As the summer approaches, the temperature rises, and the products that are cool and comfortable, and the antibacterial health care is “sweetâ€. In some supermarkets and textile home textiles stores in Fuzhou, the reporter found that bamboo fiber products have increased quietly, from cleaning towels, towels, socks, to underwear, home clothes, bedding, etc., many traditional textile items on the tag, " Bamboo" is now available, and the effects derived from it are not enough.
The seller pushes "natural color"
In a bamboo products store in Baolong City Square, the reporter saw that in addition to the common household bamboo products such as bamboo mats and bamboo charcoal bags, the bamboo fiber products occupying the conspicuous position in the store are mostly bamboo products.
From the price point of view, some bamboo fiber sanitary wares and towels that are nominally suitable for sports are more expensive, about 20%-30% higher than similar cotton products. How are they different from everyday household towels? A salesperson in the store claimed that in addition to the smooth and comfortable feel, it is more important that the towel with a lot of bamboo fiber has a good "bacteriostatic effect". It is kept in a damp bathroom for a long time and "will not be mildewed or blackened". He further explained that there are almost no birds in the bamboo forest. Because bamboo contains antibacterial substances and "no pests are supplied", bamboo fibers can naturally "prevent insects and inhibit bacteria."
The reporter noticed several men's socks labeled "Bamboo Fiber" in the supermarket of Lok Fu Bao Long Store, and looked at the specific product composition logo. In addition to showing the proportion of synthetic fibers such as polyester and spandex, bamboo fiber of different brands of socks The specifications are different, and they appear as “bamboo fiberâ€, “bamboo carbon fiber†and “regenerated cellulose fiber†respectively. Among the contents of the attached product descriptions, some claim to have "natural and long-lasting bactericidal effect", some marked "containing chlorophyll copper sodium, have deodorizing effect", and others say "retained bamboo antibacterial, mites, Characteristics of heat and detoxification."
There are many online sales and shopping guides for bamboo fiber products in online shops. Shopkeepers often promote the “natural color†of bamboo fiber in promotion and promotion. A Jiangsu seller emphasized the bamboo fiber bath towel in his online store in the transaction message. “It belongs to natural organic and no added products. It can also be used as a blanket or cover for the baby. Even if it encounters rainy days, it cannot be dried, and there is no need to worry about bacterial residues. ".
On a well-known shopping site's shopping guide commentary, it even claimed that bamboo fiber fabrics can still guarantee their original activity after repeated washing and sun exposure, and have health and beauty effects on human skin.
Buyers should not "as the name suggests "
Is bamboo fiber a natural fiber? Does bamboo fiber really have the magical antibacterial function of "innate"? What is the consumer's cognitive geometry?
In a random interview with reporters, many consumers believe that bamboo fiber should be a natural fiber directly extracted from bamboo in nature. Many people have said that they are advocating green and healthy consumption concepts. If the price is right, they will definitely choose such products.
Experts from the Provincial Quality Supervision Bureau Fiber Inspection Institute said that the understanding of bamboo fiber cannot be “as the name suggestsâ€. In fact, the concept of bamboo fiber covers three major categories: bamboo fiber, bamboo pulp fiber and bamboo charcoal fiber, which have different functions and significant differences in performance. As the current quality evaluation of bamboo fiber products is still in a situation where there is no standard, some manufacturers in the market have taken the opportunity to steal the concept and use partiality to over-exaggerate the effect of rendering new fiber products and misleading consumption.
In the professional testing, it was found that a brand of bamboo fiber towel, labeled product content is "50% bamboo fiber, 50% cotton", the measured results in addition to cotton, polyester, the remaining only "viscose fiber" ingredients; a bed The blanket labeled "100% Bamboo Fiber" has a 100% viscose fiber component.
Dong Haiyan, a tester, told reporters that only bamboo fibrils are directly extracted from bamboo and are natural fibers. However, because the fibers are brittle and easy to break, they are poorly spinnable and difficult to use for spinning or making garments. Generally, it can only be used to make non-woven products, such as environmental protection bags, disposable masks, etc., which have natural antibacterial effects.
Bamboo charcoal fiber is similar to the physical properties of polyester. Usually, nano-scale bamboo charcoal powder is attached to viscose or polyester fiber by special process. Under the microscope of the fiber component detector, the reporter can clearly see the black bamboo charcoal particles. Dong Haiyan said that the granules can achieve good antibacterial and bacteriostatic effects, but other processes can also bring viscose or polyester fibers with such functions.
The bamboo fiber textile products or clothes commonly found in the market are mostly bamboo pulp fibers. Its formation process is similar to viscose fiber, which is a kind of fiber which is processed into bamboo pulp and then wet-spun, and belongs to regenerated cellulose fiber. The statement that such bamboo fiber "can retain the characteristics and activity of natural bamboo" is obviously nonsense.
It can be said that bamboo fiber is not equivalent to "natural fiber". Bamboo pulp fiber and bamboo charcoal fiber with good spinnability are new chemical fibers, which have certain advantages in gas permeability, water absorption, comfort and wear resistance. However, its performance in antibacterial and insect-repellent properties is affected by many factors including fiber content and finishing process, and cannot be generalized. Consumers should rationally look at the effectiveness of propaganda and choose the products they want.
