Problems solved by technology

Wearing fabrics are designed and produced according to wearing characteristics, which can meet people's wearing requirements, but cannot meet the higher requirements of the new flexible fabric sensor for fabric base materials; decorative textiles focus on the appearance and decorative effects, basically no Wearable and good mechanical properties; technical textiles may have good mechanical properties but not wearable
Therefore, the fabric materials on the market limit the performance and application range of flexible fabric sensors.

Embodiment 1

[0032] see Figure 1 to Figure 5 , This embodiment provides a low-relaxation and low-hysteresis elastic knitted fabric for sensors, which is processed by a circular weft knitting machine, and the fabric structure is plain weave with spandex plating. Spandex as ground yarn, namely figure 1 Among them, the black line 1 is spandex filament as elastic yarn; nylon filament is plating yarn, that is figure 1 Among them, the white thread 2 is a nylon filament as a non-elastic yarn; the nylon filament 2 is located on the surface of the fabric, and the spandex filament 1 is located inside the fabric. Among them, nylon filament 2 has a linear density of 70D, and spandex filament 1 has a linear density of 40D (Nylon filament 2 uses Tactel nylon filament, and spandex filament 1 uses Lycra spandex filament); the fiber composition is 83% by weight of nylon, and the weight of spandex is 83%. Percentage 17%; the square meter weight of the fabric is 200g / m 2 , fabric width 135cm, thickness 0...

Abstract

The invention provides a method for manufacturing elastic fabrics for low-relaxation and low-hysteresis sensors; the elastic fabrics are processed by combining elastic yarns and non-elastic yarns; wherein, the elastic yarns can be spandex filaments, rubber filaments silk or polyolefin fiber filament, the non-elastic yarn can be acetate fiber filament or its spun yarn, nylon, polyester, aramid fiber, polyimide. The invention is designed according to the characteristics of the fabric sensor and wearable characteristics, and can meet the mechanical performance requirements of the fabric sensor for the fabric base material, thereby improving the measurement range, sensitivity, linearity, response rate and fatigue resistance of the fabric sensor, and reducing Test error and hysteresis characteristics.

Description

technical field [0001] The invention belongs to the combined field of textile and smart wear, and in particular relates to a preparation method of an elastic fabric for sensors with low relaxation and low hysteresis properties. Background technique [0002] A sensor is a detection device that can convert the measured signal into an electrical signal according to a certain rule, and generally includes a sensitive element and a conversion element. Flexible fabric sensor is a new type of sensor developed in recent years. The wearable sensor based on fabric can be widely used in wearable electronic devices that have become popular in recent years. It can be used to measure a wide range of strains that traditional sensors cannot work. Such as a flexible fabric strain sensor disclosed in US Patent (US 8191433) and Chinese Patent (CN 101598529). [0003] As a flexible fabric sensor, the fabric substrate is a key component of the sensitive element of this type of sensor, which can ...
