modacrylic is a synthetic copolymer. Modacrylics are soft, strong, ductile, and dimensionally stable. They can be easily dyed, show good press and shape retention, and dry quickly. They have tremendous resistance to chemicals and solvents, not attacked by moths or fungi, and are not allergic. Among its uses are in layers of clothing, outer clothing such as feathers, roller paint covers, carpets, rugs, and work clothes and as a hair in a wig.
The commercial production of modetrylic fiber was initiated in 1949 by Union Carbide Corporation in the United States. Modakrylic and acrylic fibers have the same composition and at one time fall into the same category. In 1960 the Federal Trade Commission decided to separate the two fibers and assign categories to each.
The Federal Trade Commission defines the modacrylic fiber as an artificial fiber in which the fiber-forming agent is a long chain synthetic polymer composed of less than 85%, but at least 35% by weight of the acrylonitrile unit except when the polymer qualifies as rubber.

Produksi
Modakrylic fibers are modified acrylic fibers made from acrylonitrile, but a large number of other polymers are added to make copolymers.
Modacrylic fibers are produced by polymerizing the components, dissolving the copolymer in acetone, pumping the solution into warm air columns (dry-spinning), and stretching during heat.
Modacrylics are creamy or white and are produced in the form of cranes and staples. When viewed from the cross section they have irregular shapes. Modakrylic fibers are also produced in various lengths, wrinkles, deniers and they can have various potential shrinkage.
Modakrilik fiber manufacturers today include Kaneka Corporation in Japan.

Properties
Modakrylic has properties similar to acrylic. However, modacrylics is flame retardant and unburnt. The fibers are difficult to burn and will extinguish themselves. In addition to modakrilik flame retardant properties it has a relatively high durability comparable to wool. Modakrylic fibers have moderate resistance to very low abrasion and ductility.
One of the most interesting properties of the Modacrylic fabric is the arc flash protection, where it has excellent values.
Modacrylics is a bad conductor of heat. The fabric is soft, warm and tough but prone to pilling and webbing. Modacrylic displays high performance when it comes to appearance retention. The fibers are quite resilient and will not tangle. They also have large dimensional stability and high elastic recovery, which gives them the ability to maintain their shape.
Cares
Modacrylic is sensitive to loss of appearance due to improper care; therefore, it is important to know how to care for modacrylic. Modacrylics are resistant to acids, weak alkalis, and organic solvents. These fibers are also resistant to moths, fungi and sunlight. Modakrylic fabrics can be washed by machine using warm water and falling dry at low settings. Modakrylic pieces can also be cleaned dry, however, they should not be steamed and should only fall on cold. Some fabrics can also be cleaned by using the furrier method (a special cleaning process that is not moistened). The fibers are sensitive to heat and will shrink at 250 Â ° F and will become stiff at temperatures above 300 Â ° F.
Usage
Modacrylic is used primarily in applications where environmental resistance or flame retardation is required or required. Modakrylic has the ability to combine flame retardance with relatively low density, which means the protective device is not too heavy (ie shirts and pants worn by electrical lines). The combination of flame retardancy and low density is also useful in furniture, curtains, and outdoor fabrics.
Modacrylic is used by most technical fabric manufacturers, to get comfortable and protective mixtures, to produce PPE.
Modacrylic is also often used on fake fur fabric, toupÃÆ' Â © es, wigs and feather type fabrics. By mixing the various forms of fiber it is easy to create a realistic feather look. The fabrics can then be shorn or knitted to create a closer resemblance to the feathers. The modacrylic heat sensitivity also allows the wigs and haircuts to become curved and hot styles without damage.
Modacrylic is also used on nail fabrics, knit fabrics, and nonwoven fabrics. Other uses of modacrylic include paint rollers, industrial fabrics, stuffed toys and filters.
