And S4, in the laminating and embossing forming stage, embossing and laminating the PVC surface layer and the yarn cushion layer, and then performing high-temperature hot-pressing vat operation, wherein the vat operation temperature is 145 ℃.
In S5, in the winding process, the pressures of the rubber winding roller, the silica gel winding roller and the bending winding roller are all 3.5 kg/cm, the winding traction tension is 3 kg/cm, and the winding speed is 12.5 m/min.
The thickness of the produced tablecloth is 0.25mm, and the width of the produced tablecloth is 130 cm-155 cm.
The overall performance of example 3 is best, combining the physical and chemical properties of the tablecloths obtained in comparative examples 1-5.
Example 1 compared to example 3, the tablecloth prepared in example 1 has poor softness and comfort and poor overall imitation fabric effect, because the PVC content in example 1 reaches 32.5%, so that the plasticity of the product is poor.
Compared with the embodiment 3, the tablecloth prepared in the embodiment 2 has the defects of unclear pattern effect level and poor decorative effect, because the tablecloth is not cooled by a cooling device after the cloth pattern is formed, the cloth pattern forming effect of the product is not ideal.
Example 4 compared to example 3, the tablecloth prepared in example 2 is not soft and comfortable enough for the first time, and has poor imitation cloth effect and poor reality degree because the thickness of the PVC surface layer is too large before lamination, which causes the yarn cushion layer not to protrude and the effect of the fabric texture formed on the PVC to be poor.
Example 5 compared to example 3, the tablecloth obtained in example 2 has a poor cloth-imitated effect and a poor degree of reality, because the number of the open patterns of the cloth pattern reaches 100 meshes, the number of the open patterns is low, and the cloth pattern effect is poor.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
