Typical fancy yarns include snarl, spiral, loop, chenille, slub and nep. Fancy effects can also be created by changing fibre specifications such as type, length, denier, cross-sectional shape, crimp, initial modulus, colour, lustre, affinity for dyes and shrinkage, etc.
Which yarn Below is the weakest?
Wool is the weakest natural fibre while silk is the strongest natural fibre.
What is an example of a novelty yarn?
Novelty yarns are classified according to the single or ply structure: Single yarns are Tweed and Slub Yarns. Ply Yarns are Ratine, Spiral, Knot, Snarl and Boucle. Apart from these, there are many other novelty yarns like Chenille, Flake, metallic and textured yarns.

What are 5 tests that can be run to identify a fiber?
There are different tests which could be used for the identification of the textile fibers such as burning test, microscopic test, solubility test, optical test, density test etc.
What burnt fiber smells like burning hair?
|Silk||Protein Fiber||Burned hair or charred meat|
|Wool||Protein Fiber||Strong odor of hair or feathers|
|Acetate||Manufactured Fiber||Hot vinegar or burning pepper|
Why do some fibers smell like hair when burned?
The smell of burning wool is like burning hair. Acetate is made from cellulose (wood fibers), technically cellulose acetate. Acetate burns readily with a flickering flame that cannot be easily extinguished. … Nylon melts and then burns rapidly if the flame remains on the melted fiber.
What is the difference between Fibre and yarn?
Fibres are obtained from natural sources such as cotton, wool etc. Yarn is obtained by braiding different fibres together.

Yarn can be made from natural or synthetic fibers. The natural cotton fiber and synthetic polyester fiber are two commonly used options. Animal fibers, such as wool, cashmere, silk, and angora are also used in making yarn. Yarn can be separated into two categories based on structure – spun yarn and filament yarn.
