TECHNICAL FIELDThe present invention relates to textile field, in particular to a household textile with effect of expelling bedbug obtained by adding plant extracts medicament.
Mosquito is one of the factors disturbing work and rest of people, expelling of mosquito is always extensively concerned by people, products such as mosquito-repellent incense, floral water for expelling mosquito, and paster for expelling mosquito have been come out in succession. How to give textile effect of expelling mosquito is concerned by many researchers. Two main methods for the prevention of mosquito are applied more maturely. The first method is a method to carry out expelling or killing to mosquito existing in the environment, however, this method is not durable and medicament released from aerosol may produce certain harm to human body, therefore, it is not suitable for regular use. The second method is to carry out processing and finishing to textile contacting with human body regularly, make it have more durable effect of preventing mosquito. This method has been proved that it has better effect of preventing mosquito through production practice for long time, and the product produced by the method is highly resistant to washing without toxicity and harm to human body.
Bedbug is a kind of global pest, however, textile for expelling mosquito and preventing insect exist in prior art has no or slight effect to bedbug expelling, and research in respect of textile specialised in expelling bedbug has not been reported.
In order to overcome differences existing in prior art, the objects of the present invention is to utilize different natural plant extract comprehensively and provide a kind of safe and household textile with durable effect of expelling bedbug.
In order to achieve described objects of the invention, the technical solution of the present invention is:
A household textile with effect of expelling bedbug, it is characterised in that the household textile is oven dried after dipping evenly with medicament for expelling bedbug, the medicament for expelling bedbug is made up of eucalyptus extract, peach leaf extract, melia azedarach extract, mint extract, fructus cnidii extract, clove extract, lavender extract, folium artemisiae argyi extract, stabiliser and water.
Preferably, in the medicament for expelling bedbug, eucalyptus extract accounts for 0.1-15 wt % of the total medicament for expelling bedbug, peach leaf extract accounts for 0.1-20 wt % of the total medicament for expelling bedbug, melia azedarach extract accounts for 0.1-10 wt % of the total medicament for expelling bedbug, mint extract accounts for 0.1-5 wt % of the total medicament for expelling bedbug, fructus cnidii extract accounts for 0.1-5 wt % of the total medicament for expelling bedbug, clove extract accounts for 0.1-5 wt % of the total medicament for expelling bedbug, lavender extract accounts for 0.1-5 wt % of the total medicament for expelling bedbug, folium artemisiae argyi extract accounts for 0.1-5 wt % of the total medicament for expelling bedbug, stabiliser accounts for 0.1-0.5 wt %, and water is the rest.
Preferably, the stabilisers of the medicament for expelling bedbug are one or more kinds of UV-P, UV-326, UV-531 and UVP-327.
Preferably, the water is clean river water or tap water; more preferably, tap water.
The extract in the medicament for expelling bedbug is ethanol extract, preferably, extract is solid or concentrated solution, the concentration of the preferable concentrated solution is greater than 90%.
The extract can be commercially available, for instance, the extract sold by Xi'an Yuensun Biological Technology Company.
The extract in the medicament for expelling bedbug can be prepared by conventional method, for instance, obtained by the following preparation methods: taking folium eucalypti coarse powder 1 kg, using 5-fold amount of ethanol to soak for 3 times, merging the soak solution, obtaining concentrated solution of ethanol extract through concentration under reduced pressure, or obtaining solid folium eucalypti extract by vacuum drying the soak solution.
On the other hand, the present invention provides a method for preparation of described household textile with effect of expelling bedbug, specific steps are as follows:
- (1) Preparing the medicament for expelling bedbug;
- (2) Soaking the shell fabric into medicament, bath ratio is 1:20, padding for two times, and the padding ratio is 80%;
- (3) Oven drying the shell fabric processed with medicament for expelling bedbug through oven of 100° C. at 10-60 m/min.
ADVANTAGEOUS EFFECTSIn the present invention, eucalyptus extract, peach leaf extract, melia azedarach extract, mint extract, fructus cnidii extract, clove extract, lavender extract, and folium artemisiae argyi extract are screened out as effective components for expelling bedbug for characteristics of bedbugs, and compounded to process household textile. Synergistic interaction effect is significantly generated comparing with processing by utilising described extracts separately, bedbug can be expelled effectively, meanwhile, plant extract is enable to promote human health to a certain extent, and make the textile provide more effective protection to human body.
Textile shell fabric processed by using described method, medicament for expelling bedbug is formed a layer of film on the surface of fibre, with smell hated by bedbug, and a kind of interference information is generated when contacting bedbug to achieve the object of expelling insects. The effective components for expelling bedbug is enable to penetrate into the inside of fibre with fixed combination, when the effective components on the surface of fibre are losing continuously due to daily use and washing, the effective components in the fibre will migrate to the surface continuously, thereby, ensuring that a certain concentration of the effective components on the surface of fibre can be maintained, therefore, household textile of the present invention is highly resistant to washing, a certain insecticidal efficacy can still be maintained after washing for several times, and the efficacy can be maintained for more than one year.
Specific shell fabric with passing speed and oven drying temperature are applied by the processing method of shell fabric provided by the present invention, which not only makes effective components for expelling bedbug combined with the fabric fibre better, but also prevents too fast degradation of the effective components. On the other hand, the oven drying temperature of the present invention is lower, and it further guarantees that the effective components will not be damaged.
The invention will be described in more detail below with reference to specific embodiments in terms of the effects of medicament for expelling bedbug, and processing method of household textile. It should be understood that the specific embodiment described here is only used for explaining the present invention, but is not limited the thereto. Any modification, equivalent substitution, and improvement made within the true spirit and principle of the invention fall within the scope of the present invention.
