Problems solved by technology

These methods are simple in process, but because the anti-mite agent only exists on the surface of the fabric, if the anti-mite agent and the fabric are not firmly combined, the anti-mite agent will easily fall off and be lost after using for a certain period of time or after washing several times, and the anti-mite function of the fabric will be reduced. will weaken, will not last

Embodiment 1

[0031] The bentonite modified by the quaternary ammonium salt used in embodiment 1, its modification method is:

[0032] a. Pulverize, dry and grind the raw bentonite, and then pass through a 400-mesh sieve;

[0033] b. Mix the sieved bentonite with 40% octadecyltrimethylammonium chloride solution, place it in a microwave heater and heat it for 4min, the microwave power is 600W, and the bentonite and octadecyltrimethylammonium The mass ratio of ammonium chloride is 1:4, and the pH of octadecyltrimethylammonium chloride solution is controlled to be 9;

[0034] c. After heating, filter the product with suction, wash once with sodium hydroxide solution with a pH of 9, wash twice with distilled water, freeze-dry the filter cake, activate it at 250°C for 1 hour, and grind it through a 400-mesh sieve. Obtain octadecyltrimethylammonium chloride modified bentonite.

Embodiment 2

[0035] The modification method of embodiment 2 and embodiment 3 is the same as embodiment 1, and the difference is that what embodiment 2 and embodiment 3 use is cetyltrimethylammonium chloride.

[0036] Example 1:

[0037] (1) Prepare ethanol and butanol with a volume ratio of 3:1 into an aqueous solution with a volume fraction of 40%, soak the linen fabric to be treated in the prepared aqueous solution of ethanol and butanol for 30min, and then use oxygen plasma Body treatment, wherein the oxygen plasma treatment conditions are: treatment time 6min, power 100W, pressure 25Pa;

[0038] (2) Soak the pure cotton fabric treated in step (1) with aminopropyltriethoxysilane solution, wherein the solution concentration is 3g / L, and aminopropyltriethoxysilane is 2.4% of the pure cotton fabric quality , the soaking time is 10min, after the end, put the fabric (with a liquid rate of 45%) in an oven at 50°C, and pre-dry for 30min;

[0039] (3) Dip the pre-dried fabric into anti-mite f...

Embodiment 3

[0047] (1) Prepare ethanol and butanol with a volume ratio of 4:1 into an aqueous solution with a volume fraction of 50%, soak the pure cotton fabric to be treated in the prepared aqueous solution of ethanol and butanol for 40min, and then use oxygen Plasma treatment, wherein the conditions of oxygen plasma treatment are: treatment time 7min, power 150W, pressure 35Pa;

[0048] (2) Soak the pure cotton fabric treated in step (1) with aminopropyltriethoxysilane solution, wherein the solution concentration is 4g / L, and aminopropyltriethoxysilane is 2.7% of the pure cotton fabric quality , soaking time 13min, after the end, put the fabric (with liquid rate 45%) in the oven at 45 ℃, pre-baked for 40min;

[0049] (3) Dip the pre-dried fabric into anti-mite finishing solution (evenly dispersed by ultrasonic) for padding, the bath ratio is 1:30, wherein the anti-mite finishing solution includes polyurethane adhesive, nano-silver and quaternary ammonium salt modification The concentr...

Abstract

The invention discloses a preparing method of an antibacterial anti-mite fabric. The method includes the following steps of firstly, soaking a fabric with an ethyl alcohol and butyl alcohol mixed water solution, and processing the fabric through plasmas after processing is completed; secondly, preprocessing the fabric processed in the first step through a silane coupling agent solution, and subsequently conducting pre-baking; thirdly, soaking the pre-baked fabric in anti-mite finishing liquor for padding, wherein the anti-mite finishing liquor comprises an adhesive, an anti-mite agent and a bentonite modified by quaternary ammonium salt; fourthly, drying the padded fabric to obtain the antibacterial anti-mite fabric. The anti-mite fabric prepared and obtained through the method has more hydroxyl groups on the surface after being processed through the plasmas, the binding force between a silane coupling agent and the fabric is improved, the anti-mite agent attached to the surface of thefabric is not prone to loss, and the anti-mite function of the fabric is effectively prolonged.

Description

technical field [0001] The invention belongs to the field of functional textile fabrics, and in particular relates to a preparation method of an antibacterial and anti-mite fabric. technical background [0002] Mites are tiny pests invisible to the naked eye. There are more than 50,000 species of mites found in the world. Mites are ubiquitous in the home environment, such as bedding, carpets, cushions, clothing, plush toys, etc. With the help of fungi, they feed on dander that falls off from the human body. Mites reproduce quickly and are difficult to eliminate. Mites are suitable for survival under the conditions of temperature 20-30°C and relative humidity greater than 55%. Therefore, equipped with air conditioners, carpets, and modern living rooms with better airtightness provide them with a good living environment. Mites are very closely related to human health. For example, leather mites, chiggers, sarcoptic mites, demodex mites, acaroid mites, dust mites, etc. can bi...
