Acrylic Fibers Acrylic fibers, commonly known as acrylic or acrylonitrile fibers, are synthetic fibers made from polyacrylonitrile or PAN. They are versatile, low-cost, and easy to dye, allowing them to mimic natural wool. First commercialized in the 1940s, they soon became widely used in place of expensive wool thanks to their affordability. Let's explore the key properties and applications of this man-made wonder fiber. Chemical Composition Acrylic fibers are polymers produced by polymerizing acrylonitrile monomer units into long chains. Acrylonitrile is a vinyl monomer that contains carbon, hydrogen and nitrogen. In the production process, acrylonitrile is reacted into polyacrylonitrile or PAN, which forms the basis of all. PAN must then undergo further processing steps like stabilization and drying to form the final acrylic fiber. This gives acrylics their desirable qualities like resilience, finishability, warmth and machine-washability. Physical Properties and Benefits Some k...

Geocells Geocells are cellular confinement systems made from polymer sheets or strips that are formed into a honeycomb grid pattern and then flattened for shipment. When expanded on-site, they form three-dimensional mats that can be filled with soil, gravel, or other granular materials to serve as reinforced turf reinforcement structures. Typically made of high-density polyethylene (HDPE) or polypropylene (PP), geocells come in forms ranging from tubular to rectangular to hexagonal shapes. Advantages of Geocells for Erosion and Slope Protection Geocells offer several key advantages compared to conventional erosion control methods like seeding and sodding or riprap placement. As confinement cells, they help prevent soil particles from migrating and allow vegetation to establish deep and strong root systems. The layered cellular structure also improves soil shear strength and bearing capacity. Some major benefits include: - Increased infiltration and retention of rainfall, which assists ...

Acrylic Fibers Acrylic resin are synthetic polymers that were first developed in the 1940s as an inexpensive substitute for wool. Early commercial development began in the late 1940s and early 1950s with the introduction of products like Orlon by DuPont and Acrilan by KoSa. These initial acrylic resin were derived from polyacrylonitrile (PAN), a material manufactured from acrylonitrile and other monomers. PAN-based acrylic resin quickly gained popularity due to their low cost, ability to mimic the look and feel of wool, and ease of care. Through the 1950s and 1960s, manufacturers refined the acrylic fiber production process and developed new acrylic polymers. One notable advance was the introduction of a water-based acrylic fiber production process which reduced manufacturing costs and hazardous waste. New polymer compositions also offered improved properties like greater elasticity, softness, and wrinkle resistance. By the 1970s, acrylic resin had become one of the dominant synthetic ...
