How to bond the Interlinings? The influence of different fabric materials on the bonding surface temperature is as follows: Several stacking methods and characteristics comparison between spun interlining and fabric. Standard stacking method: the fabric is in the bottom and the reverse side is up, and the interlining is on the upper side, and the bonding surface is downward. The effect of standard overlapping bonding is good, but the effect is low, and the fabric is easy to stick and dirty. The overcoat requires proper elasticity. The resin collar lining with a certain stiffness should be selected for the shirt collar, mainly to have a certain toughness. As can be seen from the above figure, the minimum stiffness is 5.4cm at 135 ℃ and the stiffness increases with the increase of temperature.
Bonding time the bonding effect of interlining fabric and fabric is affected by time to a great extent, because the flow of hot melt adhesive into fabric has a certain relationship between peeling strength and bonding time. The bonding of two-layer fabric depends on the hot-melt adhesive. The bonding time between the two layers is too short. The hot-melt adhesive is lack of melting and can not infiltrate the fabric well. Therefore, the peeling strength is low. However, if the pressing time is too long, a large amount of melt glue will infiltrate into the fabric. The length of pressing time should be selected according to the density and thickness of the cloth.
The pressure of bonding, the time of pressing and pressing, and the pressurization during bonding are mainly to eliminate the gap between two layers of fabrics, so that the hot melt adhesive can be squeezed into the fabric by external force. The pressure form of plate press is plane pressure, which makes the hot melt adhesive start to pressurize from the glass state (solid state) to the viscous flow state. The time of heating and pressing is synchronous, because the pressing time is longer, so the adhesion fastness is higher than that of rolling belt press, but it is easy to penetrate;
The pressure form of rolling press is linear pressure, which makes the fabric and hot melt glue heated at the same time and pass through the oven at the same time. Because at this time, the two-layer fabric that is not bonded tightly in the heating process, resulting in the interlining hot-melt adhesive can not be well bonded to the fabric, so the rolling belt press (except for those with precompression and preheating) is not as strong as the plate press, and has a more obvious effect on the fabric that is difficult to stick.
