Embodiment 1

[0017] The production process of polyphenylene sulfide resin fiber is as follows: PPS primary fiber-drawing-setting-setting-winding-PPS finished fiber, the following process conditions are used to draft and set the polyphenylene sulfide primary fiber:

[0018] Drafting multiple 3 times

[0019] Tensile speed 200 / min

[0020] Stretching temperature 90°C

[0021] Heat setting temperature 200℃

[0022] The obtained PPS fiber has properties as shown in Figure 1.

Embodiment 2

[0024] The production process of polyphenylene sulfide resin fiber is as follows: PPS primary fiber-drawing-setting-setting-winding-PPS finished fiber, the following process conditions are used to draft and set the polyphenylene sulfide primary fiber:

[0025] Drafting multiple 5 times

[0026] Tensile speed 500m / min

[0027] Stretching temperature 120°C

[0028] Heat setting temperature 250℃

[0029] The obtained PPS fiber has properties as shown in Figure 2:

[0030] After optimizing the above drawing and setting process, the PPS fiber is fully crystallized and oriented, so as to obtain good mechanical properties and thermal stability.

[0031] The PPS fiber produced by the inventive method passes through the Sichuan Provincial Fiber Inspection Bureau and the National Fireproof Building Material Quality Supervision and Inspection Center to the detection of relevant indicators, and the measurement result is compared with the Ryton fiber of Phillipsd...

Abstract

The invention discloses polyphenylene sulfide as-formed fiber drafting forming technology. It uses polyphenylene sulfide spinning technology to produce polyphenylene sulfide resin fiber, and produces PPS finished fiber by drafting, forming, and winding for PPS as-formed fiber. Its technique condition is as follows: drafting multiple is 2-7; speed is 50-500m / min; temperature is 90-160 centigrade degree; heat forming temperature is 180-300 centigrade degree.

Description

Technical field: [0001] The invention belongs to the field of special fiber manufacture. Background technique: [0002] High-performance polyphenylene sulfide has excellent chemical resistance and thermal stability at high temperatures, and has flame retardancy, insulation, radiation resistance and good mechanical properties. In order to expand the scope of use of this material, researchers from various countries have been looking for new methods to make it fiberized. [0003] Chinese patent CN91107114 discloses a process for making composite materials from potassium titanate fiber and polyphenylene sulfide. In the polycondensation kettle, hexaamine dispersant (also used as a solvent for polyphenylene sulfide synthesis) is used to heat and stir Potassium titanate fibers are dispersed under the conditions, then sodium sulfide and p-dichlorobenzene (P-DCB) are added as raw materials, and polyphenylene sulfide (sodium sulfide and p-dichlorobenzene (P-DCB) is produced by polyco...
