Diving suit, the Chinese name is neoprene rubber, diving material is a synthetic rubber foam, feel delicate, soft, elastic, with shock-proof, insulation, elasticity, impermeable, breathable and other characteristics, is currently widely used in the manufacture of diving equipment, and we usually use mouse pads, backpacks, soles and so on are also made of diving materials.

1. Introduction and characteristics of SBR/ CR-Elastic salad /CR skin

It is an ordinary diving material, the middle interlayer is neoprene rubber, both sides are laminated with N cloth, the glue content can reach 50%, generally seen in the market for this material, because of the low cost and moderate flexibility, diving shop in the O teaching class especially favored, suitable for novice divers to use. In diving materials, the elasticity index is generally measured by how many centimeters, and the elasticity index of SBR is 3-4 centimeters, during the journey, even if it is loaded into the suitcase for a long time, as long as it is taken out and placed, it will soon return to its original shape.

Super elastic salad is super elastic diving material, the middle interlayer is neoprene rubber, the surface frame cloth fitting, the bottom pull gauze fitting, the rubber content is 100%, as the name suggests, the elasticity can reach 6-8 cm, the resilience is very fast and durable, and then the designer considers the material characteristics and application scenarios when designing and publishing, the general super elastic diving suit will be smaller. So when you get the clothes, you must put them on and then decide if the size fits you after you get them out.

Second, the source of diving materials

At present, there are three main kinds of diving suits sold in China, one is yamamoto diving material imported from Japan, the other is yako diving material imported from South Korea, and the third is Taiwan diving material sheico. The three kinds of diving materials are slightly different, especially in terms of elasticity, recovery, price, etc., there are differences, because you can't get first-hand resources and it is not good to involve more manufacturer information, eight ye point to the end, interested diving friends can consult themselves.

Third, diving material sewing process

The mainstream of the production of diving materials in the market is generally divided into four needles and six threads and blind sewing process two sewing techniques.

Four, needle six thread:

The ISO607 stitch is composed of four surface wires, one base wire and one taut wire. The four needles and six threads have the advantages of beautiful, flat and seamless, and are often used in the production of diving suits below 3mm. This is a kind of advanced technology, features: the seam is firm, more beautiful lines, the cutting edge is neat and not wrapped, the stitch is beautiful and dynamic, and it can be perfectly stitched at one time in multiple processes, and the four needles and six threads are also dedicated to the unique high elasticity, flat and high strength stitching effect.

Sewing process:

It is generally used for the production process of diving suits above 3mm, and if you choose the blind sewing of the light leather material, you can only sew the inner layer in order to ensure the smooth surface. Most of them are single-needle double-thread chain stitch, which features: the stitch is more beautiful, and the stitch is not easy to fall off, and it is more firm because of the use of dark stitching, the sewing fabric cannot see the sewing stitch from the surface, so that the clothing can maintain the original neat and beautiful, and prevent water from entering.
