1 overview

Fragrant black silk ribbon is fiber of special type of a kind of high-tech, it owns admirable mechanical property, stable chemistry follows good mechanical quality. Its full name is " scent a group of things with common features gets together phthalein amine fiber " , 1974, american trade union (FTC, for U. S. The abbreviate of Federal Trade Commission) name them for " Aramid Fibers" , is its are defined: ? The phthalein amine catenary of distant admonish?5% (one CONH one) follow photograph of two benzene annulus to join directly [U 1. China names them for fragrant black silk ribbon, its full name also can simplify for " fiber of fragrant phthalein amine " . It has a series of product.

2 fragrant fishing line are main the function of breed

Fragrant black silk ribbon follows get together phthalein amine fiber (like nylon 66 fiber) quite, because be in macromolecule long chain with scent radical was replaced adipose base, of catenary flexible reduce, tigidity increases, be being mirrorred in fiber function angle is the gender can enhance heat-resisting, initiative model quantity increases apparently. 2.1 counterpoint fragrant black silk ribbon

Contrapuntal fragrant black silk ribbon succeeds at was being developed 1971, cast life to produce second year. Abbreviation PPTA(is Poly the abbreviate word) of one Phenylene Fere Phthalamide of one P.

Counterpoint highlights a characteristic in function of fragrant black silk ribbon is high strenth is measured with high standard. Its initiative model measures the 4 times; that its intensity is the silk of polyester fibber industry with higher intensity for the 3 times; of steel, the 4 one 10 times; that is silk of polyester fibber industry gets together phthalein amine fibrous 10 times above. Its stability is first-rate, below 150 ℃ temperature shrinkage is 0. It still can last below high temperature higher intensity, if be below 260 ℃ temperature,still can last 65% of primary strength. It is good to balata adhesiveness, it still has the; of curtain line fiber that is photograph comparing ideal low density, admirable decrease malleability, wear-resisting, impulse withstand, fight exhaustion, low expand, low heat conduction, do not light, not the outstanding hot property such as frit and good interpose report performance [2, 312.2 Wei Fangguan

Wei Fangguan began to consider 1956 between, change at completing Z course of study 1967, abbreviation MPIA(is Pol, the abbreviate word) of one Phenyleneisophthalamide of one M.

The characteristic is being highlighted in Wei Fangguan function is hear resistance between good, flame retardant with wear-resisting corrode sex. It applies 1 000 H continuously in 260 ℃ temperature hind, its intensity still can last of primary strength " %; falls in 300 ℃ high temperature, apply 7d, still can last its 0 intensity make an appointment with the 50%; of former radian for 500 ℃ ; it burns hard in blaze, after leaving blaze, have from extinguish sex. The action with its ability acerbity great majority, alone follows hydrochloric acid for long, nitric acid or vitriolic contact, intensity just is reduced somewhat. To alkaline stability also good, just cannot change the alkali such as sodium to be contacted for a long time with oxyhydrogen. In addition, the stability that it waits for to bleacher, reducer, organic dissolvent is first-rate also. It still has good radiation resistance can, in the X of 50 KV the illuminate of one ray falls, 250 H of all previous classics, its intensity still can last 49% of primary strength. Its insufficient part follows polyamide fibber exactly like, poorer to solar stability, hard coloring.
