What Is Up Fabric
PU fabric is a type of anti-leather fabric.
PU is a man-made synthetic material with the texture of real leather, very strong and durable, and low in price. The commonly said PU leather is a kind of leather, such as PVC leather, Italian chaff paper, recycled leather, etc.
The characteristics of natural leather and artificial leather
Natural leather characteristics
The characteristics of natural leather are superior to other materials, in that it is flexible, breathable, wear-resistant, fold-resistant, and beautiful...so it is an indispensable material for high-end leather shoes. Its characteristics are:
1. There is a big difference between the advantages and disadvantages of natural leather parts.
Because the skin has different functions on the animal body, its formation and development are also different. After the leather is made, the fiber structure of each part is different, the density is different, the tear resistance, and the tension is different. Especially look, feel extension, flex resistance, and processing performance are different.
2. The fiber (filament) structure of the part has directionality.
Different parts of each piece of leather have different fiber directions.
When the leather is stretched, the elongation is different in different parts.
Some force rates are different, and their elongation rates are also different, and there is a big difference.
3. It is breathable.
This feature allows the wearer's sweat to drain out of the shoe cavity, making the wearer feel comfortable.
4. Good heat and cold resistance.
5. Good abrasion resistance, punching resistance, and easy processing performance.
6. The leather is soft, tough, elastic, and resistant to flexing. Adapt to the physiological needs of the human body.
7. Beautiful, easy to modify, and shape performance.
artificial leather characteristics
Imitation leather that is manufactured artificially and used as an auxiliary or auxiliary material is called artificial leather. According to its structure, it can be divided into synthetic leather and artificial leather.
Features of Synthetic Leather:
1. Good corrosion resistance. Because the surface is coated with plastic, it is not easy to react chemically when it comes in contact with mild acid and alkali. And has anti-moth properties.
2. Good sand and sand prevention performance, contact with sand and sand, can not penetrate the inner layer.
Therefore, when the surface is contaminated, the marina can be controlled wet and its luster will not change
3. The surface is smooth and the material is uniform, and the deep layer of the surface does not have the defects of natural leather. The leather surface is glamorous and beautiful, and the surface color and pattern can be designed artificially. And because the bottom is basically flat and the material is uniform. Therefore, it is easy to mechanize, standardize, and assemble.
4. Poor air permeability. Because the fiber structure of the base is closed by the surface plastic, it has the characteristics of poor air permeability compared with natural leather.
5. It is not resistant to high temperature and high cold, which is determined by the performance of its material.
Features of artificial leather:
The body is light, thin, and soft, suitable for soft upper shoes. The strength is not as good as that of full-finished leather, and it is afraid of scratches. There are more reinforcements in the upper structure to make up for its shortcomings. Artificial leather has poor breathability and sweat absorption.
How to remove ballpoint pen oil from PU fabric clothes
The best answer First, pour alcohol on the scratches of the fountain pen on the clothes. Each scratch should be evenly covered with alcohol. The alcohol should be medical alcohol with a concentration of not less than 75%. Put the side where the alcohol is poured on the clothes up and try not to touch the other sides of the clothes, otherwise, the imprint color of the pen or ballpoint pen may stain other parts of the clothes. Use an ordinary washbasin, prepare most of the basin of water, and then pour two full bottles of bleach into the clean water, paying attention to two full bottles of water. Stir it, and then add a little washing powder. You can control the amount by yourself. Afterward, stir it a little so that the washing powder can fully dissolve in the water. Okay, so now the clothes are completely immersed in water for twenty minutes. Time is up, wash the clothes, there is no mark!
If the mark is a ballpoint pen and the mark is heavy, if there are still traces after using the above method, finally rub it gently with toothpaste and soap, and then rinse with water. (But it is strictly forbidden to use boiling blisters!!!)
There is another way to solve the problem of clothing stained with pen and ballpoint pen marks: don’t rush to put the clothes in the water, but wash the stained parts with gasoline first.
can be removed with carbon tetrachloride solution. But this kind of thing is poisonous and easy to volatilize, and it is very dangerous to burn in an open flame, and it is generally not easy to find. I tried to wipe with alcohol or high-density white wine, detergent is very effective, the above three things are safe, reliable and easy to find as a cleaning agent for ballpoint pen oil stains.
