The fireproof woven belt ultrasonic cord cutting machine adopts a PLC control console, which automatically feeds materials and has electronic eye tracking and scanning for more accurate computer counting. It has high accuracy, fast speed, simple, fast, and efficient length adjustment. This equipment is widely used in packaging, gift, clothing and other industries, and its unparalleled cutting effect is favored by customers. There are two types of climbing ropes: main rope and auxiliary rope. The main rope has a length of 60-100 meters, a diameter of approximately 10 millimeters, and a weight requirement of 0 per meter. Approximately 08 kilograms, with a tensile strength requirement of no less than 1800 kilograms. In the past, jute was often used for production, but now nylon fibers have been used as raw materials. There is also a main rope with a diameter of 8-9 millimeters, weighing 0 per meter. 06 kilograms, with a tensile strength of not less than 1600 kilograms, used for climbing steep rock walls. The elastic waistband has good low-temperature flexibility and excellent tensile resilience, and can be used for a long time to maintain consistency. Breathable elastic band, also known as elastic line or rubber band line, can be used as a bottom line for clothing accessories, especially suitable for underwear, pants, baby clothing, sweaters, sportswear, rhyme clothing, wedding dresses, T-shirts, hats, bras, masks and other clothing products.
1. Spandex
Polyurethane fiber, scientific name, melts and burns near a fire. When burning, the flame is blue. When leaving the fire, it continues to melt and burn, emitting a special pungent odor. The burnt ash is soft and fluffy black ash.
2. Nylon and Polyester
Nylon (nylon), also known as polyamide nanofibers, quickly shrinks and melts into a white gel near the flame, forming droplets and bubbles. When burned, there is no flame, making it difficult to continue burning without this flame, emitting different celery flavors. After cooling, the light brown melt is not easy to grind.
The scientific name of polyester fiber is polyester fiber, which is easy to ignite and is melting and contracting near the flame. When burning, the melting edge is black smoke, yellow flame, and fragrant. The burnt ash is a black brown hard lump that can be broken with fingers.
3.Acrylic acid and polypropylene (PP)
Polyacrylonitrile fiber melts, contracts, and softens when close to a large fire. After the fire, black smoke is emitted, and the flame is white. It quickly burns from behind the flame, emitting a sour smell of burning meat. The burning ashes are irregular black hard blocks, which are twisted and fragile by hand.
Fireproof woven polypropylene fiber, also known as polypropylene fiber, melts near flames and is flammable. It slowly burns away from the source of fire, emitting black smoke. The flame is yellow at the top and blue at the bottom, emitting a smell of oil. The ashes after combustion are hard, round, yellowish brown particles that are fragile when twisted by hand.
