Yarn Fibers
Murray Fabrics knits tubing out of a wide variety of yarns to fit each customer's individual needs. The different fibers can be used for corrosive situations whether you are dealing with chemicals, extreme temperatures, or fire safety, as well as simple filtration.
Knit tubing can be made out of the following yarn fibers:
Below is a chart to help determine which fibers are best for your needs. However, for expert advice call us at 216-881-4041 to talk to one of our fiber specialists.
Fabric Type |
Characteristics |
|
| Polypropylene | Offers good tensile strength and abrasion resistance. They perform well in organic and mineral acids, solvents and alkalies. Polypropylene is attacked by nitric and chlorosulphonic acids, sodium and potassium hydroxide at high temperatures and concentrations. pH range: 2-12 Temperature: up to 190° F |
|
| Polyester | Offers good resistance to most acids, oxidizing agents and organic solvents. Concentrated sulfuric and nitric acids are the exception. Polyesters are dissolved by alkalies at high concentrations. pH range: 2-9 Temperature: up to 325° F |
|
| Nylon | Good tensile strength and alkali resistance but is degraded by mineral acids and oxidizing agents. This reaction is accelerated at high concentrations and temperatures. pH range: 2-8 Temperature: up to 250° F |
|
| Cotton | Good abrasion resistance and mechanical strength. It is, however, subject to rot, mildew and shrinkage. pH range: 3-10 Temperature: up to 225° F |
|
| Acrylic | The resistance of acrylic fibers is excellent in organic solvents, good in oxidizing agents, minerals and organic acids and fair in alkali. Will dissolve in sulfuric acid concentrations. pH range: 4-5 *Subject to other variables Temperature: 260 to 280°F / 125 to 135°C |
|
| Nomex* | Resist attack by mild acids, mild alkalies and most hydrocarbons. Resistance to sulfur oxides above the acid dew point at temperatures above 300°F is better than polyester. Flex resistance is excellent. pH range: 2 - 12 Temperature: up to 425°F |
|
| Kevlar* | Kevlar (aramid yarn) is chemically stable under a wide variety of exposure conditions; however, certain strong acids and bases can cause degradation, particularly over long periods of time and at elevated temperatures. pH range: 5-7 |
|
