Doubling
UTWF
Doubling Process in UTWF Essential Step for Yarn Strength and Quality
The doubling process in the textile industry is a crucial step in yarn manufacturing that involves combining two or more single yarns to create a stronger, smoother, and more uniform final product. This process enhances the properties of the yarn, making it more suitable for various textile applications, including weaving, knitting, and sewing.
Objectives of the Doubling Process
✔ Increase Yarn Strength – Combined yarns have higher tensile strength than single yarns.
✔ Improve Uniformity – Helps in reducing variations in thickness and texture.
✔ Enhance Smoothness – Reduces hairiness and makes the yarn surface smoother.
✔ Reduce Imperfections – Eliminates weak points, making the yarn more durable.
✔ Improve Appearance & Performance – Suitable for high-quality fabrics with better drape and feel.
Types of Doubling in Textiles
1️⃣ Parallel Doubling – Yarns are combined without additional twist, mainly for blending purposes.
2️⃣ Twisted Doubling (Plying) – Yarns are twisted together to improve strength and elasticity.
3️⃣ Cable Doubling – Multiple plied yarns are further twisted to create complex, high-strength yarns.
Machines Used in the Doubling Process
- Doubling Frame Machine – Used to combine yarns before twisting.
- Ring Doubling Machine – Twists the yarns together for better cohesion.
- Two-for-One Twister (TFO Machine) – Efficiently twists yarns with higher productivity.
- Assembly Winder – Prepares yarns for doubling by aligning them properly.
Applications of Doubled Yarn
- Apparel Textiles – Used in fine-quality fabrics for shirts, suits, and dresses.
- Industrial Textiles – Strengthened yarns for ropes, nets, and tire cords.
- Knitting & Hosiery – Ensures uniformity in stretchable garments.
- Embroidery Threads – Enhances durability and sheen.
