Description

Preparation method of a control line for intelligent liquid transmission

technical field

The invention relates to the field of intelligent yarns, in particular to a method for preparing a control thread for intelligent liquid transmission.

Background technique

With the advancement of science and technology and the improvement of people's living standards, consumers' clothing concepts are changing, and their requirements for living environment and quality are getting higher and higher. Disposable sanitary products and functional clothing will soon become indispensable in people's daily life. On the other hand, with the development and progress of science and technology, human beings may get involved in harsher natural environments or artificial climate conditions, such as strenuous exercise, space exploration, polar expeditions, etc. The comfort puts forward higher requirements. The number of sports people in my country is expanding year by year, the rise of various new sports methods, and the holding of large-scale international sports events have greatly improved the enthusiasm of the people to participate in sports, and also stimulated the consumption of sportswear to a large extent. Although the current traditional maternal and child hygiene products can absorb body fluids (urine, blood, etc.), they will be concentrated in some areas and cannot effectively control the scattered or concentrated parts, which will affect comfort and even affect health; although some sportswear can achieve fast moisture absorption. Drying performance, the moisture absorption and quick-drying function has a limit bottleneck, for example, under a large amount of sweat, the moisture absorption and quick-drying function disappears, and there is also the problem of poor comfort.
