DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to a method for producing elastic protective material, which is formed of at least two part materials being in connection with each other. The first part material is intended particularly to give mechanical protection, such as to prevent a concrete object from breaking through the same. The second part material is intended particularly to give non-mechanical protection, such as to prevent gas, liquid and/or like from going through the same. To achieve an elastic protective material the first part material is produced at least partly by knitting preferably from polymer fiber material or the like. The second part material, such as one or several polymer material layers or the like is arranged in connection with the knitted layer, that has been produced, at least partly built-in during production.
The method according to the invention is applicable for manufacturing of protective material for most heterogeneous purposes. Thus the protective material according to the invention may be advantageously used as manufacturing material particularly for example for protective clothings, such as for safety gloves or the like intended particularly for medical purposes.
BACKGROUND OF THE INVENTION
In the purpose above, safety gloves made of most heterogeneous materials are presently very generally used, that are usually made by a soaking method or dipping. Particularly because of todays dangerous deseases (e.g. AIDS), that are easily infectious, it is first and foremost important to achieve simultaneously when using a safety glove both adequate hygienic protection to prevent e.g. virus, bacteria infections or the like and mechanical protection e.g. against unintended cuts and injections. Safety gloves that are being used in this purpose today do not work well enough. That is why it is very common to use two safety gloves one on another, which naturally makes the use of the safety gloves slower and more difficult. The use of two gloves one on another does not, however, improve mechanical strenght of the basic material of the safety glove decisively particularly considering durability against injections or cuts. This is why in the type of safety gloves in question there has been applied e.g. different kinds of chemical indication arrangements, so that a damage of the safety glove could be revealed e.g. by a change in color at a wounded point of the safety glove. However, during an operational situation, in practice, the situation must be considered as a whole so, that when the condition of the patient is critical, the person making an operation is not always able to change the safety glove even if it has broken. This is why a person making e.g. surgical measures continuously may very often be involved to risk his own health for the sake of the patients' interests.
Finnish Patent Application No. 931396, "Menetelma ja lajitelma kehon tai sen osan suojaamiseksi ja/tai sen toiminnan tehostamiseksi", presents a solution, developed in certain ways with respect to present safety gloves, particularly when compared to those mentioned before. In the invention in question, it is first of all essential, that the clothing to be dressed, such as a protective glove or like, is equipped with ducts transmitting energy, such as with light fibers or the like e.g. to lead light to the operating point along fingers.
The safety glove that is included in the solution in question, comprises as an advantageous embodiment an elastic structure part, that is knitted or woven from high-tenacity fibers made of polymer, whereby as the fiber types different kinds of coal and polyethene fibers, aramid fibers, tissues and/or the like are being used, in which case the protective glove stands further e.g. both autoclaving and ethylene claving, that is performed e.g. in connection of a sterilization of the safety glove enabling re-use of the same.
When making the type of clothing or protective glove in question, multi-layered e.g. the inner layer by knitting, as described above from strong artifical fibers and
