paste dotinterlining:There are three main process parameters - temperature,pressure, time. It mainly depends on the typeof lining and performance on the hot melt adhesive, fabric andbonding equipment. Reference parameters provided by thelining manufacturer. Garment factories should be chosen accordinglyfor bonding fabrics and interlining trial, from which to select thebest bonding process.
1, temperature: lining fabric and glue, bonding temperature andbonding time and stress-related, time and pressure must, if thetemperature is too low then the lack of adhesion, peel strength,and washing was reduced; If the temperature is too high then thefabric is easy yellow, peel strength will be reduced. Therefore, the bonding temperature shouldbe based on the thermal properties of adhesives and fabrics todecide.
2, pressure: pressure has three role.
a/ close to the lining and fabric, easy to heatconduction.
b/ the shear stress given tomelt, so that lower melt viscosity of hot melt adhesive, hot meltadhesive to facilitate the flow ofinfiltration.
c/ reduce the gap between the hot meltadhesive and fabric, easy to melt embedded within the fabric, butalso easy to melt and the fibers of molecular chains of mutualdiffusion of molecular chains can improve the bondingstrength.
Bondingpressure determines the size of the heat flow properties in themelt. Pressure is toosmall to affect the peel strength; excessive pressure will not onlyresult in the phenomenon of infiltration material, but will affectthe fabric feel, fabric surface caused by the aurora.Fusible interlining cloth Pressing pressure range:
Shirt Interlining (PEplastic) 2 ~ 3gkf/cm2
Coat interlining (PA, PET plastic) 0.3 ~0.5kgf/cm2
FurInterlining (PA, EVA glue) 0.2 ~ 0.3kgf/cm2
3, bonding time
Bonding process can bedivided into three stages, each stage is the heating time requiredfor the time t1, the actual bonding time and fixation time t2t3. Fixation is due later in the removal of pressure, sooften seen as a bonding time t1 and t2 and: t = t1 t2.
Heating time t1 and the fabric thickness and thermal conductivity,but also with the way the heat transfer bonders. Garment factoriesin the adhesive, before testing the heating time of the selectedfabric t1, t2 actual time depends on the hot melt adhesiveinfiltration time and the diffusion rate, and then bonding time canbe accurately determined.
Hot melt adhesive can be extended to fully infiltrate the fabric oftime and spread to infiltrate the internal fabric is conducive tothe improvement of peel strength. But for too long will produceadhesive infiltration material (a plastic) phenomenon. Fusibleinterlining cloth bonding time range:
Shirt Interlining (PEplastic) 15 ~ 15s
Coat interlining (PA, PET plastic) 12 ~20s
FurInterlining (PA, EVA glue) 10 ~ 15s
