Context

  • The North Eastern Handicrafts and Handlooms Development Corporation (NEHHDC) under the Ministry of Development of North Eastern Region (DoNER), Govt. of India, has successfully obtained the prestigious Oeko-Tex certification for its Eri Silk, directly from Germany.

Details

Eri Silk

  • Origin: Eri silk is native to the northeastern states of India, particularly Assam and Meghalaya.
  • Etymology: The name "Eri" comes from the Assamese word "era," meaning "castor," as the silkworms feed on the castor plant.
  • Sustainability: Known as "Ahimsa" or "peace" silk, Eri silk is cruelty-free, harvested after the silkworms naturally exit their cocoons.

Production Process

  • Silkworm Species: Eri silk is produced from the Samia ricini
  • Diet: The silkworms primarily feed on the leaves of the castor plant (Ricinus communis).
  • Lifecycle: The production cycle from egg to cocoon takes approximately 45-50 days.
  • Harvesting Method: After the moths leave the cocoons, the cocoons are boiled to remove sericin, and the fiber is spun into yarn.
  • Spinning: The yarn is spun using handlooms, floor looms, or power looms. The process is labor-intensive due to the short filaments of the silk.

Unique Characteristics

  • Texture: Eri silk is soft, warm, and has a woolly texture, making it comfortable for all-season wear.
  • Durability: It is durable with good tensile strength and elasticity.
  • Color: Naturally off-white, Eri silk can be dyed using natural or chemical dyes, although plant-based dyes are commonly used in traditional practices.

Environmental and Ethical Aspects

  • Cruelty-Free: Eri silk is known as Ahimsa silk because the moths are not killed during the process.
  • Eco-Friendly Production: The production process is environmentally friendly with minimal waste, aligning with the principles of a circular economy.
  • Local Economy: Eri silk production supports rural livelihoods, particularly empowering women through cottage industries.

Geographical Significance

  • Major Producing Regions: Assam and Meghalaya are the primary producers, with Meghalaya being renowned for its high-quality Eri silk.
  • Climate: The warm and humid climate of Northeast India is ideal for Eri silk cultivation.

Applications and Uses

  • Apparel: Eri silk is used to make a variety of garments, from shawls to sarees.
  • Furnishings: It is also used in home furnishings due to its soft texture and durability.
  • Artisanal Products: Increasingly popular in sustainable fashion and artisanal markets.

Oeko-Tex Certification

  • Oeko-Tex is an international certification system designed to ensure that textiles and leather products are tested for harmful substances and produced in environmentally and socially responsible ways.
  • The certification is highly respected in the textile industry, providing a reliable and standardized method for assessing product safety.

Types of Oeko-Tex Certifications

Oeko-Tex offers several types of certifications, each focusing on different aspects of textile and leather product safety and sustainability:

  • Standard 100 by Oeko-Tex:Focuses on testing textiles at all stages of production for harmful substances. It is one of the most widely recognized certifications.

Global Reach

  • Oeko-Tex certifications are recognized globally, with partner institutes in over 60 countries.
  • This wide recognition offers a competitive advantage to manufacturers by allowing them to certify products once and have that certification accepted across multiple markets.
  • The certification also reassures consumers about the safety and environmental responsibility of the products they purchase.

Criteria and Testing

The Oeko-Tex certification system tests for a wide range of harmful substances, including:

  • Regulated substances:Such as azo dyes, formaldehyde, and nickel.
  • Non-regulated substances:That are harmful to health but not yet legally controlled.
  • REACH Regulation Compliance:Ensures adherence to European chemical safety regulations.
  • Product Classification:Based on the degree of skin contact, ranging from products for babies (Class I) to products with no direct skin contact (Class IV).

Silk

  • Silk is a natural protein fiber produced by certain insect larvae, notably the mulberry silkworm (Bombyx mori), during the formation of cocoons.
  • The shimmering appearance of silk fabric is due to its triangular prism-like structure, which refracts light at different angles, creating a lustrous and luxurious look.

Historical Background

  • Silk production, known as sericulture, has its origins in China, dating back to around 2696 BC.
  • For centuries, China held a monopoly on silk production, keeping the process a closely guarded secret.
  • The Byzantine Empire eventually acquired the knowledge in the 6th century AD, and silk production spread across Europe and Asia.
  • Today, more than 60 countries produce silk, with China, India, and Brazil being the largest producers.

Types of Silk

Silk comes in various types, each with unique characteristics:

  • Mulberry Silk: The most common type, known for its strength, softness, and smooth texture.
  • Eri Silk: Also known as 'peace silk' because it does not require killing the silkworms. It is heavier and more durable than mulberry silk.
  • Tussar Silk: Produced from wild silkworms, mostly found in India. It has a natural golden color.
  • Muga Silk: Exclusive to Assam in India, this silk is known for its natural golden hue and durability.
  • Spider Silk: Extremely rare and expensive, spider silk is known for its remarkable strength, but it's not widely used due to the challenges of production.

Silk Production Process

The production of silk involves several steps:

  • Cultivation of Silkworms: Silkworms are cultivated and fed on specific leaves (e.g., mulberry leaves for Bombyx mori).
  • Spinning of Cocoons: The silkworms spin cocoons made of raw silk filaments.
  • Extraction: The cocoons are soaked in hot water to soften the sericin (gum) that holds the cocoon together, allowing the silk filaments to be unwound.
  • Weaving: The silk threads are spun and woven into fabric.

Global and Indian Silk Industry

  • Global Production: China is the largest producer and exporter of silk, followed by India, Brazil, Uzbekistan, and Thailand. Silk is used globally in fashion, home décor, and industrial applications.
