A cladding material for plastic optical fibers is disclosed. The cladding material comprises mainly a copolymer comprising a fluoroalkyl methacrylate and an N-aliphatic maleimide as monomer units. The cladding material has low refractive index and high thermal stability, so that an optical fiber with a large acceptance angle can be obtained.

Cladding material for optical fiber and method for its manufacture

An optical fiber of a sheath-core structure is disclosed. The fiber has for its core a copolymer which includes an aliphatic N-substituted maleimide as a monomer unit, and preferably methyl methacrylate as an additional monomer unit. These optical fibers have high light transmittance, good mechanical characteristics and an excellent heat-resisting durability.

Heat resisting plastic optical fiber and method for its manufacture

A fabric containing a cellulosic fiber and a polyester fiber having a carbonization burning mechanism, superior in flame-proofness and having a soft touch. The fabric contains a halogen- and/or phosphorus-based flame-proofing agent, and preferably also contains an amino resin.
