What is the yarn called when two different colored yarns are twisted together?

flock or flake yarn. loosely twisted yarns with fibers of another color (or other colors) inserted in the structure. spiral or corkscrew yarns. two plies of different sizes of yarns are twisted together. nub or slash yarns.

What is twisted yarn called?

Spun yarn. Spun yarn is made by twisting staple fibres together to make a cohesive thread, or “single.” Twisting fibres into yarn in the process called spinning can be dated back to the Upper Paleolithic, and yarn spinning was one of the first processes to be industrialized.

What is multi twist yarn?

Multi-twist yarns are those that feature a constant count but have different levels inside yarns. These twist levels create variations in the yarn’s dye intake thus creating a special fabric appearance.

What is twisting yarn?

twisting, in yarn and rope production, process that binds fibres or yarns together in a continuous strand, accomplished in spinning or playing operations. … The number of turns per unit of length in a yarn affects the appearance and durability of fabric made from that yarn.

When two-ply yarns twisted together it is called?

Plied yarns are produced by twisting together two or more singles yarns. Generally, during plying, the yarns are twisted in the direction opposite to the singles-yarn twist to give a torque-balanced yarn. … Yarns with special effects on their surfaces are known as novelty yarns.

What are the two types of yarn twist?

The twist direction is the tilting direction of the fibres in a single yarn or of the single yarn in a ply yarn. It is divided into two types: Z-twist and S-twist.

What is flock yarn?

INTRODUCTION TO FLOCKED YARN

Flocked yarn has a velvet appearance, with soft touch, high comfort, excellent moisture management and is able to absorb and reduce friction. … Main application field of flocked yarn is the automotive market. Textiles woven with flocked yarn are used as covers of car seats.

What is a monofilament yarn?

Monofilament yarn, as evident by its name, consist of a single solid filament. Monofilament yarns are usually circular and solid in cross section. The shape of the filament can be altered to produce noncircular and/or hollow filaments. The diameter4 range of monofilament yarns is 100–2000 μm.

What is multiple yarn?

A multifilament yarn is composed of a bundle of very thin, infinitely long threads. The threads are generally referred to as filaments. These yarns are generally spun on vertical machines with filaments extruded out of the spinnerets and air-cooled before getting wound onto spools.

What is S twist and Z twist in yarn?

S-twist yarn is a yarn spun counter-clockwise and is normally used to create right-handed twill, while Z-twist yarn is used for left-handed twill. By opposing the direction of the yarn and the direction of the twill, the finished material is softer than fabric created with a corresponding yarn and twill weave.

What is doubling and twisting?

The method of twisting two or more single yarns is called doubling or folding or ply twisting. Such yarns are designated as doubled yarn, folded yarn or plied yarn and the machines intended for the purpose are called doublers, ply-twisters or two-for-one (TFO) twisters.

What is TM in yarn?

The twist multiplier (TM) plays a large part in assigning the stiffness or “feel” of a yarn. It also affects strength, light refraction, and many other qualities. In general: Low TM = softer yarn. High TM = stiffer yarn.

What is staple yarn?

Staple yarns, also called spun yarns, are made of fibers that come in short discrete lengths. All natural fibers except silk are staple fibers. Filament yarns are collections of long continuous filament fibers.

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.

How is textured yarn different from flat filament yarn?

Texturing is the main method to produce the bulked filament yarns. A textured yarn is made by introducing durable crimps, coils, and loops along the length of the filaments. As textured yarns have an increased volume, the air and vapour permeability of fabrics made from them is higher than that from flat yarns.
