Detailed Description
The invention will be further described with reference to the drawings and specific examples.
Example 1
This embodiment will be described in detail with reference to fig. 1. The preparation method of the antibacterial anti-mite leather base fabric comprises an outer layer fabric 1, an anti-mite fabric layer 2, a base fabric layer 3, an antibacterial fabric layer 4 and an inner layer fabric 5 which are sequentially arranged.
The preparation method comprises the following steps:
step S1, sequentially stacking an outer layer fabric 1, an anti-mite fabric layer 2, a base fabric layer 3, an antibacterial fabric layer 4 and an inner layer fabric 5, and arranging a layer of hot melt adhesive net film between two adjacent layers of fabrics.
And S2, placing the stacked layers of fabrics and the hot melt adhesive net film in an oven until the hot melt adhesive net film is melted, wherein the temperature in the oven is 105-115 ℃.

Specifically, five-piece satin is adopted, antibacterial polyester yarns are used as warp yarns in the outer layer fabric 1, and nylon polyester mixed filaments are used as weft yarns.
Further, the nylon and polyester mixed filament yarn comprises polyester multifilament yarns and nylon 6 multifilament yarns which are arranged in parallel and are provided with network points which are arranged at intervals, the fineness of the polyester multifilament yarns is 35-60D/48-96F, and the fineness of the nylon 6 multifilament yarns is 50-100D/24-36F. In the embodiment, the fineness of the polyester multifilament is 60D/96F, and the fineness of the nylon 6 multifilament is 50D/36F. Specifically, the polyester multifilament and the nylon 6 multifilament are arranged in parallel and jointly pass through a network nozzle, and the monofilaments in the polyester multifilament and the nylon 6 multifilament are intertwined together at the network nozzle under the action of high-pressure air flow, so that the two multifilaments are bonded together, the bonding position is a network point, the network degree is 50 per meter, and the network degree is the number of network points per meter.
