Definitions
- the present invention relates to a nonwoven whose curly or wavy structure gives it excellent absorption properties, making it particularly suitable for use as a medical or surgical compress.
- each compress is, in general, wrapped individually and sterilized.
- non-woven compresses are appreciably superior to those produced in gauze, with regard in particular to non-adherence to wounds, they nevertheless remain far below what is desired as regards the absorption capacity.
- the present invention relates to a nonwoven overcoming the defects of traditional nonwovens and gauze.
- this nonwoven has a succession of ripples uniformly distributed and whose adjacent bellies
- QMPI_ are alternately arranged above and below the median plane of the nonwoven.
- the contiguous belly of two neighboring undulations, situated on the same side of the median plane of the nonwoven, are made up of small adjacent pads.
- the nonwoven is a complex formed of a synthetic grid on which is fixed, in particular by thermobonding, a web of cellulosic fibers.
- Figure 1 is a top view of the nonwoven
- Figure 2 is a sectional view of Figure 1 along a plane parallel to the machine direction of the nonwoven
- Figure 3 is a sectional view of Figure 1 along a plane perpendicular to the machine direction of the nonwoven
- Figure 4 is a perspective view of a nonwoven consisting of a synthetic grid and a web of cellulosic fibers.
- Figure 1 is a top view of a nonwoven (1) which has a machine direction (2), corresponding to the longitudinal direction of production of said nonwoven, and a cross direction (3) perpendicular to the machine direction (2 ).
- This nonwoven (1) has corrugations or crimps regularly spaced apart and arranged along lines (5) parallel to the machine direction (2).
- Figure 2 which is a sectional view of Figure 1 along AA, plane parallel to the machine direction (2), shows that the nonwoven has corrugations (4) whose bellies (6, 7 ⁇ are alternati ⁇ vement above and below its median plane (8).
- Figure 3 which is a sectional view of Figure 1 along BB, plane perpendicular to the machine direction (2), shows that the contiguous bellies (9, 10) of neighboring corrugations consist of small adjacent pads (11, 12) located on the same side of the median plane
- FIG. 4 shows a preferred form of the invention: the nonwoven consists of a synthetic grid (13) formed of filaments (15) of a first polymer coated in a sheath of a second polymer and connected by thin strips (16) of the second polymer, grid on one side of which is deposited a web of cellulosic fibers (14).
- the veil (14) is thermally bonded to the grid (13): thus the nonwoven does not contain any chemical binder and can therefore be used as a medical or surgical compress.
- the synthetic grid (13) is a bi-stretched grid comprising in the machine direction (2) parallel polyamide filaments (15) regularly spaced by a distance of between 0.1 and 3 mm. and connected together by narrow polypropylene strips (16) regularly spaced by a distance between 0.1 and 3mm and perpendicular to the fila ⁇ ments (15).
- the veil (14) of cellulosic fibers consists of a carding veil of cotton fibers.
- this nonwoven has the advantage of being lighter than traditional gauze.
- the grid (13) has a grammage between 5 and 15 g / m 2 preferably 7 g / m 2 and the web of cellulosic fibers (14) a grammage between 10 and 20 g / m 2 , preferably 16 g / m 2 .
- the thickness is defined as the thickness of 10 superimposed sheets measured under a pressure of 20g / cm 2 .
- the absorption speed is defined as the penetration time, in the nonwoven, of a drop of water of 1/20 cm 3 deposited on the surface of said nonwoven using a pipette .
