Embodiment 1

[0026] The toughening modification treatment method of polyurethane sponge under the ionic liquid condition of embodiment 1 (abbreviated as S1, the following embodiments are the same) comprises the following steps:

[0027] 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 the low-temperature ammonia gas for plasma treatment, apply the voltage discharge frequency of 13.75MHz, and the power of 100W , the processing time is 20s;

[0028] S2: Configure carboxylated chitosan treatment solution: the main components of carboxylated chitosan treatment solution are carboxylated chitosan, urea, ionic liquid and water;

[0029] S3: immerse the polyurethane sponge in the carboxylated chitosan 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...

Embodiment 2

[0034] The difference between embodiment 2 and embodiment 1 is:

[0035] S1: Put the polyurethane sponge in the alkali pretreatment solution for immersion treatment, heat up the pretreatment for 5 hours, wash it with water, dry it, put the polyurethane sponge in the low-temperature ammonia gas for plasma treatment, apply the voltage discharge frequency of 13.75MHz, and the power of 150W , the processing time is 50s;

[0036] S2: Configure carboxylated chitosan treatment solution: the main components of carboxylated chitosan treatment solution are carboxylated chitosan, urea, ionic liquid and water;

[0037] S3: soak the polyurethane sponge in the carboxylated chitosan treatment solution for at least two padding treatments, raise the temperature to 60°C, and keep it warm for 2.5 hours, take out the polyurethane sponge, and roll off the excess sol;

[0038] S4: Wash the sponge obtained in S3 with ethanol and water in sequence, and dry at 140° C. to obtain a toughened polyurethane...

Embodiment 3

[0041] The difference between embodiment 3 and embodiment 2 is:

[0042] S1: Put the polyurethane sponge in the alkali pretreatment solution for immersion treatment, heat up the pretreatment for 3.5 hours, wash it with water, dry it, put the polyurethane sponge in the low-temperature ammonia gas for plasma treatment, apply a voltage discharge frequency of 13.75MHz, and the power is 125W, processing time is 35s;

[0043] S2: Configure carboxylated chitosan treatment solution: the main components of carboxylated chitosan treatment solution are carboxylated chitosan, urea, ionic liquid and water;

[0044] S3: immerse the polyurethane sponge in the carboxylated chitosan treatment solution for at least two padding treatments, raise the temperature to 50°C, and keep it warm for 1.5 hours, take out the polyurethane sponge, and roll off the excess sol;

[0045] S4: Wash the sponge obtained in S3 with ethanol and water in sequence, and dry at 130° C. to obtain a toughened polyurethane...

Abstract

The invention discloses a toughened sponge composite air layer fabric. The air layer fabric comprises a surface layer, a core layer and an inner layer. The inner layer is formed by stitching or bonding; the core layer is made of polyurethane sponge. The toughening treatment process of polyurethane foam comprises the steps of: alkali pretreatment, low-temperature plasma pretreatment, and treatment by chitosan treatment fluid containing ionic liquid. The air layer fabric using the above toughened sponge as the composite air layer has excellent rebound performance; and the chitosan formed by toughening process has the advantages of water insolubility, high tensile strength, improved hydrophilic properties, and is conducive to improving the moisture vapor permeability of the fabric.

Description

technical field [0001] The invention relates to the technical field of fabrics, in particular to a toughened sponge composite air layer fabric. 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] However, in actual u...
