Bath Towel

Bath towels are woven pieces of fabric either cotton or cotton-polyester that are used to absorb moisture on the body after bathing. Bath towels are often sold in a set with face towels and wash cloths and are always the largest of the three towels.

Bath towels are generally woven with a loop or pile that is soft and absorbent and is thus used to wick the water away from the body. Special looms called dobby looms are used to make this cotton pile. Bath towels are generally of a single color but may be decorated with machine-sewn embroidery, woven in fancy jacquard patterns pre-determined computer program driven designs or even printed in stripes. Since towels are exposed to much water and are washed on hot-water wash settings more frequently than other textiles, printed towels may not retain their pattern very long.

Most towels have a two selvage edges or finished woven edges along the sides and are hemmed cut and sewn down at the top and bottom. Some toweling manufacturers produce the yarn used for the toweling, weave the towels, dye them, cut and sew hems, and ready them for distribution. Others purchase the yarn already spun from other wholesalers and only weave the toweling. Until the early nineteenth century, when the textile industry mechanized, bath toweling could be relatively expensive to purchase or time-consuming to create.

There is some question how important these sanitary linens were for the average person—after all, bathing was not nearly as universally popular years ago as it is today! Most nine-teenth century toweling that survives is, indeed, toweling probably used behind or on top of the washstand, the piece of furniture that held the wash basin and pitcher with water in the days before indoor plumbing.

Much of this toweling was hand-woven, plain-woven natural linen. Fancy ladies' magazines and mail order catalogs feature fancier jacquard-woven colored linen patterns particularly red and white but these were more likely to be hand and face cloths. It wasn't until the s that the more soft and absorbent terry cloth replaced the plain linen toweling. As the cotton industry mechanized in this country, toweling material could be purchased by the yard as well as in finished goods.

By the s, an American house-wife could go to the general store or order through the mail either woven, sewn, and hemmed Turkish toweling terry cloth or could purchase terry cloth by the 'y'ard, cut it to the appropriate bath towel size her family liked, and hem it herself.

A variety of toweling was available—diaper weaves, huck-abacks, "crash" toweling—primarily in cotton as linen was not commercially woven in this country in great quantity by the s.

Weaving factories began mass production of terry cloth towels by the end of the nine-teenth century and have been producing them in similar fashion ever since. Raw materials include cotton or cotton and polyester, depending on the composition of the towel in production. Some towel factories purchase the primary raw material, cotton, in lb kg bales and spin them with synthetics in order to get the type of yarn they need for production.

However, some factories purchase the yarn from a supplier. These yarn spools of cotton-polyester blend yarn is purchased in huge quantities in 7. A single spool of yarn unravels to 66, yd 60, m of thread. Yarn must be coated or sized in order for it to be woven more easily. One such industry coating contains PVA starch, urea, and wax. Bleaches are generally used to whiten a towel before dyeing it if it is to be dyed.

Again, these bleaches vary depending on the manufacturer, but may include as many as 10 ingredients some of them proprietary including hydrogen peroxide, a caustic defoamer, or if the towel is to remain white, an optical brightener to make the white look brighter.

Synthetic or chemical dyes, of complex composition, which make towels both colorfast and bright, may also be used. Most towels are not specially designed in complex patterns.

The vast majority is simple terry towels woven on dobby looms with loop piles, sewn edges at top and bottom. Sizes vary as do colors depending on the order. Increasingly, white or stock towels are sent to wholesalers or others to decorate with computer-driven embroidery or decorate with applique fabric or decoration. This occurs in a different location and is often done by another company. The filler yarn is programmed so that it is loosely laid into the woven fabric. When this loose filler is beaten or pressed into the fabric, the slack is pushed up becoming a little loop.

After being dyed, the towel is hemmed and cut into standardized sizes. Shuttles, which carry the filler threads, are truly shot across these large looms at top-speeds—these towel-making looms may have 18 shuttles fired across the warp from a firing cylinder.

One shuttle follows right behind the next. As soon as the one shuttle shoots across the warp threads, the shuttle drops down and is transported back to firing cylinder and is shot across again. A typical towel-weaving machine has shuttle insertions in a single minute—nearly six shuttles fired across each second. Thus, towels are woven very quickly on these large mechanized dobby looms. In one small towel-making factory, dozen bath towels can be made in one loom in a single week—and there are 50 looms in the factory.

Towels are rigorously checked for quality control throughout the production process. If yarn is purchased, it is randomly checked for weight and must be the standard established by the company lighter yarn spools indicate the yarn is thinner than desired and may not make as sturdy toweling. Bleach and dye vats are periodically checked for appropriate chemical constitution. During the weaving process, some companies pass the cloth over a lighted inspection table.

Here the weavers and quality inspectors monitor the towel for weaving imperfections. Slightly unevenly woven towels may be straightened out and touched up. But those that cannot may be labeled "seconds" or imperfect or completely rejected by the company. As in all aspects of the process, visual checks are a key to quality control—all involved in the process understand minimum standards and monitor the product at all times. Potentially harmful byproducts are often mixed in the water that is used to bleach, wash, and dye the towel fabric.

Particularly, the bleaching process includes ingredients peroxides and other caustics that cannot be discharged untreated into any water supply. Many toweling factories run their own water treatment plants to insure that the water the plant discharges meets minimum standards for pH, temperature, etc.

A review of the sustainable methods in imparting shrink resistance to wool fabrics

Skip navigation. Most textile and wool products must have a label listing the fiber content, the country of origin, and the identity of the manufacturer or another business responsible for marketing or handling the item. Federal labeling requirements for textile and wool products, enforced by the FTC, require that most of these products have a label listing the fiber content, country of origin and identity of the manufacturer or another business responsible for marketing or handling the item.

Wool fiber is a natural protein fiber, which is used for the manufacturing of apparels, and floorcoverings because of its excellent fire retardancy, stain-resistance, antistatic and odor control properties along with exceptional warmth and resilience. However, wool fiber has several serious demerits, such as garments made of wool fibers extensively shrink during their laundering. To overcome this problem, wool fibers, especially those are used in apparel, are frequently shrink-resist treated to make them machine-washable. A wide range of treatments including oxidative, enzymatic, radiation, polymeric coatings, sol-gel coatings, and plasma treatments have been investigated to make wool fiber shrink-resistant. In this review, the mechanisms of wool fiber shrinkage, the research carried out until recently to make wool fiber shrink-resistant, and the current status of the sustainable alternatives developed, have been compiled and presented. The various methods investigated have been critically discussed with their merits and demerits, shrink-resist performance, and their shrink-resistance mechanisms.
