The ribbons we are familiar with that is very versatile and can be seen everywhere in daily life, but how much do you know about the production technology of ribbons? Today we mainly introduce the two production techniques of ribbons.
Firstly, the woven is that the warp and weft of the thread are interlaced, and the yarn is warped and warped to form a bobbin, the weft is shaken into a shuttle, and the belt is woven on the loom. 1930s , the woven belt was a hand-drawn wood loom or an iron wood loom. From the early 1960s, the 1511 loom was converted into a loom, and it is still widely used. Because of the small width of the belt, the weaving method is different, there are single, double, dozens of different, single-layer and double-layer. In the 1970s, due to the promotion of continuous dyeing and ironing machines for belts, the processing of colored belts developed from the traditional process of dyeing and weaving to weaving and then dyeing, weaving and bleaching, and the continuous processing after ironing. The ribbon technology became mechanized.
Secondly, the knitting. After knitting, the yarn is formed into a weft tube by warping and winding the weft, which is inserted into the fixed gear seat of the knitting machine, and the weft tube rotates along the 8-shaped track to draw the yarns to cross each other. Usually the number of spindles is even, and the woven belt is tubular, and the number of spindles is odd, and the woven belt is flat. The basic process of weaving is: bleaching and dyeing-weft rolling-weaving-falling machine cutting-packaging. Since 1960, many technological innovations have been made to the braiding machine, mainly including the enlargement of the diameter of the peach board, the installation of an automatic parking device for broken rubber bands, and the change of iron ingots to nylon spindles. With the improvement of equipments , the speed of that has in increased to 160-190 rpm, doubled the stand rate, and greatly improved the product quality. Weaving can not only weave belts, but also weave ropes. Tubular belt is a kind of braided rope. The diameter of 1 to 4 cm is called rope or rope, the diameter of more than 4 cm is also called rope, and the diameter of more than 40 cm is generally called cable .
The processes are common in production technology processes of ribbon.With the development of production and technology, the production technology of ribbon is also constantly progressing and developing.
