Abstract

The invention discloses a washable waterproof moisture-permeable foam adhesive laminated fabric and a preparation method thereof. The laminated fabric comprises a modified fabric, a foam adhesive anda 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; wherein the foam glue is obtained byfoaming a foaming agent; the waterproof membrane is prepared from a pretreatment membrane, polydimethylsiloxane and cyclohexane; the pretreatment film comprises a first waterproof layer and a second waterproof layer from bottom to top. The invention discloses a washable waterproof moisture-permeable foam adhesive laminated fabric and a preparation method thereof. The preparation method is simple in process operation and reasonable in component proportion, the waterproof film with hydrophobic, waterproof and moisture-permeable performance is attached to the surface of the modified fabric through a foam glue attaching method, and the prepared attached fabric has excellent waterproof and moisture-permeable performance, high hydrophobic performance, 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 and a preparation method thereof. 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, ...
