Abstract

The invention relates to a protective clothing unit, in particular a protective clothing unit having fragment protection, preferably having a protective function against fragments created and/or released by detonation and/or explosion, comprising outerwear and/or underwear and possibly comprising separate head and/or face protection, neck protection, shoulder protection, arm protection, hand protection, trunk protection, torso protection, genital and/or anal protection, and/or leg protection, wherein the protective clothing unit has fragment protection elements, preferably textile fragment protection elements, which are specific and different from each other and which are associated with different body regions when worn and/or cover different body regions when worn, preferably having a protective function against fragments created and/or released by detonation and/or explosion.

First claim

What is claimed is:

1. A fragment-protective apparel unit having a protective function against fragments caused or released by detonation or explosion, the fragment-protective apparel unit comprising at least one of outerwear and underwear and, optionally, also one of separate head protection, face protection, neck protection, shoulder protection, arm protection, hand protection, trunk protection, torso protection, genital protection, anal protection and leg protection;
wherein the protective apparel unit includes different textile fragment protection elements, which textile fragment protection elements have a protective function against fragments caused or released by detonation or explosion and, in the state of use, are assigned to or cover different body regions, and
wherein the fragment protection elements each, independently from each other, include or consist of at least one ultra-high molecular weight polyethylene (UHMW-PE) and are each, independently from each other, configured as a knitted textile fabric, wherein the knitted textile fabric has a basis weight in the range from 125 g/m 2 to 500 g/m 2 ,
wherein the knitted textile fabric includes a multiplicity of needle loops and a multiplicity of at least one other structural element different from needle loops,
wherein the at least one other structural element is a tuck loop or a float;
wherein the ultra-high molecular weight polyethylene (UHMW-PE) is present as a filament yarn to form or as constituent part of the knitted textile fabric of the fragment protection elements;
wherein the filament yarn has a linear density in the range of from 50 to 500 dtex, a tenacity in the range of from 2 N/tex to 8 N/tex, and a breaking extension in the range of from 0.5% to 10%;
wherein the filament yarn consists of at least four and up to 800 individual filaments, and
wherein the filament yarn has a diameter in the range from 4 μm to 250 μm, and
wherein the fragment protection elements each, independently from each other, have a fragment or ballistic protection value V50, determined as per the method of STANAG 2920, of at least 180 m/s.

2. The protective apparel unit as claimed in claim 1 ,
wherein the fragment protection elements each, independently from each other, include at least one knitted textile fabric in the form of a formed-loop knit, a warp-knitted fabric or a weft-knitted fabric;
wherein the fragment protection elements each, independently from each other, have a fragment or ballistic protection value V50, determined as per the method of STANAG 2920, of at least 200 m/S.

3. The protective apparel unit as claimed in claim 1 ,
wherein the fragment protection elements each, independently form each other, have a fragment or ballistic protection value V50, determined as per the method of STANAG 2920, in the range of from 200 m/s to 800 m/s.

4. The protective apparel unit as claimed in claim 1 ,
wherein the filament yarn has a density in the range of from 800 kg/m 3 to 1200 kg/m3.

5. The protective apparel unit as claimed in claim 1 ,
wherein the knitted textile fabric is further provided with at least one further material other than ultra high molecular weight polyethylene (UHMW-PE).

6. The protective apparel unit as claimed in claim 5 ,
wherein the further material other than ultra high molecular weight polyethylene (UHMW-PE) is in the form of a yarn, filament yarn, thread or strand; and
wherein the further material other than ultra high molecular weight polyethylene (UHMW-PE) provides at least one of antimicrobial, biostatic, elastic, hydrophilic, fire-resistant and flame-resistant properties.

7. The protective apparel unit as claimed in claim 1 ,
wherein the knitted textile fabric is in the form of a two-dimensional textile sheet material and
wherein the knitted textile fabric is air-permeable and has an air transmission rate, determined according to DIN ISO 9237, of at least 10001/m2·min; and
wherein the knitted textile fabric is water-vapor permeable and has a water vapor transmission rate at 20° C. of at least 201/m2 per 24 h; and
wherein the knitted textile fabric has a thickness in the range of from 0.05 mm to 50 mm.

8. The protective apparel unit as claimed in claim 1 ,
wherein the knitted textile fabric has rib-shaped elevations on the area facing the wearer in the state of use.

9. The protective apparel unit as claimed in claim 1 ,
wherein the protective apparel unit further includes at least one further textile sheet material,
wherein the further textile sheet material combines with the fragment protection elements to form a single plied or single-layered area of the protective apparel unit, and
wherein the further textile sheet material is bonded or attached to the fragment protection elements.

10. The protective apparel unit as claimed in claim 1 ,
wherein the protective apparel unit comprises an undershirt or an overshirt,
wherein the undershirt or overshirt, in the state of use, extends at least partly over the region of the upper extremities or of the torso or of the neck/shoulder region or at least partly covers the upper extremities or the torso or the neck/shoulder region, or
wherein the undershirt or overshirt, in the state of use, extends at least partly over or at least partly covers the region of the lower abdomen or of the urinary bladder tract, of the lower back or of the renal pelvis, of the torso, of the lateral or posterior torso, of the upper or lower arm, of the cheliton or of the cubitus, of the shoulder or of the neck.

11. The protective apparel unit as claimed in claim 1 ,
wherein the protective apparel unit comprises at least one covering material.

12. The protective apparel unit as claimed in claim 11 ,
wherein the covering material is in the form of a textile sheet material; and
wherein the covering material is at least one of fire-resistant and flame-resistant.

13. The protective apparel unit as claimed in claim 1 ,
wherein the protective apparel unit is additionally equipped or provided with at least one adsorbent for chemical poisons or warfare agents.

14. A fragment-protective apparel unit having a protective function against fragments caused or released by detonation or explosion, the fragment-protective apparel unit comprising at least one of outerwear and underwear and, optionally, also one of separate head protection, face protection, neck protection, shoulder protection, arm protection, hand protection, trunk protection, torso protection, genital protection, anal protection and leg protection;
wherein the protective apparel unit includes different textile fragment protection elements, which textile fragment protection elements have a protective function against fragments caused or released by detonation or explosion and, in the state of use, are assigned to or cover different body regions, and
wherein the fragment protection elements each, independently from each other, include or consist of at least one ultra-high molecular weight polyethylene (UHMW-PE) and are each, independently from each other, configured as a knitted textile fabric, wherein the knitted textile fabric has a basis weight in the range from 125 g/m 2 to 500 g/m 2 ,
wherein the knitted textile fabric includes a multiplicity of needle loops and a multiplicity of at least one other structural element different from needle loops,
wherein the at least one other structural element is a tuck loop or a float;
wherein the ultra high molecular weight polyethylene (UHMW-PE) is present as a filament yarn to form or as constituent part of the knitted textile fabric of the fragment protection elements;
