Hotel textile suppliers tell you washing equipment temperature:
It refers to the temperature of the washing water when hotel linen is washed
Practice has proved that this only applies to the washing of white fabrics, and the hotel bedding washing temperature should be properly controlled when washing dyed fabrics. If the dyed fabric is washed at high temperature, the dye on the fabric is eluted as dirt under the action of the above several aspects, especially some fabrics with poor color fastness dyes, serious decolorization will occur.
Therefore, when washing dyed fabrics, it is necessary to control the appropriate washing temperature according to the different fiber properties, coloring fastness, coloring method and color depth of the fabric, and it is not possible to pursue the high temperature washing effect and decolorize the fabric. In addition, when washing the fabric contaminated by protein dirt, high temperature must not be used, because the protein dirt will rapidly expand the critical surface with the fabric at high temperature, and even penetrate into the interior of the fabric fiber, thus enhancing the bonding fastness of the dirt and the fabric fiber, resulting in the dirt on the fabric carrier can no longer be removed.
Washing temperature has a significant relationship to washing hotel bedding . Increasing washing temperature can have the following effects:
It can improve the solubility of detergent, so as to obtain a higher concentration of washing liquid and enhance the decontamination ability.
It can enhance the solubilization capacity of the washing liquid, thus strengthening the ability to dissolve dirt.
By enhancing the emulsification of the washing liquid, the general dirt can be quickly emulsified and separated from the fabric surface under the washing liquid with high concentration
Due to the increase of washing temperature, the dirt and fabric are heated at the same time, thus speeding up the movement of dirt molecules and fabric molecules, weakening the bonding fastness between the two, and under the action of surfactants with high concentration of washing liquid, dirt is easily separated from the fabric carrier.
In short, from the above aspects, it can be seen that increasing the washing temperature is very beneficial to washing linen. With the increase of washing temperature, the role of the above aspects is more significant, generally can be said that the higher the washing temperature, the better the washing effect. Therefore, increasing the washing temperature is often used as a means to improve the washing quality.
Therefore, when washing fabrics stained with blood, milk, semen, leucorrhea and other protein dirt, they should be soaked in cold water and then washed at low temperature. Increasing the washing temperature can not only promote the dissolution of washing, but also give full play to the decontamination effect of detergents. On the basis of considering the color retention and shape retention of clothing, different washing temperatures should be selected for fabrics with different properties and colors and clothes with different dirt.
