Fiber production in Senica has almost a century-old tradition, started in Under the brand name Slovak Silk, company originally produced viscose textile fiber, which was interrupted by the Second World War. After recovery for decades the company played a very important role in textile industry producing viscose, later polyester yarns. Modern spinning lines were installed in and new production program has been launched. Chemical fiber plant manufactures man-made fibers based on PTA, with utilization for different applications of technical fabrics.

Synthetic Fibers: The Manufacturing Process and Risks to Human and EnvironmentVIDEO ON THE TOPIC: OFS Fiber Manufacturing
Textile production takes place in several stages, all of which require different types of compounds to aid in cleaning, strengthening, improving aesthetic quality or preservation. The production of natural fibres, particularly plant fibres, requires the use of fertilisers, fungicides, pesticides and insecticides. These examples of cotton and wool production will elucidate further: Cotton, being the most widely cultivated source of plant fibre, utilises the largest amount of these chemicals.
Further, when cotton is machine-picked, it is sprayed prior to picking with a chemical defoliant, that assists the unnecessary leaves to fall to the ground. The same case applies to wool production.
It would take years to yield enough quantities of wool for textile production if animals are left to grow naturally. To promote faster growth and lower animal mortality, sheep rearers use requires organo-phosphorous pesticides to control pests. Additionally, once the sheep are sheared, their wool has to be scoured and washed using chemicals, which also contaminate water sources.
The use of chemicals is also experienced in production of synthetic fibres. The production of synthetic fibres also uses a large number of chemicals. Synthetic fibres are made from fossil oils, which in itself encourages environmental degradation.
To polymerise the petroleum extracts materials into fibres, different combinations of chemicals are used, including acids and salts.
After harvesting or manufacture, fibre is spun into yarn. During this stage, chemicals in the form of spinning oils and additives are used to add strength and consistency to the fibres as well as to minimise friction while spinning.

Curabitur pretium, ex vitae pellentesque tincidunt, enim diam fermentum nulla, eu porta augue leo eu odio. Phasellus volutpat arcu et magna luctus feugiat. Phasellus maximus purus arcu, nec tristique augue molestie ac. Fabrics are made from yarn and can either be knitted, woven or non-woven. Lubricants, and sizing chemicals are used in this stage to increase yarn strength and reduce friction.
For non-woven fabrics, chemical solvents and adhesives are added to bind the yarn together. Pretreatment is done on fibre, yarn and fabric to enable dyes and other chemicals to adhere better.
Fabrics are subjected to pre-treatment steps based on the type of fibre used. Some of the chemicals used include:. When dyeing a fabric, different fixation chemicals are used to make the dyes adhere and washing chemicals are also used during the washing process. When these dyes find are dumped into the environment as waste, it can take them up to 46 years to biodegrade.
When printing full-width fabrics, resins or binders are used for sticking printing pigments on to the fabric. Plastisol printing is more common for garment printing. The process uses a PVC-based adhesive that contains phthalates, which are known to cause hormonal defects in developing children. The printing machines emit gases such as volatile organic compounds VOCs and ammonia. It is estimated that the number of chemicals used from pre-treatment, to dyeing and finishing range between 20 to The effluent from these chemicals usually contains heavy metals, which are harmful when they contaminate water sources and soil.
Once the fabrics are finished, they are used to make end-user products such as clothing items. This process produces pollutants in the form of dust and formaldehyde fumes from the textiles being cut. Before being shipped to shops, the finished garments are first treated with biocides to protect against mould during transportation and while on shop shelves.
Roughly chemicals are used in textile production. Their impacts range from environmental to the health of workers and consumers. Fibre production The production of natural fibres, particularly plant fibres, requires the use of fertilisers, fungicides, pesticides and insecticides.
Fibre to Yarn After harvesting or manufacture, fibre is spun into yarn. Yarn to Fabric Fabrics are made from yarn and can either be knitted, woven or non-woven. Fabric pre-treatment process Pretreatment is done on fibre, yarn and fabric to enable dyes and other chemicals to adhere better. Some of the chemicals used include: Detergents and solvents for washing De-sizing chemicals to remove the sizing chemicals from the warps of a woven fabric e.
Bleaching makes it easier for the fabrics to absorb dyes easier. Mercerizing allows plant fibres to become stronger and accept dye easier. Acids for carbonizing fibres. Carbonizing removes impurities like pods and seeds from wool.
Scouring chemicals for removing fats, wax and grease from natural fibres. The table below shows some of the chemicals used in the scouring process. Finishing treatments It is estimated that the number of chemicals used from pre-treatment, to dyeing and finishing range between 20 to A few examples of chemicals used for finishing treatment include: Softening- polyurethanes and silicones Stiffening-starch resins or polyvinylalcohol Crease resistance- formaldehyde-based resins Water, oil and dirt repelant-fluorocarbons Anti-bacterial treatment-silver, triclosane 1 Garment production and shipping Once the fabrics are finished, they are used to make end-user products such as clothing items.

The fibres can be of countless origins, but can be grouped into four main categories. Natural fibres, with the exception of silk, have a relatively short fibre length, measured in centimetres. Silk and man-made fibres have on the other hand very long fibre lengths filaments ranging from hundreds of metres to kilometres long. Plant fibres consists of cellulosic material, normally derived from cotton, linen, hemp or bamboo, but more or less any plant with extractable cellulose can be used. Cotton is by far the most commonly used plant fibre and the cultivation of cotton is enormously resource-intensive, with high inputs of water, pesticides, insecticides and fertilisers leaving a large toxic footprint where grown, if not cultivated organically or under specific sustainable conditions.SEE VIDEO BY TOPIC: Viscose fiber production line
A textile  is a flexible material consisting of a network of natural or artificial fibers yarn or thread. Yarn is produced by spinning raw fibres of wool , flax , cotton , hemp , or other materials to produce long strands. The related words " fabric "  and " cloth "  and "material" are often used in textile assembly trades such as tailoring and dressmaking as synonyms for textile. However, there are subtle differences in these terms in specialized usage. A textile is any material made of interlacing fibres, including carpeting and geotextiles. A fabric is a material made through weaving, knitting, spreading, crocheting, or bonding that may be used in production of further goods garments, etc. Cloth may be used synonymously with fabric but is often a piece of fabric that has been processed.

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.
The textile process
The innovative technology has every chance to revolutionize textile and forest industries. For example, the cultivation of cotton is highly water intensive and only about 30 percent of cotton is produced in the areas where water is naturally available in sufficient quantities. The rest of the plantations are using irritation, which significantly increases the erosion of land and impoverishes the aquifers. As a result we are losing land suitable for food production and having groundwater reserves diminishing in ever-increasing pace. The global textile and yarn industry is mainly leaning to oil-based products such as nylon and polyester yarns. The third major sector in textile industry is Man-Made-Cellulose MMC -fibres, such as viscose and modal fibres that are wood-based materials. Usually the manufacture of these fibres requires a number of environmentally hazardous chemicals. In addition the high costs of MMC fibre production limits the application possibilities. Today the recycling rate of textiles is globally about percents. However, the changing legislation sets pressure on raising the recycling rate and inventing more environmentally friendly materials that also are recyclable.
Fibers & Textiles
Textile manufacturing is a major industry. It is based on the conversion of fibre into yarn , yarn into fabric. These are then dyed or printed, fabricated into clothes. Different types of fibres are used to produce yarn. Cotton remains the most important natural fibre, so is treated in depth. There are many variable processes available at the spinning and fabric-forming stages coupled with the complexities of the finishing and colouration processes to the production of a wide range of products.
Polyester is a synthetic fiber derived from coal, air, water, and petroleum. Developed in a 20th-century laboratory, polyester fibers are formed from a chemical reaction between an acid and alcohol.
