How to clean sheet sets
The white sheets should be the nightmare of many housewives. The white sheets are not cleanable, and there are no problems before washing. This problem is the macula. If the washed white sheets have yellow spots and are not removed by oxalic acid treatment, the possibility of rust or iron ions may be eliminated. The use of bleaching treatment also failed to remove, and it was ruled out that the pigments may cause macula.
So here is one of the main factors that cause the appearance of yellow spots after washing white fabrics. In some fabrics such as white sheets, white shirts, white underwear, white tablecloths, etc., all contain certain cotton ingredients (not included, but several Not many), some with a large proportion of cotton, such fabrics (except tablecloths) are more or less directly in contact with human skin during use, which will inevitably contain some of the skin's secretions, skin's The secretion is mainly the secretion of sweat glands - sweat, and sweat is 99% water, evaporation residue is 1%, which contains a certain percentage of protein. The content of protein in sweat varies with the body, food structure, season, etc. When these proteins remain in white clothing or sheets, dry or wet state does not show any color, and it can be considered as a kind of “hidden†status". However, when it encounters a certain amount of heat, it is easily solidified and firmly fixed on the substrate, and it is yellowed.
The use of bleaching agents, oxalic acid, etc., is extremely undesirable. This yellowing phenomenon occurs mostly on cotton-containing white or light-colored fabrics. To restore the yellow color to the original fabric color, there is no rescue method. Enzymes have a decomposing effect on proteins, but treatment of proteins that have been cured and "closely" bound to the fabric does not work well. The best way to reduce the occurrence of yellowing in white fabrics is to take effective measures during the washing process. For example, when washing white sheets, the main wash is generally 60-70°C. Do not heat quickly to the preset temperature when heating. , Can be divided into the vote, first in the water temperature of 40 °C plus detergent, a period of time before gradually warming to the preset temperature. If it is a white shirt or underwear can be treated with enzyme detergent, it can be treated with 5% salt water before washing, and then washed with washing solution. On the tablecloths, most of them are food dirt, and they are also rich in protein. You can also refer to the processing method of the sheets during processing.
