Abstract

The invention relates to a making method of a high-elasticity luminous elastic fabric, and belongs to the field of processing and making of functional textiles. The product is obtained through the steps of high-elasticity polyurethane prepolymer synthesis, high-elasticity polyurethane emulsion preparation, luminous material preparation, high-elasticity luminous polyurethane rubber paste preparation and high-elasticity luminous elastic fabric making. According to the high-elasticity luminous elastic fabric obtained through the making method, on the condition that the elasticity of an original fabric is well kept, the luminous visible property is given to the fabric; meanwhile, the obtained high-elasticity luminous elastic fabric is dry and comfortable in hand feeling and good in friction fastness and washing fastness and meets various environmental protection standards.

Description

technical field [0001] The invention relates to a preparation method of a high-elastic luminous elastic fabric, which belongs to the field of processing and manufacturing of functional textiles. Background technique [0002] Luminous fabrics have also been widely used in recent years because of their luminous properties in dark environments, such as in transportation, entertainment, night work and special clothing. Chinese patents CN1333402A and CN102154824B all disclose a production method of luminous fabrics, but the luminous fabrics produced by them are hard to the touch, have poor washing resistance and abrasion resistance, and the treated fabrics cannot maintain the original elastic fabrics. The elastic requirements affect the further development and application of luminous textiles. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the existing luminous textiles that cannot maintain the elasticity requirements...
