Modacrylic Fibres As Flame Retardant

Modacrylic fibres are mainly used as the flame retardant component in household textiles and functional fabrics such as blankets in planes. Cationic dyeable polyester is frequently found in top-fashion sports and leisurewear, while blends of cationic dyeable polyamide with standard polyamide increase the variety of shades that can be obtained on carpets using the differential dyeing method. Work wear made from m-aramid fibres such as Nomex protect fire-fighters in extreme conditions and fireproof overalls made of the same material have long been indispensable in motor racing. The properties of cationic dyeable synthetics are as multifarious as their applications, but such fibres are not easy to dye, requiring specific expertise from textile finishers.


The Modacrylic fibers are produced by polymerizing the components, dissolving the copolymer in acetone, pumping the solution into the column of warm air (dry-spun), and stretching while hot.


Modacrylics are creamy or white and are produced in tow and staple form. Modacrylic fibers are also produced in many different lengths, crimp levels, deniers and they can have various shrinkage potentials.


Flame retardant property of the Modacrylic fibers is its best and the reason for it being so popular with people working areas which are on all time risks from flames. Modacrylics are also commonly used in fur like fabrics, hairpieces, wigs and fleece type fabric. By mixing the various forms of fibers it is easy to create a realistic fur look. The fabrics can then be sheared or embossed to create a closer resemblance to fur. Shirts and trousers worn by electrical lineman are made from Modacrylic fibers.
