Yintoni umahluko phakathi kwee-nonwovens ezisontiweyo kunye nee-nonwovens ezisontiweyo | JINHAOCHENG

Yintoni umahluko phakathiizinto ezingelukiweyo ezisontiweyokunye nee-nonwovens ezisontiweyo, kwaye zeziphi iimpawu eziphambili? Namhlanje, makhe sifumanise ngayo.

Ingcamango ye-Spunlaced nonwovens: ii-spunlaced nonwovens, ezaziwa ngokuba zii-spunlaced nonwovens, ezaziwa ngokuba yi-"jet net into cloth". Ingcamango "yokwenza ilaphu nge-jet spray net" ivela kubuchwepheshe be-acupuncture boomatshini. Okubizwa ngokuba yi-"jet net" kukusetyenziswa kwamanzi anoxinzelelo oluphezulu ukugqobhoza kwi-fiber net, ukuze iifayibha zibhide omnye komnye, ukuze ii-spunlaced nonwovens zokuqala zikhulule i-fiber net zibe namandla athile kunye nesakhiwo esipheleleyo.

Inkqubo yayo yetekhnoloji

Ukulinganisa ifayibha, ukuxuba-ukukhulula kunye nokususa ukungcola-ukudibanisa i-mechanical messy carding kwi-net-pre-matering ye-fiber mesh-water needle entanglement-unyango lomphezulu-uvavanyo lokomisa-ukuhlolwa kwe-coiling-ukupakisha kwindawo yokugcina.

Isixhobo sokutshiza nge-jet net sisebenzisa ukuhamba kwamanzi okuxinzelelwe ngamandla aphezulu kwabavelisi belaphu elingalukwanga ngesantya esiphezulu ukwenza imicu ekwi-fiber net ihlengahlengiswe, ijikeleziswe, kwaye ibe yilaphu elingalukwanga elinesakhiwo esipheleleyo kunye namandla athile kunye nezinye iimpawu. Iimpawu zomzimba zale ngxowa ingalukwanga nge-spin yahlukile kwezo ze-nonwovens eziqhelekileyo ezibhobozwe ngenaliti, kwaye zezona kuphela ezingalukwanga ezinokwenza imveliso yokugqibela ifane nelaphu ngokwesiphatho kunye neempawu ze-nonwovens ze-fiber ezicolekileyo kakhulu.

Ukuphakama kwe-spunlace

Akukho kukhutshwa kwe-fiber web kwinkqubo ye-spunlacing, ngaloo ndlela kuphucula ukudumba kwemveliso yokugqibela; ukuthamba okungokwemvelo kwe-fiber net kugcinwa ngaphandle kokusebenzisa i-resin okanye i-adhesive; ukuthembeka okuphezulu kwemveliso kuthintela ukwenzeka kwemveliso ethambileyo; i-fiber web inamandla aphezulu oomatshini, ukuya kuthi ga kwi-80%-90% yamandla elaphu; i-fiber web inokuxutywa nayo nayiphi na intlobo ngeentlobo zeefayibha. Ngokukodwa, kufanelekile ukukhankanya ukuba i-spunlaced fiber net inokudityaniswa nayo nayiphi na ilaphu elisisiseko ukwenza imveliso edibeneyo. Iimveliso ezinemisebenzi eyahlukeneyo zinokuveliswa ngokweendlela ezahlukeneyo zokusetyenziswa.

Iingenelo zelaphu elisontiweyo:

1. Ilaphu elithambileyo nelilungileyo.

2. Amandla alungileyo.

3. Ine-hygroscopicity ephezulu kwaye i-hygroscopicity ikhawuleza.

4. Ubushushu obuphantsi.

5. Ukuhlanjwa.

6. Akukho zongezo zamakhemikhali.

7. Inkangeleko ifana neyempahla elaphu.

Ithemba lelaphu elisontiweyo

Ngenxa yeenzuzo zelaphu elinolukiweyo, liye laba yinkqubela phambili yezobuchwepheshe ekhawulezayo kwishishini elingelona elenziweyo kwiminyaka yakutshanje. Indlela yophuhliso lwe-nonwovens kukutshintsha ilaphu kunye neempahla ezilukiweyo. Ilaphu elinolukiweyo libe lelona candelo linokubakho lokukhuphisana nemarike yelaphu ngenxa yeempawu zalo ezifana nezelaphu, iipropati zomzimba ezibalaseleyo, umgangatho ophezulu kunye nexabiso eliphantsi.

Ukusetyenziswa kwelaphu elinoboya obujiyileyo

1. Ukusetyenziswa kwezonyango kweempahla zotyando ezilahlwayo, izigqubuthelo zotyando, amalaphu etafile yokusebenza, ii-apron zotyando, amabala amanxeba, iibhandishi, i-gauze, ii-band-aids, njl.njl.

2. Iindidi zeempahla ezifana nempahla enxibelelanayo, impahla yosana, impahla yoqeqesho, impahla enemibala elahlwayo ebusuku, zonke iintlobo zeempahla zokuzikhusela ezifana neempahla zotyando, njl.

3. Iitawuli zokusula ezifana nezasekhaya, ezomntu, ezobuhle, ezemizi-mveliso, ezomileyo nezasesibhedlele, njl.

4. Ilaphu lokuhombisa elifana nengaphakathi lemoto, ingaphakathi lendlu, ukuhombisa iqonga, njl.njl.

5. Iimveliso zezolimo ezifana negreenhouse yokugcina ubushushu, ukuthintela ukukhula kokhula, ilaphu lokuvuna eliqinileyo, ilaphu elikhusela izinambuzane nelihlala litsha, njl.

6. Ii-nonwovens ezisontiweyo zingasetyenziselwa ukucubungula izinto ezidityanisiweyo ukuvelisa iimveliso ezinesakhiwo "sesandwich" kunye nokuphuhlisa izinto ezintsha ezidityanisiweyo zokusetyenziswa ezahlukeneyo.

Izinto ezingalukwanga ezisontiweyo

Emva kokuba i-polymer ikhutshiwe kwaye yoluliwe ukuze yenze i-filament eqhubekayo, i-filament ifakwa kwi-net, ize emva koko ngokusebenzisa i-bonding yayo, i-thermal bonding, i-chemical bonding okanye i-mechanical reinforcement, i-network ayilukwanga.

Iimpawu: amandla aphezulu, ukumelana okuhle nobushushu obuphezulu (ingasetyenziswa kwiindawo ezingama-150 ℃ ixesha elide), ukumelana nokwaluphala, ukumelana ne-UV, ukwandiswa okuphezulu, ukuzinza okuhle kunye nokuvuleka komoya, ukumelana nokugqwala, ukuthintela isandi, ukuthintela iinundu, ukungangenwa yityhefu. Ukusetyenziswa okuphambili: iimveliso eziphambili ze-spun-bonded nonwovens yi-polypropylene polyester (i-fibre ende, i-staple fiber). Ezona zicelo zixhaphakileyo nezisetyenziswa rhoqo ziingxowa ezingalukwanga, ukupakishwa okungalukwanga njalo njalo, kwaye kulula ukuzibona. kuba indawo yokuqengqeleka kwe-spun-bonded nonwovens yidayimani.

Oku kungasentla kukwazisa umahluko phakathi kwee-nonwovens ezisontiweyo kunye nee-nonwovens ezisontiweyo ezisontiweyo. Ukuba ufuna ukwazi okungakumbi ngee-nonwovens ezisontiweyo, nceda unxibelelane nathi.
