Glue works on cement board but not on textile

I hang vintage Asian textiles over doorways and windows. One new window is framed in Hardie Plank and I could not get push pins to stick in, which is what I'm able to use at the doors and windows with original wood framing. I bought this Velcro strip and it worked fairly well. The sticky side stuck to the window frame perfectly. However, although the sticky side seemed to stick to the textile, and I mounted it on the window frame, it fell down. I thought at first my cat had pulled it down but I discovered that the glue did not hold onto the fabric. I sewed it to the fabric, using light weight thread and long stitches. It has held up now for several days so I think the problem is solved. This package was more than enough for the project and I will save the remainder.
