Cupro & Cupro Bemberg™ - All you need to know

We're passionate about fabric at Sew Me Sunshine. Here's our guide to everything cupro, and tips on how to sew with this type of dressmaking fabric.

WHAT IS CUPRO & BEMBERG™ CUPRO?

  • Cupro is short for cuprammonium rayon, it is made from cotton production waste (cotton linter). It is often referenced as a sustainable fibre because it is a byproduct of the cotton industry, however, hazardous chemicals are required to manufacture cupro (solution of copper and ammonia) that can be toxic to both people and the environment when they are not disposed of correctly
  • Production of cupro in the USA has been banned due manufacturers failing to comply with basic air and water regulations
  • It is lightweight, drapes beautifully and has a similar feel to silk, unlike silk it is a vegan product 
  • Bemberg™ Cupro is a brand of cupro produced by Asahi Kasei. These fibres are manufactured using innovative technology and techniques that reduces the environmental impact. They strictly control the chemical substances used in the manufacturing process and have introduced a closed-loop production system that recovers and reuses copper and ammonia. They also take into account social elements by collaborating with various stakeholders to achieve a sustainable society, for example, working towards goals to increase the income of workers and helping women have greater opportunities

TIPS ON HOW TO SEW WITH CUPRO:

  • Pre-wash your fabric as they are prone to shrinking (30 degrees, air dry)
  • Use a new sharp needle. When sewing with cupro it is advisable to use a microtex needle
  • Use fine sharp pins
  • Take your time when cutting out your fabric and make sure your grainlines are lined up
  • Use a rotary cutter and cut on the flat when cutting out 
  • Use woven interfacing when sewing with woven fabric
  • Press seams before stitching with a medium hot iron with lots of steam
  • Stay stitch (a line of stitching sewn around an edge within the seam allowance to prevent the fabric from stretching out)
  • Make sure you let your garment hang for a day or more before finishing any hems 
  • Sew a line of stitching before pressing the hem as this will help you to achieve a straight hem
  • Hand baste tricky areas such as zips, cuffs, collars pockets etc 
  • You can use spray starch when cutting out your fabric as this will make the fabric more sturdy and help with accuracy
