The shrinkage of loop reduces the size of loop and the bulk decreases, where as in case of dry textured yarns the numbers of loops on yarn surface are lesser than pre-wet textured yarns. Air jet texturing is the most versatile of all known texturing methods that are used to convert filaments yarns to textured yarns. Airjet textured yarns .

Textured Filament Yarns BISFA 2 SCOPE These methods apply to textile textured filament yarns based on polyester and polyamide. Textile textured filament yarns are mainly being further processed through warp- and weft-knitting and weaving, whilst textured carpet yarns are mainly being further processed through Size: 45KB.
is not recommended for elastomeric yarns and those yarns that stretch more than 5 % under the tension loadings prescribed, although it has been used for the latter.
NOTE 1—Procedures for determining yarn shrinkage and bulk proper-ties of textured yarns are covered in Test Method D This test method shows the values in both SI andFile Size: 48KB.
The huge variety of filament yarns available on the market requires a correspondingly wide range of testing methods and equipment – both in industrial quality control as well as in research and development. In many fields, TEXTECHNO was the first to develop and produce testers dedicated to the special needs of those products.

This report was created for global strategic planners who cannot be content with traditional methods of segmenting world markets.
With the advent of a borderless world. For textured polyester yarns, Condition 3 (water bath at 97°C (°F)) is recommended. Only bulk shrinkage is calculated.
This test method for the measurement of bulk properties is not recommended for acceptance testing of commercial shipments because of lack of precision data. A process for manufacturing continuous polyester filament yarn for technical applications from a polymer over 90% of the chains of which are composed of-ethylene terephthalate units, via a one-step spinning process, with the undrawn filaments having a crystallinity smaller than 16% and the yarn being wound at a rate larger than m/ by: 6.

The word used to describe the size or weight of filament yarns. This booklet replaces two older standards: Internationally agreed methods for testing regenerated cellulose and acetate continuous filament yarns ( edition, see abstract /) and.
Note 1—For another method of testing crimp in textured yarns, refer to Test Method D This method may also be used for non-textured yarns. This test method is limited to crimped, multi-filament yarns ranging from to dtex (15 to denier) and for BCF yarns from to dtex ( to denier).

Softer yarns and fabrics are obtained than with conventional textured yarns while also providing improved adhesion and by: 1. Manufacturing Yarn: • A continuous strand of textile fibers, filaments, or material in a form suitable for knitting, weaving, or otherwise intertwining to form a textile material (ASTM Definition) Yarn Classifications SPUN YARNS Spun Yarns • continuous strand of fibers held together by twisting stable fibers Spun Yarn Characteristics • Fuzzy: fiber ends protrude along length of yarn.
Tex is an internationally agreed fixed length system (that is the weight per unit length) of yarn numbering that applies to all types of yarns, regardless of the method of production. The tex count represents the weight in grams per 1 kilometre ( metres) of Cited by: 2.
A generic term for a continuous strand of textile fibers, filaments, or material in a form suitable for knitting, weaving, or otherwise intertwining to form a textile occurs in the following forms: (1) a number of fibers twisted together (spun yarn); (2) a number of filaments laid together without twist (a zero-twist yarn); (3) a number of filaments laid together with a degree of.
Textured filaments or textured yarns are those such as described, for example, in “Encyclopedia of Polymer Science & Engineering”, Second Ed. at page and include, for example, false twist yarns, including, e.g., single heater stretch yarn and double heater set yarn, tangled/interlaced yarn, air jet (entanglement) textured yarn.
