Abstract
The invention relates to antibacterial Lycra fabrics. The lycra fiber of the fabrics contains nano-silver microcapsules whose shells are polymers of chitosan and arabic gum and cores are made of nano-silver. Nano-silver capsules are loaded on the lycra fabrics so that the fabrics with antibacterial activity are obtained.
Description
Technical field
The invention belongs to textile material preparation field, be specifically related to a kind of antibacterial Lycra fabric.
Background technology
Lycra (LYCRA) freely can elongate 4 to 7 times, and after external force release, replys original length rapidly.It not can be used alone, and artificial or natural fabric can interweave and uses with any other.It does not change the outward appearance of fabric, is a kind of invisible fiber, greatly can improves the performance of fabric.
Along with development, the growth in the living standard of human sciences's technology; people are to attention that is healthy and environmental protection; new requirement be there has also been to fabric; namely focus on fabric attractive in appearance and comfortable while; the function such as the feature of environmental protection and wholesomeness of fabric is had higher requirement; therefore Multifunction fabric will become an important new industry field, and to have the antibacterial functions eliminated peculiar smell, prevent bacteria breed and reduce skin infectious disease function be one of development trend of fabric.
And Lycra fabric can not meet people to requirement while comfortable, antibacterial, healthy three aspects, a kind of antibacterial Lycra fabric is urgently developed in this area.
Summary of the invention
An object of the present invention is to provide a kind of antibacterial Lycra fabric, and containing Nano Silver microcapsules on the Lycra fiber of described fabric, the housing of described Nano Silver microcapsules is the condensate of shitosan and Arabic gum, and nucleome is Nano Silver.
