Problems solved by technology

[0004] The present invention provides a method suitable for durable mosquito repellent finishing of fabrics, which mainly solves the problem of thermal baking in the prior art, so that the mosquito repellent in the mosquito repellent microcapsules volatilizes and even destroys the wall material of the capsule, resulting in repellent Leakage of mosquito repellent, these factors will reduce the durability of mosquito repellent finishing, and heat baking also consumes a lot of energy, causing technical problems such as air pollution

Embodiment 1

[0018] Embodiment 1: A kind of method of this example is applicable to the durable mosquito repellent finishing of fabric, and its method is: use the coating slurry that contains ultraviolet curing adhesive and photoinitiator, after fabric is through coating, through drying, then UV curing, and finally get a mosquito repellent fabric with good durability.

[0019] Use this method to carry out mosquito repellent finishing on pure cotton fabrics. The coating slurry component is mosquito repellent microcapsule powder: 50g / kg, binder: UCECOAT7849 200g / kg, photoinitiator: Runtecure1265 20g / kg, thickener PTF : 3g / kg, dried at 60°C for 3 minutes after coating, and finally cured for 4 minutes under a 100W / cm ultraviolet lamp. The distance between the mercury lamp and the fabric was 50m to obtain a mosquito repellent fabric.

[0020] The preparation of mosquito repellent microcapsules: After emulsifying the mosquito repellent, adjust the pH of the emulsified liquid to 4-5, add trihydro...

Embodiment 2

[0022] Embodiment 2: A kind of method that this example is applicable to the durable mosquito repelling finishing of fabric, its method is: the coating slurry that will contain ultraviolet curing adhesive and photoinitiator is coated on the fabric, then dry, finally ultraviolet After curing, a mosquito repellent fabric with good durability can be obtained.

[0023] Coating slurry components are mosquito repellent microcapsules: 50g / kg, binder UCECOAT7849: 200g / kg, photoinitiator Runtecure1265: 20g / kg, thickener PTF: 5 g / kg, after coating at 60°C Dry for 3 minutes, and finally cure for 3 minutes under a 100W / cm ultraviolet lamp. The distance between the mercury lamp and the fabric is 50mm to obtain a mosquito repellent fabric.

[0024] The preparation of mosquito repellent microcapsules: After emulsifying the mosquito repellent, adjust the pH of the emulsified liquid to 4-5, add trihydroxymelamine resin prepolymer dropwise according to the core-to-wall ratio of 1:1, heat up to ...

Abstract

The invention relates to the field of after-finishing of textile products, in particular to a method suitable for long-lasting mosquito repelling finishing of textiles. The invention mainly solves the following problems in the prior art: the mosquito repelling substance in mosquito repelling microcapsules volatilizes even destroys the walls of the microcapsules during heat baking process, resulting in leakage of mosquito repellant and reduction of durability of mosquito repelling finishing, and heat baking consumes a large amount of energy and causes air pollution. The method comprises the steps of coating the coating slurry containing an ultraviolet curing adhesive and a photoinitiator on textile, drying and finally performing ultraviolet curing.

Description

technical field [0001] The invention relates to the field of finishing of textiles, in particular to a method suitable for durable mosquito repelling finishing of fabrics. Background technique [0002] Mosquito repellents occupy a major place in medical insect control. Mosquitoes spread diseases by stinging and sucking blood. Even if they have no disease-transmitting effect, they constitute serious harassment to people and easily cause skin diseases. People who live, work, and travel in environments such as forests, grasslands, and wilderness use mosquito repellents as the main means of protection. DEET is the most effective broad-spectrum mosquito repellent in practical use in the past 40 years. The mosquito repellents equipped in the United States, Singapore, Thailand and other countries also use DEET as the main ingredient. Although adding DEET to textiles can achieve long-lasting repellent protection, direct addition of DEET does not give long-lasting repellent effect...
