Modacrylic is lightweight, soft, and warm, with a wool-like feel. It does very well and has excellent colourfastness. It is resilient, retains its shape, and resists shrinkage and wrinkles. Modacrylic has recently been used in clothing as a less expensive alternative to cashmere, due to the similar feeling of the materials. Modacrylic is resistant to moths, oils, and chemicals, and is very resistant to deterioration from sunlight exposure.

Modacrylic and acrylic fibers are similar in composition and at one time were in the same category, Modacrylic fibers are modified acrylic fibers made from acrylonitriles.

Properties

 

  • Modacrylic has properties that are similar to an acrylic. However, modacrylics are flame retardant and do not combust. The fibers are difficult to ignite and will self-extinguish. In addition to a modacrylic’s flame retardant properties, it has a relatively high durability that is comparable to wool. Modacrylic fibers have a moderate resistance to abrasion and a very low tenacity.
  • Modacrylics are poor conductors of heat. The fabrics are soft, warm and resilient. Modacrylics display high performance when it comes to appearance retention. The fibers are quite resilient and will not wrinkle. They also have great dimensional stability and high elastic recovery, which gives them the ability to hold their shape
End Uses
  • Modacrylics are used primarily in applications where environmental resistance or flame retardancy is necessary or required. Modacrylics have the ability to combine flame retardancy with a relatively low density, meaning protective gear is not uncomfortably heavy (i.e. shirts and trousers worn by electrical linemen). The combination of flame retardancy and low density is also useful in furnishings, draperies, and outdoor fabrics

 

Modacrylics are also commonly used in furlike 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. The heat-sensitivity of modacrylic also allows wigs and hairpiece to be curled and heat styled without damage. Modacrylics are also used in fleece, knit-pile fabric backings fabrics and industrial fabrics.
