It includes : (1) Monofilament (monofil) of less than 67 decitex. (2) Multifilament obtained b grouping together a number of monofilaments (varying from two filaments to several undred) general1 as they emer e from the s innerets. These yarns may be without twist or twisted (sing e, multiple (fol ed) or cablcdf They therefore Include : i r f (i) Single yarns consisting of the filaments reeled parallel without twist. Filament tow not provided for in Chapter 55 is also included. (ii) Single yarns of such filaments twisted as they are taken from the spinnerets or in a subsequent twisting operation. h (iii) Multiple (folded or cabled yarns produced by combining such single arns, including those obtained om the monofilament of heading 54.04 (see Part ({ (B) (I) of the General Explanatory Note to Section XI). The above arns are, however, excluded if they constitute twine of heading 56.07 or yarn put u for retail sale ofheading 54.06 (see Parts (I)(B) (2) and (3) of the General Explanatory Note to Section %I). r In addition to the normal forms in which textile arns ma be put up other than for retail sale, some yarns of this heading may also be put up in o m s wi out internal support (cakes, etc.). .L Apart ffom the exclusions already mentioned, the heading does not include : (a) Synthetic monofilament and strip and the like of synthetic textile materials, of heading 54.04. (b) Synthetic filament tow of a length exceeding 2 m of heading 55.01. (c) Synthetic filament tow of a length not exceeding 2 m of heading 55.03. (d) Tops (~ptUredtow) of heading 55.06. (e) Metallised yarns, including yarns of this heading combined with metal thread in any proportion or covered with metal (heading 56.05).
Subheading Explanatory Notes. Subheadings 5402.31 to 5402.39 Textured yarns are yarns that have been, altered by .a mechanical. or physical process (e.g., twistin untwisting, fal~*s@g, compress~*n,rufflmg, heat-sethn or a combmation of several of these processe$: which results in md~vldualfibres bemg set etth inwducd cwls, critnps, loops, etc. W e distortions may be partially or corn letely straightened by a stretching force but resume the shape into whch they have been set upon being release i. Textured yarns are characterised by having either a high bulk or a very h extensibility. The high elasticity of both types makes them es ecially suitable for use in the rnanuf@' acme of stretch arments (e-g., tights, hose, underwear) while the &ighbulk yarns give fabrics softness and warmth of toucf. Textured yarns may be distinguished fiom non-textured (fla~)filament yams by the presence of special twist characteristics, small loops or reduced parallel orientation of the filaments in the yarn. Subheading 5402.46 This subheading covers arns consisting of fibres whose molecules are partially oriented. These yarns, which are generally in a $at form, are not used directly for the production of fabm and must first undergo a drawing or draw-texturing process. They are also known under the name " POY ". -
1.- Throughout the Nomenclature, the term “man-made fibres” means staple fibres and filaments of organic polymers produced by manufacturing processes, either : (a) By polymerisation of organic monomers to produce polymers such as polyamides, polyesters, polyolefins or polyurethanes, or by chemical modification of polymers produced by this process (for example, poly(vinyl alcohol) prepared by the hydrolysis of poly(vinyl acetate)); or (b) By dissolution or chemical treatment of natural organic polymers (for example, cellulose) to produce polymers such as cuprammonium rayon (cupro) or viscose rayon, or by chemical modification of natural organic polymers (for example, cellulose, casein and other proteins, or alginic acid), to produce polymers such as cellulose acetate or alginates. The terms “synthetic” and “artificial”, used in relation to fibres, mean : synthetic : fibres as defined at (a); artificial : fibres as defined at (b). Strip and the like of heading 54.04 or 54.05 are not considered to be man-made fibres. The terms “man-made”, “synthetic” and “artificial” shall have the same meanings when used in relation to “textile materials”. 2.- Headings 54.02 and 54.03 do not apply to synthetic or artificial filament tow of Chapter 55.
