The fibers do not retain water, yet the fabric remains dry: The Boulder Industrial Soft Hygroscopic Nonwoven Fabric with Conductive Properties is dry wicking.
Unlike traditional textile fabrics, the soft and water repellent nonwoven fabric has no interwoven warp and weft structure. Instead, it relies on the network formation of fibers and functional modification techniques to allow the fibers to interlock and form a structure. Fine diameter fibers combined with the softening forming process result in a uniform and fluffy fabric surface that remains soft and moist in both dry and wet conditions, and is not prone to hardening or becoming rough. The loose arrangement of fibers creates a large number of tiny pores, allowing air to flow freely, and when in contact with the skin, the friction sensation is relatively weak, reducing the discomfort of dampness and heat. The delicate touch and controllable moisture wicking ability are integrated into this network structure, making it a commonly used base material in fields such as hygiene care, skincare, and medical dressings.Softness is its obvious characteristic, while dryness comes from a carefully designed "failure" it must allow water to pass through but not leave any water behind. Polypropylene fibers themselves repel water molecules, with a contact angle far above 90 degrees. Liquid droplets falling on them will roll into beads and roll off. To allow urine or sweat to flow downward smoothly, the fiber surface needs to be "persuaded" to accept water: during spinning or network formation, introduce hydrophilic modification to make the fiber surface attach polar groups, and the contact angle subsequently drops to a level sufficient for liquids to spread out. Here lies a paradox that is easily overlooked the rewetting rate of the hydrophilic nonwoven fabric is only around 0.4%, and it hardly retains water. Its task is not to absorb but to conduct: liquid droplets penetrate the fiber network gaps, pass through the interlaced channels of the fibers to reach the absorption core below, and the surface then recovers dryness. With a properly adjusted hydrophilic formula, the moisture wicking effect can still remain stable after multiple contacts with liquids, meeting the requirements for repeated liquid absorption.The material itself also has the advantages of cleanliness and stability. The production process has good control over fiber shedding, with less debris and less residue of fine fibers. The fabric surface tension is uniform, and its resistance to deformation is good. During cutting, composite processing, it is not prone to stretching or deformation, making it convenient for downstream processing into different forms of finished products. The hydrophilicity, softness, and weight can be adjusted as needed, suitable for various scenarios such as surface wipes, care pads, mask base fabrics, and disposable wiping materials.Ultimately, the sense of proportion of the soft and water repellent nonwoven fabric lies in this "failure": it allows liquids to pass through but does not make itself wet; it adheres to the skin but does not make its presence felt.Boulder was founded in 2007, with its headquarters located in Los Angeles, USA.
