Textile Technology - The High Temperature and High Humidity Season Has Been Approaching, How to Solve the Problems of Combing Bonding?

Strengthen air-conditioning management, as much as possible to ensure a reasonable temperature and humidity workshop, reduce the temperature and humidity of the workshop. In summer, the cooling and dehumidification load of air conditioners in the high temperature and high humidity season is relatively large, which brings great difficulty to the air conditioning management. At the same time, the air conditioning operation cost required to adjust the temperature and humidity of the workshop to the ideal state during the high temperature and high humidity season is also high. Therefore, in the high-temperature and high-humidity season, the company generally maintains the temperature and humidity of the workshop in a relatively high position under the premise of ensuring smooth production. Therefore, if the temperature and humidity control is poor in the high-temperature and high-humidity season, frequent or large fluctuations will seriously affect the stability of the workshop life and product quality.

Second, do a good job in the draft area clean

While doing a good job of temperature and humidity control, it is one of the effective measures to reduce the stickiness, entanglement, blocking, and hanging of the draft zone. Brake car refueling should be appropriate to avoid lubricating grease pollution in the drafting area; charter inspection period should see roller, roller, the channel channel cotton wax, oil or sugar adhesion, timely wipe with a warm and wet cloth. The specific practice of cleaning the combing process is as follows:

â—† The combing car carries out warm and hot water cleaning operation method, ie, cleaning with a warm and damp cloth, rubbing the jaws of the jaws on the plate, separating the rollers, drafting rollers, and all the sliver passages and noil passages to clear the adhesion of the triangular airflow plate. The sticky, intarsia, dry with a soft dry cloth and polish with chalk.

â—† When combing the car, the top comb shall be soaked in the warm and hot water container for about 5 minutes. Use a plate brush to clean the viscous material between the top comb needle teeth, clean it and dry it with a compressed air tube.

â—† The equipment maintenance personnel shall clean the responsible machine table with warm and damp cloth every day, rub the nipper lip of the nipper plate, separate the roller, the draft roller, and the sliver passage of all the sliver channel coilers, and then polish it with chalk dust.

â—† The maintenance staff will increase the work of cleaning the top comb with warm water once a week. The combing shifter will increase the work of cleaning the jaws and the top lip and the top needle comb plate in each shift.

Third, ensure that the combing equipment is in good condition

Ensure that the combing process combing equipment is in good operating condition, ensuring the stability of yarn quality and improving production efficiency. Combing and carding equipment should have smooth surface, no damage, no inlays, and the combing area, combing area rack density and total combing point should be optimized to minimize combed cotton mesh breakage, holes, and broken nets. . Specific measures include:

â—† Optimize the array of cylinder rack density. In order to maximize the combing performance of Xilin, it is necessary to rationally dispose and appropriately increase the rack density of the front carding area in the limited combing section of Xilin, and to strengthen the role of rack puncture, grabbing, opening, and carding in the front area. At the same time, it should also avoid too close arrangement of the rack in the front area and cause the comber to break the hole in the cotton net at a high speed.

â—† Reasonable use of brush reverse technology. If used properly, imported brushes can be used for 6-7 years and domestic brushes can be used for 4-5 years. When routinely handling cylinder inliner measures does not work, do not rush to adjust the depth of brush hairs inserted into the cylinder (because doing so tends to exacerbate the damage of the brown hairs of the brush and shorten the service life of the brushes). The brush is backwards to use. This is because most people are using domestic brushes. The brown hair of domestic brushes is relatively poor in elasticity. After a period of time, the brown hair of the brush will fall down along the direction of combing. At this time, the brown hair of the brush is in The forward state with cylinder needles greatly reduces the cleaning performance of cylinders. If the brush is reversed at this time, so that the brown hair of the brush is in a reverse state with the cylinder needle teeth, the brown hair tip can have good elasticity, and the depth of the brush inserted into the cylinder needle teeth can be properly controlled. Linseeds are extremely advantageous in inlays. After using the brush for a period of time, the cleaning brush is equivalent to a 1 mm increase in the depth of the brush inserted into the cylinder. The brush's reverse cycle is usually controlled at 3 months.

â—† Reasonably adjust the brush speed. The speed of the brush directly affects the cleaning of the cylinder and the state of the cylinder-filled fibers. With the rapid increase of the speed of the comber, the technical concept that the ratio of the surface speed of the traditional cylinder and the brush is controlled at 1:5.8-6.8 cannot fully meet the actual needs. Through experiments, the high speed comb brush speed of 1200 rpm was better for Xilin.

Fourth, effectively extend the service life of cylinder rack

Under the premise of ensuring carding quality, the service life of cylinder racks is extended as far as possible to effectively reduce the phenomenon of cylinder hang flowers.

â—† The total number of combing points we use is 41186 points. The first and second sets of cylinder racks have the same specifications, and the racked oblique sheets are all beige. The first group of Xilin rack tooth pieces is easily damaged. When the use time of Xilin reaches eight months or so, the first and second groups of cylinder racks are used interchangeably. This can effectively improve the combing quality and maintain Xilin tooth surface cleaning, extend the service life of cylinder rack.

â—† When replacing the cylinder racks in a unified manner, some of the cylinder racks with relatively good conditions (rack tooth surface damage, no inlays, and no contaminants) can be selected and stored for easy emergency replacement of intarsia. Lin racks to ensure the cleanliness of cylinder surface, reduce machine material consumption and extend the service life of cylinder racks.

â—† By appropriately increasing the density of the cylinder racks in the front and back areas through tests, the Xilin carding three-point gauge (front, middle, and back areas) is strictly controlled, and the cylinder spacing is small to reduce the yarn nep, but An excessively small combing gauge can easily cause fiber damage and damage to cylinder racks. Therefore, the determination of cylinder gauge bar spacing should be based on the cylinder rack density configuration, the volume of small volumes, and customer quality requirements.

â—† The process design of the combing preparation process should give priority to the straightness, parallelism, and degree of separation of the fiber to ensure that the small rolls do not stick during the unwinding process, so as to save cotton, reduce the damage of the cylinder rack, and improve the cylinder rack Service life.

After adopting the above technical measures, the combing process in the high-temperature and high-humidity seasons has greatly eased the phenomenon of sticking, tangling, blocking, and hanging. The combed tin forest basically keeps the tooth surface clean, has no intarsia, and is not damaged. The operator is satisfied with the operation. Degree greatly improved.
