Description

TECHNICAL FIELD The present invention relates to a stretch fabric having flame retardancy, stretchability and high antistatic properties, and a textile product using the stretch fabric.

BACKGROUND ART Conventionally, flame-retardant fabrics have been used as work clothes worn by people engaged in work that may be exposed to fire, such as firefighting, electric power, and chemical companies. This flame-retardant fabric mainly uses flame-retardant fibers such as meta-aramid fibers and para-aramid fibers, and it is generally considered difficult to impart stretchability to the fabric.

As a stretch fabric using conventional aramid fibers, Patent Document 1 discloses a flame-retardant fabric using a spun yarn in which aramid fibers, other fibers, and antistatic fibers are blended, and a plied yarn in which stretchable fibers are fused and twisted. Stretch fabrics have been proposed. However, although stretchability and pilling resistance have been improved in conventional stretch fabrics, there is still room for further performance improvements, such as flame retardancy and antistatic properties, to meet market demands.

The spun yarn preferably consists of only the above flame-retardant fibers, but may contain non-flame-retardant fibers (fibers having a limiting oxygen index of less than 25 as measured by JIS K7201). Examples of non-flame-retardant fibers include polyester fibers, nylon fibers, rayon fibers, polynosic fibers, lyocell fibers, acrylic fibers, vinylon fibers, cotton, hemp, and wool. One or more of these non-retardant fibers can be used.

These non-retardant fibers contain additives such as antioxidants, ultraviolet absorbers, heat stabilizers, flame retardants, titanium oxide, coloring agents, inert fine particles, conductive particles, etc., to the extent that they do not impair the purpose of the present invention. may contain.

The fiber length of flame-retardant fibers and non-flame-retardant fibers is preferably in the range of 35 to 110 mm.

In addition, the total fineness of the spun yarn may be appropriately selected in consideration of the surface appearance, heat resistance, thermal protection, stretchability, texture, etc., depending on the application. It is preferably in the range of 580 dtex (corresponding to 10 count of British cotton) to 580 dtex (corresponding to 100 count single yarn).

In addition, the single fiber fineness of the spun yarn is preferably in the range of 0.6 to 5.5 dtex from the viewpoint of use in clothing applications that require good passing through the spinning process and flexibility.

The twist coefficient K of the spun yarn is preferably in the range of 2.5 to 4.5 from the viewpoint of the physical properties and flexibility of the fabric. where T=K√n, where T is the number of twists per inch (2.54 cm), n is the British cotton count, and K is the twist factor.

Also, the spun yarn may be a single yarn or a two-ply yarn. Moreover, additives such as antioxidants, ultraviolet absorbers, heat stabilizers, flame retardants, titanium oxide, colorants, and inert fine particles may be contained.

The shape of the stretchable yarn of the present invention is not particularly limited, and may be long fibers (multifilaments) or short fibers, but long fibers (multifilaments) are preferred for obtaining excellent stretchability. Stretchable yarns are preferably stretchable nylon fibers, polyester fibers, or polyurethane fibers, and particularly preferably ether-based polyurethane.

The conductive yarn of the present invention is not particularly limited in fiber shape, and may be either long fibers (multifilament) or short fibers, but long fibers (multifilament) are preferred for obtaining excellent stretchability. The conductive thread may be a fiber having conductivity, and examples thereof include fibers containing carbon particles/fibers and metal particles/fibers.
The total fineness and single fiber fineness of the stretchable yarn and conductive yarn are appropriately selected according to the application, preferably in the range of 20 to 200 dtex for the total fineness and 0.5 to 10.0 dtex for the single fiber fineness.

Although the method of combining the composite yarn of the present invention is not particularly limited, it is preferably a plied yarn or a covering yarn. More specifically, the spun yarn and the composite fiber are preferably plied or covered using a commercially available up twister, covering machine, Italian twister, double twister, or the like. At that time, the twist setting may be performed according to the required quality. Vacuum steam setting, which is used for setting ordinary spun yarns, can be used for twist setting of the composite plied yarn. The temperature at which the composite plied yarn is set is preferably in the range of 50 to 80°C (more preferably 65 to 75°C). If the twist setting temperature of the composite plied yarn is too high, the stretchability of the finally obtained fabric may be impaired.

The stretch fabric of the present invention is a fabric using such a composite yarn. At that time, in order to obtain excellent flame retardancy, it is essential that the weight ratio of the flame-retardant fiber is in the range of 40% by weight or more (preferably 70 to 95% by weight) with respect to the weight of the fabric. If the weight ratio of the flame-retardant fiber is less than 40% by weight, the flame retardancy may be lowered, which is not preferable.

Also, it is essential that the weight ratio of the fibers of the stretch yarn is in the range of 5 to 15% by weight with respect to the weight of the fabric. If the weight ratio of the fibers of the stretchable yarn exceeds 15% by weight with respect to the weight of the fabric, the flame tends to propagate along the composite fiber, which is not preferable because it tends to burn. Conversely, if the weight ratio of the fibers in the stretch yarn is less than 5% by weight, the stretchability of the fabric may decrease, which is not preferable.

Although the fabric structure of the fabric is not particularly limited, it is preferably woven or knitted. In the case of woven fabrics, plain weave, twill weave, satin weave, and ripstop of each weave are exemplified. Knitted fabrics include machine knitting, crochet knitting, needle knitting, Afghan knitting, and lace knitting.

The knitting and weaving method is not particularly limited, and a method using a normal knitting machine or loom may be used. By arranging the conductive flame-retardant plied yarn in this manner, high antistatic properties can be obtained. If the pitch exceeds 50 mm, the antistatic property is lowered, which is not preferable.

The fabric is subjected to heat treatment such as singeing, refining, relaxing, dyeing, and setting. Fabrics are treated with various functions such as water absorption, water repellent, raised, flame retardant, UV shielding, antibacterial agents, deodorants, insect repellents, phosphorescent agents, retroreflective agents, negative ion generators, etc. may additionally be applied.

The stretchability of the fabric is preferably in the range of 5 to 40% (more preferably 5 to 20%) in the warp and/or weft direction. In addition, as for the elongation recovery rate of the fabric, it is preferable that the elongation recovery rate in the warp direction and/or weft direction is 70% or more (more preferably 73 to 99%).

The flame retardancy of the fabric is preferably such that the limit oxygen index measured according to JIS K7201 is 25 or more (more preferably 25 to 40).

The pilling of the fabric preferably has a grade of 3.0 or higher (more preferably 3.5 or higher) as defined by JIS L1076 A method (ICI 10 hr).

The antistatic property (charge amount) of the fabric is 6 microcoulombs or less (more preferably 4.0 microcoulombs or less, particularly preferably 3.0 microcoulombs or less) as defined by JISL1094 C method. is preferred.

Next, the textile product of the present invention is made by using the above fabric. Since such a textile product uses the above fabric, it is excellent in stretchability and flame retardancy.
