Detail Describe How Jeans Are Made

Fabric Purchasing:

While in jeans production, first, you should find out the fabric information of customer approved sample, and then buy the material according to customer order quantity. In terms of selecting denim fabrics, it changes according to the different fitting; for example, skinny jeans are often made of stretch denim fabric, and oversized denim jackets are normally made of none stretch denim material. In China-Jeans, we will select the best fabric for proper design for customers when making custom jeans in our factory.

When cutting the fabric, the cut pieces shall be bundled separately by different size and sent to the sewing workers. During jeans sewing, the front and back pieces are usually sewn separately at the same time. Before further sewing, factory production manager will inspect the semi-finished products. Then we will start to sew the front and back pieces together. After that we will make the waistband, hem, loops and button hole.

The key to good quality jeans is based on good quality washing process. Professional jeans washing technology can make jeans look better. That’s why jeans washing is the most important step in the whole jeans production.
