Automation in textile finishing industry is not a new concept, but it is being modern day by day. The textile factory is characterized by a considerable fragmentation of the production cycle into a number of segments specialized in the production processing of different fibres/yarns; even the single steps of automated production are often considerably fragmented, which entails the need for them to be perfectly organized for guarantee good final results of automated production. The Initial steps for production of the textile cycle are less fragmented but fragmentation unquestionably increases during the finalized finishing stage, for this reason the large amount of processes required by the market. Modern automation technologies for textile finishing based on electrical and electronics, computer programmability and smart systems show great potential for textile applications and currently aim to the achievement of important objectives such as flexibility and quality, according to three reliable paths:
1) The automated standardization of components
2) The automated compatibility of systems
3) The popularity of personal computers in case of textile finishing.

The automated standardization of components takes place thanks to the concentration of automation technologies in some basic types of automated processes which must be done by the mechanical forces by machine. The machine is defined and summarized by a system made of inputs and outputs for automated textile production system. Inputs of textile production are sensors which transform the physical variables of the system into electrical values which can be read and processed by an electrical and electronic unit. Outputs of automated production are the actuators controlling the machine and consequently the process (motors, solenoid valves, thermo resistors).

Any system may usually refer to this operating scheme and can be controlled by making inputs operating in relation to the state of the output and following a preset sequence of times. The computer, by means of the appropriate automated operating software, supplies the logical links between inputs and outputs and controls the right operating sequence for Automation in textile finishing industry.

Through its gradual introduction, automation has affected:

1. Machines: the immediate objective was the reduction and simplification of the operator’s tasks;
2. Processes: the subsequent evolution stage has ensured the links between the various production steps with the automatic control of the textile mill, leaving the operator with only control and supervision tasks. The full insolvency of the different production areas (inventory control systems, preparation of dyes and auxiliaries, dyeing equipment, material storage, etc) and /or services such as planning, laboratory, design pattern development, technological planning of cycles and production still needs to be addressed. The most advanced integration solutions available today are mainly production cells.

The main difference between automated systems essentially lies in the quantity of variables controlled. Here are the finishing segments most affected by technological development:
1. Color analysis
2. Process control
3. Production control systems
4. Color kitchen
5. Automated inventory control systems
6. Transport and robotized systems
7. Machine control systems
