The web belt adopts pneumatic fastening to ensure constant tension in the stopping modes of machines. This belt adheres to pneumatic correct system for correcting the path in a reliable way. In addition to this, every belt is accurately managed by separately inverter to ensure adaptable speed. The drying chamber of the machine provides two layers filtering net having 40mesh and stainless steel design. The frame of the machine is developed using high-grade carbon steel square pipe. Moreover, temperature insulated material is also included in the machine for minimizing the energy loss.
The P structured silicon rubber seal is temperature resistant that reduces the heat loss in maximal degree and saves energy even in upper limit.

    Tubular Compactor Machine

    Tubular compactor machine has four basic sections, the entry section, the edge driver section, the compaction section and the output section. Tubular compacting machine is used after  hydro extractor,  dewatering machine  and  textile dryer. By this compactor machine, compacting is done for control the shrinkage of the fabric. Here, different types of off line quality of the fabric are measured. In this article I will discuss about functions, parts, working principle, parameters and specification of tubular compactor machine.

    Functions of Tubular Compactor:
Following objectives are achieved by the tubular compactor. They are-

            Shrinkage of the fabric  is controlled by the compactor.
       
            Fabric width is controlled by the compactor.
       
            GSM of the fabric  is adjusted by the compacting.
       
            Fabric smoothness is achieved by the compactor.
       
            Heat setting of fabric for Lycra is done by tubular compactor.
       
    Important parts of Tubular compactor machine:

            Over feed roller
       
            Steam Sprayer
       
            Stretcher
       
            Cylinder
       
            Blanket
       
            Teflon cover
       
            Folding device
     
The fabric feed from the feed roller under a slack condition is heated and moistened by steam and delivered to double compacting units fitted one above another for compacting both sides of the tubular  knitted fabrics. Each compacting unit consists of an endless blanket, a hot metal shoe and a big hot metal cylinder, as in the case of Sanforising units. The compacted fabric is delivered on a trolley.

    Heat setting

    Heat setting  is a term used in the  textile industry  to describe a thermal process usually taking place in either a steam atmosphere or a  dry heat  environment. The effect of the process gives  fibers,  yarns  or fabric dimensional stability and, very often, other desirable attributes like higher volume, wrinkle resistance or temperature resistance. Very often, heat setting is also used to improve attributes for subsequent processes.

            Heat setting is carried out to bring the material to it’s thermal equilibrium the material wouldn’t changes it’s morphology it’s kept at that temperature for a long. ? Heat setting is also known as ANNEALING. ? The degree of set, a term often used to describe the extent of heat setting is the measure of how close the material has moved to a thermal equilibrium. A 100% set material is considered to be at its thermal equilibrium at a given temperature.
       
            Mechanism of Heat Setting ? The setting temperature used is above Tg. In heat setting, inter-chain bonds, such as hydrogen and dipole bonds, break. This allows the molecular chains to move and adopt new, stress-free positions. New intermolecular bonds then form with the fabric in a relaxed condition at the setting temperature. After cooling, the polymer molecules in the filaments become frozen in place. The new bonds are stable up to the heat setting temperature. The reorganized internal polymer structure, and the material’s dimensions, will be stable.
       
            Objectives The objectives of heat setting processes include structure homogenization and the elimination of internal tensions within the fibre resulting in reduced shrinkage, improved dimensional stability, reduced creasing propensity and reduced edge-curl in woven and knitted fabrics. To this extent, the process may be better described as thermal relaxation. Heat setting changes not only the mechanical, but also the dyeing properties of man-made fibres. The principle is based on heating the fibre within a fibre-specific temperature range which is limited at the upper end by the melting point (softening range) and the respective glass transition temperature (necessary to break the secondary bonds) at the lower end.
       
    Parts, Functions and Working Process of Stenter Machine

    Stenter is the most expensive and important fabric drying and finishing machine. Stenter is a machine or apparatus for stretching or stentering fabrics. It is also known as a ‘tenter’ in the woollen industry. The purpose of the stenter machine is to bringing the length and width to pre-determine dimensions and also for heat setting and it is used for applying finishing chemicals and also shade variation is adjusted. The main function of the stenter is to stretch the fabric widthwise and to recover the uniform width.

    Stenter machine consists of two endless auto-lubricated driven chains, typically 40 to 60 m in length carrying pins or clips to hold the fabric edges while passing through a number of hot-air chambers (3–5, each of about 3 m). Hot air is directed onto the fabric equally from above and below. A stenter has the provision for overfeeding the fabric to allow required shrinkage during  heat setting of fabric  while the width is increased to the precisely specified value by the chains. The use of clip stenter has declined because of the difficulty of applying overfeed. The stenter speed ranges from 10 m/min for heavyweight furnishing fabrics to 100 m/min for lightweight dress-goods.

    Open Width Compacting Machine
Open width compactor machine is used for compacting the open form fabric. Here,  slitting machine  is used for open the fabric from the tubular form. Open width compacting machine is a combination machine of pin plate stenter and felt compactor, it is used for the processing of 100% cotton, wool, hemp natural fabrics and chemical fabrics in open width form. It is also used in continuous spreading, centering, pinning fabric selvedge on needles, widening with overfeeding and correction of the weft and width, steaming, gumming, drying,  trimming  fabrics selvedge, steaming, calendaring, cooling and rolling-up with automatic alignment of the fabrics roll edge or folding in carriage. The open width compacting machine allows to get high shrinkage values. The compacting is suitable to treat 100% cotton knitted fabric type jersey, pique, interlock, plush, rib fabric, dyed and or printed fabrics and union fabrics. Working width can be 2400mm. In this article I will discuss about functions, parts, working principle, parameters and specifications of open width compacting machine.
