Novel thermal fabric
The utility model discloses a novel warm-keeping fabric, which belongs to the textile field and comprises a first base cloth layer, a second base cloth layer and a hot-pressing layer connected between the first base cloth layer and the second base cloth layer, the hot-pressing layer has a wave-shaped structure, a first air chamber is formed between the hot-pressing layer and the first base cloth layer, and a second air chamber is formed between the second base cloth layer and the second base cloth layer. A second air chamber is formed between the hot-pressing layer and the second base cloth layer, the first base cloth layer comprises first yarn, the first yarn is provided with a first cavity, the second base cloth layer comprises second yarn, the second yarn is provided with hollow particles, and the wave-shaped structure can maintain the distance between the first base cloth layer and the second base cloth layer. The first yarn in the first base cloth layer retains air through the first cavity, the second base cloth layer serves as the inward face of the garment, in order to adapt to the characteristic that the inward face of the garment is prone to being pressed, hollow particles are adopted to retain air, and the hollow particles are more stable than the first cavity. After being washed, the fabric is not easy to collapse and is easier to clean.
