Do you know where the starch spots and stains on the gray fabric come from?
When inspecting the gray fabric, there are some gray fabrics at the end or Cloth tail (between 30-35 meters), often found in lumpy pulp spots, there is no regularity, and sometimes large areas of pulp stains are striped and brown, which cannot be repaired in the finished product workshop, and bring immeasurable losses to the subsequent dyeing and finishing processes, so they can only be cut or downgraded. Do you know the reason?
When starting up, the main reason is that the temperature of the cylinder is too low and the resurgence of moisture is too large.
When starting up, (Zucker sizing equipment is very obvious) Sizing tank slow speed (1 speed) and express 2 speed tension , the intermediate value of the grouting force has a large overhang, which occurs during the conversion between the local train and the express train.
1. After the machine is started, the sizing operator and the slurry mixer coordinate to flush the slurry pipe and the slurry return pipe to keep the pipe clean to avoid slurry in the pipe.piece.
2. Before starting the car, the operator cleans the slurry tank, uses some steam, and increases the crawling speed to the end cloth of the warp beam, so that the immersion roller in the slurry, the sizing roller and the pressure drop roller are all clean without dead corners
3. Open the airlock at the edge of the slurry tank to 1/3 position to prevent the slurry from flowing smoothly and easily forming a skin on the edge, and also play a role in heat preservation, and the effect is obviously good.
1. Before driving, ask the operator to set the pre-baking temperature at 100 degrees and the main cylinder temperature at 95 degrees. Only when the predetermined values are reached can the car be driven.
2. Before starting the vehicle, set the tension: the intermediate value of warm yarn tension between slow and fast trains should be shortened as much as possible, for example: drafting speed 1 is 1.0220, speed 2 is 1.009. Avoid excessively large intermediate values.
3. Before the vehicle, the grouting force setting can be increased by 5,000 N on the slow vehicle according to the process requirements, and adjusted to the process range before switching to normal driving. Extended reading: https://www. alltextile.cn/product/product-74-840.html
