Ribbon manufacturers give you a summary of the basic process and process of the dyeing workshop: polyester fiber into the belt-pre-washing-pre-drying-coloring tank-pre-drying (infrared)-high-temperature baking-post-washing (reduction cleaning )–After drying–drop off the belt. The role of infrared pre-baking: the dye molecules are initially attached to the fiber to prevent the appearance of color and flower problems. The role of high-temperature baking: Make the dye molecules fully enter the inside of the fiber to complete the process of dyeing the fiber with the dye.
The role of reduction and cleaning: to decompose the excess dye molecules to ensure the color fastness of the product. Nylon fiber enters the belt—coloring tank—steaming with hot steam—after washing—after drying—removing the belt and the function of steaming: the acid dye molecules can fully react with the corresponding functional groups in the fiber to complete The process of dyeing fibers with acid dyes. The function of water washing: remove the dye molecules that have not reacted completely, and ensure the color fastness of ribbons, ribbons and other products.
I have been in contact with the polyester webbing for a long time, and I have more experience. I can feel the quality of the webbing by feeling. This way of looking at the webbing is wrong. How to distinguish the quality of the webbing? Is it correct? First of all, look at whether the texture of the taperon webbing is wrong, and whether the size of the pattern text is correct. Whether the effect of each picture and text is the same as the original one or the original picture, it means that the tape is woven well, because it can meet customer needs from the picture and text.
Secondly, look at the color of the polyester webbing, the color is generally the color color system. The color comparison here is the color number of the original version. There is no special explanation for this. It can only be judged by the senses. However, if the color is normal, there will be a professional color matching light to match the color. If it is a clothing category, D65 is commonly used. Light-to-color
Looking at the feel of the tapen webbing again, the feel of the tapen webbing is an important content used to identify the quality of the tapen webbing. Specifically, the psychological reaction of the feeling of touching the tapen webbing with the hand, due to the different varieties of the tapen webbing, and the different quality, the hand-feel effect of the tapen webbing is also quite different. Hand feeling has the following aspects: 1 whether the body bone of the polyester webbing is firm and loose; 2 the smoothness and roughness of the webbing surface; 3 the softness and hardness of the webbing; 4 the thinness and thickness of the webbing; 5 the thickness of the webbing Whether the surface of the tape is smooth and whether the seaming is beautiful; whether the whole strip of the tape is straight without bending
Generally, the pattern on the front side of the webbing manufacturer is clearer and more beautiful in color than the back side. The front patterns of plants and color-matching patterned fabrics with a striped appearance must be clear and pleasant to the eye. This pattern is especially obvious when weaving jacquard belts. The convex and concave-convex fabrics are dense and delicate on the front, with strips or pattern reliefs, while the back is rougher and has longer floating lines. Raised webbing: single-sided raised fabric, the raised side of which is the front side of the fabric. For the double-sided pile fabric, the pile is smooth, and the neat side is the front side.
