A add elasticity equipment for DTY surface fabric
Technical Field
The invention relates to the technical field of fabric texturing, in particular to texturing equipment for a DTY fabric.
Background
The detail difference between DTY and FDY is that the difference in the drafting speed when the fibers are bundled results in the difference in the process, DTY and FDY are different in a plurality of false twisting processes, i.e. the false twisting is that the fabric is twisted in a certain direction when being processed in the later process, the wound yarn is straight, but in the relaxed state, the fabric is shrunk and fluffed. While FDY is in a relaxed state, it does not contract;
the surface fabric is at the false twist in-process, tensile dynamics is very important, tensile dynamics is little, it is not enough to lead to fluffy dynamics behind the surface fabric false twist, if tensile dynamics is too big, can lead to the surface fabric disconnection, the difference is, summer and winter, the difference in temperature is great, can influence the mechanical properties of wire drawing, if can not in time adjust this dynamics, can make product quality uneven, current device is fixed mostly, can not conveniently adjust in order to deal with the production needs fast, for this reason, we propose one kind and be used for DTY surface fabric add the equipment that plays.
