Kodi mukudziwa "zambiri" za ulusi wa nsalu izi?

Posankha zoyeneransalu ya zovala zako, ndikofunikira kumvetsetsa zamitundu yosiyanasiyana ya ulusi. Polyester, polyamide, ndi spandex ndi ulusi wopangira atatu wotchuka, uliwonse uli ndi mawonekedwe akeake komanso mapindu ake.

Polyester imadziwika chifukwa cha mphamvu zake komanso kulimba kwake. Ndipotu ulusiwu ndi wamphamvu kwambiri kuposa ulusi woterewu, wokhala ndi ulusi wolimba kwambiri kuposa thonje, wamphamvu kuwirikiza kawiri kuposa ubweya wa nkhosa, komanso wamphamvu kuwirikiza katatu kuposa silika. Izi zimapangitsa kukhala chisankho chabwino kwambiri pazovala zomwe zimafunika kupirira kutha nthawi zambiri, monga masewera ndi zida zakunja. Kuphatikiza apo, polyester ndi makwinya komanso kulimba kugonjetsedwa, zomwe zimapangitsa kuti ikhale njira yosamalirira bwino pamavalidwe a tsiku ndi tsiku.

Kumbali ina, nsalu ya polyamide, yomwe imadziwikanso kuti nayiloni, ndiyo yosamva kuphulika pa ulusi utatuwo. Makhalidwe ake amphamvu koma osasunthika amawapangitsa kukhala abwino kwa zinthu zomwe zimafunikira kulimba kwambiri, monga zikwama, katundu ndi zida zakunja. Nayiloni ndi yopepuka komanso yowuma mwachangu, zomwe zimapangitsa kukhala chisankho chodziwika bwino pazovala zogwira ntchito ndi zosambira.

Zikafika pakutambasula, spandex imatsogolera njira. Ndiwotanuka kwambiri pakati pa ulusi atatuwo, wokhala ndi elongation pakusweka kwa 300% -600%. Izi zikutanthauza kuti imatha kutambasula kwambiri osataya mawonekedwe, ndikupangitsa kuti ikhale yofunika kwambiri pazovala zokhala ndi mawonekedwe ndi zovala zogwira ntchito. Spandex imadziwikanso chifukwa cha chitonthozo chake komanso kusinthasintha, kulola kuyenda kosavuta komanso kokwanira.

Pankhani yopepuka, nsalu za acrylic zimawoneka ngati ulusi wopepuka kwambiri. Ngakhale patatha chaka chimodzi chowonekera panja, mphamvu zake zidatsika ndi 2%. Izi zimapangitsa kukhala chisankho chabwino kwambiri pa zovala zakunja ndi dzuwa, chifukwa zimasunga umphumphu ndi mtundu wake pakapita nthawi.

Ndikoyeneranso kudziwa kuti ulusi uliwonse uli ndi mawonekedwe akeake. Mwachitsanzo, ulusi wa polypropylene ndi wopepuka kwambiri mwa ulusiwo, wokhala ndi mphamvu yokoka yeniyeni magawo atatu mwa asanu a thonje. Izi zimapangitsa kusankha kotchuka kwa zovala zopepuka, zopumira, makamaka nyengo yotentha.

Kuphatikiza apo, ulusi wa chlorine ndi womwe sumva kutentha kwambiri pamitundu itatu. Imayamba kufewa ndikuchepera pa madigiri 70 Celsius ndipo imayaka nthawi yomweyo ngati itasungidwa kutali ndi lawi lotseguka. Izi zimapangitsa kuti nsalu ikhale yovuta kwambiri kuwotcha, ndikuwonjezera chitetezo chowonjezera pazovala zopangidwa kuchokera kuzinthu izi.

Mwachidule, kumvetsetsa za polyester, polyamide, ndi spandex kungakuthandizeni kusankha bwino posankha zovala ndi nsalu. Kaya mumayika patsogolo mphamvu, kukana kwa abrasion, elasticity, lightfastness kapena katundu wina, fiber iliyonse imapereka ubwino wapadera kuti igwirizane ndi zosowa zosiyanasiyana ndi zokonda. kusankha ndikosavuta komanso kolimba.
