Parameters

Physical propertiesDescription
CurlWool fibers are more or less wavy and twisted. This ripple is called a "curl". The finer the wool, the more it curls. Merino wool has 30 curls per inch, while coarse wool has one or two.
Rubbing effectRubbing softens wool fibers, especially when wet, thus helping to keep the fabric smooth and soft.
Heat effectLow heat has no effect, but strong heat will weaken the fiber and destroy its color.
Moisture effectWool is the most hygroscopic in nature. It can absorb up to 50 percent of the weight and carry up to 20 percent without feeling soggy. After drying, it will slowly lose moisture, preventing rapid evaporation, thus avoiding giving the user a cold feeling. It absorbs sweat after strenuous exercise and protects the body from sudden changes in temperature.
FeltWool fibers connect and contract when exposed to heat, moisture and pressure. The scaly exterior of the fibers contributes to felting. The fibers soften in weakly alkaline solution due to the expansion of scales at their free edges, and under friction and pressure they interlock again to form felt. The property is used in the manufacture of felt for hats, shoes, floor coverings and sound insulation purposes.
Thermal conductivityWool fibers are poor conductors of heat, so fabrics made from fibers are considered best for winter wear.
ElasticityWool is highly elastic and returns to its original shape when it is wrinkled or moulded and hung.
StrengthStronger than silk. When wet wool loses about 25% of its strength. The longer the fiber, the stronger the yarn.
StretchabilityWool has high elasticity. Stretched about 10 to 30 percent dry and 40 to 50 percent wet, it easily returns to its original size when subjected to pressure when dry.
ShrinkabilityResistance to shrinkage of wool. However, prolonged exposure to moisture can cause shrinkage.

    What is Wool Yarn?

    Wool yarn is a textile yarn that is made from the natural fibers of wool obtained from sheep or other animals such as goats, llamas, and alpacas. Wool fiber has crimp giving elasticity and warmth to the yarn. Wool yarns have insulating properties making knitted or woven fabrics ideal for winter clothing and blankets.

    Wool yarns come in different weights or thicknesses. The weight of a wool yarn is measured in terms of the length in yards per pound. For example, sport weight wool is 168-200 yards per 100 grams while extra bulky wool may only be 40-60 yards per 100 grams. Wool yarns can be knit or woven into many types of fabrics depending on the thickness and properties needed for the end product.

    The Characteristics of Wool Yarn

    Wool yarn has many desirable properties and characteristics:

    • Warmth - The crimp and insulation ability of wool fibers trap air and retain heat. This makes wool fabric ideal for cold weather apparel and blankets.
    • Resilience - Wool has a natural elasticity allowing it to stretch and recover from deformation. This gives wool garments shape retention over time.
    • Absorbency - The wool fiber structure draws moisture vapor away from the body and allows it to evaporate into the atmosphere. This keeps wool dryer than other fibers.
    • Durability - Wool has a relatively high tensile strength and abrasion resistance compared to other natural fibers. It does not easily pill or fray. Properly cared for wool garments can last for years.
    • Flame Resistance - Wool is difficult to ignite and burns slowly. It does not melt or drip when exposed to high heat. This makes it naturally flame retardant.

    How is Wool Yarn Classified?

    Wool yarns can be classified in several ways:

    • By origin - Sheep's wool, merino wool, alpaca wool, etc.
    • By weight - Lace, fingering, sport, DK, worsted, bulky, super bulky.
    • By ply - Single, 2-ply, 3-ply, 4-ply. More plies give more strength and elasticity.
    • By spinning method - Woolen spun, worsted spun. Worsted spinning aligns fibers parallel vs. woolen cross-directions.
    • Blended or not - Wool yarn may be blended with other fibers like nylon, acrylic, silk.
    • Dyed or natural - Wool yarns come in natural sheep colors or can be conventionally dyed.

    So a wool yarn could be "2-ply merino fingering weight dyed wool". This gives knitters and weavers guidance on the properties of that particular yarn.

    The Difference Between Wool Knitting Yarn and Wool Knitted Yarn

    Wool knitting yarn refers to the raw wool yarn used for knitting fabrics on knitting machines or by hand. Wool knitted yarn refers to finished yarn that has already been knitted into a fabric.

    Wool knitting yarns are made from wool fiber that is carded, spun, plied, and wound into balls or skeins. Knitting yarns come in different weights described above. They have not yet been knit into a fabric.

    Wool knitted yarns have gone through the knitting process to create a knitted fabric. The knitted fabric is then unravelled into a finished knitted yarn with loops along the length. Knitted yarns can produce textured hand-knits different than regular knitting yarns.

    So in summary, wool knitting yarns are the raw material while wool knitted yarns are the finished product after knitting that can be knit again.

    The Wool Yarn Manufacturing Process

    Wool yarn production involves several major steps:

    • Shearing- Sheep are shorn to obtain the raw wool fibers. These fibers are greasy with lanolin.
    • Scouring- The wool is scoured in a detergent bath to remove dirt, grease, and impurities.
    • Carding- The washed fibers are run through metal teeth to disentangle and align them into slivers.
    • Combing- Combs are used to further align the fibers and remove short fibers.
    • Drawing- Slivers are attenuated into roving to reduce bulk and even out the mass.
    • Spinning- The roving is spun into yarn by inserting twist to hold the fibers together.
    • Plying- Single yarns may be twisted together into 2-ply or 3-ply yarns for added strength.
    • Winding- Yarns are wound into skeins or balls for storage and shipping.
    • Dyeing- Yarns may be dyed to desired colors. Natural colors are also used.

    The end result is high quality wool yarn ready for knitting or weaving.

    The Performance Indicators of Wool Yarn

    Wool yarn quality is evaluated based on these key metrics:

    • Fiber diameter - Fineness and evenness affect yarn smoothness.
    • Yarn count - Mass in relation to length, e.g. worsted count.
    • Twist level - Twist multiplier indicates tightness and strength.
    • Strength - Measured force to break under tension.
    • Elongation - Ability to stretch before breaking.
    • Elasticity - Recovery from stretching.
    • Evenness - Variations in mass per unit length.
    • Hairiness - Protruding fibers affect appearance.
    • Friction - Dynamic and kinetic friction affect processing.
    • Colorfastness - Resistance of dye to fading or bleeding.

    Meeting industry standards for these metrics ensures the wool yarn has the required properties for its intended use.

    How to Choose Wool Yarn?

    When selecting wool yarn, consider these factors:

    • Intended use - Choose weight and characteristics suitable for the knitted or woven end product.
    • Fiber content - 100% wool or a wool blend? Merino or generic wool?
    • Weight - Lace to bulky depending on desired drape, stitch definition.
    • Ply - More plies increase strength and stretch resistance but decrease loft.
    • Spinning method - Woolen or worsted-spun? Worsted has a smooth, dense feel.
    • Color - Natural sheep colors or conventionally dyed solid, variegated, or heathered colors.
    • Quality metrics - Evaluate thickness, evenness, strength, smoothness, and dye quality.
    • Manufacturer reputation - Established brands known for quality standards.
    • Cost - Prices range considerably so set a budget.
    • Feel - Touch and see if the wool yarn has the right hand and drape.

    The Applications of Wool Yarn

    Wool yarn has many uses thanks to its versatility:

    • Apparel - Wool knits and wovens used for sweaters, hats, gloves, coats, suits.
    • Home furnishings - Wool used for upholstery, blankets, rugs, tapestry.
    • Accessories - Wool craft yarns made into scarves, bags, jewelry.
    • Diapers and sanitary pads - Wool has absorbency and breathability.
    • Military uniforms - Wool's flame resistance, moisture wicking used in uniforms.
    • Industrial felts - Dense, matted wool used for polishing and filtration.
    • Tennis ball covering - The fuzzy coating is made from wool felt.
    • Musical instruments - Wool felt used on piano hammers, guitar picks.
    • Insulation - Non-woven wool mats used for thermal and sound insulation.

    Wool's versatility, comfort, and technical properties make it one of the most widely used textile yarn fibers globally.

    How to Take Care of Wool Yarn Products?

    • Wash gently in cool water with wool-specific detergent. Avoid high agitation.
    • Reshape garments while damp and lay flat to dry. Avoid stretching when wet.
    • Steam press on the backside instead of ironing directly to prevent flattening fibers.
    • Store wool garments properly folded in breathable drawers or boxes. Avoid plastic containers.
    • Use fabric shaver to gently remove surface pilling. Don't pull pills or they will enlarge.
    • Spot clean stains quickly with wool cleaner. Don't rub vigorously.
    • Protect wool from moths by regular cleaning and cedar closets or sachets.
    • Follow any specific care instructions from the garment manufacturer.

    With proper care, wool products will remain beautiful and durable for many years. The key is gentle washing, reshaping, drying, and storage.

    FAQ

    What is superwash wool?

    Superwash wool has been specially treated to reduce felting shrinkage so it can be machine washed and dried.

    What causes wool to felt?

    Agitation, moisture, and heat cause the scales on the wool fibers to interlock forming dense, matted felt fabric.

    Does wool felt easily?

    Merino and other fine wools felt more easily than coarser wools that have larger, more resistant scales.

    Why does wool itch?

    Coarser wool fibers with rough, protruding scales can irritate skin and cause itching. Finer Merino wool is softer.

    Is wool sustainable?

    Wool is a renewable, biodegradable fiber that is naturally flame resistant and long-lasting. This makes it a sustainable textile choice.
