Dab tsi yog qhov yuav tsum tau rau lub hnab sab hauv thaum peb yuav tshuaj yej hnab? Nws yog qhov zoo dua los sivpob kws fiber tshuaj yej hnab(tus nqi ntawm pob kws fiber tshuaj yej hnab yog siab dua li ntawm PET nylon). Vim cov pob kws fiber ntau yog cov khoom siv hluavtaws uas hloov mus rau hauv lactic acid los ntawm fermentation thiab tom qab ntawd polymerized thiab spun. Nws yog ntuj, ib puag ncig tus phooj ywg thiab degradable, thiab tuaj yeem tiv taus 130 celsius degree siab kub. Txawm tias siv dej kub npau npau ntawm 100 degrees yuav tsis muaj teeb meem. Ntxiv mus, pob kws fiber ntau yog degradable thiab muaj txiaj ntsig zoo rau ib puag ncig.
Yog li yuav ua li cas txheeb xyuas cov khoom ntawm lub hnab tshuaj yej koj yuav? Raws li tau hais los saum toj no, lub hnab tshuaj yej tam sim no yog ua los ntawm cov ntaub tsis-woven, nylon, pob kws fiber ntau thiab lwm yam ntaub ntawv.
Tsis-woven tshuaj yej hnabyog ua los ntawm polypropylene. Ntau lub hnab tshuaj yej yog ua los ntawm cov ntaub tsis-woven. Yog tias lawv ua tau raws li cov qauv, lawv txoj kev nyab xeeb kuj tuaj yeem lav tau. Qhov tsis zoo yog qhov kev xav ntawm lub hnab tshuaj yej tsis muaj zog thiab cov dej permeability tsis zoo. Muaj cov khoom tsis zoo hauv cov txheej txheem tsim khoom ntawm qee cov ntaub tsis-woven, uas tuaj yeem raug tso tawm thaum lub sijhawm brewing.
Nylon tshuaj yej hnab muaj zog toughness thiab tsis yooj yim rau tsim kua muag, thiab lub mesh yog loj. Qhov tsis zoo yog tias thaum brewing tshuaj yej, yog tias cov dej kub siab tshaj 90 ℃ rau lub sijhawm ntev, nws zoo li yuav tso cov khoom tsis zoo. Txoj kev yooj yim tshaj plaws los ua cov hnab nylon tshuaj yej yog hlawv lawv nrog lub teeb. Cov hnab nylon yog dub tom qab hlawv. Nws tsis yooj yim los tsim kua muag.
Ib yam li pob kws fiber ntau, cov xim ntawm cov tshauv tom qab hlawv yog cov xim ntawm qee cov nroj tsuag, thiab cov pob kws fiber ntau yog yooj yim rau torn.
