Abstract:
Disclosed are a lyocell material for a cigarette filter and a method of preparing the same, wherein a crimped tow is manufactured using a lyocell multifilament including low-strength lyocell monofilaments, and thus the ultimately prepared lyocell material for a cigarette filter can exhibit low strength, thereby increasing processing efficiency during the manufacture of the cigarette filter.
Abstract:
The present invention relates to an airbag including an inflating part having gas inflatability, a non-inflating part supporting the inflating part, a combined part constituting a boundary between the inflating part and the non-inflating part, and an ultrasonic fusion bonded part located between the combined part and the end part of an inflator from which a gas at a high pressure spurts when a car crashes, and a preparation method thereof.
Abstract:
The present invention relates to a lyocell fiber, and more specifically to a lyocell fiber, wherein the cross-sectional shape of a monofilament contained in the lyocell fiber is controlled to thus increase the specific surface area of the fiber, thereby exhibiting properties equal or superior to those of conventional lyocell fibers, even when used in a small amount.
Abstract:
A machine for folding a side curtain airbag which has a simpler machine configuration and is more efficient than a fully automatic machine and that can fold a large-capacity side curtain airbag cushion of approximately 4.0 m in length to sufficiently secure quality stability, and a process for folding a side curtain airbag by using the same, are provided.
Abstract:
Disclosed is a polyester sewing thread usable for a fabric for an airbag and a cushion for an airbag. A polyester sewing thread is obtained by doubling and twisting a specific polyester yarn including a plurality of polyester filaments, and bonding the polyester yarn in the manner of in-bonding, out-bonding, or in-and-out bonding. The polyester fiber has high strength, middle elongation, and dry heat shrinkage, and may be used as sewing threads with excellent physical properties similar to those of a sewing thread of existing polyamide fiber (Nylon 66). A method for producing the thread is also disclosed.
Abstract:
This invention relates to a method of manufacturing a lyocell material for a cigarette filter, including (S1) spinning a lyocell spinning dope composed of 8 to 13 wt % of a cellulose pulp and 87 to 92 wt % of an N-methylmorpholine-N-oxide (NMMO) aqueous solution; (S2) coagulating the lyocell spinning dope spun in (S1), thus obtaining a lyocell multifilament; (S3) water-washing the lyocell multifilament obtained in (S2); (S4) oiling the lyocell multifilament water-washed in (S3); and (S5) applying steam and pressure to the lyocell multifilament obtained in (S4), thus obtaining a crimped tow having 30 to 40 crimps per inch.
Abstract:
This invention relates to a lyocell material for a tobacco filter and a method of manufacturing the same, and more particularly to a lyocell fiber having a modified cross-section for a tobacco filter, wherein the cross-sectional shape of a monofilament contained in a lyocell fiber is controlled to increase the external surface area of the fiber, after which then crimps are formed, thereby exhibiting properties equal or superior to those of conventional lyocell materials, even when used in a small amount.
Abstract:
This invention relates to a lyocell fiber and, more specifically, to a lyocell fiber exhibiting the same or improved physical properties even if used in a lesser amount, compared to a conventional lyocell fiber, by controlling the shape of the section of a monofilament included in the lyocell fiber to increase the specific surface area of the fiber.
