Yarn length measuring instrument  

Yarn length measuring instrument

The yarn length measuring instrument is used to shake a certain length of yarn or chemical fiber filament, and use the electronic balance to weigh the weight, and it is used to calculate the linear density of the yarn or chemical fiber filament (tex, tex) Dtex, denier D, yarn count and other indicators). Yarn linear density definition: ①. tex: refers to the weight of a 1000-meter-long yarn in grams at a given moisture regain. ②. Dtex dtex: refers to the weight of 10,000 meters of fiber or yarn in grams at a constant moisture regain. ③. Denier D: refers to the mass grams of a 9000m-long fiber at a given moisture regain. Related standards: GB/T4743 Determination of linear density of textile package yarn skein method, GB/T14343 linear density test method of chemical fiber filament, and other Chinese standards and other national standards. Instrument characteristics: 1. Transmission mechanism: The spring automatic fastening mechanism is adopted to automatically adjust the position…
