Description

  The present invention relates to a fabric having not only flame retardancy but also excellent stretchability and fabric strength, and a fiber product using the fabric.

  Conventionally, flame retardant fabrics are used as work clothes worn by people engaged in work that may be exposed to flames such as fire fighting, 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.

  In order to impart stretchability to the fabric using the flame retardant fiber, a method using an elastic yarn (see, for example, Patent Document 1, Patent Document 2, and Patent Document 3) or heat setting after twisting the flame retardant fiber A twisting method (see, for example, Patent Document 4, Patent Document 5, and Patent Document 6) has been proposed.

  However, fabrics using elastic yarn have problems such as normal use due to low heat resistance, flame retardancy, chemical resistance, especially chlorine resistance, and a sudden drop in stretchability during washing. In addition, it was not satisfactory in terms of fabric strength.

  On the other hand, in the fabric using the flame-retardant fiber that is heat-set after twisting and then untwisting, there is a problem that the stretchability is lowered during weaving, post-processing steps and wearing, and sufficient performance and quality as a fabric cannot be obtained. There was a problem of high costs.

In the spun yarn, the total fineness may be appropriately selected in consideration of the surface appearance, heat resistance, thermal protection, stretchability, texture, and the like according to the use. In particular, the fineness of the spun yarn is 58 dtex (English cotton A range of 100 count single yarn) to 580 dtex (corresponding to 10th cotton count) is preferable.
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 where good spinning process passability and flexibility are required.

In the spun yarn, the twist coefficient K is preferably in the range of 2.5 to 4.5 from the viewpoint of physical properties and flexibility of the fabric. However, T = K√n, T is the number of twists per inch (2.54 cm), n is an English cotton count, and K is a twist coefficient.
The spun yarn may be a single yarn or a twin yarn.

  In the present invention, the composite fiber is a composite fiber in which two components are bonded in a side-by-side type or an eccentric core-sheath type. The composite yarn contained in the fabric of the present invention includes not only the above-mentioned spun yarn but also the composite fiber, so that the composite fiber takes the form of a three-dimensional coil crimp in the heat treatment step of the fabric, and the composite yarn has elasticity. As a result, stretchability is also imparted to the fabric.

  Here, examples of the two components forming the composite fiber include combinations of polyester / polyester, polyester / nylon, and the like. More specifically, combinations such as polytrimethylene terephthalate / polytrimethylene terephthalate, polytrimethylene terephthalate / polyethylene terephthalate, and polyethylene terephthalate / polyethylene terephthalate are preferable. At that time, it is preferable to make the intrinsic viscosities different from each other. Moreover, you may contain additives, such as antioxidant, a ultraviolet absorber, a heat stabilizer, a flame retardant, a titanium oxide, a coloring agent, and an inert fine particle.

  In the composite fiber, the shape of the fiber is not particularly limited, and may be a long fiber (multifilament) or a short fiber, but a long fiber (multifilament) is preferable for obtaining excellent stretchability.

  The total fineness and single fiber fineness of the composite fiber are appropriately selected according to the application, and the total fineness is preferably 20 to 200 dtex and the single fiber fineness is preferably 0.5 to 10.0 dtex.

  In the present invention, the composite yarn includes the spun yarn and the composite fiber.

Is preferably in the range of 4 to 30% by weight, particularly preferably 4 to 20% by weight.

  In the composite yarn, the composite method is not particularly limited, but is preferably a twisted yarn or a covering yarn. More specifically, it is preferable to use the above-described spun yarn and composite fiber to perform twisting or covering using a commercially available up twister, covering machine, italic twisting machine, double twister or the like. At that time, the twist set may be implemented according to the required quality. The twist set for the composite twisted yarn can be a vacuum steam set used for a set of ordinary spun yarn. The temperature at the time of setting the composite twisted yarn is preferably in the range of 50 to 95 ° C (more preferably 50 to 85 ° C). If the twist set temperature of the composite twisted yarn is too high, the stretchability of the finally obtained fabric may be impaired.

  The stretchable flame retardant 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 important that the weight ratio of the flame retardant fiber is in the range of 75% by weight or more (preferably 75 to 95% by weight) with respect to the fabric weight. . In this case, the weight ratio of the non-flame retardant fiber is less than 25% by weight. When the weight ratio of the flame retardant fiber is less than 75% by weight, the flame retardancy may be lowered, which is not preferable.

In addition, it is important that the weight ratio of the composite fiber is in the range of 5 to 15% by weight with respect to the fabric weight. When the weight ratio of the composite fiber exceeds 15% by weight with respect to the fabric weight, it is not preferable because the flame is easily transmitted along the composite fiber and easily combusted. On the other hand, when the weight ratio of the composite fiber is less than 5% by weight, the stretchability of the fabric may be lowered, which is not preferable.

  The fabric structure of the fabric is not particularly limited, but is preferably a woven fabric or a knitted fabric. In the case of a woven fabric, a plain structure, a twill structure, a satin structure, and ripstop of each structure are exemplified. Examples of the knitted fabric include machine knitting, crochet knitting, stick knitting, Afghan knitting, and lace knitting. For example, in the case of a woven fabric, the total amount of the composite yarn may be arranged in the warp direction and / or the weft direction, and the spinning and the composite yarn may be, for example, 1: 1, 2: 1, 3: They may be arranged at an arrangement ratio of 1, 1: 2, 1: 3. The method for knitting and weaving is not particularly limited, and a method using a normal knitting machine or loom may be used.

  Next, by subjecting the fabric to heat treatment such as refining, relaxing, dyeing, and setting, the composite fiber in which the two components contained in the fabric are bonded to the side-by-side type or the eccentric core-sheath type is subjected to three-dimensional coil crimping. It takes a form and gives stretchability to the fabric.

  Various kinds of functions such as water absorption processing, water repellent processing, brushed processing, flame retardant processing, ultraviolet shielding or antibacterial agent, deodorant agent, insect repellent agent, phosphorescent agent, retroreflective agent, and negative ion generator are imparted to the fabric. Processing may be additionally applied.

  Since the fabric thus obtained contains the composite yarn, it has not only flame retardancy but also excellent stretchability and fabric strength.

  Here, it is important that the tensile strength of the fabric measured by the JIS L1096: 2010 A method is not less than 850 N (preferably 850 to 1200 N) and not less than 600 N (preferably 600 to 1000 N). In the fabric, the tear strength measured by the JIS L1096: 2010 D method is preferably 50 N or more (more preferably 60 to 120 N) and 50 N or more (more preferably 50 to 100 N). In order to improve the strength (tension or tear) of the fabric in this manner, it is preferable to include para-aramid fibers in the spun yarn.

  Further, as the stretchability of the fabric, it is preferable that the elongation in the warp direction and / or the weft direction is in the range of 3 to 50%. The stretch recovery rate of the fabric is preferably 70% or more (more preferably 73 to 99%) in the warp direction and / or the weft direction. Moreover, as a flame retardance, it is preferable that the limit oxygen index measured by JISK7201 is 25 or more (more preferably 25-40) in a fabric. The afterflame time is preferably 1.5 seconds or less, the residual time is preferably 1.5 seconds or less, and the carbonization length is preferably 8.0 cm or less, as measured according to JIS L1091 A-4 method appendix 8.

  Next, the textile product of the present invention is formed using the above-mentioned fabric. Since such a fabric uses the above-mentioned fabric, it is excellent in stretchability and flame retardancy and fabric strength. Such textile products include fire clothes, fire clothes, office clothes, motorsport racing suits, work clothes, gloves, hats, vests, various industrial materials (sheets, tents, membrane materials, hoods, building materials, housing materials, vehicles, etc.) Interior materials). The work clothes include work clothes for ironworks and steel factories, work clothes for welding work, work clothes in an explosion-proof area, and the like. The gloves include working gloves used in the aircraft industry, the information equipment industry, the precision equipment industry, etc. that handle precision parts.

Next, although the Example and comparative example of this invention are explained in full detail, this invention is not limited by these. In addition, each measurement item in an Example was measured with the following method.
