Definitions

  • compositions and methods for manufacturing textiles relate to compositions and methods for manufacturing textiles and more particularly, to compositions and methods which impart both UV absorbing and IR attenuating properties to textiles.
  • Dyeing is by far the most widely used means of applying color to textiles. Dyes, by definition, are soluble in the medium in which they are applied, and the medium is always water. The technical challenge for a dye-house is to control the forces that attract the dyes out of the water, bind them to fibrous substrate, and prevent their ready removed from the fibrous substrate during normal use.
  • the dyeing processes require three things: a fibrous substrate, dye dissolved in a transfer medium to form a dye-bath, and the necessary equipment to bring the fibrous substrate and dyebath into contact.
  • Any natural or synthetic material which occurs in, or can be rendered into, fibrous form has potential as a fibrous substrate.
  • the rayons and acetates are not, strictly speaking, man-made fibers since they are made from natural cellulose.
  • These eight fiber types can be used in two, three or four combinations to form a blend that satisfies a particular market or end-use requirement. Typically, the fiber types in a blend are increased in 5% increments.
  • the dyes must be soluble in the transfer medium and various chemical forces attract them out of the transfer medium and bind them to the fibrous substrate. Different dyes are attracted to different fibrous substrate by different forces. In fact, dyes are typically classified into the following seven categories based on the nature of the forces which bind them to the fibrous substrate: acid, which are used with wool, silk and nylons; basic, which are used with acrylics, silk and polyesters; disperse, which are used with polyesters, nylons, acrylics, and acetates; and direct, reactive, sulfur and vat, which are used with cellulose. When dying blends, the dyes for each application must be correctly chosen. It is rare for a dyebath to contain only a dye, a fibrous substrate, and a transfer medium. Usually there are a variety of chemical adjuvants used to insure the correct dyebath condition for the transfer of dye from the dyebath to the fibrous substrate, and to insure proper mechanical handling of the goods.
  • the dyeing process involves the dye solution and substrate being brought into intimate contact so that the transfer of dye from one phase to the other can take place as quickly, completely, umformly and economically as is practical.
  • various dyeing processes include jet dyeing, pad dyeing, and exhaustion dyeing.
  • UV radiation ultraviolet radiation
  • UV-A segment between 320 nm and 400 nm
  • UV-B segment between 290 nm and 320 nm
  • UV-C segment between 200 nm and 290 nm
  • the UV-B segment is considered to be the most dangerous causing sun burns, freckles, aged skin, tanning, and skin cancers.
  • the UV-C segment while possessing the greatest amount of energy, is considered less dangerous because it is mostly absorbed by the Earth's ozone layer. If the ozone layer continues to be reduced each year as many studies are indicating, protection against UV-C segment may be an increasing concern.
  • the first method is to cover the skin with clothing. Unfortunately, clothing acts as an insulation thereby reducing heat lost by the body. In addition, some clothing may actually absorbs infrared radiation, thereby making it a heat source.
  • the second method used to reduce UV exposure is to apply a sun-blocking chemical to the skin. Unfortunately, such chemicals are easily washed or removed from the skin and require repeat applications to be effective.
  • the amount of UV radiation protection offered by clothing depends of type of fabric, the tightness of weave, and the color of the fabric. Generally, summer or tropical-weightclothing has a "sun protective factor" (SPF) value between 5 and 15. Research has also shown that when clothing becomes wet, its SPF values are further reduced. Unfortunately, the most commonly used fabrics for clothing are made of cotton or cotton polyester blends which have relatively low SPF value. When manufacturing clothing which may become wet by weather conditions or perspiration, the wet SPF value of the fabric is a concern.
  • UV protectant chemicals for textiles have been developed by various companies.
  • One group of chemicals are benzotriazole derivatives.
  • One example of a triazine derivative is a chemical sold by Clarient Corporation of Charlotte, North Carolina, under the trademarks RAYOSAN C and RAYOSAN

  • the UV radiation absorbing chemical is a benzotriazole based chemical commonly applied only to polyesters and other man-made fabrics to absorb UV radiation.
  • benzotriazole based chemicals have not been applied to natural fiber fabrics to absorb radiation because of their chemical incompatibility in the usual and customary methods of dyeing and treating natural fibers.
  • Benzophenones have also been used to absorb UV radiation in polyesters however, their use in garment textiles has not been proven to be safe due to possible toxicity and biocompatibility issues.
  • Triazine based chemicals when applied to fabrics for UV absorption, increase the temperature of the fabric when exposed to solar radiation.
  • Benzotriazole based chemicals when applied to fabrics, do not.
  • HALS hindered amine light stabilizer
  • HALS are commonly used in the plastic industry to reduce the detrimental UV effects to plastics caused by sunlight.
