How to wash hotel linen

Abstract: Hotel sheets are often used in hotels, and their washing is extremely important. The poor washing quality and washing technology of hotel linen not only affect the service quality of the hotel, but also greatly affect the service life of linen. How to wash the hotel linen? What are the common problems in hotel linen washing? Let's have a look. First, how to wash the hotel linen?

1, check the classification

First of all, it should be sorted before washing to achieve targeted washing.

Classification by color: Different linen treatments may cause mutual pollution, and similar linen treatments with different colors are also different.

According to the classification of flax dirt: heavy dirt, moderate dirt and clean dirt. This classification method is aimed at the special dirt of flax in use, and special detergents are generally used to deal with these special dirt. If the heavy dirty linen is treated with the same kind of linen with average dirty degree, it will only cause a lot of waste in backwashing.

Classification according to linen texture: for example, cotton sheets and polyester-cotton sheets must be treated separately, while floor towels should be specially separated and washed and dried by a separate special plane.

2, to stain treatment

Apply some chemicals and use some professional and correct mechanical actions to remove stains that cannot be removed by routine washing and dry cleaning.

3. Water and pre-washing

For the washing of medium and heavy dirt, the water washing step is generally adopted. Pre-washing is a pre-decontamination process by adding appropriate detergent. For particularly serious dirt, pre-washing is a necessary step. Pre-washing can usually be arranged after the washing step or directly into the pre-washing process.

4. Main washing

Under the combination of appropriate concentration, temperature, sufficient action time and other factors, the purpose of decontamination is realized.

Step 5 bleach

This process is a supplementary step of main washing decontamination, which mainly removes pigment dirt that cannot be completely removed in the main washing step.

Step 6 rinse

Rinsing is a diffusion process, using water temperature of 30℃ ~ 50℃ and high water level to remove the residual detergent components containing dirt in the fabric, so as to achieve the purpose of cleaning.

7. Water and dehydration

Using the centrifugal force generated when the washing machine drum rotates at high speed, the water content of clothes in the drum is reduced to the maximum extent.

8, peracid neutralization

The detergent usually used for washing is alkaline. Although washed many times, there is no guarantee that there is no alkaline component. The existence of alkaline substances will have a certain impact on the appearance and feel of clothes, and even worse, it will have an adverse impact on human skin and health. These problems can be solved by acid-base neutralization reaction.

9, soft processing

Soft treatment can make the fabric feel comfortable, prevent static electricity and play a role in lubrication.

10, size

Sizing steps are mainly aimed at cotton products or mixed fiber fabrics, such as tablecloths, napkins and some uniforms in restaurants. After sizing, the fabric surface can be stiff to prevent fuzzing, and at the same time, a sizing film is formed on the fabric surface, which has a certain blocking effect on the penetration of dirt.

Second, the hotel linen washing frequently asked questions

1, the fabric is yellow.

(1) The water did not soften, and rust spots appeared, which made the fabric yellow.

(2) If the drying temperature is too high, the fabric will turn yellow and brittle.

(3) Chlorine bleaching itself will make the fabric yellow, but it will not make it white.

(4) the water is not clear. In the past, the residual chlorine water would make the fabric yellow.

(5) Too many softeners or neutralizers will easily make the fabric yellow.

(6) The quality of the fabric itself.

2, the fabric is gray

(1) The washing water was not neutralized, and calcium soap remained in it.

(2) Detergent quality problem.

(3) Water does not soften, and calcium soap is generated to cover the surface and interior of the fabric.

(4) the performance of the fabric itself.

3. The fabric is damaged

(1) mechanical reasons. The load is too small, resulting in increased tension; Or there are barbs inside the washing equipment; Excessive rotation speed of the washing tub will lead to excessive friction.

(2) The fabrics were not washed separately, and they were put together at sixes and sevens and had excessive friction.

(3) Excessive addition of bleach will seriously corrode the fabric.

(4) Mixing and drying, the drying time is different, which increases the drying time of some fabrics and causes damage.

(5) The quality of the fabric itself.

Three. Matters needing attention in hotel linen washing

1. The laundry equipment used in hotels has different models and performances, so it is necessary to formulate corresponding washing processes and procedures. The main technical parameters of washing process are: washing time, temperature, speed, procedure, reasonable dosage and loading capacity of detergent. The washing procedure is related to water quality, clothes condition, washing chemicals, washing equipment and water level selection.

2. The textile raw materials of washing items are different, such as cotton, polyester cotton and polyester. And different washing processes should be made according to different qualities. For example, the washing temperature of cotton and polyester cotton is different, and the main washing temperature of polyester cotton is

3. The quantity of washing items depends on the capacity of washing equipment. In the washing water containing a certain proportion of chemicals, putting too much or too little washing items will affect the washing effect and the fastness of the items.

4. Pay attention to the selection of high-quality and applicable detergents, and make reasonable dosage according to different washing objects and washing environment. If the washing objects are not distinguished, indiscriminate use of detergents will not only affect the washing effect, but also damage textiles in serious cases.

5. Before washing, the items to be washed should be classified according to the purpose of use, such as tablecloths, sheets, towels, quilt covers, pillowcases, etc. , and then classify according to the color of similar articles. Different colors of a piece of processing may cause mutual pollution, and different colors of similar items are handled in different ways, especially bleaching and colored items can not be mixed. It is also classified according to the degree of dirt, which is generally divided into three categories: heavy dirt, medium dirt and light dirt. The thickness and softness of bath towel, floor towel, hand towel and face towel are different, and the pollution degree is also different. If washed together, it is easy to cause excessive friction. Therefore, these four kinds of towels can be divided into three washing methods: bath towel, floor towel, hand towel and face towel.

6. Chemicals put into the washing water should be fully stirred evenly to prevent local damage to the washing items.

7. Pay attention to observe the lens when spinning at high speed. If winding is found, stop the machine in time and spin it after conditioning. If spinning with a dehydrator requires clean cloth, it will also effectively reduce the damage.

8. After washing, be careful not to use too much force when unloading articles, because in wet state, the strength of the fabric is lower than that in dry state, and it is easy to use too much force.

9. Adopt proper drying procedures and adopt different drying temperatures, drying times and cooling times for different textiles to prevent textiles from shrinking, yellowing, becoming brittle and hardening.

10, regularly check whether there are burrs on the inner wall of washing equipment, and remove them in time if found.
