When it comes to airing our dirty laundry, we wonder why the laundry services we pay for always do a better job than we can at home. With the help of "professional" washing machines, laundry services simply do a cleaner job. Professional laundry services count on front-loading
washers to impress the customers, while most Taiwanese households still stick with the conventional top-loading washers to get the dirty job done.
In the past, front-loading washers in Taiwan were so prohibitively expensive that only professional cleaners or laundromats could afford them. In recent years, to satisfy Asian customers, washing-machine manufacturers have been doing their best to develop inexpensive front-loaders that can still get clothes cleaner, save more water and electricity and use less detergent than top-loaders.
Moreover, the trendy aspect of nano-technology used in the latest washers is sure to please tech-savvy users.
More importantly, the overall price of a front-loader has now plunged to somewhere between NT$25,000 and NT$30,000, depending on loading capacity.

Taipei times: What is the front-loading washing machine?
Huang Shih-liang: This type of efficient washing machine has a door in the front instead of an opening on top of the machine. Clothes are placed in a horizontally-oriented stainless-steel drum instead of a conventional tub with central agitator.
TT: In terms of the operation, what is the difference between the the top-loading washer and the front-loading washer?
HSL: The top-loading washer is built on a vertical axis and uses more water to fully immerse clothes in the tub and scrub them clean with agitation. The front-loading washing machine, however, is built on a horizontal-axis and does not have an agitator that is used in a top-loading vertical-axis washing machine. With a more advanced structure, the front-loader generally uses less water, electricity and detergent.
TT: Why does the front-loading washing machine use less water and save more money?
HSL: A front-loader with the loading capacity of up to 10kg will consume 70 liters to100l of water in one load of laundry. Meanwhile, a top-loader with the same capacity will take 180l to 240l liters of water. Clearly a front-loader reduces water consumption by at least half and the amount of detergent used is also reduced in the process.
TT: If equipped with the same loading capacity, why does the tumble of the front-loader look smaller than that of the top-loader?
HSL: In a front-loader, the clothes are lifted and dropped into a more concentrated solution of water and detergent. The reversing tumble action kneads the water and detergent deeply into the fabric fibers. Since the washer never fills above the bottom of the washer door, much less water is used and less space is needed.
TT: Some front-loaders use warm water and nano-technology to do the laundry. Why do they do this?
HSL: Some front-loaders can automatically heat water up to 40?C to 60?C, which further reduces detergent use and helps tackle smelly clothing. Some manufacturers have even incorporated what they call "silver nano-technology" to enhance the anti-bacteria function. This is even more effective than the use of warm water for washing.
TT: What else do we have to keep in mind while using a front-loader?
HSL: First, the front-loader usually uses the foam produced by the detergent to gauge the cleaning process. Putting excessive detergent in the wash may cause front-loaders to wash clothing for excessive periods of time.
Second, as elderly or people with restricted movement sometimes find it difficult to bend to fill front-loaders, new designs are now emerging in which the performance advantages of front-loaders are coupled with the convenience of a top-loading design.

Jason Han says that the e-arrival card spat between South Korea and Taiwan shows that Seoul is signaling adherence to its “one-China” policy, while Taiwan’s response reflects a reciprocal approach. “Attempts to alter the diplomatic status quo often lead to tit-for-tat responses,” the analyst on international affairs tells the Taipei Times, adding that Taiwan may become more cautious in its dealings with South Korea going forward. Taipei has called on Seoul to correct its electronic entry system, which currently lists Taiwan as “China (Taiwan),” warning that reciprocal measures may follow if the wording is not changed before March 31. As of yesterday,
The Portuguese never established a presence on Taiwan, but they must have traded with the indigenous people because later traders reported that the locals referred to parts of deer using Portuguese words. What goods might the Portuguese have offered their indigenous trade partners? Among them must have been slaves, for the Portuguese dealt slaves across Asia. Though we often speak of “Portuguese” ships, imagining them as picturesque vessels manned by pointy-bearded Iberians, in Asia Portuguese shipping between local destinations was crewed by Asian seamen, with a handful of white or Eurasian officers. “Even the great carracks of 1,000-2,000 tons which plied
It’s only half the size of its more famous counterpart in Taipei, but the Botanical Garden of the National Museum of Nature Science (NMNS, 國立自然科學博物館植物園) is surely one of urban Taiwan’s most inviting green spaces. Covering 4.5 hectares immediately northeast of the government-run museum in Taichung’s North District (北區), the garden features more than 700 plant species, many of which are labeled in Chinese but not in English. Since its establishment in 1999, the site’s managers have done their best to replicate a number of native ecosystems, dividing the site into eight areas. The name of the Coral Atoll Zone might
Nuclear power is getting a second look in Southeast Asia as countries prepare to meet surging energy demand as they vie for artificial intelligence-focused data centers. Several Southeast Asian nations are reviving mothballed nuclear plans and setting ambitious targets and nearly half of the region could, if they pursue those goals, have nuclear energy in the 2030s. Even countries without current plans have signaled their interest. Southeast Asia has never produced a single watt of nuclear energy, despite long-held atomic ambitions. But that may soon change as pressure mounts to reduce emissions that contribute to climate change, while meeting growing power needs. The
