Abstract

The invention discloses a regenerated cellulose fiber containing shea butter and a preparation method thereof. The regenerated cellulose fiber includes emulsified shea butter, and the fabric made of the regenerated cellulose fiber can increase The moisture content of the stratum corneum of the skin is 5-9.5%; the regenerated cellulose fiber also includes a sunscreen factor containing zinc, the UPF of the fabric made of the regenerated cellulose is not less than 60, and the transmittance to UVA is less than 3.5%. The regenerated cellulose fiber provided by the present invention contains shea butter, which has good skin moisturizing effect, and can increase the water content of the stratum corneum of human skin after wearing for a certain period of time; at the same time, a small amount of sunscreen factor is added to the fiber, and the sunscreen The factor acts synergistically with the latex substance in the shea butter, which greatly improves the sunscreen performance of the fabric made of the fiber.

Description

technical field [0001] The invention belongs to the technical field of textiles, and specifically relates to a kind of regenerated cellulose fiber containing shea butter and a preparation method thereof. Background technique [0002] With the increasing quality of people's life, there is a huge willingness to consume fiber textile products, especially the skin-friendly and functional fiber products have certain requirements. Among them, fiber products with moisturizing function are more concerned by the market. [0003] Among moisturizing functional products, the excellent effects and skin-friendly properties of shea butter are increasingly recognized and accepted by consumers. The main components of shea butter are triglyceride (containing a certain amount of linoleic acid) and unsaponifiable compounds. Among them, the content of triglyceride is about 80%, and the content of unsaponifiable matter varies with seasons, places of origin, and extraction and purification methods...
