Abstract

A method for producing a compression garment for a user from an elastic fabric comprises the step of providing a base garment, fitting the garment on a supporting mannequin that has a plurality of independent heating means to independently heat different portions of the garment, measuring the compression applied to the mannequin portions by the garment and heating selected portions of the garment until the compression of the garment on the mannequin has reached a desired value.

First claim

The invention claimed is:

1. A method for producing a compression garment for a user, the compression garment having a plurality of size circumferential lengths at different axial garment locations to apply compression to corresponding locations of the user when said compression garment is worn, the method comprising the steps of:
A. providing a plurality of desired compressions to be applied by the compression garment on the user at said plurality of different axial garment locations;
B. producing a base garment with a woven fabric comprising elastic fibers, said fabric having a stretch of at least 15% when measured according to ASTM D3107;
C. disposing said base garment on a supporting mannequin, the supporting mannequin including a plurality of heaters located at different axial heater locations of said supporting mannequin and independently operable;
D. determining actual compressions exerted by the base garment on the supporting mannequin at different axial mannequin locations of said supporting mannequin corresponding to said different axial garment locations;
E. determining target compressions to be exerted by said base garment at said different axial garment locations on the supporting mannequin at said different axial mannequin locations, so that the compression garment exerts the desired compression at the different axial garment locations when worn by said user;
F. operating at least some of said heaters to heat said base garment at said different axial garment locations, so that the actual compressions exerted by the woven fabric of the base garment comprising elastic fibers, are lowered to reach the target compressions; and
G. cooling the base garment;
wherein, in said step B the base garment is produced so that, at said step C, non-null compressions are applied by the base garment to said supporting mannequin at said axial mannequin locations.

2. The method according to claim 1 , wherein in said step D, said determining actual compressions comprises measuring the actual compressions via sensors located on a plurality of supporting mannequin portions at said different axial mannequin locations of said supporting mannequin.

3. The method according to claim 2 , wherein said sensors further measure the actual compressions during said step F.

4. The method according to claim 1 , wherein the at least some of the heaters in said step F reach a temperature in the range of 100° C. to 130° C.

5. The method according to claim 1 , wherein an active time of the at least some of the heaters is calculated as a function of the difference between the actual compression and the corresponding target compression measured at the associated axial mannequin location.

6. The method according to claim 1 , wherein said operating the at least some of the heaters comprises ending heating treatment of the heaters at substantially the same time.

7. The method according to claim 1 , wherein said cooling is performed by circulation of a coolant in the supporting mannequin or use of at least one peltier device.

8. The method according to claim 1 , wherein said cooling provides for a loss of temperature of the supporting mannequin of at least 100° C. degrees at at least one axial mannequin location, in less than 30 seconds.

9. The method according to claim 1 , wherein at least part of said cooling is performed with the base garment disposed on the supporting mannequin.

10. A system for performing at least said steps C to G of the method according to claim 2 , said system comprising:
the supporting mannequin with said plurality of supporting mannequin portions at said different axial mannequin locations;
the plurality of independently operable heaters, said supporting mannequin portions disposed separate from one another;
a cooling system configured to cool the base garment disposed on the supporting mannequin; and
the sensors configured to measure said actual compression at said different axial mannequin locations of said plurality of said supporting mannequin portions.

11. The system of claim 10 , further comprising a programmable logic control (plc) control unit configured to receive compression data from said sensors and to independently operate said heaters to heat said supporting mannequin portions for a required time as a function of said compression data.

12. A garment formed according to the method of claim 9 , wherein at said different axial garment locations, the fabric has different elastic properties, said elastic properties comprising at least one of stretch, growth recovery according to ASTM D3107 at least in the weft direction, tensile strength at least in the weft direction, and crystallinity.

13. A method for modifying elastic properties of a garment comprising the steps of:
providing a base garment with a fabric comprising elastic fibers, and having stretch of at least 15%;
disposing said base garment on a supporting mannequin, the supporting mannequin having a plurality of supporting mannequin portions at a plurality of axial mannequin locations, the supporting mannequin including a plurality of heaters operable independently to independently heat said supporting mannequin portions at said axial mannequin locations wherein the base garment applies non-null compressions to said supporting mannequin portions as produced;
determining target compressions to be exerted by said base garment at different axial garment locations associated with said plurality of axial mannequin locations, so that a compression garment exerts a desired elastic compression at the different axial garment locations when worn by said user;
operating the heaters to heat the base garment at at least some of said supporting mannequin portions to lower the non-null compressions exerted by the base garment; and
cooling the base garment once said target compression values are reached.

14. The method according to claim 13 , further comprising sensors of the supporting mannequin measuring said non-null compressions.

15. The method according to claim 13 , wherein the use different active times to treat the garment differently at the different axial supporting mannequin locations.

16. A garment obtainable from a woven fabric according to the method of claim 13 , wherein samples of the garment fabric taken at different axial size locations of the garment have different elastic properties, said elastic properties including stretch and growth recovery according to ASTM D3107 at least in the weft direction.

17. The garment according to claim 12 , wherein two fabric samples taken from two parts X and Y at different said axial size locations of said garment have a stretch value according to ASTM D3107 of SX and SY, respectively, and wherein the ratio of said stretch values (SX−SY/SX)*100 is in the range of 4% to 50%.

18. The garment according to claim 12 , wherein two fabric samples taken from two parts X and Y at different said axial size locations of the said garment have different values for at least one of tensile strength and crystallinity.

19. The method according to claim 1 , further comprising entering body measurements into a programmable logic control (plc) control unit and wherein said body measurements are processed by an algorithm that creates said target compressions.

20. The method according to claim 13 , further comprising entering body measurements into a programmable logic control (plc) control unit and wherein said body measurements are processed by an algorithm that creates said target compressions.
