[III]を得た。Example 3 Meta-aramid fiber [decomposition starting temperature is 400 ° C. or higher, L
OI value of 33%] 1500dr / 750fil multifilament yarn, warp and weave density 10 × 10/25
mm plain weave fabric (porosity 22%) was made. On the other hand, a short fiber having a fineness of 2 dr and a fiber length of 51 mm of the above meta-aramid fiber is used, and an average weight of 350 is passed through a card or a random webber.
A non-woven fabric laminate was prepared by making a fiber web of g / m 2 and laminating it on both sides of the plain woven fabric and subjecting it to needle punch entanglement treatment to the same extent as in Example 1 so as not to hinder movement. Nonwoven fabric structure having a smooth surface after entanglement treatment from both sides of the nonwoven fabric laminate under the same high-pressure hydroentanglement treatment condition, followed by drying and pressing with a calender roll having a surface temperature of 160 ° C.
