How To Dye Wool: Greatest Dyes & Procedures For Dyeing Cloth Yarns & Fabrics

Before diving into the center of the matter I’ll go over some fundamentals of wool.

Wool has been one of the earliest fibers known to mankind. We mainly find the cloth from lambs, but from goats, alpacas, as well as camels. Wool is primarily produced in Australia, East Europe, Nz, as well as China.

How to dye wool exterior is primarily made up of superimposing protein measurements. Wool’s external surface repels liquid, so it stays warm including in wet weather. An innermost wall, from the other side, absorbs liquid & amusingly, this could consume so even which wool stays reasonably clean even though it absorbs nearly double its mass. Wool, based on internal moisture, is indeed normally flame retardant.

Furthermore, wool seems to be the already natural fiber that displays warm air of soaking, such that it creates heat once wet.

Because the method is so similar, teaching how and when to color wool would also allow you to color other protein fibers. Please remember that if a dyeing procedure appears to be too difficult for you, guys could always opt for the finest paint for garments to make things simpler for themselves.

How To Dye Wool Or Even Other Protein Fiber Dyeing

Wool could be colored in almost the same way that other animal fibers such as organza, camel’s hair, alpaca, as well as cashmere will be. This is due to the fact that all animal fibers are made up of protein.

To construct proteins twenty main amino acids are incorporated in various ways. Cellulose has been made from recurring units of carbohydrates; glucose is synthetically easier than wool. Once compared with wool, distinct dyes, as well as chemicals, could indeed form bonds of cellulose in many more ways. However, dyeing wool yarn protein fibers can be done in a variety of ways & with a variety of substances.

Important Factors To Consider Before Dying Wool

All animal fibers are extremely sensitive to alkali, as well as high pH levels. As a result, caustic soda, which is crucial in cloth dyeing, must be completely avoided throughout wool dyeing.

Most cotton dyeing wool yarn recipes include citric acid, acetic acid, as well as white vinegar.

Wool dyeing wool yarn  necessitates the use of heat. It is possible to accomplish this by,

Using a simmer as well as a heating system to warm the dyebath, which contains wool, colorings, as well as chemicals.

Directly attaching the dye, followed by steaming to set a dye.

A dye pot has been required for wool coloring for such reasons. But, let us go over it in depth.

Choosing A Dye Pot

When choosing dye pots besides wool dyeing, users must be more careful than with other synthetic dyes techniques. The significance of the accompanying main factors should not be underestimated.

The Dye Pot’s Material

Aluminum dye pots can not be used because the aluminum reacts also with acid, which is used as a supplementary chemical in sheepskin dyeing. However, aluminum could be used mostly during the steaming process.

Because stainless steel doesn’t really react to chemicals, that is a suitable choice for a dye pot. The issue is if ions are not thoroughly dissolved in water throughout dyeing, stainless steel might well be damaged.

Steel pots (canning) of enamel covers are another option that is less costly. The issue is that enamel would be easily chipped. The remedy though is which is simple to repair. To replace broken enamel chips, thermal-resistant enamel coatings could be used.

The Dye Pot’s Size

To avoid material cramping as well as uneven coloring, a large enough dye pot should be used. Both for smooth or even dying, the dye pot wherein the dyeing wool yarn substance could really freely move in liquid is recommended. Unless you’re using a quite small amount of dye, use a pot which can retain at least 3 gallons with liquor or even more.

Simply utilize quart-sized containers (canning). Those who also meet the non-aluminum component necessity.  A liquid bath could be used to heat a pot. Position the containers throughout the water bath as well as cover them. Check the heat in an external bath & keep this at the desired temperature.

Miscellaneous Tools


The thermometer is required to keep track of heat as well as retain it perfectly. A thermometer can be purchased from a dye provider, a synthetic supplier, or even a regional home brewing provider. A thermometer must have a temperature range of 0oC-100oC (32oF-212oF).

  • Measurement Spoons & Cups
  • Pipettes (graduated cylinders)
  • Stirrer
  • Lifters of jars
  • Handcuffs

Choosing The Dyestuff

Dye Acid

This is a more commonly used dye for coloring wool & contains a wide variety of dyes. Food colors, Pre-metalized colors, Acid dyes for yarn colors, Washfast Acid colors, Acid Leveling colors, & 1-shot colors are among the acid dyes accessible.

Reactive Fiber Dyes

When acid dyes for wool, you could also use fiber reactive dyes such as Procion MX, Cibacron F, & Drimarene K

Natural Color Dyes

The majority of organic dyes are easily implemented into protein fibers, primarily for coloring wool dyes. Some could require a mordant, typically copper, aluminum, lead, as well as iron, however, the issue is that they’ll be quite toxic than synthesized dyestuffs.

Dyes From Lana Cet

Lana set dyes to seem to be the most long-lasting and wash-resistant dyes accessible in the United States now for wool dyes staining. Lana set coloring is made up of both fiber reactive pigments & acid dyes for wool dyes that are designed for fleece. Lana set dyes, like many wool dyes, can be washed without falling away in warm water. These were frequently hard to locate in certain countries.

Dyes For Vinyl Sulfone

Vinyl sulfone pigments, also known as the Remazol dyes, were a type of fiber functional dye that is commonly used on silk. Their implementation process like that of Procion MX colors is similar to that of true fiber reactive pigments, rather than acidic dyes for wool. It’s worth noting that they’re marketed as:

  • Dharma Trading Corporation’s Vinyl Sulfonate
  • Prochem Fluid Reactive Dyes
  • Other companies’ Remazol dyes

Tax On Dyes

Vat dyes (including indigo) can also be used to dye wool as well as various protein fibers. However, high pH levels should be avoided as they may damage the wool.

Dyes For Every Purpose

Because acid dyes for wool pigments are present in their combination, these dyes were also suitable for coloring protein fibers. The final color achieved could differ slightly from the perception, or the prices are higher because a large quantity of dye would be needed.

What Really Is The Finest Dye For Dying Wool?

We tried out a few different dyes designed for colouring protein fibres like wool. By terms of brilliance, fastness, and shade range, the below dyes fared best.

When It Comes To Level Dyeing, This Is The Best Option.

2.Rit Liquid Dye (All-purpose)

You can use our dye colors mixing instructions to acquire the shade you want. Just sure to follow the personality first and make any necessary adjustments. Nevertheless, we must tell you that getting perfect hue and texture on the first try is nearly impossible.

How To Dye Wool Fabric

Wool dyeing does not allow for the use of interchangeable dyes. Most require an acetic base such as vinegar, citric, CH3COONa, and (NH4)2SO4, and not always in the very same quantity, while some  Albegal SET, require salt, and Na2SO4.

Some colourants require a little lower pH than others; if you choose a pH which is too high or too low in your colouring, you will reduce dyeing wool fabric efficiency. Choose a wool-dyeing method that includes the precise type of dye after you’ve chosen your dye.

Let’s take a look at a method for level dying wool and also the wool element of a fibre blend.

An aqueous solution of organic dyes with such a chemical reagent that combines with the wool fibre under set circumstances by nucleophilic condensation reactions is required for this discharge dyeing wool fabric technique.

The dying temperatures vary from 95 to 106 ° C. Fast dyeing wool fabric in one stage is required. Dye fixing does not necessitate the use of acid dyes for wool or acid dyes for yarn giving agents.

Whenever the exact adiabatic state for dye fixing is obtained at dyeing temperature, gradual administration of sulphuric acid dyes for yarn towards the heated dye bath over 10-45 minutes was required to keep pH values around 2-3.

How To Dye Wool Techniques Works 

Wool dyeing can be done in a variety of ways, including hand dying yarn. Wool is usually dyed in packages or hanks.

The following is a Hank version of a standard wool dying yarn coloring technique. Short-Skein (Hank) dying is the title of the technique.

In a dye bath with a large jar, relatively dense dying yarn in skein and coils are laid more than a rung and soaked. The best color penetration & softer fabric are the key benefits of this approach. This procedure is mostly used to dye bulky acrylics and woolen dying yarn.

All synthetic dyes appear to be coloured because they absorb light at specific wavelengths. The pigments, unlike a dye, are normally insoluble and have no affinity for the substrate. To make a pigment using water, many pigments can be precipitated with an innocuous salt.

Dyeing Of Other Woolen And Animal Fibres

Utilizing similar dyes, a lot of different fibres can be colored in the same way. This category includes fur from numerous species, as well as alpaca, Cashmere, mohair, or angora. Some will not be as affected by the hue as others.

Superwash wool is simple to colour. Because the exterior layer of each fibre is damaged by dye molecules chlorination, and may freely penetrate the wool fibre interior, the fibres absorb dye more effectively than pure wool. To prevent felting or shrinking, the leftover scales are retained in the fibre using a coating (resin).

Smartwool is made in the same way, but with a different chemical in place of the chlorine dioxide step. It is still unknown if it can be colored as simply as superwash wool.

Angora does have the fur of an angora bunny. It seems to generate milder colours than cotton with the same amount of dye.

An Angora goat’s fur, Cotton yarn, can be dyed using a similar procedure and the same colours. It absorbs dyes really well. You must not boil it during dying, but rather keep it at a significantly reduced temperature for roughly an hour to allow the dye to infiltrate the fibre easily. A temp of not upwards of 82 degrees C is recommended in most cases.

Woolen Shrinkage

We’ve all heard of shrinkage. Since they are chemical solvents, smartwool or superwash wool, among other things, need not shrink. Wool fibres, on the other hand, do not decrease in length. However, when heat is applied and pressure in liquid, the fibres become increasingly entangled, with the scales that really are present on the fibre molecules acting as ratcheting teeth.

If you want to avoid shrinking and felting, you must be mindful not to disturb the wool while it’s in the heated liquor. To minimise uneven dyeing, stir your dye bath regularly with cellulose fibres, but the natural dyes & surfactants help wool color uniformly without agitation.

Be aware of rapid temperature changes. Simply gradually increase and decrease the temperature on your cotton. You don’t really want your fleece to move about.

Whenever dyeing wool that will be used for intentional felting, utilize Lanaset dyes, which seem to be washfast. Once felt, less washfast hues can leak.

Final Thoughts

We didn’t intend for this essay to be any lengthier than it needed to be. They also attempted to cover various elements of wool dyeing.
