Abstract
The invention relates to a method for spinning aromatic polysulphone yarns by adopting Sirofil fabric. In the method, the Sirofil fabric is adopted to spin with the process parameters as follows: the spindle speed is 8,000-1,000 r/min; the filament pre-tension is 12-16 Cn; the space between the filament and an aromatic polysulphone fiber strand is 8-12 cm; and the twist degree is 600-800T/m. The invention has simple method, low cost and high productivity and is suitable for industrial production; in addition, the invention improves the yarn levelness and the yarn strength, and the obtained yarn has less hairiness.
Description
Technical field
The invention belongs to the spinning field of polysulfonamide yarns, particularly relate to a kind of method that adopts the Seluofle spinning for spinning polysulfonamide yarns.
Background technology
Polysulphonamide fiber is Shanghai City Spinning Science Institute and Shanghai Institute of Synthetic Fiber organic high temperature-resistant fiber that the has independent intellectual property (application number: 200710037799.1) through developing for many years.Virtue sulfone synthetic fibre belongs to aromatic polyamide class exotic material, and the blank of the anti-250 ℃ of grade synthetic fiber of China has been filled up in its appearance.Virtue sulfone synthetic fibre has important purposes on defence and military and modern industry, be the tec fiber that China is badly in need of.From the angle of grand strategy material and industry new material core technology, be put into national Eleventh Five-Year Plan scientific and technological industry major fields guide.But polysulphonamide fiber is owing to have characteristics such as volume resistivity height, curling stability is poor, coefficient of friction is on the low side, causes problems such as spinning processing difficulties, resultant yarn filoplume be more.Therefore the filoplume problem that how to solve spinning key technology, especially its yarn of polysulphonamide fiber has become the bottleneck of industrialization.
Summary of the invention
Technical problem to be solved by this invention provides a kind of method that adopts the Seluofle spinning for spinning polysulfonamide yarns, and this method is simple, and cost is low, and the production efficiency height is suitable for suitability for industrialized production.
A kind of method that adopts the Seluofle spinning for spinning polysulfonamide yarns of the present invention comprises:
Adopt the Seluofle spinning, technological parameter is: ingot speed is 8000～10000r/min, and the long filament pre-tension is 12～16cN, and the spacing of long filament and polysulphonamide fiber yarn is 8～12cm, and the twist is 600～800T/m.
Described long filament is polyester filament, chinlon filament or viscose filament yarn.
A long filament feeding unit is installed in the present invention additional on ring spinning frame, and makes long filament and polysulphonamide fiber yarn keep 8～12cm spacing jointly in front roller nip output, and long filament and polysulphonamide fiber yarn converge at twist triangle zone and be combined into two component yarns.Because the effect of long filament is effectively improved Yarn filoplume, yarn evenness, fault all obviously are better than single thread, and yarn strength, elongation are better than strand.The existence of long filament simultaneously also makes the suffered tension force of fragrant sulfone synthetic fibre yarn reduce greatly, so spinnability improves, and production efficiency is improved.
Beneficial effect
(1) the inventive method is simple, and cost is low, and the production efficiency height is suitable for large-scale production;
(2) the inventive method has overcome the many shortcomings of traditional ring spinning Yarn filoplume, can improve other performance indications such as yarn evenness, brute force again simultaneously; Especially adopt the spinnability that effectively to improve polysulphonamide fiber behind the long filament in addition, both enriched product style, widened Application Areas again by the combination of different material.
