Background
The heterocyclic aramid (aramid III fiber) is para-aramid with aromatic heterocyclic rings on the main chain, and the typical aromatic heterocyclic ring is a benzimidazole ring. According to theoretical calculation, the tensile strength of the fiber formed by ternary condensation polymerization of p-phenylenediamine, terephthaloyl chloride and benzimidazole diamine can reach 4.5-5.5 GPa. And has high thermal stability, and the decomposition temperature of the wholly aromatic polyamide fiber can reach 550 ℃. The aramid fiber reinforced resin matrix composite material has a wide application range and plays an important role in a plurality of fields such as aerospace, military bullets, sports equipment, automobiles, buildings and the like.
However, the heterocyclic aramid fiber needs to obtain higher mechanical properties, and the diameter and the larger stretching ratio of the monofilaments in the bundle fiber must be controlled in the spinning preparation process, so that the orientation degree and the regularity of a large molecular chain are increased. Although the performance of the finished fiber is excellent, the bundle fiber is rough in surface state and has the defects of cutting, entanglement and even breakage in the process of processing into fabrics in the later period.
In the existing production process, in order to prevent the surface of the bundle yarn from being rough and reduce the external tension of the broken yarn, an antistatic agent is generally added on the surface of the raw yarn, so that the cohesive force of the bundle yarn is increased and the spinning abrasion is reduced. However, in practice, since the antistatic agent is carbonized and decomposed after the precursor is subjected to a high-temperature heat treatment (typically, a heat treatment at 400 ℃), the reduction of the fiber filaments is insignificant and impurities after carbonization and decomposition are present in the obtained fiber product. When the fabric is processed into a fabric at a later stage, the surface strength of the fabric is not ideal, the conversion rate of the strength is not high, and impurities attached to the surface have certain influence when the fabric is combined with resin to prepare a composite material.
