【発明の名称】立体構造物成形用素材及びこれを用いた立体構造物の製造方法
Document Type and Number:
Japanese Patent JP2847214
Kind Code:
B2
Abstract:
PURPOSE:To obtain the subject material, having a specific dry heat shrinkage factor and opening angle and suitable for producing a steric structure such as bag or cover by blending conjugate filament yarn containing a low-melting point polyester as a sheath and partially fusing the sheath. CONSTITUTION:The objective material, obtained by producing sheath-core type conjugate filament yarn from (A) polyethylene terephthalate as a core component and (B) a low-melting polyester containing preferably 15-35mol% copolymerized isophthalic acid, etc., and regulated to 130-210 deg.C melting point as a sheath component at preferably (6:4)-(2:8) joining ratio of the components (A) to (B), mixing >=40wt.% resultant conjugate filament yarn, preparing a woven or knit fabric and heat-treating the obtained fabric at a temperature preferably >=10 deg.C higher than the melting point of the component (B) and lower than the melting point of the component (A) and providing <=5% dry heat shrinkage factor at 220 deg.C and <=60 deg. opening angle.
