The polypropylene nonwoven fabric produced by the method for producing a polypropylene nonwoven fabric according to the present invention has features that it has excellent stretchability and excellent water pressure resistance.

Method for producing polypropylene nonwoven fabric

The present disclosure relates to a polypropylene for injection having a high content of ultra-high molecular weight and excellent rigidity, and a method for preparing the same.

Polypropylene and method for preparing the same

The present invention provides a resin composition for core-sheath type bi-component fiber that not only maintains excellent softness, but also improves tensile strength, when preparing non-woven fabric, particularly spunbond non-woven fabric.

Resin composition for bi-component fiber

The present invention provides a homopolypropylene having high strength and a low content of low molecular weights together with excellent processability, and a preparation method thereof.

Provided is a propylene random copolymer having excellent processability. The propylene random copolymer according to the present invention may exhibit high stiffness and flexural modulus together with a low shrinkage ratio, thereby being usefully applied to articles for thin wall injection molding.

Propylene random copolymer

A homopolypropylene has i) a molecular weight distribution of less than 2.4; ii) a melt index (measured at 230&#xb0; C. under a load of 2.16 kg in accordance with ASTM D1238) of 5 to 3000 g/10 min; iii) a remaining stress ratio of 0.5% or less; and iv) a complex viscosity of 5 to 600 Pa&#xb7;s at an angular frequency of 1 rad/s and a complex viscosity of 5 to 300 Pa&#xb7;s at an angular frequency of 100 rad/s. A method for preparing the homopolyproylene is also provided. A molded article and a non-woven fabric are also provided.

Homopolypropylene and method for preparing the same

A railway installation monitoring system may include: a laser generator that is provided on a train; a camera that is operated in connection with the laser generator so as to be capable of monitoring a railway installation and of acquiring image information data that is measured; a three-dimensional image information conversion device that uses the image information data acquired by the laser generator and the camera and converts the data into three-dimensional image information; a position determination unit that determines the position of the railway installation to be measured; a signal processing device that sends an operating command for the laser generator or/and the camera; and an overall data processing device that processes, analyzes, interprets, or stores the image information data, the three-dimensional image information, or the data transmitted from the position determination unit.
