Oligomer & the importance of Oligomer remover-------
Oligomer is a smaller chain length of polyester made up of two or more molecules of basic ethylene terephthlate i.e. dimer or trimer, produced as a side reaction during the manufacture of polyester. The Oligoester because of its smaller chain length is in the form of a fine powder which is entrapped is basic polymer and migrates to the surface during high temperature polyester dyeing.
Higher the depth more is the displacement of Oligomer to the fibre surface. Typically polyester fibres contain between 1.5-3.5% by mass of low molecular esters, the principal oligomer being cyclic tris (ethylene terephthalate) with smaller quantities of dimer, pentamer & other compounds. Approximately 0.1 % to 1.0 % of Oligomer is produced as a side reaction in the manufacture of basic polyester.

The report outlines the process for determining an optimal dye recipe, including selecting dyes, calculating recipes from calibration data, selecting the best recipe, and modifying it based on dyeing tests until the color match is close enough.
Garment dyeing is the cost effectiveness of mass producing identical garments of particular colors.Garment dyeing is the process of dyeing fully fashioned garments (such as pants, pullovers, t-shirts, jeans, sweaters, dresses, bathrobes, casual jackets, shirts, skirts, hosieries) subsequent to manufacturing, as opposed to the conventional method of manufacturing garments from pre-dyed fabrics. A major drawback with this approach is the risk associated with carrying a large inventory of a particular style or color in today's dynamic market. Garment dyeing has been slowly emerging as a process to meet the ephemeral fashion trends adopted by the consumers and new machines and methods have made this process to wear a brighter future for it.The advantage of this process is the cost effectiveness of mass producing identical garments of particular colors.
Quick Response to the market (bar coding etc.,)
Ability to supply a wide range of colorations to the retailer, but only in the shades that are selling
Reduced discounted sales at inventory
Best way to achieved relaxed, casual look .Ability to create special effects such as tie dyed, pigment dyed and washed down in a single process etc.,
A major drawback with this approach is the risk associated with carrying a large inventory of a particular style or color in today's dynamic market.
Traditionally,
Oligomer is a byproduct of polyester manufacturing made up of small chains of ethylene terephthalate molecules. It is difficult to remove from polyester fibers and can cause issues during dyeing and spinning such as duller shades, dye spots, and clogged machine parts.

Dye is a coloured substance that chemically bonds to the substrate to which it is being applied. This distinguishes dyes from pigments which do not chemically bind to the material they colour. Dye is generally applied in an aqueous solution, and may require aftertreatment to improve the fastness of the dye on the fibre.
Dyes are usually soluble in water whereas pigments are insoluble. Dyes selection is very important when dyeing different types of textile fibre. Types of chemical dyes are Direct, Reactive, Vat, Sulphur dyes etc. All dyes required different chemical auxiliaries and different after treatment process. Each dyes possess different light, washing & rubbing fastness and having different characteristics also.
Scouring is the process of removing natural and added impurities from textiles using alkali solutions. The main objectives of scouring are to make the fabric hydrophilic, remove oils, waxes and other impurities, increase absorbency, and prepare the fabric for downstream processing. Scouring works through saponification of oils and emulsification of waxes. The scouring process depends on factors like fiber type, fabric construction and intended dyeing process. Common scouring methods include batch processing in kiers or continuous processing in jigs or boxes. Souring involves treating the scoured fabric with acid to neutralize residual alkali.

Scouring is the process of removing natural and added impurities from textiles using alkali solutions. It makes fabrics hydrophilic and absorbent. There are two main methods - batch/discontinuous scouring using kier boilers, and continuous scouring using J-boxes. Key steps involve saponification of oils and emulsification of waxes. Souring neutralizes residual alkali on scoured fabrics using acids.
Scouring is the process of removing natural and added impurities from textiles using alkali solutions. It makes fabrics hydrophilic and clean. There are two main scouring methods - discontinuous kier boiling and continuous j-box scouring. Kier boiling involves loading fabric into a heated vessel and spraying alkali solution onto it over several hours. J-box scouring passes fabric continuously through an impregnation box, preheater and j-box where it is stored in alkali solution. The main objectives of scouring are to remove oils, waxes and other impurities, increase absorbency and prepare fabrics for downstream processing.
Bio-scouring uses enzymes instead of harsh chemicals to remove impurities from cotton fabrics. It requires only one bath, saving 4 baths compared to conventional scouring. This leads to significant water savings of around 28 liters per kg of fabric processed. Bio-scouring also provides quality, economic, and environmental advantages over traditional scouring by reducing chemical usage, saving energy and time, lowering water consumption and effluent generation. Test results showed bio-scouring achieved satisfactory absorbency levels for dyeing while maintaining fabric strength without excessive weight loss.
