High-precision Yarn Linear Density Testers, also known as Wrap Reel, are available in Manual and Motorized versions, providing versatility and accuracy for determining yarn linear density (also known as yarn count) across a wide range of applications.

Yarn Linear Density Tester (Wrap Reel)

The Yarn Linear Density Tester, utilizing the wrap reel method, is engineered to measure the linear density of yarns accurately. This measurement is critical in assessing the quality, consistency, and performance of yarns used in textiles and industrial fabrics.

Key Features:

• High precision for reliable measurements
• User-friendly interface for easy operation
• Consistent tension and speed control for uniform skeins
• Suitable for various yarn types, including cotton, wool, synthetic fibers, and blends
• Durable construction with high-quality materials

Available Models:

Manual Version: Ideal for small-scale operations and laboratories requiring cost-effective solutions, offering precise control.
Motorized Version: Perfect for high-volume testing environments, providing automation for increased efficiency, consistent winding, and reduced operator fatigue.

Test Method

The linear density (yarn count) is determined using the wrap reel method, where a specified length of yarn is wound onto a reel to form a skein. The skein is conditioned and weighed, and the linear density is calculated based on the weight and length of the yarn.

Steps Involved:

• Preparation: Condition the yarn sample as per standard requirements.
• Winding: Use the Yarn Linear Density Tester (Wrap Reel) to wind the yarn into a skein of defined length and number of turns.
• Weighing: Accurately weigh the skein using a precision balance.
• Calculation: Determine the linear density using the appropriate formula based on the system of measurement (e.g., Tex, Denier, or Cotton Count).

Compliance with International Standards

The Yarn Linear Density Testers (Wrap Reel Models) comply with the following international standards:

• ASTM D1059: Standard Test Method for Yarn Number Based on Short-Length Specimens
• ASTM D1907: Standard Test Method for Linear Density of Yarn (Skein Method)
• ASTM D2260: Standard Test Method for Twist in Yarns by the Single Strand Method
• ISO 7211: Textiles — Methods for Analysis of Woven Fabrics
• ISO 2060: Textiles — Yarn from Packages — Determination of Linear Density (Mass per Unit Length) by the Skein Method
• BS 2010: British Standard for Yarn Count Measurement
