Difference Between Polyester and Polypropylene Cord

Difference Between Polyester and Polypropylene Cord

Customers of Fofanov Y. S. PE often ask: What is the difference between polyester and polypropylene cord?

In this article, we explain the key differences, features, pros and cons of both materials.

A Crafter’s Opinion on the Difference

Polypropylene cord is like acrylic, while polyester feels like wool.

Polypropylene is shiny, slippery, and squeaks unpleasantly when crocheting.

Polyester is incredibly soft and pleasant to the touch — almost like a natural fiber. It is elastic, springy, and holds its shape well. Finished products look plush, voluminous, and do not fade, attract dust, or build up static.

Minor downside: if the cord’s end is pulled, it may unravel. But if you slightly melt the tip, it seals off and won’t unravel again.

Polyester Cord

Key Features of Polyester

• High strength and durability

• Wrinkle-resistant and fade-resistant

• Elastic and shape-retaining

• Hypoallergenic

• Easy care (quick drying, easy washing)

• Antibacterial properties

• UV, heat, and weather resistant

Benefits of Polyester Yarn

• Soft and comfortable touch

• Anti-pilling (doesn’t fuzz)

• Rich, long-lasting colors

• Keeps its appearance over time

• Resistant to solvents and abrasion

Technical Overview of Polyester

Polyester fibers are made by melting polyethylene terephthalate — a product of petroleum refining. Common brand names include Lavsan, Dacron, Terylene, Tergal, and Tesil.

Properties of Polyester Fiber:

• Excellent thermal resistance

• Shape retention and low shrinkage

• Resistant to mold, bacteria, and insects

• Low moisture absorption, retains shape even when wet

• Long service life in various environmental conditions

Polypropylene Cord

Benefits of Polypropylene

• High wear resistance

• Resistant to aggressive environments (acids, bases, solvents)

• Often made from recycled materials

• Low cost

• Floats in water (lighter than water)

Characteristics of Polypropylene Fiber

• Very lightweight

• Moderate mechanical strength

• Moderate thermal resistance

• Sensitive to UV light (UV stabilizers needed)

• May react with certain solvents and oxidizers

Drawbacks

• Weakens at 90–160°C; melting point around 160°C

• Poor UV resistance without additives

• Cannot be bleached or cleaned with aggressive chemicals
