Benefits of technology

This technology makes it easy for people who want to protect their clothes from harmful insects by adding tiny threads made up mostly of synthetic fibers that are resistant against bacteria or moth bites.

Problems solved by technology

This patented describes different ways for killing unwanted insects called mites while controlling their growth. However, current methods involve applying pesticides onto fabrics like woven materials made from synthetic polymeric material such as nylon-66, which may affect them' ability to transmit germs due to its porous structure. Therefore there needs an improved way to control these types of parasites without adding too much extra steps during manufacturing processes.

Embodiment Construction

[0012] The technical solutions of the present invention will be further specifically described below through examples.

[0013] Example.

[0014] Step 1: Prepare the lotion. The anti-dust mite additive of the present invention has 4 kinds, is dissolved in Tween-80 (sorbitan fatty acid ester polyoxyethylene ether), PEG-400 (polyethylene glycol-400), dodecylbenzenesulfonate respectively Sodium acid (alkyl aryl sulfonate) and water, fully stirred into a uniform emulsion, its formula is shown in Table 1.

[0015] Table 1 The formula table of the anti-dust mite emulsion of the present invention

[0016]

[0017] The second step: blending and spinning. Production of anti-mite viscose filament fibers on a spinning machine in a viscose filament factory. The anti-dust mite emulsion of the present invention is blended online at high speed with viscose dope size filtered through three channels, and then spun after vacuum defoaming. The silk cake after spinning is processed by rinsin
