Problems solved by technology

[0005] A drawback of currently applied fungicides is that repeated treatments at regular intervals are required for continuous control of HDM
Moreover, the fungicide itself is a toxic substance. For this reason, the use of such substances in households has been restricted at present.

Embodiment Construction

[0013] This example demonstrates the fungicidal activity of acrylic fibers incorporating a fungicide against Aspergillus creeper and the use of such fabrics in the control of HDM.

[0014] Using a method similar to that disclosed in Example 1 of GB-A-2,309,461, an acrylic fiber was prepared containing 0.4% of Tinea (methyl-3-tolylthiocarbamic acid-2-naphthyl ester). Such fibers are commercially available from Courtaulds Fibers (Holdings) Limited under the trade name AMICOR AF. Acrylic fibers without fungicide (commercially available under the COURTELLE tradename from Courtaulds Fibers (Holdings) Limited) were used as a control. Adopt the parallel streak method (parallel streak method) disclosed in Example 1 of GB-A-2,309,461, and use about 3×10 6 Spores / ml of culture of Aspergillus creeper (IMI 094150) were used to determine the antibacterial activity of the fibers. The test pieces were incubated at 25°C for 4 days. Determining the width of the zone of inhibition of fungal ...

Abstract

Polymeric articles such as fibres and foams having incorporated therein a chemical compound which has antifungal activity against fungi of the groups Aspergillus glaucus and / or A. restrictus are useful in controlling house dust mites and bedmites Dermatophagoides spp.

Description

technical field [0001] The present invention relates to a method for controlling house dust mites and bed mites (hereinafter referred to as HDM). HDM is a typical dust mite genus (dermatophagoides spp.), a particularly obvious one is the house dust mite (D. pteronyssinus) . Background technique [0002] The HDM's main food is dead dander (hair dander). Humans continue to shed such detritus in considerable quantities. HDMs multiply especially in bedding, fillings including pillows and bedding, and in cushioned articles and fibrous floor coverings. HDM are drought-loving organisms that do not require liquid water, and they can survive in the absence of water. They require a high humidity environment, requiring around 70-80% relative humidity to survive. They absorb little water from the air and can effectively rely on their food as a water source. HDM typically excretes about 20 fecal particles per day. The particles are very dry and brittle, about 30 microns in size. ...
