Properties of Polypropylene
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.
