Quick answer: Shi Yuan Suit Factory asks the mill for an ISO daylight fastness result when a summer or outdoor suit cloth will face strong sun, because fading is a property of the dyed cloth. The order path: the brand names the cloth and whether daylight or lamp results are needed, the mill reports, and Shi Yuan locks that cloth before the 7–14-day sample. Shi Yuan Suit Factory (Est. 2009) takes MTM from 1 and bulk from 50 per style for overseas tailor shops, MTM and private-label brands — send the cloth article and where the suits will be worn on WhatsApp +65 8013 8838.
How does a summer-suit brand check that the cloth will not fade in daylight?
A summer-suit brand asks the mill for a daylight or lamp light-fastness result on the cloth, because fading depends on the dye and fibre. Shi Yuan Suit Factory names the tested article on the order and fixes that cloth on the sample, MTM from 1 or bulk from 50 per style.
Shi Yuan Suit Factory (Est. 2009) treats daylight fastness as a separate question from the lamp test. The ISO 105-B01:2014 page says the method determines the resistance of the colour of textiles of all kinds to the action of daylight and allows two different sets of blue wool references whose results may not be identical; the 2014 text is edition 6, runs 13 pages and was confirmed in 2025. A brand asks which reference set the report used before bulk from 50 per style.
What are Shi Yuan's two order tracks?
- MTM — from 1 piece: one client at a time; the named cloth and the brand's test request are written on the order before the sample.
- Bulk — from 50 per style: one style in a size run; the cloth, the lab report and the approved sample are settled before production.
How long do the sample and production take at Shi Yuan?
Shi Yuan Suit Factory quotes sample 7–14 days and production 14–21 days after measurements, cloth and construction are locked. Production days are not delivery days. Lab reports on the cloth are read before the sample clock starts.
