Abstract

The invention discloses a linen drag mark removing method, and relates to the technical field of textile washing. The method includes the following steps of sorting linen, cleaning the drag mark linenin a concentrated mode, flushing stain of the linen with water at the flushing pressure of 5-10 MPa for 5-8 min, soaking the linen in clear water, adding neutral detergent, conducting treatment through ultrasonic waves at the ultrasonic frequency of 15-20 kHz for the treatment time of 10-15 min, prewashing and draining the linen, adding water till the middle water level, adding neutral detergentfor washing, conducting draining, adding water till the high water level, introducing ozone with concentration of 5-10 mg / L, conducting washing for 5-10 min at the water temperature of 55-60 DEG C, conducting draining, and rinsing the linen. The problems that existing linen is prone to damage when drag marks are removed, and the service life of the linen is shortened are solved.

Description

Technical field [0001] The invention relates to the technical field of textile washing, in particular to a method for removing drag marks on linen. Background technique [0002] Linen is textiles such as bed sheets, quilt covers, pillowcases, towels, table cloths, etc. used in service industries such as hotels and hospitals. Due to the complexity of the environment and the population, the linen will be contaminated with various pollutants and breed bacteria. The linen will be used by different people in turn, and it is extremely easy to become a transmission vector of infectious diseases. In order to maintain hygiene and protect people's health, every linen used needs to be replaced in time, and the replaced linen needs to be washed. Linen usually cannot be washed at one time, and the backwashing rate is relatively high. Among them, there are more backwashes caused by secondary pollution. The second pollution of linen is commonly known as drag marks. Most of the drag marks are c...
