Metallic YarnThe yarn which are composed of metals or as a blend of metallic fiber with other fibers.

Metallic fibers are fine drawn filaments of metals which spun and woven.

These yarns express the properties of metals from which they formed.

Source of Material:-o Aluminumo Goldo Silvero Copper

Manufacturing Methods:- There are two manufacturing processes commonly used.

Laminating method Metalizing method

Laminating method:- It is most commonly used method for the production of metallic yarn. In this method Aluminum is sealed between two layers of acetate or polyester.

Coloration of this type of metallic yarn is done by either coloring the metallic filament or by coloring polyester or acetate films.

Metalizing method:- The metal is heated to vaporize. When the metal is vaporize it deposited on the Polyester film at high pressure.

By using this process yarn is:

o Thinnero Flexibleo Durable

Note:

Metallic yarn may Shaved from wires.

Types of metallic yarn on the basis of Yarn Formation:-

Plastic coated metal Metal coated plastic Core completely cover by metal

Plastic coated:- When the yarn is spun inner core is of a synthetic fiber and wrapped with metallic filaments.

Metal coated plastic:-If the metallic yarn is composed of metallic filament

and synthetic fiber with inner core is metal and synthetic filaments are wrapped on the metallic filament.

Core completely cover by metal:- If the metallic yarn is composed of metal and other fibers with core is completely covered with metallic filament and the outer side is of any other yarn.

Types of Metallic Yarn:-Types of metallic yarn are given bellow

M type MH type MX type MHS type ST type

M Type:- M type of metallic yarn is manufactured by metalized process. In which metal is vaporized and deposited on polyester.

Silver and gold are the basic colors of M type metallic yarn.

Uses:-

o Pre dyed textileso Velveto Laceso Embroideryo Accessorieso Interior decorationo Kitchen scrubber

MH Type:- M type metallic yarn twisted with viscose rayon 120D or polyester filament yarn 150D.

MH Type metallic yarn is soft as compared to M Type metallic yarn.

Uses:-

o Sweaters or Knitwear’so Tricotso Embroideryo High fashion clothes

MX Type:- M Type metallic yarn twisted with 30D/1F Nylon yarn X2 ends, 1 end is covered clockwise and other is anti-clock wise.

MX Type metallic yarn has greater tensile strength and graceful color effect.

Uses:-

o Jacquard fabrico Embroideryo Stocking

MHS Type:-

M Type metallic yarn is wrapped on the Viscose Rayon or Nylon

Filament.

Uses:-

Used for Embroidery thread.

ST Type:- Viscose Rayon or Polyester filaments are wrapped on the M Type metallic yarn.

Uses:-

o For machine embroideryo For hand embroidery

Blends:- Metallic Yarn blended with followings for different purposes.

o Polyestero Acetateo Nylono Cottono Silk

o Woolo Viscose Rayon

Uses of Metallic yarn:- Antistatic & antimagnetic waves fabrics, high temperature resistant metal

fabric, high temperature resistant non-woven, sintered filter media, antistatic plastic are also products of metallic fiber

Beaker heat resistant separation material is a range of metal fabric to withstand extreme temperature. They are metal fiber products blended with synthetic fibers for the production of anti-static textile material.

Stainless steel fiber grains for conductive plastics are the most efficient solution to protect against Electromagnetic interference.

Metallic filaments are used for decorative purposes e.g. in Lamps etc. These are also used in upholstery fabric and in textiles. Stainless steel and other metals fibers are also used for communication

purposes in the form of telephone lines and television cable lines. The most common end use for metallic fibers is upholstery fabric and

textiles such as Lame and brocade. These are also used in highly computerized area where such shocks are

expected. They are also protective suits and space suit They are also used in missile nose
