Mhepo inopisa isina mucheka
Mhepo inopisa isina kuruka jira ndeyemhando yemhepo inopisa yakasungirirwa (inopisa-inokungurutswa, mhepo inopisa) jira risiri rakarukwa. Mhepo inopisa isina kuruka jira inogadzirwa nekushandisa mhepo inopisa kubva mumudziyo wekuomesera kuti ipinde mukati medandemutande refiber mushure mekunge mafiber akakandwa, zvichiita kuti apiswe uye abatanidzwe pamwechete.
Mhepo inopisa yekubatanidza maitiro
Mhepo inopisa inoreva nzira yekugadzira yekushandisa mhepo inopisa kupinda mukati me fiber mesh pamidziyo yekuomesa uye kuinyungudutsa pasi pekupisa kuti ibudise chisungo. Nzira dzekupisa dzinoshandiswa dzakasiyana, uye maitiro uye maitiro ezvigadzirwa zvinogadzirwa zvinosiyanawo. Kazhinji, zvigadzirwa zvinogadzirwa nemhepo inopisa zvine hunhu hwakadai se fluffiness, kupfava, kunaka kwakanaka, uye kuchengetedzwa kwakasimba kwekudziya, asi simba radzo rakaderera uye rinowanzo shanduka.
Mukugadzirwa kwemhepo inopisa, imwe chikamu cheyakaderera melting point bonding fibers kana maviri-component fibers inowanzosanganiswa mufiber web, kana chigadziro chekuparadzira hupfu chinoshandiswa kuisa imwe chiyero chehupfu hwehupfu kune fiber web isati yapinda muimba yekuomesa. Iko kunyunguduka kwehupfu yakaderera pane iyo yefiber, uye inokurumidza kunyunguduka kana ichipisa, zvichiita kuti ibatane pakati pemafiber.
Tembiricha yekudziya yemhepo inopisa yekubatanidza kazhinji yakadzikira pane inonyungudika yefiber huru. Nokudaro, pakusarudzwa kwefibers, kufananidzwa kwezvinhu zvinopisa pakati pefiber huru uye fibre yekubatanidza kunofanira kufungwa, uye musiyano pakati pekunyunguduka kwechisungo chebhanhire uye nzvimbo yekunyunguduka yefiber huru inofanira kukwidziridzwa kuitira kuderedza kupisa kwekushisa kwefiber huru uye kuchengetedza zvinhu zvayo zvepakutanga.
Simba rekubatanidza fiber rakaderera pane iro remafibhi akajairwa, saka mari yakawedzerwa haifanirwe kunge yakakura, kazhinji inodzorwa pakati pe15% ne50%. Nekuda kwekudzikira kwayo kwekudziya kwekudzikira, maviri-chikamu faibha akanyatsokodzera kushandiswa ega kana semafiibhi ekubatanidza mukugadzirwa kwemhepo inopisa yakasungirirwa machira asina kuruka, achigadzira anobudirira poindi bonding zvimiro. Zvigadzirwa zvinogadzirwa nenzira iyi zvine simba rakakura uye ruoko rwakapfava runonzwa.
Kushandiswa kwemhepo inopisa isina kuruka jira
Fiber webs inoumbwa ne thermoplastic synthetic fibers inogona kusimbiswa nekupisa kusungirirwa, zvakadai sepolyester, naironi, polypropylene, nezvimwewo zvinowanzoshandiswa mukugadzirwa kwemachira asina kurukwa. Nekuda kwekushaikwa kweiyo thermoplasticity yemafibers akadai sedonje, makushe, hemp, uye viscose, iyo fiber network inoumbwa chete neaya mafiber haigone kusimbiswa nekupisa kwekubatana. Nekudaro, hushoma hwefiber dzakadai sedonje nemvere dzemakwai zvinogona kuwedzerwa kune thermoplastic faibha webs kuvandudza zvimwe zvimiro zvemachira asiri akarukwa, asi kazhinji haafanire kudarika 50%. Semuenzaniso, jira rinopisa rakaputirwa rakasungirirwa risiri rakarukwa rakagadzirwa nekotoni / polyester muyero ye30/70 yekusanganiswa inogona kuvandudza zvakanyanya kunyura kwemwando, kunzwa kwemaoko, uye kupfava, zvichiita kuti ive yakakodzera kwazvo kushandiswa mune zvekurapa uye zvehutano zvigadzirwa. Sezvo iyo yekotoni fiber yemukati inowedzera, kusimba kwemachira asina kurukwa kunoderera. Ehe, kune fiber webs inoumbwa zvachose neasiri thermoplastic fibers, zvinokwanisika kufunga nezve kushandisa hupfu hwekuparadzira uye inopisa nzira dzekubatanidza yekusimbisa.
Kupisa kwakaputirwa jira risiri rakarukwa
Hot rolling process uye kupisa kwemhepo maitiro ese akakosha ekugadzira maitiro. Iyo inopisa yekukungurusa nzira inosanganisira kudziyisa jira risiri rakarukwa zvishandiswa patembiricha yepamusoro uye wobva wazvitsikirira muhumwe hukobvu hwejira risiri rakarukwa kuburikidza nekukunguruka. Hot bonded nonwoven machira anogona kuwanikwa kuburikidza dzakasiyana kudziyisa nzira. Iyo yekubatanidza nzira uye maitiro, fiber mhando uye combing process, uye webhu chimiro zvinozopedzisira zvakanganisa mashandiro uye kutaridzika kwemachira asina kuruka.
Hot rolling adhesive nzira
Kune fiber webs ine yakaderera melting point fiber kana maviri-component fibers, inopisa rolling bonding kana inopisa air bonding inogona kushandiswa. Kune akajairwa thermoplastic fibers uye faibha webs yakasanganiswa neasiri thermoplastic fibers, inopisa rolling bonding inogona kushandiswa.
Hot rolling bonding nzira inowanzokodzera zvigadzirwa zvitete zvine huremu hwedandemutande hwe20-200g/m, uye huremu hwewebhu hwakanyanya huri pakati pe20-80g/m. Kana dandemutande rakanyanya kukora, kubatana kwechikamu chepakati hakuna kunaka, uye delamination inowanzoitika.
Kubatana kwemhepo kunopisa kwakakodzera kune zvigadzirwa zvine huwandu hwehuwandu hwe16 ~ 2500g / m. Mumakore achangopfuura, kugadzirwa kwemhepo yakatetepa inopisa yakasungirirwa machira asina kuruka kwave nekukurumidza, nehuwandu hwehuwandu hunowanzo pakati pe16-100g/m.
Pamusoro pezvo, kusungirirwa kwemafuta kunowanzoshandiswa mukugadzira machira asina kuruka (akadai se.nyungudusa machira elaminated nonwoven), kana senzira yekuwedzera kune dzimwe nzira dzekusimbisa. Semuyenzaniso, kusanganisa hushoma hwemafibisi akadzikira mufiber web, kusimbisa nekubaya tsono, uyezve kubatana nemhepo inopisa kunogona kuvandudza zvakanyanya kusimba uye kugadzikana kwedimensional yezvigadzirwa zvakabayiwa netsono.
Kushandiswa kwejira rinopisa-rakakungurutswa risiri rakarukwa
Zvigadzirwa zvemhepo zvinopisa zvine hunhu hwepamusoro fluffiness, elasticity yakanaka, ruoko rwakapfava kunzwa, kudziya kwakasimba kuchengetedza, kufema kwakanaka uye kupindirana, asi simba ravo rakaderera uye rinowanzoita deformation. Nekuvandudzwa kwemusika, mhepo inopisa inosungirirwa zvigadzirwa zvinoshandiswa zvakanyanya mukugadzira zvigadzirwa zvinoraswa nemaitiro avo akasiyana, senge machira evana, mapedhi evakuru ekusagadzikana, machira ezvigadzirwa zvehutsanana hwevakadzi, napkins, matauro ekugezera, machira etafura anoraswa, nezvimwe; Zvigadzirwa zvakakobvu zvinoshandiswa kugadzira zvipfeko zvinodzivirira kutonhora, mubhedha, mabhegi ekurara emwana, matiresi, macushion emasofa, nezvimwe. High density inopisa inonyunguduka inonyungudutsa zvigadzirwa zvinogona kushandiswa kugadzira sefa zvinhu, zvigadziriso zvinonzwika, zvinhu zvekuvhundutsa, nezvimwe.
Dongguan Liansheng Non woven Technology Co., Ltd.yakavambwa muna Chivabvu 2020. Ibhizimusi rekugadzira jira rakakura risingarukwe rinobatanidza tsvakiridzo nekusimudzira, kugadzira, uye kutengesa. Inogona kuburitsa mavara akasiyana-siyana ePP spunbond machira asiri akarukwa ane hupamhi husingasviki 3.2 metres kubva pa9 gramu kusvika 300 magiramu.
