Polypropylene yarn type and characteristics

  Polypropylene yarn :

Propylene is a by-product of petroleum. During the polymerization of propylene gas with the addition of liquid metal and in a state of under controlled polymerization this fiber is produced. Titanium chloride is a liquid metal that is used to polymerize. Polypropylene is made by melt spinning and this is the easiest spinning process. 

Types of propylene yarn : 

This kind of fiber has a variety of forms and a wide range of diameters. Some are white that can be dyed and some have pigments that are not dye-able. Some are bright, some are dull and some have more prevent power to light and some have more tolerability of heat. 

There are 5 types of propylene fiber. 

1. Monofilament yarn 

2.Multifilament yarn 

3.Fibrilated yarn 

4.Spun yarn 

5.Textured yarn 

1. Monofilament yarn : 

From different filaments, we can make monofilament yarn. This type of yarn has a greater range from 150 deniers to 10,000 deniers. 

2. Multifilament  yarn :

In multifilament yarn, there is more filament in the yarn. Here we can find 34 to 420 pcs filament. Available are 60 deniers to 4500 deniers. 

3. Fibrillated yarn : 

If we cut a polypropylene sheet and twist it with monofilament then it is called fibrillated yarn. 

4. Spun yarn: If we make polypropylene fiber in a staple length we can use that to make no woven fabric. Also can be possible to make the yarn as cotton or wool by spinning. 

5. Textured yarn: Multifilament polypropylene fiber can be textured or crimped. These crimped filaments are thrown and make yarn. 

Polypropylene fiber characteristics :

1.    This fiber has a circular or elliptical cross-section.

2.    This fiber is not white.

3.    Tenacity is 3.5-8.

4.    Viscosity:0.91.

5.    Stretch and elasticity are good.

6.    Resiliency is good.

7.    Abrasion resistance is good.

8.    Moisture regain 0.1%

9.    Melting point is 170 degrees centigrade

10. Moderate heat conductivity.
