Cotton dyeing

Dyeing The most commonly used processes for imparting color to cotton are piece dyeing and yarn dyeing. In piece dyeing, which is used primarily for fabrics that are to be a solid color, a continuous length of dry cloth is passed full-width through a trough of hot dye solution. The cloth then goes between padded rollers that squeeze in the color evenly and removes the excess liquid. In one variation of this basic method, the fabric, in a rope-like coil, is processed on a reel that passes in and out of a dye beck or vat. Yarn dyeing, which occurs before the cloth is woven or knitted, is used to produce gingham checks, plaids, woven stripes and other special effects. Blue dyed warp yarns, for example, are combined with white filling yarns in denim construction. One of the most commonly used yarn dyeing methods is package dyeing. In this system, yarn is wound on perforated cylinders or packages and placed on vertical spindles in a round dyeing machine. Dye solution is forced alternately from the outside of the packages inward and from the inside out under pressure. Computers are used increasingly in dyeing processes to formulate and match colors with greater speed and accuracy.

Instructions on Basic Fabric Dyeing

All you need is a fabric dyeing or tie-dye starter kit, some cotton sewing fabric, and some household supplies. This book evolved from my days as a fabric dyeing instructor.

Pre-Wash your fabric. Use HOT water and 1/4 cup Synthrapol or Dharma Professional Textile Detergent (PTD) per machine load. This will remove any dirt, grease, or other gunk. Use Enzyme detergents to remove starch. Fabrics treated with permanent press, conditioners, sizing or water proofing, etc are not recommended. This is a very important step. Pre-washing really can make all the difference. We even recommend always pre-washing so called PFD (Prepared For Dyeing) fabrics, as you never know "where they've been". Even fingerprints can cause blotchy dyeing.

5 Easy Steps for DYEING fabric:
1. Gather supplies
2. Mix Dye and hot water in a bowl
3. Add fabric and mix periodically for one hour (+)
4. Drain and rinse fabric
5. Wash and dry fabric in a machine

* Plastic Bowl- large enough to hold 3-4 onesies or a couple T-shirts.
* Mixing Spoon - use one you don’t care about. It will be dyed along with the fabric.
* Clothing for Dyeing - Today I’m dyeing 4 things: some white onesies, a clearance t-shirt from Old Navy (which I’ll sew some sort of applique on top of), and a green onesie that I dyed a year ago but hated the color.
Have an old onesie with milk stains? Or pink onesies that once belonged to your daughter? Dye them for your baby boy!

Knitt Dyeing

At first fabric, required water and required anti creasing agent is added in the dye bath. Then sequestering agent and gluber salt of required amount is added in the dye bath. Then the bath is kept rest for 5 minutes. After that reactive dye of required amount is added in the dye bath. After adding dye in the dye bath, the bath is kept for 30 minutes. During this period exhaustion of dye occurs in the fabric. Then required amount of alkali is added for fixation of dye into the fabric. After adding alkali we will wait for 50 minutes and then we will check the shade. If shade is all right then fabric will be taken for after treatment.

Recipe:

1. Anti creasing agent = 0.3g/L
2. Sequestering agent = 0.5 g/L
3. Glauber salt or NaCl =80 g/L
4. Dye (reactive) = x%
5. Soda ash =5g/L
6. Or caustic soda =1 g/L
7. Acetic acid = 0.75 g/L
8. Soap = 0.25 g/L
9. M: L = 1:10
10. Time =60 min
11. Temperature = 600-1000C

Fibers Dyeing

We can dye your natural fibers into 40 different vivid colors. The cost is $7.85 per clean pound of fibers and $27.00 using our wool or  $29.00 using our 50% wool and 50% mohair blend. These sample colors may not exactly match dyed fibers. 3# Minimum of the same color, clean weight $7.85 per pound. Less than 3#, $15 per clean weight.Beginning with a full fleece, you will learn proper skirting, sorting, and scouring techniques as you prepare the fiber for dyeing. The applying of color to protein fibers before the fibers are spun is easy and fun. First, learn step-by-step how to use the dyes (lanaset) and dye your fibers in a dyepot. A color wheel is used as a reference to figure out how to mix your own colors and create your own dye formulas. A second approach to applying color on fibers is to directly paint dye onto unspun roving; you will also learn how to use painted fibers to create complex, repeatable multi-colored yarns. 73 minutes.

Yarn dyeing

First, you will need to prepare your yarn for dyeing. The yarn I used here is Cascade 220 Wool in white (8505) and cream (8010), and Knit Picks Superwash Wool/Nylon Fingering Weight. You may want to rewind your yarn into larger skeins, but I used my yarn as it came and it worked just fine. Using your waste yarn (I used Caron Simply soft in white) secure your skeins in at least 6 places using a figure-8 style tie. This is a very important step to make sure you don't end up with a tangled mess of yarn at the end of this process. If you’ve wound your yarn into even larger skeins, place ties about every 12 inches. Because my skeins had so much girth to them I did a figure-8 style tie around three sections of yarn.First, you will need to prepare your yarn for dyeing.

Dyeing site of textile

Dyeing is mainly important part of textile.Many kinds of dying in textile.
Dyeing is the process of adding color to textile products like fibers, yarns, and fabrics. Dyeing is normally done in a special solution containing dyes and particular chemical material. After dyeing, dye molecules have uncut Chemical bond with fiber molecules. The temperature and time controlling are two key factors in dyeing. There are mainly two classes of dye, natural and man-made.
For most of the thousands of years in which dyeing has been used by humans to decorate clothing, or fabrics for other uses, the primary source of dye has been nature, with the dyes being extracted from animals or plants. In the last 150 years, humans have produced artificial dyes to achieve a broader range of colors, and to render the dyes more stable to resist washing and general use. Different classes of dyes are used for different types of fiber and at different stages of the textile production process, from loose fibers through yarn and cloth to completed garments.

Industialization of bangladesh

Bangladesh will have within a decade a sizable industrial sector where manufacturing will account for at least 25 per cent of the GDP and at least 20 per cent of the employed workforce. This will mean a considerable rise from the figure of 10 per cent around which the sector's share in GDP and employed population have hovered for most of the past two decades.

A vibrant and dynamic private sector will be the principal actor in Bangladesh's industrial arena. The industrial sector of Bangladesh will be competitive in the liberalized internal market as well as in the external market. The industrial sector of Bangladesh shall have a dominant export orientation.

The goal of external competitiveness implies the pursuit of industrialization in accordance with the dynamic comparative advantage of the economy. Given Bangladesh's resource endowment, the principle of dynamic comparative advantage means production of labor intensive manufactures with skill up-gradation and productivity growth as its cutting edge. This however, does not preclude the possibility of Bangladesh having a niche high-tech industrial sub-sector that may be externally competitive.

Dispersal of small and medium industries will constitute an important element in the industrial policy approach. Industrial development will be sustainable from the point of view of environmental concerns and resource availability.

Industrial Policy 1999 aims at addressing these concerns building on earlier efforts and gains towards industrialization of Bangladesh economy.

INFRASTRUCTURAL FACILITIES AND UTILITY SERVICES IN BANGLADESH
