Or, it is used in various fields such as when attaching clothing parts such as patches to clothes.

ている特性を阻害すると云う問題点があった。On the other hand, urethane hot melt films are excellent in flexibility, elasticity, moisture permeability, cold resistance, flex resistance, toughness and the like. However, since this urethane hot melt film generally has a low melt viscosity, when it is inserted into a cloth or a foam sheet and heated by being inserted into the cloth or foam sheet, the resin of the melted hot melt film is woven into the stitches of the cloth or the voids of the foam sheet. The flow of the hot melt film was drastically reduced and thinned, or almost no layer of the hot melt film was formed. Therefore, the adhesive strength of the obtained laminate, that is, the adhesive strength between layers such as cloth and cloth, or cloth and foamed sheet, is weak.
In addition, since the resin of the melted hot melt film is impregnated in a large amount into the stitches of the cloth or the voids of the foamed sheet, the cloth or the foamed sheet becomes hard, discolored, or the texture is changed. There is a problem in that the characteristics possessed by those fabrics and foamed sheets are impaired.

When measuring the flow rate value by the temperature raising method under the conditions of a temperature rising rate of 3 ° C / min and a measurement interval of 2 ° C, the sample expands and the piston rises as the temperature rises, and the flow rate value is detected. The temperature at which the flow rate value was detected for the first time after the piston descended beyond the impossible range was defined as the outflow start temperature. The flow rate value (Q) is expressed by the following equation. Q = (X / 10) × (A / T) (cm 3 / sec) where T: measurement time (sec) X: amount of movement of piston with respect to measurement time T (mm) A: cross-sectional area of piston (cm 2 )

Because it's expensive
When it is inserted into a cloth, a foamed sheet or the like and heated, even if the thermoplastic polyurethane resin (A) in both outer layers melts and flows, the thermoplastic polyurethane resin (B) in the core layer melts and causes a flow. There is no such thing. As a result, most or all of the hot melt film does not melt and flow into the weave of the cloth or the voids of the foamed sheet, and the thermoplastic polyurethane resin (B) of the core layer has a layer shape. Maintains and enhances the interlaminar bond strength of fabrics, foam sheets, etc. laminated on both sides of the hot melt film. Also, the amount of resin that flows into the texture of the cloth or the voids of the foamed sheet is reduced,

積層化が困難となる。The outflow starting temperature of the thermoplastic polyurethane resin (B) used for the core layer is 2 times higher than the outflow starting temperature of the thermoplastic polyurethane resin (A) used for both outer layers.
It is necessary to raise the temperature by 0 to 100 ° C, preferably 30 to 90 ° C. If the difference in the outflow start temperature of the thermoplastic polyurethane resin between the core layer and both outer layers is less than 20 ° C, the heating temperature range for laminating and heating the fabric, the foamed sheet, etc. is narrow, and if the heating temperature is too low, the adhesive strength is If it is difficult to obtain, and if the heating temperature is too high, the thermoplastic polyurethane resin (B) of the core layer will also flow into the weave of the cloth, the voids of the foamed sheet, etc., and the adhesive strength will decrease. In addition, the characteristics such as flexibility of the fabric and the foamed sheet are also lost. On the other hand, if the difference in the outflow starting temperature of the thermoplastic polyurethane resin between the core layer and both outer layers exceeds 100 ° C., it becomes difficult to laminate the film by a coextrusion method or the like.

For example, when the size of the weave of the cloth laminated on both outer layers or the size of the voids of the foamed sheet is different, the resin with a low outflow starting temperature has a large weave on the side of the fabric having a small weave or the foamed sheet having a small void. If the cloth or foam sheet with large voids is made to contact the resin with a high outflow starting temperature, or if the cloth or foam sheet is heated from only one side, it will flow to the heating side. It is preferable that the resin having a high starting temperature is brought into contact with the resin having a low outflow starting temperature on the side which is not heated.
