Is the "wire" circle, then pay more attention to the interface part of the circle, some circles are "alloy" die-casting, there is no interface, this kind of metal rest assured! Second, zipper pocket: Zipper is composed of three parts, zipper, slider and pull the card! Zipper on both sides are generally nylon material, the middle of the "zipper teeth" mainly divided into "plastic teeth" and "metal teeth" two, how to identify a zipper is good or bad? First, see "zipper teeth" with or without shedding (subtleties); Second, pull the slider several times to see if the slider and the zipper connection is smooth; Third, after tightening the zipper, bending part of the zipper, Strength can be a little larger, bending at the same time see if there is no crack (zipper teeth), no crack is good; Fourth, look at the pull between the licensing and the gap between the slider, the gap is large, the pull tab will be easy Cracked with the slider! Because pull the card is fixed to the slider to go up. Third, the bag body: Some parts of the bag body industry terms and commonly known as not the same, the bag body called the "main ingredient", the handle and the bag there are edging fabric called "ingredients." The front of the bag is called "front panel" and the back is called "rear panel". The left and right sides of the bag are called "side panels". The pockets outside the bag are called "external pockets". The inner pockets are called "inner pockets" The pocket is called "septum pocket", the pocket cover is called "hijab", the buckle connected with the bag body is called "Lizai", and the two parts of the handle and the pocket are called "ear-ear". The structure of the bag body is generally three layers, 1, the outside is the fabric; 2, the middle layer is bottom of the backing PVC or cardboard, sponge, "light plastic", "plastic back", "non-woven" and "bran paper" Material, the general feel of the hand can be identified, feel harder sticky cardboard or thick PVC, neutral sticky is the back of plastic, paper branded paper or softer PVC, soft sticky is the light plastic, Non-woven or sponge; 3, the innermost layer is lined with lined nylon material (190D, 210D, 240D and so on specifications) cotton and "satin" (a silk fabric characteristics) and so on. Left and right sides of the bag body with the same structure. Generally sticky at the bottom of the bag are thick "bottom PVC"! Fourth, fabric: Fabric points: natural leather, PU leather, PVC material, nylon material, canvas, plush fabric and so on. Related articles: Select the right travel bag from the fabric, wheels, trolley Natural leather is divided into "first layer of skin" and "second layer of skin", "first layer of skin" is processed from some complete high quality animal skin, used to do high school Stalls of the fabric; "two-tier skin" is a number of animal skin and animal skin the lowest layer of material processing, used to make low-grade package of fabric. PU leather and PVC material are artificial leather, PU leather material used is better than the PVC material, in addition to the quality of artificial leather and the production process has a great relationship, and some production process is very good artificial leather, the price is very expensive. Leather color, feel and some special effects Shu Shu depends on the production process! The plush material mainly looks like real wool or wool, which can be distinguished by its feel. The feel of real wool is the same as touching the cat's body. The quality of nylon material and canvas mainly depends on the "density" of the material and the clothing Industry knowledge of people will identify their good or bad! Five, hardware: Hardware generally divided by material "wire" and "alloy" two, then how to identify it? With a magnet on it, can tighten the wire is tight, tight suction is the alloy. "Alloy" material from the technical point of view of the effect of the hardware than the "wire" of the hardware to look beautiful, "wire" hardware becomes more rough. Alloy "is more expensive than the" wire "! Sometimes" shopping "bought a bag, not long before the hardware rust, the surface cortex began to fall off, this is the hardware production did not" seal oil " The reason, there is no oil seal of the metal is very easy to oxidation and rust, "oil seal" after the metal surface material is not easy with the air oxidation. Six, line (the term called "car line"): Bags are generally used outside the 20 # (thicker) of the nylon line, the internal general is the use of 40 # (thinner) nylon line, the liner are generally used in cotton (604 thick, 606 thinner ). Each part of the car line color and fabric color match, visually coordinated. Handbag industry on the "car line" needle density requirements are "one inch seven needles", the general high profile bag in the production will be in strict accordance with this standard. Seven, edge oil: Bag body fabric, handle, edge of the "mouth" are coated with the same color as the above part of the "edge oil" (paint), and some MM may not pay too much attention to this position. (The price of side oil is 17-60 yuan per kilogram of quality.) The effect of good side oil is smooth, with a more "soft" color sense, and fabrics with coordination; almost side oil is feel more than Rough, darker colors! The most important thing about fringe oil is that it is afraid to crack due to seasonal temperature contrast. In the process of making (paint factory), a good frying oil needs to be formulated according to the local climate conditions (chemical raw material composition). General high profile package in the production process of this part of the requirements are very strict, low-end Well, do not say it!
