Abstract
A thread has a thread body formed of a continuous and monolithic synthetic resin material. The thread body defines chambers serially disposed along a length of the thread body and separated from one another by partitions. A gas, which may be lighter than air, fills the chambers. An embodiment has the chambers as radially adjacent chambers dispose along two to four radially adjacent longitudinal sectors of the thread body. The partitions of the two to four sectors are disposed either at common longitudinal locations or offset locations. The thread may be used as a fishing line that floats or in survival equipment wherein buoyancy is enhance. Still further, the thread provides for enhanced thermal insulation when used to weave a cloth.
