Abubuwa shida na Nailan

01 Tsayayyar Abrasive

Nailan yana da wasu kaddarorin kama da polyester. Bambance-bambancen shine cewa juriya na zafi na nailan ya fi na polyester muni, ƙayyadaddun nauyin nailan ya fi ƙanƙanta da ɗaukar danshi.nailanya fi na polyester. Nailan yana da sauƙin rini. Ƙarfinsa, juriya na abrasive da juriya na gajiya duk sun fi polyester kyau. Naylon zai zama nakasu cikin sauƙi, amma yana da kyakkyawan aikin farfadowa da haɓaka juriya.

Babban elongation na nailan yana sa ya zama mai kyau a jure tasirin lalacewa. Juriya na nailan shine mafi kyau a cikin dukkan zaruruwa, wanda ya ninka na auduga sau 10 kuma ya ninka na ulu sau 20.

02 Takamaiman Nauyi

Daga cikin manyan zaruruwan roba (polyester, nailan, fiber na acrylic da Vinal), takamaiman nauyin nailan shine mafi ƙanƙanta, wanda shine 1.14. Saboda haskensa takamaiman nauyi, nailan ya dace da kayan aiki a tsayi da kuma kan tsaunuka masu tsayi. Hakanan saboda ƙarfinsa mai ƙarfi, ana iya amfani da nailan wajen yin igiya, net ɗin gamawa, yarn sisal mai kyau da “Fiber mai faɗuwa”.

03 Dukiya ta thermal

Lokacin da ake sarrafa nailan, ya kamata a yi la'akari da tasirin zafin jiki akan dukiyar fiber. Lokacin da zafin iska mai zafi ya wuce 100 ℃, ƙarfin asarar nailan a bayyane yake. Wannan shi ne saboda a karkashin amsawar zafi, dazarenkwayoyin halitta za su sami lalatawar sinadarai na oxidative. Gabaɗaya, a ƙananan zafin jiki, ƙarfin nailan ya fi ƙarfi. Domin a ƙananan zafin jiki, kwayoyin suna da ƙananan motsi na zafi kuma dakarun intermolecular suna da karfi.

A dakin da zafin jiki, ƙarfin nailan staple fiber zai iya zama har zuwa 57.33 ~ 66.15cN / tex da ƙarfin nailan high-tenacity fiber na iya zama har zuwa 83.8cN / tex, wanda shine 2 ~ 3 sau da karfi fiye da na auduga fiber. . Bugu da ƙari, karuwar zafin jiki zai haifar da raguwa na nailan. Lokacin da yake kusa da wurin narkewa, raguwa yana da tsanani kuma fiber zai yi rawaya.

04 Kayan Wutar Lantarki

Ƙarfafawar nailan ya yi ƙasa sosai. Don haka a sauƙaƙe za a sami tarin wutar lantarki a lokacin samarwa. Amma lokacin da yanayin zafi na dangi ya karu, ƙaddamarwa yana ƙaruwa azaman aikin ma'auni. Misali, lokacin da yanayin zafi ya canza daga 0 zuwa 100%, ƙimar Nylon 66 zai haɓaka 10.⁶sau. Don haka maganin ciyar da jika kamar fesa hazo a sarrafa nailan zai rage tara wutar lantarki.

05 Ayyukan Shayar da Danshi

Naylon shine fiber na hydrophobic. Amma a cikin macromolecules na nylon, akwai ƙungiyoyi masu rauni da yawa, kamar -C=O-NH-. Kuma a duka iyakar kwayoyin halitta, akwai kuma -NH2 da -COOH kungiyoyin hydrophilic. Sabili da haka, aikin shayar da danshi na nailan ya fi na duk sauran zaruruwan roba, tsammanin Vinal.

06 Abubuwan Sinadarai

Tsarin sinadaran nailan yana da kyau, musamman juriya na alkali. A cikin 10% NaOH bayani, bayan aiki na 10 hours a 85 ℃, ƙarfin fiber rage 5% kawai.

Ƙungiya mafi aiki a cikin macromolecule nailan shine rukunin amide, wanda za a yi amfani da shi a ƙarƙashin wasu yanayi.

Acid na iya yin hydrolyze nailan macromolecules kuma ya haifar da raguwar darajar fiber polymerization. Nailan macromolecules kuma na iya yin ruwa a cikin ruwa sama da 150 ℃. Acid da zafi na iya haifar da hydrolysis na fiber.

Ƙarfin oxidant zai lalata nailan, kamarbleachingfoda, sodium hypochlorite da hydrogen peroxide, da dai sauransu, wanda zai haifar da karyewar sarkar kwayoyin fiber da rage karfin fiber. Haka kuma yadudduka za su yi rawaya bayan bleached da wadannan oxidants. Don haka idan yana buƙatar bleach nailan yadudduka, yawanci ana amfani da sodium chlorite (NaCLO₂) ko rage bleaching wakili.
