It is one of the most crucial processes done by a textile company on a fabric before it is shipped out of the mill. The process of dyeing enhances the appearance of the fabric by using colors and shades, and lends the fabric a fresh look that bleeds when washed.

Dyeing has a clear advantage over all the other processes as it can be carried out during any stage of textile production. Based on the type of garment produced, textiles are dyed as yarn, fabrics, or as garments. For this process, certain colored components called dyes are used, which are of two types, natural and synthetic. Some of the different methods of fabric dyeing are described below.

Direct Dyeing

In direct dyeing, the dye is applied to the fabric directly without the need of an affixing agent. Before the application, the dyestuff undergoes fermentation in case of natural dyes or chemical reduction for synthetic vat and sulfur dyes. It is mainly used for dyeing cotton and has water-soluble properties, making it suitable to apply directly on the fiber from an aqueous solution.

Yarn Dyeing

Yarn dyeing refers to a method in which the yarn is dyed before it is knitted or woven into fabrics. This method is mainly used for creating patterns, stripes, and checks using different colored yarns. The dyestuff enters deep into the yarn during the process of yarn dyeing. Some important forms of yarn dyeing are skein dyeing, package dyeing, space dyeing, and warp-beam dyeing.

Garment Dyeing

This method of dyeing involves the finished garments and includes clothes like T-shirts, sweaters, pantyhose, sweatshirts, and hosiery. It is incapable of use in tailored fabrics though, as the shrinkage variation can cause misshaping or distortion of the clothes. The process of garment dyeing is carried out by placing the garments together and dipping in a dye bath.

Stock Dyeing

In stock dyeing, the fibers or stock are dyed prior to spinning into yarn. In this method, the loose fibers are put in a dye bath that is heated to a specific temperature. Stock dyeing is mainly used for woolen fabrics. It is used to create color effects like heather used particularly in wool fibers.

Top Dyeing

Top dyeing is similar to stock dyeing, as it is dyed before the fiber is spun into yarn. The top is the fibers of the wool, from which the tiny fibers are removed, and involves selecting the long fibers used for spinning worsted yarn. This top is dyed with dyed tops of other colors to create color effects.

Enhanced Strength

Linen is known for its exceptional strength than all other natural fibers and thus has been in use since ancient times. This strong nature of the linen fabric ensures that it remains undamaged during wear and even when subjected to stress. Linen can endure any wear and tear during washing thus preserving the structure of the fabric intact. This enhanced strength and durable nature of linen ensure that it lasts longer than any other type of clothing, which in turn makes it a perfect addition to wardrobes. Besides, linen is also known for its natural insect repelling properties.

Breathable and Absorbent

Linen is a highly breathable material due to the hollow structure of its fibers. This ensures that adequate airflow is maintained inside the body, which plays a key role in regulating the body temperature. Compared to other materials, wearing linen clothing allows free circulation of air inside, which makes it ideal for use during the summer. Moreover, linen has a high absorbing capacity that can soak up moisture without getting wet. This makes linen perfect to wear during the summer, as it can effectively absorb the sweat produced from the body without becoming dampened.

Least Environmental Impact

Another major reason to go for linen clothing is that they have the least impact on the environment. Linen is obtained from flax plans, which needs no fertilizer for their growth. The production process of linen in knitting mills has minimal impact on the surroundings, as it takes only a little amount of water. Linen being a natural fiber is also biodegradable hence reducing the impact on the environment. Moreover, all the parts of the flax plant can be used for making linen and other purposes, which means that the wastage is minimal.

Most people are aware of the fact that silk fabric is made from silkworms, but how many of you know that spiders and mussels are also used to make silk? In fact, silk made from spiders is regarded as one of the best silk material ever discovered. There are different types of silk fabrics and their details are given below.

Pure Silk

This is the finest and purest of silks. Pure silk is made of silk fabric that is cleaned off the gum by boiling. Here, no additive is used, in order to balance the weight loss that occurred during the boiling and cleaning processes.

Mulberry Silk

As the name indicates, this silk fabric is made of the silkworm that lives on mulberry leaves, known as Bombyx. This is the commonly used silk fabric, and has many variants as well.

Wild Silk

This is the silk fabric which is made from silkworms that feed and live on oak leaves, instead of mulberry. Wild silk is also known as Tusser silk or Tussah silk, and offers a coarse texture to the clothes.

Silk Charmeuse

This is one of the perfect fabrics for designing your dresses, especially wedding gowns, as it has a lustrous texture and satin finish that is sure to steal the show. The beautiful drapes and supple nature of this soft medium silk will make it easier for you to adorn it. However, it is really hard to sew this material because of its slippery nature; hence you must be extra cautious while dealing with it.

Chiffon Silk

This is a wholesale knit fabric with a rough texture, which is perfect for making flowy clothes, especially gowns. The main advantage of choosing chiffon silk is that they come in a variety of colors and textures. However, this fabric is also hard to deal with while sewing because of its flimsy, thin, and slippery nature.

Dupioni Silk

Dupioni silk or silk dupion is a standard, weight reversible silk material with loose plain weaves and coarse texture. This fabric is made by weaving two colors of yarn from two cocoons in knitting mills, and hence offers a dull sheen and luster when viewed in a different light. The main advantage of Dupioni silk is that it will not wrinkle or crease easily. Furthermore, you can sew this material easily because of its robust nature.

Temperature-Regulating Clothing

You may have known about clothes that are capable of heating up or cooling down according to the wearer’s wish. This might soon become a reality according to what researchers from the University of California, Irvine (UCI) are claiming. They drew inspiration from nature in crafting a material that would possibly make this happen, unlike the wholesale cotton fabric. This material uses ideas from that of a squid’s body and is also said to be capable of stretching way beyond its normal state and then back to it a number of times without giving way to wear and tear.

The Science Behind it

The team looks up to the camouflage capabilities of the organism to craft their design. Squids have a type of skin which could rapidly change color. The scientists realized that they could use a similar principle in infrared in order to exercise control of transmittance and reflectance of heat.

The material was developed from the copper nanostructured film which happens to be embedded in a polymer matrix, which in turn has the same capabilities as a space blanket. The material can adjust temperatures so that the wearer feels comfortable wearing it. For instance, like the space blanket, it reflects your own body and maintains it in a warm state. As the environment gets hotter, its properties change and it releases heat, thereby helping you to get cool.

The material was initially tested on a guarded hot plate that resembled human skin in properties. According to the research team, when the material was stretched, it released heat and cooled the skin. They are currently working to incorporate better control into the material using an app to control the amount of heat dissipation.

This also stands posed to be a great discovery for the sports universe. They have already struck partnership with one of the athletic apparel companies. Its makers also believe that it can be used in offices as well. According to them, every person has a different temperature requirement and this material could provide the ideal remedy for that problem. In other words, this could lead to a potential 30-40 % savings on heating and air conditioning bills. The material could bring several drastic changes to the custom knit fabric industry as well.

The advent of the newly developed material could change the apparel industry drastically. There are several benefits to wearers if they use this material as it is capable of changing the temperature according to the desire.
