Difference between Dyeing and Printing Noor Ahmed Raaz CEO & Editor in Cheif Textile Merchandising Blog Lecturer, Department of Textile Engineering Atish Dipankar University of Science & Technology Email: @ Dyeing: Dyeing is one of the major procedures in the textile manufacturing process. Instructions for Immersion Dyeing Follow these guidelines for the ideal amounts* of dye, salt, and soda ash to achieve your desired shade of dye: Very pale: 1/4 to1/2 tsp dye, 1 1/2 cups salt, 1/4 cup soda ash. Light: 1/2 to1 tsp dye, 1 1/2 cups salt, 1/4 cup soda ash. Medium: 1 tbsp dye.
For applying the dye directly onto the ent for stamping, stenciling, Dye painting, Screen Printing, Serti technique on silk and Ikat warp painting on wool or cotton as well as just painting. The following method for using Dharma Fiber Reactive Procion dye is one of the best ways to paint the dye directly onto the fabric. The dye can be thickened with Sodium Alginate Thickener and. The purpose of this book is to demonstrate the wide range of color possibilities available using Greener Shades™ dyes. Each color shown provides its own formula and allows the user to easily choose a palette or suite of colors in which to work for a specific project or choose on a whim. The Greener.
Garment defects is very important issue for the buyers. Generally defects signify lack of quality. During apparel manufacturing process various types of defects occur in garments like faulty zippers, irregular hemming, loose buttons, raw edges, improper button holes, uneven parts, inappropriate trimming, and difference in fabric colours. Use this method to dye fabric or clothing, made of natural fibers one uniform or solid color. Also called Garment Dyeing or Vat Dyeing, this method can also be done in a washing machine. Fiber Reactive Dye is the dye of choice for all cellulose (plant) fibers, like .

Cited by: 2. Control Strategies for Batch Dyeing Processes Control of dyeing processes is a complicated function because of the variability in system parameters, the number of uncontrollable variables and the nonlinear effects of the system dynamics.
We have studied several parametric and non-parametric control approaches for batch dyeing Size: KB. Shade variation may occur selvage to selvage, selvage to center of fabric width or one end of the fabric rolls to another end. Shading or shade variation is considered as one big problem in fabric.
A lot of orders are cancelled because of the shade variation between the batches. After dyeing, oxidation is carried out to restore parent non-ionic dye structure; sulphur dye-cellulose attachment is established through physical forces with dye aggregation occurring in situ.
Shades lack tinctorial brilliance, limiting production to only deep shades like blue, black, khaki and green while brilliant red, orange and yellow are. Mostly continuous dye ranges are designed for dyeing blends of polyester and cotton.
A continuous dye range has been found useful and economically sustainable for dyeing long runs of a given shade. Batch Dyeing: the most popular and common method used for dyeing of textile materials.

Stock dyeing, top dyeing, and tow dyeing occur at various stages of manufacturing, prior to the fibers being spun into yarns. The names refer to the stage at which the fiber is dyed: Stock dyeing. is dyeing raw fibers (stock) before they are aligned, blended, and spun into yarns.
Top dyeing. is dyeing worsted wool fibers (top) after they are. Shade is depth of color. It is a common word in dyeing, printing and finishing unit of a textile mill. It's the physical testing methods of, offline quality control assurance system.
About shade matching: Shade matching depends on the accuracy of the man's eye. It is a visual process for this reason some shade may have different comments. The chapter commences with a discussion of the need for process control in the intermediate machines of a spinning line; the draw frame, comber and speed frame.
Process control in dyeing of textiles. Process control in textile manufacturing provides an important overview of the fundamentals and applications of process control methods.

Cold pad batch dyeing (CPB) is an alternative method of reactive dyeing that uses fewer resources. With CPB there is no need to apply heat during the process, and no salt or humectants are needed. However, the rate of fixation depends on the ambient temperature, so in countries where there is a big difference between summer/winter temperatures, it is good practice to carry out dye fixation in a heat.

Color Match: Visual versus Numerical Pass/Fail Posted on August 8, by NeelimaNarendra Color is a very important aspect of any consumer. Shade is a common word in dyeing, printing and finishing unit of a textile is the physical testing methods of off line quality control assurance system.I have written about the shade matching system in a dyeing lab or lab dip development procedure in one of my blog, I think that will help you to know about the shade matching system.
Shade matching depends on the accuracy of the man. To prepare the batch of fabric for dyeing according to the following criteria – Order sheet (Received from buyer). Dyeing shade (color or white, light or dark).
Machine capacity. Machine available. Type of fabrics (% cotton, PE, PC, CVC). Emergency. To send the grey fabric to the dyeing floor with batch card.
To keep records for every. Dyeing process for different textile materials could be different but its basic idea is same for all. For all types of dyeing pre-treatment is must for removing unwanted materials from textile materials.
Pre-treatment style differs for the shade of dyed materials. Shade may be light or deep. Also these pre-treatment depends on buyer’s. When printing or dyeing fabric, the production run can have color shade issues on a single roll of fabric or from one bolt of fabric to the next.
Shade variances can occur due to a number of issues. The amount of dye stuff, machinery, time, fabric quality, employee error, etc., are a few of the many possible issues that can contribute to color problems.Shade is a common word in dyeing, printing and finishing unit of a textile is the physical testing methods of off line quality control assurance system.I have written about the shade matching system in a dyeing lab or lab dip development procedure in one of my blog, I think that will help you to know about the shade matching system.
