Dye-Works Sawa’s dyeing technology is a fusion of traditional techniques, backed by over 90 years of history, and modern innovations that meet contemporary needs. By employing a variety of dyeing methods, we achieve richly colored, high-quality finishes tailored to the characteristics and applications of each fiber.
01/Yarn Dyeing (Pre-Dyeing)
Yarn dyeing (pre-dyeing) is a method in which threads are dyed before being woven into fabric.
Skein yarn dyeing
Skein yarn dyeing is a traditional dyeing technique in which the yarn is prepared in a state known as a “Skein”. In this method, the yarn is bundled together into a circular form called a “Skein” and carefully handled to ensure that the dye penetrates evenly. The hallmark of skein yarn dyeing is that the dye thoroughly permeates even the innermost parts of the yarn, resulting in a deep, rich hue.
Although this technique is labor- and time-intensive, it has been faithfully passed down by many artisans for its ability to achieve a unique texture and expressive color quality. Yarn dyed using skein yarn dyeing boasts a distinctive softness and vibrant coloration when used as a material for woven or knitted products, adding warmth and character to the finished works.
Cheese Dyeing
Cheese dyeing is a method in which yarn is wound onto a cylindrical spool, known as a “cheese,” before being dyed. This process allows the dye to penetrate evenly into the core of the yarn, achieving vibrant and uniform coloration.
During cheese dyeing, the spooled yarn is immersed in dye liquid, and pressure is applied or time is carefully controlled to ensure even absorption throughout the entire spool. This technique is particularly effective for large-scale production, making it ideal for dyeing large quantities of yarn in consistent shades. Additionally, since the dyed yarn can be directly used in subsequent processes, cheese dyeing enhances efficiency and saves time.
Widely used in knitwear, woven textiles, and other fabric applications, this dyeing method is perfect for products requiring consistent quality and uniform color distribution.
02/Piece Dyeing (Post-Dyeing)
“Piece Dyeing (Post-Dyeing)” is a method in which dyeing is carried out after the weaving or knitting process has been completed.
Fabric dyeing involves directly dyeing the woven fabric, allowing for a flexible expression of colors and patterns. This method enables complex patterns and gradients, producing deep hues that are resistant to fading.
Ideal for small-batch production and custom designs, fabric dyeing is widely used in the fashion industry by designers and brands seeking unique color palettes. Additionally, it accommodates seasonal color variations, enabling a swift response to trends and market demands.
Specialty Dyeing
Le Point Dyeing
Le Point Dyeing is a unique technique that uses special dyes to color only the surface of the linen yarn. While similar to indigo dyeing, Le Point Dyeing differs in that it has less fading over time and is less likely to transfer color to other fibers. This method allows for a wide range of color variations and results in a soft, smooth finish.
Linen dyed with Le Point Dyeing develops a charming, natural fade over time, offering an attractive patina that becomes more refined with age. As you continue to use the fabric, you can enjoy its stylish, well-worn look and the gradual transformation of the colors and textures.
Space Dyeing
It is a dyeing method where multiple colors are applied at irregular intervals to a single thread to create kasuri yarn. This technique can express the traditional flavor of Japan.
