Problems solved by technology

This method can give consumers intuitive color development on non-woven fabric products, but it can neither indicate the concentration of biocide on the non-woven fabric nor judge the anti-microbial performance of the non-woven fabric. It is a misleading method. chromogenic technology; 2) a cationic chromogenic agent configured with antimicrobial materials, but the chromogenic technology is susceptible to interference from non-woven fabrics
For example, acid and alkali residues or changes in hydrophilicity on non-woven fabrics can cause color development without antimicrobial materials, while in some cases non-woven fabrics with antimicrobial properties cannot develop color
In addition, the existing general color indicator is obtained by dissolving the color indicator, and there are still defects such as the color cannot be developed immediately when it is dropped on the non-woven fabric, the color is unstable, and there is no detailed comparison between antibacterial and non-antibacterial.

Embodiment 1

[0024] To make a non-woven fabric with antimicrobial function, take 0.1% acetic acid, 2% single-chain quaternary ammonium salt, 1% moisture-absorbing and sweat-wicking agent, and surplus water in percentage by weight, stir and fully mix. Use the roller coating equipment to adjust the roller coating speed, and the obtained mixed solution is attached to the two surfaces of the non-woven fabric substrate. The obtained non-woven fabric substrate attached with the mixed solution is dried at 120°C until the non-woven fabric substrate is completely dry to obtain a non-woven fabric with antimicrobial function. The moisture-absorbing and sweat-wicking agent is from Shanghai Purcell Technology Co., Ltd., brand: PRO-2361.

[0025] To prepare a color developer, weigh 0.3 parts by weight of thymol blue, 0.3 parts of bromophenol blue, 0.3 parts of methyl orange, 80 parts of alcohol, 8 parts of polyoxyethylene ether, and 6 parts of distilled water at 50 ° C. After mixing and stirring under ...

Embodiment 2

[0028] To make a non-woven fabric with antimicrobial function, take 0.16% by weight of citric acid, 2.4% of polyhexamethylene monoguanidine PHMG, 1.5% of moisture-absorbing and sweat-wicking agent, and the rest of water, stir and fully mix evenly. The obtained mixed solution is attached to both surfaces of the non-woven fabric substrate by spraying with a spray gun. The obtained non-woven fabric substrate attached to the mixed solution was dried at 120°C until the non-woven fabric substrate was completely dry to obtain a non-woven fabric with antimicrobial function.

[0029] Prepare the color developer, take by weight 0.4 parts of thymol blue, 0.3 parts of bromophenol blue, 0.45 parts of methyl orange, 80.5 parts of alcohol, 9 parts of polyoxyethylene ether, 5 parts of diethylene glycol, 1 part of propylene glycol and 7 parts of distilled water were mixed and stirred at 50° C. until they were fully dissolved, and then aged at room temperature for 4 hours to obtain a primary li...

Embodiment 3

[0032] To make a non-woven fabric with antimicrobial function, take 0.2% acetic acid, 3% polyhexamethylene biguanide PHMB, 2% moisture-absorbing and sweat-wicking agent, and the remainder water in percentage by weight, stir and fully mix evenly. The obtained mixed solution was attached to both surfaces of the non-woven fabric substrate by a brush coating method. The obtained non-woven fabric substrate attached with the mixed solution is dried at 120°C until the non-woven fabric substrate is completely dry to obtain a non-woven fabric with antimicrobial function.

[0033] Prepare the color developer, take by weight 0.6 parts of thymol blue, 0.3 parts of bromophenol blue, 0.6 parts of methyl orange, 80.8 parts of alcohol, 10 parts of polyoxyethylene ether, 8 parts of diethylene glycol, 2 1 part of propylene glycol and 8 parts of distilled water were mixed and stirred under the condition of 50° C. until fully dissolved, and aged at room temperature for 4 hours to obtain the prima...

Abstract

The invention relates to a visual color development method of a non-woven fabric with an antimicrobial function, which is characterized by comprising the following steps: S1) preparing a non-woven fabric with an antimicrobial function; S2) preparing a color developing agent; S3) dripping the color developing agent prepared in the step S2) on the non-woven fabric with the antimicrobial function prepared in the step S1), wherein the color developing agent and positive ions generate a color developing reaction. According to the visual color development method of the non-woven fabric with the anti-microbial function, through the prepared anti-microbial non-woven fabric, whether the produced non-woven fabric has the antimicrobial property or not can be quickly, obviously and stably judged, a non-woven fabric producer is helped to timely and accurately control the product quality, and a consumer can be helped to quickly and accurately judge whether a purchased product has the antimicrobial property or not. In the past, the antibacterial and antimicrobial effects are difficult to experience and invisible, and the visual color development method meets the antibacterial and antimicrobial health requirements which can be displayed for the user to experience.

Description

technical field [0001] The invention belongs to the technical field of production of functional nonwoven fabrics, and in particular relates to a color development method of an antimicrobial nonwoven fabric with a visual color development function. Background technique [0002] With the frequent occurrence of public health incidents, especially the SARS incident in 2003 and the occurrence of new pneumonia in 2020, people's pursuit of a safer and more comfortable living environment and the risk of microbial infection have become a long-term contradiction. The demand for non-woven products is increasing to meet their requirements for clean and healthy life. Nonwovens are commonly used in the manufacture of disposable or non-disposable products such as diapers, wet wipes and feminine hygiene products, and are generally produced from petrochemical materials such as polyolefins, polyesters, polylactic acid, rayon or natural materials such as cotton fibers. [0003] Due to the cha...
