Hindustan Composites Ltd. Manufactures asbestos yarns in a wide
range of constructions with a wide range of properties dependent
on the various applications intended. However, they are
commercially distinguished under the following groups:
A) Nonmetallic.
B) Metallic-incorporating metal wire.
C) Union-in combination with cotton threads.
The size, diameter, or "count" of a yarn can be expressed in many
ways. The modern international method used is the TEX system. The
"TEX NUMBER" indicates the weight of yarn in grams per KM. of
length.
Several ends of yarns can be twisted or braided to produce the
yarn or rope of a higher diameter. The yarn can be reinforced with
ductile metal wire such as brass, copper, zinc, lead, inconel,
monel, stainless steel, etc. Reinforcement with filaments of metal
wire offers particular properties in the end product such as heat
dissipation, high temperature resistance, strength retention or
particular friction properties. It can also be spun in combination
with cotton or yarns made with man-made fibres to give an added
advantage of higher strength and flexibility in lower temperature
applications.
Asbestos yarn can also be treated with high quality lubricants,
oil resisting compounds, PTFE and coated with flake graphite or
mica for specific applications.
