Description
Technical field
The present invention relates to spinning new technical field, specifically a kind of Pure Yarn and its production method.
Background technology
RING SPINNING technology is a kind of current domestic and international application most widely spinning technique, this technology is due to twist triangle zone
Presence and increase the yield of filoplume, while in twist triangle zone because the length of side fiber and center fiber, elongation and
Stress difference, twisting resultant yarn make fiber is radially inside and outside to shift in the process, winding repeatedly, and the yarn strength for being is higher.But with
Various novel spinning modes are compared, and RING SPINNING spinning speed is relatively low, therefore yield is relatively low.
Vortex spinning is a kind of new type of airflow Yarn spinning method, and compared with traditional ring spinning yarn, vortex spinning yarn has
Distinguishing feature.It is that filoplume is few first, since vortex spinning is twisted using cladding, substantially removes the filoplume of 3mm or more；Followed by
Strongly low, also due to vortex spinning is twisted using cladding, the parallel stretch degree of fiber is poor in yarn, the structure and ring spun yarn of resultant yarn
The strength of difference, Air Vortex Spun Yarn is low compared with ring spun yarn, and the bar evenness of resultant yarn is normally close to the level of ring spun yarn, but extremely short segment
Plucked is notable compared with ring spun yarn.Therefore, in order to keep the yarn being spun into flat with certain strength and solid carbon dioxide, it is desirable that the fibre of feeding
Dimension has preferable regularity and length appropriate so that air vortex spinning is relatively suitable for the pure spinning of chemical fibre or blended thick medium size
Yarn is used as raising yarn, or to spun core-spun yarn.
In view of this, the present invention provides a kind of Pure Yarn and its production method, by being joined using inside and outside winding in yarn body core
The fiber assembly of knot uses the yarn assembly body that mutual looping combines so that the Pure Yarn produced has both in the external side of yarn
There are few filoplume and high-tenacity advantage, improves yarn comprehensive quality.
