In order to find the right manufacturer or supplier, it is first necessary to know the respective product exactly. Nowadays "yarn" is used for threads of all kinds. Originally, yarns always consisted of animal "hair", such as sheep's wool. The DIN 60900 standard defines "yarn" as a collective term for linear textile structures. It is therefore a thin, long structure consisting of one or more fibres. This is used for sewing, knitting, roping, weaving or knitting. Retooling the machines is expensive because it takes a lot of time. Digitization has not stopped at this industry either. However, these technical developments make retooling enormously easier.
Different types of yarns:
Yarns are classified according to their structure, the respective spinning process, the field of application, the raw materials and the fibre length. According to the design, there are
In spinning, a distinction is made between dry spun yarns (mechanical spinning processes, dry spinning processes) and wet spun yarns (chemical-technical spinning processes, wet spinning processes).
The yarn types by fiber length include staple fiber yarn (yarn twist). In principle, filament yarn is produced by turbulence. Sewing yarns, knitting yarns, carpet yarns, kitchen yarns, weaving yarns, embroidery yarns, functional yarns are defined by their area of application. A distinction is made between synthetic fibres, hemp, paper, linen, wool and cotton according to the raw materials used. There are also mixed yarns (artificial and natural).
Bulk yarns are a special form. These are produced by texturing and are of synthetic origin. This makes the yarns heat insulating, more voluminous and more elastic.
