What is the embossing technique used on the 99.99% polyester dyed embossed fabric?

The embossing technique used on a 99.99% polyester dyed embossed fabric can vary depending on the specific manufacturing process and desired design. However, one common method of achieving embossing on polyester fabric is through heat embossing.

Heat embossing involves the use of heat and pressure to create raised patterns or designs on the fabric surface. Here's a general overview of the heat embossing process for polyester fabric:

Fabric Preparation: The polyester fabric is first dyed to achieve the desired color. It undergoes a dyeing process where colorants are applied to the fabric in a dye bath. Once the fabric is dyed, it is typically washed and dried to remove any excess dye and impurities.

Embossing Design: A design or pattern is selected for embossing. This design can be achieved through various methods, such as engraved rollers, screens, or plates. These tools have the desired pattern or design etched onto their surface.

Heat Transfer: The dyed polyester fabric is placed between the embossing tool and a heat source, such as heated rollers or plates. The fabric is subjected to both heat and pressure, which softens the polyester fibers.

Embossing Process: The heated embossing tool is pressed onto the fabric surface with sufficient pressure. The heat and pressure applied cause the softened polyester fibers to conform to the pattern or design on the embossing tool.

Cooling and Setting: After the embossing process, the fabric is cooled down to set the embossed pattern. This cooling step helps the polyester fibers regain their original shape and permanently retain the embossed design.

Finishing: Once the embossing is complete, the fabric may undergo additional finishing processes like washing, drying, and any necessary treatments to enhance its properties, such as softening or adding water repellency.

It's important to note that the specific embossing technique used may vary between manufacturers and can be influenced by factors such as the desired embossed pattern, machinery available, and production scale.
