Embodiment 1

[0019] The invention relates to a method for treating broken yarn in the spinning process of ring spun spun yarn, which uses the method of ring spun spun yarn to deal with the broken end in the spinning process. Yarn, thread the yarn through or hang into the traveler 6, wind the end of the yarn close to the traveler 6 around the bobbin 5 or bobbin 8 according to the spinning direction, and pass the other end of the yarn upward quickly or Wrap into yarn guide hook 4, connect with the whiskers 3 that send out between front roller 2 and top roller 1, continue spinning.

[0020] Winding one end of the leading yarn on the bobbin 5 or bobbin 8 is the same as winding the raw yarn on the empty bobbin on the spindle when the ring spinning spun yarn is spinning. When starting to spin a new doffing after doffing, the spindles that have not been left need to be spun by the car operator. When the car spun, the yarn is usually hung into the traveler and one end is placed on the bobbin 5 or ...

Embodiment 3

[0027] The difference between this embodiment and Embodiment 2 is that when it is used for the yarn breakage treatment of the compact spinning ring spinning frame, if the end of the yarn drawing close to the yarn guide hook is connected to the beard, if the "wrapping roller" method is still adopted For hooking, it is necessary to wind the roller closest to the yarn guide hook and the matching top roller. Due to the compact spinning device, in this case, the yarn needs to be fed between the grid ring and the matching top roller.

Embodiment 4

[0029] The difference between this embodiment and embodiment 2 is:

[0030] The automatic device is used to complete the processing after the broken yarn of the ring spinning spun yarn. In order to facilitate the design of the automatic device, the processing sequence after the broken end of the ring spun spun yarn is as follows: after the spun yarn is broken, first pull out a section of the yarn, and after the traveler 6 is found, the yarn will be drawn. 9 passes through or hangs into the traveler 6, and then winds the leading yarn 9 into or passes through the yarn guide hook 4. These two steps do not have strict requirements on the required time, and then wind the end of the leading yarn 9 close to the traveler to the On bobbin 8 or bobbin 5 (the process time is not very certain, but it can be detected whether the threaded yarn is wound on bobbin or bobbin), once the end of threading thread 9 close to the traveler is wound to bobbin 8 or bobbin 5, then in a short period of t...

Abstract

The invention relates to a processing technology of jointing ring spun yarn after breaking, in particular to a method for processing broken yarn in a ring spun yarn spinning process. The broken yarn processing method adopts guide yarn to guide and wind fiber strands sent out by a drafting system roller to a bobbin or cop after passing through a yarn guide hook and a steel wire ring, one end of the guide yarn is wound on the bobbin or cop, and is not connected to original spun yarn on a ring bobbin, and the other end is of the guide yarn is connected with the fiber strands sent by from the drafting system. Compared with an existing ring spun yarn jointing technology, the method for processing the broken yarn in the ring spun yarn spinning process has the advantages that operation complexity is reduced, the steps of spindle braking, bobbin pulling, end finding, bobbin inserting and the like are not needed, and automatic treatment after the ring spun yarn breaks is favorably realized.

Description

technical field [0001] The present invention relates to the treatment technology of ring spun spun yarn breakage, in particular to a treatment method for yarn breakage in the spinning process of ring spun spun yarn. After being guided by the yarn guide hook and the traveler, it is wound onto the bobbin or bobbin. One end of the leading yarn is wound on the bobbin or bobbin, and is not connected with the original spun yarn on the spun bobbin. The other end of the leading yarn is connected to the pulling The strands sent out by the stretching mechanism are connected. Compared with the existing ring spun spun yarn piecing technology, the method for processing interrupted yarns in the ring spun spun yarn spinning process of the present invention reduces the complexity of the operation and does not require brakes. Spindle, extubation, head finding, intubation and other steps are beneficial to realize automatic processing after ring spinning yarn breakage. Background technique ...
