The present invention relates to keep the contraposition class aromatic polyamide fibre and the manufacture method thereof of high strength, high elastic modulus speciality.
Background technology
Fanglun 1414 (below be called contraposition class aromatic polyamide fibre) is to have excellent properties such as high strength, high elastic modulus, high-fire resistance, non-conductive property and non-corrosive, and has the synthetic fiber of excellent properties such as distinctive flexibility of organic fiber and light weight.Owing to possess these specialities, thereby can be used as the reinforcing material of tooth belt that automobile, motorcycle and bicycle tyre, automobile use and conveyer belt etc.And, also can be used for the enhancing and the rope of fiber optic cables.And can be used as armored vest, have the safety gloves that prevents sharp weapon cuttings character, and the protection dress material of Work Clothes etc., utilize the fire-entry suit of its flame-retardant nature etc.
When in these fields, using, except that above-mentioned performance, also require to have stainability, yet, because aromatic polyamide fibre has high crystalline and intermolecular adhesion is strong, compact structure, so, the dyeing difficulty.
Before this, the someone proposes to adopt the colouring method of following method as aromatic polyamide fibre.
Open in the clear 50-12322 communique the spy, the method for proposition is the method that additives such as dyestuff and antioxidant, ultraviolet light screener, fire retardant are spread in the fiber of water swelling.Yet the spy opens the diffusion of dyestuff in fiber that clear 50-12322 communique does not relate to all kinds, does not also have sets forth conditions.Particularly water content is in not explanation of the dyeing situation below 50%.
Open in the clear 54-59476 communique the spy, disclose a kind of per inch that makes and produce that 10 places are above curls, from the method for the position dyeing of buckling.In addition, open in the flat 2-41414 communique the spy, disclosed method is the method that is added with organic dye in spinning solution.In addition, open in the clear 63-145412 communique the spy, disclosed method is contraposition orthotype Nomex, imports tension force when solidifying and relax operation, the method that contacts with dyeing liquor after spinning at once.And opening a kind of method that proposes in the flat 7-258980 communique the spy is that inherent viscosity less than the contraposition class Nomex below the 2.5dl/g, is made under the state of its swelling the method that contacts with dye solution at water.The method that proposes in the Te Kaiping 8-260362 communique is to adopt the fiber swelling agent, uses cationic dyes, the method that dyes in the temperature more than 130 ℃.Te Kaiping 5-209372 communique disclosed method is the method that adopts the DISPERSE DYES of molecular weight below 400 in the temperature more than 160 ℃ copolymerization contraposition class aromatic polyamide fibre to be dyeed.In addition, the spy opens flat 9-87978 communique, spy and opens the method that flat 9-87979 communique proposes and be, contraposition class aromatic polyamide fibre, with after the methyl-sulfoxide isopolarity solution-treated in 200 ℃ of methods of carrying out high pressure dyeing.
Yet above-mentioned spy opens the method for clear 54-59476 communique record, for high-intensity rigidity contraposition class aromatic polyamide fibre, industrially is difficult to reach 10 and curls/above the curling of inch, and be confined to generate staple fibre.The method that Te Kaiping 2-41414 communique proposes is so-called primitive color spinning process, and the special method of opening clear 63-145412 communique record is once not twine immediately after the spinning, the method that contacts with dye solution under tension-free condition.In the where method in office, limit tone as prerequisite with the output of every kind of color.In the method for Te Kaiping 7-258980 communique record, because polymer viscosity is low, the intensity of fiber is low to moderate extremely, does not possess the speciality as the aromatic polyamide fibre of high strength fibre.The method of Te Kaiping 8-260362 communique record relates to a kind of TENSILE STRENGTH, tensile modulus of elasticity all than the scheme of the short fibre yarn of filament yarn difference, therefore, utilize the filament yarn dyeing means of the original high strength of aromatic polyamide fibre, high elastic modulus function then can not use.Te Kaiping 5-209372 communique, spy open flat 9-87978 communique and the special method of opening flat 9-87979 communique record, and special equipment such as polar solvent retracting device and high-temp dyeing be arranged, and therefore, are not common methods.
Before this, under the filament yarn form of the high strength that maintains the aromatic polyamide fibre speciality, high elastic modulus speciality, the after stain method that can adopt multiple color to implement, promptly, after the spinning filament yarn is wrapped on the tube, after operation stops, but the part of cutting moves on to dyeing process, individually each dyeing is carried out the colouring method of multiple color, still be unrealized so far.
Generally speaking, form the filament yarn fiber system yarn operation and, the dyeing process that fiber is dyeed is separated from each other, and can implement by various specialized apparatus and special technical staff.In order to satisfy the strict demand of client to coloured fibre goods color, after fiber is made, operation was once stopped, fiber is transported to dye-works, dye the desired tone of client by special staining technique personnel, this has great importance.
