Manufacturing chemical fibers and threads

Cellulose is a carbohydrate and the chief component in the walls of plants. Rayon is the oldest manufactured fiber, having been in production since the s in France, where it was originally developed as a cheap alternative to silk. Most rayon production begins with wood pulp, though any plant material with long molecular chains is suitable. There are several chemical and manufacturing techniques to make rayon, but the most common method is known as the viscose process. This substance gives its name to the manufacturing process, called the viscose process. The viscous fluid is allowed to age, breaking down the cellulose structures further to produce an even slurry, and is then filtered to remove impurities.

VIDEO ON THE TOPIC: How Its Made Carbon Fibre

Man-made fibre , fibre whose chemical composition , structure, and properties are significantly modified during the manufacturing process. Man-made fibres are spun and woven into a huge number of consumer and industrial products, including garments such as shirts, scarves, and hosiery; home furnishings such as upholstery, carpets, and drapes; and industrial parts such as tire cord, flame-proof linings, and drive belts.

The chemical compounds from which man-made fibres are produced are known as polymers , a class of compounds characterized by long, chainlike molecules of great size and molecular weight.

Many of the polymers that constitute man-made fibres are the same as or similar to compounds that make up plastics, rubbers, adhesives, and surface coatings.

Indeed, polymers such as regenerated cellulose, polycaprolactam, and polyethylene terephthalate , which have become familiar household materials under the trade names rayon, nylon , and Dacron trademark , respectively, are also made into numerous nonfibre products, ranging from cellophane envelope windows to clear plastic soft-drink bottles.

As fibres, these materials are prized for their strength, toughness, resistance to heat and mildew, and ability to hold a pressed form. Man-made fibres are to be distinguished from natural fibres such as silk, cotton, and wool.

Natural fibres also consist of polymers in this case, biologically produced compounds such as cellulose and protein , but they emerge from the textile manufacturing process in a relatively unaltered state. Some man-made fibres, too, are derived from naturally occurring polymers.

For instance, rayon and acetate , two of the first man-made fibres ever to be produced, are made of the same cellulose polymers that make up cotton, hemp, flax, and the structural fibres of wood. In the case of rayon and acetate, however, the cellulose is acquired in a radically altered state usually from wood-pulp operations and is further modified in order to be regenerated into practical cellulose-based fibres.

Rayon and acetate therefore belong to a group of man-made fibres known as regenerated fibres. Another group of man-made fibres and by far the larger group is the synthetic fibres. Synthetic fibres are made of polymers that do not occur naturally but instead are produced entirely in the chemical plant or laboratory, almost always from by-products of petroleum or natural gas. These polymers include nylon and polyethylene terephthalate, mentioned above, but they also include many other compounds such as the acrylics, the polyurethanes, and polypropylene.

Synthetic fibres can be mass-produced to almost any set of required properties. Millions of tons are produced every year. This article reviews the composition, structure, and properties of man-made fibres, both regenerated and synthetic, and then describes the ways in which they are spun, drawn, and textured into useful fibres.

For a full understanding of the material from which these fibres are made, it is recommended that the reader begin with the article industrial polymers, chemistry of.

Linen is a flax-based textile that is predominantly used for homeware applications. While linen is similar to cotton, it is made from fibers derived from the stems of the flax plant instead of the bolls that grow around cotton seeds. Garments made of linen are desirable in hot and humid climates. Unlike cotton, which tends to retain moisture for a significant period of time, linen dries quickly, which helps reduce heat retention in overly warm conditions. Manufacturing linen, however, is much more time and resource-intensive than making cotton, which has led to a steady reduction in popularity of this fabric that began with the invention of the cotton gin.

Textile Manufacturing Process

Contact by email. View data sheet information including technical data for material, temperature resistance, tenacity and ambient temperature and more. Filter bags, cartridges, and other sewn filter media are exposed to extreme temperatures chemicals, abrasives, and, occasionally, moist environments, for extended periods. These conditions degrade the filter media and thread, and the thread often gives out first. In some cases the thread is not appropriate for the application, or it simply wears out from chemical, temperature, or abrasive attack before the filter media. This is vitally important to the lifetime of the filter, significantly reducing the number of changeover cycles and achieving superior reliability throughout the entire usage period. High shrinkage inevitably results in shortened, non-dimensionally stable seams that may impair the function and performance of the filter.

Thread is a key component of many items that we use daily. From apparel that we wear, to the furniture we sit on, thread is all around us.

Anbumalar 1, R. This article will help anyone interested in starting a lingerie brand understand some critical foundations. As the name suggests, the manufacturing of these textiles does not require the steps of producing yarn and weaving it. For environmental safety, there are effluent treatment plants to treat the discharged water from processing house. Textile - Fibre to Fabric Processing P R Wadje, Non-member This paper is an attempt to provide all basic information related to textile Industry - in the field of manufacturing, purchasing, promoting, selling and so on. Reducing the cost of textile manufacturing, including home textiles and apparel, in the U. Fibers are spun into thread, which is then woven. Here we will explain each process in detail using some illustrations. Fabrics of various types - suiting, shirting, home textiles, and automotive furnishing - are manufactured here with world-class quality and production standards.

We generally refer to it as, "two or more yarns twisted together to form a single strand in a plied or corded construction". However, these days there are other 'Continuous Filament' constructions manufactured using technologies, like intermingling, texturising and air jet texturising which can produce a thread of a single ply construction. Coats produces many different threads and this will be explained within this technical bulletin. Most sewing threads today are based on synthetic materials, such as polyester or nylon, which have, to a large extent replaced the use of natural fibres like cotton and linen that used to be the material of choice. Handicraft threads are still predominantly made out of cotton, especially when the handicraft work is done by hand. However, if the handicraft effect is being created by a machine, as in the case of embroidery of logos , then synthetic threads are rapidly replacing cotton and rayon threads.

Dec 18, - The introduction and usage of some fibers and manufacturing process are known. Different fibers have different chemical and physical properties, With regard to hole size, small holes are difficult to thread and large holes.

Know Your Fibers: Cotton vs. Viscose Rayon

There are three basic steps required for fabric production. The first step in creating fabric is yarn production. Here, the raw materials that have been harvested and processed are transformed from raw fibers into yarn and threads. This is done by spinning the fibers. Spinning can be done by hand, but this process is quite tedious and time consuming.
