Description

Knitted fabric containing silver fiber and manufacturing process thereof

The invention relates to the technical field of textiles, and relates to a knitted fabric, in particular to a knitted fabric containing silver fibers and a manufacturing process thereof.

Say

Background technique

With the progress and development of the times, the quality of human life has been greatly improved, and people's health awareness has also increased significantly. For related products in special occasions, such as diapers, sanitary napkins, insoles, sick suits and their sheets, the antibacterial and deodorant properties of the materials themselves are getting more and more popular.

Our concern.

With the increase in global average temperatures, especially in the summer, products with UV protection, such as parasols, are especially popular among young people.

In the prior art, although many products which are said to have the above functions have appeared, their practical effects are not satisfactory. Most of the sick clothes and their sheets can't stand the washing. Once after several times of washing, the antibacterial and deodorizing effects will be quickly reduced or even disappeared completely.

After a few rains, such as a parasol, its UV protection function is weakened until it disappears.

At present, the knitted fabrics containing silver fibers which have been disclosed in the market have not solved the above problems well. The reason is mainly because the existing knitted fabrics containing silver fibers are mostly coated with silver fibers. It can't be washed and rained. Therefore, the time to maintain its antibacterial, deodorant, anti-ultraviolet and other functions is limited, and the texture of the fabric is not soft, and the feel and wearing comfort are poor. Summary of the invention

The object of the present invention is to overcome the deficiencies or shortcomings of the prior art and to provide a silver fiber-containing material.
