilaments having a fineness of 0.01 to 0.4 denier, and the peeling strength of the tubular braid and a polymer resinous thin film coated on the surface thereof is 1 to 10 MPa. In the composite hollow fiber membrane, the fineness of the monofilaments constituting the tubular braid of the reinforcing material is small, that is, 0.01 to 0.4 denier, thus the surface area of the tubular braid contacted with the polymer resinous thin film is increased. Thus, the peeling strength of the tubular braid and the polymer resinous thin film coated on the surface thereof is excellent, and at the same time, the initial wetting property of the composite hollow fiber membrane is excellent, that is, 80 to 120%, due to a capillary tube phenomenon or the like.
