The world of textiles is a complex place to be. With hundreds of processes, terminologies, and jargon, a newbie could easily lose his way around. In this Ultimate guide to yarn dyed fabrics, we will take a dive into the world of yarn dyed fabrics. Buckle up!

What are yarn dyed fabrics?

Yan dyed fabrics are those fabrics that are made using pre-dyed yarns. It is an ancient method of weaving and textile manufacturing where spools of yarns are dyed before weaving the fabric. The only difference today is that all the processes involved are mechanized or automated for more efficiency.

Let quickly look at the differences between fabric and yarns for the newbies here.

Yarns are individual threads that make up the cloth. The result of a weaving process is the fabric.

“The lengthwise yarn in a fabric is called warp yarn and weft yarns are woven across the length.”

The designs imprinted on a yarn dyed fabric are the result of sophisticated engineering efforts. These are the cool unique characteristics of yarn dyed fabric. Most of the fabrics that have stripes, checks, plaids, gingham, dotted or cross patterns are yarn dyed fabrics.

The Dobby type weaving process, where tiny crosses, dots, or lines are woven into the fabric is also a common type of yarn dyed fabric.

Denim is a perfect example of yarn dyed fabrics. The same goes for jackets and raw-looking apparel.

How to easily identify yarn dyed fabrics?

• The front and back of the cloth do not match with each other.
• Fabrics have slightly raised textures woven into them.
• Yarn dyed fabrics look more artisanal and rustic.

What is the difference between yarn dyed and piece dyed fabric?

Dyeing can be done at any point of time in a manufacturing process. It can happen at yarn stage, fabric stage, or even apparel stage. Depending on the client's requirements, relevant dyeing processes are considered.

In the piece dyeing process, the cloth is dyed after the weaving process. This is the most common type of dyeing in the world. Some of the techniques used for piece dyeing are:

• Jet Dyeing
• Jig Dyeing
• Pad Dyeing
• Beam Dyeing

“A typical drawback of piece RCGT Insert dyeing is that tightly woven fabrics that are used as uniform or upholstery could lose its color quickly. This is because of poor penetration of dye during the dyeing process.”

What are the other common fabric dyeing processes?

As we discussed in the previous section, dyeing can be done at any stage in the production process. Let's look at some of the popular dyeing processes prevalent today.

1. Garment Dyeing

Garment dyeing is the process of dyeing finished garments. Typically done of t-shirts or pants. The process involves placing the garments in mesh or net bags and then immersing them in vats of dye. They are loosely packed for even coloring.

2. Warp Beam Dyeing

An economical way of dyeing quantities of yarn. An entire warp beam is wound onto a perforated cylinder and Tungsten Steel Inserts then dyed using a dyeing machine.

3. Direct Dyeing

The process of putting dye directly on textile without the use of an affixing agent.

4. Stock Dyeing

Stock dyeing is a yarn level dyeing process that is done before the yarns are spun. The loose materials are put into large vats that are heated for required results.

5. Package dyeing

A package is a term used to refer to a spool of yarn. Such packages are dyed using a machine. It is a less expensive method of dyeing. The drawback of this method is that the yarns lose their softness.

6. Skein Dyeing

Skein dyeing is the process of dyeing yarns that are loosely wound into a dye vat. Yarns for knitting are typically processed in this way.

7. Top Dyeing

Dyeing process prior to yarn being spun. This is a dyeing process popular for wool yarns. Here, the long and short yarns are separated and only the long ones are used.

Which season is best for yarn dyed fabrics?

Different seasons require apparel designed to adapt to its conditions. The summer season requires breathable and lightweight fabrics to bear the heat of it. Whereas winter seasons ask for thick multi-layered fashion.

Since yarn dyed fabrics are not season-oriented, they can be worn in any season be it suits the person wearing them.

On a lighter side, wear what you feel like. Don't stress over the season. Fashion should not follow a season but an occasion. (Debates are welcomed in the comments)

What are the uses of yarn dyed fabric?

Yarn dyed items are found in our everyday items like home decor, fashion garments, accessories, and so on.

Popular yarn dyed uses:

• Tablecloth
• Kurtis
• Curtains
• Fabrics
• Other upholsteries

Are yarn dyed fabrics expensive?

The most expensive yarn dyed materials sold today are items that are hand dyed. With machines making most of our clothes, man-made clothes or fabrics are rare and expensive.

In this article, we discussed how to natural dye clothes at home. Anyone can dye their materials at home with proper techniques.

Artisans around the globe dyes items by hand thus increasing their value tremendously.

How to select the right Diamond Cutting blade? When selecting a blade for a particular job, there are several things we should consider.

Firstly, what type and shape of saw blades will work the best? The circular blade handles so many tasks with ease so it gets the wide usage. It is also available in extremely slender forms. On the other hand, specialized diamond cutting tools work better for certain jobs. As an example we can say that while working with a gemstone requires smaller tools, so bonding diamonds to a thin wire is essential.

You also need to think carefully about the kind of bond you want for our diamond cutting tools. The bond refers to the powder metals that hold the diamond to the base, and the bond is either soft or hard. Though it might seem a bit counter-intuitive, we want a soft bond on the diamond cutting blades when we're grinding through very tough material. The softer bond falls away more quickly, allowing new diamond edges to make frequent contact with the material we're cutting. By creating contact with newer diamond surfaces that are sharp, the diamond saw blades make a better go of cutting up hard material.

You must also consider what size diamonds we need, what concentration of diamonds we need on the blade, and their toughness.

Regardless of what kind of work we're doing, consider whether you need to use water with our cutting wheels. Water reduces dust flying into the air during grinding. It also cools the diamond saw blades and helps give these blades longevity. So, usually, it'APMT Insert s advisable to use diamond cutting tools wet and not dry.

So when you order a cutting disc, make sure that you request the correct diameter, blank thickness, arbor hole, and slots. In addition, consider adding diamond plated ribs to your blade to reduce wear and help with side cutting. Also specify the kind of edge you want, either round or square, for your diamond cutting blades. Ask about any special requests you have about tolerance and the thickness of the cut.

Specialized diamond cutting blades are readily available for road saws, handsaws, in addition to ring saws. Others are intended for specific tasks for instance cutting metal pipes or cleaning mortar ahead of tuck aiming. There are also special cutting blades for fire fighting and police, made to be able to cut through numerous building materials in order to get turning inserts for aluminum access easily.

1.Processing characteristics of gray iron

Gray cast iron has the characteristics of brittleness and low tensile strength (cast iron structure can be regarded as iron-carbon alloy structure filled with graphite pores. The presence of flake graphite reduces the ductility and toughness of cast iron) and is a typical brittle material.

The graphite cavity structure of flake graphite in gray cast iron is easy to form cracks with sharp edges. During cutting, under the action of the cutting force of the tool, the crack develops along the direction of minimum resistance, resulting in chipping and fracture of the chip. Therefore, the gray cast iron forms breakable chipping chips during the cutting process. At the same time, the tool is in the intermittent cutting working state during the processing of the gray cast iron. When the graphite in the base body is cut, the tool is in the idle state, and the metal is cut. In the case of the base body, the cutting action of the tool occurs, and the tool continuously cuts into and cuts out, causing the high-frequency pulling and compressive stress cycles of the tool near the cutting edge. The alternating load causes the surface layer of the tool to fatigue and causes slight chipping at the cutting edge, reducing The cutting performance of the tool.

During the cutting process, the cut gray cast iron structure frequently breaks irregularly, causing an unstable change in the cutting force and a large impact on the cutting edge. When the gray cast iron is cut, typical chipping chips are generated. The deformation coefficient of the chip is small, and the contact length of the chip is extremely short, so that the cutting force and the cutting heat are concentrated in a small area of the cutting edge, and the tool has thermal shock wear.

The chipping debris and the falling carbide hard spots generated by the cutter when cutting gray cast iron often cause the surface of the workpiece and the back blade to grind, resulting in wear of the flank VB abrasive; the cutting temperature is obviously increased once the flank face is worn, The fine chipping and chipping easily enters the chipping interface. Under high temperature and high pressure, the iron element in the chip and the surface of the tool and the tool surface form an infinite replacement solid solution, resulting in diffusion wear, while the chip softens and adheres to the tool surface. The wear surface forms a uniform layer of adhesion resulting in bond wear. Once the edge of the cutting tool wears or chipping, the cutting force is sharply increased, the surface quality of the workpiece has been significantly reduced, and the edge is prone to breakage or collapse, which is easy to collapse;

2.The effect of main cutting angles

The 90 degrees of the main cutting angles will radially introduce the feed force into the thinner part of the workpiece material;

45 degrees of  main cutting angles will direct the force to the material supported by the wider base;

Gaps and burrs occur when the feed force exceeds the material strength. Brittle materials such as cast iron tend to have gaps, while more tough workpiece materials tend to have burrs. More tough workpiece materials often have burrs. It directs the feed force to the tougher part of the workpiece material. This reduces or eliminates the formation of workpiece nicks or burrs.

3.Effect of different cutting edge grooves

The use of a sharp grooved blade can effectively reduce the cutting force and reduce the occurrence of chipping. At this time, fz is limited by the average chip thickness of the blade. Try to choose a blade type with good strength but sharp edge (cutting light groove shape, large front angle, sharp but strong strength blade type (smaller blade width T), during roughing, if in working condition When it is not stable, when the large fz (more than 0.2) is used, the phenomenon of chipping will be aggravated, especially when the tool cuts in and cuts out the workpiece. After the blade wears more than 0.3, this phenomenon is also the same. Will increase.

4.The effect of different materials

Physical vapor deposition (PVD), coating applications are thinner and rod peeling inserts suitable for relatively sharp cutting edges. The coating increases lubricity and helps reduce the cutting forces generated between the tool and the workpiece, making the cutting relatively light. Especially for the edge collapse phenomenon during finishing, there will be a great improvement.

5.Other factors
In the current machining market, for the processing of cast iron materials, from the actual processing results, the tool life of ductile iron materials (mainly burrs) (below QT450) is better than that of gray iron (mainly workpiece chipping). Workpiece chipping and burrs lead to a large factor in tool change. In addition to the 45 degrees lead angle we often use, the sharp-groove type of blade is used, which is relatively small for each tooth. It also strengthens the clamping rigidity of the workpiece slot milling cutters itself (adding auxiliary support to weak parts), and can also change the position of the tool and so on.
