Total blackout curtain fabric production process

As a curtain material with good shading performance, total blackout curtain fabric has a complex and delicate production process involving multiple key links. The following is a detailed introduction to the production process of total blackout curtain fabric:

1. Material selection and pretreatment
Material selection: The material selection of total blackout curtain fabric is crucial, which directly affects the shading effect and durability of the curtain. Commonly used materials include polyester fiber, nylon fiber and certain specially treated natural fibers (such as coated cotton and linen fibers). These materials usually have good shading, wear resistance and wrinkle resistance.

Pretreatment: Before weaving, the raw materials need to undergo a series of pretreatments to ensure that they meet production requirements. For natural fibers such as cotton and linen, shrink-proof treatment and pre-shrinkage treatment are required to eliminate the shrinkage of the fibers during weaving and use, and ensure the dimensional stability of the curtain fabric. For synthetic fibers, due to their good dimensional stability, the pretreatment steps are relatively simple, but they still need to be cleaned and dried to remove impurities and grease on the fiber surface.

2. Weaving and printing and dyeing
Weaving: Weaving is the core link of Total blackout curtain fabric production. Manufacturers select suitable looms for weaving according to design drawings or samples. Different looms differ in weaving speed, warp and weft density, and fabric properties, so they need to be selected according to actual needs. During the weaving process, the tension and density of the yarn need to be strictly controlled to ensure the flatness and shading effect of the curtain fabric.

Printing and dyeing: Printing and dyeing is a key step in giving Total blackout curtain fabric color and pattern. Full blackout curtain fabrics usually use dark or black as the base color to achieve the best shading effect. The printing and dyeing process includes direct printing and dyeing, soaking printing and dyeing, and thermal transfer. Direct printing and dyeing is suitable for the production of a large number of curtain fabrics of the same model, while soaking printing and dyeing can better ensure dye penetration and improve shading performance. Thermal transfer technology is widely used in the production of high-end curtain fabrics due to its delicate printing and dyeing effects and high strength.

During the printing and dyeing process, it is necessary to strictly control the concentration, temperature and time of the dye to ensure uniform dyeing and strong color fastness. At the same time, the curtain fabric after printing and dyeing needs to be fully washed and dried to remove excess dyes and auxiliaries to ensure the environmental performance of the curtain fabric.

3. Finishing and shaping
Finishing: After printing and dyeing, the Total blackout curtain fabric needs to be finished. Finishing includes finishing, drying, cutting and other links. The main purpose of finishing is to eliminate some problems left on the cloth after printing and dyeing, such as looseness, pilling, dead hair, etc. Drying is to remove moisture from the curtain fabric to a certain degree of dryness. Cutting is to cut the curtain fabric into appropriate size and shape according to actual needs.

Shaping: Shaping is an important step to maintain the shape and stability of the Total blackout curtain fabric. Common shaping methods include wet heat shaping and hot roller shaping. During the shaping process, the temperature and time need to be scientifically controlled to ensure that the curtain fabric can be quickly shaped after heating and maintain its original size and shape. The shaped curtain fabric not only has a better shading effect, but is also not easy to deform or shrink during use.
