Specializing in the production of "tenbro" and "Tianzhu" brand bamboo pulp, bamboo fiber, bamboo yarn, bamboo filament, bamboo wool strips, bamboo fiber...It has more than a dozen intellectual property rights for bamboo fiber products.

Bamboo fiber does not belong to natural fibers, it is made of bamboo pulp as a raw material, belongs to man-made fibers, and viscose fibers belong to recycled fibers, but the raw materials are different.

Bamboo fiber is a kind of cellulose extracted from bamboo, its hygroscopicity, moisture release, air permeability are the first among the major textile fibers, and it can also be antibacterial and antibacterial. And if you use it in the kitchen, your rag won't always be greasy.

There is a trick to identify bamboo fiber towels.

One of the biggest questions is that the ** of bamboo fiber towels is more expensive than ordinary towels, will some merchants take ordinary cotton towels or chemical fiber product towels to pass it off?

Here are a few very useful identification tips: after a period of use, ordinary towels will become hard, while bamboo towels are still soft; After a bamboo fiber towel and an ordinary towel are moistened with water, they are respectively packed in two plastic food bags and placed in an environment of about 30 degrees Celsius for a few days, the bamboo fiber towel is refreshing as new and has no peculiar smell, while the ordinary towel has become moldy, sticky, smelly, and even black; Wet the bamboo fiber towel, then pour the soy sauce and cooking oil on the towel, and then take it to the water pipe to rub and wash, without any detergent, the soy sauce and edible oil are completely rinsed off by the water.

It is said that in order to reduce costs, some merchants weave towels with a mixture of cotton yarn and bamboo fiber yarn in a partial proportion, which is really difficult to distinguish with the naked eye, so when picking, you also have to pay attention to see if there is a mark on the product label that "the composition is 100% bamboo".

Identify the advantages and disadvantages of bamboo fiber products 1, look at the color. Good quality bamboo fiber products have bright appearance and high color fastness, and will not easily fade and decolor due to factors such as washing and sun exposure. Poor bamboo fiber products have dark color or obvious color difference, or are easy to decolor and fade.

2. Look at the shrinkage. Poor quality bamboo fiber products will shrink greatly after washing, resulting in the appearance of deformation and shrinking size.

3. Look at workmanship. Most of the poor bamboo fiber products are not fine enough, the seams are obvious, and there are many jumpers and broken threads.

4. Smell the smell. Poor bamboo fiber products often use chemical additives to increase the appearance quality of the product, but it is inevitable to leave the taste of chemical potions. High-quality bamboo fibre products have a fragrant smell and a slight fresh taste of bamboo.

5. Distinguish the feel. The high content of bamboo fiber in the product will be very delicate and smooth depending on the feel, otherwise it will feel very rough and astringent or greasy.

6. Look at the ashes. Extract the silk thread from a good bamboo fiber product and burn without black smoke, and there is a little white ash after burning. The poor bamboo fiber products have smoke when burning, and leave gray-black ashes after burning.

7. See through. Flatten a piece of bamboo fiber fabric to breathe through your mouth and feel the advantages and disadvantages of its breathability. The high-quality ones are evenly ventilated and smooth.

At present, bamboo fiber is only a kind of viscose fiber, which is made by extracting cellulose and regenerating from bamboo pulp through chemical reaction. Therefore, it is also called bamboo pulp fiber. The special note here is "cellulose", that is, viscose bamboo fiber only uses the cellulose in bamboo.

However, cellulose is not only found in bamboo, all plants contain cellulose, such as trees, Europeans use trees to make viscose fiber, we call wood pulp fiber. The plant with the highest cellulose content is cotton, so China's viscose fibers are made of cotton linters, which we also call cotton pulp fiber. At present, some people still use jute to make viscose fiber, which we call hemp pulp fiber.

Since all kinds of X-pulp fibers use cellulose, and the molecular structure of cellulose in different plants is the same, there is no difference in the essence of any pulp fiber. Therefore, from this point of view, it is difficult to distinguish the difference between bamboo fiber and other viscose fibers.

However, due to the use of modern technology, for example, the fiber is made into a hollow structure, some people advertise that bamboo fiber can breathe, that is, some people say that it is moisture absorption and breathability. In fact, this is not the characteristic of bamboo fiber, if the cotton pulp and hemp pulp fiber are also made into a hollow structure, it will also have the same performance as bamboo fiber.

In fact, using bamboo to make viscose can be made very early, but at that time, because it was believed that bamboo had low cellulose content and its economic value was far inferior to cotton pulp, no one produced it. In modern times, due to the development of advertising, some businesses have used the mouth of experts to promote the function of bamboo fiber, which has greatly improved the market of bamboo fiber, which has led to mass production of bamboo fiber.

Look at the color: the appearance of good quality bamboo fiber is bright in color, and the color fastness is high, and it will not be easily decolored due to factors such as washing and sun exposure, and the poor one is dark in color, or the color difference is obvious, or it is very easy to decolorize.

Smell: The high-quality bamboo fiber smells fragrant and slightly fresh with bamboo, and the poor one will smell like a chemical potion.

Feel: If the bamboo fiber content is high, the feel will be very delicate and smooth, otherwise it will feel rough and astringent, and it will pill.

Look at the ashes: there is no black smoke when the silk thread is smoked and burned, only a little white ash, and the poor silk thread burns with more smoke.

See if it shrinks: Poor quality bamboo fibers will shrink greatly after washing, and the appearance will be deformed and the size will be reduced.

Well, upstairs is right, but it's really difficult to see it, I can only recognize the brand now, the big brand is quite expensive, and there are several brands like Jieliya Bamboo Angel Bamboo Print, I have also used them, they are all good.

Put the cotton and bamboo fiber in the basin at the same time, the sinking of the bamboo fiber is fast, and you can quickly distinguish this point, in addition, the surface of the cotton will be fluffy, and the bamboo fiber is not.

It's really hard to tell, so I can only say that I try to find some reliable brands.
