Abstract

The invention discloses a washable waterproof moisture-permeable foam glue laminated fabric and a preparation method thereof. The laminated fabric comprises a modified fabric, foam glue and a waterproof film from bottom to top; the modified fabric is prepared from a cotton fabric, sodium hydroxide, oxalic acid, a first modifier and a second modifier; the foam glue is obtained by foaming with a foaming agent; the waterproof film is prepared from a pretreatment film, polydimethylsiloxane and cyclohexane; and the pretreatment film comprises a first waterproof layer and a second waterproof layer from bottom to top. According to the washable waterproof moisture-permeable foam glue laminated fabric and the preparation method thereof, the technological operation is simple, the component proportion is reasonable, the waterproof film with hydrophobic, waterproof and moisture-permeable properties is laminated on the surface of the modified fabric by utilizing a foam glue laminating method, and the prepared laminated fabric has excellent waterproof and moisture-permeable properties, high hydrophobic property, excellent washing resistance and high practicability.

Description

technical field [0001] The invention relates to the technical field of fabric processing, in particular to a washable waterproof and moisture-permeable foam glue laminated fabric. Background technique [0002] Waterproof and moisture-permeable fabric means that water does not soak into the fabric under a certain pressure, but the sweat emitted by the human body can be transmitted to the outside world through the fabric in the form of water vapor, so as to prevent sweat from accumulating and condensing between the body surface and the fabric to keep the clothing comfortable It is a high-tech, unique functional fabric. The most widely used method at present is to achieve waterproof and moisture-permeable through coating finishing or to achieve waterproof and moisture-permeable through lamination of waterproof and moisture-permeable membrane. [0003] The waterproof and moisture-permeable fabrics on the market today have poor water resistance, and their waterproof and moisture...
