Today, when we advocate healthy and environmentally friendly life, we often hear the name of bamboo fiber. Bamboo fiber can be said to be a very popular kind of fabric at present.
There are many kinds of products made of bamboo fiber, such as bamboo fiber socks, bamboo fiber towels, bamboo fiber bath towels, and even bamboo fiber sanitary napkins. It can be said that bamboo fiber involves all aspects of life. This topic will take you into the bamboo fiber knowledge lecture hall, and teach you the wonderful use of bamboo fiber.
What is bamboo fiber?
Bamboo fiber is a cellulose fiber extracted from naturally grown bamboo. When observed under a 2000-fold electron microscope, the cross section of bamboo fiber is concave and convex, and is full of approximate ellipse.
The round pores are highly hollow and have a strong capillary effect, which can absorb and evaporate water in an instant. It is the fifth largest natural fiber after cotton, hemp, wool and silk. Bamboo fiber has good good air permeability, instant water absorption, strong abrasion resistance and good dyeing properties, with natural antibacterial, antibacterial, mite-removing, deodorant and anti-ultraviolet functions.
Classification of bamboo fiber
Natural bamboo fiber
Natural bamboo fiber is mainly bamboo raw fiber. Bamboo fiber is a natural bamboo fiber made by combining physical and chemical methods.
Chemical bamboo fiber
Chemical bamboo fiber can also be classified as bamboo pulp fiber and bamboo charcoal fiber.
Bamboo pulp fiber: It is a kind of fiber made from bamboo chips and then made into pulp by wet spinning. Its manufacturing process is basically similar to viscose.
Bamboo fiber product bamboo charcoal fiber: It is a fiber product made from nano-sized bamboo charcoal powder, added into viscose spinning solution through special process, and then spun by similar conventional spinning process.
Advantages and disadvantages of bamboo fiber
Advantages of bamboo fiber
1. Soft and warm
Bamboo fiber textiles feel like “silk and satin”. Bamboo fiber textiles have fine unit fineness, smooth handle, good whiteness, bright color, strong toughness and wear resistance, and unique resilience; It has strong longitudinal and transverse strength, and is stable and uniform, with good drapability.
2. Moisture absorption and ventilation
The cross section of bamboo fiber is filled with large and small oval pores, which can instantly absorb and evaporate a large amount of water. The water absorption of bamboo fiber is three times that of cotton. The high hollowness of the natural cross section makes the industry experts call the bamboo fiber “breathing fiber”, and also called it “fiber queen”. The hygroscopicity, moisture resistance and permeability of the bamboo fiber ranks first among the major textile fibers.
3. Warm in winter and cool in summer
Bamboo fiber textiles are used in summer and autumn, making people feel particularly cool and breathable; In spring, it is not only fluffy and comfortable, but also can eliminate the excess heat and moisture in the body. It does not get hot or dry. The function of bamboo fiber textiles is also incomparable with other fibers.
4. Antibacterial and bacteriostatic
Under the microscope, bacteria can multiply in cotton and wood fibers, while bacteria on bamboo fiber products are killed by more than 75% after 24 hours, which are other textile materials
5. Natural beauty
It has the natural beauty effect of bamboo, natural anti-mite, anti-odor, anti-insect negative ion characteristics.
6. UV resistance
The UV penetration rate of bamboo fiber is 6/10000, and that of cotton is 2.5/10000. The UV resistance of bamboo fiber is 417 times that of cotton.
7. Natural health care
Bamboo is full of treasures. It has been closely related to people’s lives for a long time. There are 24 different medicinal effects and prescriptions of bamboo in the Compendium of Materia Medica in China. There are thousands of prescriptions among the people. Bamboo has been making contributions to our human health.
8. Green and environmental protection
In today’s era of advocating energy conservation and environmental protection, the green environmental protection role of bamboo is increasingly prominent. Bamboo can grow 3 feet in height between – night, and can grow and renew rapidly, and can be used sustainably.
To a large extent, it can alleviate the shortage of wood and cotton resources. Bamboo fiber textiles use biodegradable materials, which can be completely degraded by microorganisms and sunlight in the soil. This decomposition process will not cause any environmental pollution.
Disadvantages of bamboo fiber
1. Processing technology
In terms of processing technology, the production process of regenerated bamboo fiber is too long, which also has different degrees of impact on environmental pollution. Environmental protection has become the biggest drawback of developing regenerated bamboo fiber, and the damage of its processing process to the properties of bamboo raw materials can not be ignored. Therefore, the processing technology of regenerated bamboo fiber also needs to be improved.
2. Difficult to obtain
There are two main difficulties in the preparation of natural bamboo fiber: – bamboo single fiber is too short to spin; Second, the lignin content in the fiber is very high, which is difficult to remove. The conventional chemical degumming method has a long process flow, a long cycle, needs to consume a lot of energy, and the equipment is seriously corroded, which causes serious environmental pollution, and the processed quality is not stable enough. Even using biological degumming method is quite difficult, so it needs further research and exploration.
3. Weaving is easy to break
In the process of weaving, bamboo fiber is easy to break due to its characteristics of moisture absorption, wet elongation and large plastic deformation. In garment manufacturing, 100% bamboo fiber has not solved the shrinkage problem well, and the handle and drape need to be improved.
4. Detection and identification
Fiber identification and detection technology is relatively backward, and there is still no effective method to distinguish bamboo fiber and hemp fiber. Therefore, there is no shortage of hemp replacing bamboo in the market.
Bamboo fiber VS pure cotton
Difference between bamboo fiber and pure cotton
Cotton is flocculent and bamboo fiber is filamentous. Because bamboo fiber is regenerated fiber, its length and fineness can be controlled by human beings. The cotton fiber is naturally formed, and its length and fineness are fixed. The cotton has no luster, and the bamboo fiber has a bit of silk brightness, so the fabric made of bamboo fiber feels soft, feels smooth, looks a little velvet, and smells like bamboo.
Which is better, bamboo fiber or pure cotton?
Bamboo fiber: soft and warm, bacteriostatic and antibacterial, hygroscopic and breathable, anti-ultraviolet, deodorant and adsorption functions;
Pure cotton: sweat-absorbing, breathable, moisturizing and warm, soft and anti-sensitive, easy to wash, not easy to pilling, heat resistant, alkali resistant.
How to distinguish the quality of bamboo fiber socks?
Look at the color
The bamboo fiber products with good quality have bright color and high color fastness, and will not easily fade and decolor due to water washing, sun exposure and other factors. Poor bamboo fiber products have dark color or obvious color difference, or are easy to decolor and fade.
Look at shrinkage
The bamboo fiber products with poor quality will shrink greatly after washing, resulting in the appearance deformation and size reduction.
Look at the work
Most of the poor bamboo fiber products are not fine enough, with obvious joints, and there are many phenomena such as jumper breakage.
Poor bamboo fiber products often use chemical additives to improve the appearance quality of products, but it is unavoidable to leave the smell of chemical solution. The high-quality bamboo fiber products have a delicate smell and a slightly fresh taste of bamboo.
Sense of hand
The high content of bamboo fiber in the product will be very fine and smooth depending on the feel, and on the contrary, it will feel very rough and astringent or greasy.
Look at the ashes
There is no black smoke when the silk thread is drawn from good bamboo fiber products and there is no ash after burning. The poor bamboo fiber products have more smoke when burning, and there are black ashes after burning.
Look at ventilation
Spread a piece of bamboo fiber fabric to cover your mouth and breathe, and feel its breathability. The superior ones have even and smooth ventilation.
