Is superfine fiber cloth a patent in Gu Jia?

Microfiber cloth is a patent of Gu Jia. Gu Jia's microfiber cloth is his own patented product, which is soft and delicate, breathable and scratch-resistant. I've been there myself. According to relevant public information, Gu Jia's patented fabric is microfiber fabric, which is wear-resistant and scratch-resistant, and easy to handle. Although the three-layer fabric is thick, it can also blow balloons through the fabric, and the fabric density is relatively high. If the density is high, water will not penetrate easily, and the formaldehyde content is only a quarter of that of baby diapers.
