Is Silk a Filament Yarn?

Published in Textile Fibers 2 mins read

Yes, reeled silk yarn is considered a filament yarn. This is a key characteristic that defines its properties and uses in textiles.

Understanding Filament Yarn

Filament yarn is made up of continuous strands of fibers, as opposed to spun yarn, which is made from short, staple fibers twisted together. These continuous filaments are typically very long, often measured in kilometers.

Why Reeled Silk is a Filament Yarn

According to the provided reference on Reeled Silk Yarn:

  • It is described as the "Purest form of silk yarn, also known as filament yarn."
  • It is "Composed of very long filaments that make it incredibly strong."

This explicitly states that reeled silk yarn falls under the category of filament yarn due to its composition of naturally long, continuous silk filaments.

Characteristics of Silk Filament Yarn

The nature of reeled silk as a filament yarn contributes to its desirable qualities:

  • Strength: The very long, continuous filaments contribute to high tensile strength.
  • Smoothness and Luster: Unlike spun yarns which have fiber ends that can protrude, filament yarns like silk are smooth, leading to a lustrous surface.
  • Lightweight: Despite its strength, silk is a lightweight fiber.
  • Quality: Reeled silk yarn is often considered the highest quality lightweight silk yarn.

Popular Uses

Based on its characteristics as a high-quality filament yarn, reeled silk is popularly used for:

  • Fine and luxury apparel
  • Items like sari silk yarn

These applications benefit from the strength, smoothness, drape, and aesthetic appeal that silk filament yarn provides.
