Claims22
A mattress cover formed of a composite material consisting of a nonwoven material and a woven layer, characterized in that the nonwoven material comprises a single nonwoven layer, in which said nonwoven layer and said woven layer are permanently bonded together whilst retaining the flexible character of the woven layer.
A mattress cover according to any one or more of the preceding claims, characterized in that the weight of the nonwoven material is maximally 50 g/m2.
A mattress cover according to any one or more of the preceding claims, characterized in that polypropylene is used as the nonwoven material.
A mattress cover according to any one or more of the preceding claims, characterized in that the single nonwoven layer comprises two separate sub layers of nonwoven materials.
A mattress cover according to any one or more of the preceding claims, characterized in that the woven material has been selected from yarns made from polypropylene, polyethylene, polyacryl, chlorine fibre, aramid, kevlar, elastane, Lyocell (brand), Tencel (brand), jute, bamboo, maize, hemp, ramie, sisal, silk, carbon fibre, glass fibre, banana fibres, bamboo, viscose, polyester, polyamide, acetate, cotton, flax and wool, or a mixture of two or more thereof.
A mattress cover according to any one or more of the preceding claims, characterized in that said nonwoven layer and said woven layer are permanently bonded together by means of a bonding agent applied by means of a scatter coating process.
A mattress cover according to any one or more of the preceding claims, characterized in that the warp density of the woven material is 10-90 yarns/cm.
A mattress cover according to any one or more of the preceding claims, characterized in that the weft density of the woven material is 4-50 shots/cm.
A method of manufacturing a mattress cover as defined in any one or more of the preceding claims, characterized in that the method comprises the following steps:
- a) providing a nonwoven material,
- b) providing a woven material,
- c) applying a bonding agent to the woven material of step b) or to the nonwoven material of step a),
- d) combining the nonwoven material from step a) and the woven material from step b) in such a manner that the bonding agent that has been applied in step c) is present between the two materials, and
- e) treating the assembly thus obtained in such a manner that the mattress cover is obtained, in which the nonwoven layer from step a) and the woven layer from step b) are permanently bonded together whilst retaining the flexible character of the woven layer.
A composite material comprising a woven layer and a finish layer, which finish layer has been applied by means of a scatter coating process.
