Cov ntaub ntawv muaj skyrocketed. Puas yog daim pawm, ntaub so tes thiab ntaub so ntub tsis nce nqi?

Vim muaj ntau yam laj thawj, cov laj kab kev lag luam chemical tau nce siab, thiab tus nqi ntawm kaum tawm ntawm cov khoom siv tshuaj lom neeg tau nce siab. Txoj kev lag luam huv khoom lag luam tseem tseem faus rau xyoo no thiab cuam tshuam ncaj qha.

Ntau tus neeg muab khoom siv ntawm cov khoom siv nyoos thiab ntu (nrog rau cov ua cov ntawv polymers, spandex, tsis yog-cov ntaub, thiab lwm yam) hauv kev lag luam tu cev tau tshaj tawm tus nqi nce. Cov laj thawj tseem ceeb rau qhov nce yog qhov tsis txaus ntawm cov ntaub ntawv nce toj los yog cov nqi nce ntxiv tsis tu ncua. Qee tus txawm hais tias ua ntej tso ib qho kev txiav txim Yuav tsum rov sib tham.

Coob tus neeg tau xav tias: cov nqi nce toj nce, cov nqi yuav nce daim ntawv los ntawm cov neeg lag luam tiav lawm yuav nyob deb dhau los?

Muaj qee qhov tseeb rau qhov kev xav no. Xav txog cov qauv thiab cov ntaub ntawv raw ntawm cov pawm, cov ntawv so huv si, thiab cov ntaub so ntub.

Cov ntaub ntub dej ntau yog cov ntaub tsis-ntaub, thaum cov ntaub tiag thiab cov ntaub so tes feem ntau muaj peb qho loj: txheej saum npoo, txheej txheej thiab hauv qab txheej. Cov txheej txheem loj no muaj qee qhov siv tshuaj lom neeg.

1. nto txheej: tsis-woven npuag nqe nce

Cov ntaub so tsis-ntaub tsis yog tsuas yog cov khoom siv saum npoo ntawm cov ntaub qhwv pawj thiab ntxuav muag huv xwb, tab sis kuj tseem yog cov ntaub ntawv tseem ceeb ntawm cov ntaub so ntub. Cov ntaub uas tsis muaj cov ntaub siv hauv cov khoom siv huv pov tseg yog ua los ntawm cov tshuaj fiber ntau nrog rau polyester, polyamide, polytetrafluoroethylene, polypropylene, carbon fiber, thiab iav fiber. Nws tau tshaj tawm tias cov ntaub ntawv tshuaj no tseem nce ntxiv hauv tus nqi, yog li tus nqi ntawm cov ntaub qhwv tsis-qhwv yuav tau sawv nrog nws cov ntws los, thiab tib qho laj thawj, cov khoom tiav ntawm cov khoom pov tseg tsis huv yuav tseem sawv.

2. Kev nqus txheej txheej: tus nqi ntawm cov khoom nqus SAP nce ntxiv

SAP yog cov khoom siv tseem ceeb ntawm cov txheej txheej ntawm cov pawm ntawm cov pawm pawm thiab hnab ntxuav tes huv si. Macromolecular dej-nqus cob yog cov polymer uas muaj dej-cov yam ntxwv uas yog polymerized los ntawm hydrophilic monomers. Qhov feem ntau thiab pheej yig tshaj li cov monomer yog cov kua qaub, thiab cov roj ntsha muaj los ntawm kev tawg ntawm cov roj av. Tus nqi ntawm roj av tau nce, thiab tus nqi ntawm cov kua qaub kua qaub Tom qab sawv siab, SAP yuav nce siab.

3. hauv qab txheej: nqi nce ntawm khoom tawg yooj yim polyethylene

Hauv qab txheej ntawm cov ntaub pawm thiab hnab ntxuav tes huv si yog cov yeeb yaj kiab sib xyaw, uas yog cov xov paj ntawm cov pa hauv qab thiab cov ntaub tsis-ntaub. Nws raug tshaj tawm tias breathable hauv qab zaj duab xis yog cov yeeb yaj kiab yas tsim los ntawm polyethylene. (PE, ib qho tseem ceeb ntawm cov yas, yog hluavtaws los ntawm polyethylene Polymer cov ntaub ntawv.) Thiab ethylene, raws li cov khoom siv petrochemical siv, feem ntau yog siv los ua cov khoom siv yas polyethylene. Cov roj ua kua roj yog ua kom pom qhov nce siab, thiab tus nqi ntawm cov pa breathable siv polyethylene ua cov khoom siv raw yuav nce raws li tus nqi ntawm polyethylene nce.

Tus sawv ntawm tus nqi ntawm cov ntaub ntawv nyoos yuav zam kev mob siab rau tus nqi ntawm cov khoom tiav cov tuam ntxhab. Hauv qab no lub siab, tsis muaj ib yam dab tsi ntau tshaj ob qhov kev tshwm sim:

Ib qho yog cov neeg ua tiav cov khoom lag luam txo cov kev yuav khoom ntawm raw cov khoom txhawm rau kom txo qis siab, uas txo lub peev xwm ntau lawm ntawm cov pawm ntau;

Qhov thib ib yog cov tuam txhab ua tiav cov khoom lag luam qhia tawm lub siab ntawm cov neeg sawv cev, khw muag khoom thiab cov neeg siv khoom.

Txawm li cas los xij, tus nqi nce siab ntawm lub khw muag khoom kawg zoo li kev tsis pom zoo.

Yog kawg, cov hais los saum no tsuas yog twv xwb. Qee tus neeg xav tias nthwv dej ntawm tus nce nqi yuav tsis ruaj, thiab lub davhlau ya nyob twg tseem muaj khoom muag los txhawb, thiab tus nqi nce ntawm cov khoom tiav yuav tsis tuaj. Nyob rau tam sim no, tsis muaj cov khoom lag luam tiav tau muab cov ntawv ceeb toom nce nqi.
