Description

BRIEF DESCRIPTION OF THE FIGURES

[0014] The following is a description of the present disclosure according to the various embodiments depicted in the figures.

[0015] FIG. 1 is a schematic view showing the multilayer lining for clothing composed by layers A, B, C and D.

[0016] FIG. 2 is a schematic view showing the multilayer lining for clothing composed by layers A, B, C, D1 and D2.

DETAILED DESCRIPTION OF THE DISCLOSURE

[0017] The present disclosure provides a multilayer lining for clothing that may be used in garments, for example in men and women's underwear.

[0018] The multilayer lining for clothing has at least 4 (four) layers, wherein the first layer A is made of outer finish material, selected from the group including: cotton, modal, bamboo, viscose, polyester, microfiber, nylon, including combinations with elastane, lycra and spandex.

[0019] A second layer B of a natural or synthetic material selected from a group including: cotton, polyester, bamboo, viscose, tinsel, modal and nylon with a weight between approximately 60 and 350 g/m2, and it may have a mesh structure with twisted fabric, fleece, plush or microfiber. This layer is chemically treated with an antimicrobial product, especially with products containing silver ions, such as Silpure (product by Thomson Research associates).

[0020] The third layer of the multilayer lining, layer C, is composed of breathable thermoplastic polyurethane of approximately 0.015-0.020 mm, which is applied without using any harmful chemicals, such as those present in linings already known in the art.

[0021] A fourth inner layer, layer D, is a contact layer made of any fabric with appropriate features for absorption, hygiene, draining, etc.

[0022] Layer C, the third layer, is fixed to the second layer, layer B, by a lamination process, with heat application. The rest of the layers are bonded through a specific sewing process.

[0023] The combination of waterproof layer C and antimicrobial layer B increases antimicrobial effectiveness due to the fact that layer C is located at the bottom of the multilayer lining, so that most of the absorbed liquid is not in contact with the antimicrobial fabric. In addition, the organization of layers B and C improves the flexibility of the garment when using the multilayer lining. Also, because of the layer layout, the lining of the present disclosure is not too thick, so its use becomes more comfortable for the user.

[0024] In another modality of the present disclosure, layer D is replaced by layers D1 and D2. Layer D2 is an optional layer with an absorbing function, while layer D1 is the inner layer.

[0025] Layer D1 is the inner layer of the lining, which may be made of approximately 51% of the following materials: modal, viscose, bamboo, carbon or cotton with approximately 90-300 gsm. Additionally, layer D1 may be knitted or weaved with a special pattern to be created as follows: (1) bigger openings or conduits for the liquid, wherein the said conduits facilitate the mechanical passage, through capillary absorption, to the next layer. This liquid includes, but is not limited to, liquids with high viscosity and/or less polarized than water, with (2) 3D texture providing a larger contact surface towards the bodyallowing a faster drying and a drier touch if compared with Jersey fabric of simple or double mesh of comparable weight and denier.

[0026] Layer D2 of the present disclosure is an absorbent layer made of at least approximately 90% polyester or microfiber with coolplus fiber, integrated with rapid absorption and drying technology as well as cooling properties with approximately 100-300 gsm. Coolplus fibers are different from technologies commonly used in clothing manufacture with rapid absorption and drying, since such technologies use chemicals that may fade after washing due to the fact that they were developed with rapid absorption and drying functions. Additionally, because coolplus fibers are directly added to the fabric, they are the most resistant ones, and they do not get damaged or loose over time. Such features help to regulate temperature, preventing it from increasing in the lining.

[0027] Depending on the purpose of the multilayer lining for clothing, this layer may be optional or present in larger quantities.

[0028] The multilayer lining for clothing may resist up to 60 washes in a washing machine, provided that due care is taken, may comply with IS20743 standard, and may stand a waterproofing test for up to 12 hours while applying 500 mL of fluid. It may also be pervious to air.

[0029] The skilled in the art will value the knowledge provided herein and will be able to reproduce the disclosed lining in the presented embodiments, as well as in other variations, included in the scope of the annexed claims.
