This paper provides an explanation of the application of corona discharge plasma in textile field specially for modification of surface properties and wet ability of nylon 100% fabric. In this ...research, we have found that the properties of wet ability of nylon 100% fabric with 70 / inch of weft density and 60/inch of warp density is influenced by corona discharged plasma analyzed by the contact angle of the fabric on capillarity phenomena under same test time for contact angle test. Artikel ini menjabarkan pemanfaatan aplikasi teknologi plasma pijar korona pada bidang tekstil dalam modifikasi sifat pembasahan pada permukaan kain nilon 100% ditinjau dari sifat fenomena kapilaritas. Hasil riset memperlihatkan bahwa dengan perlakuan plasma pada kain nilon 100% dengan tetal pakan dan lusi masing-masing 70 helai/inci dan 60 helai/inci didapatkan bahwa terdapat perubahan sifat hidrofilik (dapat lebih mudah menyerap) kain melalui perubahan sudut kontak pada fenomena kapilaritas untuk waktu uji sudut kontak yang sama.

The application of physics, in particular, the topic of differential equations is commonly used in mathematics, physics, engineering, and various other sciences to explain a phenomenon in a system, ...to produce a form of simulation and prediction of a fairly good mathematical equation is needed. This paper examines the use of MATLAB / Simulink to assist in modeling the solution of the differential equation problems by providing a case of mathematical modeling in the analysis of the COVID-19 plague in Indonesia in 2020 with the modification of the Bernoulli equation. In this study, it can be concluded that MATLAB / Simulink can be used to solve differential equation problems with Bernoulli's modification in the case of COVID-19 plague modeling quite accurately.

image and computational processing techniques on woven fabric.
Keywords: woven fabric, digital image processing.
Suatu model matematis viskoelastik untuk menentukan besar koefisien viskos serta koefisien elastik suatu benang tekstil telah dikaji pada penelitian ini. Suatu persamaan matematis benang tekstil viz. ...100% wool yang memiliki nomor benang 36 tex atau 36 (g/km) telah dirumuskan menggunakan mekanika klasik. Hasil studi memperlihatkan bahwa pemodelan ini dapat digunakan untuk menentukan sifat viskoelastik material berdasarkan sifat stress relaxation. A mathematic model to find viscous of yarn as well as yarn elastic properties has been studied in this research. A mathematics equation of yarn viz. 100% wool having 36 (in unit tex or g/km) of yarn count number has been formulated using classical mechanics. In this research, we have found that this model can be applied to determine the viscoelastic material of yarn based on the properties of yarn as stress relaxation.
