The basic requirement of clothing technology is that the size and pattern of clothing are not much different. In the production process, lines should be made according to the pattern, and straight lines and curves should not be broken. The purpose of ironing is that some processes of clothing need ironing before they can be modified. For example, after the collar-type placket is finished, the garment should be ironed to ensure its shape and alignment, which is also called positioning version. Every part of the clothing has a craft version with sleeves. There are positioning plates, collar pockets, etc. in front of the positioning plates, all of which have positioning plates. The purpose is to ensure that the garment does not deviate from the pattern as much as possible in the production process. So clothes are divided into market goods and brands. Most of the markets are crude in technology and generally cheap in price. The more important reason is strict quality, good workmanship and expensive sales. It is because the pattern is easy to wear, and the error made by workers is small. Please ask questions about clothing production in the future. You can ask me questions about craftsmanship, men's wear design, etc. Look at my screen name. You should know that I deal with the color of clothes, so I won't reveal it. I will provide after-sales guarantee for this 100 point.
