Kev cai kub yaj xov pajengineering yog qhov tseeb configuration ntawm thermoplastic co-polyamide (PA) los yog co-polyester (PES) filaments kom tau raws li cov neeg kho tshuab thiab thermal ciam teb. Cov tshuaj formulation tso cai rau kev hloov pauv ntawm cov polymer lub crystalline qauv, hloov lub melting point nyob rau hauv lub caij nyoog thermal qhov rais ntawm 85℃mus rau 150℃(± 3℃kam rau ua). Ib txhij, linear ceev configuration thoob plaws ntau yam ntawm 20D rau 1200D dictates qhov kawg hnyav (gsm),tensile zog, thiab flexural modulus ntawm cov ntaub sib xyaw. Los ntawm kev hloov kho cov khoom siv tsis zoo no, cov kws tsim qauv ua kom cov qauv kev sib raug zoo nrog kev ua haujlwm ncaj nraim -knitting, ncig-knitting, los yog nqaim-cov tshuab xaws, tsim siab - kev ua haujlwm cuam tshuam uas ua tiav lub zog tev ntau dua 50 N / cm thaum lub sij hawm qis qiskub-nias kev sib txuaslub voj voog.
1. Linear Density and Cross -Sectional Geometry (Denier Customization)
Hloov cov denier (D) thiab filament suav (F) ncaj qha modulates saum npoo - rau - huab hwm coj piv thiab capillary flow mechanics ntawm molten polymer. High-Filament configurations (piv txwv li, 150D/48F) nce qhov chaw tiv tauj, uas optimizes wetting kinetics thoob porous substrates thaum lub sij hawm thermal activation. Conversely, low-filament specs (piv txwv li, 50D/12F) txwv tsis pub cov nplaum ntws mus rau thaj chaw hauv cheeb tsam, khaws cia cov macro-porosity thiab qub huab cua permeability ntawm cov qauv textile.

Cov ntaub ntawv Table: Engineering Specifications rau Custom Polymer Matrix Variants
Cov matrix hauv qab no txhais cov kev hloov kho lub cev tsis muaj peev xwm muaj rau siab -Volume Tier-1 manufacturing optimization:
| Polymer Base | Denier Options (D) | Filament Array (F) | Melting Point Range | Lub Hom Phiaj Melt Flow Index (MFI) | Application Alignment |
| Co-Polyamide (PA) | 20D – 300D | 3F – 72F | 85℃- 115 degree | 15 - 25 g / 10 feeb (150 degree) | Tawv, TPU Web, Seamless Apparel |
| Co-Polyester (PES) | 30D – 1200D | 10F – 288F | 110℃- 150 degree | 25 - 45 g / 10 feeb (150 degree) | 3D Fly-Knit Uppers, Automotive Linings |
| Recycled PES (GRS) | 50D – 600D | 12F – 144F | 110℃- 130 degree | 20 - 35 g / 10 feeb (150 degree) | Eco-Ua raws li Cov Khau Taw, Sustainable Trim |
2. Spectral Consistency ntawm Dope Dyeing (Color Matching)
Txhawm rau tiv thaiv cov xim los ntshav los yog qhov sib txawv tsis sib xws ntawm cov kab sib txuas, cov xov paj tshwj xeeb yuav tsum tau dope-dyeing es tsis yog pob -dyeing. Masterbatch pigments yog qhia ncaj qha rau hauv lub polymer yaj ua ntej extrusion spinneret. Cov xim sab hauv no ua kom cov xov paj tuav cov xim nrawm rau kev txhuam thiab lub teeb ntawm Qib 4.5+ ntawm cov nplai grey. Kev txheeb xyuas spectral yog ua los ntawm kev siv spectrophotometers los lav qhov sib txawv ntawm Delta E ntawm tsawg dua 0.8 hla siab - ntim ntau lawm.
3. Co-Polymer Modification Flow (Melting Point Customization)
Hloov cov thermal ua tau zoo ntawm qis- melting- taw tes filaments yuav tsum tau hloov kho stoichiometric ntawm cov monomers thaum lub sij hawm polymerization.
Chain Disruption:Qhia txog cov tshuaj lom neeg tshwj xeeb lossis cov saw hlau sab cuam tshuam cuam tshuam cov ntim ntim ntawm cov crystalline domains, xa me nyuam rov ua kom kub rau qhov ruaj khov 85℃hauv paus rau cov cua sov-rhiab qaum lossis tawv tawv.
Thermal Window Matching:Rau kev lag luam lim lossis siab -kub ua haujlwm, ua kom cov crystalline segment ratios hloov qhov ua kom siab tshaj plaws rau 130℃-150 degree, kom ntseeg tau tias cov filament tseem ruaj khov thaum lub sij hawm tom qab sublimation luam ntawv lossis vulcanization theem.
4. Yam tsawg kawg nkaus Order Quantity (MOQ) thiab Sourcing Parameters
Cov kev hloov kho kev lag luam yuav tsum muaj qhov tsawg kawg nkaus qhov pib ua kom ruaj khov ntawm cov yaj-spinning manifolds thiab tswj kom tsis txhob muaj qhov nro extrusion. Rau cov qauv nyoos dawb configurations nrog ua ntej - kuaj denier indices, batch processing txwv yog optimized rau ceev ceev, whereas kev cai xim masterbatch kev koom ua ke yuav tsum tau ntau dua khiav ntev kom tshem tawm polymer cross- paug nyob rau hauv lub extrusion kab.
