PURPOSE: To obtain a non-woven fabric which is used for deep drawing, exhibits highly stable dimensional stability in an impregnation process, can be drawn in a sufficiently large deep drawing ratio, and has an isotropic property.
CONSTITUTION: This deep-drawnable non-woven fabric is produced as a filament non-woven fabric, contains at least 30 wt.% of filaments having a low orientation degree and a rough fineness, has only mechanically been adhered, and has an isotropic property. The orientation degree of the filaments having the low orientation degree and the rough fineness is at least 80% based on the ultimate tensile strength elongation. Similarly, a resin-treated sheet-like prepreg produced from the non-woven fabric, a three-dimensional textile structure produced from the textile non-woven fabric which is useful for deep drawing and has been treated or not treated with a resin, a sandwiched material having the core of the three-dimensional resin-treated fiber structure, and the method for producing the articles.
