Polylactic asidhi (PLA)inyowani bio yakavakirwa uye inogona kudzokororwazve yekushatisa yakagadzirwa kubva kune sitachi mbishi zvinhu zvakatorwa kubva kune zvinogonekazve chirimwa zviwanikwa zvakaita sechibage necassava.
Starch mbishi zvinhu zvinoiswa saccharified kuti iwane glucose, iyo inozoviriswa nemamwe madhiri kuburitsa yakakwira-kuchena lactic acid. PLA chibage faibha jira risiri rakarukwa rinobva ragadzirwa nemakemikari kuti rigadzirise imwe molecular huremu hwepolylactic acid. Iine biodegradability yakanaka. Mushure mekushandiswa, pasi pemamiriro ezvinhu chaiwo, inogona kuderedzwa zvachose nehutachiona muzvisikwa, ichibudisa carbon dioxide nemvura pasina kusvibisa zvakatipoteredza. Izvi zvinobatsira zvikuru kuchengetedza zvakatipoteredza.PLA jira risiri rakarukwainoonekwa sechinhu chinochengetedza zvakatipoteredza.
Polylactic acid fiber inogadzirwa kubva kune zvakaomeswa zvekurima zvakadai sechibage, gorosi, uye shuga beet, iyo inoviriswa kuti ibudise lactic acid, uye yobva yanyungudutswa nekunyunguduka. Polylactic acid fiber is a synthetic fiber inogona kudyarwa uye iri nyore kukura. Tsvina inogona kuderedzwa nenzira yechisikigo.
Biodegradable performance.
Polylactic acid fiber raw materials yakawanda uye inogona kushandiswazve. Polylactic acid fibers ine biodegradability yakanaka uye inogona kuparara zvachose kuita kabhoni dhaikisaidhi uye H2O muzvisikwa mushure mekuraswa. Ose ari maviri anogona kuve akagadzirwa elactic acid starch kuburikidza nephotosynthesis. Mushure memakore 2-3 muvhu, simba rePLA fibers richapera. Kana yakavigwa pamwe chete nemamwe marara emarara, inoora mukati memwedzi mishoma. Uye zvakare, polylactic asidhi inoiswa hydrolyzed kuita lactic asidhi neasidhi kana enzymes mumuviri wemunhu. Lactic acid inogadzirwa nemasero uye inogona kuwedzeredzwa nema enzymes kuti ibudise kabhoni dhaikisaidhi nemvura. Naizvozvo, polylactic acid fibers zvakare ine yakanaka biocompatibility.
Kuita kunyura kwemvura
PLA faibha dzine hunyoro hwakanaka hwekutora uye conductivity, zvakafanana nekuderera. Iyo mwando yekunyudza kuita inobatanawo neiyo morphology uye chimiro chefiber. Iyo longitudinal pamusoro pePLA fibers ine mavara asina kujairika uye inoregedza mitsetse, pores kana makatsemuka, ayo anogona nyore kuumba capillary mhedzisiro uye kuratidza yakanaka yepakati absorption, moisturizing uye mvura diffusion zvivakwa.
Kumwe kuita
Iyo ine yakaderera kupisa uye kumwe kunonoka kwemurazvo; Kuita kwekudhaya kwakaipisisa kupfuura akajairwa machira, asingamirire acid uye alkali, uye nyore kuita hydrolyze. Munguva yekugadzira dhayi, kutarisisa kwakanyanya kunofanirwa kubhadharwa kune pesvedzero yeasidhi uye alkalinity; Kushivirira kwakasimba kune ultraviolet nemwaranzi, asi kunowanzo kune photodegradation; Mushure memaawa mazana mashanu ekuratidzwa kwekunze, kusimba kwePLA fibers kunogona kuchengetedzwa kunosvika makumi mashanu neshanu muzana uye kuve nemamiriro ekunze akanaka.
Iyo mbishi yekugadzirwa kwepolylactic acid fiber (PLA) ilactic acid, iyo inogadzirwa kubva kuchibage starch, saka iyi mhando yefiber inodaidzwa zvakare kuti chibage fiber. Inogona kugadzirwa nekuvirisa shuga beet kana zviyo neglucose kuderedza mutengo wekugadzira lactic acid mapolima. High molecular weight polylactic acid inogona kuwanikwa kuburikidza nemakemikari polymerization yelactic acid cyclic dimers kana yakananga polymerization yelactic acid.
Zvigadzirwa zvakaitwa kubva ku polylactic asidhi zvine biocompatibility yakanaka, bioabsorbability, antibacterial uye flame retardancy, uye PLA ine kupisa kwekudzivirira mumapolymer anoshatisa thermoplastic.
Polylactic acid fiber inogona kuodzwa kuita kabhoni dhaikisaidhi uye mvura muvhu kana mumvura yegungwa. Kana yapiswa, haibudisi magasi ane chepfu uye haikonzeri kusvibiswa. Iyo inogara yakasimba ecological fiber. Jira rayo rinonzwa kunaka, rine drape yakanaka, rinoshingirira kumaranzi eUV, rine kushomeka kwemoto, uye kuita kwakanaka kwekugadzirisa. Yakakodzera kune akasiyana fashoni, zvipfeko zvekutandara, zvinhu zvemitambo, uye zvigadzirwa zvehutsanana, uye ine tarisiro yakakura yekushandisa.
