Why Polypropylene ?
Polypropylene, a synthetic resin built up by the polymerization of propylene, is molded or extruded into many plastic products in which toughness, flexibility, light weight, and heat resistance are required. It can be spun into fibres for employment in industrial and household textiles.
The polymer shares some of the properties of polyethylene, but it is stronger, stiffer, and harder, and it softens at higher temperatures.
A large proportion of polypropylene production is melt-spun into fibres. Polypropylene fibre is a major option in home furnishings such as upholstery and indoor-outdoor carpets. Numerous industrial end uses exist as well, including fishing gears, rope and cordage, disposable nonwoven fabrics for diapers and medical applications, and nonwoven fabrics for ground stabilization and reinforcement in construction and road paving. These applications take advantage of the toughness, resilience, water resistance, and chemical inertness of the polymer.

Polypropylene is a linear hydrocarbon polymer compound, no
benzene ring in the chemical formula, is eventually decomposed to water and carbon dioxide (CO2) in the case of anaerobic conditions, vapor no harmful and hazardous component during degradation and landfill incineration.
GLOBAL RECOGNITION OF ENVIRONMENTAL PROPERTIES OF POLYPROPYLENE IS ASCERTAINED.
THE NATURE OF HYDROCARBON POLYMER COMPOUND AND LOW MELTING POINT MAKE IT ENERGY SAVING AND FREE OF TOXIC.
THE HYDROPHOBIC QUALITY CAN BE TAKEN ADVANTAGE TO ENHANCE LONG - LASTING REPELLENCY.
Low Carbon Footprint Polypropylene
ISO 14067 specifies the principles, requirements and guidelines for the quantification and reporting of the carbon footprint of a product. A recent audit of nylon, polyester, and polypropylene yarn in the same form of texturing at the same production site concludes the following verifed data, which indicates that polypropylene is the lowest carbon footprint among the three synthetic fibers.
The Higg Index is a suite of tools for the standardized measurement of value chain sustainability. Below MSI scores of nylon, polyester, and polypropylene fabric in 135 denier & processing condition (solution-dyed) are retrieved from Material Sustainable Index (MSI) platform that shows polypropylene fabric generates the lowest impact of each five differnet environmental index.

Comparison of Olefin and other fibers
Polypropylene is lighter than water, so it is considered the best for fishing gear, marine and nautical wear.
Polypropylene is the lowest thermal conductivity. It maintains heat and keep warm, so it is considered the best for thermal underwear and mid layer.
Polypropylene is low water content and low moisture regain. Bacteria can hardly grow and doesn't generate odor. it's great for outdoor sport wear.
Polypropylene absorb minimum water in the rain which allow the textile to air dry quickly. it's great for outdoor patio furniture and water sport wear.
