Kub Melt Web(tseem hu ua kub yaj nplaum nplaum) yog ib qho uas tsis yog -woven, net-zoo li kev sib txuas nruab nrab uas tsim los ntawm siab - nrawm yaj- tshuab ntawm cov thermoplastic polymers. Ob hom tshuaj sib txawv tseem ceeb -Polyamide (PA)thiabPolyester (PES)- ua haujlwm zoo li khoom- lub xeev cov nplaum nplaum uas ua rau muaj kuab lom nyob rau hauv cov txheej txheem thermal tshwj xeeb kom yooj yim rau cov txheej txheem lamination ntawm cov khaubncaws sab nraud povtseg. Tsis zoo li cov kua nplaum nplaum, cov webs no tuav cov qauv porous ncej- khi, kom ntseeg tau tias qhov sib xyaw zaum kawg khaws nws qhov qub huab cua permeability ( ntsuas hauv mm / s) thiab tes-xav.
Chemical Composition thiab Mechanical Properties
Qhov tseem ceeb sib txawv ntawm PA thiab PES nyob rau hauv lawv cov saw molecular, uas dictate lawv polarity thiab adhesion profile rau ntau yam hluavtaws thiab ntuj fibers.
Polyamide (PA):Muab los ntawm nylon resins, PA webs muab cov elasticity zoo dua thiab siab -kev ua tau zoo rau cov khoom ntxeem tau xws li tawv, paj rwb, thiab ntaub nylon.
Polyester (PES):Tsim los ntawm siab - tenacity polyester polymers, PES webs yog tus cwj pwm los ntawm kev thermal stability thiab tshwj xeeb tsis kam rau kev lag luam ntxhua khaub ncaws thiab yellowing.

Kev sib piv: PA vs. PES Specifications
Cov lus hauv qab no muab cov qauv ntsuas uas xav tau rau kev xaiv cov khoom siv hauv cov khau thiab cov khaub ncaws sib dhos:
| Technical Parameter | Polyamide (PA) Kub Melt Web | Polyester (PES) Kub Melt Web |
| Melting Point Range | 95℃- 115 degree | 120℃- 130 degree |
| Qhov hnyav (gsm) | 8g/㎡ – 60g/㎡ | 10g/㎡ – 80g/㎡ |
| Dav Muaj | 1 cm - 300 cm | 1 cm - 280 cm |
| Peel zog (N / 25mm) | 15N-25N (Nylon) | 18N - 30N (ntawm PET) |

Critical Performance Analysis
1. Thermal Activation thiab Melting Points
PAPA Kub Melt WebFeem ntau ua rau qhov kub qis dua (95℃txog 115 degree), ua rau nws nyiam xaiv rau cov cua sov-sensitive substrates xws li nyias TPU films los yog tawv tawv uas muaj feem xyuam rau thermal deformation. PES [Insert Link:PES Kub Melt Mesh] yuav tsum muaj cov khoom siv hluav taws xob ntau dua (120℃txog 130 degree), muab kev nyab xeeb rau cov khoom lag luam raug rau siab - tshav kub tom qab - ua haujlwm lossis ib puag ncig huab cua.
2. Kev ntxhua khaub ncaws thiab ziab ziab tsis kam
PES nthuav tawm cov qauv crystalline ntau dua, uas txhais tau hais tias muaj kev tiv thaiv zoo tshaj plaws tiv thaiv cov tshuaj alkaline thiab siab -kub dej mus txog. Thaum PA tsim nyog rau cov khaub ncaws hnav, PES yog cov qauv kev lag luam rau cov khaub ncaws ua haujlwm thiab cov tsheb sab hauv uas 90℃ntxuav lossis rov ua kom qhuav yog qhov yuav tsum tau ua.
3. Bonding Affinity thiab Substrate Matching
PA Daim Ntawv Thov:Qhov zoo tshaj plaws rau siab -cov ntaub npuag, tawv tawv, thiab nylon-raws li sportswear. Nws lub hauv paus "softness" tiv thaiv qhov chaw laminated los ntawm kev ua nkig.
PES Applications:Qhov zoo tshaj plaws rau siab - polyester meshes density, non-woven composites, thiab hlau-rau-ntaub npuag hauv cov khoom siv hluav taws xob tiv thaiv.
Substrate Compatibility Guide
Xaiv qhov tsis ncaj ncees lawm lub vev xaib tuaj yeem ua rau delamination (peel tsis ua haujlwm) thaum lub sijhawm khoom lag luam.
Nkawm khau (Uppers / Insoles):PA feem ntau yog siv rau nws flex- qaug zog ua haujlwm.
Automotive Sab hauv:PES tau txais kev pom zoo rau nws qhov kev ruaj ntseg UV thiab ua haujlwm rau siab -chav tsev kub (txog 80℃).
Seamless Apparel:PA yog tus qauv rau hems thiab cuffs vim nws qhov qis melting point, uas tiv thaiv "ci marks" ntawm cov ntaub txheej.
FAQ
Q1: Dab tsi yog MOQ rau kev cai gsm lossis dav specifications?
Rau tus qauv PA/PES webs (10g-30g), MOQ feem ntau yog 1,000 meters ib yob. Rau cov kev cai tshwj xeeb uas suav nrog cov yaj tshwj xeeb-flow Performance index (MFI) resins lossis tsis yog qauv dav tshaj 200cm, MOQ yog 5,000 square meters.
Q2: Kuv yuav ua li cas txheeb xyuas kev ua raws li Oeko-Tex Standard 100 rau kev xa tawm?
Txhua qhov khoom xa tuaj los ntawm WithTech yog nrog los ntawm ib pawg -COA tshwj xeeb (Certificate of Analysis). Peb cov PA thiab PES resins raug kuaj rau cov hlau lead, phthalates, thiab formaldehyde kom ua tau raws li REACH thiab Oeko-Tex Class I (muaj kev nyab xeeb rau menyuam mos).
Q3: Cov webs no puas tuaj yeem siv rau kev sib txuas cov hlau foils rau cov ntaub?
Yog lawm. PES Kub Melt Mesh yog tshwj xeeb tshaj yog zoo rau kev sib txuas ntawm txhuas los yog tooj liab foils rau polyester substrates. Peb pom zoo kom kub - nias siab ntawm 3-4 kg / cm² rau yam tsawg kawg nkaus ntawm 12 vib nas this los xyuas kom meej molecular diffusion thoob plaws lub interface.
