What backpack webbing means to bags: It is the end of the year again, and a large-scale movement in history is about to begin, which is the Spring Festival travel. In this wave of people returning home, all kinds of bags and backpack webbing have become a beautiful landscape. What's the meaning of backpacking. Bags are widely used in our daily life, especially in the days of Spring Festival travel. What people carry on their backs, what they carry on their hands, and what they hang around their necks, regardless of where they appear, are the knapsack ribbons that are closely related to the human body. It can be said that it is of great significance. Can you imagine the sour and refreshing feeling brought by the sudden rupture of the bag belt when you are carrying a full case of luggage to board the train?
The moisture in the air may cause spots in the car. When this kind of webbing contacts the clothes of passengers, the spots and colors on the luggage webbing will also be transferred to the clothes. Therefore, it should have anti spot fading characteristics, 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. Immerse the mixed colored cloth into the vessel 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.
Fuzhou Brocade ribbon manufactor The so-called water slurry is a kind of water-based slurry. It doesn't have a strong hand feel and coverage when printed on clothes. It is only suitable for printing on light colored fabrics. The price is relatively flat, and it belongs to a lower grade printing category. Customized Brocade ribbon manufactor But it also has an advantage, because it will not affect the original texture of the fabric, so it is more suitable for large-scale printing patterns. It is characterized by soft handle and bright color~~But there is a big disadvantage of the slurry. The color of the slurry is lighter than the cloth color~~If the cloth color is darker, the slurry can not cover at all.
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.
The convex and concave convex fabrics are compact and delicate on the front, with strip or pattern convex patterns, and rough on the back, with long floating lines. Wool fabric: single side woolen fabric, with the pile side being the front side of the fabric. For double-sided fleece fabric, the front side shall be the smooth and tidy side. Observe the selvage of the fabric: if the selvage is smooth, the neat side is the front side of the fabric. For double-layer, multi-layer and multiple fabrics, if the warp and weft density of the front and the back is different, the front side has a larger density or the front side has better raw materials.
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. 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.
