FINISHING OR DRESSING OF FILAMENTS, YARNS, THREADS, CORDS, ROPES OR THE LIKE (curling or crimping D02G; by treatment with liquids, gases or vapours D06B; finishing other than by liquid treatment, of yarns in warp or sheet form D06C; for chemical matters, see D06L, D06M, D06P, D06Q; treatment during rope-making, apparatus for treating ropes auxiliary to rope-making D07B)
Definition statement
This subclass/group covers:

Changing the physical characteristics or properties of filaments, yarns, threads, cords, ropes or the like

Relationship between large subject matter areas

There maybe an overlap with D02G 1/00; crimping and curling of fibres, filaments and yarns. For chemical matters, see D06L, D06M, D06P, D06Q; treatment.

References relevant to classification in this subclass
This subclass/group does not cover:
Producing crimped or curled fibres, filaments, yarns or threads, giving them latent characteristics
Treatment with liquids, gases or vapours
Finishing other than by liquid treatment, of yarns in warp or sheet form
Chemical bleaching, dry-cleaning or washing fibres, threads, yarns, fabrics
Dyeing or printing textiles
Decorating textiles
Treatment during rope-making, apparatus for treating ropes auxiliary to rope-making
Details of, or auxiliary devices incorporated in rope-making machines for softening, lubricating or impregnating ropes or component strands thereof

Treatment, not provided for elsewhere in class D06, of fibres, threads, yarns, fabrics, feathers or fibrous goods made from such materials
Glossary of terms
In this subclass/group, the following terms (or expressions) are used with the meaning indicated:
Bulking
making the filaments and yarns more voluminous by changing the structure
Slub
a thick lumpy knot along the length of the yarn
Drawing
stretching and elongating the yarns or filaments
Draft
the amount to which the yarn or filament is drawn
Fibre
a relatively-short, elongated member of natural or artificial material
Filament
an endless or quasi-endless, elongated member of natural (e.g. silk) or artificial material
Yarn
a unitary assembly of fibres, usually produced by spinning
Thread
an assembly of yarns or filaments, usually produced by twisting
Modifying the surface
Definition statement
This subclass/group covers:

Apparatuses and methods for treatments of finishing of filaments, yarns, threads, cords, ropes or the like by modifying the surface, e.g. by mechanical action through abrading or indenting the surface.

Informative references
Attention is drawn to the following places, which may be of interest for search:
Apparatuses and methods for treatments modifying, retaining, or restoring the physical form or cross-sectional shape, e.g. by use of dies or squeeze roller
by abrading, scraping, scuffing, cutting, or nicking (preliminary roughening of fibres, e.g. for spinning, D01G 3/00)
Informative references
Attention is drawn to the following places, which may be of interest for search:
Treatments for modifying the surface of textile fabrics by abrading, napping, teasing, etc
Glossary of terms
In this subclass/group, the following terms (or expressions) are used with the meaning indicated:
Scuffing
an abrasive wear
Nicking
is an abrasive wear by small cuts
Treating with particulate, semi-solid, or solid substances, e.g. wax (during package formation B65H 71/00; waxing yarns or the like as incidental measures during spinning or twisting D01H 13/30)
References relevant to classification in this group
This subclass/group does not cover:
Waxing filamentary material as additional measures during package formation
Waxing yarns in twisting or spinning machines
Cleaning, e.g. removing dust, loose fibres, charred ends (in combination with the shearing, singeing, or otherwise removing of projecting fibre ends D02J 3/12, D02J 3/14, D02J 3/16)
Informative references
Attention is drawn to the following places, which may be of interest for search:
Physical treatment of artificial filaments or the like during manufacture, i.e. during a continuous production process before the filaments have been collected
