Problems solved by technology

[0006] The above technologies all prepare jade into powder for blending and melt spinning. There is no mention of the technology of preparing jade into slurry and cellulose for solution blending and spinning, which causes particles to easily occur during the fiber spinning process. Agglomeration, resulting in clogged spinnerets and poor fiber spinnability
[0007] At the same time, the existing technical solutions are all adding jade materials to synthetic fibers; since synthetic fibers themselves do not have the characteristics of moisture absorption and perspiration of regenerated cellulose fibers, the cool feeling of the prepared fabrics is generally

Abstract

The invention provides jade cool regenerated cellulose fiber. The regenerated cellulose fiber contains 3.96-14.68% of jade. The invention further provides a method for preparing the jade cool regenerated cellulose fiber. The method comprises the step of preparing dispersion liquid. Dispersion liquid preparation comprises the steps of heating deionized water to 30-40 DEG C, adding a cellulose derivative dispersing agent, adjusting pH of aqueous solution to be 8-10 with sodium hydroxide, and then adding sodium dodecyl benzene sulfonate. The prepared jade cool regenerated cellulose fiber has remarkable fiber strength and the like. The prepared jade cool regenerated cellulose fiber contains a proper amount of jade, so that textiles prepared from the fiber have a pleasant cool feeling.

Description

technical field [0001] The invention relates to a regenerated cellulose fiber and a preparation method thereof, in particular to a jade cool regenerated cellulose fiber and a preparation method thereof, belonging to the technical field of textiles. Background technique [0002] With the rapid development of science and technology and the continuous improvement of people's living standards, people's requirements for clothing are not only to protect the body from the cold, but to pursue safety, comfort, beauty and more practical functions. In the hot summer, wearing cool and breathable clothes can not only improve the comfort of the body, but also bring people a good mood, which is beneficial to work and life. [0003] China has been known as the country of jade since ancient times. Jade is rich in minerals and trace elements that are beneficial to the human body. It is attached to the skin of the human body for a long time and released, which can improve blood microcirculat...
