[0051] FIG. 6E,

[0052] FIG. 6F and

[0053] FIG. 6G illustrate the steps of the method for packaging the piece of protective clothing in the packaging pouch of FIG. 1.

[0054] In the rest of the description, the expressions outer and inner refer to the use of the piece of clothing by a user, an inner surface being closer to the user than an outer surface under conditions of normal use of the piece of clothing.

[0055] A piece of protective clothing 1 for a cleanroom or asepticised environment is illustrated in FIG. 1.

[0056] The piece of protective clothing 1 is, here, a suit comprising a first and a second leg sections 2, 3.

[0057] Alternatively, the piece of protective clothing could be a pair of trousers 20 as illustrated in FIG. 5 in which the same elements carry the same references. The piece of protective clothing could also be a top, a balaclava, or any other type of piece of protective clothing.

[0058] The leg sections 2, 3 can, in a manner that is in no way limiting, be provided with closing means (not shown).

[0059] The piece of protective clothing 1 also comprises a first sleeve 4, a second sleeve 5 and a body part 6. The first sleeve 4, the second sleeve 5, the two leg sections 2, 3 are each connected to the body part 6 to form a suit.

[0060] The body part 6 comprises a head passage section 7 and an opening 8 closed by closing means, for example a zip fastener.

[0061] The suit 1 comprises an outer face 1a provided to be in contact with the outside environment and an inner face 1b arranged to be in contact with the user wearing said suit.

[0062] The suit 1 comprises a packaging pouch 10 comprising a single wall 11 connected by its contours to the inner face 1b of the suit by irreversible fastening means 12, such as welding or sewing.

[0063] The wall 11 of the packaging pouch 10 comprises an outer face 11a visible in FIGS. 2 and 3 provided to be in contact with the outside environment once the piece of clothing has been packaged in the pouch 10.

[0064] The wall 11 of the packaging pouch 10 comprises an inner face 11b provided to be in contact with the user wearing said suit.

[0065] In the configuration of use of the suit by the user, the outer face 11b of the pouch 10 faces the inner face 1b of the body part 6 of the suit 1.

[0066] Thus, in the folded and packaged position, the inner face 1b of the suit 1 is connected to the inner face of the wall in such a way that only the outer face of the pouch is in contact with the outside environment, as illustrated in FIGS. 2 and 3.

[0067] The wall 11 of the packaging pouch 10 has, here, a parallelepipedic shape comprising four corners 13a, 13b, 13c, 13d.

[0068] The wall 11 of the packaging pouch 10 further comprises an opening 14 extending between two diagonally opposite corners 13c, 13b, as visible in FIG. 2.

[0069] The opening 14 has, here, a rounded shape in order to facilitate the extraction of the piece of clothing from said pouch, as well as its repackaging.

[0070] The opening forms, here, a half-circle.

[0071] The opening 14 comprises a zip fastener 15 intended to close said opening 14.

[0072] In a manner that is in no way limiting, the wall 11 of the packaging pouch 10 also comprises a flap 16 intended to cover the zip fastener 15 in the packaged position of the piece of clothing 1 in the packaging pouch 10.

[0073] Alternatively, the packaging pouch could not have a flap.

[0074] The flap 16 is connected to the wall 11 partly along two sides in order to be able to switch from a free position of the zip fastener 15, visible in FIG. 2, towards a covered position of said zip fastener 15, visible in FIG. 3.

[0075] The flap 16 is made of textile material.

[0076] The flap 16 allows to reduce the entry of the particles by the zip fastener 15 which is thus covered by a protection.

[0077] The flap 16 is provided, at each opposite corner, with an opening 16a, 16b in order to avoid the accumulation of particles at the zip fastener 15.

[0078] The repackaging of the piece of clothing 1 inside the pouch 10 is carried out as follows, in reference to FIGS. 6A to 6G.

[0079] During the first step of the method for repackaging the piece of clothing, the user folds the suit 1 so as to leave visible the inner face 11b of the pouch 10, as illustrated in FIG. 6A.

[0080] Once the suit has been folded, the user grips the suit 1, in particular its inner surface 1b, by the inside of the pouch 10, as visible in FIG. 6B and pulls on the suit 1 through the opening 14 until the suit 1 ends up inside the pouch 1 as visible in FIGS. 6C and 6D.

[0081] Once the suit 1 has been placed inside the pouch 10, as visible in FIG. 6E, the user closes the opening 14 by actuating the zip fastener 15, as visible in FIG. 6F.

[0082] The user then folds over the flap 16 and in particular until it covers the zip fastener 15, as visible in FIG. 6G.

[0083] The suit 1 thus packaged in the pouch 10 can be sterilised, for example, in an autoclave.

[0084] When the user puts on the suit 1 again, they open the means 15 for closing the opening 14 of the pouch 1, remove the suit 1 from the pouch by pulling on it by its inner face 1b.

[0085] Via the invention, a piece of protective clothing for a cleanroom that is easy to package and to unfold is obtained, while reducing the environmental and ecological impact, without having a negative effect on the sterility of the environment.
