MANUFACTURING METHOD OF MOLDING MATERIAL USING CLOTH FIBERS

To provide a manufacturing method of a molding material using cloth fibers, which can easily prepare a molding material in which cloth fibers are uniformly mixed.SOLUTION: A manufacturing method of a molding material using cloth fibers comprises: a first pulverizing step (step 1-1) for pulverizing a cloth into a cotton-like material; a compression step (step 1-2) for compressing cloth fibers pulverized by the first pulverization step into a compressed body; a second pulverizing step (step 1-3) for pulverizing the compressed body solidified by the compression step into a powder-like material; and a molding step (step 1-4) for molding a material obtained by heating and melting a cloth powder pulverized in the second pulverizing step mixed with a thermoplastic synthetic resin.SELECTED DRAWING: Figure 1 【課題】布繊維を均一に混合した成形材を容易に作成することができる布繊維を用いた成形材の製造方法を提供すること。【解決手段】布をわた状に粉砕する第１の粉砕工程（ステップ１－１）と、第１の粉砕工程によって粉砕した布繊維を圧縮して圧縮体に固める圧縮工程（ステップ１－２）と、圧縮工程によって固めた圧縮体を粉末状に粉砕する第２の粉砕工程（ステップ１－３）と、第２の粉砕工程によって粉砕した布粉末を、熱可塑性の合成樹脂に混合して加熱溶融し、成形する成形工程（ステップ１－４）とを有する。【選択図】図１
