Example Embodiment
[0050] The second embodiment: The difference from the first embodiment is that PET / PET is selected in step S1, and the temperature of the hot rolling mill in step S5 is 110°C, which can produce a hard-handed, thin, and high-strength fabric. Acoustic stitching, and since the melting point of PET is 110°C, the temperature of the hot rolling mill is controlled at 110°C to ensure that PET / PER can melt and bond during hot rolling.
Example Embodiment
[0051] The third embodiment: the difference from the first embodiment is: PET / PP is selected in step S1, wherein the weight of PET is 70%-90%, the weight of PP is 10%-30%, and the temperature of the hot rolling mill is 150℃, select PET / PP composite materials for mixed spreading, and the weight of PP accounts for 10%-30%. The fabric produced is made of PET on one side and PP on the other side. When making a packaging bag, the material is When one side of PP touches, it can be heat-sealed by the sealing machine, and the packaging bag after heat-sealing has a firm structure and is not easy to be damaged. The melting point of PP is 150°C. Therefore, when the fabric enters the 150°C hot rolling mill, PP melts and other The fibers are bonded into sheets.
Example Embodiment
[0052] The fourth embodiment: the difference from the first embodiment is that PET / PERPE is selected in step S1, wherein the weight ratio of PET is 70%-90%, and the weight ratio of PETPE is 10%-30%. The temperature is 130°C, PETPE has a skin-core structure, the outer layer is PE with a lower melting point, and the inner layer is PET with a higher melting point, so that the melted PE can be used as an adhesive to bond the fibers together; the melting point of PE When the cotton web enters the hot rolling mill at 130°C, PE melts and acts as a binder to bond the fibers into a sheet-like cloth without adding other binders, thus realizing the lightweight of the cloth and making the cloth Lighter and thinner.
