Even if no agent is used, both (both sides) are bonded to each other at the portion where the front and back surfaces of the non-woven fabric overlap based on the fine crimp structure of the single fibers constituting the non-woven fabric. It has a function. In particular, when the stretch-recovered nonwoven fabric is pressed in such a way that the front and back surfaces are overlapped while applying a little tension in the length direction, the crimped structures of the constituent fibers on both sides become more entangled and strongly bonded. You can gain power.
  • This joining can be easily separated without any particular destruction of the nonwoven fabric when a force is applied so that a person peels off. While the stretch-recovered nonwoven fabric maintains its form, Separation (detachment) can be freely repeated many times.

  • the behavior / mechanism described above is the joining by entanglement / meshing that occurs when two coil springs having substantially the same helical diameter and pitch are placed adjacently in parallel and overlapped while extending the coil. It is understood as the same kind.
  • the bonding of the back surface of the stretch-recovered nonwoven fabric with the back surface of the self-recovery nonwoven fabric is performed with a certain amount of tensile force applied (ie, the above “coil”). Higher and more effective binding force when rolled and joined, while stretching the “reduced loop structure”.
  • the force to be unwound acts as a force parallel to the surface direction of the stretch-recovered nonwoven fabric, and the stretch-recovered nonwoven fabric attempts to greatly counter the force. It is.

If both ranges are satisfied, sucking blood will increase the thickness to a certain extent and swell to increase the volume, thereby realizing an appropriate pressing force.

  • the pressure-sensitive self-surface back-bonded stretch recovery nonwoven fabric exceeds at least one circumference of a part of the human body, that is, the nonwoven fabric is at both ends in the length direction. It is important to have a length sufficient to allow the front and back surfaces of the self to be wound so as to overlap. This is because the stretch-recovered nonwoven fabric does not have a special bonding force to the skin, and the bonding force is exhibited by overlapping the front and back surfaces of both ends of the nonwoven fabric itself. According to the knowledge of the present inventors, it is sufficient that the length is about 10 to 60% or more in addition to the above-mentioned one round. However, since there are personal differences and differences in the parts to be used, as long as the product has a length of about 30 cm to 100 cm, it is sufficiently good to cope with various cases.

It is important that the recovery rate after 50% elongation is 85% or more and 95% or less.
  • the elongation recovery performance of the nonwoven fabric is such that the elongation at break is such that it is broken and not impaired in normal use during hemostasis.
  • the longitudinal elongation at break is 500%. If it is too high, it is difficult to obtain a stable high front / back bonding force (and hence a high pressing force to the blood-stopped part), which is not preferable. If the longitudinal elongation at break is less than 95%, there will often be a part where the nonwoven fabric itself will be deformed to a state where the stretch recovery performance of the nonwoven fabric itself will not return to its original state even with a slight elongation. The bonding force between the front and back surfaces and the binding force are likely to be reduced, and the effects of the present invention are difficult to obtain.
  • the recovery rate after 80% elongation in the length direction is less than 60%, the elongation recovery stress of the stretch recovery belt is reduced. For this reason, the hemostatic pressure made by the tensile stress of the nonwoven fabric decreases, and the original purpose (hemostasis) cannot be achieved. This is because, when the degree of elongation of the nonwoven fabric becomes too large, the entangled structure between the fibers inside the nonwoven fabric begins to break, and the transmission of stress between individual fibers is impaired. In this state, even if the nonwoven fabric belt can be stretched, the stretch recovery rate and recovery force of the belt obtained at that time are small, so the hemostatic pressure is small, which is not preferable. When the recovery rate after 80% elongation in the length direction is greater than 85%, the binding force obtained by stretching the nonwoven fabric belt becomes too large, and the hemostatic pressure becomes too large, which is not preferable.
  • the recovery rate after elongation by 50% in the length direction is less than 85% because the obtained binding force tends to be small.
  • the recovery rate after extending 50% in the length direction is larger than 95%, the binding force obtained by extending the nonwoven fabric belt becomes large, and the hemostatic pressure becomes larger than a desired level, which is not preferable.

  • the hemostatic belt of the present invention having the above-described characteristics is preferably used at a longitudinal elongation rate in the range of about 20% to 100% in general due to the correlation between the elongation and the binding force of the stretch-recovered nonwoven fabric. It is appropriate and desirable for expressing a binding force to obtain an appropriate pressing effect and a high hemostatic effect.

  • This non-woven fabric was slit in the length direction of the non-woven fabric with a width of 5 cm, and was rolled up into a roll shape to obtain a stretch recovery self-adhesive belt.
  • this nonwoven fabric is slit with a width of 3 cm ⁇ length of 35 cm, and a cellulose sponge pad having a length of 25.1 mm, a width of 25.0 mm, a thickness of 1.03 mm when dried before use and a water absorption swelling ratio of 790% is used as a hemostatic pad, and is adhered.
  • a hemostatic belt was prepared by attaching with an agent and evaluated.
  • Table 1 shows the results of evaluating each of Examples 1 to 8 and Comparative Examples 1 and 2. According to the present invention, the self-adhesion was strong and the intended purpose was sufficiently achieved.
  • any of Examples 1 to 8 after starting to be used as a hemostatic belt, it is possible to disengage the belt once, then wind it again and re-engage it. It is easy to use because it can be pressed again.
  • the pressure-sensitive self-surface back adhesive stretch recovery nonwoven fabric obtained in Example 1 and Example 2 was examined for air permeability and moisture permeability.
  • the air permeability of the nonwoven fabric of Example 1 was 136 cm 3 / cm 2 / sec

  • Comparative Example 3 A commercially available spunbond nonwoven fabric (100 g / m 2 basis weight) made of 100% polyethylene terephthalate fiber was prepared. The nonwoven fabric was lightly pulled by hand to such an extent that it did not break, and then the stress was released.
  • the self-adhesiveness between the non-woven fabrics was not observed even when pressure was applied with the non-woven fabrics piled up.
  • the elongation at break was 20%. Therefore, it was not possible to extend 50% in the length direction, and the hemostatic belt of the present invention could not be constructed at all.
  • Comparative Example 4 The hemostatic pad was fastened by using a longitudinal stretch bandage (plain woven fabric) to which self-adhesiveness was imparted by applying an adhesive to the hemostatic belt.
  • This longitudinal stretch bandage (plain woven fabric) is originally a taping material for sports, and the pressure and pressure of the hemostatic pad during hemostasis tend to be too strong, and the appropriate pressure of the hemostatic pad is naturally appropriate. ⁇ It was difficult to use with the pressure.
  • Comparative Example 5 A hemostatic pad was fastened using a non-self-adhesive longitudinal stretch bandage (plain woven fabric) as a hemostatic belt.
  • This longitudinal stretch bandage (plain woven fabric) is originally a taping material for joints such as elbows and knees, and the tape is not self-adhesive. It was not possible to use it with pressure.
