Embodiment 1

[0023] Example 1. Preparation of polyethylene insect-proof cloth and detection of pyrethroid dose.

[0024] Cloth weight 70g / m 2 , the target amount of deltamethrin is 100mg / m 2 .

[0025] Liquid composition:

[0026] 10% Deltamethrin EC 0.01L

[0027] Add water to 5.0L

[0028] Put 100g of polyethylene cloth into the dyeing solution (100g of cotton cloth is put into the blank control test at the same time), the dyeing solution circulates continuously from bottom to top, and the temperature rises at 2°C per minute, until the water temperature is 80-85°C, keep warm for 30min. Tumble dry in a centrifuge.

[0029] Pyrethrin polyester

Embodiment 2

[0030] Example 2. Preparation of insect repellent polyacrylonitrile yarn.

[0031] The material is 16.8tex×4 polyacrylonitrile yarn, the target content of deltamethrin is 0.18%, the target content of cyhalothrin is 0.36%, and the dyeing rate is 75%.

[0032] Liquid composition:

[0033] 10% Deltamethrin EC 0.25L

[0034] 20% Cyhalothrin EC 0.25L

[0035] Acetic acid 1.0L

[0036] Add water to 50L

[0037] Dip 10kg of 16.8tex×4 polyacrylonitrile yarn into the dye solution, adjust the pH to 4-5, circulate the dye solution continuously from bottom to top, raise the temperature by 1°C per minute, until the water temperature reaches 95-100°C, and hold for 30 minutes. After dyeing, the yarn is dried in a centrifuge, and the remaining liquid after the centrifuge is recycled, and then added with a new dyeing solution for reuse. After the yarn is spun dry, it enters the dryer to dry. This polyacrylonitrile yarn is used to weave blankets or carpets and is resistant to mites and fl...

Embodiment 3

[0038] Example 3. Preparation of Insect Repellent Mosquito Net Cloth.

[0039] Material Polypropylene mosquito net cloth, cloth weight 50g / m 2 , the target amount of deltamethrin is 140mg / m 2 . The pad dyeing method is adopted, and the equipment is a dyeing machine with a pad car (setting machine or resin finishing machine can be used). Two dipping and two rolling, the excess rolling rate is 65%, the heat treatment temperature is 120°C, and the time is 50s.

[0040] Liquid composition:

[0041] 10% Deltamethrin EC 5.0L

[0042] Acetic acid 1.0L

[0043] Add water to 100L

Abstract

This invention relates to the insect protected textile making method, the character is that it uses dip-dyed or roll-dyed to dye the Pyrethrum Ester onto the synthetic fiber textile or yarn, wherein the synthetic fiber includes the composite silk, single silk, stable fiber textile and natural fiber blended or interlaced textile of the polyester, polyamide, polyurethane, polypropene, polyethene, polyacrylonitrile, polyvinyl chloride, the yarn is the related composite silk, single silk, stable fiber textile and natural fiber blended or interlaced yarn; the Pyrethrum Ester is hydrophobic, its molecular weight is less than 700, the decompose temperate is higher than that is dip-dyed or roll-dyed, and it has at least one group of the -OH,-CN, -NH2,-NHR,-NR2,-NHCOR,-I,-CI,-Br,-NO2,-SONH2. The advantage of this invention is that the production flow is short, the operation is simple; and the dosage is controlled.

Description

technical field [0001] The invention relates to a method for preparing insect-proof textiles, in particular to a method for preparing insect-proof textiles by dyeing pyrethroids into synthetic fibers by using the dyeing method in textile industry production. Background technique [0002] Plant pyrethrums contain pyrethrins that can kill insects. Pyrethroids are analogs synthesized based on the structure of natural pyrethrins. They are more resistant to light and heat than natural pyrethrins. They can be used to prepare insect-resistant clothing, insect-resistant mosquito nets and agricultural insect-resistant insecticides used in daily life. net etc. [0003] At present, there are mainly two methods for producing insect-resistant fabrics. One is to combine pyrethroids in spinning solution to produce insect-proof fibers, and the other is to apply pyrethroids to the surface of fabrics by spraying, padding and other methods. [0004] According to the "2000 Hygienic Insecticide...
