Copper Ammonia Fabric: Why is it the new favorite of sustainable fashion?

As the global textile industry pays more and more attention to environmental protection and sustainable development, a new type of fabric known as "breathing silk" - Copper Ammonia Fabric, has gradually come into the public eye. It not only feels smooth and has excellent breathability, but also has extremely high degradability, becoming an important promoter of environmentally friendly fashion.

What is copper ammonia fiber fabric? How is it different from ordinary fabrics?
Cupro fiber, also known as "copper ammonia silk" or "copper ammonia rayon", is a regenerated cellulose fiber, which is mainly made of cellulose in cotton linters dissolved in copper ammonia solution and then spun. Although its chemical treatment is more complicated, in essence, it belongs to the regenerated cellulose family with viscose and rayon.

Compared with traditional synthetic fibers, cuprammonia fibers have the following unique advantages:

The surface luster is natural and soft, and the feel is close to silk

It has strong moisture absorption and breathability, making it more comfortable to wear

The fabric has excellent drape, suitable for high-end fashion design

Natural source, biodegradable, and meets sustainable standards

The production process of cuprammonia fibers: a combination of environmental protection and technology

The manufacturing process of cuprammonia fibers is relatively complex, and its key steps are as follows:

Raw material selection: Cotton linters, a by-product of cotton processing, are selected.

Dissolution treatment: A mixed solution of ammonia water and copper salts (such as copper hydroxide) is used to dissolve cellulose into a spinning solution.

Wet spinning: The dissolved solution is extruded through a spinneret to form continuous fibers in a coagulation bath.

Washing and drying: Remove residual copper salts and chemicals to make it safe to wear.

Although this process involves chemicals, most of the current mainstream processes are equipped with a closed-loop circulation system to effectively recycle copper salts and ammonia water, greatly reducing the risk of environmental pollution.

What are the core performance advantages of cuprammonia fabrics?

The fabric properties of cuprammonium fiber determine its wide application in the high-end market and functional clothing.

1. High skin affinity and comfort
The cuprammonium fiber has a round cross-section and fine fiber diameter. In addition to the natural cellulose properties, it feels smooth and gentle, does not irritate the skin, and is suitable for infants and sensitive skin.

2. Excellent moisture absorption and perspiration wicking ability
Its moisture absorption is much higher than synthetic fibers such as polyester, and it can quickly expel body sweat and keep dry. It is the preferred fabric for summer clothing and underwear.

3. Elegant drape and silk-like luster
The cuprammonium fabric has good drape, and the clothes naturally fit the body curve, showing a soft contour, while maintaining a silk-like luster, combining comfort and beauty.

4. Anti-static and anti-pilling
The fiber structure is stable, and the humidity regulation ability is strong, so there is almost no static electricity or pilling phenomenon, the maintenance cycle is long, and the texture is long-lasting.

In what fields are cuprammonium fiber fabrics mainly used?
With the growing demand for environmental protection and high-quality life, cupro-ammonia fiber has been rapidly expanded in the following fields:

● High-end women's clothing and men's shirts
Because of its softness and good drape, it is very popular with designers, especially suitable for making close-fitting dresses, long skirts, shirts, etc.

● Underwear and pajamas
It is highly breathable and comfortable to the skin, making it an ideal material for high-end underwear brands.

● Baby and children's clothing
It is skin-friendly, non-irritating, naturally derived, environmentally friendly and safe, and is an ideal fiber for baby clothes and swaddles.

● Sustainable fashion and environmentally friendly brands
Many international environmentally friendly clothing brands (such as Stella McCartney and COS) have included cupro-ammonia fabrics in their product series, highlighting the concept of green environmental protection.

What is the future development potential of cupro-ammonia fabrics?
As the textile industry enters the "green and intelligent" transformation stage, cupro-ammonia fiber is considered to be one of the important solutions in the field of sustainable fashion with its advantages of natural degradability, resource recycling, comfort and beauty.

Especially in markets such as China and Europe that advocate environmentally friendly fashion, the awareness and application depth of cupro-ammonia fiber are rapidly increasing. Coupled with the continuous optimization of manufacturing technology, the cost of cuprammonia fabrics is gradually decreasing, and it is expected to further replace some viscose and rayon products in the future.

Today, when green consumption is gradually becoming a mainstream trend, cuprammonia fabrics are undoubtedly an important part of promoting the textile industry to move towards low-carbon and environmental protection.
