MC 9463-01

A sustainable process technology that turns cellulose pulp, used textiles, or even old newspapers into new textile fibers without using any harmful chemicals. It is composed of 100% Ioncell-F (lyocell type fibers). The only chemicals used are a non-toxic liquid and water and both are re-circulated in this closed-loop process. In which, the cellulosic raw material (virgin or recycled) is dissolved in an ionic liquid and the dope is spun by dry-jet-wet spinning method into fibers. The mechanical strength of the fibers made from recycled cotton is better than that of the original cotton. These fibers can absorb moisture and are strong even when wet while providing soft handfeel. Their properties are similar to, or in some cases even better than, viscose and Tencel fibers. These fibers are fully biodegradable and exhibit bright luster. In the current pilot-scale production, the material is sold in smaller-sized bales. The fibers spun from recycled textiles keep their original color. Applications are for clothing, interior textiles, and carpets. Continuous filaments can be used in technical applications such as composites.

 

MC 3275-02

A series of lower environmental impact coil and metal zippers with one-way open-end right insert and auto-lock slider in enamel or metal finishing made from recycled materials. The zipper contains about 24% – to 52% recycled PET content, along with other materials, including POM (polyoxymethylene/polyacetal), brass, and zinc. The tape, inner cord, and monofilaments are made from 100% chemically recycled post-consumer PET bottles. In the case of coil zippers, both the zipper chain and slider are made from recycled materials, and since there are no metal components, can be easily broken down and recycled. All zippers are sold by the piece and for the different components (Chain, tape, slider, puller metal teeth) different colors and finishes are available. The material is Oeko-Tex and ECO Mark certified. Applications are appareal and accessories.

 

MC 8954-02

An innovative processing system that converts pre and post-consumer 100% synthetic and synthetic blend textile waste into recycled fiber, yarns, and fabrics. The technology is capable of managing complex blends and stretch fabrics and most of these include recycled polyester (rPET). Finished fabrics come in all different constructions and in a variety of weights ranging from 53 gsm to 216 gsm (2 osy to 6 osy). With a maximum width of approximately 60 in (154 cm), fabrics are piece dyed or dyed with a waterless process to achieve custom colors. Based on what the input is and their desired output, the company will set up a supply chain system to help facilitate the brand’s recycling program. They have already established an end-to-end program in South East Asia. Their system is designed to achieve costs that are competitive with virgin polyester and is highly scalable. Applications include apparel, footwear, accessories, and upholstery.
