The high bulk density flame retardant fiber cotton yarn web and the carbon fiber cotton yarn web, and those production

摘要

PROBLEM TO BE SOLVED: To provide a high bulk density flame-retardant fiber spun yarn woven fabric which is flexible, has an excellent property for passing through a process having the curves of rollers, or the like, and can be stored in a scroll-like shape, and to provide a carbon fiber spun yarn woven fabric which is flexible and thin and has a low electric resistance value in the thickness direction.;SOLUTION: The high bulk density flame-resistance fiber spun yarn woven fabric is characterized by having a flame-resistance fiber content of ≥90 wt.% and a bulk density of 0.6 to 1.1 g/cm³, when a load of 2.8 kPa is added in the thickness direction, and the carbon fiber spun yarn woven fabric is characterized by having a thickness of 0.1 to 0.5 mm, a bending resistance of 5 to 25 mNcm, and a bulk density of 0.35 to 0.6 g/cm³, when a load of 2.8 kPa is added in the thickness direction. Methods for producing these woven fabrics are also provided.;COPYRIGHT: (C)2004,JPO
