Washing temperature refers to the temperature of the washing water when washing clothes. The washing temperature has a great relationship with washing clothes. raising the washing temperature can have the following effects:

1. It can improve the solubility of the detergent, thereby obtaining a high concentration of detergent and enhancing the detergent ability.

2. It can enhance the solubilization ability of the washing liquid, thereby enhancing the dissolution ability of the dirt.

3. By enhancing the emulsification of the washing liquid, general dirt can be quickly emulsified and detached from the fabric surface under the rinsing of the high-concentration washing liquid.

4. Due to the increase in the washing temperature, dirt and fabric are heated at the same time, thereby accelerating the movement of dirt molecules and fabric molecules, weakening the bonding fastness between the two. Under the action of the surfactant of the high concentration of the washing liquid, dirt can easily detach from the fabric carrier.

In short, it can be seen from the above aspects that increasing the washing temperature is very beneficial for washing.

As the washing temperature increases, the more significant the effects of the above aspects. Generally speaking, 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.

Practice has proved that this is only suitable for washing white fabrics. When washing dyed fabrics, the washing temperature should be appropriately controlled. If the dyed fabric is washed at high temperature, the dye on the fabric is washed away as dirt under the action of the above aspects. Especially for some dyed fabrics with poor color fastness, severe decolorization will occur. Therefore, when washing dyed fabrics, the appropriate washing temperature should be controlled depending on the fiber properties, color fastness, coloring method and color depth of the fabric. You must never pursue high-temperature washing effects and cause the fabric to decolorize.

In addition, when washing fabrics contaminated by protein dirt, high temperatures must never be used, because when protein dirt encounters high temperatures, the critical surface with the fabric will rapidly expand and even penetrate into the fabric fibers, thereby enhancing the bonding fastness between the dirt and the fabric fibers, resulting in the consequence that the dirt can no longer be removed on the fabric carrier.

Therefore, when washing fabrics stained with protein dirt such as blood, milk, semen, leucorrhea, etc., they should be soaked in cold water and then washed at low temperature. Increasing the washing temperature can not only promote the dissolution of the washing, but also give full play to the detergent's detergent's detergent's detergent's detergent. On the basis of considering the color retention and shape retention of the clothing, different washing temperatures should be used for fabrics of different properties and colors and clothing of different dirt.
