Bondage Rope Safety

At first we acted on trust when buying our rope. Simply asking the question if the rope was free from JBO and other chemical substances. The answer was usually positive. So we bought quite some rope from various suppliers. As mentioned in a previous post, some rope wasn’t as clean as said and diving deeper into the stories behind the rope, visually analysing it, we saw that a strong commercial drive, was influencing true customer information. Most information was not even available to the sellers as a lot of the rope came through 3rd and 4th tier value chains. So how to buy safe rope?

We decided that we needed another approach if we really wanted to tackle bondage rope safety. We actually needed to control the whole value chain and build evidence so we could tell the real story. Sourcing, quality control, production sampling and machine settings should be controllable and solid lab-testing should provide the data for building our case. Below you can find the results of our process with our new Premiun Grade Golden Tossa which is expected to be available to our customers from January 2018.

TESTING OUR PREMIUM GRADE GOLDEN TOSSA

Our goal was to produce the ultimate grade of Tossa yarn: High Grade-Clean Batch (HG-CB); Grade 1, without Jute Batching Oil (JBO), coated using an appropriate bio-friendly agent to reduce hairiness. Safe rope in the making.

JBO is used extensively in jute yarn production due to cost-efficiencies. Hydrocarbons contained within the C15 to C20 range have been widely researched, conclusively confirming carcinogenic toxicology dangers.

Our 100% corchorus olitorius Tossa jute yarn has been specified from the seeds and the soil, through growing, (using GMO-free propagation agents and bio-fertilizer mulch), cutting, retting, sorting, piling and carding, drawing and spinning, and batching processes. We take great care to avoid JBO mineral oil and other contaminations at all stages.

The Tossa jute is grown from the JRO-524 (Navin) variety, evolved as a cross-pollination between Sudan Green and JRO-632 at the Central Research Institute for Jute and Allied Fibres in 1977. The plant stem is full green, pods are non-shattering and resistant to premature flowering. Ideal for early sowing, JRO-524 is the least susceptible variety to yellow mite and root rot disease in high rainfall areas, and therefore a better alternative to all other olitorius varieties. JRO-524 high yields, and fibre extraction in this variety is easier, generating less chance of filament damage.

Grade 1 Tossa is specified as uniform golden to reddish of the finest structure, minimum filament length 1.5 metres, very strong and with very good lustre, completely free of defects and blemishes; no breaks, dark bark, waste, specks, cuttings or habijabi tangles.

Because of the variety’s hardiness to insect damage and root rot disease, anti-mosquito insecticides and fungicides have not been required, and bio-insecticides reduced to 0.0010% (eg. Our White jute = 0.0253%).

The Tossa jute yarn is batched/spun on dedicated machinery using segregated oil and coating medium feed lines with 3-4% cholesterol free vitamin A and D, and omega 3, 6 component fortified 100% GMO-free soybean oil from seeds grown under a UNICEF social project scheme and with help from UNESCO.

The oil has a specific gravity of 0.9225 ±0.0025 and is completely odourless, clear; very pale yellow. Since first use as a yarn batching medium in 1996, no rancidification has been observed by the lab, or reported by customers.

The 14lb Jute Count, single-ply yarn is coated with a ~2% 9:50 tapioca starch-water spray to reduce hairiness and wound at the @3.6tpi optimum twist for longitudinal cohesion (eg. using for manufacturing rope).

Screening of the hexane extract in the Premium Tossa jute yarn confirms no traces (0.000%) of hydrocarbons consistent with JBO.

None represent any potential negative effects, and the product is therefore considered 100% biodegradeable; environmentally friendly and sustainable, and Food Grade.
