Definitions

• This invention relates to improvements in the manufacture of cordage of all kinds, including ropes, cords, twines and lines, and whilst it is more particularly applicable to cordage made 5 from sisal, it is also applicable to cordage made from other varieties of hemp, jute, cotton and coir and other vegetable fibres, and has for its objects increasing the strength, flexibility and durability of cordage manufactured from such vegetable fibres.
• heavy cordage i. e.
• Sisal enjoys certain advantages as a material for cordage, but has the drawback, in cords and twines, of not being particularly flexible or pliable, and when employed for ropes has the almost inseparable disadvantage of absorbing so great a (11131117 tity of water when immersed therein as to very 30 considerably increase its diameter with a natural increase in weight.
• the present invention comprises the treatment of cordage after manufacture or the treatment of the fibres or strands before or during manufacture with sulphonated oilpreferably an electrically ionized sulphonated oilor an aqueous solution thereof with or without the addition of wax, resin or other waterproofing material and/or a fireproofing material.
• sulphonated oil preferably an electrically ionized sulphonated oilor an aqueous solution thereof with or without the addition of wax, resin or other waterproofing material and/or a fireproofing material.
• the vegetable fibres during homeling or batching are sprinkled with an aqueous solution of a sulphonated oil-preferably an electrically ionized sulphonated oilin admixture with a wax, such as carnauba or japan wax.

• the yarn is then spun, the strands are formed and are laid into ropes in the known manner.
• the cordage is formed in the first described method of carrying this invention into practice, for example, about 15 parts of a vegetable wax, such as carnauba or japan wax, or a mixture of waxes are dissolved in about '75 parts of sulphonated oil-preferably 5 neutralized sulphonated oil or oils treated to an electric ionization process as described in patent specification No. 1,913,202, and having a pH value of not less than 7 when diluted with 10 times its volume of water-the wax and oil is then intimately mixed with from 350 to 500 parts of water and the resultant solution is used for sprinkling the fibres before being spun into yarn.

• sisal cordage treated according, to this invention materially increases in diameter, which it retains in use without impairing its original strength, does not absorb water when immersed therein, and is rendered 35 extremely flexible or pliable as compared with untreated cordage of a corresponding diameter and strength.
