Product Knowledge
Cotton bamboo fabric has excellent hypoallergenic and antibacterial properties due to the inherent characteristics of bamboo fibers. Here's why cotton bamboo fabric is considered hypoallergenic and antibacterial:
Hypoallergenic Properties: Bamboo fibers have a smooth and rounded surface compared to other fibers like cotton or wool, which can have microscopic sharp edges. This smooth surface reduces the potential for irritation and allergic reactions on sensitive skin. As a result, cotton bamboo fabric is less likely to cause skin irritations or allergies, making it hypoallergenic and suitable for individuals with sensitive skin.
Natural Antimicrobial Agents: Bamboo contains a natural antimicrobial agent called "bamboo kun." Bamboo kun is an antimicrobial bio-agent that is resistant to bacteria, fungus, and pests. When bamboo is processed into fibers and woven into fabric, these antimicrobial properties remain intact. As a result, cotton bamboo fabric naturally inhibits the growth of bacteria, making it less likely to develop unpleasant odors caused by bacterial activity. This makes the fabric suitable for items like activewear, socks, and undergarments.
Moisture-Wicking: Bamboo fibers have excellent moisture-wicking properties, allowing them to absorb and evaporate moisture quickly. Moisture-wicking fabrics keep the skin dry and prevent the development of a damp environment, which can be a breeding ground for bacteria and other microorganisms.
Breathability: Cotton bamboo fabric is highly breathable, allowing air to circulate freely through the fabric. Proper ventilation helps in reducing the likelihood of skin irritations or rashes caused by trapped heat and sweat.
Micro-gaps: Bamboo fibers have micro-gaps and micro-holes in their structure. These gaps create a highly porous surface that can absorb and hold a significant amount of moisture.
Capillary Action: The micro-gaps in bamboo fibers act like capillaries, drawing moisture (such as sweat) away from the body. This capillary action helps distribute the moisture throughout the fabric, allowing it to evaporate more quickly.
What printing inks are specially used for cotton and bamboo fabrics?
For cotton and bamboo fabrics, different types of printing inks are used, considering the fabric's composition and desired printing method. Some commonly used printing inks for cotton and bamboo fabrics include:
Reactive Dyes: Reactive dyes are specifically used for printing on cellulosic fibers like cotton, bamboo, and viscose. They chemically react with the fiber molecules to form a strong and permanent bond. Reactive dyes are known for their excellent color vibrancy, colorfastness, and wash resistance on cotton and bamboo fabrics.
Pigment Inks: Pigment inks are water-based inks that sit on the surface of the fabric rather than chemically bonding with the fibers. They are commonly used for digital printing on cotton and bamboo fabrics. Pigment inks provide vibrant colors, especially on light-colored fabrics, but may require additional post-treatments like heat setting or fixatives to enhance durability.
Water-Based Inks: Water-based inks are eco-friendly and suitable for screen printing on cotton and bamboo fabrics. They are water-soluble and non-toxic, making them a popular choice for printing on natural fibers.
Discharge Printing Inks: Discharge printing inks are used to create designs on dark-colored cotton and bamboo fabrics. They work by removing or bleaching the color of the fabric where the ink is applied, creating a lighter colored design.
Reactive Digital Inks: For digital printing on cotton and bamboo fabrics, reactive digital inks are used. These inks are specially designed for inkjet printers and have similar properties to traditional reactive dyes, offering vibrant colors and excellent washfastness.
