There are many ways to print patterns on fabrics with dyes or pigments.

But the main methods are as follows.

direct

One of the printing methods. Direct printing is a method of directly printing flower-shaped patterns of various colors on fabrics, which is the simplest and most common of several printing methods. In the printing process, the color pastes of various colors do not interfere with each other and do not destroy each other. About 80%-90% of printed fabrics adopt this method. This method can print patterns of white flowers and ground flowers. According to different pattern requirements, it can be divided into three types: white background, full ground and colored background: the printed pattern area on white background is small, and the white background area is large; The printed pattern area on the ground is large, and most of the cloth area is printed with patterns; Direct printing with color background refers to dyeing the background color first and then printing the pattern, commonly known as "overprinting". However, due to the overlapping colors, similar colors or light and deep flowers are generally used, otherwise the colors at the overlapping colors will fade.

avoid

On the dyed fabric, printing paste containing reducing agent or oxidizing agent destroys its background color, partially revealing white background color or color pattern. Fabrics dyed with background color are printed with pulp containing chemicals that can destroy the background color. This chemical is called a discharge agent. Chemical-resistant dyes are also added to the discharge paddle. This discharge printing can get two effects, namely white discharge and color discharge.

Anti-dyeing

Printing process of printing color paste on fabric to prevent background dye from dyeing or developing color, and then dyeing to obtain background cloth. The substance that prevents the printing paste from dyeing is called resist agent. The white pattern printed by printing paste containing resist is called anti-white printing; Dye-proof printing is a printing in which dyes or pigments that are not affected by the resist are added to the dye-proof printing paste to print a color pattern. Resist agent is printed on the fabric first, and then the ground color is pad-dyed. Where the pattern is printed, the ground color can be prevented from dyeing. This method is called resist printing, and three effects can be obtained by this method, namely, resist white, resist color and partially resist dyeing.

Is milk harmful to human body? Nothing is absolute.

It is recognized that drinking milk before going to bed is helpful to sleep. Very effective.

But pay attention to the quantity and limit it, because drinking too much milk is not good for your health.

In addition, milk, like other good foods, is not suitable for people of any physique. The key is how long to drink before going to bed! It is best to drink 45 minutes before going to bed-1 hour. ... so it is more conducive to the sleep of the elderly, so drinking milk at night is conducive to people's rest and sleep. Drinking milk before going to bed is good for human body to supplement calcium ... Milk contains all nutrients necessary for human growth and metabolism, and it is also a completely nutritious food that is most beneficial to human digestion and absorption. Protein, fat and lactose are all contained in milk, and the structure distribution is reasonable. Milk is almost the best nutrition in life, but if it is not drunk properly, it will lead to the loss of nutrients, resulting in unnecessary losses and waste. So, how to drink milk is the best?

First, don't drink milk on an empty stomach.

Experts believe that milk and eggs are the best combination for breakfast, but some people only drink milk and don't eat other foods, which is wrong. Drinking milk on an empty stomach in the morning has many disadvantages. Because it is on an empty stomach, milk can't be fully hydrolyzed, and protein in nutrients will soon be converted into energy consumption, and nutrients can't be well digested and absorbed. Therefore, it is best to eat something before drinking milk, or drink it while eating, which can reduce the lactose concentration and is conducive to the absorption of nutrients.

Second, avoid replacing wine with tea.

Some people like to drink tea while drinking milk, which is more common in southerners than in northerners. In fact, this is an unscientific diet, because milk is rich in calcium ions, and tannic acid in tea will hinder the absorption of calcium ions in gastrointestinal tract and weaken the inherent nutrients of milk itself.

Third, it is not advisable to use 100℃ high-temperature boiling water to make milk, let alone cook it in an electric cup, and the water temperature should be controlled at 40℃-50℃.

Protein in milk will change from sol state to gel state under the action of high temperature, which will lead to the appearance of sediment and reduce its nutritional value.

Fourth, it is not advisable to use bronze for heating.

Copper is not widely used in tableware, but some high-end tableware such as copper hot pot and copper heating cup. Copper will accelerate the destruction of vitamin C, especially in the heating process, copper will catalyze the chemical reaction in milk, which will accelerate the loss of nutrients.

5. Avoid sunlight

Vitamin B and vitamin C in fresh milk will disappear quickly in the sun. Even a weak sunshine for more than 6 hours will reduce vitamin B by half. Therefore, it is best to store milk in colored or opaque containers and in a cool place.

Sixth, don't freeze.

In hot summer, people like to eat popsicles, and some people process frozen milk food by themselves. In fact, eating frozen milk is unscientific. After freezing, the fat in milk is separated from protein, the taste is obviously weakened, and the nutrients are not easily absorbed.

Seven, the best time to drink milk

The calorie supply of breakfast accounts for 25%-30% of the total calorie demand, and it is best to drink a glass of milk with eggs or bread for breakfast; It can also be used as a pre-meal drink around 4 pm; In addition, drinking a glass of milk before going to bed at night is helpful to sleep, and it is best to drink it with a few biscuits.

Drink no more than 500ml of milk every day. Too much milk may lead to diabetes. Drinking a glass of milk before going to bed at night can help you sleep and protect your stomach. I personally like to drink yogurt, which contains lactic acid bacteria, which is helpful for digestion.

Is dyeing hair harmful to human body? Of course it's harmful. The doctor suggested that you should not dye your hair more than twice a year. Even so, it doesn't mean that it will be okay twice a year, just that the consequences are not so serious.

I dyed it once, and a lot of red beans immediately grew on my face, but I couldn't get rid of it. I regret it.

First, oxidant is an important part of hair dye, which is extremely destructive to hair keratin and easy to cause damage to hair. Regular use will make hair dull, fragile, split and easy to fall off.

Secondly, most permanent hair dyes use aniline dye intermediates, and their toxicity and toxicity are higher in cosmetic raw materials. No wonder some people have allergies and even dizziness and nausea when dyeing their hair.

Thirdly, hair dye consists of two components. When in use, it is mixed first and then applied to the hair. I don't know that a chemical reaction took place at the moment of mixing, which produced a high concentration of harmful gas-dioxin. Dioxin is a strong carcinogen recognized by WHO. It enters the body through the respiratory tract and stays in the muscle for a long time, which is difficult to decompose and interferes with human endocrine, estrogen and thyroid hormone. Long-term exposure will lead to genetic variation and deformity of human body and induce diseases such as cancer. Therefore, it is scientific to be pregnant and pregnant women not to dye their hair.

If there is, it is necessary to prevent it. How can we stay away from these hazards to the maximum extent? First, consumers should try to choose a hairdressing salon with good ventilation environment; Second, when buying hair dyeing products, you should buy products from well-known regular manufacturers, and check whether the products have product name, ingredients, instructions for use, production date, expiration date, net content, origin, name, address and telephone number of the production unit. Marked with standardized Chinese characters. Some products with trademarks of Guangming (Beijing), Zhanghua (Zhejiang), Biaomei (Guangzhou), Shuerfa (Shanghai) and Hyundai (Shunde) are all qualified products randomly selected by AQSIQ and recommended for use. Third, the key to deep care after dyeing is baking oil. Shampoo only washes the hair to protect the cleanliness of the head panel; Hair conditioner can provide daily nutrition and moisten hair; Moreover, frequent baking of oil can deeply nourish and care the hair. It's best to do it once a week.

The hazards of hair dyeing mainly include the following aspects:

1. Panel allergic reaction is the most common adverse reaction of hair dyeing. Some people may not have allergic reactions at the beginning of dyeing their hair, but they may have allergic reactions after dyeing for several times. The longer the time, the higher the chance of allergic reaction.

2. Causes changes in hair quality. The dyeing process will affect the moisture imbalance in hair, and a large number of protein will be denatured and reduced. As a result, the hair becomes brittle, the fiber breaks and the natural beauty of softness, tenacity and luster is lost. The more times you dye your hair, the more serious the injury.

3. Causes hair to fall off. Acute and chronic hair dyes can cause inflammatory reactions in scalp and hair follicles, which will cause hair follicles to shrink after a long time, and the hair will become thinner from thick to thin, and finally fall off.

4. Absorbing toxic substances damages liver and kidney function. More common in metal hair dyes and some synthetic organic hair dyes, such as lead acetate and silver nitrate, benzene, naphthalene, phenols and so on.

To prevent the potential harm of hair dyeing, we should pay attention to the following points: 1. Try to reduce the number of hair dyes. 2. Choose a good hair dye. 3. Don't put hair dye on the panel when dyeing hair. In order to prevent it from being coated on the panel, you should first coat the panel with vaseline for protection. 4. Don't dye your hair when the scalp is inflamed and damaged. Damaged panels will increase the absorption of hair dye. For people with special physique, no matter how safe the hair dye is, it may be potentially harmful to him or her, so it is necessary to have a regular physical examination.
