Seamless underwear ntau lawmsiv lub voj voog knitting lossis ultrasonic bonding thev naus laus zis los tshem tawm cov tsoos stitched seams, yuav tsum muaj siab - cov ntaub ntawv thermoplastic precision los xyuas kom muaj kev ncaj ncees. Qhov kev sib tw tseem ceeb yog kev tswj hwm ntawmtensile zogthiab elastic rov qab ntawm cov khaub ncaws ntug. Txhawm rau ua tiav 0.1mm - 0.3mm ultra-thin tiav yam tsis muaj ntug curling, cov tuam txhab yuav tsum koom ua keTsawg Melting Point Xov Paj(feem ntau Polyamide-raws li) lossis tshwj xeebBonding xov that activates at 85°C to 110°C. These materials provide a localized thermal fuse that stabilizes raw-cut edges while maintaining a soft hand-feel and compliant elongation (>200%) xav tau rau cov khaub ncaws intimate.
1. Tshem tawm Ntug Curling hauv Raw- Txiav Fabrics
Ntug curling tshwm sim vim qhov tsis sib haum nrog kev ntxhov siab ntawm lub ntsej muag thiab nraub qaum yarns hauv ib zaug -jersey ncig knits. Cov pa txhua yam hemming nce thickness (gsm), uas cuam tshuam qhov "invisible" profile ntawm seamless garments.
Kev daws teeb meem:Txuas 20D / 3F lossis 30D / 10FKhaub ncawsKub Melt Polyamide filaments rau hauv ntug-feed system. Thaum lub sij hawmkub-nias kev sib txuastheem (115℃rau 12-15 vib nas this), cov xov paj melts thiab encapsulates thawj nylon / spandex fibers, tsim ib tug stabilized ntug nrog ib tug tev lub zog ntawm ntau tshaj los yog sib npaug zos rau 15 N / cm.
2. Sib npaug Bonding Strength nrog daim tawv nqaij - Hu rau kev nplij siab
High -cov nplaum nplaum feem ntau ua rau muaj zog Shore hardness, ua rau tawv nqaij khaus thiab txo qis breathability. Rau cov khaub ncaws zoo sib xws, qhov nruab nrab ntawm kev sib txuas yuav tsum muaj qhov qis qis ntawm elasticity.
Kev tsim khoom ncaj qha rau Oeko-Tex Class I tau lees paub cov xov sib txuas.

3. Precision Thermal Setting thiab Dimensional Stability
Inconsistent heat distribution during the setting process leads to size variance and "ghosting" marks. Seamless garments require a narrow thermal window; if the temperature exceeds the target by >10 degree, spandex core tuaj yeem raug thermal degradation, txo cov tsoos tsho elastic rov qab los ntawm 20-30%.
Kev daws teeb meem:Siv WithTechTsawg Melting Point Xov Pajnrog rau qhov nqaim melting ntau (± 3℃kam rau ua). Calibrate muaj cua kub presses rau 120℃nrog ib tug nip siab ntawm 3.5 bar. Qhov no ua kom ntseeg tau tias [Insert Link:Khaub ncaws] cov ntaub ntawv ntws txaus rau daim ntawv cog lus tab sis tsis nkag mus rau sab nrauv ntawm daim ntaub.
FAQ
Q1: Dab tsi yog MOQ rau 20D Polyamide Tsawg Melting Point Xov Paj hauv Raw Dawb?
Peb tus qauv MOQ rau 20D / 3F thiab 30D / 10F PA Kub Melt Yarn yog 50kg. Rau dope-dyed variants kom phim lub caij nyoog pantone xim, MOQ yog 500kg ib xim kom paub meej batch-rau-batch ΔE <0.5.
Q2: Cov ntaub ntawv sib txuas no puas muaj kev nyab xeeb rau menyuam mos- qib seamless khaub ncaws?
Yog lawm. Tag nrho WithTechBonding xovthiab TPU webs yogOeko-Tex Standard 100Chav kawm kuv tau ntawv pov thawj. Lawv tsis muaj phthalates, formaldehyde, thiab cov hlau hnyav, ua tau raws li cov cai nruj tshaj plaws rau kev sib cuag ntawm daim tawv nqaij.
Q3: Kuv yuav ua li cas tiv thaiv yellowing ntawm cov kab sib txuas hauv cov ntaub dawb?
Peb muab "Anti-Yllowing" qib PES thiab PA filaments nrog Phenolic Yellowing tsis kam ntsuas qhov siab dua lossis sib npaug rau 4 (ISO 105-X18). Xyuas kom lub kub xovxwm kub tsis tshaj 135℃los tiv thaiv polymer oxidation.
