Garments dyeing:

The garments dyeing process is a new technology for us but it is actually using in the European countries for the last 70 years. It is the process of dyeing fully fashioned garments subsequent to manufacturing, as opposed to the conventional method of manufacturing garments from pre-dyed fabrics. At first, this technology applied on woolen and silk garments but now it is applied on polyester, nylon, acrylic and also extensively on cotton garments. The popularity of garment dyeing is increasing in France, Italy, Spain, Germany, Canada, Turkey, Israel, South Africa, Japan, USA and UK, etc. counties.

In garment dyeing, fully fashioned garments such as pants, sweaters, shirts, and skirts are dyed after manufacturing is completed. Most garments are made of cotton or cotton-rich blends which may contain other fibers such as wool, nylon, silk, acrylic, or polyester as a minor component in the blend. Traditionally, garments are manufactured from pre-dyed fabrics before cutting and sewing. Garment dyeing has been gaining importance and popularity due to cost savings and fashion trends in recent years and will continue to grow in the future.
