Description
Method and device for spinning of yarn with air vortex
Technical field
The invention relates to a method and device for spinning of yarn from staple fibers with air vortex, which finds application in textile industry and especially for obtaining of yarn.
Background Art
Known is a method and device III for spinning of yarn from staple fibers, which are delivered by couple of rollers, go through a special formed transporting chamber, which ends with a feeding needle, is twisted by a rotating vortex and is drafted through an opening of the immobile spindle of the twisting chamber as continuous yarn. The main part of the fiber band receives a twist, and the other one which consists of loose ends of fibers, does not receive twists. By this method the created loose ends of fibers are twisted strongly before entering the central entrance of the immobile spindle. The creating of loose ends of fibers is achieved with the limitation of the distribution of the twists close to the zone of feeding of the fiber band as for the purpose a spiral trajectory of the fiber band is provided.
The disadvantage of the method consists in this, that the spiral trajectory increases the length of the way of the fibers. The twisting air vortex from the tangential grooves in the outlet chamber for twisting, creates strong centrifugal forces on the loose ends of fibers and the fibers which have left with their back end the zone of delivering come out of the yarn as waste.
Another essential disadvantage is the joint movement in the inlet chamber of all fibers collected in a band, which makes difficult the formation of more loose ends of fibers.
Another essential disadvantage is that this device is sensitive to the impurities located in the fiber band. These impurities violate the stability of the air vortex which worsens the quality of the yarn or they obstruct the small central opening of the spindle and cause interruption of the spinning process. The spinning speed is high, and the cleaning takes a lot of time.

The task is solved with method for spinning of yarn with air vortex from fiber band, which is delivered by couple of rollers, goes through a transporting chamber, is twisted by air vortex and is drafted through an opening of the twisting chamber as continuous yarn, as between the line of delivering of the fibers and the receiving opening for the yarn, the main part of the fiber band receives a twist, and the other one which consists of loose ends of fibers, does not receive twists. According to the invention the movement of the feeding fibers on the feeding perforated drafting cylinder is done in the beginning through two zones of congestion of the core fibers and of parallel movement of the wrapping fibers and further joining of the two groups of fibers in one and after that the fibers are fed to the spinning chamber, where they go through different zones of congestion in such a way, that right from the entrance the twisting of the core fibers is controlled, and the loose back ends of fibers are subjected to forces of stretching by the effect of the vacuum of the outlet cylinder, after which they are subjected to forces of drafting and twisting around the formed yarn under the effect of the rotating of the mobile outlet chamber as the air vortex in the twisting chamber is stable. The trajectory and the congestion of the core fibers and of the wrapping fibers are controlled by zones of the vacuum on the feeding perforated drafting cylinder, and after the line of drafting the trajectory and the congestion of the core fibers and of the loose ends of fibers are controlled by the twisting forces applied on the core fibers and the forces of the vacuum of the outlet drafting cylinder and the forces of the vacuum in the spinning chamber applied on the loose ends of fibers. The trajectory and congestion of the core fibers and the forces of drafting and twisting of the loose ends of fibers on the outlet drafting cylinder and in the spinning chamber can change, and the inlet fiber band can be composed of different types of fibers for core fibers and for wrapping fibers as well as the type of twisting in the chamber may be selected according to the type of the yarn.
The device for realization consists of transporting chamber, for forming of loose ends of fibers, placed near drafting couple of rollers and twisting chamber,
connected with tangential grooves for feeding of compressed air, and central opening, for taking out of the finished yarn.

The transporting chamber is composed consecutively of inlet chamber, interstitial chamber and two outlet chambers.
The inlet chamber is moved on distance and at angles from the axis of feeding of the fiber band and is formed at an angle towards the central axis and ends with a flat cross-section placed on distance from the inner surface of the outlet chamber, which is smaller than the radius of the outlet chamber, and in the end of the inlet chamber a guiding cone is mounted.
The interstitial chamber is with central cylindrical opening and tangentially manufactured towards it groove with cross-section equal to the section at the exit of the inlet chamber.
The outlet chamber is composed of two parts, movable one and immovable one, as the movable one has conical entrance equal to the opening of the interstitial chamber and central cylindrical opening smaller than the one of the interstitial chamber, as the opening is slitted by radial slits through the whole frontal part of the bush, which envelops externally both bearings, and has a formed groove for driving belt, and in the immovable part an axis opening is formed, beginning immediately after the movable part and ending near the twisting chamber.
