Tencel/flax vortex spinning elastic core-spun yarn and preparation method thereof
A technology of elastic core-spun yarn and eddy current spinning, which is applied in spinning machine, open-end spinning machine, continuous winding spinning machine, etc., can solve the problem of lower blending ratio of flax fiber and coloring of flax fiber than Tencel fiber. Shallow, poor spinnability and other problems, to achieve the effect of improving spinnability, soft hand feeling and good shape retention

Embodiment 1
[0049] Take the production of 19.7tex tencel / linen vortex spinning elastic core-spun yarn on the MVS861 vortex spinning machine equipped with a filament feeding device as an example. The core-spun yarn is composed of the central T400 composite elastic filament and the outer short fiber. The outsourcing short fiber is composed of tencel and flax in a mass percentage of 7:3, the mass ratio of outsourcing fiber to T400 composite elastic filament is 5:1, and the final product needs to be dyed black.
[0050] The specific production plan is as follows: pretreat the flax fiber to improve its spinnability; pass the flax fiber and tencel fiber through the opening and cleaning process and the carding process to make a mixed raw sliver; The mixed cooked sliver is produced by three drawing processes; the mixed cooked sliver is fed into the air-jet vortex spinning machine, and the T400 filament is fed from the front roller through the wire guide device to make a tencel / flax vortex spinning...
