1. Overall appearance inspection: The overall appearance must match the signature board, including the front, back, and side dimensions being equal, including each small piece matching the signature board, and the material matching the signature board. Fabrics with straight grains cannot be cut. The zipper should be straight and should not be skewed, high on the left or low on the right or high on the right or low on the left. . The surface should be smooth and not too wrinkled. If the fabric is printed or plaid, the grid of the attached pouch should match the main grid and cannot be misaligned.
2. Fabric inspection: Whether the fabric is drawn, thick threads, slubbed, cut or perforated, whether there is color difference between the front and rear bags, color difference between the left and right parts, color mismatch between the inner and outer bags, and color difference.
3. Points to note when inspecting goods regarding sewing: stitches are blown out, stitches are skipped, stitches are missed, the sewing thread is not straight, bent, and turns, the sewing thread reaches the edge of the fabric, the sewing seam is too small or the seam is too large Large, the color of the sewing thread should match the color of the fabric, but it depends on the customer's specific requirements. Sometimes the customer may require red fabric to be stitched with white thread, which is called contrasting colors, which is rare.
4. Notes for zipper inspection (inspection): The zipper is not smooth, the zipper is damaged or has missing teeth, the zipper tag has fallen off, the zipper tag is leaking, the zipper tag is scratched, oily, rusty, etc. Zipper tags should not have edges, scratches, sharp edges, sharp corners, etc. The zipper tag is oil-sprayed and electroplated. Check the zipper tag according to the defects that are prone to occur in oil-spraying and electroplating.
5. Handle and shoulder strap inspection (inspection): Use about 21LBS (pounds) pulling force, and do not pull it off. If the shoulder strap is a webbing, check whether the webbing is drawn, roving, and whether the surface of the webbing is fluffed. Compare the webbing with reference to the signboard. thickness and density. Check the buckles, rings and buckles connected to the handles or shoulder straps: if they are metal, pay attention to defects that are prone to oil spraying or electroplating; if they are plastic, check whether they have sharp edges, sharp corners, etc. Check whether the rubber buckle is easy to break. Generally, use about 21 LBS (pounds) to pull the lifting ring, buckle, and loop buckle to check whether there is damage or breakage. If it is a buckle, you should hear a crisp 'bang' sound after the buckle is inserted into the buckle. Pull it several times with a pulling force of about 15 LBS (pounds) to check whether it will pull.
6. Inspect the rubber band: Check whether the rubber band is drawn, the rubber strip should not be exposed, the elasticity is equal to the requirements, and whether the sewing is firm.
7. Velcro: Check the adhesion of the Velcro. The Velcro should not be exposed, that is, the upper and lower Velcro should match and cannot be misplaced.
8. Nest nails: In order to hold up the entire bag, rubber plates or rubber rods are usually used to connect the fabrics and fix them with nest nails. Check the "reverse" of the nest nails, also called "flowering". They must be smooth and smooth, and should not crack or be scraped. hand.
9. Check the 'LOGO' silk screen printing or embroidery: the screen printing should be clear, the strokes should be even, and there should be no uneven thickness. Pay attention to the embroidery position, pay attention to the thickness, radian, bend, and thread color of the embroidered letters or patterns, etc., and make sure that the embroidery thread cannot be loose.
10. Shrinking wheat: Check the composition of the product, Part NO, Who Design, Which Country Product. Check Sewing Label Position.
Luggage display
For handbags and luggage used by adults, it is generally not required to test the flammability and effectiveness of the product. There are no specific regulations on the tension of the handles, shoulder straps, and sewing positions, because different styles of handbags and luggage require load-bearing are different. However, the handles and sewing positions must withstand a force of no less than 15LBS (pounds), or a standard tensile force of 21LBS (pounds). Laboratory testing is usually not required, and tensile testing is generally not required unless the customer has special requirements. However, for handbags and hanging bags used by children and infants, higher requirements are put forward, and the flammability and safety of the products are tested. For straps hung on the shoulders or put on the breasts, buckles are required. In the form of Velcro connection or sewing. This belt is pulled with a force of 15LBS (pounds) or 21LBS (pounds). The belt must be separated, otherwise it will get entangled in the erection, resulting in suffocation and life-threatening consequences. For the plastic and metal used on handbags, they must comply with toy safety standards.
Trolley case inspection:
1. Functional test: mainly tests the key accessories on the luggage. For example, whether the angle wheel is strong and flexible, etc.
2. Physical test: It is to test the resistance and weight resistance of the luggage. For example, drop the bag from a certain height to see if it is damaged or deformed, or put a certain weight in the bag and stretch the levers and handles on the bag a certain number of times to see if there is any damage, etc.
3. Chemical testing: Generally refers to whether the materials used in bags can meet environmental protection requirements and are tested according to the standards of each country.This item generally needs to be completed by the national quality inspection department.
Physical tests include:
1. Trolley box running test
Run on a treadmill with a 1/8-inch height obstacle at a speed of 4 kilometers per hour, with a load of 25KG, for 32 kilometers continuously. Check the pull rod wheels. They are obviously worn and function normally.
2. Trolley box vibration test
Unfold the pull rod of the box containing the load-bearing object, and hang the handle of the pull rod in the air behind the vibrator. The vibrator moves up and down at a speed of 20 times per minute. The pull rod should function normally after 500 times.
3. The trolley box landing test (divided into high temperature, low temperature, high temperature 65 degrees, low temperature -15 degrees) with the load at a height of 900mm, and each side was dropped to the ground 5 times. For the trolley surface and the caster surface, the trolley surface was dropped to the ground 5 times. The function was normal and there was no damage.
4. Trolley case down stairs test
After loading, at a step height of 20mm, 25 steps need to be made.
5. Trolley box wheel noise test
It is required to be below 75 decibels, and the ground requirements are the same as those at the airport.
6. Trolley case rolling test
After loading, perform an overall test on the bag in the rolling test machine at -12 degrees, after 4 hours, roll it 50 times (2 times/minute)
7. Trolley box tensile test
Place the tie rod on the stretching machine and simulate expansion back and forth. The maximum retraction time required is 5,000 times and the minimum time is 2,500 times.
8. Swing test of the trolley box’s trolley
The sway of the two sections is 20mm front and back, and the sway of the three sections is 25mm. The above are the basic test requirements for the tie rod. For special customers, special environments need to be used, such as sand tests and figure-8 walking tests.
