Garments Dyeing & Machine Specification

INTRODUCTION

 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

SEWING MACHINE which are used in Garments Industries # 01

Sewing is a creative and interesting skill. The knowledge of sewing give a confident feeling when it is applied to the construction of garments. The earlier method of sewing by hand is not applicable for all stages of garment making. Therefore, considerable emphasis is given to machine sewing. There are several machines in the market today, each with its own desirable features and advantages. Sewing machines range from most basic having only simple lock stitch to the electronic machines that use advanced computer technology having various functions for

Example : piping, binding, ruffling, pleating, darning, hemming and even making buttonholes and attaching fasteners. A good sewing machine is required to obtain quality products. One has to be familiar with the characteristics of different types of machines for selecting appropriate machine, depending upon the ability and requirements of the person. 

1.1 TYPES OF SEWING MACHINES:

Sewing machines are now available in various models such as domestic model, tailor model, industrial model, portable and cabinet models. They may be operated by hand, treadle or electric motor.

FABRIC PREPARATION PROCESSES : YARN PREPARATION EQUIPMENT

Various types of equipment can be used for preparing fabric. The ultimate goal of any preparation process is to produce fabric that is clean and rid of all impurities that interfere with dyeing and finishing. The preparation steps can be carried out as either batch or continuous processes. The fabric may be transported as a rope or as an open sheet through the equipment. The choice is often predicated on the dyehouse itself. The distinguishing feature of batch equipment is that all of the fabric is simultaneously submerged in the liquor. The fabric is agitated by moving it through the

Fabric preparation for dyeing

The term "Preparation" has two implications in textile processing. In greige manufacturing, it is used to describe the processes which prepare yarns for weaving and knitting. Mostly, it is used to describe slashing operations that ready warp yarns for weaving. In dyeing and finishing, the term is used to describe those processes that ready fabrics for the steps that follow, coloration and finishing. Fabric
preparation is the first of the wet processing steps where greige fabric is converted into finished fabric. The steps that follow, dyeing or printing and finishing, are greatly influenced by how the fabric is prepared. Improper preparation is often the cause of problems encountered in the dyeing and
