Problems solved by technology

Although this technical solution provides microcapsule protection measures for functional substances, so that the spinning process can be carried out effectively; it also ignores that during the use of fibers, functional substances cannot play an effective anti-ultraviolet effect because they are always isolated.
[0008] It can be seen from the above examples that functional materials are often more lively in nature, and are easily lost under the action of high temperature and high pressure in spinning and post-processing, acid, alkali and other treatment agents.
After the functional materials are protected by microcapsules and other methods, although the functional materials can be guaranteed to be protected during spinning and post-processing, the functional materials are isolated from the outside world by the microcapsule wall material during the use of the treatment. Open, can not play the expected role
[0009] In summary, there is no precedent for using removable shell materials for functional fibers in the prior art

Abstract

The invention relates to a fiber containing a compound functional microcapsule with a removable shell. The fiber contains the compound functional microcapsule with the removable shell, a core of the microcapsule comprises a thermosensitive material and a second functional material, and the shell of the microcapsule comprises removable materials. The functional material of the fiber containing thecompound functional microcapsule with the removable shell can be effectively protected in spinning and subsequent processing procedures, and the fiber is simple, economical, less in equipment transformation and easy to produce in batch.

Description

technical field [0001] The application relates to a fiber containing composite functional microcapsules with removable shell materials, which is suitable for the technical field of fiber composite materials. Background technique [0002] Fiber is the most common and one of the most important basic materials in production and life. Fiber plays a pivotal role in textiles, light industry, petroleum, national defense, metallurgy, biology, medicine and other fields. In the field of textiles alone, fibers are widely used in various types of underwear, textiles, clothing, non-woven fabrics, etc. At the same time, fiber materials are excellent functional carriers with various functions, such as mechanics, optics, heat, and electricity. Functional fibers are playing an increasingly important role in industrial production and daily life. [0003] After mixing functional substances, such as nanoparticles, with fiber raw materials (such as various polymer solutions or melts), they pas...
