The analysis table 1 shows that the cross-sectional shape of the polyester is replaced by a circular shape, which results in the best heat preservation rate of the fabric, and the comparison between the example 5 and the comparative example 1 shows that the cross-sectional shape of the dumbbell-shaped polyester can well achieve the heat preservation effect, because the dumbbell-shaped polyester has a better mechanical structure and can ensure that air can be reserved inside the dumbbell-shaped polyester after extrusion to form an air layer, which achieves the excellent heat preservation effect, but after the circular cross-sectional polyester is easily extruded with each other in the spinning process, no yarn gap exists between fibers, and therefore, the common polyester in the market cannot achieve the excellent heat preservation effect.
In summary, the polyester, the acrylic fiber and the natural fiber are mixed, the advantages of high breaking strength and elastic modulus of the polyester, moderate rebound resilience, excellent heat setting effect and good light resistance are combined, the acrylic fiber is soft, bulky, easy to dye, bright in color, light-resistant, antibacterial and mothproof, the characteristics of non-uniform length and fineness, good hygroscopicity and meltresistance, low strength and elongation capability, good antistatic property and the like of the natural fiber are combined, and the obtained yarn can be combined with various advantages and has the advantages of heat preservation, good elasticity, softness, dilution and the like.
In addition, through years of research, the inventor selects and uses the polyester with the dumbbell-shaped cross section as a raw material, the polyester with the cross section can have a better mechanical structure, and after extrusion, the air can be kept in the polyester, so that an air layer is formed, and a superexcellent warm-keeping effect is achieved.
In addition, the polyester fiber, the acrylic fiber and the natural fiber are only selected as raw materials, so that the polyester fiber, the acrylic fiber and the natural fiber are low in price, suitable for popularization, excellent in heat retention and wide in application range.
The spinning process can be used for industrial large-scale production, develops the yarn with softness, comfort, moisture absorption, quick drying and excellent heat preservation performance, fills the market blank and is worthy of popularization.
The embodiments described above are some, but not all embodiments of the present application. The detailed description of the embodiments of the present application is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
