Textile fabric may be defined as the flexible assembly of fibers or yarns, either natural or manmade. It may be produced by a number of techniques, the most common of which are weaving, knitting, bonding, felting or tufting. Conventional fabrics (woven, knitted) are produced in such a way that the fibers are first converted into yarn and subsequently this yarn is converted into fabric. The fabrics can also be produced directly from the fibers. Such fabrics are termed as nonwovens. Each of these methods is capable of producing a large number of fabric structures, depending upon the raw material, machinery and the process involved. These fabrics are used for a wide range of applications from clothing to the technical purposes.

2 Warp Preparation Steps

A summary of the process steps from yarn to the final product, here the warp yarn is subjected to a number of processes, termed as warp preparation before conversion into fabric, while weft yarn does not require any specific preparation. The warp preparatory process consists of the following operations: winding, warping, sizing and drawing-in.

Yarns produced in spinning are used as input of the warp preparation. Winding helps to prepare the yarn for a package which requires shape and size. Weft yarn is then provided to loom, while warp yarns are processed to give a sheet of yarns on warp beam by the process called warping. A coating of size material is applied to the yarn in the subsequent process to impart strength and make the yarn smooth. This warp sheet is then drawn in from the droppers, heald frames and the reed. The actual fabric forming process is carried out at the loom, where this warp sheet and weft are interlaced to give woven fabric.

This is only a brief introduction about it.

Whats the Difference? Gauze Pads vs. Gauze Sponges

Gauze is a type of thin medical fabric with a loose open weave used in wound care. Both gauze pads and gauze sponges are made of 100% cotton. They wick vertically to draw exudates out of wounds and are stronger than other types of dressings due to their longer fibers. Our gauze is offered in both sterile and non-sterile forms. For open wounds it is recommended to use sterile gauze only.

Gauze pads and gauze sponges are used in a number of different applications and are great for general cleaning, dressings, prepping, packing and debriding wounds. It can also be used as a temporary absorbent dressing over wounds. You would want to use gauze for cushioning or packing a wound, helping to heal the tissue from the inside out. The difference between these items are that gauze pads come with one per pack, while gauze sponges come with two or more per pack.

Absorbent

An absorbent material has small holes in it. When a liquid, such as water, comes into contact with a material with tiny holes in, such as paper or a sponge, the liquid is drawn into the tiny holes. It spreads out through the material using the holes. An absorbent material can even draw a liquid upwards. If you put a sponge or dishcloth on top of some water on a kitchen surface the water will go up into the absorbent material.
We use absorbent materials to soak up spills and for drying up. Kitchen towels (both cloth and paper) are absorbent. We use them for drying the washing up and for drying ourselves after a bath or a shower. Cotton wool is another absorbing material. It is used in bandages to absorb blood from a wound. A material called oasis is used to absorb water in a plant display, and pass it on to the plants.

Absorbent materials can be a problem. For example you do not want to be caught in a shower of rain when you are wearing absorbent materials. They will hold on to the water, making you feel wet and cold. Bricks absorb a little water. Those at the bottom of a wall absorb water from the ground. If this water moved up the wall and into the building it could cause damp walls. The water is stopped by placing a non-absorbent material between layers of bricks near the bottom of the wall. You may see this material as a black line in the cement low down in a wall. It is called a damp-proof course.

What Is Rayon? Here's What You Should Know

Rayon is one of the most versatile fabrics around, yet it remains somewhat of a mystery. That's partly because of its remarkable ability to shape-shift—not just literally, but also in terms of imitating other fabrics. Rayon has been known to take on the properties of silk, cotton, wool, and others, and can be used in nearly any type of clothing. This can make it challenging to pin down exactly what it is, how to launder it, and what type of weather it's best suited for. To help boost your familiarity with this ubiquitous fabric, keep reading to see everything you need to know about rayon.

What Is Rayon Made of?

In a nutshell, rayon is a fabric made from purified cellulose fibers, which are typically created from wood pulp. Though rayon is derived from natural materials, it requires certain chemicals, so it's considered to be a semi-synthetic fabric.

One of the most common types of rayon is viscose rayon, which has a lot in common with cotton. It's breathable, moisture-absorbent, and a popular choice for casual and athletic wear. It also shows up in dresses, blouses, and outerwear. Secondary types of rayon include modal rayon (typically made from beech trees) and lyocell (seen in everything from denim to dress shirts).

Laundering rayon takes a little extra consideration. Rayon is often blended with other fabrics (such as polyester and cotton), so washing instructions can vary significantly. While its texture and versatility make it an ideal choice for a range of apparel, rayon isn't a durable fabric, and standard machine washing can cause it to stretch, shrink, or bleed onto other articles of clothing. As a result, most experts recommend hand-washing rayon, but always be sure to check the care label instructions beforehand.

What is Air Jet Loom?

Air jet loom is one kinds of shuttle less loom. Normally, air jet loom uses a jet of air for propelling the filling yarn through the weaving shed. It requires uniform filling yarn. They are suitable use with medium weight yarns then very light and very heavy yarn. Air jet loom is one of the two types of fluid jet looms where another one is water jet loom.

Features of Air Jet Loom:Some key features of air jet loom have mentioned in the below:

1. In case of air jet loom, higher weft insertion performance occurred.

2. Less power consumption in air jet loom.

3. It needs multi-color weft insertion up to eight.

4. Air jet loom provides higher production than others.

5. Light and medium fabric has produced here.

6. Here fabric width is 190 cm.

Advantages of Air Jet Loom:Different advantages of air jet loom have pointed out in the following:

1. In case of air jet loom, noise level is lower than rapier loom and missile.

2. Normally, standard width of air jet loom is 190cm.

3. Weft insertion performance is too much here (normally 600pm).

4. It consumes very low power.

Disadvantages of Air Jet Loom:The main disadvantages f air jet loom are-

1. Broken pick or miss pick has occurred due to excess air pressure of main nozzle.

2. In case of air jet loom, pile up and buckle tip of yarn formed due to air resistance.

3. Double pick may occur in air jet loom.

4. Loom of weft yarn along weft direction formed due to variation of air pressure.
