This modern Tensionless Relax Dryer is widely used for open and tubular width knit fabrics. This is provided to ensure advanced output with its easy to operate features and high durability. It comes with a fabrics infeed section having different features such as turbine-worm gear box, infeed box, axis roller, pneumatic tension device, etc. The overfeeding roller motility is designed to move frequently and reliably with its easy to operate features. This comes with the overfeeding motion that is precisely controlled by inverter.

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-

1. Shrinkage of the fabric is controlled by the compactor.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.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.
