High perfomance modification technologies provide us with special moisture manage fabrics. These fabrics have basic structural
components of animal and vegitable tissue utilised in manufactures,
representing the most perspective development in the field of protection against high temperatures, an open flame and thermal radiation. Special chemical fibers are the major achievement of the science and industry of termoregulating fabrics.
Such properties as high durability, thermo stability, chemical resistance, resistance to heat, incombustibility, electro conductivity, crashworthiness, ease, etc. make termoregulating fabrics and products based on them all are indespensable and irreplaceable in various industrial fields. The popularity of manage moisture fabrics grows day by day.
In respect of such uses, their
components divided for the sake of
classification into textile, paper-
making, brush and miscelaneous fibers.Thermo stability is basic property of high perfomance modification technologies in managing fabrics moisture. This type of fiber, on given parameter, surpasses known global analogues. Researche has shown that high perfomance modification technologies can provide us with fabrics that lose 40 % of durability only at 350°Ñ. The products of high perfomance modification technologies can be maintained as much as for a long time at temperatures 200-300°Ñ and is short-term at 400°Ñ.
The fiber possesses high hygroscopicity (equilibrium humidity of 12 %), and its ergonomic properties are close to those of cotton. High lengthening of a fiber allows to achieve high parameters of lengthening of fabrics, that finally increases service life of clothes, especially in extreme operational conditions. The parameter of fiber's oxygen index provides products' stability an open flame. Fabrics made of this fiber neither burn nor fuse. When choosing fabric produced out of the fiber, it is necessarily to look at a label.
The common characteristics of the
various forms of matter comprised in the widely diversified groups of
termoregulating fabrics are those of the colloids. Colloidal matter is intrinsically devoid of structure, and in the mass may be
regarded as homogenious; whereas
crystalline matter in its proximate
forms assumes definite and specific
shapes which express a complex of
internal stresses. The colloids show an infinite diversity of variations in these essential properties: certain of them, and
notably cellulose, maintain these
characterisrics throughout a cycle of transformations such as permit of their being brought into a soluble plastic form, in which condition they may be drawn into
filaments in continuous length. With the help of high performance
modification technologies lustra-
celluloses are produced, and have
already taken an established position as staple textiles.
Natural fabrics always were considered to be the best summer fabrics. They are strong, comfortable to wear, are easily washed, quickly dry, but also easily rumpled.People often choose silk for a summer dress. It is a 100 % natural material. All-wool fabrics are not so wear-resistant and besides strongly shrink at washing. The addition of viscose to high perfomance modification technologies' fibers makes fabric more massive, silky. It is well-draped, perfectly passes air, but easily rumpled. Lack is strongly showered on cuts of details. However, this fabric possesses good hygienic properties.
With the help of high perfomance
technologies fabrics obtain additional properties. If the structure of artificial or synthetic fabrics include lavsan, clothes are not rumpled, hold the form well, though less hygroscopic. Inclusio of acetate gives elasticity. You should remember that such fabric is hard and shrinks slitely at washing.
