Laundry linen washing operation matters of major
1. Linen in the washing process, must be the correct use of cleaning material. Hard water areas, in particular, must be added in the process of the main wash water softener.
2. The draperies, pillowcase, such as light dirt cloth grass, when choosing bleach in the washing process, should choose color bleaching powder instead of chlorine bleaching powder. As chlorine bleaching powder is a strong oxidizer, it can make the impurities in the water of the chemical reaction to produce a metal chloride, residues in linen fiber, through the ironing or drying and in the air oxidation, make the yellow cloth grass.
3. In the washing process, water is also very important. Linen in the washing, the dirt is washed down, in aqueous solution to form the mixture of detergent and dirt. It is the mixture of temperature at this moment. In the process of water, if add cold water directly, it will cause grass cloth contraction, the mixture of dirt firmly locked inside the fiber. In the long term linen will appear dirt deposition.
4. When washing towel class, not a good master of washing procedure, it is easy to make the towel yellow, grey, hard and so in strict accordance with the specification of washing process is very important, especially the towel class, many hotels, hotels and social laundry factory will face similar problems.
class linen washing towel:
in the first place in the main wash must add water softener, bleach it is best to use bleach, as far as possible when water in the hot water for washing. The post-processing, must add neutralize acid powder. Add soft powder to be right amount, and quantity too much yellow makes the towel. Dehydration is not completely towels will be grey. For a long time without neutralizer towel can harden. To make the cloth grass to wash well, every washing procedure strictly, otherwise, as long as there is a link error, can affect the overall effect of washing.
by long washing, concluded a little experience, washing towel joint line of the reference:
in the towel washing seven days a week, four days to white towel with oxygen bleaching powder, after three days to white towel with chlorine bleaching powder ( Because all the towel flow washing at least three days) , both oxygen bleaching powder and chlorine bleaching powder, when joining machine, when the temperature reaches 55 ℃ - 60 ℃, will dilute good bleach in roller forward to join and immediately rushed, in order to avoid heavy bleaching powder of the cause damage to the cloth grass. Put into use for the new towel fabric washing when had better choose oxygen bleaching powder for whitening.
the above way of bleached both reduces the damage to the towel fabric of bleach, and ensures the towel on the pigment stain removal, effectively prevent the towel fabric grey and dark.
wash white linen
most of the hotel, the hotel housekeeping department use the cloth of grass is given priority to with white, therefore attaches great importance to dialogue. If only use bleach, can only get a whiteness. But look carefully, you will find that there is light yellow or brown, this is mainly fabric itself has the trace of natural light blue light absorption. So to make the white fabric to achieve an ideal state, can be quantitatively for linen whitening on a regular basis.
there are two ways on whitening white fabric: garland whitening, fluorescent whitening.
1. Garland whitening - - Why is by adding a certain amount of blue show should be white instead?
different wavelength of light waves, can let a person feel sense of different color. Color normal person can see after the natural white light through a prism, will disperse into a multicolor spectral band. In the dyeing and finishing, to learn, there is a complementary color, and the yellow and blue are complementary colors. When these two kinds of color mixing, can give a person the sense with white, because white fabric with a yellow and brown, add a certain amount of blue, tone up the yellow on the white fabric, make it appear white. Use the principle of complementary color, use some blue or purple of the disperse dye, make its uniform adsorption on the white fabric in order to remove the fabric on the yellow or brown, this is the principle of garland whitening.
garland processing, should choose different according to different fabric dyes, in order to achieve the best effect.
a. Direct fast LAN: can be used for cellulose fiber fabric, generally recommended dosage of 0. 006 g - 0. 003 grams/liter, five minutes.
b. Disperse dyes: can be used for polyester/cotton blended, dosage is 0. 5 g/l, five minutes temperature 40 ℃. Before undergoing whitening, should first will dye water dissolved in full, and then in water use. After this kind of treatment of white fabric appearance ( Whiteness) Relatively beautiful.
2. Fluorescent whitening agent whitening
it will not be visible ultraviolet light into visible light blue or purple, increase the reflectivity fabric, give a person a kind of clean and pure feeling, fluorescent whitening agent is a kind of coating, and fiber has the affinity, therefore, adsorption on the fabric fastness and whitening effect is good.
the commonly used fluorescent whitening agent VBL: used for cellulose fiber, light yellow powder, but is not suitable for use in conjunction with anionic surfactant.
