Embodiment 1

[0048] This embodiment provides a method for preparing an electrostatically loaded polyester woven fabric material with a bonding layer, a conductive layer and an electrical storage layer. The specific steps are as follows:

[0049] Step 1: Combine layer generation:

[0050] a) Pre-cleaning: wash 300-mesh polyester woven fabric twice in pre-cleaning bath acetone (analytical pure) to remove surface impurities, and then dry naturally at room temperature for 15 minutes;

[0051] b) Preparation of dopamine treatment bath: prepare a buffer solution with a concentration of 10 mM tris-HCl (Tris-HCl), adjust the pH to 8.5; add dopamine hydrochloride and stir to dissolve, and prepare a concentration of 2 g / L dopamine hydrochloride solution treatment bath;

[0052] c) Bonding layer formation: place the pre-cleaned 300-mesh polyester woven fabric in a dopamine hydrochloride solution treatment bath at 30°C with a solid-to-liquid ratio of 1:2, treat it for 30 minutes, wash it in three wat...

Embodiment 2

[0061] This embodiment provides a preparation method of a silver polyester blended woven fabric material with a binding layer, a conductive layer and a storage layer for electrostatic loading, and the specific steps are as follows:

[0062] Step 1: Combine layer generation:

[0063] a) Pre-cleaning: wash the silver polyester blended woven fabric three times in deionized water in the pre-cleaning bath to remove surface impurities, and then dry naturally at room temperature for 10 minutes;

[0064] b) Preparation of dopamine treatment bath: prepare a buffer solution with a concentration of 15mM Tris-HCl, adjust the pH to 8.5; add dopamine hydrochloride and stir to dissolve, and prepare a concentration of 3g / L dopamine hydrochloride solution treatment bath;

[0065] c) Bonding layer generation: place the pre-cleaned silver polyester blended woven fabric in a dopamine hydrochloride solution treatment bath at 40°C with a solid-to-liquid ratio of 1:3, treat for 40 minutes, wash in ...

Abstract

The invention discloses a method for preparing an electrostatically loaded multi-layer coated yarn or fabric material, which is characterized in that it comprises the following steps: 1) placing the yarn or fabric base material in a dopamine treatment bath for treatment, and cleaning after treatment, Dry to obtain the yarn or fabric base material with polydopamine binding layer; 2) place the yarn or fabric base material with polydopamine binding layer in the silver ammonia solution, then add the reducing agent solution dropwise to the silver ammonia solution for treatment , cleaning after treatment, drying to obtain yarn or fabric base material with binding layer and conductive layer; Rollers remove excess solution and dry to obtain a yarn or fabric base material with a bonding layer, a conductive layer and a storage layer. On the basis of the basic decorative and beautifying functions of textiles, the invention further adds additional functions to promote the functional development of textiles.

Description

technical field [0001] The invention belongs to the field of functional treatment of textiles, in particular to a method for preparing multi-layer coated yarns and fabric materials with high electrostatic load. Background technique [0002] With the continuous development of my country's industrialization, people's requirements for textile materials are getting higher and higher, and a single textile structure material can no longer meet people's needs. More functionality. Static-loaded textile materials have broad application prospects in functional textiles, decorative textiles, industrial textiles, military, aerospace electronics, medical, biological, smart wearable and other fields. Traditional static-loaded textile materials are basically inorganic, metal or ceramic materials , it has high rigidity, low softness, poor washing resistance, weak electrostatic loading capacity, and low loading efficiency. At present, there are still few researches on textile materials with ...
