First, the shoulder strap (arm)
The terms in this part are the same as the common names. The fabric of shoulder straps is generally made of the "fabric" or "ingredients" of the bag body. The structure is two layers, one layer is PVC (there are two kinds of PVC, one is fabric and the other is backing). ) or "hide paper" (hide paper is a kind of kraft paper with some cowhide in it). The connection between the shoulder strap and the bag body is generally "hook" or "ring" hardware, and the two parts of the hardware hook "connection" and "spring" are easy to break, so pay more attention when buying a bag! If it is a "wire" ring, pay more attention to the interface part of the ring. Some circles are die-cast in alloy. Without the interface, this kind of hardware is relieved!
Second, the pocket zipper
Zipper consists of three parts, zipper, slider and tag! Both sides of a zipper are generally made of nylon, and the middle "zipper teeth" are mainly divided into "rubber teeth" and "metal teeth" How to identify a zipper?
First look at whether the "zipper teeth" have fallen off (subtlety);
Second, pull the slider several times to see if the slider and zipper are connected smoothly;
Third, after the zipper is tightened, bend a part of the zipper with greater force, and check whether there are cracks (zipper teeth) while bending, and it is good if there are no cracks;
Fourth, look at the gap between pulling and sliding. If the gap is large, the slider can easily get away from the slider! Because Raqqa is manually fixed on the slider.
Third, the bag body
Some parts of the bag body have different trade terms and common names. The fabric of the bag body is called "main material", and the fabric with arms, pockets and edges is called "ingredient". The front of the bag is called "front", the back is called "back", the left and right sides are called "sides", the outer pocket of the bag is called "outer pocket", the inner pocket is called "middle pocket", the lid of the bag mouth is called "cover", and the buckle connected with the bag body is called "lining". The structure of the bag body is generally three layers, 1, and the outside is fabric; 2. The middle layer is backed with PVC or cardboard, sponge, light glue, pull-back glue, non-woven fabric and foil paper, which can generally be identified by hand feeling. Hard feel is cardboard or thickened PVC, neutral feel is pull back glue, foil paper or soft PVC, and soft feel is light glue, non-woven fabric or sponge. 3. The innermost layer is an inner lining, generally made of nylon (190D, 2 10D, 240D, etc. ), cotton cloth and satin (a fabric with silk characteristics) and so on. The left and right sides of the bag body have the same structure as the bag body. Generally, the bottom of the bag is covered with thick "PVC"!
Fourth, the fabric.
Fabric classification: the quality of natural canvas mainly depends on the "density" of fabric, and people with clothing industry knowledge are good at distinguishing!
Verb (abbreviation for verb) Hardware.
Hardware is generally divided into "wire" and "alloy" according to the material, so how to identify it? Just use a magnet It is iron wire that can be sucked tightly, but alloy that can't be sucked tightly. Hardware made of "alloy" is more beautiful than hardware made of "iron wire" in technological effect, while hardware made of "iron wire" is rougher. Alloy is more expensive than iron wire! Sometimes "shopping" for a bag, it didn't take long for the hardware to rust and the surface cortex began to fall off. This is why there is no "oil seal" in hardware. Hardware without oil sealing is easy to oxidize and rust, and the surface substances of hardware after "oil sealing" are not easy to be oxidized by air. Then what kind of hardware has been sealed with oil? Very simple, just two points:
1, smell it with your nose, a bit like this;
2, touch it with your hand, there is a slight greasy feeling. Hardware with oil seal is more expensive than that without oil seal. Generally, low-grade bags are made of "thread" and there is no "oil seal" hardware!
Generally, the color of hardware is divided into white (terminology is divided into color, color, pearl color, etc. ), bronze (terminology is divided into bronze, bronze, etc. ) and gold (terms are divided into sub-gold and pearl gold, etc. ); The terminology of hardware is mainly used to distinguish the characteristics: "Lai" refers to the general shiny hardware, "Sweep" refers to the hardware with strong luster, that is, the hardware with bright color, "Pearl Lai" refers to the hardware with soft luster, and "Ya" refers to the hardware with hazy luster. No matter what color the hardware is, it will not fade. Some people mistakenly think that the hardware has faded. The most important thing about hardware is that it is afraid of peeling off the surface cortex after rusting. Generally, the hardware with "bronze color" has been sealed with oil. However, due to the production process, it is best not to touch the rain. If there is, dry it with a dry towel, or it will be oxidized and rusted soon!
Six, line (the term is called "car line")
Generally, 20# (thicker) nylon thread is used for the outside of the bag body, 40# (thinner) nylon thread is used for the inside, and cotton thread (thicker 604 and thinner 606) is used for the lining. The color requirements of each part of the car line match the color of the fabric and are visually consistent. Handbag industry requires "one inch and seven stitches" for the stitch density of "sewing thread". Generally, high and medium-grade bags will be made in strict accordance with this standard.
