Polyacrylates are an important class of polymers that are soft, tough and rubbery. Their glass transition temperature is below room temperature. They are known for their high transparency, good impact toughness and elasticity. They have fairly good heat resistance up to 450 K (176.85 C) under dry heat. They also have good weather ability and ozone resistance since they do not have double bonds in the backbone. Polyacrylate polymers are used as super absorbents in consumer products. Many synthetic resins are produced by polymerization of acrylic esters. Forming plastic materials of notable clarity and flexibility under certain methods, the polyacrylates are employed primarily in paints and other surface coatings, in adhesives, and textiles.

Polyethylene wax

Polyethylene wax is linear and crystalline. Due to its high crystalline nature, this material has unique features such as hardness at high temperatures and low solubility in a wide range of solvents. Polyethylene wax also features limited poly disparity and molecular weight. Consequently, the material is highly resistant to chemical attacks, has unmatched heat stability and is very flexible in formulating applications. Polyethylene wax can be either low-density polyethylene (LDPE) or high-density polyethylene (HDPE). The wax finds application in a wide range of industries because of its desirable physical and chemical properties. As the material can have a broad range of melt points, densities, and other properties, it is understandable why it is used so extensively. In the textile industry, this material probably finds the most intensive application. Emulsions containing polyethylene wax offer stable softening. While they resist to acids and other chemicals, these emulsions are friendly to the fabric with no yellowing of fabrics, no color change, and no chlorine retention.

Some of the characteristic advantages of polyethylene waxes are:

  • High softening point
  • High melting point
  • Excellent thermal stability
  • High chemical resistance
  • Highly compatible with wax varieties
  • Perfect lubrication
  • Perfect heat resistance


Softening is an important finishing process in printing and dyeing. In this process, after repeating treatments, the hand feeling of fabric becomes rough. This is because, with more and more high-speed machining used in the textile industry, the attrition between the fabric and equipment increases, leading to more abrasions of the fabric. The use of textile softeners can avoid this friction. Textile softeners are one of the most widely used agents in dyeing and finishing.

The right type of softener should be selected after considering the composition and properties of the textile substrate. Generally, cationic and silicone based softeners are preferred for softness and substantivity.
Polyethylene competes with silicones in offering the best lubricity. Anionic and amphoteric softeners distinguish themselves in offering hydrophilicity. Hence choosing a proper mix of a variety of softeners is very important.

There are many advances in the field of softening finishes and the formulations are now modified taking into account their application on a variety of textile blends and the demand for multiple performance properties.

Sodium glucoheptonate

Sodium glucoheptonate is used as a chelating agent in compositions for cleaning glassware and metals, paint stripping compositions, boiler scale removing compositions. Glucoheptonates and gluconates are biodegradable complexes/chelates that are useful as an alternative for very high pH solutions, especially for Fe+3 and Cu+2. Sodium glucoheptonate is usually sold commercially in solution because it becomes a tacky substance on drying.


Esters are formed by the reaction of two reactants which are alcohols and acids, which is called an esterification. Fischer esterification is the classic synthesis for producing esters.

Esters are carboxylic acid derivative compounds. They are slightly soluble in water because of their ability to participate in hydrogen bonding. They are generally safe to use, with low toxicity.

Few essential oils have esters as their main components, esters are found in greater numbers than other functional groups. These esters with characteristic odors are used in synthetic flavors, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes; for this purpose, large quantities of ethyl acetate and butyl acetate are commercially produced.

Esters hydrolysis which in the basic medium is called saponification reactions even if the soap is not formed. Therefore, they are often preferred as a cleaning agent.


Esterquats are a widely used class of cationic surfactants. Esterquat compounds are synthesized and their surface behavior, antibacterial activity, and textile softening properties are used. Easily found cheap material is used to synthesize cationic fabric softeners. This fabric softener will be good for commercially and industrially important because of their emulsify activity, re-wettability dispersing power, and softness.


PEG is the common abbreviation for polyethylene glycol, which is water-soluble, non-toxic, non-antigenic, and biocompatible. PEG is commercially defined by its molecular weight such as PEG-600 or PEG-1000 etc. Since many PEG types are hydrophilic, they are favorably used as penetration enhancers, especially in topical dermatological preparations. PEGs and their derivatives are broadly utilized in cosmetic products as surfactants, emulsifiers, cleansing agents, humectants, and skin conditioners.

PEG and its derivatives are extensively used as lubricants, softeners, conditioning agents and antistatic agents for processing as well as finishing aids for textiles. Apart from this, the usage is also considered optimum for carding, spinning, knitting and weaving the fibers.
