The yarn count of the second weft yarn 2 is 20S/1-60S/1, and the second weft yarn 2 comprises long stapled cotton and fine stapled cotton.

By adopting the antibacterial warm-keeping multilayer gauze velvet fabric in the embodiment, the weft yarns of the surface layer gauze adopt the first weft yarns 1, wherein the velvet yarns 13 are antibacterial warm-keeping cotton fibers, and the velvet yarns 13 present a fine velvet feeling on the surface of the fabric, so that the overall fineness of the yarns can be increased, and the fabric has good fluffy feeling and soft hand feeling. The core yarn is a high count yarn of 50S/2-140S/2, is thinner and is helpful for showing the pile feeling of the pile yarn 13 more obviously. The core yarn of the first weft yarn 1 is made of 100% cotton, the core yarn and the wool yarn 13 form functional chenille yarn, and the chenille yarn is applied to surface gauze to form a suede gauze layer. The suede gauze layer has good warmth retention property, skin-friendly property and air permeability, is not easy to cause the problem of skin allergy of a user, and is safer. And the chenille yarn with the yarn count of 3S/1-10S/1 formed by the core yarn and the wool yarn 13 is helpful for stabilizing the integral firmness of the yarn. The weft yarns of the bottom layer gauze adopt the first weft yarns 1 or the second weft yarns 2, so that the antibacterial warm-keeping multilayer gauze velvet fabric can be applied to a single-sided velvet fabric or a double-sided velvet fabric, and the use is more flexible.

For example, long staple cotton is used for the warp yarns 4 and fine staple cotton is used for the second weft yarns 2. Specifically, the warp 4 can be made into 20S/1-60S/1 compact siro spinning yarn by the siro compact spinning process.

In one embodiment, at least one intermediate layer of gauze is disposed between the top and bottom layers of gauze. Warp yarns 4 of the surface layer gauze, the middle layer gauze and the bottom layer gauze are the same in specification, and weft yarns of the middle layer gauze adopt third weft yarns 3. The yarn count of the third weft yarn 3 is 6S/1-16S/1, and the twist of the third weft yarn 3 is 290T/m-470T/m. The third weft yarns 3 adopt thicker yarns of 6S/1-16S/1, so that the overall thickness of the fabric can be increased, the static air stored in the middle layer can be increased, and the weaving efficiency can be improved. The warp yarns 4 of the surface layer gauze, the middle layer gauze and the bottom layer gauze have the same specification, so that the surface layer gauze, the middle layer gauze and the bottom layer gauze can be conveniently woven on a loom.

The two layers can be bound by upper layer warp 4 and lower layer weft (referred to as upper-connection and lower-connection method for short) or can be unidirectionally bound by interweaving the lower layer warp 4 and the upper layer weft (referred to as lower-connection and upper-connection method for short).

In other embodiments, besides the first weft yarn 1, the weft yarn of the surface layer gauze can also be combined by the first weft yarn 1 and the yarn with the count not lower than 40S/1, and the weft yarn of the surface layer gauze is formed by alternately beating up the first weft yarn 1 and the yarn with the count not lower than 40S/1. The surface layer gauze is finer and smoother through the yarns with the number not lower than 40S/1, the use proportion of the first weft yarn 1 in the fabric can be reduced, the overall cost is reduced, and the practicability of the fabric is improved. The yarns with the number of counts not less than 40S/1 adopt the yarns with the number of counts not less than 40S/1 in the second weft yarns 2.

The antibacterial warm-keeping multilayer gauze velvet fabric can be in a gauze structure with 2-12 layers. For example, when the antibacterial and warm-keeping multi-layer gauze-velvet fabric is 2 layers of gauze, the middle layer of gauze does not need to be woven, and the surface layer of gauze is directly connected with the bottom layer of gauze. For example, when the antibacterial thermal multi-layer gauze velvet fabric is 8 layers of gauze, 6 layers of middle-layer gauze need to be woven in addition to the surface-layer gauze and the bottom-layer gauze.

Except that the weft yarns of the surface layer gauze adopt the first weft yarns 1 with the velvet feeling, the weft yarns of the bottom layer gauze also can adopt the first weft yarns 1 with the velvet feeling, and the antibacterial warm-keeping multilayer gauze velvet fabric can be woven into a double-sided velvet fabric.

Specifically, according to actual needs, single-sided velvet or double-sided velvet is selected, and the number of layers of the antibacterial and warm-keeping multi-layer gauze velvet fabric is selected. For example, in the case of high requirement for heat retention, double-sided velvet may be used, that is, the first weft yarns 1 are used as the weft yarns of the surface layer gauze and the bottom layer gauze, and the number of layers of the middle layer gauze may be increased to further improve the heat retention.
