[0015] The utility model will be further described below in combination with the drawings and examples. Examples

[0016] As Figure 1 , 2 The utility model discloses a four-way stretch fabric of imitating air layer, which comprises a high-F number nylon yarn, a waterproof layer and a suede layer.

[0017] The main body layer fabric raw material specification: the surface warp yarn and the surface weft yarn adopt 70D / 68F semi-dull nylon package 40D spandex yarn; the inner warp yarn adopts 70D / 68F semi-dull nylon package 40D spandex yarn, and the inner weft yarn adopts 140D / 136F semi-dull nylon two and 30S siro spun composite nylons to form a composite yarn.

[0018] The fabric on the market is roughened or napped on the reverse side to achieve the effect of warmth and comfort in wearing, but the consumer is not comfortable due to the adhesion of the nap caused by sweating of the human body during wearing, so the Italian Lafer napping machine is used for napping in the utility model, the napping layer of the acrylic wool formed is delicate, the nap degree is high, the touch feeling is softer and more comfortable, and the skin is more intimate.

[0019] The waterproof layer is a fluorine-free coating film, specifically a silicone (methyl) acrylate polymer, which is a polymer of non-fluorine (methyl) acrylate monomer repeating units and silicone macromonomer repeating units.
