The  dyeing equipment  employed under high temperatures and high pressure is known as an “ HTHP  dyeing machine.” There are some risks associated with using the HTHP dyeing machine. The safety concerns that must be taken into account when using it are briefly described below. Opening and closing the cover The steam valve must first be closed to stop the heat source once any high-temperature, high-pressure dying is complete. The pressure lowering valve must then be opened, and the lid can only be released when the pressure drop below 0 MPa and temperature drop below 85℃ inside the dyeing machine . Under these circumstances, if the lid still won’t open, it’s best to check the instrument first to make sure it won’t break down and fail to accurately display the residual pressure. To avoid hazard, don’t forcefully open the cover. Additionally, even though the fabric feeding machine is operating normally, if the temperature inside the machine has not yet reached 95 °C, do not close the press

We have discussed the technical characteristics, classification, and development of domestic jigger dyeing machines  before . Here are eight foreign jigger dyeing machines and information on how to choose the right one for you. Foreign jigger dyeing machine 1. OTTO-PRICKEN from Germany ​ OTTO-PRICKEN normal temperature jigger dyeing machine The machine has a straightforward dyeing tank layout. A specially created spreading device minimizes the number of lanes, which cuts down on the amount of time and water used. Additionally, the jigger’s simple and unique tank design gives it a very flexible production capacity, allowing it to meet the needs of both small and large orders on the same machine. The main determining parameters for dyeing are temperature, tension, speed, time, water level, dosage, and liquor ratio (1:2). In order to guarantee the reproducibility of dyeing outcomes, the OTTO-PRICKEN jigger can adjust and monitor these elements in real time. Equipment performance Driving a

According to the dyeing method, dyeing machines can be categorized into three groups: dip dyeing machines, jigger dyeing machines, and pad dyeing machines. Additionally, it can be divided into categories based on whether the dyeing process is continuous or intermittent and if the dyeing machine operates at atmospheric pressure or high pressure. ​ The jigger dyeing machine is the focus of this article among the several forms of dyeing equipment. It primarily introduces classification and development, technical features of domestic and foreign brands, and the best options for jigger dyeing machine. ​Definition, classification and development of jigger dyeing machine Definition and history ​ Jigger dyeing machine was initially constructed out of wood or iron as an open-width dyeing tool. It significantly increased fabric dyeing efficiency over the manual workshop-style operation used at the time and decreased labor intensity and dyeing time. In the late 1970s, the machine  constructed of

The five  objective outside factors  that affect the reproducibility of yarn dyeing have been listed before. The seven additional human-generated subjective elements and solutions are discussed below. Subjective elements of yarn dyeing reproducibility issues 1、Winding quality The apparent color depth of the cheese yarn’s dip-dyed color is greatly influenced by the weight ratio of the dye to the material being dyed. In most cases, package dyeing and loading just counts the quantity of bobbins; additional weighing is not necessary. The weight of the loaded yarn is thus determined by the weight of the winding. Therefore, the winding must weigh 100% of all loose packages. 2、Pretreatment ​ The degree of impurity removal during pretreatment, the level of gross efficiency, the degree of whiteness, the pH after washing, and the hydrogen peroxide depuration following bleaching will all have an impact on the dye uptake rate and shade. 3、Selection of dyes Reactive dyes, vat dyes, direct dyes, etc
