ADVANTAGES OF POLYPROPYLENE FIBERS, DISADVANTAGES OF POLYPROPYLENE FIBERS

ADVANTAGES OF POLYPROPYLENE FIBERS:

• The polypropylene fibre  poses very good resistance against the most of the acids and alkali. 

• It doesn't absorb the moisture. The properties of the polypropylene fibre  remain unchanged in wet and dry conditions due to zero moisture absorbency.

•The low moisture regain helps in quick transport of moisture required in special applications like babies ever-dry nappies.

• The polypropylene is a light fibre, its density (0.91 grammes/cubic centimeter) is the lowest of all synthetic fibres.

• The  polypropylene fibre poses lower thermal conductivity than other fibres. This nature of polypropylene allows users to  use it for applications as thermal wear.

DISADVANTAGES OF POLYPROPYLENE FIBRES:

The main demerits of polypropylene  fibres are given below:

•  The polypropylene fibre poses poor ultra-violet  and thermal stability .

• The  polypropylene fibre has low melting point . This demerit doesn't allow ironing of polypropylene fabrics.

• It is very difficult to be dyed after manufacturing.  Proper  dyeing of it is possible  after substantial treatment and modification.

• It  has High crystallinity and poor thermal conductivity. This demerit of polypropylene doesn't allow   proper texturizing of it.

• It shows poor adhesion to glues and latex.

• It begins to Creep due to its low glass transition temperature (15 °C to -20°C).

•  It is flammable which melts and burns like wax.

• It has poor resilience in comparison  to polyester and Nylon,
