Laminating process for flame-retardant fabric, and laminated flame-retardant mattress cover produced by laminating process

Abstract

The invention relates to a flame-retardant fabric laminating process which is used for laminating a first base material and a second base material. The laminating process is characterized in that thefirst base material and the second base material are laminated in a hot-melt adhesive cold laminating manner, concretely the surface of the first base material is sprayed or coated with a flowable-state hot melt adhesive; the first base material and the second base material are jointly sent into a compression roller set; the hot melt adhesive on the surface of the first base material faces the second base material; and cold pressing is carried out on the first base material, the hot melt adhesive and the second base material through the compression roller set. The laminating process has the advantages that a flame-retardant fabric and a needle-punched cotton layer are laminated in a hot-melt adhesive cold laminating mode, so that the textile fabric with a flame-retardant effect and good handfeel is obtained. Due to the fact that the curing temperature of the hot-melt adhesive is lower than the heat deformation temperature of the needle punched cotton layer, the phenomenon that the needle punched cotton layer is fluffy due to too high temperature in the laminating process is avoided.

Description

technical field [0001] The invention relates to a flame-retardant fabric composite process, and also relates to a composite flame-retardant mattress cover produced by the method. Background technique [0002] In order to prevent the occurrence of fire, in addition to taking fire prevention measures, textiles with flame retardant properties, such as flame retardant cloth and flame retardant work clothes, can also be used to delay the expansion of the fire and give people time to evacuate or take measures to extinguish the fire. Therefore, the development and innovation of flame retardant technology is particularly important. [0003] In the development process of the current textile flame-retardant materials, more emphasis is placed on flame-retardant performance and cost factors, while ignoring the performance requirements that the textile itself should have. [0004] For example, in the process of using hot-melt adhesives for composite fabrics, the hot-melt adhesives are c...

Problems solved by technology

There are some limitations in the process of composite fabrics in this way: when the needle-punched cotton layer is used as the base material in the flame-retardant composite fabric, the needle-punched cotton layer and the fabric layer are sent to the pressing roller group for heating and extrusion , and due to the material characteristics of the needle-punched cotton layer, it will become hard and thin when the temperature exceeds a certain level, resulting in poor hand feeling of the composite fabric
