“…Combined with the SEM image, it can be seen that when double-layer wool fabric is stacked in two layers, the wind resistance increases and it is not easy to be blown open by wind in the filtration process [ 21 ]. The increase of the gram weight and hair of the middle layer caused by the overlap of the two layers, which can better prevent the passage of small-particle-sized aerosol, thus increasing its filtration efficiency [ 22 ].…”

A systemic study on improving particulate pollutant filtration efficiency through the combination of conventional fabrics is presented with the objective of finding comfortable, yet effective airway mask materials and products. Fabrics, nonwovens, and their combinations made of cotton, silk, wool, and synthetic fibers are examined on their filtration efficiency for aerosol particles with diameters ranging from 0.225 μm to 3.750 μm under industry-standard testing conditions. It is found that composite fabrics can improve filtration efficiency more than just layers of the same fabric, and the filtration quality factor of some of the fabric combinations can exceed that of the standard melt-blown materials. In addition, fabric friction and charging between the combined layers also improve filtration efficiency substantially. With a broader understanding of the fabric characteristics, we may design mask products with reduced facial skin discomfort, better aesthetics, as well as the ability to alleviate the environmental impact of discarded protective masks in the extended period of controlling the transmission of pollutants and viruses, such as during the COVID-19 pandemic.

“…Serat kain yang bertekstur kasar memiliki kinerja lebih baik untuk menyaring partikel. 20 Penggunaan kain polyester non woven dengan multi layer akan meningkatkan tingkat penyaringan partikel serta permeabilitas udara pada kain multi layer akan berkurang. 21 Semakin banyak jumlah kain polyester non woven semakin tinggi pula tingkat persentase penurunan kadar debu total dan penambahan filter serabut kelapa mempengaruhi penurunan kadar debu.…”

Latar belakang: Proses produksi dry mortar menggunakan bahan baku pasir silika, semen, batu kapur dan bahan aditif menyebabkan terbentuknya debu di area kerja. Paparan debu yang berlebihan dapat mengakibatkan gangguan kesehatan. Hasil pengukuran debu total di area produksi mortar PT. YZ pada bulan Maret 2022 sebesar 12,48 mg/m3 tidak memenuhi persyaratan dengan Permenaker No. 15 Tahun 2018. Tujuan penelitian untuk mengetahui penurunan kadar debu total di area produksi mortar dan tingkat efektivitas media filter serabut kelapa dengan perbedaan jumlah kain polyester non woven.Metode: Metode penelitian menggunakan pendekatan True Eksperimental dengan desain penelitian pre-post test without control. Teknik pengambilan sampel dengan purposive sampling. Pengambilan sampel debu total menggunakan alat HVAS dengan metode gravimetri. Variasi jumlah kain pada penelitian ini yaitu 3 lapis, 4 lapis dan 5 lapis.Hasil: Hasil penelitian rata-rata persentase penurunan kadar debu total setelah perlakuan filter serabut kelapa dengan 3 lapis kain polyester non woven sebesar 22,26%, filter serabut kelapa dengan 4 lapis kain polyester non woven sebesar 28,19% dan 5 filter serabut kelapa dengan 5 lapis kain polyester non woven sebesar 39,91%.Simpulan: Filter serabut kelapa dan perbedaan jumlah kain polyester non woven efektif menurunkan debu total di area mortar PT. YZ. ABSTRACTTitle: The Effectiveness of Coconut Fiber and Variation Number Of Non-Woven Polyester Layers As Filter Media In Reduction of Total DustBackground: The dry mortar production process are using raw materials such a silica sand, cement, limestone and addictives causing dust in the work area. Excessive exposure to dust can result in health problem. The result of measuring the total dust content in the mortar production area of PT. YZ concreate in March 2022 amounting to 12,46 mg/m3 don’t meet the requirement by following Permenaker No. 5 of 2018. This study aims to determine the secrease in the total dust content in the mortar production area and the effectiveness of coconut fiber filter media with differences in number of filters for non woven polyester fabrics.Method: The research methode used a true experimental approach with pre-post test without control research desain and the sampling technique was purposive sampling. Total dust was collected using the HVAS with the gravimetric methode. variation number of filter fabrics in this study were 3 layers, 4 layers, and 5 layers of non woven polyester fabrics.Result: The result showed that the average percentage reduction in total dust content after coconut fiber filter treatment with 3 layers of non-woven polyester fabric was 22,26%, and coconut fiber filter with 4 layers of non-woven polyester fabric was 28,19% and coconut fiber filter with 5 layers of non woven polyester fabric by 39,91%.Conclusion: The coconut fiber filter and variation number of non woven polyester layer as filter were effective in reducing the total dust in the mortar area of PT. YZ.

“…They observed that the filtration efficiency of filter fabrics prepared from recycled polyester fiber was negligibly lower (2.1%-3.5%) than virgin polyester fiber due to the difference in polymer molecular weight and polydispersity index. They also suggested that recycled polyester filters can be effectively used for the dust filtration applications (Vinay Kumar et al, 2019a). Vinay Kumar et al in another work studied the tensile properties of recycled and virgin polyester nonwoven filter fabrics.…”

Purpose The most widely recycled plastic in the world is recycled polyethylene terephthalate (rPET). To minimize the environmental related issues associated with synthetic fibers, several researchers have explored the potential use of recycled polyester fibers in developing various technical textile products. This study aims to develop needle-punched nonwoven fabrics from recycled polyester fibers and investigate its suitability in oil spill cleanup process. Design/methodology/approach According to Box and Behnken factorial design, 15 different needle-punched nonwoven fabrics from recycled polyester fibers were prepared by changing the parameters, namely, needle punch density, needle penetration depth and fabric areal weight. Several featured parameters such as oil sorption, oil retention, oil sorption kinetics, wettability and reusability performance were systematically elucidated. Findings The maximum oil sorption of recycled nonwoven polyester is found to be 24.85 g/g and 20.58 g/g for crude oil and vegetable oil, respectively. The oil retention is about 93%–96% in case of crude oil, whereas 87%–91% in case of vegetable oil. Recycled polyester nonwoven possesses good hydrophobic–oleophilic properties with static contact angle of 138° against water, whereas 0° against crude oil and vegetable oil. The reusability test results indicate that recycled polyester nonwoven fabric can be used several times because of its reusability features. Originality/value There is no detailed study on the oil sorption features of needle-punched nonwoven fabrics developed from recycled polyester fibers. This study is expected to help in developing fabrics for oil spill cleanups.
