| titleOfInvention | Manufacturing method of soccer ball fabric and single layer structure |
| abstract | The present invention relates to a method of manufacturing a soccer ball fabric and a single layer structure of the outer shell of which a polyurethane resin outer shell is made integrally with an underlay where mat paper is integrated on one or both sides of a high density nonwoven fabric. An impregnation process of impregnating a polyurethane resin impregnated tank with an underfloor mated with 1000-tenier polyester yarn by needle punching, and a solidification process of solidifying the polyurethane resin impregnated in the undergar in a water tank; Compaction process of compacting the processed underlay as compaction roller, and forming the outer skin to adjust the thickness as a braid while pouring a polyurethane resin solution containing 50 to 70% of DMF (dimethyl formamide) on the processed underground Process and the immersed fabric in the coagulation bath to form an open cell in the monolayer structure of the shell The open cell of the shell forming step, the fabric is subjected to a water washing step is a step of washing with water doengeot hayeoseo preparing a soccer ball fabric. |
