(57) Abstract:

Usage: textile industry, spinning machine wet spinning bast fibres. Roving spool horizontally placed in the bath liquid, ensuring constant contact with the liquid in the lower part of the roving spools. Descending from roving reel rovings are conducted through the bath and gradually removed from it the excess fluid by pulling Rove through a narrowing in the direction of its motion curved funnel at the exit from the bath. On the convex upper side of the funnel performed a longitudinal slot. Pressed rovings are pulled into the exhaust device and twisted into yarn. 2 S. p. f-crystals, 5 Il.

The invention relates to the textile industry and relates to spinning machines wet spinning bast fibres.

A method of obtaining yarn on a spinning machine, wet spinning and a device for its implementation. The method consists in moistening Rove by placing roving coil in a bath of liquid and holding Rove through the bath to remove excess fluid from the rovings by pulling it through the wringer means at the outlet of the rovings from the bath, pulling Rove and curl praeterit bath of liquid placed on the exit Rove dewatering means, support elements for roving coil, an exhaust device and twisting and coiling mechanism.

The spool of roving is over the bath liquid and the rovings have to make significant way under the action of tension, making it possible stretching with the emergence of false hood. In addition (since), the gathering of the rovings from bobbins is not at the same time, and when the stop operation of the machine is drying Rove and liquid bath she gets to wetting with different humidity.

All this negatively affects the quality of the yarn due to the reduction of its physico-mechanical properties caused by secondary nerovnoi.

The purpose of the invention is improving the quality of yarn.

This goal is achieved by the fact that the roving spool is placed in a bath of liquid horizontally along the bath, ensuring constant contact with the liquid in the lower part of the roving spools, with the removal of excess fluid from Rove carried out gradually with the increase of its intensity in the direction of movement of the rovings from the bath by pulling it through the wringer means along a curved path.

The device is installed in the tub drive is to install roving coil and is made with a slot in the bottom for the passage of the drive roller, this release means is a curved tapering in the direction of movement of the rovings funnel with a longitudinal slot on the convex upper side.

In Fig. 1 shows a General diagram of the device for implementing the method of obtaining on a spinning machine, wet spinning, and Fig.2 - the same, top view; Fig.3 - bearing with the axle; Fig.4 - install the coil on the axis; Fig.5 - wringer unit.

A device for implementing the method comprises a bath of liquid 1 with a fixed inside the supporting elements 2, in the upper part of which is placed shafts 3 to install roving coil 4 and slot 5 in the bottom for the passage of the drive roller 6; set output Rove out of the tub wringer means 7, which is curved tapering in the direction of movement of the rovings funnel with a longitudinal slot on the convex upper side. After squeezing means 7 are located exhaust device 8 and twisting and winding mechanism 9.

A method of obtaining a yarn on a spinning machine, wet spinning and operation of the device is performed as follows. Coil with rovings 4 is placed on axis 3 support elements 2 horizontally along the tub so is the wetting Rove. With this arrangement, the roving bobbins of the latter has a constant humidity. The rovings wound with the coil 4 and is passed through the liquid. A spool carried out due to tension Rove from the supply pair extraction unit 8. The very tension slightly, so as to dramatically shorten the path length of the rovings from the coil to the exhaust device and reduced friction in the bearings of the coil due to the buoyancy force of the liquid in which is immersed coil with rovings. By the gathering of the rovings with the coil 4, it goes around the drive drive roller 6, tight winding rovings. Out of the bath 1 rovings put through the wringer means 7, which is curved tapering in the direction of movement of the rovings funnel with a longitudinal slot on the convex upper side, and carry out the removal of excess moisture from it. Because the funnel has a variable curvilinear cross-section, the removal of excess moisture is gradually increasing to the output of the rovings from the funnel, while the protruding ends of the fibers gradually smoothes and form a single whole with the bulk of the rovings. In addition, when passing through the funnel of the fibers in the roving few tugs and the alignment of their internal stress is primarily on the package by torsion-winding mechanism 9.

The horizontal positioning of the coil with the rovings provides uniform wetting and moisture content in the past regardless of humidity coming Rove on the machine (dry or moist). The presence of longitudinal slits in the funnel ensures that the humidity of the product out of the bath, constant throughout its volume.

A method of producing a yarn and a device for its implementation allow to improve the yarn quality by reducing defects in it.

A METHOD OF OBTAINING A YARN ON A SPINNING MACHINE, WET SPINNING AND A DEVICE FOR ITS IMPLEMENTATION.
