Yarn length measuring machine, hundred meter winding machine, yarn count detection textile instrument, length measuring instrument

A yarn length measuring machine (also known as a yarn length measuring instrument) is a specialized testing instrument used to determine the linear density (fineness) of yarns, fiber filaments, and other materials. It can also prepare samples for yarn strength testing. Its core function is to wind yarn of a set length, calculate the linear density index of the yarn (such as Tex, Denier, etc.) by weighing, and meet the requirements of domestic and foreign standards for yarn quality inspection.

1、 Working principle

Mechanical structure:

Yarn frame: Hexagonal diamond shaped structure, winding yarn by rotation.

Tension system: including tensioners and tension adjusters, ensuring yarn winding uniformity by adjusting yarn tension.

Horizontal yarn arranging device: arranges the yarn in an orderly manner on the yarn frame, avoiding overlap or gaps.

Yarn guide: guides the path of yarn from the sample tube to the yarn frame.

Transmission system: driven by a motor to rotate the yarn frame, supporting stepless speed regulation.

Operation process:

Set the number of yarn loops and tension value.

Start the instrument, rotate the yarn frame and automatically count. After reaching the set number of turns, slowly start and stop to avoid punching.

After winding the yarn, weigh it and calculate the line density based on the number of turns and the length of the turns.

2、 Characteristics

High precision and stability:

Accurate circle counting ensures the reliability of length measurement.

Stepless speed regulation and slow start/stop function reduce the risk of yarn breakage.

Multifunctionality:

Support synchronous testing of 1-16 tubes of yarn to meet the needs of different production scales.

Customizable circle length specifications, flexible to meet special testing requirements.

Compliant with standards:

Meets domestic and international standards, suitable for testing various types of yarns such as chemical fibers, sewing threads, and reinforcement materials.

Durability and maintainability:

Synchronous belt drive reduces the need for carbon brush replacement and lowers maintenance costs.

Compact structure, small footprint, suitable for laboratory or production line deployment.

3、 Application Fields

Textile enterprises:

Detect yarn line density (count) and control product quality stability.

Optimize production processes and reduce raw material waste.

Quality inspection agencies and laboratories:

Implement national standards for random inspection of yarn quality.

Provide data support for scientific research and develop new fiber materials.

Research institutions:

Study the mechanical properties of yarn, such as breaking strength and elongation.

Develop high value-added textile products (such as functional fibers, composite materials).

International market:

Complies with international standards and meets the testing requirements for exported products.

Used for linear density testing in the chemical fiber industry (such as polyester and nylon).
