I. Inkqubo yeLaphu eliNgelukiweyo le-Elastic Spunlace Nonwoven

Eyona nto iphambili kwilaphu le-spunlace nonwoven elastiki ikukufezekisa ukuhambelana "kwesakhiwo se-elasticity + spunlace" ngokukhetha izinto eziluhlaza kunye nokwenza ngcono inkqubo. I-Changshu Yongdeli Spunlaced Nonwoven Fabrics Co., Ltd. iqinisekisa ukuthamba okuzinzileyo kunye nokusebenza okuthembekileyo ngokulawula inkqubo ngononophelo. Inkqubo ethile yile ilandelayo:

Ukukhethwa kwezinto ezisisiseko kunye nomlinganiselo: Khetha iifayibha ze-polyester ezithambileyo ezikumgangatho ophezulu. Iifayibha ze-polyester ezithambileyo zisebenzisa iintlobo eziguquliweyo ezinezinga eliphezulu lokubuyisela i-elastic (izinga lokubuyisela i-elastic ≥ 90%), ezinokubuyela umva ngokukhawuleza emva kokuzolula;

Ukuvula nokuxuba: Sebenzisa isixhobo sokuvula nokuxuba esikhethekileyo ukusasaza iifayibha ze-polyester elastiki. Esi sixhobo sisebenzisa uyilo oluphantsi loxinzelelo ukuze siphephe ukuba iifayibha ze-elastic zilahlekelwe bubuthambile bazo ngenxa yokuzolula kakhulu; emva koko singena kumatshini wokuxuba we-biaxial, apho iiseti ezininzi zamazinyo okuxuba zifikelela ekuxubeni iifayibha ezifanayo ukuqinisekisa ukusasazwa okufanayo kweefayibha ze-elastic kwi-mesh yelaphu, kuthintelwe ukungalingani kobuthambile kwiindawo ezithile, kubeka isiseko sokwakheka kwewebhu okulandelayo kunye nokubumba i-elastic.

Ukudibanisa kunye nokwakheka kwewebhu (ulawulo lokujonga i-elastic): Iifayibha ze-elastic zingena kumatshini wokuxubha ifayibha ye-elastic ochanekileyo kakhulu. Umatshini wokuxubha usebenzisa ilaphu lenaliti ekhethekileyo (ilaphu lenaliti elinomonakalo omncinci) kunye neerola ezihlengahlengiswayo ukwahlula iifayibha ngelixa ulawula ulwalathiso lolungiselelo lwefayibha (ngokuyintloko ukuqina kwe-longitudinal, kunye nokuqina kwe-lateral njengesongezelelo), ukuhambelana neemfuno ze-elastic ze-patches zonyango (ezifana nokuziqhelanisa ne-longitudinal ukuya kwicala lokushukuma kwamalungu). Ngexesha lenkqubo yokuxubha, ukujonga ngexesha langempela ukuphambuka kobukhulu (kulawulwa ngaphakathi kwe-±2%) kuqinisekisa ukufana kwe-mesh yelaphu, kuthintelwe ukutyeba okungalinganiyo okuchaphazela iziphumo zokugquma kunye nokunamathela okulandelayo.

Ukuqinisa i-spunlace ethambileyo (inkqubo ephambili): Eli linyathelo elibalulekileyo lokunika imveliso ukuqina, kusetyenziswa inkqubo ethi "multiple progressive pressure spunlace":

I-spunlace yokuqala enoxinzelelo oluphantsi (uxinzelelo lwe-5-8 MPa): Qala ulungise isakhiwo selaphu ukuze uthintele ukufuduka kwefayibha okugqithisileyo okubangelwa yi-spunlace enoxinzelelo oluphezulu, ukhusele isakhiwo se-elastic seefayibha ze-polyester elastiki;

I-spunlace ebhekisa kwicala eliphakathi loxinzelelo (uxinzelelo lwe-10-12 MPa): Ngentloko ye-spunlace etyebileyo (kwi-engile ye-30°-45° ukuya kwi-mesh yelaphu) ukuze kutshizwe ngendlela ebhekisa kwicala, okwenza iifayibha ze-elastic zenze isakhiwo "se-tangle-elastic reserve" kwicala elimiselweyo (elide), enika indawo yokulula nokubuyela umva;

I-spunlace yokubumba uxinzelelo oluphezulu (uxinzelelo lwe-13-15 MPa): Sebenzisa intloko ye-spunlace enobunzima obuphezulu ukuqinisa ngokupheleleyo i-mesh yelaphu, ukuqinisekisa ukuxinana okuqinileyo kwee-elastic fibers nezinye ii-fibers, ngelixa ulawula ngokuchanekileyo uxinzelelo ukuze uphephe ukutyunyuzwa kwee-fibers, ekugqibeleni wenze isakhiwo esizinzileyo "see-elastic fibers njengesakhelo, i-spunlace entanglement njengenkxaso", kunye nesantya sokwelula eside ukuya kuthi ga kwi-15%-30% kunye nesantya sokwelula ecaleni ukuya kuthi ga kwi-8%-15%, ukuhlangabezana neemfuno zee-patches zonyango zokunamathela kwemilenze.

Ukuphelelwa ngamanzi emzimbeni kunye nokubumba ngobushushu obuphantsi: Ilaphu elimanzi nelingenalukiweyo emva kokuqinisa i-spunlace lingena kwisixhobo sokukhupha amanzi emzimbeni nge-vacuum (izinga lokuphelelwa ngamanzi emzimbeni yi-70%-80%), emva koko lingena kwisixhobo sokomisa umoya oshushu esiphantsi (ubushushu yi-70-90°C), kunye nobushushu obuphantsi kunobushushu bokomisa ilaphu eliqhelekileyo le-spunlace nonwoven (100-120°C), elinokuthintela iifayibha ze-polyester ezithambileyo ukuba zingaphulukani nokuqina ngenxa yobushushu obuphezulu. Ngexesha lenkqubo yokomisa, ukubumba nge-elastic kwenziwa ngaxeshanye. Uxinzelelo lomphezulu welaphu lulawulwa zii-roller zokulawula ubushushu ukuqinisekisa ukuba imveliso igcina ukusebenza okuzinzileyo kokubuyisela i-elastic emva kokomisa, kunye nomthamo womswakama olawulwa ngaphakathi kwe-5%.

Unyango lwangaphambi komphezulu (ukufanisa uboya): Kwiimfuno ezilandelayo zoboya, iimveliso ezomisiweyo zinyangwa kwangaphambili komphezulu: kusetyenziswa iteknoloji yonyango lomphezulu weplasma ukuphucula amandla omphezulu (uxinzelelo lomphezulu ≥ 38 mN/m), ukuphucula ukunamathela kwi-glues ezishushu ezinyibilikayo, ii-gel ze-silicone, kunye nezinye izinto zoboya, kunye nokuphepha iingxaki "zokususa iglu"; ​​kwangaxeshanye, unyango oluthambileyo lwenziwa, ngokucinezela kancinci umphezulu welaphu ngee-roller ezithambileyo zoxinzelelo, ukuqinisekisa ukuba umphezulu welaphu uthambile (ukuphambuka koboya ≤ 0.1 mm/m), ukubonelela ngesiseko soboya obufanayo.

Ukusika kunye nokuhlolwa komgangatho: Ngokweemfuno zobubanzi bomqukumbelo wabathengi beepatch zokuncamathelisa zonyango (ububanzi obuqhelekileyo yi-0.5 - 2 m), iimveliso zinqunyulwa ngoomatshini bokusika abachanekileyo. Inkqubo yokusika isebenzisa ulawulo oluvaliweyo lwe-tension ukuze kuthintelwe ukuguquguquka kwe-elastic kweemveliso ngenxa yokwelula; kwinkqubo yokuhlolwa komgangatho, ukongeza kwiimvavanyo zenkangeleko eqhelekileyo kunye namandla, "uvavanyo lokusebenza lwe-elastic" (ukuvavanya izinga lobude kunye nezinga lokubuyisela i-elastic ngomatshini wokuvavanya ukuxinana) kunye "novavanyo lokuhambelana nokugquma" (ukulinganisa ukugquma emva kokuvavanya ukunamathela komaleko wokuncamathelisa) kongezwa ukuqinisekisa ukuba iqela ngalinye leemveliso lihlangabezana nemigangatho ye-substrates zepatch zokuncamathelisa zonyango.
