Textile formaldehyde and pH value detection device

Abstract

The invention relates to the field of textile detection, in particular to a textile formaldehyde and pH value detection device which comprises a box body, a first detection mechanism used for detecting the pH value and a second detection mechanism used for detecting the formaldehyde content, the first detection mechanism is arranged on the box body, and the second detection mechanism is arranged in the box body. According to the textile formaldehyde and pH value detection device, a clamping mechanism is arranged below a sealing plate, and a threaded rod and a rubber disc are combined, so that pH test paper can be quickly extruded and fixed on a first fixing plate, the pH value can be quickly detected, meanwhile, the pH test paper can be quickly replaced, an air bag is arranged in a box body, and the air bag is convenient to replace; the air bag is arranged on the box body, the air cylinder is arranged on the box body, the textile can be placed in the air bag, then the air cylinder is utilized to circularly extrude the textile, formaldehyde in the textile can be quickly and thoroughly released, the formaldehyde detection efficiency and accuracy can be improved, and the device is very convenient to use.

Description

technical field [0001] The invention relates to the field of textile detection, in particular to a textile formaldehyde and pH value detection device. Background technique [0002] The quality inspection of textiles is mainly the detection of harmful chemical substances, including lead content detection, formaldehyde content detection, harmful substance detection, pH value detection, etc. During the production process, textiles have to go through multiple processing procedures such as pre-treatment, printing and dyeing, and post-finishing. Lead to the presence of residual formaldehyde in textiles. For example, in the printing and dyeing process of textiles, in order to improve the color fastness, color fixing treatment is required. Commonly used are cationic resin-type color fixing agent Y and color fixing agent M, which are condensation products of dicyandiamide and formaldehyde and contain high free formaldehyde. Therefore, formaldehyde will be contained in dyed fabrics ...

AI Technical Summary

Problems solved by technology

[0003] The currently used textile formaldehyde and pH value detection device is inconvenient to quickly and quickly replace the pH test paper, resulting in slow pH detection and low efficiency. At the same time, it is not convenient for the formaldehyde on the textile to be released quickly and completely, which seriously affects the formaldehyde detection. Efficiency and precision, extremely inconvenient to use
