Description
Technical Field
The invention relates to the technical field of textile materials, in particular to a liquid-fluid flexible linear material, a liquid-fluid composite yarn method and application.
Background
The definition of textile material is characterized by the tiny individual fibers, which are arranged and constructed into a material with practical structure, properties and shape by artificial means, utilizing the properties of the fibers. This artificial behavior can be applied to single fibers of small, slender, varying morphology and properties. Fluid materials such as water, oil, and non-newtonian fluids are generally considered to have properties such as ease of flow, compressibility, and viscosity, and are not effective for textile processing. However, the fluid material has a density higher than that of air and has a better resistance, so that the kinetic energy of the impacting object or bullet is quickly attenuated, and the damage condition of the impacted object is reduced.
Commercially available elastic fibers such as spandex (spandex), Lycra elastic (Lycra), dolastan elastic (Dorlastan), ilastan elastic (Elastane), DOWXLA (trade name), or rubber are typically incorporated into the fabric structure to impart elastic properties to these fabrics. The fiber fabric absorbs the energy of the projectile mainly through the deformation of the fibers so as to achieve the aim of reducing the impact. These fibers are elastic or thermoelastic and are destroyed when subjected to high temperatures, for example, they melt or disintegrate, resulting in a complete loss of the elastic properties of the fabric and the stability of the woven article. For this reason, elastic yarns are hardly used in fire-resistant fabrics; in addition, some protective woven sleeves for textiles have poor wear resistance and cutting resistance, and cannot effectively protect built-in articles, so that certain limitation exists in use.
The liquid flow material shows different properties according to the shear rheological capability, such as a solution with shear thickening rheological property, and excellent impact resistance, bulletproof property and the like; the emulsion fluid with the phase change function has excellent heat storage and temperature regulation functions and the like. At present, shear thickening materials are applied to protect human bodies, are mainly packaged into blocks or sheets and then sewn or inserted into human body clothes, are heavy, have overstaffed appearance, poor in air permeability and softness, and are limited in whole-area protection of organs and tissues of human bodies due to non-woven configurations of the shear thickening materials. Other liquid flow materials with the functions of rheology and phase change have similar technical problems. If the fluid material can be placed in the textile material to form the composite yarn, the deformation of the fluid material absorbs the energy of the projectile, so that the aim of reducing the impact is fulfilled, the protective performance of the textile is improved, the structures and the fiber distribution of the yarn and the textile are optimized and regulated, and the durability, the flame retardance and the like of the textile are greatly improved.
