Cotton
industrial canvas is designed to meet different demands, they are widely
applied in rubber/tyre production, vamp and as filter cloth.
YANPAl is specialized in offering cotton base cloth for card clothing,
which require extra less deformation and high strength. Surface coating,
cement dipping and dyed products available up to demands.
Its
mightiness is a little lower than polyester, the intention is only 352-572
cndtex, the splitting and elongation is 12%-15%, but it possesses the
virtue of a long-time everlasting using and one of the virtue is it has
a good aldalinity-resisting, it can be combined with rubber easily. So
it is the best material for the field of rubber. As for its disadvantage
is it has a bad heat-resisting, it will shrink when the temperature reach
100◦C, the acidresisting is bad.
Polyvinyl
fiber fiber filter-cloth are widly used in the industry of rubber.
Polypropylene
fiber can be divided into short polypropylene fiber and long polypropylene
fiber. The yarns which are made of long polypropylene, fiber are very
slippery. So the bursting strength and gas permeability of the long
polypropylene are much better than that of the short poly-fiber.
Having
the feature of good heat resistance, it can be used at temperature of 280
°C over a long period of time. Applications: It is widely used in the
dust removal and environment protection and in the recovery of useful rare
met.
Its
mightiness are much stronger than any other fibers, the intensity is 4-5.3
Cndtex, splitting and elongation is 18%-45%. So it is suitable for
manufacturing car tyres. Polyemide fiber industry cloth can be
divided into 301#, 407#, 663#, 17-2#, 17-7#, all of them are used in the
industry of pottery medicine, food, metallurgy, rubber, etc. But 66 of
Polyemide fiber filter- cloth can’ t be suit for the fields of medicine
and food, as it is poisonous and it is harmful to people’ s health.
The
filter cloth of polyester fiber in our factory has the feature of
resisting acid, resisting wear and tear, has the feature of high
efficiency of filteration,fast filteration there are many kinds ofthem,and
it can be used in the fields of Food, chemical, deystuff,etc.
