Basic introduction Chinese name: elastic band elastic thread mbth: elastic band type: clothing accessories creation time: 18 12: the original name of a hat factory: origin, use, classification, material selection, cutting machine, principle and equipment information. The origin of elastic band first appeared in 18 12. The real rubber band is an accidental invention of chemist Ma Shengtuo and inventor Hancock in the experiment of extracting rubber concentration in 1820. Ma Shengtuo first used the characteristics of rubber to sandwich rubber between two layers of fabric and invented waterproof tape. Hancock obtained the original patent of rubber band at 1820. His elastic band is actually the elastic band of clothes or boots, which is fixed with adhesive. 1876, elastic bands are used in women's underwear. In the same year, a ribbon report article said: "In Paris, you can see several recent inventions, one of which is an elastic band made of rubber. People use elastic bands instead of spiral copper wires to make shoulder straps, gloves and corsets for women. It is very suitable and will not tear clothes or grow patina like a steel wire spring. " Fabric can be plain weave, double weave, twill weave, double weave, double warp weave and jacquard weave. Woven elastic bands are compact in texture and diverse in variety, and are widely used in clothing cuffs, hems, bras, garters, belts, shoes, sports protection and medical laces, handicrafts, office stationery, industrial products, household products and other products. Elastic band, as garment accessories, is especially suitable for underwear, trousers, baby clothes, sweaters, sportswear, nursery rhymes, wedding dresses, T-shirts, hats, busts, masks and other garment products. Its uses include plain weave, double weave, twill weave, double weave, warp double weave and jacquard weave. Woven elastic bands are compact in texture and diverse in variety, and are widely used in cuffs, hems, bras, garters, belts, shoes, sports protection, medical laces and so on. Classification is divided into woven elastic band, knitted elastic band and knitted elastic band according to different knitting methods. Woven elastic belt is made of cotton or chemical fiber as warp and weft and interwoven with a group of rubber yarns (latex yarns or spandex yarns) according to certain rules. Knitted elastic belt is knitted by warp knitting and weft insertion. Under the action of crochet or tongue needle, warp threads are nested in knitting chains, and weft threads are arranged in a row in each knitting chain to connect scattered knitting chains into belts, and rubber threads are covered by knitting chains or clamped by two groups of weft threads. Knitted elastic band can weave all kinds of small patterns, colored stripes and crescent edges, and the texture is loose and soft. The raw materials are mostly nylon stretch yarn, and the products are mostly used in women's bras and * * *. Woven elastic belt, also known as spindle woven elastic belt, is made by weaving warps around rubber threads through spindles according to the "8" track. The grain of the belt is herringbone, the bandwidth is generally 0.3 ~ 2 cm, the texture is between woven and knitted elastic bands, and the color is monotonous, which is mostly used for clothing. According to the general classification, it can be divided into the following categories. Moving elastic belt-The yarn meridian tube is wound into a weft tube, and then inserted into the fixed tooth seat of the knitting machine, and the weft tube rotates along the 8-shaped track, thus pulling the yarns to interweave with each other. Medical elastic band-Jacquard polyester with pH between weak acid and neutral will not cause skin itching, nor will it damage the skin in nominal weak acid environment. Nylon mixed elastic band-under dry and wet conditions, it has good elasticity and wear resistance, firm size and small shrinkage, and is a good auxiliary material for clothing. Wide elastic band-is a flat elastic band, which is interwoven by traction yarn and odd spindles. Ribbon rigid belt-single-sided jacquard or double-sided jacquard, elastic band and ribbon feel excellent, with beautiful color and no wear on materials. The main jacquard belt-printed elastic band-elastic band is printed with different patterns and patterns, and with different base bands, different achievements and changes have been made, including thermal transfer printing and screen printing. Color elastic belt-Woven by warp knitting and weft insertion. Under the action of crochet or tongue needle, warp threads are nested in knitting chains, and weft threads are arranged in a row in each knitting chain to connect scattered knitting chains into belts, and rubber threads are covered by knitting chains or clamped by two groups of weft threads. Non-slip elastic band-has the characteristics of high strength, strong impact resistance and not easy to break. Elastic band, Jiuqing Enterprise Co., Ltd., has good heat resistance and wear resistance. Polyester elastic band-an ideal raw material for knitting (weft knitting, warp knitting or weaving), suitable for making clothing fabrics, bedding and decorative articles. Elastic belt-warp-weft knitting is adopted. In the process of looping, the cylinder of looping yarn and sinking arc are used to connect the non-woven warp and weft into a whole, which becomes a warp-inserted weft-inserted rope. Buttonhole elastic band-also known as buttonhole elastic band or adjusting elastic band. The main raw materials are latex silk and low elastic silk, which are used for maternity clothes, children's clothes and other adjustable sizes. Material selection Material selection and production: Elastic bands tend to use nontoxic and harmless TPU as raw materials. Auxiliary high elasticity additives can be added to enhance its elasticity. Elastic belt shears are divided into ultrasonic semi-automatic elastic belt shears and ultrasonic full-automatic elastic belt shears. The principle of shearing machine The principle of ultrasonic elastic belt shearing machine (ultrasonic belt cutter) is the combination of ultrasonic welding technology and traditional shearing. When the ultrasonic generator is working, the ultrasonic energy is transmitted to the welding head through the ultrasonic transducer, which generates violent vibration and friction with the knife die, thus achieving the shearing effect and making the cut products more beautiful, firm and efficient. Equipment information machine parameters: frequency: 20KHZ voltage: 220V output power: 1500W appearance size: 800*600* 1350mm weight: 125KG efficiency: 60-90 times /min machine features: 1. Gantry design of the nose. 2. The ultrasonic frequency is 20KHZ with little noise. 3.PLC program control, simple and intuitive operation. 4. Adjust the length and speed at will. 5. The acrylic protective cover at the nose is safe and has good visibility. 6. The rotation design of the tool rest can adjust the angle of the tool at will. 7. The cut mold can be replaced at will, and the installation is simple and convenient. 8. The whole machine has exquisite structure, reasonable design and beautiful appearance. 9.
