Para 1414 Aramid Filament Sewing Thread

Para aramid fiber sewing thread 220 celsius degree

Material: aramid filament

Specification: 1000D/3,1500D/3

Aramid fibres consist of yellow filaments of about ten microns in diameter, assembled into threads. There are three main families of polyaramides:

The differents between para aramid and meta aramid:

Para-aramids: used in many fields with high-tech applications, they are mainly known under the brand name Kevlar®, from DuPont, and are used for their mechanical properties.

Meta-aramids: these are mainly recognised for their thermal and chemical characteristics and are known under the brand name Nomex® from DuPont. They are mainly used in the fields of technical textiles and protective clothing.

1. Good mechanical properties

Aramid is a flexible polymer with higher breaking strength than ordinary polyester, cotton, nylon, etc., larger elongation, soft hand feel, and good spinnability. It can be produced into short fibers and filaments of different sizes and lengths. Generally, textile machinery makes different yarn counts into fabrics and non-woven fabrics, which are then finished to meet the requirements of protective clothing in different fields.

2. Excellent flame retardant and heat resistance properties

Aramid has a limiting oxygen index (LOI) greater than 28%, so it will not continue to burn when it leaves the flame. The flame retardant properties of Newstar® meta-aramid are determined by its own chemical structure, so it is a permanent flame retardant fiber that will not reduce or lose its flame retardant properties due to use time and number of washings. Newstar® meta-aramid has good thermal stability, can be used continuously under the condition of 205℃, and can still maintain high strength at high temperatures above 205℃. Newstar® meta-aramid has a high decomposition temperature, and will not melt or drip under high temperature conditions. It will only start to carbonize when the temperature is greater than 370°C.
