At present, many daily necessities are made of water-based synthetic leather. When cutting with water-based synthetic leather, the following five precautions need to be taken.
Water based synthetic leather with skin texture
1. First, understand the structure of water-based synthetic leather products. For example, for leather shoes, first determine the front piece, toe cap, carcass pad and leather; the whole tongue extends left and right, and other parts such as Poria eye, outer hind hoof, and shoe feather extend up and down. The carcass pad extends left and right to facilitate sewing and fitting, that is to say, the whole upper is tied up, only allowed to be widened, not allowed to be lengthened
2. Understand the cutting area and leather selection
3. The first knife to be cut is fixed knife, which saves the most material. The edge distance between knife and knife is 0.5 or zero. The use of defective skin, such as scars and marks, is generally cut and overlapped. The marks should be arranged from the inside to the outside, and from the outside, so that the inside cannot be arranged
4. Pick up the knife for the edge material of water-based synthetic leather; if it is impossible to pick up the knife for the larger edge material, it is necessary to select a proper knife, and the big knife should be matched with the small knife
5. The front end of the panel shall be arranged in order, otherwise, it is wasteful to cut the first edge. It is conceivable that the 6-12 layers of this material are wasteful
