... make it easier to turn fibres into yarn or nonwoven materials. Different types of fibres, new mixtures of materials and special manufacturing technologies require textile auxiliaries that can meet a wide range of requirements. These auxiliaries support production and are essential to numerous processes; for example, producing special or fancy yarns, processing cotton with honeydew deposits, big bag production or problems with electrostatic charge in all stages of production.
... are essential for modern, effective textile production. High-performance twisting machines subject sensitive synthetic materials to high stresses. Lubricants protect the yarn fibres from getting damaged, enable increased machine speeds and minimise cleaning efforts thanks to their ability to trap dust. These products are simultaneously used as warp oils or weft lubricants.
... enable the manufacture of coloured yarns. Dyed yarns are much easier to process if the natural lubricants (on cotton, for example) or primary finishes (on polyester or viscose, for example) lost in the dyeing process are replaced with effective wet lubricants. Depending on the use of the yarn, effects such as hydrophilic or hydrophobic properties or soft handle can be produced.
... improve how the warp yarn runs on the weaving machine. Warp waxing agents are reliable products for increasing production speeds for warp yarns that do not require classic smoothing. They reduce the incidence of breaks, prevent the use of clamps and thus increase the efficiency of the weaving mill.
... enable more careful processing of fibre waste. Recycling old textiles and fibre waste from the textile industry can be made much easier with special lubricants. Combining these with certain spinning auxiliaries (antistatic agents, for example) or softeners can produce additional effects.
... work by complexing with or removing disruptive alkaline earth ions and water hardeners. Sequestering agents have a diverse set of tasks. They can complex with disruptive Ca, Mg, Fe and Mn ions, among others. Furthermore, they are able to reduce water hardness, disperse dyes or soil particles, stabilise hydrogen peroxide bleaching, prevent silica deposition and improve the cleaning power of detergents.
... are essential for cleaning all types of textiles. Detergents and wetting agents can quickly wet textiles, reliably remove oily contaminants or dirt, support wool milling or emulsify natural oils, waxes or silicone oils depending on the requirements. Special products take environmental aspects into account (washing with microparticles, for example) or are suitable for medical textile use.
... perform special functions during the bleaching of cotton or viscose with hydrogen peroxide. Classic bleaching agents stabilise the peroxide bleach, meaning they control the bleaching process to minimise the damage to fibres. Bleaching agents can also be activators, enabling a high degree of whiteness to be achieved starting at a bleaching temperature of 75 °C.
... protect textiles from thermal and storage yellowing. Thermal anti-yellowing agents not only reduce the tendency for PA or PA/EL goods to yellow during the heat-setting and moulding processes, they also lower the chance of CO/EL goods yellowing during heat-setting. Storage anti-yellowing agents reduce phenolic yellowing of PA and PA/L goods as well as PES/EL products and other blends. Depending on the application, there are special products that give goods a neutral pH value or help prevent unwanted brownish yellow spots caused by certain finishing processes.
... ensure even distribution of dye in the dye bath. This helps prevent precipitates and agglomeration of dye, which can cause uneven spotting.
... bind with hard water components and prevent precipitate formation.
... ensure necessary dyeing pH values are achieved. Acid donors slowly lower the pH value until the minimal pH value is reached. Acid and alkali buffers set the necessary pH value and keep it stable.
... are additives that ensure good wetting, deaeration and defoaming and prevent undesired dye migration during continuous processing. Good penetration is important for evenly dyeing the entire fibre. Deaerators combine wetting and defoaming properties for low-foaming dye baths and thus support reliable dyeing processes.
... reduce and even out the dye strike rate for level dyeing. Levelling agents have high levels of affinity with dyes or fibres according to their use and prevent uneven dyeing or striping.
... optimise sliding properties, reduce mechanical resistance and minimise the formation of creases during dyeing. The various crease-preventing agents are adjusted for the respective fibres.
... improve the colour fastness and thus other textile characteristics such as wash, water, perspiration, chlorine and rub fastness.
... is best done with the following auxiliaries: reserving, levelling and anti-frosting agents that are specially developed for carpet colouration.
... are essential for a comfortable handle and improving the physical properties of woven and knitted textiles. Various finishing processes can negatively impact the handle and tear resistance of products. Fatty acid condensate softeners based on silicone or polyethylene produce elegant, appealing and high-quality goods as well as improved sewability and durability.
... are indispensable in the field of technical textiles. Products based on modern C6 chemistry fulfil the highest standards of water and oil repellency. In the field of fluorine-free finishing, Zschimmer & Schwarz offers a comprehensive selection of paraffin- or silicone-based auxiliaries.
... enable a large selection of handle qualities. In the areas of finishing and coating, they ensure anything from a very soft to extremely hard handle and have positive effects on a textile’s mechanical properties.
... improve the physiological clothing parameters of synthetic fibres. Hydrophilic agents optimise the moisture absorption, transport and antistatic properties of sport and protective clothing.
... protect the textile from flames. Textiles used for technical purposes – protective and home textiles, for example – must comply with various flame protection standards. Special agents offer these particular textiles the protection they require.
... promote the dissipation of electrical charges. These are added to carpet backings and allow easier dissipation of electrical charges which arise in the course of everyday use. Antistatic agents thus promote hassle-free and comfortable carpet usage.
... reduce foam formation in all aqueous processes. The formation of foam can seriously impact quality at every stage of textile finishing; for example, it can influence the evenness of dyeing or uniformity of coating. The use of defoamers can reliably suppress the formation of foam.
... are applied in conjunction with dispersions or fluorocarbon resin emulsions. Crosslinking agents enable better adhesion between the finish or coating and the substrate. In addition, the wash resistance of finishes and coatings with dispersions or fluorocarbon resin is significantly increased.
