The document discusses nips, which are the pressure points between two rollers pressed together in textile processing. Uniform nips are important for producing uniform products. There are two broad classifications of nips - low squeeze and high squeeze - depending on the hardness of the rubber surface. Various methods are used to measure and ensure uniform nip pressure across the width, including static methods like carbon paper and electronic sensors, and dynamic methods like pickup percentage. Crownning, or providing a curved surface to the rollers, is used to compensate for inevitable bending and maintain a uniform nip line. Different roller designs and materials can be used to increase nip efficiency and squeeze more moisture from fabrics.

Finishing 1: Padding Mangles Stentering machine
The document discusses various types of machines used in textile processing, including mangles and stenters. It describes mangles as machines that squeeze moisture from fabrics using rollers. There are several types of mangles like ordinary, friction, and water mangles. Stenters are used to dry, heat set, and impart dimensional stability to fabrics. They grip fabric edges and carry the fabric through drying chambers using traveling chains. Hot air is typically used to dry fabrics in stenters. Key components include drying chambers, overfeed systems, and mahlo devices to straighten fabrics.
Pigment dyeing
Pigments are insoluble colorants that remain on the surface of fibers rather than penetrating inside. They are held in place mechanically by binders which are cured at high temperatures. For commercial use, pigments must have good heat resistance, dispersability, light/weather fastness, and be harmless and affordable. Binders are important as they bond pigment particles to fibers and form a clear film. The rubbing fastness of pigments depends on binder efficiency. Pigment dyeing involves padding dye paste onto fabric, drying, and curing at high heat to set the colors.
Mercerisation
Mercerization is a treatment of cotton yarn or fabric with a strong caustic soda solution that improves several qualities of the cotton. It increases luster and dye affinity, improves strength and stability, and results in smoother, rounder fibers. The process involves immersing cotton in a high concentration sodium hydroxide solution under tension control and then washing to neutralize the fabric. This summarizes the key points about mercerization from the provided document.
reactive Dyeing of cotton knitted fabrics
Exhaust dyeing is commonly used to dye cotton and cotton blend knitted fabrics. It involves dye migration from the dye liquor into the fabric batch using exhausting chemicals and circulation. Reactive and disperse dyes are most commonly used. Key parameters include temperature, speed, pressure, and cycle time. Proper preparation of dyes, salts, and chemicals is important to prevent issues. Checking points after dyeing ensure the required shade and pH are met before draining. An aftertreatment process includes neutralization, soaping, and fixing to improve wash fastness. Safety equipment and material safety data sheets are necessary in the dye house.

It works by saponification, emulsification, and solubilization using alkalis, surfactants, and sometimes solvents. The document provides details on scouring of different natural and synthetic fibers like cotton, silk, wool, polyester/cotton blends. It also lists typical recipes and procedures for scouring cotton and polyester/cotton blend goods.
Wool and silk scouring
This document discusses the scouring and bleaching processes for various natural and man-made fibers. It explains that wool requires a mild scouring process due to its sensitivity to alkali. Scouring of wool uses sodium carbonate or ammonium carbonate at below boiling temperatures. Bleaching can be done with reducing agents like sodium bisulfite or hydrogen peroxide, which produces a permanent whiteness. For silk, degumming using hot soap solution is required to remove the sericin gum. Hydrogen peroxide bleaching is preferred for silk. Man-made fibers require milder scouring, and polyester rarely needs bleaching, while nylon and acrylic can be bleached using sodium chlor

Spunlace (hydroentanglement)
Spunlacing, also known as hydroentanglement, is a process for bonding nonwoven fabrics using high-pressure water jets. Precursor webs made of fibers like cellulose are passed through multiple rows of water jets that entangle the fibers. This produces a bonded nonwoven fabric with properties like softness and absorbency. Key aspects of the process include forming the precursor web, passing it through water entanglement units with fine jet nozzles, and drying the saturated fabric. The process produces fabrics widely used in applications such as wipes, towels, and medical and protective clothing due to its strength and lack of binders.

Discussion on gas singeing machine in textile industries
1. Gas singeing is a process where fabric passes over a burning gas flame, allowing protruding fibers to burn off without damaging the main body of fibers.
2. The main components of a gas singeing machine are a coal/gas/petrol burner, brush, guide roller, squeezing roller, and trolley.
3. Key parameters of gas singeing include flame intensity, fabric speed, singeing position, distance between flame and fabric, and flame width, which must be optimized to completely burn off fibers without over-singeing the fabric.
Weft knitting machine & parameters of weft knitted fabric
Knitting is the interloping of yarn which is interlocking in various ways to form fabric. Knitting is the process of manufacturing fabric by transforming continuous strands of yarn into a series of interlocking loops, each row of such loops hanging from the one immediately preceding it. The basic element of knit fabric structure is the loop intermeshed with the loop adjacent to it on both sides and above and below it.
Wool finishing
Milling, crabbing, decatising, and carbonizing are finishing processes for wool, polyester, and nylon fabrics. Milling uses moisture, heat, and pressure to full and densify wool fabrics. Crabbing sets wool fabrics through tension and heat treatment to reduce distortions. Decatising sets wool fabrics by compressing them with steam between wool felt. Carbonizing converts polyester/cotton blends to 100% polyester by dissolving the cotton with sulfuric acid. Each process aims to stabilize fibers and set the fabric structure.
Mercirization
Mercerization is a process that treats cotton fabrics with a cold sodium hydroxide solution. This treatment causes the cotton fibers to swell and gives the fabric an increased luster and strength. John Mercer discovered the process in 1844, though it did not become popular until H.A. Lowe improved it in 1890 by preventing shrinkage during treatment. The modern process involves bathing cotton thread in sodium hydroxide then neutralizing it with an acid. This increases the thread's luster, strength, dye affinity, and mildew resistance. Mercerization results in fiber swelling and morphology changes that allow for more dye absorption and a brighter colored fabric with better color retention after washing.
Dyeing parameters
Special Instruction:
Fabric shrinkage must keep within ±5%
Color fastness should be 4-5 range
Pilling range 3 to 5
pH range 5.5 to 7

Raising Finishing
Raising is a mechanical process that uses revolving cylinders covered with metal points or abrasives to stand up the surface fibers of a fabric, creating a lofty texture. It is done on wet wool or dry cotton fabrics. Raising is used to create effects such as pile, fleece, peach skin, and a warmer, softer hand. There are two main types of raising machines - teasel raising machines and card wire raising machines. The two primary types of raising are napping, which uses metal wires to dig out fibers and create higher pile, and sueding, which uses abrasives like sandpaper for a lower, suede-like pile typically on silk fabrics.
Compactor
The document provides information about a compactor machine used to control fabric shrinkage. It summarizes the machine's functions, operating parameters, and components. Key points include:
1. The compactor machine compacts fabric in the lengthwise direction and provides overfeed to control shrinkage during processing with steam.
2. It lists the machine's functions such as improving hand feel, reducing thickness, and controlling shrinkage.
3. It describes the machine components and operating parameters like temperature, speed, and overfeed percentage for different fabric types.
4. Diagrams show the mechanism and fabric path through a blanket and tube compactor machine.
Air jet Loom
This document discusses jet weaving processes. In jet weaving, a fluid such as air or water is used to insert the weft yarn through the shed. For air jet weaving, compressed air is accelerated through a nozzle to provide the force to insert the weft. For water jet weaving, water is pressurized using pumps. Key factors that influence the tractive force on the weft include the velocity and viscosity of the fluid, the roughness of the weft yarn, and temperature. Modern jet looms can operate at high speeds up to 1500 picks per minute for water jet and even higher for air jet looms.
Knit Dyeing Machines
1. The winch dyeing machine dyes fabrics like wool and silk through a process where fabric ropes are circulated through a dye bath and around a winch or reels.
2. It has a front compartment where dyestuffs and auxiliaries are added to the main dyeing chamber gradually.
3. The fabric ropes are immersed in the dye bath and circulated through the dye bath and around the winch, with the dyestuffs being dosed manually or automatically.
Dryer Machine For Knit Fabrics
The document provides information about a drying machine used in textile processing. It contains details such as the machine having 2 chambers, 8 blowers, and 2 conveyors. It then explains that the machine removes residual water from fabric by applying heat through burner nozzles while continuously measuring humidity. The document further discusses parameters for operating the machine like temperature, speed, and overfeeding percentage which depend on factors like fabric type and weight. It also lists components of the machine and steps for cleaning and maintenance.
Rapier loom
The document discusses the rapier loom, a type of shuttleless weaving loom. A rapier loom uses finger-like carriers called rapiers to pull the weft yarn across the loom between the warp yarns. There are two main types - single rigid rapier looms, which use one long rapier across the full width, and double rigid rapier looms, which use two rapiers entering from opposite sides to transfer the weft yarn. Rapier looms can operate at high speeds up to 1300 meters of weft per minute. They are flexible and can weave a wide range of fabrics from light to heavy weights.
Slasher sizing machine
The document discusses the different zones and processes involved in a slasher sizing machine. The machine has three zones: a creel and size box zone where yarn passes through a size box, a drying zone where the sized yarn dries, and a front zone where the dried sheet is split. In the drying zone, one of three methods can be used: conduction with heated cylinders, convection with hot air, or radiation with electromagnetic waves. Conduction is the most common method used.
Chemical Proessing Finishing
Mechanical finishing of cotton. Stiff, soft, wrinkle resistant, water repellent, flame retardant and enzyme (bio-polishing) finishing of cotton; Milling, decatizing and shrink resistant finishing of wool; Antistatic and soil release finishing; Heat setting of synthetic fabrics; Minimum application techniques; Pollution control and treatment of effluents.
Garments washing
Garment washing is a process used to modify the appearance, comfort, and fashion of garments. There are various types of washes that produce different effects on fabrics, such as vintage, cloud, and acid washes. The type of wash depends on the product - for example, denim requires heavy enzyme washes while knit tees may only need a light softener wash. Common garment washing steps include a desizing process, washing with chemicals like detergent and enzymes, rinsing, drying, and quality checking. Washing introduces effects like fading and increases garment softness and comfort for customers.
4.1.04 polyester dyeing
1. The document discusses dyeing polyester fabric with disperse dyes and different dyeing methods, including using a carrier or high temperature dyeing.
2. It explains that a carrier helps the disperse dye penetrate polyester fibers better than normal dyeing, while high temperature dyeing at 130C can achieve deep shades without a carrier.
3. The experiments compare dyeing polyester with a carrier versus high temperature dyeing, and how being heat set first affects dye uptake, finding that heat setting before dyeing reduces uptake while carriers or high heat increase it.
Calendering
Calendering is a process that compresses fabric by passing it through rollers under controlled temperature and pressure. It is done to make fabric smoother and more lustrous after dyeing by reducing crimping and waviness. There are several types of calendering machines that use different roller materials and configurations to impart qualities like opacity, air permeability, thickness, and various degrees of luster. Calendering is commonly used to upgrade fabric hand feel and appearance for textiles.
Dyeing of cotton with vat dyes
This document summarizes the key properties and processes involved in dyeing cotton with vat dyes. Vat dyes are insoluble in water but can be converted to a water-soluble form through a process called vatting, which involves reducing the dye and forming a salt. The water-soluble form dyes cotton fibers, and is then re-oxidized inside the fibers. The dyeing process involves steps of reduction, dyeing, oxidation, and soaping to achieve bright shades and fastness properties.

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.
