Its long, pure white silk filaments are carefully woven into a fine silk fabric. This material is not only incredibly soft and luxurious but also gentle on the skin.

The Uniqueness of Mulberry Silk Fabric

What is Mulberry Silk?

Real silk is an incredibly unique and luxurious fabric, with numerous health benefits that set it apart from other materials. Among the various types of silk, mulberry silk stands out as the highest quality silk fibre available. But what is mulberry silk, and what makes it so special?

Mulberry silk thread is produced from the Bombyx mori moth, whose silkworms feed exclusively on white mulberry leaves from mulberry trees native to India and central China. This results in pure mulberry silk threads, which have a soft feel and a uniformly colored, lustrous appearance.

The finest 100% mulberry silk fabric is used to create high-quality silk bedding, such as mulberry silk pillowcases, duvet covers, and silk comforters.

One of the many benefits of mulberry silk is that it is a natural and hypoallergenic material. The long-fiber silk, derived from the silk cocoons of domesticated silkworms, has natural properties that resist dust mites and prevent allergic reactions for those with sensitive skin.

Additionally, mulberry silk bedding, like silk pillowcases and silk comforters, can enhance your beauty sleep experience by promoting a soft and gentle touch on your skin and hair.

OEKO-TEX certified mulberry silk goes through a rigorous production process that ensures no harmful chemicals or toxic substances are present in the silk production. 

This certification guarantees that the type of silk product you are using, such as a mulberry silk pillowcase or silk bedding, is safe and environmentally friendly.

Beauty Benefits of Silk

Cotton tends to dry out your skin and hair while silk does not. This is because silk's tight weave of long-fiber strands makes the fabric moisture-retaining. Silk is not moisture-absorbent like cotton. It leaves your skin feeling fresh and vibrant instead of dull and flaky.

Silk is also hypoallergenic and can prevent allergic reactions and ease skin conditions. Silk also contains albumen at the cellular level. This reduces the appearance of fine lines and wrinkles. Long-term use results in skin that looks and feels much younger.

Your hair also benefits from the use of silk pillowcases and hair accessories. Unlike other fabrics that cause hair to become tangled and frizzy, silk's smooth surface allows hair to gently glide across it.

The Cooling Effect of Silk

The finest mulberry silk is also known for regulating your body temperature. This allows you to be more comfortable while you are sleeping. While everyone can benefit from this, it is especially beneficial for those suffering from hot flashes.

What Exactly is OEKO-TEX Standard 100?

Origins of the Certification Process

Every fabric label carries vital information about the material. The Standard 100 certification by OEKO-TEX is a method of testing that can identify many chemicals and irritants that are commonly found in the textile supply chain. Developed in Europe by a textile institute, it has become the global standard for certifying fabrics.

Once the raw material has gone through a rigorous testing process and is determined to be free of all hazardous substances, it can carry the Standard 100 Certification label by OEKO TEX.

Consumers Demand More

This label works to create trust with consumers around the world who are more and more demanding products of a different product class. Consumers who care about climate change want to know that manufacturers are following sustainability standards and prohibiting harmful levels of toxic substances. Especially for products that are going to have skin contact.

Standard 100 OEKO-TEX Certification

To receive the Standard 100 certification, an independent lab must test the raw material used in the fabric. Many chemicals and substances are on the screening list. They include:

      • Heavy metals
      • Phthalates
      • Colorants
      • Pesticides
      • Formaldehyde
      • Chlorinated phenols

Many types of fabric can contain these harmful substances. Even organic cotton bedding and other types of silk bedding have tested positive.

Products fall into different categories depending on how they are used. Our products fall under the category of baby items and products that come in contact with the skin.

What Sets the Standard 100 OEKO-TEX Certification Apart?

GOTS Certifications

Across the globe, there are various certifications that textile companies can choose from. One is the Global Organic Textile Standard or GOTS. The GOTS standard means that the textile products are made from at least 70% natural organic fibers and have not been treated with any type of hazardous or toxic chemical or substance. It must be colored with non-toxic colorants or dyes and meet strict environmental standards.

OEKO-TEX Certifications

OEKO-TEX is a strict testing method that must be renewed each year. A substantial amount of the fabric must be submitted during the certification process so that many different tests can be performed.

This includes the raw silk used to produce mulberry silk products. Every test performed is accurately documented in great detail and will be recorded and filed with the sample. Once the sample has been tested and has passed, it can carry the OEKO-TEX Standard 100 label.
