It's called "tripoli" and it's called "dachron." when it appeared in hong kong's market, it was translated in cantonese as “yes, it is cool” or “yes, it is fine” to the effect that it is known as “yes, it is cool”。
It is the simplest of the three synthetic fibres and relatively cheap. Added to it are the characteristics of solid and durable, flexible, non-transformable, corrosive, insulating, broad-spreading, easy to wash dry。
Organizational structure
Chemical structure
The basic component of the detergent is polybiphenyl dimethylether, molecular ho-h2c-h2c-o
-oc-ph-cooch2ch2o-
N polyester fibres (pet), known as polyester fibres (pet) due to the presence of large quantities of esters in the molecular chain, with long-chain molecules having a chemical structure of h(och2coco) noch2ch2hoh, with relative ester molecules for fibres generally ranging from about 18,000 to 25,000, lower mammograms and higher industrial scrubbers. In fact, there are also a small number of monomer and low polymers. These low-polymers are less polymeric and exist in circular form. Polybiphenyl diethyl ether may be condensed by the direct esterization of ethyl phenylenediate 9bhet。
It consists of short-fat hydrocarbon chains, esters, benzene rings, endol hydroxyl radicals, in terms of scrubber molecules. There are no other polar cells in the scrubbers except for the presence of two endol hydroxyl radicals, which makes the scrubbers very watery. The detergent molecule contains about 46% esters, esters can undergo hydrolysis, thermal fissures at above 200°c and, in the case of strong alkalis, soaps, which reduce the degree of polymerization, and detergent detergent powders of less than 100°c have no impact on the detergent; the scrubber molecules also contain fatty hydrocarbons chains, which give the scrubber molecules some degree of corrosiveness, but since there are phenyl rings in the scrubber molecules that cannot be internally rotated, they are largely rigid and the molecular chain is easily linear. As a result, the mulching molecules are easy to form crystallized under these conditions, and their crystallity and orientation are therefore high。
Physical structure
The morphological structure observed in microscopes with a molten legal system has circular cross-sections and no special vertical structure. The filamental fibre tissue can be observed under the electron microscope
Alien fibres can change the elasticity of fibres, give them special agglomeration and laxity, and improve their hugging and covering, as well as their anti-balls and the reduction of static power. For example, triangle fibres have a flash effect; pentaleaf fibres are fat and luminous, have a good sense of hand and are resistant to the ball; and mid-to-air fibres are warm because of their internal cavity, low density and internal heat。
Convergence structure
The thickness of the pyrotechnic crystals, measured by electron distillation, is about 10 nm, while the length of the pyrotechnic mono-matrix is 1. 075 nm, which is therefore considered equal to the single-base length of the nine pyrotechnic molecules. However, the condensed large molecular chain length is about 1. 075*130 (average aggregate degree) = 140nm, and thus can be seen to be cleaned the crystal large molecular chain must have a folding chain structure. Collapse may occur at the-ch2-ch2-chain because the chain is soft and easy to fold。
In addition, it is possible to form crystallines (pre-fibre crystals) as a result of the washing of large molecules. It can be seen that co-existing chain crystals and original crystals exist within the scrubbers. The two crystal ratios vary according to the tensile and thermal conditions。
High intensity. Short fibre strength 2. 6-5. 7 cn/dtex and high power fibre 5. 6-8 cn/dtex. It has essentially the same wet state strength as the dry state, due to its low humidity. The impact-resisting strength is four times greater than the strength of the radon and 20 times higher than that of the glue fibre。
2. Flexibility is good. Effort close to wool can be recovered almost entirely when stretching 5-6 per cent. Wrinkle tolerance exceeds other fibres, i. E. Fabrics are not wrinkled and have good size stability. The elastic model is 22-141cn/dtex, two to three times higher than that of qin. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 。
3. Thermal scrubbers are formed by the melting system, and fibres that are formed can then be melted with heat and form thermal plastic fibres. The melting point of the scrubbers is higher, and the heat is smaller than the heat, and therefore the heat resistance and insulation of the scrubber fibres is higher. It's the best in synthetic fibres。
