What does meta aramid mean?
Meta-aramids—commonly known as Nomex™—are temperature, chemical degradation and abrasion resistant. Meta-aramid is manufactured by wet spinning, the result is a semi-crystalline fiber with the molecular chain oriented along the fiber axis.
What is para aramid material?
Kevlar® Para-Aramid is an aromatic polyamide that is characterized by long rigid crystalline polymer chains. “Para” refers to the specific linkage position of the aromatic rings. Longitudinal alignment of the hydrogen bonds enables high tensile strength and modulus.
What is meta aramid yarn?
Meta-Aramids (such as Nomex®) are highly resistant to temperature, chemical degradation, and abrasion. A meta-aramid fiber is usually manufactured by spinning in a chemical solution, know as wet spinning. The result is a semi-crystalline fiber with its molecular chain partially oriented along the axis of the fiber.
What are characteristics of meta aramid?
Key Features of Nomex® Meta-Aramid: Excellent heat & flame resistance. High chemical resistance. Low thermal shrinkage. Self-extinguishing flame retardant properties.
What is the difference between a polyamide and an aramid?
As nouns the difference between aramids and polyamide is that aramids is (aramid) while polyamide is (chemistry) any of a range of polymers containing amide (or peptide) repeat units; examples include proteins and nylon.
What are characteristics of meta-aramid?
How is para-aramid made?
Spinning. After production of the polymer, the aramid fiber is produced by spinning the dissolved polymer to a solid fiber from a liquid chemical blend. Polymer solvent for spinning PPTA is generally 100% anhydrous sulfuric acid (H2SO4).
Is aramid better than Kevlar?
As explained earlier, Kevlar inherits many of the same benefits that general Aramids do, but it becomes more rigid and durable in general due to its increased bond strength. Some of the biggest advantages for using Kevlar in body armor include: It has a very high melting point. It’s very resistant to low temperature.
How is para aramid made?
What is meta aramid?
Meta aramid is a polyamide having high heat resistance. The most common meta aramid is known as Nomex®. Generally, we manufacture this polymer material via wet spinning. The product of this method is a semi-crystalline fiber material.
What are aramid threads?
Aramid threads are in the category of value-added products in Durak Tekstil’s product portfolio, and they offer technical applicability, quality and safety, which the textile industry seeks, both in production processes and usage afterwards.
Why choose meta-aramid yarns and threads?
When you are searching for a fiber or yarn for specific application requirements, there are many options to choose from. Meta-aramid and para-aramid yarns and threads are two popular choices for heat resistance and superior tensile strength.
What is Durak P-aramid thread?
Durak Tekstil offers Durak Fire Safe P-Aramid® thread, produced from 100% staple fibre para aramid raw material, in two different thicknesses, tex40 and tex60. These threads have a superior heat resistance of 500 °C compared to meta aramids and are not dyeable, and they are used in textiles with their natural straw yellow colours.
