Textile spacer material, of variable thickness, production process and
uses for it
摘要:
The textile spacer material is a material for replacing foamed substances; it consists of two knitted or woven covering layers that are connected by a pile thread structure. The pile thread structure produces the compressibility known from flexible foams and the large air fraction. The elasticity can be determined by the length and density of the pile threads and the material used. When recyclable materials are used, an environmentally compatible foam substitute can be obtained. Moreover, the textile spacer material can also assume chemical or physical properties through the use of treated starting material or a treatment during or after production and thus be used as a filter or catalyst material, for example.
