Abstract:
In the present invention, polyvinyl butyral pellets are melt-spun at a temperature lower than 240°C to yield a polyvinyl-butyral-containing fiber having a butyraldehyde content of 20 mass ppm or less. The pellets have a degree of butyralation of 50-90% by mass, an MFR at 150°C and 2.16 kgf of 0.5-45 g/10 min, and an acid value of 0.2 mg KOH/g or less. Obtained thereby is a polyvinyl butyral fiber exhibiting little of the unique odor encountered when handling the fiber, and provided is a laminated article suited for use as upholstery, in which a nonwoven or woven containing the fiber is used as an adhesive layer.
