Can we say the same about the future of the mass of fibers? A few years ago led to talk about himself spandex fiber, are of great interest to general consumers. Its main advantage – a very large elasticity. Spandex fiber can be stretched like rubber – in 5-6. And, very importantly, this extension is completely reversible. Above all, the strength of the synthetic fibers are several times higher than that of rubber. Spandex fiber immediately began to be used instead of rubber thread, in production of tires, garters, swimwear and other mass products? There are no words for such material – a big success. Yet the production of spandex fiber and other fibers s less interesting, intended for public use, will never reach not just hundreds, but many tens of thousands of tons per year. Either way, their scope is limited considerably.
Thus, in the coming years can hardly expect new chemical fiber mass application. The main direction of research in this area, a significant improvement in the properties of already known species. So, in my opinion, should be asked about the future of science and chemical fiber industry, posed at the beginning of the article. And now, on how to change the properties of existing materials. We'll talk about the structural and chemical modifications. Control the structure of fibers can be in two ways. For example, molding or stretching the fiber allows to regulate a wide range of its mechanical properties, particularly strength and deformation resistance, repeated many times.
By varying the conditions of molding IPI degree of stretching, you can change the size and orientation of the individual elements of the supramolecular fiber structure, regulate the uniformity of the structure. This is – one way. The second variant of structural modifications – restructuring macrostructure. If you change, for example, the terms of the twist yarn, then change the properties of "e single elementary fiber, and the entire twisted yarn consisting of a large number of such filaments.
