Description

The present invention relates to a glove cloth having high grip, softness, and stretch recovery, and a textile product using the cloth.

Conventionally, natural leather, artificial leather, synthetic fiber suede and the like have been used for glove applications. However, although natural leather has excellent fit and grip, it has a problem in durability. On the other hand, although artificial leather and synthetic fiber suede have excellent durability, they have problems such as poor fit and grip.

As such a countermeasure, for example, Patent Document 1 proposes a cloth for gloves using ultrafine fibers called nanofibers. However, although such a glove fabric has sufficient grip, it is still insufficient for a fit like natural leather.
In addition, the glove cloth is required to have not only high grip but also softness and morphological stability.

The glove cloth of the present invention can be manufactured, for example, by the following manufacturing method. First, a sea-island type composite fiber (fiber for filament yarn A) formed of a sea component and an island component having a diameter of 10 to 1500 nm is prepared. As the sea-island type composite fiber, the sea-island type composite fiber (number of islands 100 to 1500) disclosed in JP-A-2007-2364 is preferably used.

In the sea-island type composite fiber composed of the above-mentioned sea component polymer and island component polymer, it is preferable that the melt viscosity of the sea component at the time of melt spinning is larger than the melt viscosity of the island component polymer. The diameter of the island component needs to be in the range of 10 to 1500 nm. At that time, if the shape of the island component is not a perfect circle, the diameter of the circumscribed circle is obtained. In the sea-island type composite fiber, the sea-island composite weight ratio (sea: island) is preferably in the range of 40:60 to 5:95, and particularly preferably in the range of 30:70 to 10:90.

Such a sea-island type composite fiber can be easily produced by, for example, the following method. That is, melt spinning is performed using the sea component polymer and the island component polymer. As the spinneret used for melt spinning, any spinneret can be used, such as one having a hollow pin group or a micropore group for forming an island component. The discharged sea-island type cross-section composite fiber is solidified by cooling air, preferably melt-spun at 400 to 6000 m / min, and then wound up. The obtained undrawn yarn is made into a composite fiber having desired strength, elongation, and heat shrinkage characteristics through a separate drawing step, or is taken up by a roller at a constant speed without being wound once, and subsequently drawn. It does not matter which method is used for winding after passing through.

Next, using the sea-island type composite fiber (fiber for filament yarn A) and, if necessary, filament yarn B, a woven or knitted fabric is commonly used so that the sea-island type composite fiber is exposed on the front surface and / or the back surface of the fabric. Weave and knit by. At that time, the sea-island type composite fiber and the filament yarn B may be contained in the woven or knitted fabric as a mixed fiber yarn, but the knitted fabric or the filament yarn B may be knitted or woven by interlacing or interweaving the sea-island type composite fiber and the filament B.

The number of layers may be a single layer, or may be two or more layers. Among them, when the fabric is a knitted fabric, the knitted fabric usually has elasticity, so that it is easy to fit the object and is preferable.

Next, the woven or knitted fabric (fabric) is treated with an alkaline aqueous solution, and the sea component of the sea-island type composite fiber is dissolved and removed with the alkaline aqueous solution to obtain the sea-island type composite fiber into a filament yarn A having a single fiber diameter of 10 to 1500 nm. By doing so, the cloth for gloves of the present invention can be obtained. At that time, as a condition for treating the alkaline aqueous solution, it is preferable to use a NaOH aqueous solution having a concentration of 3 to 4% and treat at a temperature of 55 to 65 ° C.

Further, the fabric may be dyed before and / or after the dissolution and removal with the alkaline aqueous solution. Calender processing (heat and pressure processing) or embossing may be performed. Furthermore, various functions such as conventional brushing treatment, water repellent treatment, UV shielding or antistatic agent, antibacterial agent, deodorant, insect repellent, phosphorescent agent, retroreflective agent, negative ion generator, etc. are imparted. Processing may be additionally applied.

Here, as the elongation ratio, in at least one of the vertical direction and the horizontal direction of the cloth (preferably in the vertical direction and the horizontal direction of the cloth), JIS L 1096-2010 8.16.1. It is important that the elongation rate by the D method is 13% or more (preferably 13 to 40%). If the elongation rate is less than 13%, a strong force is required to stretch the fabric, and a high fit may not be obtained.

Further, in the vertical or horizontal direction of the fabric (preferably in the vertical and horizontal directions of the fabric), JIS L 1096-2010 8.16.2. The elongation recovery rate by the D method is preferably 60% or more (more preferably 60 to 95%).

The flexural rigidity LH by the C method (loop compression method) is preferably in the range of 1.0 to 7.0 cN. When the bending hardness LH is larger than 7.0 cN, bending repulsion is strong and a soft texture may not be obtained. On the contrary, when the bending hardness LH is smaller than 1.0 cN, wrinkles may easily occur.

Next, the textile product of the present invention is selected from the group consisting of sports gloves, outdoor gloves, motorcycle gloves, work gloves, and precision work gloves, which are made of the above-mentioned glove cloth.
