Garments Dyeing & Machine Specification

Textile coloration is combination of same series processes such as scouring, bleaching, dyeing & after treatment which can be carried out at different stages of fiber processing in different forms like staple, yarn, fabric (rope or open-width, piece & garments) Dyeing of staple forms(loose fiber) is better for achieving better colorfastness, maximum penetration and uniform migration of dues over dyeing. Piece (batch) dyeing is carried out open width or rope form in depending on machine type & end-dyes. Usually these materials are dyed in exhaust dyeing method in a single dyeing machine. But lightweight woven fabrics & garments are also possible to dye with same principle in different form of dyeing machine such as jet dyeing machine. During garment dye process, some dyeing parameter should be adjusted according to form of products-righty weaved and heavy garments need the dyes with better migration properties, higher dyeing temperature, lower liquor ration & careful circulation of goods.

Usually, textile coloration is carried out impart attracting of textiles & pretreatment is first stage of textile coloration process, plats very role on coloring on textiles. Generally loose fiber, yarn, knit fabric, garment & very lightweight synthetic woven fabric are dyed batch wise in single machine. So the batch preparation is the early step of pretreatment in coloration process.

GARMENTS DYEING

This method is the best process of the dyeing of goods. However, the penetration of the dye solution may not be completely passed to the fibers such as between the seams, buttons, zippers etc. Normally, it is used for lingerie, socks, sweater dyeing etc.

In woven fabric processing generally various types of dying process is used. Those are:

i. Pad Dry Steam (PDS)

ii. Pad Dry Cure (PDC)

iii. Cold Pad Steam (CPS)

Machine required for those process:

i. Cold pad batch

ii. Thermosol

iii. Pad steam

Cold pad batch: It is the simple & easiest way of woven fabric dyeing. In this process only dark shade can be produced successfully & economically. But limitation is medium or light shade is difficult to match. It takes a long time because after dyeing it required a rotation of 8 to 12 hours.

Thermosol: It is a dyeing machine but it cannot produce the color as finally required or permanent. But in PDS process it can be provide finished product. By this machine only color is migrated from liquor to fabric. The it is dried on pre dryer & followed by hot air flow drying in thermosol unit. After this process color is developed in pad steam by chemical padding.

Pad stream: Thermosol run fabric must pass through pad steam for the development of color when CPS process is carried out. Here chemical padding is done through which color is fixed on the fabric. CPB run fabric does not require pad steam process. Here based on requirement additional dye can also added.
