Relaxation Shrinkage and Hygral Expansion (SiroFAST-4): Mill Questions for Suit Cloth

Quick answer: Shi Yuan Suit Factory treats relaxation shrinkage and hygral expansion as mill test results to request before cloth lock—not a factory test listed on acumenwear.com. The order path: the shop asks the mill for dimensional-stability data, Shi Yuan records the cloth on the brief, and the 7–14-day sample shows how the cloth makes up and presses. 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 reference, any SiroFAST data the mill supplies, and MTM from 1 or bulk from 50 on WhatsApp +65 8013 8838.

Which dimensional-stability results should a shop ask the mill for?

A shop should ask the mill whether the cloth has relaxation shrinkage and hygral expansion results and what the mill concluded from them, before locking cloth. Shi Yuan Suit Factory cuts the shop-approved cloth, MTM from 1 or bulk from 50, and runs no objective-measurement lab for the shop.

Shi Yuan Suit Factory (Est. 2009) reads dimensional stability as mill test data settled before the sample clock. The Woolwise presentation Optimising fabric quality through fabric objective measurement states that the SiroFAST-4 Dimensional Stability Test measures both components of the dimensional stability of wool, relaxation shrinkage and hygral expansion, that the test predicts shrinkage in garment making and panel distortion in humid atmospheres, and that the separate Sirolan PressTest measures the angle a 180-degree fold adopts after pressing. A shop therefore asks the mill for these results before bulk from 50; pre-shrinking sits on the separate London-shrunk post.

What are Shi Yuan's two order tracks?

  • MTM — from 1 piece: one client cloth at a time; the shop judges make-up on a single suit.
  • Bulk — from 50 per style: one style in a size run on the same cloth reference after the sample is approved.

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. Mill stability answers should arrive before the cloth is locked for production.
