For example: after the jelly yarn spun with dimethyl sulfoxide\/water (8\/2) mixed solvent is stretched by 48 times, the fiber with the strength of 21.36cN\/dtex can be obtained. High-strength and high-modulus polyvinyl alcohol fibers with a strength of 39cN\/dtex and a modulus of 925.6cN\/dtex can be obtained by jelly spinning from syndiotactic polyvinyl alcohol with ultra-high degree of polymerization. The strength of the polyvinyl alcohol super-strength filament obtained by the jelly spinning technology of Japan Kuraray Company reaches 18cN\/dtex. In the wet spinning technology, by adding borate to the solution, crosslinking points are formed during the coagulation process, so that the molecular chains with lower density in the spun fibers are entangled, so that high-stretching can be carried out. Fibers spun by this technique have a strength of 19.7 cN\/dtex and a modulus of 385 cN\/dtex (50GPa)<\/p>\n<p><img fetchpriority=\"high\" decoding=\"async\" class=\"aligncenter size-full wp-image-856\" src=\"https:\/\/www.joyforce.com\/wp-content\/uploads\/2024\/02\/3-4.png\" alt=\"\" width=\"761\" height=\"594\" srcset=\"https:\/\/www.joyforce.com\/wp-content\/uploads\/2024\/02\/3-4.png 761w, https:\/\/www.joyforce.com\/wp-content\/uploads\/2024\/02\/3-4-300x234.png 300w, https:\/\/www.joyforce.com\/wp-content\/uploads\/2024\/02\/3-4-15x12.png 15w, https:\/\/www.joyforce.com\/wp-content\/uploads\/2024\/02\/3-4-600x468.png 600w\" sizes=\"(max-width: 761px) 100vw, 761px\" \/><\/p>","protected":false},"excerpt":{"rendered":"<p>A fibra de polivinil\u00e1lcool de alta resist\u00eancia \u00e9 uma fibra obtida por fia\u00e7\u00e3o em gelatina ou fia\u00e7\u00e3o \u00famida e alto alongamento de polivinil\u00e1lcool com alto grau de polimeriza\u00e7\u00e3o.
