Clothes detergent is a household product used to clean clothes and is essential in daily life. The clothes cleaning care market has three parts: clothes detergent, softener, and laundry auxiliaries.
And clothes detergent accounts for the major part of the clothes care market. In the laundry cleaning process, clothing detergent is the main role of the product, whereas laundry aids are used to match and enhance the detergent effect.
Fabric softener is a product used to restore the smoothness, elongation, and elasticity of fibers on the surface of clothes after the laundry process and to save ironing time.
The main components of detergents are surfactants, which are organic compounds with two parts of molecular structure: hydrophilic and lipophilic groups.
Surfactants are generally divided into two categories, ionic surfactants, and nonionic surfactants, based on whether they can be decomposed into ions in aqueous solutions. Ionic surfactants can be further divided into cationic surfactants, anionic surfactants, and amphoteric surfactants.
It has been proved that only anionic surfactants and nonionic surfactants can play a positive and effective role in fabric decontamination in fabric washing. Therefore, these two surfactants become the main material of the laundry detergent.
Detergents should have good wettability, permeability, emulsification, dispersion, solubilization, and foaming and defoaming properties of these properties is a combination of detergent washing performance.
There are many kinds of detergent products, which can be basically divided into several categories: soap, synthetic laundry detergent, liquid detergent, solid detergent, and paste detergent.
How to choose detergent?
Cellulose is more stable under alkaline conditions but can be hydrolyzed under acidic conditions, so you should choose a weak synthetic detergent or soap for washing cotton clothes and accessories.
The main component of wool and silk is protein, and protein can be hydrolyzed under acidic or alkaline conditions, so washing wool and silk clothes, it is best to use a neutral synthetic detergent.
Some clothes will shrink after using detergent, why is that?
Sometimes there is a change in the size of a garment after it has been soaked in water or washed and dried, called shrinkage. This is because the clothing fiber fully absorbed water, water molecules into the fiber inside the fiber volume expansion, due to the increase in fiber diameter, while the length of the increase in less, so the fiber woven into the yarn thicker, the degree of bending in the clothing increased, forcing the clothing shrinkage.
In addition, in the textile process, the fiber yarn has been stretched many times, and soaking or washing fiber yarn to gradually restore the original shape, is also the reason for the shrinkage of clothing.
Cotton, hemp, silk, wool, and viscose fibers woven into the clothing shrinkage rate large, while synthetic fibers woven into the clothing shrinkage rate small.
