摘要： Provided is a fiber having an elongated, unsupported, three-dimensional fiber body with a fiber body length and at least one fiber material disposed along the fiber body length. The at least one fiber material has a viscosity lower than about 108 Poise at a common thermal fiber draw temperature. At least one topological pattern is disposed on at least one surface of the fiber body and extends longitudinally along at least a portion of the fiber body length. To form the fiber, there is assembled a fiber preform including at least one preform material. A surface of at least one preform material is patterned and arranged as a fiber preform surface, providing a topological pattern on a fiber preform surface. The fiber preform is thermally drawn into an elongated fiber at a fiber draw temperature at which all preform materials have a viscosity lower than about 108 Poise.

摘要： A polymeric fiber for use in gas separation is formed from a spin dope which includes solvent and non-solvent materials. The fiber is passed through a quench bath, and then a leach bath, in which the solvent and non-solvent are removed. The quench bath and the leach bath include sets of rollers which transport the fiber through the system. Each set of rollers in the leach bath operates at a speed which is greater than or equal to the speed of the rollers which are immediately upstream. Thus, the fiber is stretched, in different amounts, at the same time that the solvent and non-solvent are being removed, and while the fiber is still wet. The resulting fiber has been found to exhibit superior flux and selectivity properties.

摘要： A needle blade roll (12) for forming short fibers from a material capable of formation of artificial cotton in an artificial cotton fabricating apparatus is disclosed which is made up of a roll main body (13) and a large number of needle blades (14) implanted into a peripheral surface of the roll main body (13). In the needle blade roll (12), each needle blade (14) is arranged at a sloping angle relative to a radial line of the roll main body (13) so that its leading end lies ahead of the radial line with respect to the rotational direction of the roll main body (13). This makes it possible to form short fibers the length of which is longer than conventional, thereby fabricating artificial cotton made of such short fibers which are fully intertwined with one another.

摘要： Disclosed is a method of producing a polyethylene terephthalate-based polyester fiber, including spinning polyethylene terephthalate based polyester to produce an undrawn yarn with an intrinsic viscosity of 0.83 or more and a density of 1.338 g/cm3 or more, multi-stage drawing the undrawn yarn, heat-setting the drawn yarn, relaxing the heat-set yarn, and winding the relaxed yarn to produce the resulting drawn yarn with an intrinsic viscosity of 0.83 or more and a density of 1.38 to 1.3865 g/cm3. Compared to a prior polyester yarn with high modulus and low shrinkage, produced according to conventional melt-spinning and drawing processes, an industrial polyester yarn with high modulus and low shrinkage according to the present invention contributes to significantly improving strength retention (tenacity of a dip cord/tenacity of a grey yarn) of the dip cord, produced by treating the polyester yarn of the present invention with an adhesive (RFL) and subsequently heat-treating the RFL-treated polyester yarn. Therefore, the polyester multifilament yarn according to the present invention is useful as a tire cord.

摘要： Disclosed is a vacuum packaging film having a multiple of groups of protuberances, a method of manufacturing the same and a vacuum packaging bag using the same. The vacuum packaging film includes a base layer, and a thermoforming layer laminated on the base layer and having protuberances on an inner surface thereof to form air passages, in which the protuberances have first group of protuberances, second group of protuberances having a height higher than that of the first group of protuberances, third group of protuberances having a height higher than that of the second group of protuberances, and fourth group of protuberances having a height higher than that of the third group of protuberances. Further, the four groups of protuberances have different arrangements arranged at different angles, thus clearly showing a pattern formed on an inner surface of the thermoforming layer. Also, since the vacuum packaging film has two to four groups of protuberances, a total surface area of the protuberances is enlarged. Thereby, an output flux of air increases and an internal chamber of the vacuum packaging bag can be easily made to the state of vacuum. Furthermore, a variety of patterns can be formed by various sizes and different arrangement directions of the protuberances, therefore resulting in increased productivity of end products according the needs of users.
