Introduction to dyeing and finishing process

The selection of dyeing and finishing process is mainly based on the variety, specifications and finished product requirements of the fabric, which can be divided into pre-treatment, dyeing, printing and finishing. 

Pretreatment Natural fibers contain impurities. In the textile processing process, various pastes, oils and contaminated dirt are added. The presence of these impurities not only hinders the smooth progress of dyeing and finishing but also affects the wearing performance of the fabric. The purpose of pretreatment is to apply chemical and physical mechanical action to remove impurities on the fabric, make the fabric white and soft, have good penetrating properties, meet the requirements of taking, and provide qualified semi-finished products for dyeing, printing and finishing by the use of dyeing machine.

Cotton: original cloth preparation, singeing, desizing, scouring, bleaching, mercerizing. Polyester: preparation of grey cloth, refining (liquid alkali, etc.), pre-shrinking, predetermined type, alkali reduction (liquid alkali, etc.). Singeing Usually, after entering the printing and dyeing factory from the textile factory, the grey cloth should first be subjected to inspection, tumbling, batching, printing and sewing, and then singeing. the reason: 1 Unburned cloth has too many fluffs and varies in length; 2 poor finish, easy to stain; 3 It is easy to lose hair in the subsequent dyeing and finishing process, resulting in printing and dyeing.

Desizing

During the weaving process, the warp yarns are subjected to large tension and friction and are prone to breakage. In order to reduce the warp and improve the weaving efficiency and the quality of the fabric, the warp yarn needs to be sizing before weaving, which is the adhesion of the fibers in the yarn, and forms a strong film on the surface of the yarn to make the yarn tight and Smooth, thereby increasing the breaking strength and wear resistance of the yarn.

The drive belt of the hydro extractor should be overhauled

The function of the belt in the hydro extractor is to connect the motor and the inner cylinder, and transfer the rotation speed of the motor to the inner cylinder sufficiently, so as to ensure that the inner cylinder rotates at a high speed and achieve the final purpose of spinning. Since the belt is a vulnerable part, I believe that it needs to be regularly overhauled.

Everyone knows that the belt belongs to the rubber component, so after it is used regularly, its tension will have a certain degree of loss, and it will cause its tension force to be biased, affecting the transmission of the normal speed, and eventually causing hydro extractor. The lack of speed is weak and affects the actual mechanical performance. The weight will also cause a series of safety accidents. Therefore, after every period of time, we should check the tension of the belt and make timely adjustments or replacements according to the actual situation.

Moreover, because the belt is mounted on the drive shaft, our drive shaft is a component that is often stained with various types of oil. In this way, after a period of use, the belt will be tainted with a certain amount of oil. With the increase of oil pollution, slippage will occur. In serious cases, there will be problems in that the motor does not turn inside. Therefore, after a period of time, we should check the oily condition of the belt and carry out appropriate replacement adjustment according to the situation.

For the hydro extractor belts, many times are multiple (usually more than 3-4), and some users to save costs, replace only when it is replaced with a serious wear and tear, for this practice I stand The net is unfavorable because the newly replaced belt may be tight and suitable, but the remaining old belt will be too loose. Most of the power may be only responsible for this new belt, causing the new belt to be damaged prematurely. There are some problems that are not worth the trouble, so replacement of the belt should be done as soon as possible.

For the specific replacement method of the hydro extractor belt, we only need to loosen the fastening screw on the right-hand side of the motor first, then push the motor firmly toward the centrifugal hydro extractor, remove the belt by loosening the belt, and then renew the belt. It can be installed in the order of first up and down. Later we can use the wrench to make appropriate adjustments based on the tension of the belt.

Overflow dyeing machine works

The overflow dyeing machine is a dyeing cylinder with a length of about 10 meters. It has a rotating wheel to drive the cloth to rotate. In the lower part of the dyeing machine is a thick and long dyeing tank. The dyeing liquid is present in the dyeing tank and the dyeing of the cloth. The process mainly consists of dyeing in the lower dyeing tank, controlling the time of the infiltration of the cloth in the dyeing tank by controlling the running speed of the cloth, and also controlling the dyeing effect. This dyeing machine is a group of four, each group The dyeing tank is thought of as a connected principle, and the ingredient bar is on the side, which leads to the disadvantage of the dyeing machine, that is, the dyeing result may be that the dyeing effect of the cloth produced by each bar is different. The distance from the dosing tank is far and near, and the four-cylinder exhibits a light to dark effect. For fabrics with darker colors, the impact will not be great, and it is not suitable for lighter colors. The dyeing of cloths tends to have different effects on the degree of staining. Working principle: There is a runner inside to drive the cloth to rotate. The dyeing process of the cloth mainly lies in the dyeing in the lower dyeing tank. By controlling the running speed of the cloth, the time of the infiltration of the cloth in the dyeing tank is controlled, and the dyeing is also controlled. effect. 1,Overflow dyeing machine in the “overflow”: (3) Form: artificially designed overflow pattern. (4) Definition: The phenomenon that the solid surface adsorbate (ion or radical) migrates to the secondary active center is called flooding. (5) Illustration: ACO, NO, and some hydrocarbon molecules may overflow when adsorbed. b: Overflow of water overflows. c: When the column pressure of the drilling fluid is less than the formation pressure, the formation fluid will flow into the well. This flow is called overflow. 2. Advantages: Optimize the design and reasonable configuration of the nozzle, guide pipe and cloth storage tank, so that the fabric is in a relaxed and unfolded state during the dyeing process under different bath ratio conditions, achieving level dyeing. 3. Disadvantages of dyeing machine: The result of dyeing may be that the dyeing effect of the cloth produced by each bar is different, and the distance from the material feeding cylinder is far and near, and the four-cylinder exhibits a color from shallow to deep.
