Preparation method of a garment with automatic opening

A preparation method of a garment with automatic opening, comprising the following steps:

• S1) preparing a garment opening preform:
• the garment opening preform comprises:
• one or more functional layers each having a predetermined shape and size, made of hydrophilic material or hydrophobic material;
• a positioning layer having an inner side, and one or more of the functional layers are connected to a part of the inner side;
• a first connecting layer is arranged between the positioning layer and the one or more functional layers and is used for connecting the one or more functional layers and the positioning layer;
• a second connecting layer is connected at least to a part of the inner side of an area where the functional layers are not connected;
• an adhesive layer is connected to a side of the functional layers farthest away from the positioning layer;
• S2 the garment opening preform is used to prepare the garment with automatic opening:
• the garment opening preform is fixed on a fabric layer of the garment to be opened through the second connecting layer, the fabric layer, the adhesive layer and the functional layers are combined into a composite body, and the composite body is carved and opened to make the fabric layer have a penetrating incision stitch;
• removing the positioning layer, the second connecting layer and the first connecting layer, and obtaining the product;
• the number of each incision stitch is the same as that of the functional layers, the shape of each incision stitch is the same as that of one side or two interconnected sides of the functional layers, and the opening positions of each incision stitch correspond to the distribution positions of the sides of the functional layers.
