Transparent TPU hot melt yarn is a high-molecular-weight Thermoplastic Polyurethane filament engineered with a completely amorphous structural morphology to ensure optimal light transmission (>92%) ntawm kev sib txuas lus. Tsis zoo li opaque lossis semi-pub Polyamide lossis Polyester lwm txoj hauv kev, qhov tshwj xeeb filament hloov mus rau hauv ib txheej ntshiab, isotropic nplaum txheej thaum raug rau qhov kub thiab txias ntawm 110℃thiab 130℃. Nyob rau hauv siab - kev ua tau zoo khau siab, seamless apparel, thiab laminates technical laminates, pob tshab TPU yarn tshem tawm cov tsom iav qhov muag thiab cov seem dawb uas muaj nyob rau hauv cov tsoos kub- xovxwm cov txheej txheem. Qhov no tsim ib daim ntawv cog lus tsis pom tseeb uas khaws cov ntaub ntawv hauv cov xim tiag tiag thaum tuav lub zog zoo sib xws ntawm ntau dua 45 N / cm.
1. Ua kom pom kev ruaj khov thiab zoo tshaj qhov pom kev zoo nkauj
Cov txheej txheem thermal bonding fibers tawg qhov teeb meem tshwm sim vim lawv ib nrab -crystalline zones, tsim cov kab dawb hauv zos los yog cov dej khov uas ua rau cov ntaub tsaus nti lossis cov ntaub ntawv translucent. Transparent TPU yarn daws qhov kho qhov muag degradation los ntawm kev tswj cov monomer piv txwv thaum lub sijhawm sib txuas, uas inhibits micro-crystalline tsim.
Thaum sib xyaw ua ke los ntawm kev siv lub tiaj tiaj-knitting lossis paj ntaub, cov ntaub ntawv melts tag nrho rau hauv lub substrate yam tsis tau hloov qhov kev ntxhib los mos los yog ntxiv ntau. Qhov no tso cai rau kom huv si, nyoos-ntug tiav thiab ultra- nyias cov ntaub hauv cov khaub ncaws niaj hnub, tswj cov ntaub qub drape thiab txhais tes.
Thov ib qho kev TDS thiab cov qauv piv txwv ntawm peb cov ultra- ntshiab TPU filaments los kuaj hla -sectional clarity ntawm koj cov kab ntau lawm.

2. Quantitative Performance: Xim ceev thiab Polymer Metrics
Siv cov xov paj pob tshab TPU kom ntseeg tau tias cov qauv seams tsis daj lossis tsis xim raws li UV raug lossis siab - ua haujlwm kub.
Cov ntaub ntawv: Pob tshab TPU Filament vs. Opaque Polymers
Cov ntaub ntawv dawb hauv qab no sib piv cov khoom siv kho qhov muag thiab cov khoom siv kho qhov muag kom ua tiav qhov pom kev zoo nkauj yam tsis muaj kev cuam tshuam kev ncaj ncees:

3. Advanced Decorative Sewing thiab kev sib xyaw ua ke
Kev koom ua ke pob tshab TPU yarn rau hauv cov khoom siv xaws zoo nkauj tso cai rau cov tuam txhab hloov cov kua PU cov nplaum thiab cov kab xev nrog cov txheej txheem huv, qhuav.
- Txhim Kho Paj Ntaub: Khiav qhov ntshiab TPU fiber ntau nyob rau thaj tsam ntawm cov paj ntaub intricate locks xoob xov xaus thaum lub sij hawm chav teeb, tiv thaiv fraying nrog xoom adhesive nyem- tawm.
- Invisible Selvedge Hems: Hauv cov ntaub curtains los yog cov khaub ncaws hnav, siv 75D ntshiab TPU filament nyob rau hauv ntug-weave qauv tso cai rau huv si, stitchless hems uas tuaj yeem tuav rov qab siv lub tshuab ntxhua khaub ncaws yam tsis tau tev.
- Multi-Layer Fabric Fusion: Thaum siv ib sab los yog lwm txoj hauv kev rau cov nplaum [Ntxig Txuas: TPU Web, Co-PA Web, los yog cov ntawv sib txuas sib txuas zoo sib xws], nws muab kev txhawb nqa hauv cheeb tsam hauv cheeb tsam tsom, khaws cia qhov chaw cua ntawm cov khoom siv hluav taws xob.
4. Daim Ntawv Thov Kev Lag Luam: Engineering Fly-Knit Footwear Uppers
Hauv kev tshawb xyuas ntau lawm tsis ntev los no rau Tier-1 hom khau kis las kis las, hloov tus qauv qis-melt polyester nrog WithTech 150D pob tshab TPU yarn nyob rau hauv ib lub jacquard dub knit sab sauv kho ib qho chaw ua haujlwm tsis xws luag. Cov yav dhau los polyester fiber sab laug faint dawb streaks raws lub eyelet thaj ua rau thaj tom qab 125℃kub-nias voj voog.
Kev hloov kho rau peb qhov kho qhov muag - qib pob tshab TPU filament tshem tawm qhov pom kev tsis pom kev tag nrho, txo lub Hoobkas tsis lees txais tus nqi los ntawm 4.2% mus rau tsawg dua 0.1%. Tsis tas li ntawd, qhov kev hloov pauv tau nce dynamic flex endurance mus rau ntau tshaj 100,000 lub voj voog, ua tau raws li cov qauv kev ua tau zoo thoob ntiaj teb.
Technical Standards thiab Environmental Compliance

Rau cov saw hlau ua haujlwm rau lub hom phiaj ncig, peb muab cov kev hloov pauv ruaj khov uas sib piv cov khoom siv kho qhov muag tiag tiag siv GRS cov ntawv pov thawj -kev lag luam rov siv dua polyurethane inputs, txhawb nqa los ntawm Daim Ntawv Pov Thawj Ua Haujlwm (TC) tag nrho.
FAQ
Q1: Dab tsi yog MOQ rau koj pob tshab TPU kub yaj xov paj hauv cov qauv tsis pom zoo?
Peb lub Hoobkas MOQ rau pob tshab TPU yarn nyob rau hauv tus qauv configurations, xws li 75D / 24F thiab 150D / 36F, yog 100kg. Rau kev cai linear densities los yog ntau yam -filament arrays, qhov tsawg kawg nkaus extrusion kab yuav tsum tau yog 500kg ib batch.
Q2: Puas yog koj cov xov paj TPU pob tshab tig daj thaum raug rau siab -cov txheej txheem kub vulcanization?
Tsis yog. Peb cov ntshiab TPU polymer matrix siv aliphatic los yog tshwj xeeb los tiv thaiv - daj uas muaj ntxhiab isocyanate qauv. Nws khaws nws Qib 4.5 UV tsis kam thiab cov khoom siv kho qhov muag pom tseeb txawm tias lub sijhawm txuas ntxiv vulcanization lossis cua sov- teeb tsa mus txog 135℃.
Q3: Cov xov paj pob tshab TPU puas tuaj yeem ua tiav siv cov txheej txheem ncig lossis tiaj tus- cov khoom siv knitting?
Yog lawm. WithTech siv lub tswv yim qis - kev sib txhuam silicone ua tiav rau lub ntsej muag filament. Qhov kev hloov kho no tiv thaiv kev txhim kho zoo li qub thiab ua kom zoo, tso cai rau cov xov paj kom zoo los ntawm cov qauv kev lag luam knitting feeders ntawm nrawm txog 1.2 m / s yam tsis muaj kev tawg.
