The bags we carry on our backs when we go out are collectively called backpacks. Backpacks are made of a variety of materials,such as leather,plastic, polyester,canvas,nylon,cotton and hemp.Backpacks made of these materials are very popular with consumers.At the same time,in the period of more and more showing personality,various styles such as simplicity,retro,cartoon,etc. also cater to the needs of fashion people to publicize personality from different aspects.Not only in appearance and style,the practicality of backpacks should also withstand the test of consumers.Because consumers are the ultimate players in backpack defect check.
Consumers often encounter the following common defects after purchasing backpacks:
Backpacks made of different fabrics show different defects in the production process.For example,leather backpacks will have surface cracking, wrinkling,peeling,etc.However,non-leather backpacks will have color difference,fading,rough surface,etc. These defects may exist when the raw materials enter the factory or may be caused by subsequent processes.Once it is not found in the backpack defect check,these defective products will be bought by consumers with predictable consequences.
As the face lining of the backpack is composed of three layers,the result of poor sewing is that the backpack seams,shoulder straps or handles are easily separated from the bag body.In appearance,it is more important whether the whole is deformed.If the sewing in the main bag and the side bag is skewed,it is easy to be uneven and the front of the product is skewed,which will directly affect the beauty of the product.On the other hand,backpack defect check often detects backpacks with uneven double lines or blocked stitches and requires factories to rework them.
The logo on the backpack is the symbol of the brand.For importers who want to make their brand popular,the logo on the product must be clear and complete， not easy to fall off,not wrinkled,not faded.
When shoulder straps,handles,pockets,lining,zippers and other accessories are ready,assembly is the last important step.CLI found in backpack defect check that improper assembly will lead to backpack deformation,insufficient loading,high and low shoulders,unsmooth zipper opening and closing and other defects.
Improper operation of each technological link in backpack production may affect backpacks to varying degrees.And these defects are probably because the factory uses inferior raw materials or reduces a certain process,which makes importers to receive complaints from consumers. At the moment,the importer should ask the factory to improve the workmanship and arrange backpack inspection after understanding the reasons for the defects of backpacks,so as to further ensure the quality of backpacks.
CLI suggests that we can start with the causes of defects,analyze the internal logic and take effective solutions.
If the fabric of the backpack is not leather,the backpack defect check needs to carry out gram weight inspection,which is the simplest and most direct judgment method. If it is leather,there are many ways to judge it,such as looking at pores visually and cutting planes.Tactile sense is judged by elasticity and tactility at low temperature.Olfactory, backpack defect check will conduct a combustion experiment on the raw materials and judge according to the odor emitted by combustion.
The assembly of backpacks generally uses adhesive technology and sewing technology to assemble each part according to design.If the workers do not operate properly in the production line,or the glue used is inferior,the formed backpack may have defects such as glue overflow,thread opening,wrinkles,unsmooth zipper, etc. The final process after backpack molding is packaging and packaging inspection can guarantee product safety again.
After analyzing the process on the production line and combining with the structure of the backpack,the backpack defect check is implemented in place.This practice is very effective for improving the quality of backpacks and is convenient for importers to manage their supply chain.This is also the ultimate goal of CLI inspection to provide services to importers,while consumers can also use their backpacks with confidence.
