Garment multilayered-lining sewing process
View Patent ↗This disclosure relates to a sewing process of a breathable, reusable, and leak-proof garment multilayered-lining having absorbent, antimicrobial, waterproofing, and steam dispersion functions. Such lining aims at preventing body fluids such as sweat, blood, vaginal fluids, menstrual fluid, urine, breast milk, or post-surgical fluids from leaking. Such a lining provides the absorbent, antimicrobial, waterproofing, and steam dispersion functions. The lining may be sewed or adhered to the garment piece including: men's and women's underwear, shorts, short pants, skirts, pants, bras, shirts, T-shirts, jumpsuits, body shapers, dresses, men's and women's nightwear, etc. The sewing process creates channels for the liquid and creates a non-linear U-shaped structure on the lining to prevent leakage from the sides. The disclosed lining also has a reduced number of layers on its sides due to one of its layers being smaller in width than the other layers, making the coating thinner for the wearer.
1. A method of generating a multilayered-lining garment, comprising:
providing a first layer, a second layer, a third layer, a fourth layer, and a fifth layer;
cutting the first layer, the second layer, and the third layer to have a size equal to one another;
sewing the third layer and the fourth layer together at a position that is approximately 1 to 3 cm from side edges of the third layer;
sewing the first layer, the second layer and the third layer together at first and third end edges thereof;
sewing the fifth layer together with the first layer, the second layer, and the third layer at side edges thereof that define openings of lining-legs by using fabric tape or sewing; and
joining the first layer, the second layer, the third layer and the fifth layer by sewing with elastics, laces, or other finishings.
2. The method of claim 1 , wherein the sewing is performed using needles from size 60 to size 90.
3. The method of claim 1 , wherein the sewing is performed using polyester thread 120 to 160 or polyester thread with antimicrobial and anti-leak treatment.
4. The method of claim 1 , wherein the fifth layer includes a finishing material comprising one or more of cotton, modal, bamboo, viscose, polyester, microfiber, nylon, including combinations with elastane, lycra, and spandex.
5. The method of claim 1 , wherein the first layer includes a natural or synthetic material including one or more of cotton, polyester, bamboo, viscose, tinsel, modal, and nylon.
6. The method of claim 1 , wherein the first layer includes a natural or synthetic material that includes a branched, woven fabric, fleece, terrycloth, or microfiber structure.
7. The method of claim 6 , wherein the third layer is knitted or woven, and optionally includes 51% of modal, viscose, bamboo, carbon, or cotton having 90 to 300 gsm2.
8. The method of claim 6 , wherein the fourth layer includes at least 90% either of polyester or microfiber having 100 to 300 gsm2.
9. The method of claim 1 , wherein the first layer includes a natural or synthetic material that is between 60 and 350 g/m2 by weight.
10. The method of claim 1 , wherein the first layer includes breathable thermoplastic polyurethane having thickness in a range from approximately 0.015 to approximately 0.020 mm that is not treated with a chemical product.
11. The method of claim 1 , wherein the multilayered-lining garment further includes a sixth layer, and the sixth layer or the third layer is chemically treated with an antimicrobial product.
12. The method of claim 1 , further comprising:
a sixth layer;
treating one or more of the third layer, the fourth layer and the sixth layer with an antimicrobial product; and
joining the third layer, the fourth layer, and the sixth layer by a U-shaped seam.
13. The method of claim 1 , further comprising:
using the multilayered-lining garment to generate a garment having a form of a bra.
14. The method of claim 1 , further comprising:
sewing the fifth layer on an inner garment layer.
15. The method of claim 1 , further comprising:
sewing the first layer using an additional finishing stitch on a gusset.
16. The method of claim 11 , wherein the antimicrobial product contains zinc.
17. The method of claim 1 , wherein the fourth layer is approximately 0.1 to 0.3 cm smaller in length than a length of the first layer, the second layer, and the third layer.
18. The method of claim 1 wherein the first layer, the second layer and the fourth layer are disposed between the third layer and the fifth layer;
the first layer is an antimicrobial layer, the second layer is a waterproofing layer, and the fourth layer is an absorbent layer;
the first layer is disposed between the second layer and the fifth layer;
the second layer is disposed between the first layer and the fourth layer;
the fourth layer is disposed between the second layer and the third layer.
19. The method of claim 1 , wherein sewing the third layer and the fourth layer together comprises using chain stitch (ISO 101 ), zig-zag lockstitch (ISO304), or three-thread overedge stitch (ISO 401 ); and
sewing the fifth layer together with the first layer, the second layer, and the third layer at side edges thereof that define openings of lining-legs by using fabric tape or sewing comprises using blind stitch, three-thread overedge stitch (ISO 504 ), zig-zag lockstitch (ISO 304 ) or bottom cover stitch (ISO 406 ).
