The Synthetic Silk Revolution: Between Innovation and Sustainability

Understanding artificial material: rayon

Synthetic silk is actually a regenerated cellulose-based fiber, usually made from wood pulp. It is more precisely called rayon or viscose.

The process for obtaining this material resembles that of making paper. Paper pulp is extruded through fine needles directly into a chemical bath to form long, continuous filaments. These threads are then chemically treated to become shiny and soft to the touch.

Thanks to this innovative process, rayon takes on an appearance very similar to silk with shimmering reflections. It also has a soft texture and good absorption of the dye.

Manufacture and characteristics of synthetic silk

The manufacture of synthetic silk is based on the regeneration of cellulose generally coming from softwoods such as pine or fir.

After a chemical treatment with caustic soda, the cellulose fibers are dissolved then extruded through a die to form continuous filaments of rayon. These are then stretched, washed and dried.

The main characteristics of synthetic silk are:

• Shiny appearance and soft to the touch very similar to silk
• Good absorption of dyes for a wide variety of colors
• Easy weaving to make all kinds of clothes and fashion accessories
• Affordable price compared to natural silk
• Good resistance to light (no discoloration)
• Low elasticity and abrasion resistance

In summary, it is an excellent imitation of silk at low cost for certain specific uses.

Main types of synthetic silk

There are three main types of synthetic silk:

• The standard viscose: the most widespread, made from wood pulp.
• The high tenacity viscose: more resistant thanks to the alignment of the fibers.
• The modal: very soft variety, made from beech and oak.

Modal is the most luxurious and comfortable variety, while high tenacity viscose offers better resistance over time.

Standard viscose nevertheless remains the type most used in the manufacture of clothing and household linens due to its reduced cost and its satisfactory properties for these uses.

Advantages and disadvantages of this synthetic textile fiber

Synthetic silk has certain advantages over natural silk:

• Much more affordable price
• Easy dyeing in a wide variety of vibrant colors
• Soft, shiny and luxurious touch
• Easy maintenance, supports frequent washing
• Good resistance to mold and insects
• Low shrinkage in washing
• Hypoallergenic, suitable for sensitive skin

Its disadvantages are:

• Less resistant and elastic than real silk
• Wrinkles easily
• May shrink or stretch with wearing and washing
• Less durable over time
• Less ecological production (chemical solvents)

At The Oversized Hoodie®, we are always looking for the most comfortable and durable textiles for our collections. Although synthetic silk is not perfect, it is excellent value for money for some of our fashion accessories and detachables.

Dyeing and color of synthetic silk

Synthetic silk has excellent dye affinity, meaning it absorbs dyes and pigments very well.

We can therefore obtain a wide range of bright and deep shades which give a rich and shimmering appearance to the fabric.

Unlike certain synthetic fibers such as polyester, the colors do not fade over time and retain their original shade well.

This property allows synthetic silk to be dyed in all colors, from the lightest to the darkest, to satisfy the most varied desires.

Applications in Fashion

Thanks to its aesthetic qualities and pleasant feel, synthetic silk is widely used in the fashion industry, particularly for:

Pillowcase and accessories

Synthetic silk is ideal for bedding such as pillowcases or duvet covers. Its soft touch and easy maintenance make it an optimal choice for a luxurious feeling every day.

It is also found in scarves, scarves and squares in silk where it offers fluidity and lightness at a lower cost.

Bed linen

The sheets and duvet covers in synthetic silk provide a very pleasant feeling for the skin as well as a beautiful, shiny appearance for the bedroom.

It is an affordable alternative to natural silk bedding sets while still maintaining the luxurious look. Machine maintenance also avoids ironing chores!

Synthetic silk for eyelash extensions

Due to its lightness and softness, synthetic silk is widely used for eyelash extensions. The tufts of artificial eyelashes are fixed with glue to a silk filament in order to achieve a comfortable and natural pose.

Rayon in the making of curtains and sheets

Rayon is very present in furnishing fabrics such as curtains, wall hangings, tablecloths or bed sheets. It provides fluidity and softness to these textile items while remaining economical.

Synthetic silk or natural silk

Although similar in appearance, synthetic silk and natural silk have different characteristics and uses.

Is synthetic silk a good alternative to natural silk?

For certain specific uses requiring softness and fluidity at a low price, synthetic silk is a very good option. This is particularly the case for lingerie, fashion accessories or bedding.

It may be suitable occasionally for clothing but its low resistance to abrasion makes it less suitable for regular use.

For pieces intended to last or intensive use, it is better to favor real silk.

What are the types of natural silk?

The natural silk comes exclusively from the spinning of the cocoons of the silkworm (bombyx). We distinguish:

• The wild silk (tussah)
• mulberry silk
• The spider silk
• The lotus silk

These different types of natural silk are characterized by their great robustness, their subtle touch as well as their shimmering beauty.

Choosing Synthetic Silk: How to Recognize Quality?

To ensure the quality of a synthetic silk fabric, a few key points:

• Examine the fineness and regularity of the weaving
• Check the shininess and the hang of the fabric
• Test the softness to the touch by rubbing gently
• Check the fastness of the dye and the uniformity of the color
• Gently stretch a wire to check its resistance

Quality synthetic silk should not have any irregularities, faded dye, or threads that break easily when stretched. Favor Oeko-Tex certifications for greater safety.

How to properly maintain synthetic silk?

Some tips for preserving your synthetic silk items:

• Hand wash in cold water, with mild soap
• Rinse thoroughly to remove any soap residue
• Dry flat, in the open air, away from sun
• Iron if necessary at low temperature, with a cloth
• Never put in tumble dryer
• Store folded in a cotton cover away from light

By following these recommendations, your synthetic silk accessories and clothing will maintain their beautiful appearance for a long time.

We recommend washing your clothes containing synthetic silk by hand and ironing them at low temperature to preserve their beautiful appearance over time. Proper maintenance will allow you to enjoy their pleasant touch for a long time!

Conclusion

Ultimately, synthetic silk is an interesting economical alternative to natural silk for certain uses, even if it remains less resistant.

With its soft touch, its beautiful drape and its aesthetic qualities, it is perfect for bedding, household linens, fashion accessories and the lingerie.

For more robust clothing or intensive use, it is nevertheless better to opt for real silk, which remains the must in terms of luxury and durability.
