Precision Yarn Wrapping Machine for Accurate Yarn Linear Density Testing

The Yarn Linear Density Tester, also known as a wrap reel machine, is a critical instrument for measuring yarn linear density in both laboratory and production settings. This versatile tester is available in manual and motorized models, offering flexibility for small-scale use and high-throughput operations alike.

Using the wrap reel method, the tester winds a defined length of yarn into uniform skeins, enabling precise calculation of linear density, also referred to as yarn count. This process is essential for quality control and standardization in the production of textiles, industrial fabrics, and fiber-based products.

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.

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)

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).
