Embodiment 1

[0025] Embodiment 1 (abbreviated as S1, the following embodiments are the same) The method for toughening the air layer fabric with a sponge layer includes the following steps:

[0026] S1: Put the polyurethane sponge in the alkali pretreatment solution for immersion treatment, heat up the pretreatment for 2 hours, wash it with water, dry it, put the polyurethane sponge in low-temperature ammonia gas for plasma treatment, apply a voltage discharge frequency of 13.75MHz, and a power of 100W. The processing time is 20s;

[0027] S2: Configure carboxylated chitosan sol treatment solution: the main components of carboxylated chitosan sol treatment solution are carboxylated chitosan, organic acid, titanium dioxide and water;

[0028] S3: immerse the polyurethane sponge in the carboxylated chitosan sol treatment solution for at least two padding treatments, raise the temperature to 40° C., keep warm for 0.5 hours, take out the polyurethane sponge, and roll off the excess sol;

Abstract

The invention discloses a toughening treatment method for a sponge layer used for an air layer fabric. The toughening treatment method comprises the steps of pre-treating the sponge layer respectively with an alkaline liquid and low-temperature plasma, and treating the sponge layer with gel. In the method, roughness of surface of polyurethane sponge is increased, so that the crosslinking reaction area between the gel and the polyurethane sponge is increased in the subsequent steps. During the plasma treatment, under high energy particles bombardment, the surface of the polyurethane sponge is etched further, while large quantity of amino acids are grafted to the surface of the polyurethane sponge. A Ti-O network structure in carboxylated chitosan and gel is deposited on the surface of fibers to form an interpenetrating hybridized thin film, so that toughness and rebounding property of the polyurethane sponge are improved.

Description

technical field [0001] The invention relates to the technical field of fabrics, in particular to a sponge layer toughening treatment method for air layer fabrics. Background technique [0002] At present, the air layer fabrics on the market mainly include the following three types: one is a kind of textile accessories. The pure cotton fabric is soaked in a chemical solution. After soaking, the surface of the fabric is covered with countless extremely fine hairs. Form an extremely thin air layer on the surface of the fabric; the second is to sew two different fabrics together, and the gap in the middle may be filled with elastic curly fibers; the third is to combine the upper and lower surfaces of the sponge sheet with wool, cashmere, cotton, silk, etc. Quality, chemical fiber fabrics, etc. are bonded by adhesives. Because the porous sponge has good water absorption and light weight, it can have the same or similar warmth retention effect as the above two fabrics. [0003] H...
