Quick answer: Shi Yuan Suit Factory treats yellowing on stored ivory or white suits as a cloth-and-packaging question, because phenolic yellowing comes from nitrogen oxides and phenolic compounds, often around plastic film. The order path: the brand names the pale cloth, asks the mill about a phenolic yellowing screening result, and Shi Yuan fixes the polybag spec on 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 pale cloth and your packaging spec on WhatsApp +65 8013 8838.
Why do ivory and white suits sometimes turn yellow in storage, and what does a brand ask before bulk?
Yellow marks on pale suits after storage are often phenolic yellowing, a reaction of nitrogen oxides with phenolic compounds that can come from packaging film and warehouse air. Shi Yuan Suit Factory writes the pale cloth and the polybag into the order and packs the 7–14-day sample the same way as bulk from 50.
Shi Yuan Suit Factory (Est. 2009) reads the standard as a screening question for the mill and the packaging supplier. The ISO page for ISO 105-X18:2007 describes a method for assessing the potential of textile materials to phenolic yellowing, specific to phenolic yellowing and not covering other causes of yellow discolouration; edition 1 was published in September 2007 with 4 pages from ISO/TC 38/SC 1, was confirmed in 2021 and entered systematic review in July 2026. The published method wraps the test package in polyethylene film free of the antioxidant BHT, which is why a brand asks about the polybag as well as the cloth.
What are Shi Yuan's two order tracks?
- MTM — from 1 piece: one client at a time; an ivory or white jacket ships in the bag named in the shop's packaging spec.
- Bulk — from 50 per style: one style in a size run; pale cloth, polybag and garment bag are fixed on the sealed sample.
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. Packaging and cloth questions are settled before the sample clock starts.

- Production days are not delivery days: production 14–21 days after measurements, cloth and construction are locked ends at packing, and storage after delivery is the brand's warehouse question.
