Heilongjiang customized 3-strand twisted rope Indirect plate making method: the indirect film is first exposed, hardened with 1.2% H2O2, developed with warm water, and dried to make a strippable graphic negative. During plate making, the adhesive film surface of the graphic negative is closely attached to the stretched screen, the adhesive film is tightly attached to the wet screen by extrusion, the film base is removed, and the screen is dried by wind. customized 3-strand twisted rope Manufacturer Process flow: 1. Stretched wire mesh - degreasing - drying. 2 Indirect film - exposure - hardening - development - fitting - drying - revision - blocking. 3 Straight mixed plate making method: first, paste the photosensitive adhesive layer on the screen frame with water, alcohol or photosensitive adhesive, dry it with hot air, remove the substrate of the photosensitive film, and then print the plate. After developing, the screen plate is made.
Causes of bleeding. Some customers will customize the printing, but the PP fabric manufacturers sometimes have color bleeding when printing the PP ribbon, so the manufacturers should pay attention to the reasons when printing. Only by understanding these reasons can we reduce the occurrence of various conditions in the future use. What are the reasons for color bleeding when printing? There is dirt on the surface of the machine during printing. Cleaning up during production can reduce these problems.
If the weft needle is damaged, replace it or beat it with gauze; If the steel buckle is damaged, hit it with gauze or replace the steel buckle; The coir filament piece is damaged or the shutdown piece is damaged. Replace it with a new one. Causes of poor needle edge: uneven weft yarn thickness; The knitting needle is not properly laid, too long or too short; The pan head moves abnormally, sometimes tight, sometimes loose; The weft wheel is not round enough and deformed; The fixing pin of knitting needle is worn; Precautions: change another weft yarn; The knitting needle is longer or shorter according to the thickness of the ribbon. Generally speaking, the length of the knitting needle is just enough to remove the weft; Fix both sides of the pan head firmly, and do not let the pan head lean against the iron frame on both sides; Replace the weft wheel with a new one; Replace the fixed rod or go to processing.
One of the complete knowledge of printing types. There are many kinds of bag ribbon printing. Today, it is divided into two parts for everyone to talk about. If you like it, you can have a detailed look. It should be helpful to you. Here is the first part. Bag webbing transfer printing. The pigment is printed on the paper by printing method to make transfer printing paper, and then the color is transferred to the fabric by high temperature (heating and pressing on the back of the paper). It is generally used for chemical fiber fabrics, characterized by bright colors, fine layers, lifelike patterns, and strong artistry. However, this process is currently only applicable to a few synthetic fibers such as polyester. Transfer printing process is simple, investment is small and production is flexible. It is popular in the market at present But to be honest, compared with other types of printing, the price of this transfer printing is a little high, but it has a certain level.
The narrow Shenzhen ribbon or tubular fabric is made from various yarns. There are many kinds of belt fabrics, which are widely used in clothing, shoes, bags, industry, agriculture, military supplies, transportation and other industrial sectors. In the 1930s, it was all handmade workshops that produced exquisite pictures of ribbons. The raw materials were cotton thread and hemp thread. After the founding of the People's Republic of China, the raw materials for ribbon gradually developed to nylon, vinylon, polyester, polypropylene, spandex, viscose, etc., forming three major types of technology: weaving, knitting, knitting. The fabric structure includes plain weave, twill, satin, jacquard, double-layer, multi-layer, tubular and combined weave.
After the weft tube is formed by the yarn warp cylinder and weft winding, it is inserted on the fixed gear seat of the knitting machine, and the weft tube rotates along the 8-shaped track to draw the yarns to cross weave with each other. Usually, the number of spindles is even, the woven tape is tubular, the number of spindles is odd, and the woven tape is flat. Spindle weaving technology has been applied since old China. The number of spindles varies from 9 to 100 due to different equipment. The basic process of weaving is: bleaching and dyeing - weft rolling - weaving - off machine shearing - packaging. Since 1960, many technical innovations have been carried out on the knitting machine, mainly including the enlargement of peach plate diameter, the installation of an automatic stop device for breaking rubber bands, and the replacement of iron ingots with nylon ingots. The improvement of these equipment has increased the vehicle speed to 160~190 rpm, doubled the stand rate and greatly improved the product quality.
