Bayan shekaru na samarwa aiki, mu kamfanin, Highsun Synthetic Fiber Technologies Co., Ltd., a hankali gano tasirin zafin akwatin zafi akan crimping, ƙarfi da rini na nailan 6.
1. Tasiri kan nailan 6 crimping
A ƙarƙashin yanayin samarwa na ƙaddamarwa na 1.239 sau, D / Y na 2.10 da saurin 700m / min, raguwar raguwa da kwanciyar hankali yana karuwa tare da karuwar zafin jiki a cikin wani kewayon.Wannan shi ne saboda filastik na fiber yana inganta tare da karuwar zafin jiki, wanda ya sa ya zama mai sauƙi.Don haka nailan 6 yana da laushi kuma ya lalace sosai.Koyaya, lokacin da zafin jiki yayi ƙasa da ƙasa (a ƙasa 182 ℃), ƙimar ƙima da kwanciyar hankali na kayan nailan 6 ya zama ƙasa kuma.Filament ɗin yana da taushi kuma mara ƙarfi, wanda ake kira siliki auduga.Lokacin da zafin jiki ya yi yawa (mafi girma fiye da 196 ℃), filament ɗin da aka sarrafa ya zama m kuma yana da ƙarfi.Wannan shi ne saboda zaruruwan suna raguwa a ƙarƙashin matsanancin zafin jiki, yana haifar da fibrils waɗanda ke haɗuwa tare kuma su zama filaye masu tsauri.Don haka raguwar ƙwanƙwasa yana raguwa sosai.
2. Tasiri akan ƙarfin nailan 6
A lokacin aikin samarwa, an gano cewa zafin jiki na akwatin zafi kuma yana da tasiri mai girma akan ƙarfin nailan 6. A karkashin yanayin fasaha na saurin 630m / min, ƙaddamarwa rabo 1.24 sau da D / Y 2.03, karkatar da tashin hankali yana raguwa. kuma tashin hankali mara jujjuyawa shima yana raguwa tare da karuwar zafin jiki, wanda shine saboda laushin fiber a babban zafin jiki.A in mun gwada da ƙananan zafin jiki, ƙarfin yana ƙaruwa tare da karuwar zafin jiki, amma yana raguwa tare da ƙara yawan zafin jiki (193 ℃).Wannan shi ne yafi saboda a ƙananan ƙananan zafin jiki, ƙarfin aiki na ƙwayoyin fiber yana ƙaruwa tare da karuwar yawan zafin jiki, wanda ya rage yawan damuwa na ciki a cikin aiwatar da nakasar thermal, ya sa ya zama mai sauƙi don lalata kuma yana ƙara ƙarfin filament.Koyaya, tare da ƙarin haɓakar zafin jiki, daidaitawar amorphous a cikin fiber yana da sauƙin yankewa.Lokacin da zafin jiki ya kai 196 ℃, zaruruwan da aka samar sun zama m kuma suna da ƙarfi tare da bayyanar rashin kyau.Bayan gwaje-gwaje da yawa, an gano cewa nailan 6 yana da ƙarfi mafi girma lokacin da zafin akwatin zafi ya kasance 187 ℃.Tabbas, yakamata a daidaita wannan gwargwadon matsakaicin saurin lodin nailan POY.Dangane da gogewa, gurɓataccen mai da ƙura za su tsaya a cikin akwatin zafi tare da raguwar tsabtace injin, wanda zai rage tasirin dumama.
3. Tasiri akan nailan 6 rini
Lokacin da zafin jiki a cikin akwatin zafi ya yi ƙasa, nailan 6 yana da ƙananan crystallinity, ƙaƙƙarfan alaƙar rini, da zurfin rini.Akasin haka, yawan zafin jiki na akwatin zafi yana haifar da rini mai haske da ƙarancin rini na nailan 6. Domin yanayin zafin na'urar da aka nuna a wasu lokuta yana karkata sosai daga yanayin da aka auna, lokacin da aka daidaita yanayin zafi zuwa 210 ° C a ainihin samarwa, bayyanar da alamun jiki na nailan 6 suna da kyau, amma tasirin canza launi ba shi da kyau.
