Joslin sources textiles and yarns that are high in quality, planet-friendly, and traceable to the source. Joslin uses fabrications derived from natural compositions in each design.
Joslin's linen is certified with European Flax®. It is of traceability to the Normandy region of France (Terre De Lin), a terroir of excellence for the flax culture and traditional agriculture that positively affects the ecosystem diversity and offers an environmental pause for soil quality and biodiversity.
From the field to the scutched fibre, the production of Joslin's linen is fully traced, which allows a better follow-up of the fibre lots quality. The combed flax is imported into a mill in Jiangsu, China, in bales where it is spun and then woven into batiste cloth. Linen uses approximately 90% less embodied energy in its manufacture than polyester, fast fashion's most common fabric, and is long-lasting and durable in the wardrobe.
Linen is made from the flax plant and is one of the most naturally occurring sustainable fibres.
Flax linen has the following benefits:
- Traditional flax cultivation has positive effects on ecosystem diversity and offers an environmental pause for soil quality and biodiversity
- The flax plant and crop respects the environment and preserves the land, as well as the surrounding plants and wildlife
- Flax protects the soil and water resources; it requires zero irrigation as rainwater is enough for the crop to grow naturally
- No pesticides are used or required to protect the crop while growing. Thus there are no greenhouse gas emissions
- No genetically modified organisms
- The entire plant is used, and no part of the plant is wasted
- Carbon sink, the crop absorbs more carbon than it puts out
- Field retting
- Mechanical scutching to yarn
- Low carbon emissions
- Biodegradable properties
Approximately 70% or more of Joslin's garments are made from linen.
Ramie has many similar characteristics to linen, but ramie fibers are sourced from Chinese Nettle, native to East Asia. The ramie plant grows quickly and can be harvested three to six times a year. Ramie is also grown without pesticides and is watered from rainfall alone. It is naturally growing and biodegradable.
Joslin's ramie is grown in China and is woven into ramie organdy and batiste cloth.
Joslin uses ramie organdy throughout the sleeves of many dresses and tops as a contrast fabric that molds nicely with linen.
Organic cotton is certified to organic agricultural standards.
Organic cotton farming does not allow the use of toxic chemicals or GMOs (genetically modified organisms). Instead, it combines tradition, innovation, and science to benefit the shared environment and promote a good quality of life for all involved.
Organic cotton farming sustains the soil and ecosystems by using natural processes rather than artificial inputs.
Growing organic cotton keeps farmers and their families safe. They are not exposed to toxic chemicals in the field or through their food and water supply. It also means farmers grow more than one crop, which supplements their food and income.
To the best of our knowledge, Joslin strives to ensure non-GMO cotton is used throughout all manufacturing.
Joslin uses GOTS certified organic cotton across wovens and fully fashioned knitwear.
GOTS is the worldwide leading textile processing standard for organic fibres, including ecological and social criteria, backed by independent certification of the entire textile supply chain. All chemical additives, such as dyes, adjuvants, must meet specific environmental standards and toxicology standards. An effective sewage treatment plant must accompany all water treatment-related production, and all treatment equipment must meet minimum social standards.
100% of Joslin's woven garments use GOTS Certified Organic Cotton, including Joslin's denim.
Approximately 90% of Joslin's fully fashioned knitwear garments are made from 95% GOTS Certified Organic Cotton / 5% GCS Cashmere Yarn.
Joslin's cashmere is sourced from ethical farms in Inner Mongolia, which are regularly monitored to ensure the best living standards of the animals. Because of unique inventory control software, all of Joslin's cashmere fibers are traceable to a specific region, down to each cone.
Joslin's cashmere is certified with GCS (Good Cashmere Standard), SFA (Sustainable Fibre Alliance), and ICCAW (International Cooperation Committee of Animal Welfare).
Joslin blends cashmere fibre (5%) with GOTS certified organic cotton to soften the hand-feel of our cotton knitwear. Approximately 90% of Joslin's fully fashioned knitwear garments are made from 95% GOTS Certified Organic Cotton / 5% GCS Cashmere Yarn.
Joslin's merino wool is certified by the Responsible Wool Standard (RWS).
The RWS is an independent, voluntary standard. On farms, the certification ensures that sheep are treated with respect to their Five Freedoms and provides best practices in the management and protection of the land. Through the processing stages, certification ensures that wool from certified farms is correctly identified and tracked.
Approximately 10% of Joslin's fully fashioned knitwear garments are made from RWS Certified Merino Wool. Joslin uses Merino Wool sparingly as it is hot to wear for the Australian climate.
Joslin's silk garments are all produced through the one manufacturer, Wujiang Silk Garment Co Ltd in Suzhou, Jiangsu, China. Suzhou has been at the centre of China's illustrious silk trade for centuries, and still uses ancient techniques and fine craftsmanship. Silk is a natural protein fibre, composed mainly of fibroin and is produced by insect larvae to form cocoons.
Synthetics and plastics are generally not used at Joslin, although they are not 100% avoidable in garment production. Synthetic textiles are non-compostable, non-biodegradable, and have 'micro-plastic properties that profoundly affect the planet's land-fill levels and oceans. They have a negative environmental impact and carbon emissions of producing polyesters and acrylics through petroleum.
In Joslin garments, synthetics and plastics are only used when there is no natural alternative, or it benefits that natural composition. It is not always possible to avoid synthetics and plastics in garment production - buttons, zips, and fusings are the benchmark of standard manufacturing and garment construction. There is currently no natural alternative that is commercially viable for fusing.
Minimal animal products are used in the production of Joslin garments. Currently the only animal products used are GCS Cashmere, RWS Merino Wool and Silk. Joslin stands for the prevention, reduction and eradication of animal suffering in the production supply chain and works in line with the five freedoms of animal welfare.
Joslin strictly prohibits the below animal products in their apparel and accessories:
- Exotic animal skin
Dyes & Chemicals.
All of Joslin's manufacturers and dye-houses ensure yearly certification of OEKO-TEX® 100 STANDARD, meaning no harmful chemicals are used during the dying process, ensuring customer confidence, high product safety, and healthier waterways.
OEKO-TEX® undertakes extensive product checks and regular company on-site visits with factories worldwide to ensure that the industry has a globally sustainable awareness of the responsible use of chemicals.
