‌1Introduction‌

The yarn length measuring machine is also known as a hundred meter winding machine, because in practical use, it is usually shaken 100 The yarn is meters long, which is why it has such a figurative name. It is mainly used to shake the sample yarn on the yarn tube with a yarn frame to obtain yarn strands, in order to determine the linear density (or count) of the yarn and test the strength of the yarn strands.

IIworking principle

After setting the number of test cycles, wrap the end of the sample around the yarn frame through the yarn guide, tensioner, and transverse yarn discharge device. Start the instrument, rotate the yarn frame, and count. When the rotation reaches the set number of cycles, it will automatically stop. By driving the yarn frame to rotate with a motor, the yarn is wound into a set number of turns. After the winding is completed, the yarn mass is measured and the line density is calculated based on the number of turns and the length of the turns.

Operation method:

Place the yarn sample under standard temperature and humidity conditions (such as20±2°C，65±4%RH）Perform humidity balance at least24Set the number of yarn loops, adjust and set the pre tensioner according to the standard or yarn type, clean the yarn frame to ensure there are no burrs, lead out the yarn from the roll, pass it through the yarn guide hook and tension device, and fix the yarn head on the clip of the yarn frame. Start the instrument, the yarn frame begins to rotate at a constant speed, and the yarn guide device moves laterally to evenly arrange the yarn on the yarn frame. After reaching the set number of turns, the instrument automatically stops. Be careful to remove the yarn and tie a knot to prevent it from unraveling. Ensure that the joint is secure and does not affect the length. Weighing: The accuracy of use should be at least0.001gThe electronic balance is used to measure the net weight of the yarn and calculate it using a formula. Typically, multiple yarns need to be tested (such as...)10Take the average as the final result and calculate the coefficient of variationCV%.
