What Are The Best Fabrics to Wear in Tropical Climates...

Daily life in tropical areas can be intolerable for visitors who are wearing less than ideal clothing. Fabrics for tropical climates have a number of properties which make them highly suitable to wear and use in regions which get warm and humid.

In addition to seeking out better fabric choices, it is best to try garments on for fit and comfort, as clothing that is tight or fits oddly can be maddening in hot weather. It may be easier to purchase tropics-friendly clothing locally, and it might be a good idea to check what local people are wearing.

Keeping Cool

High temperatures combined with high humidity can make life uncomfortable, especially for people not used to these conditions. Humans keep cool mainly by sweating: the evaporation of liquid takes heat away from the body. Sweat evaporates less quickly when humidity is high, and so has less of a cooling effect. For this reason, fabrics for tropical climates should maximize the flow of air through the clothing, allowing heat and moist air to escape. It also helps if clothing is loose fitting.

Fabric Choices

Some fabrics tend to trap heat by providing an insulating layer over the skin. Others tend to reflect heat back to the body and inhibit the outward flow of warm, moist air; this is often true of synthetic fibers, such as polyester. Another important factor is the ability of a material to absorb water.

Synthetic fibers tend to be water-repellent; they allow sweat to build up, reducing evaporation, and causing discomfort and irritation. Natural fibers are generally better at soaking up moisture from the skin and allowing it to evaporate from the outer surface.

As a general rule, the best fabrics for tropical climates are those made from natural materials such as cotton, linen and rayon. Strictly speaking, rayon is a semi-synthetic fiber, but it is made from natural raw materials and resembles natural fibers in its properties.

These materials tend to “breathe” more than synthetics such as polyester. Wool and silk are not good choices, as they tend to retain heat, and silk can lose some of its strength through exposure to strong sunlight and perspiration.

Cotton

Cotton is an excellent material for a tropical climate because it permits movement of air from the skin through the fabric, allowing heat to dissipate and reducing humidity. It also absorbs moisture well, keeping the skin dry and increasing evaporation. This tendency to soak up water could potentially also be a problem: it can become damp and stay damp for some time.

Anyone who has worn denim cotton jeans in wet weather will know that they absorb a lot of water and take a long time to dry out. These, however, are made of relatively coarse, thick material; cotton clothing for hot, humid parts of the world should be made of thinner, lighter fabric.

Another useful property of cotton is that it can be machine washed and dried. As sweat accumulates in a hot climate, the ability to wash clothing quickly and easily is a definite advantage. Cotton is also easily ironed and reasonably durable.

Linen

Like cotton, linen is cool and absorbent, and very comfortable to wear. It loses water quickly when it gets wet or damp, which is a useful feature in humid conditions. The material is relatively stain-resistant and can be machine-washed; however, it tends to become wrinkled and creased easily, especially when tumble-dried, and ironing it can be hard work. It is also susceptible to mildew, which can be a problem in areas with high humidity.

Rayon

This fabric is made from natural cellulose, which is subjected to various chemical treatments to create a fibrous material suitable for clothing. Like cotton and linen, it is cool and comfortable to wear: it does not trap body heat, and absorbs water easily, making it well suited to tropical conditions.

Normal rayon, however, has limited durability, and should be dry-cleaned rather than washed. Another form of this fabric, called high-wet modulus (HWM) rayon, is much stronger and can be machine-washed.

Other Things to Consider

Generally, light colored fabrics are better for a tropical climate, because they reflect light and heat. White, beige, and pastels are common choices, and they can be embroidered with thread to create colorful designs. Tropics-themed textiles do not have to be dull white or shockingly patterned; options are varied when it comes to decoration.

Clothing for tropical climates should also be loose and comfortable. Many cultures have traditions of flowing garments which allow air circulation close to the body. In addition to being cooling, this also helps to keep the body dry, preventing irritation, rashes and skin infections.

People who are overweight may also want to consider the use of a cream or powder on areas of the skin which are subject to chafing, to prevent painful sores at the end of a day of activity in hot, humid conditions. More...

Tshirt Printing Manchester - How a Tshirt is Made

T-shirts are durable, versatile garments with mass appeal that may be worn as outerwear or underwear. Since their creation in 1920, T-shirts have evolved into a two-billion dollar market. T-shirts are available in a variety of colors, patterns, and styles, such as the standard crew neck and V-neck, as well as tank tops and scoop necks. T-shirt sleeves may be short or long, capped, yoked, or raglan. Additional features include pockets and decorative trim.

T-shirts are also popular garments on which to display one's interests, tastes, and affiliations using customized screen prints or heat transfers. Printed shirts may feature political slogans, humor, art, sports, as well as famous people and places. T-shirts are also inexpensive promotional vehicles for products and special events.

T-shirts fit just about anyone in any size, from infants to seniors. Adult sizes are generally small, medium, large, and extra-large, while sizes for toddlers are detennined by month and weight. In addition, to compensate for the larger heads of infants relative to their bodies, shirts are specially designed with shoulder openings that may be fastened with buttons or snaps.

Raw Materials

The majority of T-shirts are made of 100% cotton, polyester, or a cotton/polyester blend. Environmentally conscious manufacturers may use organically grown cotton and natural dyes. Stretchable T-shirts are made of knit fabrics, especially jerseys, rib knits, and interlock rib knits, which consist of two ribbed fabrics that are joined together.

Jerseys are most frequently used since they are versatile, comfortable, and relatively inexpensive. They also are a popular material for applying screen prints and heat transfers. Some jerseys come in tubular form, simplifying the production process by reducing the number of seams. Rib knit fabrics are often used when a snugger fit is desired. Many higher quality T-shirts are made of durable interlock rib knit fabrics.

Neckbands add support to the garment and give the neckline of the T-shirt a more finished look. Neckbands are generally one-by-one inch rib knits, although heavier fabrics or higher quality T-shirts may require two-by-two rib knits. Neckband fabrics may be tubed rib knits of specific widths, or flat fabric that must be seamed. Additional T-shirt materials include tape or seam binding, made of a twill or another stiff fabric.

Binding reinforces the neckline and shoulder seams and by covering the seams, it protects them from ripping apart under tension. Alternatively, elastic may be used at the shoulder seams so they remain flexible.

Thread is of course an essential element in sewing any garment. Several types and colors of thread may be used to make a single T-shirt. Some manufacturers use white thread for seams on all their shirts, regardless of color, thus eliminating the extra labor involved in changing the thread.

Visible topstitching is done with a color of thread that blends with the fabric. Colorless, or monofilament, thread could be used for hems of any color fabric, again eliminating the need to change thread often, though monofilament thread may irritate the skin somewhat. Finally, optional decorative features may include trim, such as braiding,

contrasting cuffs, appliqués, and heat transfer or screen print designs.

 

The Manufacturing
Process

Making T-shirts is a fairly simple and largely automated process. Specially designed machines integrate cutting, assembling, and stitching for the most efficient operations. The most commonly used seams for T-shirts are narrow, superimposed seams, which are usually made by placing one piece of fabric onto another and lining up the seam edges. These seams are frequently stitched with an overedge stitch, which requires one needle thread from above and two looper threads from below. This particular seam and stitch combination results in a flexible finished seam.

Another type of seam that may be used for T-shirts are bound seams, in which a narrow piece of fabric is folded around a seam, as at the neckline. These seams may be stitched together using a lockstitch, chainstitch, or overedge stitch. Depending on the style of the T-shirt, the order in which the garment is assembled may vary slightly.

Tshirt Printing Manchester - Cotton

Cotton is a soft, fluffy staple fiber that grows in a boll, or protective capsule, around the seeds of cotton plants of the genus Gossypium. The fiber is almost pure cellulose. Under natural condition, the cotton balls will tend to increase the dispersion of the seeds.

The plant is a shrub native to tropical and subtropical regions around the world, including the Americas, Africa, and India. The greatest diversity of wild cotton species is found in Mexico, followed by Australia and Africa.^[1]Cotton was independently domesticated in the Old and New Worlds. The English name derives from the Arabic(al) qutn قُطْن, which began to be used circa 1400 AD.^[2] The Spanish word, "algodón", is likewise derived from the Arabic.

The fiber is most often spun into yarn or thread and used to make a soft, breathable textile. The use of cotton for fabric is known to date to prehistoric times; fragments of cotton fabric dated from 5000 BC have been excavated in Mexico and the Indus Valley Civilization (modern day Pakistan). Although cultivated since antiquity, it was the invention of the cotton gin that so lowered the cost of production that led to its widespread use, and it is the most widely used natural fiber cloth in clothing today.

Current estimates for world production are about 25 million tonnes annually, accounting for 2.5% of the world's arable land. China is the world's largest producer of cotton, but most of this is used domestically. The United States has been the largest exporter for many years.^[3]

There are four commercially-grown species of cotton, all domesticated in antiquity:

• Gossypium hirsutum – upland cotton, native to Central America, Mexico, the Caribbean and southern Florida, (90% of world production)
• Gossypium barbadense – known as extra-long staple cotton, native to tropical South America (8% of world production)
• Gossypium arboreum – tree cotton, native to India and Pakistan (less than 2%)
• Gossypium herbaceum – Levant cotton, native to southern Africa and the Arabian Peninsula (less than 2%)

The two New World cotton species account for the vast majority of modern cotton production, but the two Old World species were widely used before the 1900s. While cotton fibers occur naturally in colors of white, brown, pink and green, fears of contaminating the genetics of white cotton have led many cotton-growing locations to ban growing of colored cotton varieties which remain a specialty product.

History

Main article: History of cotton

Cotton plants as imagined and drawn byJohn Mandeville in the 14th century

Cotton was first cultivated in the Old World 7,000 years ago (5th millennium BC), by the inhabitants of Indus Valley civilization. Evidence of cotton cultivation has been found at the site of Mehrgarh, where early cotton threads have been preserved in copper beads.^[4] Cotton cultivation became more widespread during the Indus Valley Civilization, which covered a huge swath of the northwestern part of the South Asia, comprising today parts of eastern Pakistan and northwestern India.^[5] The Indus cotton industry was well developed and some methods used in cotton spinning and fabrication continued to be used until the modern industrialization of India.^[6] Between 2000 and 1000 BC cotton became widespread in much of India.^[7] For example, it has been found at the site ofHallus in Karnataka around 1000 BC. The use of cotton textiles had spread from India to the Mediterranean and beyond.^[8]

Cotton fabrics discovered in a cave near Tehuacán, Mexico have been dated to around 5800 BC, although it is difficult to know for certain due to fiber decay.^[9] Other sources date the domestication of cotton in Mexico to approximately 5000 to 3000 BC.^[10]

The Greeks and the Arabs were not familiar with cotton until the Wars of Alexander the Great, as his contemporary Megasthenes told Seleucus I Nicator of "there being trees on which wool grows" in "Indica".

According to the Columbia Encyclopedia:^[8]

Cotton has been spun, woven, and dyed since prehistoric times. It clothed the people of ancient India, Egypt, and China. Hundreds of years before the Christian era, cotton textiles were woven in India with matchless skill, and their use spread to the Mediterranean countries.

In Iran (Persia), the history of cotton dates back to the Achaemenid era (5th century BC); however, there are few sources about the planting of cotton in pre-Islamic Iran. The planting of cotton was common in Merv, Ray and Pars of Iran. In the poems of Persian poets, especially Ferdowsi's Shahname, there are references to cotton ("panbe" in Persian). Marco Polo (13th century) refers to the major products of Persia, including cotton. John Chardin, a French traveler of 17th century, who had visited the Safavid Persia, has approved the vast cotton farms of Persia.^[11]

During the Han dynasty, cotton was grown by non Chinese peoples in the southern Chinese province of Yunnan.^[12]

In Peru, cultivation of the indigenous cotton species Gossypium barbadense was the backbone of the development of coastal cultures, such as the Norte Chico, Moche and Nazca. Cotton was grown upriver, made into nets and traded with fishing villages along the coast for large supplies of fish. The Spanish who came to Mexico and Peru in the early 16th century found the people growing cotton and wearing clothing made of it.More

Tshirt Printers Manchester - Gossypium hirsutum (more cotton)

Gossypium hirsutum, known as upland cotton or Mexican cotton, is the most widely planted species of cottonin the United States, constituting some 95% of all cotton production; it is native to Central America ^[1] and possiblyMexico.^[2] Worldwide, the figure is about 90% of all production for this species.

Archeological evidence from the Tehuacan Valley in Mexico shows the cultivation of this species as long as 5,000 years ago. This is the earliest evidence of cotton cultivation in the Americas found thus far.

Gossypium hirsutum includes a number of varieties or cross-bred cultivars with varying fiber lengths and tolerances to a number of growing conditions. The longer length varieties are called "long staple upland" and the shorter length varieties are referred to as "short staple upland". The long staple varieties are the most widely cultivated in commercial production.More
