The method of repairing the broken end of yarn-dyed weaving shaft

The method of repairing the broken end of yarn-dyed weaving shaft

1. Filling the head with slurry on the cylinder foot

Prepare the slurry, dry the slurry on the yarn-dyed tube foot and make it into patch yarn, which is used in the weaving workshop to perform patching operation according to the process. Its scope of application is to mend the broken end of the weaving shaft of the non-double weaving shaft variety of the cylinder dyeing variety.

The specific operation is as follows:

(1) Preparation of the tube foot. Pour the yarn-dyed bobbin at the winding machine according to the provision of the yarn-dyed darning yarn into a qualified bobbin (must use a plastic pagoda tube), and complete the preparatory work of the bobbin.

(2) Preparation of slurry. After sizing, the slurry in the slurry pot is mixed with an appropriate amount of water and boiled to complete the preparation of the slurry.

(3) Put the dilute slurry in the slurry pot into the barrel prepared in advance for sizing the yarn-dyed tube feet.
(4) Slurry operation. After dipping the yarn-dyed tube feet one by one into the dilute slurry in the barrel, hold the yarn-dyed tube feet repeatedly with both hands, so that the slurry can penetrate into the inner layer of the package yarn, and ensure that the inner and outer layers of the package yarn are evenly sized.

(5) drying. The dyed yarn-dyed tubes that have been coated with slurry are put into the drying room of the sizing machine one by one for drying, and the yarn-dyed tubes after drying are the patch yarns.

During the weaving process, if a certain color is found to be broken, the yarn of the corresponding color should be selected from the equipped yarns in time, and it can be repaired to the position of the broken end through the yarn guide hook at the beam of the loom. Can guarantee normal weaving. This kind of yarn-dyed mending yarn is sticky and serious, with high yarn breakage rate and defective cloth rate, low mending utilization rate, and too much yarn waste. Therefore, since the company introduced the single-yarn sizing prototype, it switched to the “single-yarn sizing prototype sizing method”.

2. Small prototype of single yarn sizing machine sizing repair head

The yarn-dyed bobbin is made into patch yarn by sizing the single yarn sizing prototype machine, and the weaving workshop performs patching operation according to the process when necessary. This method is suitable for repairing the broken end of the weaving shaft of the non-double weaving shaft variety of the cylinder dyeing variety.

The specific operation is as follows:

(1) Preparation of the tube foot. Send the remaining bobbins after the warping process is finished to the warp beams, and send them to the single yarn sizing prototype according to the configuration requirements of the mending yarns, and complete the preparatory work of the bobbins.

(2) Preparation of slurry. Use the same number of sizing agent as the single yarn sizing sample machine.

(3) Sizing and drying operations. After the start-up process parameters are set on the single yarn sizing prototype machine, sizing and drying are carried out according to the equipment requirements of the mending yarn, and the yarn-dyed bobbin after sizing is the mending yarn.
