Do not know do not know the original detergent is so decontamination
Why can detergents decontaminate?
The so-called decontamination, its essence is from the clothing, cloth and other washed objects,
the dirt washed clean. In this washing process, by means of certain chemical substances
(detergents) to reduce the dirt and the surface of the object to be washed and the role of
mechanical agitation, so that dirt and washed objects separated and suspended in the media,
the last dirt Washed away.
From the washing process, the following elements are included:
1, known as the substrate of the washing object;
2, substances removed from the matrix, dirt;
3, the washing liquid used in the washing, that is, in the removal of dirt used in the soap
solution, synthetic detergent solution.
3, the washing liquid used in the washing, that is, in the removal of dirt used in the soap
solution, synthetic detergent solution.
How the stain is removed
The laundry and the detergent are put into the medium together with the detergent in the medium.
The washing liquid dissolves the article, and the dirt is dissolved, so that the combination of
the dirt and the surface of the laundry becomes a combination of dirt and detergent, so that the
dirt is separated The surface of a garment is suspended in the medium. Dispersed, the dirt that is
suspended in the medium is rinsed and removed with water to get clean items, which is the main
process of washing.
It is worth mentioning that the washing process is reversible, scattered and suspended in the
media in the dirt may also be re-deposited from the media in the clothing surface, so that the
object was dirty, this is called dirt re-deposition. Therefore, good performance of the
detergent should have at least two roles: First, reduce the dirt and the substrate surface of
the binding force, with the dirt from the surface of the ability of the object; Second, with
anti-dirt re-deposition.
How does the surfactant work?
Surfactants are the most important ingredients in detergents. Detergents are characterized by
various functions such as moistening, emulsifying, foaming, dispersing, washing, and are related
to the effects of surfactants. It is an organic compound that can significantly reduce the surface
tension of liquids at low concentrations. These compounds have a special molecular structure that
leads to their properties such as emulsification, wetting, foaming and washing.
Surfactants contain two groups, one is a long chain non-polar group, can be dissolved in oil and
insoluble in water, that is, the so-called hydrophobic groups. The other end is a water-soluble
group, that is, hydrophilic. Since the surfactants contain both hydrophilic and hydrophobic
groups, they have good solubility in water or in the oil, thus separating the oil from the laundry.
What are the factors that affect the washing effect?
Washing water
In our daily laundry, pre-wash, main wash, bleach, water, acid and other processes are inseparable
from the water, the detergent is also dissolved in water into a washing liquid, so that the
fabric and dirt moist, swelling, , The role of dispersion, the whole process of washing are
inseparable from the water, showing the important effect of water on the washing effect.
Our daily water is generally from the water plant, all contain a certain amount of inorganic
salts, such as calcium, magnesium, chloride and so on. The size of the water hardness, washing
water quality is the main problem. Long-term use of high hardness of the water, the fabric in
the repeated washing process will be yellowing, hardening, or even damage.
From the perspective of fabric washing, the smaller the hardness of water, the more conducive to
washing.
Mechanical force
The role of mechanical force in the washing is beyond doubt. Solid dirt If there is no mechanical
force, no matter how good the detergent is difficult to remove.
The mechanical action helps the permeate to penetrate, thereby reducing the adhesion between the
surface and the dirt, making the dirt easy to disengage. For viscous dirt, the use of mechanical
force at the same time using friction, is a good way to speed up decontamination. Therefore, in
the fabric washing process, to use some such as rubbing, scrubbing, stirring, carry the investment,
drying and other mechanical force, the cleaning effect will be better.
Washing temperature
Washing temperature is another important factor affecting washing. In general, the higher the
washing temperature, the better the washing effect, but for the enzyme washing powder, most of
the enzyme activity in the vicinity of the highest activity of 40, such as the temperature may
kill the enzyme, the enzyme failure, thereby reducing decontamination ability. Different fabrics,
different detergents and different soils should use different washing temperatures.
