It is considered that this is because as the diameter of the convex portion becomes larger, the groove-like concave portion which becomes the starting point of bending decreases.
  • FIG. 6A The electron micrograph (100 times) which shows the cross section of the palm side of the non-slip glove which formed the NBR foaming layer of the comparative example 4 is shown to FIG. 6A. Moreover, the electron micrograph (100 times) which shows the cross section of the convex part of the anti-slip glove of Example 4 is shown in FIG. 6B, and the electron micrograph (100 times) which shows the cross section of the recessed part of the anti-slip glove of Example 4. It is shown in FIG. 6C.
  • the pore diameter of the cells is large and the cell walls (intervals of cells) are thick. This is considered to be because each cell was formed independently by stirring with a hand mixer to mechanically foam NBR. Further, it can be seen that the NBR is not impregnated up to the inner surface side of the glove body (base fabric).
  • the hole diameter of a cell is various in size, and there are many fine cells in the surface side.
  • the cell extends entirely to the inner surface side of the glove body (base fabric), and the cell wall is thinner compared to FIG. 6A.
  • the gloves of Examples 1 to 11 can exhibit higher moisture permeability as compared with the glove of Comparative Example 4.
  • the graph of FIG. 7 shows the relationship between the convex portion occupancy rate and the moisture permeability.
  • the measurement result of the Example and comparative example from which only the recessed part occupancy rate of the press board used in the case of press processing differs is shown.
  • the moisture permeability in Examples 1 to 5 and Comparative Examples 1 and 2 is shown.
  • the moisture permeability improves as the convex portion occupancy rate increases.
  • the convex portion occupancy rate is about 80%, a non-slip glove having a very high moisture permeability similar to the glove of Comparative Example 2 which is not pressed can be obtained.
  • the convex portion occupancy rate is 50%, a non-slip glove having high moisture permeability comparable to the glove of Comparative Example 2 can be obtained.
  • the convex portion occupancy rate is 30% or more, high moisture permeability of 6000 g / m 2 ⁇ 24 h or more can be expressed, and a non-slip glove having sufficient moisture permeability can be obtained.
  • Example 4 changing the angle by which the concavo-convex plate used at the time of press processing is pressed against the flat-typed woven glove, the regular hexagons of convex portions formed in a honeycomb shape on the outer surface of the glove face each other
  • Non-slip gloves are made with different angles between the straight line connecting the two apexes (honeycomb pattern direction 11) and the straight line connecting the skirt center of the glove body and the center of the middle finger (middle finger direction 10). The flexibility of the gloves was confirmed.
  • non-slip gloves are prepared in which the angle (honeycomb pattern angle) ⁇ between the honeycomb pattern direction 11 and the middle finger direction 10 is 0 °, 30 ° and 45 °, A sensory evaluation was performed on the flexibility of the fingers of each glove. Note that the inclination toward the thumb side (the right side in FIG. 5A and the side indicated by the arrow A) with respect to the direction toward the tip of the middle finger in the middle finger direction 10 is positive. The evaluation method was the same as in the flexibility test. The results are shown in Table 3.
  • the non-slip gloves according to the present invention which are excellent in moisture permeability and flexibility, are worn by workers in, for example, a factory, worn by workers when carrying work, worn by drivers when driving, etc. It can be used for various purposes.

Abstract

La présente invention concerne un gant antidérapant qui présente une excellente perméabilité à l'humidité et de la douceur. Ce gant antidérapant comporte un corps de gant réalisé en fibres (1) qui recouvre la main d'un porteur et une couche poreuse (2) qui est imprégnée dans et stratifiée sur la face extérieure du corps de gant (1) au moins dans la région de paume, la couche poreuse (2) étant faite d'une composition de résine à base de polyuréthanne, et ayant un motif de saillie/évidement formé par pressage sur la surface extérieure dans la région de paume. Il est préférable que le taux d'occupation de saillie du motif de saillie/évidement sur la surface extérieure de la couche poreuse (2) soit de 30 à 80%. En outre, il est préférable que le rapport de l'épaisseur moyenne des parties en retrait (4,14) à celle des parties en saillie (3,13) soit de 30 à 75%. Il est également préférable que le taux moyen de transmission d'humidité de la couche poreuse (2) dans la région de paume soit de 6000g/m2·24h ou plus.
