Polypropylene is the lightest of
all fibers and hence, provides more fiber per pound for greater area
coverage. The fiber has many inherent properties that makes it popular for
fabrics. Different types of polypropelene are manufactured using different
techniques, this in turn leads to creation of different properties. Some of
the common properties are:
- Strength: The range of strength of this
fiber is quite wide and is comparable to that of nylon and polyester.
The fiber also has good abrasion resistance, making it durable and apt
for use in consumer and industrial applications.
- Elasticity: Polypropylene fibers are
less elastic as compared to nylon fibers. Constant stress on the yarn
can result in permanent elongation to a certain extent.
- Resilience: The fiber has good
resilience and is thus very suitable for manufacturing carpets and
apparel. The greater the strength of the fiber, the less resilient it
is.
- Absorbency: The fiber is non absorbent.
The fiber resists soiling, staining and can be easily cleaned. It cannot
be easily dyed or printed.
- Heat Conductivity: Polypropylene has
good insulating properties, which makes it apt for manufacturing
sweaters, blankets, carpets etc.
