The invention relates to the technical field of fabric finishing agents, in particular to a cool feeling finishing agent.

Background

In hot summer, the human body is easy to sweat in a large amount due to the fact that the weather is hot. The common fiber fabrics have good air permeability, but still feel uncomfortable when a human body sweats a lot. In order to reduce the discomfort caused by high temperature by using cool articles, people use various natural summer sleeping mats, cool back cushions, cool seats, such as bamboo summer sleeping mats, bamboo seat cushions, and bamboo back cushions. The product has excellent cool feeling when being contacted instantly and is popular in the market. But do not have the soft body-fitting properties of textiles; inconvenient to carry and store; nor as a textile for apparel. Other types of cooling pads exist, but are not practical.

Also, the cool feeling is obtained by adopting compact spinning to reduce yarn hairiness, increase the surface smoothness of the fabric and reduce the warm-keeping effect. For example, chinese patent CN101906697A discloses a knitted fabric prepared by singeing mercerized yarn, and a contact cool fabric obtained by mercerizing again. For another example, chinese patent CN103132196A (application No. 201310031324.7) discloses a bedding fabric with antibacterial and cooling functions and its after-treatment, which is prepared by coating polyester filaments with chitin and flax fibers by a sirofil spinning process, and the cool feeling is obtained by reducing the surface hairiness of the fabric by spinning. However, the instant contact cool feeling and the lasting cool feeling of the cool clothes are not the same as those of summer sleeping mat products.
