I also have a fixing agent for direct dyes!

How to make your own fixing agent:

By weight, the composition and content of each raw material is: 2 3 parts of phenolic resin.

1 part of concentrated sulfuric acid.

1 2 parts glacial acetic acid.

1 2 parts of 25 ammonia.

1 2 parts of ethylene glycol monobutyl ether and 1 2 parts of deionized water. After dissolving the phenolic resin in glacial acetic acid, and then adding concentrated sulfuric acid, the phenolic resin is sulfonated to form sulfonated phenolic resin, and finally the reaction solution is neutralized with 25 ammonia water in the formula ratio, and the fixing agent for dyeing the acid dye is prepared.

Fixing agent is one of the important additives in the printing and dyeing industry, with the development of science and technology, dyeing and finishing technology has also been significantly improved, due to the expansion of international textile ** and people's living standards, environmental awareness of the improvement, textiles are required to be comfortable, clean and safe.

Since the 70s of the 20th century, Germany first launched the "Blue Angel" program, some developed countries in the world.

Japan, the United States, etc.) have successively adopted and implemented relevant laws and regulations, stipulating various indicators of textiles.

Green textiles require that the use of carcinogenic, teratogenic and poor biodegradability and dyeing materials produced by certain aromatic amine intermediates specified in the regulations is prohibited in the printing and dyeing process, and the additives used are also required to contain heavy metal ions and do not produce free formaldehyde, that is, the use of "green additives".

The development and application of formaldehyde-free fixing agent KS is in line with this requirement, and the fixing agent KS is made of organic amines and epichlorohydrin.

A polymerization reaction occurs.

It is used for fixing the color fixing agent KS after dyeing cotton with active, direct and sulfur dyes, and can "bridge" between the dye and the fiber to form a compound, that is, it reacts with the dye molecule at the same time, cross-links with the cellulose fiber, and forms a highly diversified cross-linking system, so that the dye and the fiber are more firmly combined, and the state pin prevents the dye from falling off the fiber and improves the dyefastness.

The active substances in the fixing agent can condense with each other to form a three-dimensional network film on the fiber surface, which seals the dye, increases the smoothness of the cloth surface, and reduces the coefficient of friction.

It is not easy to wear, which further prevents the dye from swelling, dissolving and falling off during the wet friction process, and improves the wet rubbing fastness.

Prepare a bucket of about 15 liters of water at 50-60 degrees, put in 20g-50g of fixing agent, and soak the clothes for 30 minutes. After soaking, do not wash, shake the clothes dry and then dry them, and finally rinse them several times. <

1. Prepare a bucket of about 15 liters, 50-60 degrees of water.

2. Put in 20g of 50g fixing agent and soak the clothes for 30 minutes.

3. Do not wash after soaking, spin off the clothes and then dry them, and finally rinse them several times.

The steps for using clothing dyeing and fixing agents are as follows:

1.Prepare tools and materials: stains, fixatives, water, soup pots, salt or vinegar, etc.

2.Fill the stockpot with water and bring to a simmer. Fill a large soup pot with water until it is 7 minutes full, place it on the stovetop and cook slowly over medium heat.

3.Add fixative. If you use chemical dyes, the fixative should be able to be added directly to the dye bath.

Depending on the material of the garment to be dyed, the fixer to be used is decided. If you're dyeing clothes made from natural fibers, add 250 ml (one cup) of salt while the water is boiling. If you want to dye clothes made of synthetic fibers, add 250ml of vinegar to the water.

4.Add the stain. You can use granular dyes or liquid dyes.

Follow the instructions on the package to determine the correct amount you need to use. If you're using a box of dye powder, you can usually pour a whole packet of powder into slow-boiling water. If you're using liquid dyes, you can usually pour half a bottle.

Stir the dye into the water until evenly distributed.

5.Add fixing agent. In the dye temperature control stage, pay attention to the dye temperature, fixing agent works best between 20 and 45 degrees.

Then, a fixing agent is added to the dye. Generally, the rate of fixing agent used in cold dyeing is that if it is hot dyeing, the rate should be adjusted according to the material of the garment and the formula of the fixing agent, generally between. Next, the dye is stirred for about 10 minutes so that the fixing agent can be well mixed with the dye.

6.Soak your clothes. Soak the garment in the dye and adjust the temperature to 35-45 degrees Celsius for about 10 to 15 minutes.

7.Wash your clothes. Take out the dyed laundry and wash it and hang it up to dry.

The above are the steps for the use of clothes dyeing and fixing agents, I hope it will be helpful to you.

Clothes should be dyed with a dye first, followed by a fixing agent. Now it's especially popular to DIY some tie-dye yourself.

In fact, it is so simple that it can also make your clothes very personal, and you can actively try it.

First of all, soak the items in warm water, squeeze out the water, then prepare a basin, boil the water, pour the dye into the boiling water and stir well, soak the wet clothes into the basin where the dye is poured, and stir well with a hanger. Then pour the fixing agent into a basin of warm water, put the dyed clothes in the water of the fixing agent for 20 minutes, and then rinse it clean and dry, remember not to dry it.

Summary. When using fixing agents, it is important to note that they must be used within 24 hours after adding them.

Hello, dear, I am inquiring about related matters for you, please wait a moment<> dear, the fixing agent used to dye hair has the following <> of use

First of all, use half a bucket of water, about 10L-15L, the water temperature is 50-60 degrees Celsius, put 20g-50g of fixing agent, soak for about 20 minutes, do not wash, blow dry directly.

Then filter it with clean water and you're <>

When using fixing agents, it is important to note that they must be used within 24 hours after adding them.

We hope you find it helpful.

Dyeing dismantling agents and fixing agents are two of the key chemicals used in the dyeing process. Their use is to add color to different fibers and fabric surfaces to get a dye of the desired color. The interactions and chemical reactions between dyes and fibers are important, so the use of dyes and fixatives must be done in a specific step and manner.

First of all, the dye should be added to the dye solution according to the manufacturer's recommended amount, while choosing different dyes according to different dyed fabrics and colors. During the dyeing process, constant stirring and circulation should be carried out so that the dye is evenly distributed throughout the liquid. After staining, a wash should be performed to remove excess dyes and other chemicals, which can help maintain the durability and stability of the staining.

After that, the fixing agent should be applied to the dyed fibers and fabrics. This can be done by soaking, spraying, or other means. Fixing agents work by locking the color on the surface of the fibers and fabrics, preventing fading and fading.

The dosage of fixing agent should also be determined according to the manufacturer's recommendations, as well as the combination of dye and raw material.

When using dyes and fixing agents, factors such as temperature, time, and stirring must be followed to ensure the success of the process and the accuracy of the desired color. Also, be mindful of personal protective measures, such as wearing gloves and masks, to avoid poor contact with chemicals***. Finally, dyes can fade and fade over time, even with the right dyeing and fixing steps, so it's important to maintain and maintain dyed garments and textiles.

In conclusion, the use of dyes and fixing agents requires care and the correct procedures and techniques to ensure the accuracy and stability of the desired color. The success of this process depends mainly on the selection and application of the stain, the method of fixation and the maintenance. <>
