What is Nomex Fiber and Yarn. Complete Description.

Complete description of Nomex Fiber, Nomex Yarn and Nomex Fabric and its end use.

Nomex is known as one of the most versatile fibers in the world. Its long list of uses includes everything from personal protective equipment to fire-retardant insulation, to food packaging—and it even has medical benefits.

Nomex fiber is composed of the same material as fire protection suits used by firefighters. It’s incredibly tough, but also highly flame-resistant and resists decay when exposed to oxygen. It’s often used for making high-end garments like racing suits and motorcycle racing gear, as well as upholstery and other textile products.

Nomex fiber is a synthetic fiber made from coal tar, one of the byproducts of coal-fired power plants. Nomex fabric is a combination of Nomex fiber and flax or cotton thread that can be used for various textile applications from protective clothing to sailcloth.

Nomex fiber, or polytetrafluoroethylene, is a type of fluorine-containing polymer. It is a single-layer resin that can be used for several different applications including cooking utensils, food wrap, and even in the construction industry. Nomex yarn is made from nomex fibers and can be used by medical technicians who are involved with invasive procedures on their patients.

End Uses of Nomex Fabric

Nomex Fabric is with excellent tear and abrasion resistance, Nomex offers advanced fire protection for industrial environments.
Nomex fabric is used in high-performance environments, such as avionics, electronics and power systems. Its excellent properties make it ideal for electricity generation and transmission.
Nomex is one of the most commonly used fire-prevention materials. It is often used in construction sites to prevent oil fires, as in diesel engine exhaust fumes. Nomex is also used in aircraft and often as a fire retardant in garments such as flight suits and hoses.

Following are the industries commonly using Nomex Fabric.

  1. Textile coating, fiber and heat resistant.
  2. Electric arc welding fabric (electrostatic arc erosion).
  3. Used for electric arc welding on carbon steel, alloy steel, aluminum alloys and other metals.
  4. General purpose fabric suitable for general purpose applications.
  5. Used for high temperature oil refineries and petroleum refinery plants.
  6. Possibly used in hydrogen chloride production process.
  7. Used in natural gas liquefaction equipment.
  8. Used as a container filler prior to sealing with Nomex

Major fabric faults in weaving fabric

The fabric industry is a very large and important part of the clothing industry. The production of fabric starts with the manufacturing of yarns. There are many different types of fabrics, but they all have one thing in common: they are woven from yarns. Fabrics can be made from natural or synthetic fibers, or a combination of both. They can also be woven or knitted. The type determines the type of fabric and quality of fiber used to make it and the weave it is made in. Fabrics can be used for many purposes, such as clothing, upholstery, drapery, bedding and other household items such as curtains and tablecloths.

Grey fabric is a type of fabric that is not dyed. This means that the natural white color is preserved in the fabric and it will have no color variation. The main difference between white and grey fabrics is that grey fabrics can be used for multiple purposes such as making clothes, curtains, and bed sheets. Fabric faults are the most common problem that a fabric can have. Fabric faults can occur as a result of many factors. Some of these factors include the quality of the fabric, how it was handled, and how it was dyed. Fabric faults are a major concern for any fashion designer. The fabric may not be perfect, but these faults can make the garment look shabby and cheap.

The main types of fabric faults are:
Miss Pick
Starting Mark
Coarse Pick
Coarse End
Selvedge Defect
Lose End
Sizing Stain
Increase Density

What is Miss Pick in Fabric?

Miss pick: Miss pick refers to a defect in which one or more weft yarns were missed during weaving process. Selvedge defect: This defect occurs when there are missing weft yarns at one or both edge of cloth due to warp thread. or Miss picks happen when the yarn is not properly picked up by the loom and is then woven into the fabric in a way that leaves an open space in between two rows of weft yarns.

What is a Starting Mark in Fabric

A starting mark is when a weft thread starts from an incorrect position on the warp beam. or
Starting marks are when there is an indentation on one side of the fabric caused by a starting shuttle being used to start weaving at one end instead of both ends.

What are floats in Fabric?

Floats are sections of yarn that hang off the selvedge of a fabric, which are created when there’s not enough space on either side of the fabric to keep them in place during weaving.

What are Cracks in Fabric

Cracks are caused by a variety of issues, including too much tension during weaving or improper drying after being washed.

What is Coarse Pick in Fabric

coarse pick is a result of the machine that was used to weave or knit the fabric. It can cause threads to be picked up from other parts of the fabric and woven into it.

What is Coarse End in Fabric

A coarse end occurs when the yarn, which was woven into the fabric, has not been properly cut off from the loom. This can cause problems such as fraying or unraveling of threads on the edge of cloth.

What is Selvedge Defect in Fabric?

Selvedge defect is a result of poor-quality control during weaving or knitting process. It occurs when one side of a fabric is not trimmed properly and threads are left on one side.

What is Lose End in Fabric

Lose end is caused by machine malfunctioning during weaving or knitting process, which leaves some threads loose on one side of a cut piece.

What is sizing Stain in Fabric

A sizing stain is a type of fabric fault where the fabric is treated with a sizing agent before weaving. Either too much or too little sizing agent can cause it. The most common way to identify a sizing stain is by looking at the back of the fabric. If there are small, white spots on the back, then it is likely that there was too much sizing agent applied to the fabric and it will shrink more than other fabrics in the wash. If there are large, white spots on the back, then it is likely that there was not enough sizing agent applied to the fabric and it will not shrink as much as other fabrics in a washing machine.

What is Increase Density in Fabric

Increase Density. This problem indicates that fabric has more picks or ends at some certain piece of fabric than the required standards.

What is difference between Viscose, Modal and Lyocell Fiber

Viscose, Modal and Lyocell fibers are made from tree or plant fibers after cellulosic process. Mainly soyabean, bamboo or even cotton plants are used to make this fiber. Some other plants are also used to produce Viscose, Modal and Lyocell. These fibers are also called Cellulose fibers.

Now question arises what is the difference between Viscose and Modal or what is the difference between Viscose and Lyocell or What is the difference between Modal and Lyocell.
Its answer is quite simple. which we can describe you with the example of a laptop. Like we go to the shop and ask the shopkeeper about its specification. Shopkeeper told us that this laptop is 1st generation other one with better performance is 2nd generation and this one is its 3rd generation and best of all.
Same is the case with Viscose, Modal and Lyocell.
Difference between Viscose fiber, Modal fiber and Lyocell fiber

  1. Viscose is the first generation out of these three.
  2. Modal is the 2nd generation with better quality and strength.
  3. Lyocell is the 3rd and best among these three.

Hope you have now better understanding about the difference between Viscose, Modal and Lyocell.
