Novelty yarns include a wide variety of yarns made with unusual features, structure or fiber composition such as slubs, inclusions, metallic or synthetic fibers, laddering and varying thickness introduced during production. Some linens, wools to be woven into tweed, and the uneven filaments of some types of silk are allowed to retain their normal irregularities, producing the characteristic uneven surface of the finished fabric. Man-made fibres, which can be modified during production, are especially adaptable for special effects such as crimping and texturizing.
Novelty yarns are sometimes referred to as complex yarns. A yarn which makes a fabric is not always smooth and uniform. Complex yarns are the uneven yarns which may be thick and thin or have curls, loops, twists and even differently-coloured areas along their length. This look of the yarns are used to add interesting effects in fabrics. In complex ply two or more complex yarns are twisted around each other to form loops, curls and knots to create fancy effects. Many knitting yarns are complex ply yarns which give interesting textures in finished products.
Types of Novelty Yarns
A yarn in which the core has been wrapped by another strand, such as of cotton or nylon around an elastic base as used in commercial socks.
Eyelash yarn is made from a polyester fiber with a furry texture resembling eyelashes. These novelty yarns are made of a thin central ply surrounded by short "hairs". This yarn differs from "fur" type yarn in that it contains evenly-spaced threads at intervals between lengths of bare core thread, whereas fur yarns have an abundance of threads covering the entirety of the core thread. Eyelash yarn comes in a wide range of colors, with the "hairs" sometimes being made of multicolored or metallic fibers..
Bouclé, or looped, yarns are created by loosely looping an effect yarn around a base yarn. They can be made of any type of fiber and are usually composed of three plies, or strands, wrapped around each other. The texture is created by spinning one of the three plies more loosely than the other two. Fiber artists who choose to create projects in bouclé yarn must use extra care because if not handled carefully, the loose strand may split and snag on the knitting needles or crochet hook.
Ribbon is a type of yarn that resembles a ribbon. It can be made from synthetic or natural fibers, such as silk or cotton. Some ribbon yarns are flat, while others are tubular in construction.
Ladder resembles a ladder, with two flat threads representing the two sides of the ladder held together by a strip of material at the center that represents the rungs. The material at the center of ladder yarn can be metallic, beaded, or otherwise adorned. This type of yarn is more often used to create trim or embellishments than to knit or crochet entire garments.
A nub or knot is created by tightly twisting an effect fiber around the base fiber. The nub is most easily identified when the effect and base yarns are of different colors.
A slub or thick spot in a yarn is created by varying the tightness of the twist of the yarn at various intervals.
Corkscrew or spiral
The appearance of corkscrew or spiral yarns is achieved by using yarns of two different fibers and often twisting one under a different tension than the other.
The soft, fuzzy surface of chenille yarns, which resemble pipe cleaners in appearance, can be created in several ways. Most commonly, a fabric is first produced and then cut into narrow strips resembling a yarn. Then, when the fabric is cut, the raw edges become very fuzzy and produce the chenille appearance. Other chenilles are created by trimming a loosely-attached effect fiber to create the fuzzy appearance. Still other chenilles are created by attaching or gluing fibers to the yarn.
Metallic yarns are often classified as fancy yarns and are created by adding a metallic fiber or yarn to the blend. These are not to be confused with actual wire used in jewelry that is sometimes knit or crocheted.
Crepe yarns may be classified as fancy yarns and are created by tightening the twist given to a yarn, resulting in a kinked or looped strand.
