Abstract

PURPOSE:To make possible to produce spun yarn of high grade without fiber braking by providing suction and twist tube sucking and twisting sliver with eddy air flow at downstream immediately below front rollers of ring spinning machine. CONSTITUTION:A suction and twist tube S is provided at downstream immediately below front rollers 7 and 8 ring spinning machine. Next, sliver F sent from between a pair of front rollers 7 and 8 is sucked and twisted by said tube to make a shape of yarn. Then, degree of hardness of twist introduced in said process is controlled by traveling and revolving of traveler on ring rail in twisting and winding machine of spindle type.

Description

[Detailed description of the invention] The reality is that ring spinning machines are generally used.

In addition, there is a patent application publication (1974-97425) related to the invention of the present inventor, but contrary to initial expectations, this invention does not completely eliminate the drafted sliver to be sent out from the front roller of the drafting device. There was no drawback to suction Xiaomi. That is, the reason for this is that the opening leak of the inner tube of the vibration absorbing heating tube is open in the shape of a funnel, so the suction force at the head end is weak, and this invention has been forced to be completely abandoned.

For these reasons, in the spinning industry, both inside and outside the world, a
The spinning spinning machine is widely used, but after examining its spinning process in detail, it seems that it is not necessarily satisfactory.

That is, the drafted sliver to be delivered from the front lawn of the drafting device is heated by the rotation of a traveler on a ring concentrically surrounding the spindle, and is wound into thread form while being wound onto a bobbin. The twist rises from the bottom to the top, and in the process of propagation, the twist is approximately 10% due to the frictional resistance of the snail wire supported by the rabbet and the front bottom roller. 111 at the same time as decreasing
During this time, the outer surface of the spun yarn, which is to be shaped into a yarn while being turned, unfortunately becomes very fluffy due to the centrifugal force caused by the turning, and the tensile strength is inevitably reduced accordingly.

What is even more worrying is that the spun yarn changes significantly during this period, which may cause undesirable yarn breakage. That is,
For these reasons as well, the normal rotational speed of the spindle seemed to improve and delamination occurred.

Based on this view, the present invention was made during research to develop a manufacturing device for high-quality spun yarn, and fortunately, significant progress was made.
We have now been able to develop ultra-high quality spun yarn that can be labeled as such, as well as an apparatus for producing it.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following, the present invention will be explained in detail with reference to embodiments shown in the accompanying drawings, but for the sake of convenience, the manufacturing apparatus will first be described with reference to the embodiments shown in the drawings.

In Fig. 1, the drafting device of the D hex/g spinning machine, 7 is its front bottom roller, 8 is the top roller, and the single fibers in the 2Fi troughed sliver F are on the surface of the top row 2. It also shows a case where it happens to resist adhesion and is about to be rolled up.

yx male s u is a vibration absorption heating tube for suctioning the drafted sliver to be sent out from the roller and converting it into a thread form, and is a protruding tube that can be protruded by being connected to seven langes 10 whose head ends are plate-shaped. 1, and an inner tube 5 whose tail outer circumference is formed into a cylinder or an R-headed conical shape 4, and an outer tube 6 surrounding the tail outer circumference 4 of the inner tube with a required gap 5 in between. By combining and feeding compressed air P from the tangential direction into the gap 5, the compressed air is converted into the air temperature fIt,X, while the air vortex flow is
In relation to the inner wall shape 9 to be formed into a conical shape on the outer side 1u, one end e of the drafted sliver F delivered from the front r of the drafting device between 1-27 and 8 [while As a result of narrowly converging this material and turning it into yarn form, it was possible to produce the desired ultra-high quality spun yarn.

That is, this ultra-high quality spun yarn can be used in the vibration absorption heating tube S shown in FIG.
Composition 9! In other words, due to the action of the air vortex X that should spiral while being suppressed by the inner wall surface 9 of the outer tube 6, which is an element, an air vortex flow that has a sharp swirling and squeezing force on the fibers is created. It is spun by the action of
Also, they both have a high degree of elongation.

Therefore, in the spinning process of this ultra-high quality spun yarn, there is almost no yarn breakage of 1.5° + 1, and therefore the spindle 12 always...
Remarkable effects are expected, such as the ability to increase the rotation rate and the efficiency of the next process in which this ultra-high quality spun yarn is used.
