ABSTRACT

This thesis is essential because it intends on solving the problem of space, time, and

economy encountered when using the flat fabric inspection table and advanced fabric

inspection machine and in addition to this it will try to increase the quality of fabric.

Small scale industries in textile and garment Plants inspects fabric on flat fabric

inspection table and most of them do not use any mechanisms to solve the above

problems. Thus they are wasting key elements that affect the profitability of industry.

Therefore this paper triest design a fabric inspection machine which is manually driven

that is economical effective and efficient in operation. Before we go directly to the

design of the machine a brief introduction on the basic concept of fabric inspection

machine, its and benefit will be provided so that the readers has a clear picture why we

do finally a number of features of the machine are given for the readers and this paper

can be used as a lead for future research works in the field.

BACK GROUND OF THE RESEARCH

Introduction

Fabric inspection is the visual examination or review of fabrics that received from

supplies in relation to some standards, specification or requirement. The cost impact of

defect can be greatly reduced by detecting the defects early as possible. Fabric

inspection determine its acceptability from a quality view point, otherwise extra cost

may be incurred due to either the loss of material or time. The quality of the final

garment depends on the quality of a fabric when it is received as a roll.

BASED ON TECHNOLOGY

Fabric inspection is done either manually, semi automatically and fully automatic. It

depends on the technological development and types of fabric roll.

Manual inspectionIt is suitable to folded cuttled fabrics done on a large (long) flat table due to the size of

the table it needs large spaces. All activities are performed by the operator; it is low

productivity and inconsistence due to the fatigue of the operation.

Semi-Automatic Fabric inspectionIt performs some of the operations automatically and the rest are responsible of the

operator or inspector. Mostly the following operations performed automatically width

and meterage measuring system. Defect analysis and detection may not performed by

the machine. It is more productive and costly than the manual inspection.

Fully Automatic fabric inspection machine

The automated fabric inspection systems are based on adaptive neural networks. It is

most productive and consistence, the most costy system. Due to the above reason: Ther

is a need for cheaper and efficient inspection machine. This machine should be afforded

by small scale textile and garment industries.

OBJECTIVE OF THE RESEARCH

The objective of this study is to design a fabric inspection machine which has less cost,

minimum space consumption, effective and efficient in operation for the user.

STATEMENT OF PROBLEM

Globalization has brought the planet together ; and Ethiopians small scale textiles and

garment industries are highly related with the outside world, and they are more and

more manufacturing products for local and foreign customers; therefore benchmarks fo

quality and sped are being set very high. With everything in mind the majority of them

are not using the proper material or following the proper techniques in order to achieve

the standards. This problem is related with the lack of awareness or capital. Some knowthe existence fabric inspection machine but they do not have the required capital to buy

it, others do not know its existence. In the production of fabric, a number of fabrics in

the form of cutteled fold are inspected on the long flat fabric inspection table and the

rolls of fabrics are inspected on the semi-automatic and fully automatic inspection

machine. The manual fabric inspection system has a disadvantage of high space

consumption due to its length, in consistence and fatigue and the cost of semi-automati

and automatic inspection machine is very high then small scale industries do not afford

the cost of those machines and also as developing country there is less tendency to

produce industry machineries within the country: due to reason there is a need of

inspection machine which have less cost, minimum space consumption, effective and

efficient in operation.

SCOPE OF THE RESEARCH

The scope of the research started from idea development to the design stage.

BENEFITS AND BENEFICIARIES

Many organs will beneficiate from the inspection machine that will be designed. They ar

two major beneficiaries of these research, they are small firms / micro enterprise in

textile and garment industry. These two beneficiaries will also benefit by using thisresearch; those are:

Reduce the cost of electric power to run the machine. Reduce foreign currency that paid to the imported machine. Since the inspectio

machine will be manufactured locally and create job for the communities

opportunities.

Transferring technology to small firms /micro enterprise and also save spaces insteady of the long fabric inspection table. All this will help the industries to

accomplish the required excellence. Thus it results in higher profitability. In

addition to these two organs there are many other organization that benefit

indirectly from this research for instance researchers or graduate students may

use this research as an element while they are doing their research.

METHODOLOGY

LITERATURE REVIEW

Fabric inspection machine is the tools to improve/control fabric quality by the process

know as inspection. Most researches have only focused on semi-automated and fully

automated fabric inspection machine for the industries /factories. The tradition fabric

inspection (:.e the flat cannot be used for the rolled fabric it is difficult to inspect the rol

fabric.

Regarding to quality of row materials and products (output products) fabric inspection is

one of the critical issue in textile and garment industries. These are different types or

models of semi-automated and fully automated fabric inspection machine which have

different parts and functions.

For manual inspection system :_ It has long table for inspection area.

_It has 4 or 6 legs for holding the table.

_The number of legs depends on the length of the table.

Most semi-automatic and fully automatic fabric inspection machine is_In dependently controlled unwind and rewind cradles with electronic synchronization

for tension free rewinding wit out stretching for woven and knitted fabrics.

_Automatic edge guide system for accurate rewinding in order to reduce selvage during

cutting.

_In dependent over head lamp and rear light box with three illumination levels.

_Electronics counter for measuring (in feet, yard or mater).

_caster for mobility.

_Automatic stop features at the end of the roll.

_additional start /stop buttons in center of over head lamp assembly.

Basically the manual fabric inspection machine is consists of wooden frame, roller

for holding the fabrics roll and to control tension of the fabric during inspection.

TYPES OF FABRIC INSPECTION MACHINE

Based on the types of fabric there are two major categories of fabric inspection machine

those are woven and knitted fabric inspection machine. We manufacture and offer to

our clients a wide range fabric inspection machine that is suitable for woven and knitted

fabric. Those machines have lighting arrangement at the top or at the bottom. Available

at industry leading rates, we offer these machines in both standard and customized

finishes.

WOVEN FABRIC INSPECTION

Due to the increasing demand for quality fabrics, high quality requirements are today

greater, since customer has become more aware of non quality problem. In order to

avoid fabric rejection, we have introduced fabric inspection machine. The description on

knitted fabric inspection machine is the same as woven fabric inspection machine.

Other specification of knitted fabric inspection machine:

_For ward/reverse running.

_Working width as per client requirement.

_Various options of fabric input and output.

_Option edge guiding device.

DESCRIPTION OF FABRIC INSPECTION MACHINE

Fabric inspection machines are used to inspect fabric quality. These machines measures

the fabric using different parameters and these parameters can also changed according

to the fabric specification, features fully detachable body, portable with standard fitting

makes the installation of this machine easily.

WHAT IS THE CONCEPT WHEN USING FABRIC INSPECTION MACHINE

The diversity of fabric quality and kinds of making up demands of an inspecting machine

also a multiplicity of different main and secondary functions for this purpose, the

inspection machine has continuously developed and perfecting their fabric inspecting

and make-up technique by carefully studied and variable modular design from the simp

long flat table to the automated fabric inspection machine.

HOW TO DESIGN FABRIC INSPECTION MACHINE

It is design based on the fabric types (knitted or woven); then analysis the existing flat

fabric inspection table, semi automatic and fully automatic fabric inspection machine.

From this we can design fabric inspection machine by modifying the existing fabric

inspection machine. This machine is designed so that the roll of fabric can be mounted

behind the inspection table under an adequate light and re rolled as they leave the table

FABRIC INSPECTION MACHINE DIAMENSION

The dimension of the machine /fabric inspection machine is determined by the width of

the fabric. There are Varity of fabric inspection machine, width Varity (dimension)

183cm-210cm is the standard width for fabric inspection machine.
