Friction Calendering
Friction calendering is a textile finishing process that involves the use of heat, pressure, and friction to smooth and compress fabrics, creating a more desirable aesthetic and functional characteristics. This process is commonly used to improve the surface texture and luster of fabrics, as well as to enhance their strength, durability, and wrinkle resistance.
The friction calendering process involves passing a fabric through a series of rollers that apply heat and pressure to the surface of the fabric. The top roller is typically made of steel and covered with a synthetic material, such as nylon, which creates friction as it rotates against the fabric. The bottom roller is usually made of a softer material, such as rubber, which helps to cushion the fabric and prevent damage during the process.
The friction calendering process can be used on a wide range of fabrics, including cotton, polyester, wool, and blends. It can also be used to apply various types of finishes to fabrics, such as water repellency, flame resistance, and antimicrobial properties.
One of the key benefits of friction calendering is that it can produce a high level of consistency in the finished product. The use of heat and pressure helps to smooth out any irregularities in the fabric surface, creating a uniform appearance and texture. This can be especially important in industries where consistent quality is critical, such as automotive upholstery, where the appearance and durability of fabrics can impact customer satisfaction and safety.
Another advantage of friction calendering is that it can be used to create a range of different surface finishes, depending on the type of rollers and pressure used in the process. For example, a high pressure and high-temperature setting can be used to produce a high gloss finish on fabrics, while a lower pressure and lower temperature setting can create a more matte appearance.
Top users of friction calendering include textile manufacturers, garment producers, and home textile companies. Many companies utilize friction calendering as part of their finishing process to enhance the quality and performance of their products.
One example of a company that utilizes friction calendering is Milliken & Company, a global textile manufacturer based in South Carolina. The company offers a range of friction calendered fabrics, including those designed for automotive interiors, outdoor furniture, and bedding.
Another example is Springs Creative, a textile company based in South Carolina that produces fabrics for the apparel, home decor, and craft markets. The company uses friction calendering to create a range of finishes on their fabrics, including a soft, brushed finish for their fleece fabrics.
Overall, friction calendering is an important finishing process in the textile industry, providing a way to improve the aesthetics and functional properties of fabrics. Its versatility and consistency make it a popular choice for a wide range of textile applications.
Friction Calendering
The process of passing fabric through a calender in which a highly polished, usually heated steel bowl rotates at a higher surface speed than the softer (e.g. cotton-filled or paper-filled) bowl against which it works, thus producing a glaze on the face of the fabric that is in contact with the steel bowl.
NOTE:
The friction ratio is the ratio between the peripheral speed of the faster steel bowl and that of the slower bowl and is normally in the range 1?:1 to 3:1.

A bright, shiny finish used on lining twills, sateen silesia, messaline and bind finish cloths. It is achieved when one calendar roller moves at a slightly increased speed over the other roller in the set. Rollers may or may not be heated.
