Example Embodiment

[0028] Example 1

[0029] The preparation method of silk artificial muscle includes the following steps:

[0030] Step 1: Soak the commercially purchased cocoon silk in a 0.1mol / L sodium hydroxide solution for degumming, and the soaking time is 36h;

[0031] Step 2: Wash the degummed silk obtained in the step 1 with deionized water and dry at room temperature;

[0032] Step 3: Preparation of silk yarn

[0033] Spinning the 5 degummed silks in the step 2 with a twist direction of "Z" twist, a twist of 6000 revolutions / meter, and a yarn diameter of 50 μm;

[0034] Step 4: Hang a 3g weight from the middle of the yarn in step 3, and fold it in half to obtain a self-balanced double-folded yarn;

[0035] Step 5: Wind the half-folded yarn obtained in the step 4 around a 0.5mm mandrel with a coil spacing of 1.5mm, and the winding direction is the same as the spinning twist direction;

[0036] Step 6: Put the artificial muscle obtained in step 5 together with the mandrel into a drying box for heat ...

Abstract

The invention discloses a preparation method of a smart fabric based on silk artificial muscles. By the aid of the hygroscopicity of silk, the silk is prepared into the humidity-sensitive silk artificial muscles, and the silk artificial muscles are knitted into the fabric to achieve smart functions. The preparation method includes the processes of silk yarn preparation, silk artificial muscle preparation, heat setting and the like, finally, the obtained silk artificial muscles and silk yarns are subjected to plain weaving to obtain the smart fabric, warp yarns are silk artificial muscle arranged yarns, and weft yarns are degumming silk arranged yarns. The silk artificial muscles are sensitive to environment humidity, can spontaneously sense humidity change and respond, and can absorb waterand contract lengths in a humid environment, and the lengths of the silk artificial muscles are restored in a dry environment. Therefore, when a human body with a large sweating quantity needs timelysweat discharge, the fabric prepared from the artificial muscles can sense sweat and facilitate sweat discharge of the human body by length contraction, and human body humidity and heat management isrealized. After the sweat is discharged, the length of the fabric restores when the human body is dry, and more comfort is provided for a wearer.

Description

technical field [0001] The invention belongs to the technical field of intelligent fabrics, and relates to a moisture-sensitive intelligent fabric, in particular to a preparation method of an intelligent fabric based on silk artificial muscles. Background technique [0002] Smart fabrics have always been one of the important areas of scientific research and textile research, leading the fourth textile industrial revolution. The global smart textile industry is estimated to be worth more than $130 billion by 2025. By integrating artificial muscles sensitive to environmental stimuli into fabrics, multiple functionalities of fabrics can be realized, including providing energy storage, energy harvesting, self-cleaning, color changing, luminescence, managing human body temperature and humidity regulation, etc. Especially for moisture-sensitive textiles, the humidity and thermal management of the human body can be realized by sensing sweat and rain to adjust the macroscopic lengt...
