Problems solved by technology

[0007] The post-finishing method is simple and convenient to process, but most of the insect repellents are only attached to the surface of the fiber (some of them penetrate below the surface of the fiber), the fabric has poor washability, and the effect of insect repellent and mosquito repellent will continue to decrease as the number of washings increases.

Embodiment 2

[0101] Example 2 Preparation of long-acting insect repellent and mosquito repellent PP spunbonded nonwoven fabric

[0102] The insect-proof and mosquito-repellent masterbatch sample that embodiment 1 obtains is made into non-woven fabric through the following spun-bonding steps:

[0103] Feeding→melting→filtering→spinning→cooling→drawing→laying→consolidation→winding.

[0104] 1. Feeding:

[0105] Raw material: polypropylene, the addition amount is 95-99.9% (wt)

[0106] Insect-proof and mosquito-repellent master grain (prepared in embodiment 1) injection amount 0.1-5% (wt)

[0107] Equipment: suction system, injection machine

[0108] Process description: Through the suction system and injection machine, according to the above-mentioned metering ratio of feeding, the polypropylene raw material and the insect-repelling and mosquito-repelling masterbatch obtained in Example 1 are sent to the screw extruder for preliminary mixing.

Abstract

The invention discloses a long-acting insect prevention and mosquito repelling PP (Polypropylene) non-woven fabric, which is prepared by carrying out bended spinningon insect prevention and mosquito repelling master batch and PP; and according to the percentage by weight of the non-woven fabric, the adding amount of the PP is 95-99.9 percent by weight, and the injection quantity of the insect prevention and mosquito repelling master batch is 0.1-5 percent by weight. The formula of the insect prevention and mosquito repelling master batch comprises the following components in percentage by weight: 96.00-97.35 percent of PP, 0.25-0.35 percent of permethrin and 2.40-3.65 percent of low molecular weight polyethylene wax. The preparation method of the non-woven fabric comprises the following steps of mixing the insect prevention and mosquito repelling master batch by taking the PP as a raw material; and preparing the long-acting insect prevention and mosquito repelling PP non-woven fabric through a spunbonding process or a spunbonding-melt spinning-spunbonding process. The long-acting insect prevention and mosquito repelling PP non-woven fabric has insect prevention and mosquito repelling effects, and is non-toxic to the human body and non-irritating to the skin.

Description

technical field [0001] The invention belongs to the technical field of home textiles, and in particular relates to a long-acting insect-repelling and mosquito-repelling PP nonwoven fabric and a preparation method thereof. Background technique [0002] At present, in daily life and work, there are mainly two kinds of mature insect repellent methods: [0003] One method is to repel or kill mosquitoes in the environment, which uses a variety of repellents, mosquito killers and insecticides. But the effect of this method is not long-lasting, and the medicine released by the aerosol will cause certain harm to the human body, leading to respiratory problems, allergies and even poisoning. kinds of people and often used. [0004] Another method is to finish the textiles that are often in contact with the human body to make them have the effect of repelling insects and mosquitoes. At present, there are mainly the following methods for finishing: [0005] 1. Impregnation and paddi...
