DuPont and NIPI™, makers of Thindown®, Partner to Create a Revolutionary Next Generation of Down Fabric (2/1/19)
DuPont Industrial Biosciences (DuPont) and Natural Insulation Products Inc. (NIPI™) today announced
a collaboration to create a new category of insulation. This partnership brings together two forward-
thinking leaders in the materials space to explore new, innovative materials that will combine DuPont™
Sorona® fibers and Thindown® to enhance the warmth, comfort and design flexibility of insulation.
Thindown® is the world’s first and only 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® fiber – a high-performance fiber made
from renewable plant-based ingredients. The two brands are exploring new developments to
seamlessly combine the softness, drape and stretch recovery of Sorona® fibers 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® fibers – can further revolutionize down applications and create a new category
The blend of Sorona® fibers and Thindown® can 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. Additionally, with the use of bio-based Sorona® fibers, the collaboration
yields a more sustainable insulated material option versus traditional down, which comes from animal
plumage, or nylon, which requires 40 percent more energy to produce.
“We are pleased to partner with DuPont, the creator of some of the world’s most outstanding fibers to
bring together ‘the best of Science and the best of Nature’ to create the next evolution of down
fabrics,” said Ronie Reuben, the inventor of Thindown®.
