Since the foundation of GLAESER in 1888, the company has been dedicated to the production of fibers from textile waste or textile raw materials. This commitment has increasingly facilitated the trade of raw materials or waste since the 1950s.

The trade department for fibers and textile raw materials was established and developed by one of the two managing directors at that time, Wolfgang Spur.

Initially, this new department focused on the trade of textile waste, which was also processed into fibers in the company’s own processing and shoddy production department. During that period, the main source of production waste was natural fibers such as cotton, wool, and mixtures thereof.

With the rise of the synthetic fiber industry in the 1960s, all types of second-choice fibers (also known as substandard fibers) and special items were increasingly acquired from production plants. The focus shifted towards trading in synthetic fibers, including polyester, acrylic, viscose, polyamide, and polypropylene.

The substandard fibers are collected in the company’s warehouse, often sorted and, if necessary, pressed into new bales. Sorting allows for adapting the qualities to the customers’ requirements. The same principle applies to the traded waste.

Today, GLAESER’s fiber trade involves the sale and trade of both 1st and 2nd choice staple fibers and textile production waste. The company deals with a wide variety of fiber types, such as polyester, viscose, acrylic, polyamide, and polypropylene, available in white, colors, or colored transition sections (different colors mixed). Besides primary fibers (virgin) in various types, they also trade in recycled polyester fibers.

Moreover, the technical area plays a significant role in GLAESER’s fiber trade. The company deals with various para-aramids and meta-aramids, including Preox and Modacryl. In this technical area, GLAESER handles not only virgin fibers but also recycled fibers, particularly the corresponding waste from these technical fibers, such as Para-Aramid, Meta-Aramid, Preox, and Modacryl. They manage not only waste from textile production but also waste generated after the use of aramid products, such as discarded bulletproof vests.
