Bamboo Warm Velvet

Keeping warm is an important indicator of the comfort of autumn and winter products. Traditional methods of keeping warm usually use thick fabrics, cotton wool or down interlayers, fleece fabrics, etc. to achieve the insulation effect. Some also use coatings or laminations to make the clothing have better warmth retention. However, modern people have higher and higher requirements for the comfort, functionality and aesthetics of clothing. Traditional warm clothing is fluffy and bloated, which is not convenient for movement and lacks aesthetics.

With the development of science and technology and the improvement of living standards, people's requirements for the practical functions of fabrics and clothing tend to be diversified, so the development of bamboo warm velvet fiber products is of great significance.

Bamboo Warm® Velvet Functional Principle

　Main performance indicators of Bamboo Warm® velvet fiber

The strength and length of bamboo warm velvet fiber are similar to those of long-staple cotton, the fineness is similar to that of fine-staple cotton, and the quality and electrical resistance are better than ordinary polyester staple fibers.

When observing the fiber cross-section under a microscope, the hollow tubes of the fibers can make the fibers more fluffy, and the cavity provides still air, thereby improving the warmth retention of the fibers. Many capillaries are formed between the fibers in the fabric, forming an excellent moisture conduction system with the hollow tubes of the fibers, which evaporate and dry in the atmospheric environment through the clothing system, thereby regulating the human body temperature and increasing the dryness and comfort of the human body.

When the bamboo warm fleece fiber absorbs water, the hydrophilic groups in the fiber molecules combine with the water molecules, the kinetic energy of the water molecules is reduced, and at the same time converted into heat energy and released, generating heat. When water vapor is absorbed, latent heat of condensation also occurs.

　　Heating principle of bamboo warm velvet

Human skin cells are breathing all the time, expelling sweat. Fibers absorb the gaseous sweat released by the human body, convert it into liquid water, and release heat. Liquid water is transferred to the outside of the clothing through the fiber, ensuring the comfort of the human microclimate while making the human body feel hot, warm and comfortable.
