Cost Breakdown of Disposable Soft Cotton Underwear: Where Does the Money Go?
disposable soft cotton underwear Fabric – The Biggest Cost
Fabric accounts for 50% to 70% of the total cost. The three mainstream materials differ in price by several times:
Non woven (SMS or thermal bonded) : The cheapest – cost a few cents. Breathability is acceptable, but it feels stiff when worn for a long time. Not suitable for all day wear.
Cotton knitted fabric : The same material used in regular underwear – soft, skin friendly, and absorbent. It costs 3 to 5 times more than non woven. Suitable for postpartum care, nursing homes, and overnight business trips.
Bamboo fiber / TENCEL™ : Cost falls between the two. Bamboo fiber is naturally antibacterial and wicks moisture quickly – good for tropical climates or people who sweat a lot. It is biodegradable, and eco conscious buyers are willing to pay more.
Fabric weight also affects cost. For the same cotton material, 160gsm is about 15% more expensive than 130gsm, but it is thicker, more durable, and not see through. When sourcing, always ask for the “grams per square meter” – just knowing it is “cotton” is not enough.
■ Packaging – The Second Largest Item, Often Overlooked
Individual wrapping is not over packaging – it is a necessity. Each piece of underwear is heat sealed in a food grade PE pouch and only opened when used. Individual wrapping adds about $0.007-0.014 per piece. Simple packaging (several pieces in one large bag) costs almost nothing, but the risks are high: after opening, the remaining underwear is exposed to air, absorbs moisture, collects dust, and grows bacteria. For orders exported to the EU, Japan, and Australia, individual wrapping is mandatory. Saving those few cents could cost you a full container of returns.
Labor and Testing – Invisible but Unavoidable
Sewing, quality inspection, folding, bagging, and boxing – every step has a labor cost. Highly automated factories have lower labor costs; semi automated factories have higher labor costs. Testing includes seam strength (dry and wet), elastic recovery of the waistband, seal integrity of the individual pouch, and microbiological indicators. If you skip these tests, you save money, but customer complaints will catch up with you.
