    to the production conditions, we used a double-sided RPR false-twist texturing machine (Model 3SDXP, made in Italy) with positions on either side as shown in Figure 2. Polyurethane (PU) disks (configuration ) were used for false twisting. The maximum speed of this texturing machine was m/min. The yarn moved along a straight line,File Size: 1MB.

Carolina, March 23– False-twist texturing: a process in which a single filament yarn is twisted, set and untwisted. When yarns made from thermoplastic materials are heat-set in a twisted condition, the deformation of the filaments is "memorised" and the yarn is given greater bulk.

False Twist Textured Yarns: Principles, Processing and Applications (Woodhead Publishing Series in Textiles)5/5(1). 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 "False Twist" texturing principle Think about holding a rubber band between two clamps and twist this band by turning it in the center.

You will observe real twist on the left as well as on the right hand side. But each side is twisted into the opposite direction.

One side is S- the other side is Z-twisted. Start studying Yarn Processing. Learn vocabulary, terms, and more with flashcards, games, and other study tools.

Stretch Yarn: False twist and Edge crimping method is used to produce this type of yarns having to percent elongation. In the first method, the yarn is twisted, heat-set, and untwisted to get a coiled yarn.

In the second method, the hot filaments are drawn over a knife like edge, which flattens one side and causes the yarn to curl. A false twist textured yarn is a continuous filament yarn that has been processed to introduce crimps, coils, loops and other fine distortions along the yarn's length.

These distortions give synthetic yarns such as nylon, polyester and polypropylene improved properties such as stretch, bulk, improved thermal insulation and an appearance similar. Exam 3 Textiles Chapter 10 study guide by caitlinconley includes 26 questions covering vocabulary, terms and more.

less stretch than stretch of textured yarns. stretch. High degree of potential stretch and rapidrecovery: moderate bulk false twist process.

The yarn were textured at a first heater temperature of °C, °C and °C set in both false-twist texturing machines, the Muratec 33 H (Belt-type nip twisters) and Barmag FK 6 M Textured Yarns yarns of synthetic fibers that differ from ordinary textile yarns in their greater bulk, strong crimp, loose structure, and, in some cases, high stretchability.

The production of textured yarns stemmed from the need to broaden the area of use of synthetic fibers; applications of such fibers had previously been limited by the fibers’ low. A new method has been introduced to determine the crimp features of false twist textured yarns by applying computer vision and image processing method.

Hence, the test results, with accuracy, are achieved more quickly than by the other exciting by: 1. Get this from a library. False twist textured yarns: principles, processing and applications. [Colin Atkinson] -- A false twist textured yarn is a continuous filament yarn that has been processed to introduce crimps, coils, loops and other fine distortions along the yarn's length.

These distortions give. Air jet textured yarns may be textured on a single thread basis saving the doubling and sometimes re-doubling texturing economics are most favorable when installing a new production. The investment for air jet texturing is much less than for an equivalent capacity for spun yarns.

Textile - Textile - Types of yarn: Yarns can be described as single, or one-ply; ply, plied, or folded; or as cord, including cable and hawser types.

Single, or one-ply, yarns are single strands composed of fibres held together by at least a small amount of twist; or of filaments grouped together either with or without twist; or of narrow strips of material; or of single man-made filaments. Spun yarns usually have real twist, which holds the fibres together in the yarn.

False twist: When inserting false twist into a length of yarn, both ends of the yarn are clamped, usually by rollers, and twist is inserted with a false twister between the clamping points, as indicated in figure (b).

POY polyester yarns, but using other texturing pro-cesses [16,18,19]. In this paper, the effect of false-twist texturing parameters (texturing speed, heater tempe-rature, draw ratio and disc-to-yarn speed ratio (D/Y ratio)) on the structure and crimp characteristics of polyester yarn has been studied using a HT heater and high texturing Size: KB.

The Production of Textured Yarns by Methods Other Than the False-twist Technique - Textile Progress Vol 16 No 3 (Paperback) D. Wilson £ Paperback. technical-technological parameters in the false twist texturing process on structural characteristics of polyamide yarns was studied.

Partially oriented POY multifilament of 22f07×1 dtex fineness was textured under production conditions on the friction texturing machine ICBT, model FT 15 E3. Using low temperature long heaters, the.A yarn that has been so processed as to introduce durable crimps (q.v.), coils, loops or other fine distortions along the length of the fibres or filaments.

NOTE: a) The main texturing processes usually applied to continuous-filament yarns made from or containing thermoplastic fibres, are as follows: 1.moisture absorption, etc. Texturing methods have been developed to overcome this problem. False-twist texturing method is the most common process. False-twist texturing process can be investigated based on three main parameters, which are called 3t: tension, twist, and temperature.

The properties of the textured yarn can be altered by changing.
