Hydrophilic non woven fabric is a multipurpose material used in manufacturing hydrophilic products. These fabrics are water-repellent, yet do not stimulate the human body or cause allergic reactions. Therefore, they are ideal for sanitary napkins and sanitary wipes for women and children. These nonwoven fabrics are available in paper tubes and are sold all over the world.
These fabrics are made of polyolefin and hydrophilic agent. The hydrophilic agent is contained in the polyolefin as one compounded mixture. This is easily verified by treating a nonwoven fabric with water. The reduced surface tension of water indicates that the hydrophilic agent has been coated onto the fabric. The reduction in surface tension means that the hydrophilic agent is able to dissolve water in an intense state. The surface tension of water is usually around 70-72 mN/m.
The hydrophilic nonwoven fabric of the present invention is also heat-resistant, which means that it retains its hydrophilicity after being heated. The heating process may include heat embossing or a dry process. Despite these drawbacks, the hydrophilicity of the hydrophilic nonwoven fabric can still be revealed after these processes.
Hydrophilic nonwoven fabric is a versatile material that is used in medical and hygienic materials. Many different sanitary products are made from hydrophilic nonwoven fabric. In addition to being hygienic, these fabrics are also environmentally friendly. Sometimes, it is necessary to use an adhesive glue to adhere the fabric together.
