Introduction: Introduction to Fabric Manufacture and the Process of Weaving

In this article, we will take a look at the warp sizing process.

The weaving process is one of the most important processes in textile production. It is a complicated process and requires a lot of expertise to get it done right. The different parts of the process are warp sizing, warping, weaving, and taking up.

The weaving process is a complex process, and it can be confusing to understand all the steps of the process. With this guide, we will break down each step of the process so that you can better understand how weaving works.

The weaving process starts with yarns. Yarns are made up of two strands: one strand is called the warp and the other is called the weft. The warp is set up on a loom in order to create a pattern, while the weft is woven through it.

In order for there to be a pattern created by this method, there needs to be two sets of yarns: one set called “warp” and another set called “weft.”

What is warping section or department in a weaving mill.

The term “warp” derives from its first use as a verb meaning “to weave”. Warp threads are longitudinal threads that run parallel to each other and are stretched in one direction across a loom. A weaver who prepares the warp is called a warper; one who prepares it after it comes from the mill is sometimes called an overseer or dresser. Warping is a process of preparing the loom to weave. It is the process of winding yarn or thread onto a long, narrow, continuous piece of wood called a warp beam. The yarns are held taut and parallel to each other. Once the warp has been wound on the beam, it can be secured in place with ties or clips.

What is sizing in a weaving mill or fabric manufacturing

Sizing is a process conducted after the warping function. Here the yarn lapped on beam is coated with some material which increases in strength of yarn so that it may run smoothly during the next step of fabric manufacturing.

Weaving Section

Here starts the final stage of Raw Fabric manufacturing. The Machines used in this process are called looms. There are several types of looms being used to produce fabric. We will introduce you to some mainly used weaving machines or looms in this article.

  1. What is Auto Loom or how an Auto Loom works:

    The auto loom function was invented by Charles Weldon in 1814. It was an improvement on a previous invention called the flying shuttle, which required a person to move it back and forth manually. The machine consists of two sets of threads, one set for each warp, that are stretched over and through a series of heddles and then attached to a shuttle that moves back and forth across the width of the fabric. The shuttle is controlled by cams on a rotating shaft with different patterns for each type of weave.
  2. What is Shuttle Less Loom or how a Shuttle Less Loom works:

    A shuttle is a device that holds the weft yarn, which is threaded through the warp yarns. A shuttle less loom function is a type of loom that does not require a shuttle to carry weft yarn. The first loom was invented around 4000 BC and it consisted of two sticks with threads stretched between them. It was used for weaving cloth by hand. The process of weaving cloth on these looms was slow, tedious, and required much skill. The invention of the shuttle less loom function in 1738 significantly changed this process and made it much quicker and easier.
  3. What is Air Jet Loom or how an Air Jet Loom works:

    The air jet loom is a type of loom that is more advanced than the conventional loom. It is used for weaving fabrics that are usually made from synthetic fibers. The air jet loom functions by blowing compressed air through a nozzle to create loops of yarn on the surface of the fabric. This process is known as looping and it resembles sewing in many ways. It creates loops by pressing the needle against the fabric’s surface and then releasing it to pull up a loop of yarn before repeating this process.

    Air jet looms are used to weave fabric. They use air jets instead of typical brushes or rollers. Air jet looms are also faster than most other looms, allowing production times to be much shorter.
  4. What is Water Jet Loom or How a water Jet Loom works:

    The water jet loom is a type of loom that is used in the textile industry for weaving fabrics. It was invented by the Swedish engineer, Bengt A. Malmqvist in the 1950s and has been improved on since then. The water jet loom functions by using a high-pressure water jet to produce its weft yarns.

    The water jet loom is a unique tool in the world of weaving. It uses the power of high-pressure water to create an intricate and diverse range of designs. Fabric woven on an air jet loom is stronger, more flexible and has better textural properties than traditional weaving.
  5. What is Rapier Loom or How a Rapier Loom works:

    Rapier looms are a type of power loom and they can be used to weave products such as tablecloths, rugs, and clothing. An ideal laptop for craft weaving is the HP w19i rapier loom. It offers maneuverability, flexibility and a sturdy design to ensure optimal performance while weaving on the go. Power looms use a series of wires that power your material through the weaving process; shuttle looms utilize this same concept but use shuttles that slide across the fabric rather than a series of wires.

    Rapier loom is a special type of power loom, with a slanted blade. It was used to propel the shuttle through between two sets of heddles, or to make the textile threads stretch out over one row of wood batten and then onto another row of batten at the other end of the loom. The term “rapier-loom” (or “rapier”) acquired its name from these blades that were designed so that the threads would be caught, or perhaps not caught at all, by these lower blades and then propelled into the shedder called “heddle bar”.

    The rapier loom is a hand-woven textile that uses a shuttle to weave individual threads. The rapier loom is most commonly used in the making of rugs, but it can also be used to make decorative fabrics, wall coverings and area carpets

Major fabric faults in weaving fabric

The fabric industry is a very large and important part of the clothing industry. The production of fabric starts with the manufacturing of yarns. There are many different types of fabrics, but they all have one thing in common: they are woven from yarns. Fabrics can be made from natural or synthetic fibers, or a combination of both. They can also be woven or knitted. The type determines the type of fabric and quality of fiber used to make it and the weave it is made in. Fabrics can be used for many purposes, such as clothing, upholstery, drapery, bedding and other household items such as curtains and tablecloths.

Grey fabric is a type of fabric that is not dyed. This means that the natural white color is preserved in the fabric and it will have no color variation. The main difference between white and grey fabrics is that grey fabrics can be used for multiple purposes such as making clothes, curtains, and bed sheets. Fabric faults are the most common problem that a fabric can have. Fabric faults can occur as a result of many factors. Some of these factors include the quality of the fabric, how it was handled, and how it was dyed. Fabric faults are a major concern for any fashion designer. The fabric may not be perfect, but these faults can make the garment look shabby and cheap.

The main types of fabric faults are:
Miss Pick
Starting Mark
Floats
Cracks
Coarse Pick
Coarse End
Selvedge Defect
Lose End
Sizing Stain
Increase Density

What is Miss Pick in Fabric?

Miss pick: Miss pick refers to a defect in which one or more weft yarns were missed during weaving process. Selvedge defect: This defect occurs when there are missing weft yarns at one or both edge of cloth due to warp thread. or Miss picks happen when the yarn is not properly picked up by the loom and is then woven into the fabric in a way that leaves an open space in between two rows of weft yarns.

What is a Starting Mark in Fabric

A starting mark is when a weft thread starts from an incorrect position on the warp beam. or
Starting marks are when there is an indentation on one side of the fabric caused by a starting shuttle being used to start weaving at one end instead of both ends.

What are floats in Fabric?

Floats are sections of yarn that hang off the selvedge of a fabric, which are created when there’s not enough space on either side of the fabric to keep them in place during weaving.

What are Cracks in Fabric

Cracks are caused by a variety of issues, including too much tension during weaving or improper drying after being washed.

What is Coarse Pick in Fabric

coarse pick is a result of the machine that was used to weave or knit the fabric. It can cause threads to be picked up from other parts of the fabric and woven into it.

What is Coarse End in Fabric

A coarse end occurs when the yarn, which was woven into the fabric, has not been properly cut off from the loom. This can cause problems such as fraying or unraveling of threads on the edge of cloth.

What is Selvedge Defect in Fabric?

Selvedge defect is a result of poor-quality control during weaving or knitting process. It occurs when one side of a fabric is not trimmed properly and threads are left on one side.

What is Lose End in Fabric

Lose end is caused by machine malfunctioning during weaving or knitting process, which leaves some threads loose on one side of a cut piece.

What is sizing Stain in Fabric

A sizing stain is a type of fabric fault where the fabric is treated with a sizing agent before weaving. Either too much or too little sizing agent can cause it. The most common way to identify a sizing stain is by looking at the back of the fabric. If there are small, white spots on the back, then it is likely that there was too much sizing agent applied to the fabric and it will shrink more than other fabrics in the wash. If there are large, white spots on the back, then it is likely that there was not enough sizing agent applied to the fabric and it will not shrink as much as other fabrics in a washing machine.

What is Increase Density in Fabric

Increase Density. This problem indicates that fabric has more picks or ends at some certain piece of fabric than the required standards.
