Hoʻomākaukau ʻia ka PA56 biobased mai nā kumuwaiwai hou e like me ka kulina a me ka palaoa ma ke ʻano microbial a laila polymerized me ka waikawa adipic. Ua like kona mau waiwai me nā PA6 a me PA66, a hiki ke hoʻohana ʻia i loko o ka lole, nā plastics ʻenekinia a me nā ʻoihana ʻē aʻe. Ma ke ʻano o ka hopena o ke kaiapuni, hiki iā ia ke pani i kekahi mau huahana fiber polyamide i hoʻokumu ʻia i ka petroleum.

Nā waiwai kino o

ʻO ka nui o ka PA56 olaola ma ke ʻano maʻamau he 1.12 ~ 1.14 g/cm3, nona nā waiwai mechanical maikaʻi. Hiki ke hoʻokumu ʻia nā pilina hydrogen ma waena o nā ʻāpana kaulahao o ke kaulahao, a ua like ka ikaika o ka haki me ko PA6. Ke 3 ~ 3.5 ka nui o ka hoʻolālā ʻana o ka filament PA56 biobased me nā viscosities like ʻole, e hoʻonui ka ikaika o ka haki a me ka modulus mua me ka hoʻonui ʻana o ka nui o ka hoʻolālā ʻana. Aia ka hui amide hydrophilic i loko o ka fiber, e hāʻawi ana i ka fiber i kekahi hygroscopicity, ʻaʻole maʻalahi ka hana ʻana i ka uila static, a he palupalu kona manaʻo. ʻO ka nui o ka hoʻomoʻa wai saturated o ka PA56 bio-based he 14%, ʻoi aku ka kiʻekiʻe ma mua o PA6 a me PA66, no laila ʻoi aku ka maikaʻi o ka ʻoluʻolu i ke komo ʻana a me ke komo ʻana.

Ka hana hoʻoluʻu

Hiki ke hoʻoluʻu ʻia nā olonā PA56 biobased me nā dyes waikawa nāwaliwali, nā dyes reactive a me nā dyes disperse me ka polarity ikaika. I loko o kona ʻano molekala, ʻo ka nui o nā ʻātoma kalapona ma nā ʻāpana kaulahao nui e like me PA6, PA66, ʻoi aku ka liʻiliʻi akā ʻoi aku ka nui o ka PA66 diamine me kahi ʻātoma kalapona hoʻokahi, hiki ke hana mua i ka pilina hydrogen i nā ʻāpana PA66 ʻo ia ke kūlana manuahi o ka hydrogen a me ka oxygen, no laila e hoʻonui ana i ka locus dyeing PA56, a me ka hoʻohui ʻana o ka carbonyl amino o ka fiber a me ka omo wai, a me ka neʻe ʻana i loko, e hana i ka dyeability a me ka palupalu o PA56.

Ke lawe nei i ka hana

Loaʻa i ka fiber PA56 i hoʻokumu ʻia i ka bio nā waiwai kino a me nā kemika maikaʻi loa, a he manaʻolana ākea kona hoʻohana ʻana ma ke kahua o ka hoʻohana ʻana ma muli o kona palupalu, anti-pilling, omo wai a me ka flame retardant. ʻO ke ʻano asymmetric ma waena o nā molekala e hoʻohālikelike ai iā PA56 i ka palupalu me ka hulu hipa me ka ʻole o ka hoʻopilikia ʻana i kona ikaika a me ke kūpaʻa ʻana i ka ʻaʻahu.

Ke kūlana noi

ʻO nā olonā PA56 i hoʻokumu ʻia i ka bio i kēia manawa e komo pū me ka filament, staple a me nā olonā composite, ma waena o ia mea e komo pū ana ka filament me ka filament pre-oriented (POY), ka filament textured stretch (DTY) a me ke kaula i hoʻolōʻihi piha ʻia (fdy).ʻAʻole nui ka lauoho o nā olonā paʻa Bio - PA56 a he laumania a palupalu hoʻi e ulana. Ua like nā waiwai kumu o PA56 me nā polyamides kuʻuna, a hiki ke hoʻohui ʻia me ka hulu hipa, ka fiber cellulose (pulupulu, fiber viscose, tiansi TM), ka fiber polyacrylonitrile, ka fiber acetate, polyester fiber, etc., nona kekahi mau manaʻolana hoʻohana ma ke kahua o ka hoʻohana ʻana. He palupalu maikaʻi ko PA56 a hiki ke hoʻonui i ka ikaika o ka hilo i ka wā e hui pū ʻia me ka hulu hipa.

Eia kekahi, hiki ke hoʻohana ʻia ʻo PA56 bio-based ma ke ʻano he mea maka no nā lole ʻoihana, nā lole koa, nā plastics ʻenekinia, nā kiʻiʻoniʻoni ʻōpala meaʻai, a pēlā aku. Hiki ke hana ʻia ʻo PA56 i loko o ka olonā i hoʻonui ʻia me ka ikaika a me ka hygroscopicity ʻoi aku ka maikaʻi ma mua o PA6 a me PA66, ʻoi aku ke kiʻekiʻe o ka pomeness a ʻoi aku ka maikaʻi o ka flame retardant ma mua o PA6 a me PA66, hiki ke hoʻohana ʻia no ka ulana ʻana i nā kāpeti. Ma ke kahua o ka hoʻohana ʻoihana, hoʻohana nui ʻia ia ma ke ʻano he lole kaula, hoʻohana ʻia ma ke ʻano he lole mōlina o nā huahana rubber e like me nā kaila, ka silika ʻupena lawaiʻa a me ke kaula etc. Ma ka lole koa, hiki ke hoʻohana ʻia no ka hana ʻana i ka parachute, ka halelewa, ka ʻeke moe, a pēlā aku.

No ka ʻike hou aku, e ʻoluʻolu e hoʻolohe i ka "hana a me ka hoʻopili ʻana o ka fiber kemika bio-based PA56", 2019 pukana 8, alakaʻi lole.
