A method of manufacturing a short stretch combined compression and absorption dressing/bandage, which includes
- manufacturing at least two needle-punched fibre batts of any one of viscose and cotton and polyester by means of a needle loom, each batt having an operative inner and outer face;
- sandwiching at least one layer of short stretch polyester knit between the at least two fibre batts with the operative inner face of the first fibre batt in direct contact with a first surface of the short stretch polyester knit and the operative inner surface of the second fibre batt in direct contact with a second surface of the short stretch polyester knit;
- and bonding the layers together by means of a needle-punching process to form a layered short stretch laminated pad.

A method of treating a wound, comprising:
- bandaging a wound with a combined compression and absorption dressing/bandage, wherein the combined compression and absorption dressing/bandage includes an inner layer sandwiched between a first outer layer and a second outer layer;
- and
- wherein:
- the inner layer is a short stretch compression bandage comprising a knit scrim;
- the first outer layer comprises a first absorptive wound dressing that is in direct contact with a first surface of the inner layer, the first absorptive wound dressing comprising at least one first absorbent layer having a first operative inner surface and a first operative outer surface;
- the second outer layer comprises a second absorptive wound dressing that is direct contact with a second surface of the inner layer, the second absorptive wound dressing comprising at least one second absorbent layer having a second operative inner surface and a second operative outer surface;
- the first and second absorbent layers each comprise a non-woven fabric of any one or more of cotton, viscose and polyester fibres;
- the first operative inner surface is in direct contact with the first surface of the inner layer;
- the second operative inner surface is in direct contact with the second surface of the inner layer;
- and
- the first and second outer surfaces face away from the inner layer.
30-33. (canceled)
A method of treating a wound, comprising:
- bandaging a wound with a combined compression and absorption dressing/bandage, wherein:
- the combined compression and absorption dressing/bandage includes a layered short stretch laminate pad that includes include at least one layer of a short stretch polyester knit sandwiched between at least two needle-punched fibre batts;
- the short stretch polyester knit has a first surface and a second surface
- each of the needle-punched fibre batts have an operative inner and outer face and include any one of viscose, cotton, and polyester;
- the operative inner face of the first fibre batt is in direct contact with the first surface of the short stretch polyester knit and the operative inner surface of the second fibre batt is in direct contact with the second surface of the short stretch polyester knit;
- and
- said at least one layer of short stretch polyester nit and said at least two needle-punched fibre bats are bonded to one another via needle punching.
