Embodiment 1

[0044] Fibers were prepared as follows:

[0045] (1) The emulsification includes adding shea butter to the emulsifier, heating up to 35° C., and stirring at 3500 rpm for 30 min to obtain a shea butter emulsion; the mass ratio of the shea butter to the emulsifier is 1:0.5, the emulsifier is a mixture of polyethoxylated isotridecanol and Tween 80, and the mass ratio of polyethoxylated isotridecyl alcohol to Tween 80 is 0.3:1;

[0046] (2) Mix a certain proportion of melamine and formaldehyde, add deionized water to stir and adjust the pH to 8.0, slowly raise the temperature to 65°C, and stir at 1000rpm for 30min to obtain a prepolymer;

[0047] (3) Add the prepolymer prepared in step (2) dropwise to the shea butter emulsion prepared in step (1), while applying stirring with a rotating speed of 1300rpm, while adjusting the temperature to 60°C and adjusting the pH to 6.0, stir for 2 hours, add sodium methylene bis-naphthalene sulfonate to obtain microcapsule liquid;

Abstract

The invention discloses a regenerated cellulose fiber containing shea butter, and a preparation method thereof. The regenerated cellulose fiber comprises the emulsified shea butter and zinc-containingsunscreen factors. After a person wears fabric made of the regenerated cellulose fiber for 2 hours, the moisture content of the stratum corneum of the skin can be increased by 5-9.5%. The UPF (ultraviolet protection factor) of the fabric made of the regenerated cellulose fiber is not smaller than 60, and the UVA (ultraviolet A) transmittance is smaller than 3.5%. The regenerated cellulose fiber containing the shea butter has a good skin moisturizing effect, and the moisture content of the stratum corneum of the human skin can be increased after the fabric is worn for a certain time; the few sunscreen factors are added into the fiber to interact with latex materials in the shea butter, and accordingly, the sunscreen performance of the fabric made of the fiber is improved greatly.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a regenerated cellulose fiber containing shea butter and a preparation method thereof. Background technique [0002] With the improvement of people's quality of life, there is a huge consumption desire for fiber textile products, especially the skin-friendly and functional requirements of fiber products. Among them, fiber products with moisturizing function are more concerned by the market. [0003] In moisturizing functional products, the excellent effect 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 substances. Among them, the content of triglyceride is about 80%, and the content of unsaponifiable matter varies according to the season, place of origin, extraction and refining methods. Some of the...
