DuPont Industrial Biosciences (DuPont) and Thindown by NIPI have announced a collaboration to create a new category of insulation at Outdoor Retailer in the US last week. This partnership brings together two forward-thinking leaders in the materials space to explore new, innovative materials that will combine DuPont Sorona fibres and Thindown to enhance the warmth, comfort and design flexibility of insulation.

Thindown is a down fabric, which offers the coveted benefits of a versatile material. As the company looks to elevate its performance attributes and sustainable ingredients, it has partnered with DuPont Industrial Biosciences’ using its Sorona fibre – a high-performance fibre made from renewable plant-based ingredients. The two brands are exploring new developments to seamlessly combine the softness, drape and stretch recovery of Sorona fibres and down, utilizing the proprietary process from Thindown to create a new category of a blended down insulated fabric.

“We are constantly exploring new opportunities to develop and market innovative solutions across industries, and this unique collaboration underscores that commitment to delivering on both high performance and sustainability in apparel,” said Renee Henze, Global Marketing Director, DuPont Industrial Biosciences. “The breakthrough technology of Thindown – coupled with the textile innovation of Sorona fibres – can further revolutionize down applications and create a new category of insulation.”

The blend of Sorona fibres and Thindown is designed to eliminate several drawbacks associated with the use of traditional down filling. The combination can reduce cold spots with a single sheet of fabric versus quilted sections, delivering greater warmth and breathability, while simultaneously adding drape and stretch for greater movement, according to DuPont. Additionally, with the use of bio-based Sorona fibres, the collaboration yields a more sustainable insulated material option versus traditional down, which comes from animal plumage, or nylon, which requires 40% more energy to produce.

“We are pleased to partner with DuPont, the creator of some of the world’s most outstanding fibres to bring together ‘the best of Science and the best of Nature’ to create the next evolution of down fabrics,” commented Ronie Reuben, the inventor of Thindown.
