Fabric layer compounding process and composite flame-retardant mattress cover produced by adopting method

Abstract

The invention relates to a fabric layer compounding process, which is used for compounding a first base material and a second base material, and is characterized in that the first base material and the second base material are laminated in a hot melt adhesive cold compounding manner, the surface of the first base material is sprayed or coated with a flowable hot melt adhesive, the first base material and the second base material are fed into a compression roller group together, the hot melt adhesive on the surface of the first base material faces the second base material, and cold pressing onthe first base material, the hot melt adhesive and the second base material is performed through the compression roller group. According to the invention, the fabric layer and the flame-retardant needled-punched cotton layer are laminated in a hot melt adhesive cold compounding mode, so that the textile fabric layer with the flame-retardant effect and the hand feeling is obtained; and the curing temperature of the hot melt adhesive is lower than the thermal deformation temperature of the flame-retardant needle-punched cotton layer, so that the fluffy change of the flame-retardant needle-punched cotton layer due to over-high temperature of the flame-retardant needle-punched cotton layer in the compounding process is avoided.

Description

technical field [0001] The invention relates to a fabric layer 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 adhesive for composite fabric layers, the hot melt adhesive is coated i...

Problems solved by technology

There are some limitations in the process of compounding the fabric layer in this way: when the flame-retardant needle-punched cotton layer is used as the flame-retardant base material, the flame-retardant 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 flame-retardant needle-punched cotton layer, it will harden and become thinner when the temperature exceeds a certain level, resulting in poor hand feeling of the composite fabric layer
