The influence of different fabric materials on the temperature of the bonding surface is as follows: There are several superposition methods and characteristics comparison of woven interlining and fabric. Standard superimposition method: that is, the fabric is on the bottom and the back side is up, and the lining is on the upper bonding side down. The effect of standard stacking and bonding is better, but the effect is lower, and the fabric is easy to stick to dirt.
The coat requires proper elasticity. The shirt collar needs to choose a certain stiffness resin collar lining, mainly for a certain degree of toughness. The minimum stiffness is 5.4cm at a temperature of 135°C. As the temperature increases, the stiffness increases accordingly. .
Bonding time The bonding effect of the interlining and the fabric is greatly affected by time, because the flow of hot melt adhesive into the fabric is related to the peel strength and bonding time for a certain period of time. The bonding of the two layers of fabric is based on the hot melt adhesive connecting the two layers for too short a time. The hot melt adhesive lacks melting and cannot well infiltrate the fabric, so the peel strength is low, but the pressing time is too long and the pressing time is too short. As a result, a large amount of melted glue is soaked into the fabric, and the length of pressing time should be selected according to the density and thickness of the fabric.
Adhesive pressure The pressure and the time of pressure during bonding, and the pressure during bonding are mainly to eliminate the gap between the two layers of fabric, so that the hot melt glue is squeezed into the fabric by external force, and the plate press is added. The pressing form is flat pressure. This pressing method makes the hot melt adhesive start to pressurize from the glass state (solid) until it reaches the viscous flow state. Heating and pressing are synchronized in time. Because the pressing time is longer, the adhesion fastness is higher than that of the roll-belt press, but it is easy to penetrate;
The pressing form of the rolling ironing machine is linear pressing. This pressing method first heats the fabric and the hot melt adhesive at the same time and passes through the oven at the same time. At this time, the unbonded two layers of fabrics are not tightly attached in the heating operation, so that the lining hot melt adhesive cannot be well bonded to the fabric, so the roll-belt pressing machine (except for pre-pressing and pre-heating) It is not as firm as the plate-type pressing, and has a more obvious effect on difficult-to-stick fabrics.
