No matter how the fabric is treated, it will not fade. Some clothes are particularly easy to discolor in daily life. The decoloured clothes are not as beautiful as before, and it is easy to dye other clothes. Let's see how to deal with the fabric without fading.
How to deal with the colorfast 1 fabric is as follows:
1, pickling method
Add some common vinegar to the washing water and soak it for a while, then you can add the dye. Pay attention to the amount of vinegar, or it will be easy to dye light-colored clothes.
2, flower dew water method
First, wash clothes in the usual way. After the clothes are rinsed, drop a few drops of toilet water and dye them into clear water, then soak the washed clothes in this water for ten minutes. The clothes washed in this way can also play the role of disinfection and sterilization and remove the smell of sweat. This method is more suitable for cotton fabric and wool fabric.
To deal with the seriously faded cloth, you can soak the clothes in salt water for about 30 minutes, then wash them with clear water, and then wash them with general washing methods. This can prevent clothes from fading, especially black or red clothes, and the effect is more obvious. Sweaters fade easily when washed. Soak the sweater in herbal tea water for 10 minute, and then wash it by general washing method. After washing in this way, the sweater can not only be washed cleanly, but also will not fade, and it can also prolong its service life.
How to keep clothes from fading;
Method 1: We can add a little salt to the water when washing clothes. Washing clothes with light salt water can keep our clothes longer in color, and adding alum can make our clothes more colorful.
Method 2: add vinegar. Adding proper amount of vinegar to the water in which we soak clothes can also make the color of clothes less prone to fade. Remember to add white vinegar, not old vinegar.
Method 3: We can turn the clothes upside down when hanging them, and don't let the colored side face the sun directly. My grandmother gave it to me. Although I don't know why, the personal test is effective.
How to handle the fabric without fading? Cellulose fibers such as cotton are usually dyed with anionic water-soluble dyes such as direct dyes and acid dyes. These dyes have complete chromatograms and bright colors. However, because this kind of dye contains water-soluble groups in its structure, the dye is hydrophilic, and the color of clothes is easy to fade and fade when washing. The fading process will make the appearance of clothes obsolete; At the same time, the dye will be stained on cotton clothes after being hydrolyzed into dye solution, resulting in staining and color matching.
Solid love
Speaking of which, I'll give you a concept, color fixing. As the name implies, color fixation is to improve the color fastness of fabrics; Additives that can improve color fastness are called fixing agents. Next, I will systematically explain how to solve the problem of cotton-padded jacket's fading and staining from the source.
Mechanism of fixing agent;
First of all, the dyeing mechanism and fastness of dyes on different fibers are different, so the fixing mechanism and application of fixing agents are also different.
(1). Cationic groups such as quaternary ammonium salt or tertiary amine salt in the fixing agent molecules are combined with anionic groups in the ionic dye structure through ionic bonds, so that the dye and the fixing agent form insoluble color blocks and deposit on the fiber, thus improving the color fastness of the dye on the fabric.
(2) The reactive groups in the fixing agent molecules cross-link with the reactive groups in the dye molecules and the hydroxyl groups in the cellulose molecules, which reduces the water solubility of the dye.
(3) Using the film-forming performance of the fixing agent on the fabric to improve its dyeing fastness. During the high-temperature drying process of the fabric treated by the fixing agent, the reactive crosslinking groups on the fixing agent molecules cross-link themselves into macromolecules, forming a protective film with certain strength on the surface of the fabric and fiber, and coating the dye on the fiber, so that the dye is not easy to fall off.
Types of fixing agents
According to the principle of fixing agent, we can divide fixing agent into two categories: reactive fixing agent and non-reactive fixing agent.
Reactive fixing agent refers to the introduction of reactive groups, usually epoxy groups, into the fixing agent molecules, which can form valence bonds with some groups in the fiber dye molecules, which is more conducive to the improvement of dyeing fastness.
Non-reactive fixing agent refers to two water-soluble groups: film-forming and blocking on the fiber surface, and its main types are cationic fixing agent and resin fixing agent.
Daily washing protection law
1, the use of nursing laundry detergent: laundry detergent is easier to rinse, not easy to fade, does not hurt hands, and prevents static electricity; Laundry liquid generally contains softener, so it is softer, more comfortable and brighter than washing powder.
2. Anti-drying method: reverse drying clothes can prevent most fabrics from fading due to direct ultraviolet radiation, especially some dark clothes. Try to dry brightly colored clothes in a dark and ventilated place.
3. Black, red, blue and other clothes that are easy to fade are best soaked and washed separately.
For pure cotton clothes, what we can do is to pay attention to daily washing protection. Pure cotton clothes are not easy to fade, so it is best to choose clothes with medium and high price. The fabrics of medium and high-priced clothes will basically have solid colors, and the colors of clothes will be more durable, brighter and more comfortable to wear.
How to deal with fabric colorfastness 3 anti-fading tips
The first trick: salt water immersion method
This method is most suitable for dealing with the fading problem of jeans and fancy clothes, and the effect is excellent. In order to prevent the newly bought clothes from fading, soak them in concentrated salt water for half an hour before going into the water for the first time, and then wash them in the usual way. If the color still fades slightly, you can soak it in light salt water for ten minutes before each cleaning. If you persist in this way, the color of the clothes will never fade!
The second measure: pickling method
This method is mainly aimed at cotton-padded jacket and knitwear with bright colors such as red or purple. The method is to soak these clothes in some ordinary vinegar for a period of time before washing them! But the amount of vinegar should not be too much, otherwise it is easy to dye light-colored clothes. If you can wash clothes like this often, you can ensure that the colors of clothes are as bright as new!
The third measure: toilet water cleaning method
This method is more suitable for cotton fabric and wool fabric. The method is to wash clothes according to the conventional method. After the clothes are rinsed, drop a few drops of toilet water into clear water, and then soak the washed clothes in this water for ten minutes. The clothes washed in this way can also play the role of disinfection and sterilization and remove the smell of sweat.
The fourth measure: anti-dry method
This method is most commonly used, especially for some dark clothes. The method is simple, that is, hang the clothes upside down.
Special reminder: most fabrics can't be directly irradiated by the sun, because ultraviolet rays are the chief culprit of clothes fading. So we should not only hang clothes backwards, but also hang clothes in a dark and ventilated place if possible.
How to renovate faded clothes?
Some stains will make the original color of clothes disappear. In addition, there are some ways to remove stains. If the fading test is not done first, the original color of clothes will disappear or fade.
1, put on plastic gloves and a mask, mix ammonia with water 1: 1, dip a cloth in the mixed solution and pat it on the stain, then rinse it with water. However, this method is not suitable for wool and silk.
2. If the fabric fades due to the use of ammonia water, immediately soak the clothes in water to remove the residual ammonia water, and then put white vinegar on the clothes and soak them in water 1 time. Apply white vinegar before soaking, because white vinegar has the function of fixing color. If you want to restore the fading of the carpet caused by urine and other stains, you can first dilute 1 tablespoon of ammonia with 1 glass of water, then dip a sponge in water and apply it to the stain, and then wash it with clear water.
Note: Wear gloves when using ammonia water. Do not mix ammonia water with bleach or any other cleaning products, otherwise it may produce toxic gas.
