Included here are : (A) Products and preparations used in the textile or like industries : (1) Preparations to modify the feel of products, for exam le : stiffening agents, enerally based on natural starch substances (such as starc?I of wheat, rice, maize corn) or potato and dextrin), muci aginous substances (lichens, alginates, etc.), elatin, casein, vegetable gums (gum tragacanth, etc.) or rosin; weightin agents; so tening agents, based on glycerol, imidazoline derivatives, etc.; fillers, ased on natural or synthetic high molecular weight compounds. f Y % f Jn addition to the above-mentioned basic constituents some of the preparations may also contain wetting agents (soaps, etc.), lubricants (linseed oil, waxes, etc.), filling agents (kaolin, barium sulphate, etc.) and preservatives (particularly zinc salts, copper sulphate and phenol). (2) Agents to produce non-slip and anti-snag finishes. These roducts are intended to reduce the slipping of fabrics to prevent the formation o snags in hosiery and knitwear. They are generally based on polymers, natural resins or sihcic acid. ? (3) Agents to produce dirt-repellent finishes. These are generally based on silicic acid, aluminium compounds or organic compounds. (4) Anti-crease and anti-shrink preparations being mixtures of chemically defined compounds with at least two reactive groups (e.g., bis(hydroxyrnethy1) compounds, certain aldehydes and acetals). (5) Delushin agents designed to reduce the lustre or loss of textiles. They generally consist o sus ensions of pigments (titanium oxi e, zinc oxide, lithopone, etc.) stabilised by ce lulose ethers, gelatin, glue, surface-active agents, etc. P f The reparations classified here should not be confused with paints (heading 32.08, 32.09 or 32.16,nor with lubricatingpreparations for oiling or greasing wool (headlllg 21.10 or 34.03). (6) Flame-retardant preparations based on ammonium salts, corn ounds of boron, nitrogen, bromine or phosphorus or on formulations based on c lorinated organic substances with antimony oxide or other oxides. A (7) Lustring a ents intended to produce lustre or gloss on textiles. They are generally emulsions o paraffins, waxes, polyolefins or polyglycols. f (8) Mordants prepared for use in textile dyeing and printin processes to fix the dyestuffs. These preparations, which are soluble in water, are usu ly based on metallic salts (e.g., aluminium, ammonium, chromium or iron sulphates or acetates, potassium dichromate, antimony potassium tartrate) or tannjn. (But see exclusion (d) at the end of this Explanatory Note.) (9) Dye carriers which are used to accelerate swelling of the synthetic fibres. The derivatives of benzene, hen01 or biphenyl-2-01, methyl hy oxytoluates surface-active agents. or not containing (10)Non-felting agents designed to reduce the felting of animal fibres. They are often chlorinating or oxidising agents or specialised formulations of synthetic resin-forming substances. (1 1)Sizing agents which are used to make arns more resistant during weaving operations. These preparations are generally base on starch, starch derivatives or other natural or synthebc polymer binders. These may also contain wetting agents, softening agents, fats, waxes or other materials. This group also includes emulsified warp sizing waxes and emulsified fats prepared for sizing. 6' . (12) Oil-re~ellentswhich are intended to produce an oil-renellent finish in textiles. They generally are emulsions or solutions of organic. fluorine compounds such is perfluorinated carboxylic acids, and may contain mod~fiedrcsins (extenders). fl (13) Water-re ellent agents, generally consistin of a ueous emulsions of water-repellent products rsuch as waxes or lanolin) stab1 ~sed y cellulose ethers, gelatin, glue, organic surface-active agents, etc., and containing added soluble salts of, for exam ley aluminium or zirconium. This group of products also includes preparations basecfon silicones and on fluorine derivabves. ?* % (B) Products and preparations used in the paper, paperboard or like industries : (1) Binders used to bind the pigment particles in the coating mixture. They are preparations based on natural products such as casein, starch, starch derivatives, soya protein, animal glue, alginates or cellulose derivatives. (2) Sizin agents or sizing additives used in paper processing to im rove printability, smoo&ess and gloss and to im art writing properhes to the paper. hese preparations may be based on rosin soaps, ortified resins, wax dispersions, paraffin dispersions, acrylic polymers, starch and carboxymethylcellulose or vegetable gum. P P (3) Wet-strengthenin agents. These preparations are used to increase tensile strength, tearing strength, %ursting strength and resistance to abrasion of wet paper or nonwovens. (C) Products and preparations used in the leather or like industries : (1) Binders. Preparations which are intended to anchor the pigment colours in leather. They are specially formulated, generally on a basis of protein substances, natural resins or waxes, etc. (2) Seasons which are specially formulated to be applied as the final surface seal in leather finishing. Their structure and composition is sirmlar to that of the binders of (1) above. (3) Waterproofing a ents.
