The order of interlacement of warp and weft threads at right angles is known as structure of woven fabrics. The interlooping system of yarns is known as structure for knit fabrics. Classification of woven fabric structure: Simple structure and Compound s of fabric representation: Warp overlap in which warp is above weft and Weft overlap in which . In a system for air-jet texturing yarn a yarn treating jet is modified to locate a baffle at the outlet end of the jet. The baffle is positioned a fixed distance from the central axis of the jet and away from the outlet end of the jet such that the yarn follows the surface of the baffle to a point where the yarn leaves the baffle to pass back through the air stream exiting the jet to eliminate Cited by: 9.

The air-jet texturing (AJT) and intermingling (INT) processes are two applications of air jets used to modify the structure of synthetic multifilament yarns.

The modification is performed by high-speed jets, which are created by purpose designed nozzles. The air-jet texturing (AJT) and intermingling (INT) processes are two applications of air jets used to modify the structure of synthetic multifilament yarns.

90 E, DS 60 D and DS 90 MFB air-texturing units. All of them are primarily designed to texture glass fibers and artificial grass. They use Heberlein and custom in-house jets for air-texturing textile bobbins, spin cakes and direct rovings. Except for DS 90 MFB, which has a maximum production speed of m/min, the other models have.

(1) Use of air jets to create turbulence to entangle the filaments of continuous filaments yarns, without forming loops, after extrusion. Provides dimensional stability and cohesion for further processing but is not of itself a texturing process.

It is compatible with high-speed spin-drawing and high-speed take-up. The rectangular cross-section and the two-piece construction of the nozzle design, common features in both the texturing and intermingling nozzles, facilitate both manufacture and maintenance.

Another novel feature of the design is that the air inlet duct spans across the full length of the main channel. Cost conscious modern industry needs a compacting process that will be carried out during the yarn production stage whether it will be spinning, drawing, texturing or winding.

The use of cold air jets appears to be an ideal solution and the intermingling is expected to replace all the other compacting or other compacting techniques available today and in near future[3]. Types of air jets Texturing nozzles are usually enclosed in a chamber not only to reduce the noise but also to collect the used water & some of the spin finish washed away from the filaments during the texturing nozzles have an impact element at the nozzle exit to be used optionally in certain cases recommended by the manufacturer.

Intermingling is a process of imparting inter-filament cohesion by entwining the filaments instead of addition to inserting twist. The entwining is usually achieved by passing the yarn under light tension through the turbulent zone of an intermingling jet (nozzle).

Air-jet texturing is a well-established filament yarn processing technology that has been around for more than half a century. There is much debate about various aspects of the process in the literature such as the mechanism of loop formation, role of water in air texturing and the influence of process variables on air textured yarn by: 4.

yarns produced using various currently used commercial jets have been compared. The results show that the performance of cylindrical jets and Taslan type XX jet for parallel end texturing of 76 denJ36 fil polyester yarns is superior.

The HemaJet-EO52 is used in the production of high quality bulky air-textured yarns such as polyester, nylon, polypropylene, and glass fibres. The HemaJet-LB04 jet housing is made of robust, impact-proof material and is suitable for all air-texturing processes. The KF jet insert is the optimal solution for knot-free air interlacing of DTY yarns.

Air Texturizing Process And Fabric The air texturing process was developed about 50 years ago.

However, it took nearly 30 years before the first commercial machine for the production of air jet textured apparel yarns was displayed at ITMA in The air texturing process transforms flat multi-filament yarns into yarns with a spun like character.

In the s, the Heberlein Fiber Technology Inc. launched the HemaJet T jet core range. Since then it has been possible to texture using air-jets at up to meters per minute.

Attempts were made to develop faster jets but higher speeds were only achieved at the expense of quality, especially. This important book summarises the key principles, technologies and process issues in the manufacture of high-quality false twist textured yarns.

After an introductory chapter on the development of textured yarns, the book reviews yarn texturing machine designs and twist application methods, including air jet mingling and machine variants for. The object of the work was to develop the use of high-pressure steam in order to replace air in air-jets in the production of intermingled yarns, particularly for sewmg threads.
