Zvakadini Unoziva NezveElastane shanu Dzinowanzo shandiswa?

Tsanangudzo ye elastane

Elastane ndiyo dhizaini ine kureba kwepamusoro uye kusimba.Tsanangudzo yemhando yepamusoro ndeye: "Rudzi rwefiber iyo patembiricha yekamuri, zvinhu zvinodzokororwa zvakatambanudzwa kusvika kaviri kureba kwayo kwepakutanga, uye mushure mekushushikana kwaburitswa, inogona kukurumidza kudzorera kuhurefu hwepakutanga."Uye kune polyurethane zvinhu, inoreva rudzi rwefiber iyo yakatambanudzwa kune yepakutanga kureba katatu, uye mushure mekumanikidzwa kusunungurwa, inogona kukurumidza kudzorera kuhurefu hwepakutanga.Mukuwedzera, munyika dzakasiyana nematunhu, kune dzimwe tsanangudzo.

Pakati pezvizhinji zvezvigadzirwa zvakasiyana-siyana zvine mabasa akasiyana, elastane, se "indasitiri yekubuda kwezuva", inoita basa risingadzokerike muzvinhu zvakadai sekupfeka kunyaradza, kupfava uye kudziya kwembatya nekupa munhu kunzwa kwakanaka kubata, uye nekudaro inogara yakagadzikana munzvimbo. indasitiri yemachira pasi rose.Kunze kwezvo, yanga iri tsika isingadzivisiki yekupa machira emucheka ane elasticity muindasitiri yemachira.

Mhando dze common elastane

1. Alkene mhando elastane (shinda yerabha)

Diolefins elastane inowanzozivikanwa seshinda yerabha kana shinda yarastiki, kureba kwayo kunowanzova pakati pe100% kusvika 300%.Icho chikuru chemakemikari chikamu chayo sulfide polyisoprene.Iyo ine yakanaka yepamusoro-tembiricha kuramba, asidhi uye alkali kuramba, kupfeka-kusagadzikana uye mamwe makemikari uye emuviri zvimiro, ayo anoshandiswa zvakanyanya mumasokisi, ribbed cuffs uye mamwe maindasitiri ekuruka.Rubber shinda imhando ye elastane inoshandiswa mukutanga.Nekuti inonyanya kugadzirwa kuita shinda yakaoma, kushandiswa kwayo mukuruka machira kushoma.

2. Polyurethane fiber (spandex)Polyurethane elastane inoreva rudzi rwefiber yakagadzirwa neblock copolymer ine polycarbamate sechikamu chikuru.Spandex ndiyo yekutanga kugadzirwa uye inonyanya kushandiswa elastane ine yakakura kwazvo kugadzira tekinoroji.

3. Polyether ester elastane

4. Polyolefin elastane (DOW XLA faibha)

5. Composite elastane (T400 faibha)
