DRAFTING IN SPINNING PROCESS Principle of yarn manufacturing pdf
Drafting in yarn manufacturing is the process of attenuating loose fibers called slivers by passing them through rollers. This straightens and makes the fibers more parallel. Drafting involves pulling fibers through rollers at different speeds to lengthen and thin them out. There are three types of drafts: mechanical draft from speed differences between rollers, actual/resultant draft accounting for slippage, and tension draft from fiber tension. Drafting arrangements, elements, and settings are important factors that influence yarn evenness and strength.

Singeing
Singeing is a process that burns off small fibers and fuzz from fabric surfaces to make them smoother. It helps prevent pilling, improves dyeing and appearance, and increases luster. There are three main types of singeing machines: plate, roller, and gas machines. Gas machines are most common and use burners to singe fabric as it passes through. Proper singeing requires controlling flame intensity, fabric speed, distance to flames, and other parameters to completely remove fibers without damaging the fabric. Issues like uneven singeing can result from moisture, flame or machine inconsistencies.
non woven
Non woven
Nonwoven fabrics are broadly defined as sheet or web structures made of fibers or filaments bonded or interlocked together by mechanical, thermal, chemical or solvent means. They are flat, porous sheets that are made directly from separate fibers or from molten plastic or plastic film. They are not made by weaving or knitting and do not require converting the fibers to yarn.
Disperse dyeing
This document discusses disperse dyes, which are water-insoluble dyes used to dye synthetic fibers like polyester, acetate, and nylon. Disperse dyes penetrate fibers through weak Vander Waals forces and have a neutral charge. They require dispersing agents and high temperatures to dye polyester fabrics. The dyeing process involves an exhaust method where the dye bath is heated to 130°C to swell the polyester fibers and allow dye penetration. Disperse dyes have good fastness properties and provide a wide range of colors but are not environmentally friendly. The thermosol process is also described for dyeing mixed fabrics using a padding and heat fixation stage.

Testing UTM -hardness-impact
Mechanical tests of metals can be classified as either destructive or non-destructive. Destructive tests include tensile tests, used on ductile materials to measure strength and elongation; compression tests, used on brittle materials to measure reduction in length; and shear tests, which apply a pure shear force. Hardness tests include Brinell, Vickers, and Rockwell tests, which measure the hardness of a material by pressing an indenter into a specimen. Impact tests like Izod and Charpy tests study a material's behavior under sudden load. Fatigue tests determine a material's ability to withstand repeated stresses. Creep tests apply a steady load to determine the stress at which a material will not break over infinite time

Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
