Snarl Yarn:
- Like the loop yarn, the snarl yarn is based around a twisted core.
- In this type of fancy yarn, snarls or twists are observed projecting from the core. ...
- The frequency and size of snarls is controlled by maintaining sinning tension and by the level of twist in the effect yarn.
What are spiral yarns?
SPIRAL YARNS:- The general appearance of a spiral yarn is that of a coarse yarn wound around a fine yarn, giving the effect of a spiral. The thicker yarn is given a slack twist and wound spirally around the fine yarn (sometimes referred to as the CORE YARN), which is given a hard twist .

What is a boucle yarn?
Bouclé yarn is made from first creating loose loops around a core yarn, which can range from tiny circles to large curls that are then secured in place by a binder thread. Bouclé yarns are really fun to spin, so beautiful and are particularly wonderful to use in your weaving.
What is eccentric yarn?
An eccentric yarn is an undulating gimp yarn, often produced by binding an irregular yarn, for example a stripe, slub or knop yarn, in the direction opposite to the initial stage, creating graduated half-circular loops along the compound yarn. It produces an uneven but relatively controllable texture.

What is the difference between bouclé and tweed?
IS BOUCLE THE SAME AS TWEED? No, they actually have slightly different characteristics. Boucle is softer, coarser and has naturally larger slubs, whereas Tweed is a little more durable, sturdy and usually a bit easier to sew.
Can you crochet with boucle yarn?
When crocheting or knitting with a bouclé yarn without discernible loops in the fiber and/or if working on a project with a tighter weave, such as a plushie or wrist warmers, use a hook with a pointier head, or needles with pointier tips, to make it easier to dive through those fluffy stitches.
What is complex yarn?
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. Due to this fancy look of the yarns they are used to add interesting effects in fabrics. Like simple yarns, the complex yarns may also be single or ply.
What is flake yarn?
This novelty yarn is a variation on a slub yarn, in which the flake or slub is created by inserting soft, puffy clumps of roving at intervals held in place by an accompanying binder yarn. As a result, the ending yarn has variations in thickness and softness throughout the length of the finished yarn.
Why fancy yarn is so called?
Fancy yarn, sometimes known as novelty yarn is a yarn that is made with a distinctive irregular profile or a construction that differs from basic single and folded yarns, the objective of which is to enhance the aesthetics of the end product with respect to visual and textural properties.
What is TPI and TM?
The number of turns of twist in one inch of yarn. TM-twist multiple is derived from the TPI and the yarn count and describes the relative twist level in a yarn (TPI = TMvNe).
How do I know what twist my yarn is?
Continuous twist tester: Yarn passed from a rotating jaw end is wrapped on a rotatable drum. Twist is measured by untwisting and twisting a specific length but, after removal of the twist, it is imparted back onto the yarn. By this method an instrument measures the twist per unit length of yarn.
What are the 3 major yarn categories?
There are four different types.Wool Type Fine.Wool Type Medium.Wool Type Long.Wool Type Double – coated.
What is chenille yarn made of?
Chenille yarns are usually made from cotton, wool, rayon, or polyester and are used in fabrics that are soft and velvety.
What is yarn producer?
Yarn producers or spinners buy in natural and/or man-made fibres to make these into yarns of different sizes and characters; regular and fancy yarns. For many years the main spinning systems could be given as woollen, worsted and cotton, and these systems gave rise to the woollen, worsted and cotton industries.
What are some examples of threads with continuous effects?
The following examples belong to the groups of threads with continuous effects: wavy threads, spiral threads, loop threads (boucle, frotte) and chenille threads.
What are the structural parameters of slub yarn?
Key structural parameters associated with slub yarns include the following: slub size with respect to yarn diameter, slub length, and slub spacing or frequency. Typically, slubs are randomly and irregularly spaced along the yarn axis.
How is marl yarn made?
The simplest among the fancy yarns, marl yarn is made by twisting two different-coloured yarns in a doubling process. It differs in texture from normal double yarn. The yarn structure shown in Figure 8.7 clearly shows the alternation of colours, which is the primary effect of marl yarn, as well as demonstrating the plain structure, which is that of an ordinary folded yarn. These yarns are used to make discreet pinstripes in men’s suiting or to produce a subtly and irregularly patterned knitted fabric with a relatively simple fabric construction. They may also be used to provide a Lurex or other metallic yarn with strong support, while at the same time creating a more subtle effect ( Gong & Wright, 2002 ).
What is fancy yarn?
Fancy yarns, also called novelty or effect yarns, represent another category of yarns in which deliberate irregularities, discontinuities and color variations are introduced into the yarn structure with the primary intention being to produce enhanced esthetic and fashionable impressions. 4,7,15 Accordingly, fancy yarns are not necessarily intended for function-focus fibrous products.
How many types of fancy yarn are there?
In general, fancy yarns may be divided into two major categories: 4,7,15 mono-fancy yarns and compound fancy yarns.
What is a snarl yarn?
A snarl yarn is one that displays ‘snarls’ or ‘twists’ projecting from the core. It is produced by a similar method to the loop yarn but uses a lively, high twist yarn and a somewhat greater degree of overfeeding as the effect yarn.
What is loop yarn?
A loop yarn has a core with an effect yarn wrapped around it and overfed to produce a nearly circular projection on its surface . Figure 5 shows the structure of a loop yarn, in this case somewhat simplified by showing the core as two straight bars. In reality, the core, which for a loop yarn always consists of two yarns twisted together, which, can entrap the effect yarn.
What are the components of a yarn?
The three components of the yarn are the core, the effect, and the tie, or binder. The effect yarn has the loops wrapped around a core, or base yarn, and then the third ply, or binder, is wrapped over the effect ply to hold the loops in place. The individual plies could be filament or spun yarns.
What is diamond yarn?
Clearly, a true diamond yarn would show some compression effect upon the thick yarn from the thin ones, an effect which in the interests of clarity is not provided in Figure. This is a yarn that can be very useful to designers looking to create subtle effects of color and texture, particularly in relatively simple fabric structures.
How many yarns are in a loop?
In reality, the core, which for a loop yarn always consists of two yarns twisted together, which, can entrap the effect yarn. As a general rule, four yarns are involved in the construction, of which two forms the core or ground yarns. The effect yarn or yarns are formed with an overfed of about 200% or more.
What is a corkscrew yarn?
A spiral or corkscrew yarn is a plied yarn that displays a characteristic smooth spiraling of one component around the other. The figure below shows the basic structure, which can be produced relatively simply on a doubling frame or under the ring spinning system.
How is diamond yarn made?
A diamond yarn is produced by folding a coarse single yarn or roving with a fine yarn or filament having contrasting color using S-twist, and cabling it with a similar fine yarn using Z twist. Multi-fold or ‘cabled’ yarns may be made by extending and varying this technique, to bring about a wide range of effects.

Alternatively, the slub may be three or four times the thickness of the base yarn , and the increase in thickness may be achieved within a short length of yarn.
What is the fiber structure of yarn made under the air jet spinning method?
Yarns made under the air jet spinning method are of this structure. The yarns produced under the hollow spindle method are also frequently described as fasciated, since the binder is applied to an essentially twistless core of parallel fibers.
What is composite yarn?
Composite Yarns This yarns also termed as compound yarns as well. It consists of at least two threads, one forming the core of the composite yarn, and the other strand forms the sheath component.
