Birla Cellulose: joint patent for high tenacity lyocell

A joint patent application has been filed by Birla Cellulose, the pulp and fiber business of the Aditya Birla Group, Mumbai/India, and Nanollose Ltd., Nedlands/Australia, for a high tenacity lyocell fiber made from bacterial cellulose.
The patent application represents a major advancement over Nanollose’s previous viscose versions of nullarbor and nufolium fibers. Using the lyocell process, nullarbor fiber has been produced that is finer than silk and significantly stronger than conventional lyocell that is traditionally based on wood pulp.
Lyocell is a form of rayon, made using a closed loop process with low demand on chemical and water usage and low waste generation. This makes it very environment-friendly. Furthermore, the combination of the Nanollose’s Tree-Free cellulose, along with Birla Cellulose’s closed-loop lyocell production process, could potentially make this Tree-Free lyocell one of the most eco-friendly and sustainable fibers available.
The joint patent application strengthens the intellectual property portfolio of both companies and provides protection for this innovative Tree-Free fiber technology. The nullarbor lyocell fibers are produced using feedstock from industrial and agricultural organic waste.

Toray: conjugate spinning technology for fabric like Japanese paper

A polyester filament fabric that combines the softness, smoothness, and comfort of synthetic fibers with the natural feel and random unevenness of traditional Japanese paper has been developed by the fiber and textile manufacturer Toray Industries Inc., Osaka/Japan.
Unlike conventional fabrics, Camifu can match the Japanese paper features. The conjugate spinning technology, Nanodesign was used to develop a flat C cross-sectional shape that delivers a precise arrangement of 3 different polymers. It has arranged polymers with different heat shrinkage properties in special shapes on the left and right of a flat cross-section, with a soluble polymer in the fiber center.
Toray heat treated polymers on the left and right side of the fiber to bend along the fiber length. This, coupled with a flat shape, creates a unique twist and stretch. Varying the arrangement and shape of the polymer with adjacent fibers generates different torsional structures for each yarn, resulting in a yarn bundle structure containing complex voids.
A yarn bundle structure produces a random unevenness in the fabric texture so it feels like hand-made Japanese paper. Single yarns comprising polymers with different colorations and dyeability cover the fabric without aligning. Camifu is eco-friendly, as one of its polymer is recycled from film scraps.
A hollow structure inside the fiber was created by placing a soluble polymer within, augmenting yarn bundle voids from filament twisting during relaxing and weight reduction process on textile. This hollow portion imparts a lightness and resilient feel to the fabric. A precisely designed slit keeps functional agents within the fiber, making it possible to incorporate a range of features in the fabric.

Gerber: digitalization to transform for the pandemic era

Rather than stopping garment production and furloughing employees when the Covid-19 pandemic reached their home country, knitwear clothing manufacturer, Bonneterie Chanteclair, Saint-Pouange/France, developed a high-quality mask with a HEPA filter.
As Chanteclair began to receive many orders from regional administrations, they developed an eCommerce website to sell B2B and B2C. To help keep up with demand, the company began working with the supplier of integrated software solutions Gerber Technology, Tolland, CT/USA, to help them pivot their supply chain and remain agile.
Gerber worked with Bonneterie Chanteclair to digitally transform their supply chain so they were able to keep up with the high demand for protective masks. Chanteclair acquired Gerber’s full end-to-end solution, which includes Gerber’s pattern making solution, AccuMark, their automated nesting and cut planning solutions, AccuNest and AccuPlan as well as the Gerber Paragon. With this end-to-end solution, Chanteclair was able to fulfill a high demand for masks in a short period of time.
Since March 2020, Gerber’s PPE Task Force has helped over 1,700 companies pivot to PPE production and helped them keep their doors open through the Covid-19 pandemic.
