General information

The recycled woollen fibres blankets are made from second hand clothes various fibres. New fibres may be included as well. Recycled wool is cheaper than virgin wool, and is appropriate to all types of climates, under the condition that our minimum specifications are met, and good manufacturing practices are respected.

The insulation capacity of a blanket depends of the thermal resistance (Rct) and of the air permeability of the material. The thermal resistance does not depend only on the weight or the raw material, but also on the fibre quality, the type of weaving or knitting, and fibre raising.

Low Thermal type, with Rct=0.15m².K/W is appropriate for indoor use, on a bed, in a house with heating facilities.

Medium thermal type, with Rct=0.25 m².K/W, is the minimum for hot or temperate climates outdoor use (even in hot countries, nights can be cold).

High thermal type, with Rct=0.4 m².K/W, is appropriate for cold climates.

Scientific studies defined that indoors at 20°C a person at rest requires a total insulation of Rct=0.15 m².K/W. Outdoors with no wind the value at 10°C is Rct=0.4 m².K/W, at 0°C it is Rct=0.6 m².K/W, at -10°C it is Rct=0.8 m².K/W and at -20°C it is Rct=0.95 m².K/W. Bearing in mind that a part of the insulation comes from the clothing, the rest will come from the blanket.

The Rct value can only be tested in a textile laboratory.

Low air permeability ensures protection from draughts, while inherent breathability allows evacuation of body perspiration.

In previous publications, the Thermal Resistance was given as ToG (Thermal Resistance of Garment). It is important to note that ToG=1 is identical with Rct=0.1 m².K/W. The major difference is the laboratory equipment to control these values. The Rct test is more accurate than the ToG test.

Other colours than the standard are available at higher costs and longer lead-time.

Blankets are subject to International Purchase Frame Agreements with validated manufacturers. Please refer to your HQ before purchasing.

Specifications

Test conditions	Specification under the normal textile test conditioning ISO139, 65% moisture and 20°C for 24h.
Samples for testing purpose	Samples of blankets must be from compressed bales. All criteria to be passed on the same sample. (Samples of compressed bales to be prepared with only 5 blankets folded once more than in normal bales, at 40% compression ratio, and to remain compressed for one week minimum before testing).

Colours	Grey, brown or other dark colours, preferably not died.
Size	150 x 200cm +3%/-1%. To be taken on flat stabilised sample, without folds.
Weight	570 to 670g/m².Weight determined by total weight/total surface.
Thickness ISO 5084	3mm minimum (1KPa on 2000mm²)
Tensile strength ISO13934-1	250N minimum warp and weft
Tensile strength loss after washing ISO13934-1 and ISO 6330	Maximum 5% warp and weft after 3 consecutive machine washing at 30°C and one flat drying.
Shrinkage maxi. ISO 6330	Maximum 5% warp and weft after 3 consecutive machine washing at 30°C and one flat drying.
Weight loss after washing	Maximum 5% after 3 consecutive machine washing at 30°C and one flat drying.
Thermal resistance ISO 11092	Rct= 0.25m².K/W minimum, rounded to the nearest 0.01, passed on samples picked from compressed bales. Mechanical conditioning: after opening of the bale, the blanket shall be dry tumbled in a dryer (500l minimum capacity) without any other load for 15 minutes at a temperature of less than 30°C. Then, the blanket shall be conditioned for at least 24 hours by flat lying at ambient conditions (20°C and 65% Relative Humidity).
Resistance to air flow ISO9237 under 100Pa pressure drop	Maximum 1000 L/m²/s
Finish	Whipped seam at 10mm from the edge with 10 to 13 stitches/10cm or stitched ribbon or hemmed on 4 sides.
Organoleptic test	No bad smell, not irritating to the skin, no dust. 4<pH<9. Free from harmful VOC (Volatile Organic Components). Fit for human use.
Fire resistance ISO12952-1&2, on non-washed sample.	Resistance to cigarette - No ignition
Fire resistance ISO12952-3&4, on non-washed sample.	Resistance to flame - No ignition
Packing	- Bales to be wrapped in a water-tight micro perforated plastic film and covered with a polypropylene or jute woven bag. - Quantity per bale: 20 pieces. - Compressed and strapped with 5 straps (2 lengthwise, 3 crosswise). - Bales dimensions: Length approx. 0.8m, width approx. 0.5m - Height of the bales to be compressed by maximum 40% from free state to final compressed and strapped state. (ex: if the bale is 1m high at free state, it should be compressed to a height of 0.6m at final and strapped state).
Marking on the package	Blankets, 50%wool, 150 x 200cm – 20 pieces. Other markings as specified in contract.
