Jual Cationic Softener

SOFTENERS have gained great importance in textile finishing; almost no piece of textile  leaves the production facilities without being treated with a softener. This softening treatment is to give the textiles the desired handle, make further processing easier and improve the handling properties. A nice, soft handle is often the decisive criterion for buying a textile and is therefore of most vital importance for marketing many textiles. 

A Softener's main purpose is to improve the aesthetic properties of textiles :

* It gives the fabric the desired handle; usually with imaginative descriptions such as soft, full, super soft, smooth, elastic, firm, dry, sludgy etc. 

* It positively influences the technological properties such as antistatic, hydrophilic properties, elasticity, sewability, abrasion resistance etc.

* It gives synthetic fibres a certain degree of natural feeling and improve the handling properties through secondary effects (antistatic, smoothness, moisture regulation etc.).

Application of textile softeners in practise :

Nort-ionic softeners 

Nonionic softeners do not carry any electrical charge and therefore do not possess any distinctive substantivity. Such products are applied by means of forced application. i.e. usually in padding mangle procedures. Non-ionic softeners can be combined universally, are stable to temperature and do not yellow. This is the reason why this product class is perfect for finishing optically brightened high-white articles. The soft handle of pure non-ionic products is only average.

Cationic softeners 

Cationic softeners show the best soft handle and are therefore used for household articles as well as for industrial articles. They have affinity to almost all fibres and are usually applied by the exhaust method. The only problem is the incompatibility with anionic auxiliaries (optical brighteners, dyeing auxiliaries) as well as their tendency to yellow in comparison with non-ionic products. Cationic softeners are mainly used for coloured textile sub strates . Product name : TEX-SOFT 90 PLM, ARQUAD 2HT-75

Amphoteric softeners 

Formulations based on amphoteric substances are usually for special products of certain applications. Amphoteric products give an average handle, are normally compatible with white and give the fabric a good hydrophilicity as well as excellent antistatic properties. Furthermore, amphoteric softeners are very sensitive to skin and are often biodegradable. The main application range is hygiene and terry-cloth articles. 

Anionic softeners 

Anionic softeners are being used less because of the somewhat poor handle and the low substantivity, but are still of importance for certain fields.

* as Sanforizing assistance thanks to their good re-wetting properties 

* as crease-preventing agents in dyeing processes (anionic products do not retard at all or only to a small extent) 

* for one-bath application with other anionic auxiliaries such as optical brighteners 

* as a raising assistant due to good smoothing and antistatic efficiency 

 * as a sizing fat 

Softener specialities 

Pseudo-cationic softeners 

Pseudo-cationic softeners can be classified between non-ionic (average handle) and cationic (yellowing) products. They take on a certain compromise, i.e. they can be used on white fabrics still having a good affinity and about the same soft handle as cationic products, providing that the drying temperature or condensation or thermofixation is not too high. 

Silicone micro emulsions 

Amino functional silicones have a big importance to textile softening companies. Their surface smoothening

and softening properties are above all other product groups. Micro and semi-micro emulsions can

be made with specially selected emulsifying recipes using aminofunctional silicones. They offer a number of advantages which ,are totally in keeping for modern textile finishing. The low particle size (microemulsions <O.Olp) semi micro emulsions ~0.1 p) allow for the additives to penetrate in to the fibre core and in this way allow for an excellent product distribution of the micro emulsion. Silicone micro emulsions give textiles an excellent inner softness and a distinctive surface smoothness without looking greasy. They improve the technological properties of the textile (e.g. abrasion resistance, creasing angle), support the elasticity and optimize the sewability. Micro emulsions have a good product stability and decrease the hazard of roller coverings . The use of fast-running machines/ devices with high shearing forces may cause problems when working with silicone micro emulsions (bath stability) unless specially optimized products for this application field were selected.

The softening capacity of silicones is based on the gliding behaviour on the fibre surface as well as in the fibre. Polydimethyl siloxanes attached to amino-functional groups allow for a better orientation and substantivity of the silicone on the substrate. This again leads to a better soft handle ("super soft)" and good washing permanency. Product Name : Micro Silicon MK 60
