01 Abrasive Resistance
Nylon ine zvimwe zvinhu zvakafanana nepolyester. Misiyano ndeyekuti kupisa kwekupisa kwenylon kwakaipisisa kupfuura iyo yepolyester, iyo chaiyo gravity yenylon idiki uye kunyura kwemvura.naironiyakakura kupfuura iyo polyester. Nylon iri nyore kupenda. Simba rayo, abrasive kuramba uye kuneta kuramba zvese zviri nani pane polyester. Nylon inozokanganisa zviri nyore, asi ine yakanaka kudzoreredza kuita uye yakakwirira rebound resilience.
Iyo yakakwira elongation yenylon inoita kuti ive yakanaka mukupokana nekukanganisa kupfeka. Kupfeka kupikisa kwenylon ndiyo yakanakisisa pakati pemafibhi ose, ayo akareba ka10 kupfuura yekotoni uye 20 nguva yakakwirira kupfuura yemvere dzemakwai.
02 Chaiyo Gravity
Pakati pemasimbi makuru ekugadzira (polyester, naironi, acrylic fiber uye Vinal), iyo chaiyo giravhiti yenylon ndiyo idiki, inova 1.14. Nekuda kwekureruka kwayo kwakanangana negiravhiti, naironi inokodzera zvinhu zvekushandisa pakakwirira uye pamakomo marefu. Zvakare nekuda kwekusimba kwayo kwepamusoro, naironi inogona kuiswa mukugadzira tambo, mambure ekupedzisa, shinda yesisal yakanaka uye "hollow cored fiber".
03 Thermal Property
Kana nylon ikagadziriswa, pesvedzero yekushisa pane fiber pfuma inofanirwa kutariswa. Kana tembiricha yemhepo inopisa yadarika 100 ℃, kupera simba kwenylon kuri pachena. Izvi zvinodaro nekuti pasi pekuita kwekupisa, iyofibermamorekuru achava neoxidative kemikari degradation. Kazhinji, pakudzika kwakadzika, simba renylon rakasimba. Nekuti pakudziya kwakadzikama, mamorekuru ane zvishoma zvinofamba zvekupisa uye ma intermolecular forces akasimba.
Pakupisa kwekamuri, kusimba kwenylon staple fiber inogona kusvika 57.33 ~ 66.15cN / tex uye simba renylon high-tenacity fiber inogona kusvika ku83.8cN / tex, iyo 2 ~ 3 nguva yakasimba kudarika iyo yekotoni fiber. . Mukuwedzera, kuwedzera kwekushisa kuchaita kuti nylon iwedzere. Kana yave pedyo nekunyunguduka, iyo shrinkage yakaoma uye fiber ichaita yero.
04 Electrical Property
Iko conductivity yenylon yakaderera zvikuru. Saka pachava nyore kuve nekuunganidza kwemagetsi static panguva yekugadzira. Asi kana tembiricha yakaenzana yenzvimbo yakawedzera, iyo conductivity inowedzera seexponential basa. Semuenzaniso, kana hunyoro hwehukama hwachinja kubva pa0 kusvika ku100%, conductivity yeNylon 66 ichawedzera gumi.6nguva. Saka kunyorova kurapwa semhute yekupfapfaidza mukugadzirisa naironi kunoderedza kuunganidzwa kwemagetsi akamira.
05 Kunyorova Kwekuita Kuita
Nylon is hydrophobic fiber. Asi mune nylon macromolecules, kune akawanda mashoma mashoma hydrophilic mapoka, se -C = O-NH-. Uye pamativi ese ari maviri emamorekuru, kune zvakare -NH2 uye -COOH hydrophilic mapoka. Naizvozvo, kuita mwando kunyura kwenylon kwakakwira kupfuura kwemamwe ese mafiber ekugadzira, tarisira kuVinal.
06 Chemical Property
Iko kugadzikana kwemakemikari yenylon yakanaka, kunyanya iyo alkali kuramba. Mu10% NaOH mhinduro, mushure mekugadzirisa kwemaawa gumi pa85 ℃, simba refiber rinoderera 5% chete.
Iro boka rinonyanya kushanda munylon macromolecule iboka reamide, iro rinozoitwa hydrolyzed pasi pemamwe mamiriro.
Acid inogona hydrolyze nylon macromolecules uye kukonzera kudzikira kwedhigirii refiber polymerization. Nylon macromolecules anogona zvakare hydrolyze mumvura pamusoro pe150 ℃. Acid uye kupisa zvinogona kukonzera iyo hydrolysis ye fiber.
Yakasimba oxidant inokuvadza nylon, sengebleachinghupfu, sodium hypochlorite uye hydrogen peroxide, zvichingodaro, izvo zvinokonzeresa kuputsika kwefiber molecular chain uye kuderedza simba refiber. Zvakare machira anozoita yero mushure mekucheneswa neaya oxidants. Saka kana ichida kubleach machira enaironi, panowanzo shandiswa sodium chlorite (NaCLO2) kana kuderedza bleaching agent.
