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.
Moisture in the air may cause special Brocade ribbon When the webbing contacts with the passengers' clothes, the spots and colors on the luggage webbing will also be transferred to the clothes, so Changchun Brocade ribbon It shall have anti spot fading property, which is also called spot color fastness. The spot color fastness test includes multi fiber test and filter paper test. The multi fiber test is to clamp a sample of tissue belt between two layers of colored cloth. Clamp Brocade ribbon Immerse the cloth with distilled water and completely wet it. Then squeeze the water out of the extruder, and then clamp these colored cloth wrapped with selvedge webbing into the plexiglass sheet, put it into the sample holder, and lock the sample holder. This rack is placed in a high and low temperature box at a certain temperature, and after reaching the specified time. Take out the sample and hang the colored cloth.
What are the characteristics of the edging webbing: moisture retention: because the pure cotton edging webbing is a poor conductor of heat and electricity, the heat conductivity coefficient is extremely low, and because the cotton webbing itself has the advantages of porosity and high elasticity, a large amount of air can be accumulated between the webbing, and the air is a bad conductor of heat and electricity, the pure cotton webbing has good moisture retention, and people feel warm when using the pure cotton webbing. Hygiene: pure cotton edging webbing is a natural fiber, which is mainly composed of cellulose, a small amount of waxy substances, nitrogen and pectin.
Silk fabrics have high porosity, so they have good sound absorption, dust absorption and heat resistance. Therefore, in addition to making clothes, it can also be used for interior decoration, such as silk carpets, tapestries, curtains, wall coverings, etc. Decorating a room with silk ornaments can not only make the room spotless, but also keep the room quiet. Due to its hygroscopicity, moisture release performance, moisture retention, air absorption and porosity, it can also adjust the indoor temperature and humidity. Silk fiber has small thermal denaturation and is relatively heat-resistant. When it is heated to 100 ℃, it is only about 5-8% brittle, and the thermal variability of most synthetic fibers is 4-5 times greater than that of silk. The combustion temperature of silk is 300~400 ℃, which is a non combustible fiber, while the combustion temperature of synthetic fiber is 200~2600C, which is flammable and fusible. Therefore, using silk fiber as the raw material for interior decoration can not only play the role of sound absorption, dust absorption, heat preservation, but also play the role of flame retardant.
Not only the production process is complex, but also the packaging process is very complicated. Only the webbing that has passed the inspection can be packaged out of the warehouse, otherwise it will be treated as defective products. The specific packaging process is as follows: 1. The process control method: 1. The surface of each winding tape must be smooth and flat (except for special webbing); Those who cannot be involved in substandard products shall be held accountable according to the seriousness of the case. Knot: ≤ 3/100Y, ≤ 2/50Y; Short code: ± 0.5/100Y; Each knapsack strap must have the label of the tape coiler. Inspection according to the customer's requirements: for example, 336, 217, 115, 314, 108, 114, 384, 206, 419, 122 adhesive paper and rubber hose, no pins can be used;
At present, more than 90% of the market is made of cotton polyester thread or polyester cotton thread, but there are few pure cotton threads in the market, and the price is surprisingly high! Polyester cotton yarn just neutralizes the advantages of pure cotton and polyester, depending on the composition of polyester in cotton. Generally, the yarn of cotton ribbon is made by adding a small amount of polyester into cotton, so that it can have the advantages of pure cotton and polyester cotton. It is easy to wash, heat resistant, alkali resistant, moisturizing, sanitary, wear-resistant, not shrink, not easy to wrinkle, not easy to deform, not easy to stick wool, and so on! The key is that the proportion of cotton and polyester is appropriate! The identification method of pure cotton webbing and polyester cotton webbing is simply to take the cut thread and burn it. If there is any hard block, it is polyester cotton yarn containing polyester, and if it is completely reduced to ashes, it is authentic pure cotton.
