TEXTILES & TRACEABILITY.
Joslin's linen is certified with European Flax®. The European Flax® Charter, signed by all the Flax producers, guarantees local farming that respects the environment and commits to zero irrigation, zero GMO, and zero waste.
All work is done in compliance with the International Labour Organisation (ILO). The ILO is devoted to promoting social justice and internationally recognised human and labor rights, pursuing its founding mission that social justice is essential to universal and lasting peace.
Joslin's European Flax® is of traceability to the Normandy region of France and Belgium, 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.
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.
Joslin's Organic Cotton is verified from farm to textile/yarn stage with GOTS (Global Organic Textile Standard). Joslin is aiming to obtain brand certifications for the Global Organic Textile Standard (GOTS) to be able to make strong environmental claims on our Organic Cotton products and showcase our third-party certifications via logos on our products to our community.
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.
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).
To become certified with GCS, cashmere farmers completed a comprehensive series of questions on their livestock-keeping practices. Based on these results, independent third parties visit the farms to verify the proper implementation of the standard.
Joslin's merino wool is certified by the Responsible Wool Standard (RWS).
The Responsible Wool Standard (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.
All of Joslin's textile and trim 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.
Joslin’s fabric covered button moulds are made from Post-Consumer Recycled Polyester.
Joslin's Post-Consumer Recycled Polyester Button Moulds are verified from raw processing stage to trading stage with GRS (Global Recycle Standard). Joslin is aiming to obtain brand certification for the GRS (Global Recycle Standard) to be able to make strong environmental claims on our post consumer recycled polyester buttons and showcase our third-party certifications via logos on our products to our community.
The Recycled Claim Standard (RCS) and Global Recycled Standard (GRS) are international, voluntary standards that set requirements for third-party certification of recycled input and chain of custody. The shared goal of the standards is to increase the use of recycled materials. The GRS includes additional criteria for social and environmental processing requirements and chemical restrictions.
Joslin’s viscose voile lining is certified with FSC® (Forest Stewardship Council®). The Forest Stewardship Council promotes environmentally appropriate, socially beneficial, and economically viable management of the world’s forests.
Silk is a natural protein fibre, composed mainly of fibroin and is produced by insect larvae to form cocoons.
Joslin's silk and silk garments are all produced through the one manufacturer, with a vertical operation, Wujiang Silk Garment Co Ltd in Suzhou, Jiangsu, China.
This means Joslin's entire manufacturing process of silk is traceable, from farming and harvesting, spinning and final production.
Suzhou has been at the centre of China's illustrious silk trade for centuries, and still uses ancient techniques and fine craftsmanship.
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 southern China and is woven into ramie organdy and batiste cloth.
Minimal animal products are used in the production of Joslin garments. Currently the only animal products used are Cashmere, 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 Leather, Exotic Animal Skin, Fur, Angora, Feathers and Down products in their apparel.
Joslin uses the same textiles, materials, trims, and raw materials in each collection to eliminate dead stock waste. This is why, while shopping for our products, you will see a minimal variety of fabrications used by Joslin. If one of Joslin's suppliers overbuys or overproduces a textile, the overs will be cut into the following purchase order of apparel instead of going to dead stock.
Synthetics and plastics (Polyester, Acrylic, Nylon) are 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.
