Sweating Guarded Hotplate Testing Materials
There are 3 ways for moisture penetrating
fabrics:
1. Vapor spreads through fabric microporous;
2. Fiber absorbs moisture and flows out from the
place where water pressure is lower;
3. Large amount of water molecule creates dew and
spreads through capillary and evaporates at a place where water pressure is
lower.

The Vapor amount generated from absorption, transfer
and flowing out is related to fiber, moisture absorption amount, expansion
degree, fiber pores and channels.
The textile products of sweating guarded hotplate
test should be water absorption and quicksetness. Polyester has high
crystallinity molecular chain structure, thus ensures polyester these features
such as small amount of water absorption and bad air permeability which stands
out definitely in the feature of quicksetness. Natural fiber like cotton is
endowed with many holes which make it good at water absorption, but the
expansion results in water gripping and poor quicksetness.
Generally speaking, hydroscopic and sweat fiber
tested for sweating guarded hotplate uses capillarity generated from fine
groove to make sweat volatilized quickly. For more sweating guarded hotplate
test and textile testing instruments, contact QINSUN Instruments.
