Definitions
- the present invention relates to a method for sealing assembly seams between those to be connected
- Cloth edges in patient drapes and surgical clothing in particular those made from a trilaminate with a microporous membrane embedded between a textile upper and a lower layer, by means of a seam sealing tape.
- This material is light and has a high flexibility and good drapability.
- the cover layers are made of special crepe material with a stretch effect, which effect is kept smaller than the stretchability of the membrane. This prevents the membrane from overstretching. This stretch gives the material a buffer effect, whereby the physical forces are cushioned, especially in the preparation.
- the material is liquid-tight even under high pressure loads and forms a safe barrier against the penetration of bacteria and viruses.
- the membrane does not represent an obstacle for water vapor molecules
- this trilaminate offers increased product safety, since possible perforations or mechanical damage preparation become visible on the light table and can therefore also be repaired with patches.
- Another textile barrier material for patient cover and surgical clothing is a microfiber fabric which, due to the very high fabric density, represents an effective dry germ barrier, and the carbon fibers used ensure permanent antistatic properties.
- a slightly heavier tri-laminate is preferably used, while trilaminate shields the immediate area surrounding the surgical procedure.
- the material made of microfibers is used in the peripheral areas wherever there is no more fluid.
- the jacket front and sleeves are made of trilaminate.
- the backing material consists of the breathable, antistatic microfiber fabric.
- the materials described above are suitable for a variety of reprocessing cycles (washing and sterilizing), e.g. at least 50 cycles without losing the basic properties.
- the object of the present invention was to create a method of the type defined at the outset which allows the sealing of ready-made seams which are intended to ensure the same properties as the wipes themselves. This object was achieved according to the invention by the features according to the characterizing part of claim 1.
- the invention also relates to patient drapes and surgical clothing produced by the method of claim 1.
- the seam sealed according to the invention like the cloth itself, has no germ penetration in the moist state, and likewise no penetration for viruses and bacteria. In the case of invisible penetrations, there is no bacterial / viral penetration.
- the sealing tape used will preferably be 25 or 28 mm wide and consists of a 100% charmeuse special fabric.
- An adhesive based on polyurethane (preferably transparent) is used for gluing or welding onto the seam and is used, for example, in an amount of 350-380 g / m2.
- Processing on a hot air welding machine is preferably carried out at 520 ° C - 530 ° C under a hot air pressure of 0.55 - 0.6 bar between welding rollers (pressing pressure e.g. 5 - 6 bar).
