Definitions

  • the present invention relates to a modified cross-section fiber excellent in cooling feeling. More specifically, the present invention relates to an atypical cross-section fiber excellent in cooling feeling that can be suitably used for apparel use, which is excellent in comfort and texture when worn in summer.
  • Patent Document 1 those using a hygroscopic polymer as a polymer constituting the fiber (Patent Document 1), those using a thermoplastic elastomer (Patent Document 2), and inorganic particles having excellent thermal conductivity are kneaded. Something has been proposed.
  • hygroscopic polymers cause stickiness during sweating and cause discomfort
  • elastomers have inferior processing characteristics such as low dyeing fastness in addition to their own tackiness.
  • Patent Document 5 a mixed yarn having water absorption and hygroscopicity using a fiber having a flat cross section as a sheath yarn has been proposed (Patent Document 5).
  • the mixed yarn is intended to reduce the feeling of stickiness by reducing the chance that the core that retains the moisture transferred through the gap between the fibers of the flat cross section reduces contact with the skin. This method is not different from the method using the hygroscopic polymer in that processing is employed.
  • the object of the present invention is made in the background of the above-mentioned conventional technology, and the object is to provide an atypical cross-section fiber that exhibits excellent cold contact feeling and texture when made into a fabric and is excellent in workability. .
  • the present inventors have found that the above object can be achieved by specifying a polymer that forms a fiber in a modified cross-section fiber, and have reached the present invention.
  • a fiber having polyethylene as a main component the cross-section perpendicular to the fiber axis of the fiber is a flat shape, and the width A of the long axis of the flat cross-section and a short width perpendicular thereto.
  • An atypical cross-section fiber excellent in cooling sensation characterized in that the ratio A / B1 of the maximum shaft width B1 is 2 to 10.
  • an atypical cross-section fiber excellent in processability which can express an excellent cooling feeling and texture when used as a fabric.
  • A represents the width of the long axis in the fiber cross section
  • B1 represents the maximum width of the short axis perpendicular to it.
  • A represents the width of the long axis in the fiber cross section
  • B1 represents the maximum width of the short axis perpendicular to it
  • B2 represents the minimum width of the short axis corresponding to the constricted portion.
  • the atypical cross-section fiber of the present invention needs to have polyethylene as a main constituent.
  • the polyethylene is large and is classified into high-density polyethylene, linear low-density polyethylene, and low-density polyethylene, and among these, high-density polyethylene is preferable because it has good yarn production and high thermal conductivity.
  • the polyethylene is preferably composed of a single component, but a C3 to C12 higher alkene may be contained as a copolymer in a proportion of less than 5% by weight.
  • the polymer used for the fiber of the present invention may contain conventionally known antioxidants, light-proofing agents, flame retardants, pigments and the like as long as the object of the present invention is not impaired.
  • the atypical cross-section fiber of the present invention has a flat cross-sectional shape so that the contact area with the skin can be effectively increased and a cool feeling of contact can be sufficiently felt when the cloth for clothing is used. It is necessary.
  • the ratio A / B1 between the width A of the major axis of the flat shape and the maximum width B1 of the minor axis perpendicular to the major axis needs to be 2 to 10. If the ratio A / B1 of the width A of the major axis and the maximum width B1 of the minor axis perpendicular to it is less than 2, it becomes close to a round cross section and the effect of the flat shape is reduced, while if it exceeds 10, the effect of the flatness is reduced. In addition to the above, the process stability during yarn production may be reduced. A particularly preferred range is 3-8.
  • the cross-sectional shape of the modified cross-section fiber of the present invention is a shape in which round cross-section single yarns are linearly connected in the major axis direction of the cross section, and a shape having 2 to 5 constricted portions is more preferable.
  • the circular cross-section single yarns are linearly connected and the overall flat cross-sectional shape reduces the space between the single yarns compared to the case where the single round cross-section yarns exist alone, effectively expressing the cooling effect.
  • the bending properties of the fibers are improved, and the fabric is rich in flexibility.
  • the cross-sectional shape of the fiber is not a mere flat shape, but has a constricted portion, for example, without excessively relying on the reflection of inorganic compound particles, thereby improving the irregular reflection on the fiber surface and the light refraction effect, thereby preventing permeation. It is possible to impart a certain degree of property. If the number of constricted portions is less than 2, the above effect is difficult to obtain, and conversely if the number of constricted portions exceeds 5, it is not preferable in terms of process stability.
  • the ratio A / B1 between the long axis width A of the flat cross section and the maximum width B1 of the short axis perpendicular thereto is 2-6.
  • the flatness ratio is less than 2, the effect of the flat cross section is difficult to obtain, and in the case of a fabric such as a woven or knitted fabric, the long axis is difficult to be arranged parallel to the fabric surface, and the heat shielding property may be lowered.
  • the flatness ratio exceeds 6, the spinning stability is lowered, so a more preferable range is 3-5.
  • the ratio B1 / B2 between the shortest maximum width B1 of the flat cross section and the shortest axis minimum width B2 corresponding to the constricted portion is 1.05 or more and 1 .6 or less is preferable.
  • B1 / B2 is less than 1.05, the effect of connecting the above-described round cross sections may be reduced, and when B1 / B2 exceeds 1.6, the thickness of the connecting portion (constriction portion) becomes thin, The cooling effect may be reduced.
  • a preferred range is 1.1 to 1.4.
  • the single yarn fineness of the modified cross-section fiber of the present invention is preferably 1 to 10 dtex.
  • the single yarn fineness is less than 0.1 dtex, the spinning stability is lowered, and the fine voids between the fibers are increased, the heat insulation between the fibers is increased, and the cooling effect may be reduced.
  • the single yarn fineness exceeds 10 dtex, when the knitted fabric is used, the inter-fiber distance is increased, the contact area is decreased, the contact cooling effect is lowered, and the texture may be hardened.
  • the single yarn fineness is more preferably 0.5 to 8 dtex.
  • the strength of the modified cross-section fiber of the present invention is preferably 1.5 cN / dt or more. If the strength is less than 1.5 cN / dt, the durability is poor.
  • a known method may be used, but the melt spinning method is preferable in terms of cost.
  • the stretching method known hot roll stretching or warm water stretching can be used.
  • a known antistatic agent, fiber finishing agent, or the like can be used as necessary in the process of spinning and stretching the fiber.
  • the modified cross-section fiber of the present invention when used as a fabric, it may be used for all fabrics or partially.
  • the structure is not particularly limited, and may be a woven fabric, a knitted fabric, or a non-woven fabric.
