Copper Ammonia Fabric: A fiber art that combines luxury and environmental protection

In the textile world, Copper Ammonia Fabric has gradually come to the fore with its unique charm and performance, becoming the new favorite of the fashion industry. This regenerated cellulose fiber not only has a silky texture, but also integrates the environmental protection concept of modern technology, allowing people to feel the harmonious coexistence of nature and technology while pursuing fashion.

Cuprammonium fiber, scientifically known as Cuprammonium Fibre, was born from the re-creation of natural cellulose. By dissolving cotton linters or other natural cellulose raw materials in a concentrated ammonia solution of copper hydroxide or alkaline copper salt to form a spinning solution, and then through a wet spinning process, a hydrated cellulose fiber with a soft luster and soft feel is finally generated. This process not only reflects the full utilization of natural resources, but also demonstrates the wisdom and innovation of mankind in the field of fiber manufacturing.

In the production process of cuprammonium fiber, the spinning solution has extremely high plasticity and can withstand high stretching, so it can be made into extremely fine fibers, and the linear density of a single fiber is usually between 0.44 and 1.44dtex. This fineness makes the fabric made of cuprammonia fiber feel more delicate, the luster is softer, and it has an elegant style like silk.

The performance of cuprammonia fiber is not only reflected in its appearance and feel, but also in its intrinsic quality. Cuprammonia fiber has hygroscopicity, and the moisture regain can reach 12% to 13.5%, which is better than cotton fiber and similar to viscose fiber, but the water absorption is about 20% higher than viscose fiber. This feature allows cuprammonia fiber to keep the skin dry and comfortable during wearing, and is particularly suitable for wearing in humid or sweaty environments.

The dyeing performance of cuprammonia fiber is also very outstanding. Due to its non-cortical structure, it has a greater affinity for dyes, fast coloring speed, and high dyeing rate. This allows cuprammonia fiber to present brighter and fuller colors during the dyeing process, satisfying people's pursuit of fashion and personality.

Cuprammonia fiber also has good mechanical properties and heat resistance. Its breaking strength is slightly higher than that of viscose fiber, and its dry breaking strength can reach 2.6 to 3.0 cN/dtex, and its wet-dry strength ratio is 65% to 70%. At the same time, the strength of cuprammonia fiber is stable below 150 degrees, but it will burn if it exceeds 180 degrees. These characteristics enable cuprammonia fiber to withstand certain stretching and deformation in clothing production, and maintain the shape and beauty of clothing.

The performance of cuprammonia fiber has made it widely used in many fields. In the field of clothing, cuprammonia fiber is often used to make high-end suit linings, women's suits and various blended high-end coats. Its delicate feel, elegant luster, good moisture absorption and dyeing properties make cuprammonia fiber products popular in the fashion industry.

Cuprammonia fiber is also highly praised for its environmental protection characteristics. As a regenerated cellulose fiber, the raw material of cuprammonia fiber comes from natural cellulose, and the impact on the environment during the production process is relatively small. Cuprammonia fiber can also be biodegraded, which is in line with the trend of environmentally friendly clothing. This characteristic makes cuprammonia fiber have a broader application prospect in today's pursuit of sustainable development.
