Good DWR Handling Is Very Important.

WL Gore & Associates, a outdoor fabric specialist, has published a new study to provide non fluoride long-lasting water repellent (DWR) treatment, which is more environmentally friendly than the current long-acting water repellent treatment.

In different ways

Processing to evaluate the effectiveness of Gore-Tex jacket has become part of WL Gore's third life cycle assessment (Life Cycle Assessment), which will be chosen DWR in the future.

Guidance.

Gore processes the jacket with different DWR and tests it in different outdoor environments in the most commonly used way in the LCA scenario. Gore says, in fact, the currently available non fluorinated DWR treatment has obvious disadvantages: it will no longer provide effective waterproofing after a short period of use.

It is pointed out that for many consumers, it is not desirable to accept the loss of waterproofing and lead to disappointment and premature replacement of coats.

Changing the coat frequently has a negative impact on the environment, because every production of a new jacket consumes other resources such as chemicals, energy and water.

This study shows that non fluoride DWR treatment has low water repellent efficiency and is the single driving force that the jacket has the greatest impact on the environment.

WL Gore said that compared with the company's current short chain polymer DWR, backpackers must wash their garments more frequently and repeat DWR processing if they want to maintain a satisfactory level of waterproofing.

"Good DWR handling is very important, which can prevent the coat from being soaked in water, because the body's moisture will increase weight and discomfort, and may cause the individual's concentration and physical ability to decrease."

Waste heat recovery system: the waste heat recovery technology of dyeing wastewater, air compressor waste heat and condensed water is the most advanced, most reasonable and environmentally-friendly heat recovery system.

The waste heat recovery system is suitable for all textile printing and dyeing factories. It can recover more than 90% of the heat energy, not only reduce heat pollution, but also recover most of the available heat.

To provide low-cost, clean, environmentally friendly and renewable energy supply for factories.

Heat insulation technology of dye vats: the most comfortable and advanced protection method of dye jar is: the super thin thermal insulation coating is used for heat preservation of the dye cylinder, reflecting the heat in the cylinder, forming repeated self radiation, increasing the utilization efficiency of heat, and lowering the exterior temperature of the dyeing cylinder, not scalding the workers, so as to ensure the safety and stability of production.

The recycling system of cloth washing wastewater: the waste water collected from the washing workshop is filtered through the water-saving filter to ensure that more than 98% of the impurities in the water are filtered, automatic slag removal, automatic filtration, automatic cleaning, and no need for manual cleaning.

The utility model can achieve more than 90% backwater utilization rate and greatly reduce the water consumption of the washing workshop.

Rapid cooling system: rapid cooling system of 24 hours all weather, can reduce the circulation of the circulating cooling water rapidly, save a lot of cooling time and water consumption, form a closed circulation water cooling system, can replace the cooling tower, not only save time, save water, and greatly improve production efficiency.

The circulating water can be rapidly reduced to normal temperature.
