TH31901B - Favorite fiber combined with water - Google Patents

Abstract

DC60 (25/05/43) The fiber that likes to combine with water is a fiber that has The ratio of the polyolefin-capped perimeter to the total perimeter. of the fiber cross-section is 30% or more. and the water-like properties of the fibers are 30 s and below. and the preservation of properties that Prefers to combine with the water of the fiber that over time is 90% or higher. and after treatment at 40 degrees Celsius. and a relative humidity of 80% at a period of 30 days that has also been established. The hydrophilic properties of the fibers were measured according to the following methods. The inner part of the tube made of polymethyl methacrylate and with an internal diameter of 25 mm and an outer diameter of 30 mm and a length of 25 mm of the tube is packed with 5.0 g of fiber. In order not to protrude the fibers, the tubes were floated on 1,000 cc of soft water at 30 degrees Celsius. In a medium-diameter container, the set is empty 105 mm and is filled with water. It is left and settled immediately to the bottom of the container. The fibers are then removed from the inside of the pipe. and air-dried at normal temperature. The operation was repeated four times. and the number of seconds required for the pipe to float on the water. Until it sinks to the bottom, the container will be measured next. in doing the fifth To obtain the water-loving properties of the fibers, the fibers that prefer to combine with the water-containing fibers The ratio of the polyolefin-capped perimeter to the total perimeter. of the fiber cross-section is 30% or more. and the water-like properties of the fibers are 30 s and below. and the preservation of properties that Prefers to combine with the water of the fiber that over time is 90% or higher. and after treatment at a temperature of 40 °C and relative humidity of 80% at a period of time after 30 days has also been established. The hydrophilic properties of the fibers were measured according to the following methods: the inner part of the pipe made of polymethyl methacrylate and with an internal diameter of 25 mm and an outer diameter of 30. 25 mm and 25 mm tubes are packed with 5.0 g of fiber to avoid protrusion of the fibers. It has a diameter - 105 mm in diameter and is filled with water. was left and The sediment immediately settles to the bottom of the container. The fiber is then removed from the inside of the tube. and air-dried at normal temperature. The operation was repeated four times. and the number of seconds required for the pipe to float on the water. Until it sinks to the bottom, the container will be measured afterwards. in doing the fifth To obtain the water-loving properties of fibers:
