Q:Carbon nanotubes and carbon nanofibers are the same thing? What's the connection?

Carbon nanotubes and carbon nanofibers are not the same thing, and they all belong to nanoscale carbon materials.

Q:What is the difference between regenerated fibers and Lesel fibers?

The development of regenerated cellulose fiber can be divided into three stages on the whole, forming the three generation products. The first generation was the ordinary viscose fiber, which was released in the early twentieth Century to solve the cotton shortage. The second generation was started in 1950s to realize industrialized production of high wet modulus viscose fiber, its main products include Japan R & D toramomen (named Polynosic) and the change of American R & D high wet modulus fiber HWM and Lenzing Co in late 80s by the new process of production of Modal fiber. In late 60s, due to the rapid development of synthetic fiber production technology, low cost and adequate sources of raw materials, synthetic fibers have greatly affected the market position of regenerated cellulose fiber. Many research institutions and enterprises to pay more attention to the development and application of new synthetic fiber. During this period, the development of regenerated cellulose fibers in the world tended to be stagnant. Third generation products are introduced in 1990s staple fiber Tencel (Tencel), filament Newcell as a representative. Influenced by the awareness of health and environmental protection, nature and other factors, people have a new understanding of the physicochemical properties of regenerated cellulose fiber, a new generation of regenerated cellulose fibers has been fully improved, therefore, the application of regenerated cellulose fibers of the re emergence of rapid development.

Q:70% cotton 27% polyester fiber 3% spandex what fabric is it?

Knitted fabric: This is not set down, the first organization has not set down, there may be a single jersey, there may be other types of knitted fabric; secondly the yarn may be cotton blended, there may be a cotton polyester cover. There's no way to fix it.

Q:Can polyester fiber be waterproof?

Waterproof.It is often said that the polyester fiber polyester, polyester synthetic fiber by organic acid and diol which is prepared by spinning the, is the first large current varieties of synthetic fiber.

Q:What's the difference between a biological fiber mask and a silk mask?

Because silk contains 18 kinds of amino acids on human highly nutritional value, is a porous material, good air permeability, good absorbent, the film specifically for the United States and Japan after the operation, wound dressing, wound dressing to use, help wound healing and no stimulation, known as "artificial skin". As a mask, its function is ever a mask can not be done, but it is a very high safety factor, light texture, thin, soft, breathable, transparent, like a second layer of human skin, so the product once available, the industry known as the "five star mask", become a popular trend in the countries and regions in Europe, America, Japan, Hongkong, Taiwan Chinese beauty industry developed.Advantages: thin, docile, good air permeability

Q:What functions can the fiber rotary drum filter play in the sewage treatment process?

A lot of water through the front end of the biochemical transformation can meet other indicators, except for SS, so we need a filtering process to ensure SS standard, and the processing precision is high and the fiber filter rotary flux, less land occupation, low operation cost, has a broad application prospect in this field.

Q:Polyester fiber, polyester, acrylic, spandex have any harm to the body?

However, synthetic fiber (polyester, acrylic, nylon) the moisture absorption rate of only 0.4% to 3%, such as underwear materials, due to its poor hygroscopicity, skin sweat not easy absorption of the fabric and the evaporation of sweat volatile retention in the skin after leaving salt residue, clogged pores, skin irritation easy to cause "chemical dermatitis".

Q:Which is good, MDF or particleboard? Why?

In terms of environmental protection, shaving boards are better. It uses less glue. But the molded board can be made in many different shapes to suit the needs of the European style.

Q:Structural performance difference between polyacrylonitrile and carbon fiber

Carbon fibers are formed by pre oxidation and carbonization of polyacrylonitrile.

Q:Will the material be 100% polyester fabric?

Polyester fiber is a chemical synthetic material. It is available in many clothing materials nowadays. It is combined with cotton components in most clothing
