Embodiment 1

[0060] Mix 200g of LaB as boride particles 6 Particles (specific surface area 30m 2 / g), 730g of toluene as dispersant and 70g of dispersant for dispersing microparticles, carry out dispersing process with media agitation mill, prepare 1kg of LaB 6 The dispersion liquid of fine particles is referred to as (liquid A). Then use a spray dryer to remove the toluene in (liquid A) to obtain LaB 6 Dispersible powder (A powder). The obtained (A powder) is added to polyethylene terephthalate particles as a thermoplastic resin, uniformly mixed with a stirrer, melted and kneaded with a twin-screw extruder, and the extruded strands (strand ) was cut into pellets to obtain LaB containing 30% by weight as a heat-absorbing component 6 Microparticle masterbatch. 30% by weight of the LaB are mixed in a weight ratio of 1:1 6 The microparticle polyethylene terephthalate masterbatch and the polyethylene terephthalate masterbatch without adding inorganic microparticles were prepared by the s...

Embodiment 2

[0062] Make the LaB that contains 10% by weight with the ratio of 1: 1.5 with the same method as Example 1 6 Microparticles and ZrO 2 Microparticle polyethylene terephthalate masterbatch. LaB 6 Microparticles and ZrO 2 The average particle diameters of the fine particles were observed to be 20 nm and 30 nm, respectively, by the dark field method using TEM. Multifilament yarns were produced in the same manner as in Example 1 using a masterbatch containing the above two fine particles. The obtained multifilaments were cut to produce polyester staple fibers, and staple yarns were produced in the same manner as in Example 1. Knitted articles are obtained using the spun yarn. Using the same method as in Example 1, the spectral properties of the fabricated woven product were measured, and the sunlight absorption rate was 43.38%. Furthermore, the temperature rise effect on the back side of the base fabric was measured by the same method as in Example 1. The result is shown in ...

Embodiment 3

[0064] The same method as in Example 1 was used to make CeB containing 30% by weight at a ratio of 1: 1.5. 6 Microparticles and ZrO 2 Microparticle polyethylene terephthalate masterbatch. CaB 6 Microparticles and ZrO 2 The average particle diameters of the microparticles were observed to be 25 nm and 30 nm, respectively, by the dark field method using TEM. Multifilament yarns were produced in the same manner as in Example 1 using a masterbatch containing the above two fine particles. The obtained multifilaments were cut to produce polyester staple fibers, and staple yarns were produced in the same manner as in Example 1. Knitted articles are obtained using the spun yarn. Using the same method as in Example 1, the spectral properties of the fabricated woven product were measured, and the sunlight absorption rate was 39.21%. Furthermore, the temperature rise effect on the back side of the base fabric was measured by the same method as in Example 1. The result is shown in ...

Abstract

A fiber capable of efficiently absorbs heat rays so as to have excellent warmth retaining property and further excelling in transparency so as to avoid any detriment to textile product designability; and a textile product from the fiber. Boride microparticles, a dispersion medium and a dispersant for microparticle dispersion were mixed together, dispersed and dried, thereby obtaining dispersion powder. The obtained dispersion powder was added to thermoplastic resin pellets, uniformly mixed together and kneaded in molten form, thereby obtaining a master batch containing heat ray absorption component. This master batch containing heat ray absorption component was mixed with a master batch prepared in the same manner except that no inorganic microparticles were added, melt spun and oriented, thereby obtaining a multifilament yarn. This multifilament yarn was cut into staples, from which a spun yarn having heat ray absorbing effect was produced. A knit product having warmth retaining property was produced from the spun yarn.

Description

technical field [0001] The present invention relates to fibers containing heat ray absorbing components and fiber products obtained by processing the fibers. Background technique [0002] In the field of fibers, fibers having various special functions are strongly desired. As one of them, there is fiber which gave heat retention. Generally, in order to improve the thermal insulation of fiber products, methods of thickening the texture, refining the mesh or increasing the color can be used. [0003] Patent Document 1 describes the technology of improving the thermal insulation properties of fibers by using heat-radiating fibers containing inorganic particles, wherein the inorganic particles are composed of one or more inorganic particles such as silica or barium sulfate, and have a thermal conductivity of 0.3. kcal / m 2 At least one of metals and metal ions above sec°C, and inorganic particles with heat radiation characteristics. [0004] Patent Document 2 describes that c...
