TEXTILE AUXILIARIES

Whether textiles are for the home, car, camping or one’s own body, consumers desire products that are tailored to their needs. 

They must be flexible, durable, colour fast, wash-resistant, odourless and easy on the skin. Zschimmer & Schwarz offers auxiliaries for textile finishing that bestow exactly the properties you desire. Our product range includes a variety of indispensable all-rounders that ensure perfect textile dyeing, lubricating, finishing and more. In producing our auxiliaries, we remain focused on the needs of our customers while drawing on our extensive experience in the field. We are continuously working in our labs to optimise our products in order to keep up with fashion and market trends.

Yarn and fabric manufacture

From fibre to fabric
Chemical auxiliaries have made many things possible in the manufacture of yarns and fabrics, including the optimisation of yarn production, generation of specific effects such as hydrophilic properties or soft handle, improvements in the running characteristics on fabric generating machines and the careful handling of old textiles and fibre waste. Zschimmer & Schwarz offers products that are specially developed for yarn and fabric manufacture. These form the foundation of creating a textile surface structure from loose fibres.

SPINNING PRODUCTS

... 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.

TWISTING AND WEAVING (WEFT) LUBRICANTS

... 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.

WET 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.

WARP WAXING AGENTS

... 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.

LUBRICANTS FOR TEARING PROCESSES

... 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.

Pretreatment

Pretreatment makes all the difference.
A high-quality, finished textile product that meets all the customer’s needs can only be achieved with optimised pretreatment products and processes. Whether scouring, desizing or bleaching, it is absolutely essential to have the proper detergents, wetting and sequestering agents and suitable peroxide stabilisers.

SEQUESTERING AGENTS

... 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.

DETERGENTS AND WETTING AGENTS

... 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.

BLEACHING AGENTS

... 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.

ANTI-YELLOWING AGENTS

... 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.

Dyeing

The right products for beautiful colours that last!
It takes more than simply good dye to colour textiles. Our dyeing auxiliaries ensure that colours perfectly match our customers’ wishes and are protected against washing, sun, perspiration and chlorine for as long as possible.

 

DISPERSING AGENTS

... ensure even distribution of dye in the dye bath. This helps prevent precipitates and agglomeration of dye, which can cause uneven spotting.

SEQUESTERING AGENTS

... bind with hard water components and prevent precipitate formation.

PH REGULATING AGENTS, BUFFERING AGENTS, ALKALI AND ACID DONORS

... 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.

WETTING AGENTS, DEAERATORS, PADDING AUXILIARIES

... 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.

Levelling Agents, Dye Carriers

... 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.

Crease Preventing Agents

... 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.

Aftertreatment Agents

... improve the colour fastness and thus other textile characteristics such as wash, water, perspiration, chlorine and rub fastness.

Carpet Colouration

... is best done with the following auxiliaries: reserving, levelling and anti-frosting agents that are specially developed for carpet colouration.

Finishing

Small helpers with large effects.
These influence not only the colouring of textiles, but also their fire retardancy or water and oil repellency. Finishing products can have a positive influence in these areas. The application of finishing products can adjust antistatic properties – and thereby the resistance to soiling – according to the customer’s wishes, for example in the back coating of tufted carpets. In order to ensure a smooth finishing process, we offer a line of defoamers and thickeners. These provide the certainty that is especially necessary at the end of the value chain.

SOFTENERS

... 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.

WATER AND OIL REPELLENT AGENTS

... 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.

STIFFENING AND FILLING AGENTS

... 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.

HYDROPHILIC FINISH

... improve the physiological clothing parameters of synthetic fibres. Hydrophilic agents optimise the moisture absorption, transport and antistatic properties of sport and protective clothing.

FLAME RETARDANTS

... 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.

PRODUCTS FOR BACK COATING OF TUFTED CARPETS

... 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.

DEFOAMERS

... 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.

CROSSLINKING AGENTS

... 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.
