Textilefiberclassification:naturalfiberandchemicalfiber.
①Naturalfibersincludeplantfibers,animalfibersandmineralfibers.
AKasvikuituja, kuten puuvillaa, hamppua, hedelmäkuitua.
Beläinkuituja, kuten villaa, kaninkarvaa, silkkiä.
Cmineraalikuituja, kuten asbestia.
②Chemicalfibersincluderegeneratedfibers,syntheticfibersandinorganicfibers.
ARegeneroituja kuituja, kuten viskoosikuitua, asetaattikuitua.
BSynteettiset kuidut, kuten: nylon, polyesteri, akryyli, elastaani, vinyloni, polypropeeni, polykloridi
Epäorgaaniset kuidut, kuten: lasikuitu, metallikuitu jne.
4.Yleisten tekstiilikuitujen tekstiiliominaisuudet:
(1) Villa: kosteuden imeytyminen, elastisuus, kulutuskestävyys ovat hyvät, ei kestä hyönteisiä, happoa ja metallia sitovia väriaineita.
(2) Silkki: hyvä kosteuden imeytyminen, hengittävyys, kiilto ja kulutuskestävyys, sopii happamille ja suorille väriaineille.
(3) Puuvilla: hengittävä, kosteutta imevä, hyvä kulutuskestävyys, hyönteistenkestävä, sopii suoraan, pelkistykseen, atsoon, emäksiseen väliaineeseen, rikkiin ja reaktiivisiin väriaineisiin.
(4) Viskoosikuitu: hygroskooppisuus, hyvä ilmanläpäisevyys, kirkas väri, laaja materiaalilähde, edullinen, luonnonläheinen luonnonkuitu, käytettävät värit ovat sama kuin puuvilla.
(5) Polyesteri: kangas, jäykkä, viileä, hyvä muoto, kulutuskestävyys, mittojen vakaus, helppo pestä käsin kuivaksi, sopii dispergoituihin väriaineisiin, diatsodispersioväreihin, liukeneviin väriaineisiin.
(6) Nylon: erityisen hyvä hankauskestävyys, huono ilmanläpäisevyys, sopii happamille väriaineille ja bulkkiväreille.
(7) Akryylikuitu: hyvä pörröinen, pörröinen, sopii haja- ja kationiväreille.
(8) Vinylon: Paras kosteudenabsorptio, yleensä käytetty köysissä, kalastusverkoissa jne.
(9) Polypropeeni: kevyin rakenne, kulutusta kestävä, kestävä ja ei-pallo.
(10) Kloori:palaa helposti, usein käytetty neulottuina alusvaatteina, pehmo, teollisuussuodatinkangas, työvaatteet jne.
(11) Spandex:korkein joustavuus, suuri venymä, suuri joustavuus, usein käytetty sukkahousuina, mutta se ei ole värillinen ja sillä on pienin lujuus.
