There is something quietly meaningful about a pajama set you have worn for years — one that has grown softer with every wash, that you reach for without thinking on the nights when you most need rest. Knowing how to care for luxury sleepwear properly is what makes that relationship possible. The right water temperature, a considered detergent, and a few gentle habits extend the life of high-quality pajamas by years. When sleepwear is made from thoughtfully chosen fabrics like TENCEL™ Modal or washable silk, it is designed to be cared for without anxiety — and a little intention at laundry time is all it takes to keep every wear feeling as indulgent as the first. What we hear most often from customers who've owned their Gisele for five or ten years: they wish they'd bought a second set sooner.
Does water temperature really matter when washing luxury pajamas?
Yes — water temperature is one of the most consequential choices you make at laundry time. Hot water causes protein and cellulosic fibers to swell rapidly, breaking down the fiber structure over repeated cycles and leading to pilling, shrinkage, and a rougher texture (American Association of Textile Chemists and Colorists, 2021). Cold water keeps fibers relaxed and dimensionally stable while still removing body oils, light soiling, and residual fragrance.
For Modal fabrics — including Eberjey's TENCEL™ Modal pajamas — cold or lukewarm water (below 30°C / 86°F) is the ideal range. TENCEL™ Modal is derived from sustainably sourced beechwood pulp processed by Lenzing AG using a closed-loop system that recovers more than 99% of the solvent used in production (Lenzing AG, 2023). That manufacturing integrity means the fiber arrives optimized for longevity — your job is simply not to undermine it with unnecessary heat.
For washable silk, heat denatures the sericin proteins that give silk its luminous drape, which is why warm and hot cycles accelerate dullness and fiber breakdown (Textile Exchange, 2022). Keep the water cool and you preserve both the sheen and the hand feel.
What detergent should I use for Modal and silk pajamas?
The wrong detergent can do more damage in a single wash than months of normal wear. Conventional laundry detergents are formulated for cotton and synthetics and often contain optical brighteners, bleaching agents, and high-pH surfactants that are harsh on delicate natural and semi-synthetic fibers (Good Housekeeping Institute, 2022). For luxury sleepwear, choose a gentle, pH-neutral liquid detergent specifically designed for delicates.
Enzyme-based detergents break down sweat and body oils effectively, but protease enzymes can gradually weaken protein fibers like silk with repeated exposure (Journal of Natural Fibers, 2020). For silk pieces, choose a detergent that lists its enzyme types clearly, or opt for a non-enzyme delicate wash.
One habit worth leaving behind: fabric softener. It works by coating fibers with a waxy residue that over time reduces moisture-wicking properties and creates buildup that makes fabric feel heavy and dulled (American Cleaning Institute, 2021). The beautiful thing about high-quality Modal is that it naturally becomes more supple with every wash — you do not need to add anything to achieve that result.
How should I machine wash my pajamas without damaging them?
For most luxury sleepwear, cold water paired with a gentle or delicates cycle is the safest approach. The gentle cycle reduces mechanical agitation — the physical tumbling action of the drum — which is the primary cause of pilling and fabric fatigue in delicate garments (AATCC, 2021).
Always turn garments inside out before washing — this protects printed or embroidered details and reduces surface abrasion on the outer face of the fabric. A mesh laundry bag minimizes entanglement and friction against drum surfaces and zippers, which is particularly worthwhile for silk pieces where snags are most consequential. Eberjey's Inez Washable Silk pajamas are designed to be machine-washable, but using a mesh bag elevates that convenience into a genuinely protective ritual.
Smaller loads are kinder to delicate garments. Wash your luxury sleepwear together in a small dedicated delicates load rather than including it in a large mixed wash.
Can I put luxury pajamas in the dryer?
The dryer is where most garment longevity is quietly lost. High heat causes fibers to contract and stiffen, accelerates color fading, and — in the case of silk — can permanently alter the surface sheen by denaturing the protein structure (Lenzing AG, 2023).
Air drying is the considered choice for TENCEL™ Modal and silk sleepwear. Lay garments flat on a clean, dry towel or a mesh drying rack, gently reshaping them while still damp. Hanging wet sleepwear can stretch the shoulders and distort the neckline, so flat-drying is preferable. Choose a well-ventilated area away from direct sunlight — UV exposure fades color and weakens fiber integrity over time, particularly in silk.
If air drying is not practical, a tumble dryer on its lowest heat setting — often labeled "air fluff" or "no heat" — is a reasonable option for Modal. For silk, machine drying is not recommended unless the care label explicitly states otherwise.
How do I store luxury sleepwear to protect it between wears?
The single most important principle is to store only clean sleepwear — body oils, sweat, and residual cosmetic products on unwashed garments continue to interact with fiber structure during storage, weakening fabric and setting stains more deeply over time (American Academy of Dermatology, 2020).
For everyday storage, folding Modal pajamas in a drawer works beautifully — the fiber does not wrinkle aggressively. If you prefer to hang sleepwear, use padded or wide-shoulder hangers to distribute weight evenly and avoid stress at the shoulder seams.
For longer-term storage, breathable cotton bags are preferable to plastic. Plastic creates a sealed environment that can trap residual moisture and, for silk in particular, cause yellowing by preventing the fiber from breathing. Cedar sachets repel moths without chemical residue. Store in a cool, dark, dry space away from heat sources, which accelerate fiber degradation.
What should I know about caring for TENCEL™ Modal specifically?
TENCEL™ Modal is a semi-synthetic fiber made from sustainably certified beechwood pulp, processed using Lenzing AG's closed-loop Ecovero process (Lenzing AG, 2023). It carries the OEKO-TEX Standard 100 certification, meaning every component of the fabric has been tested against over 100 harmful substances and confirmed safe for skin contact (OEKO-TEX, 2023). For sleepwear worn directly against skin for hours at a time, this matters deeply.
The fiber absorbs 50% more moisture than conventional cotton, keeping fabric feeling dry and comfortable through the night (Lenzing AG, 2023). It is also colorfast in ways that some natural fibers are not, holding dye consistently through repeated washing — which is why Eberjey customers so often describe their Gisele sets as retaining color and softness after years of regular wear.

How do I care for washable silk differently from Modal?
Silk is a protein fiber — structurally closer to human hair than to plant-based fibers — and this distinction shapes how it needs to be cared for. Where Modal is resilient and grows more supple with washing, silk rewards a slightly more attentive touch. is helpful context for anyone navigating silk care for the first time.
For washable silk like Eberjey's Inez collection, machine washing on a cold, delicate cycle in a mesh bag with a pH-neutral, silk-safe detergent is appropriate. What distinguishes washable silk from conventional dry-clean-only silk is a finishing treatment that improves dimensional stability in water, reducing the risk of shrinkage and distortion (Textile Exchange, 2022). Avoid wringing or twisting the fabric when wet, as silk in a saturated state is more vulnerable to fiber stress.
Flat drying is strongly preferred. Once dry, silk can be lightly pressed on a low-heat iron setting — turn the garment inside out and use a pressing cloth as a buffer to protect the sheen.
How do I know if I'm shortening the life of my pajamas without realizing it?
A few common habits quietly accelerate wear. Overwashing is the first — sleepwear does not need to be laundered after every single wear. Rotating between two or three sets allows each garment recovery time, which meaningfully reduces cumulative fiber stress over a season (Journal of Natural Fibers, 2020).
Overloading the washing machine puts garments under significant mechanical stress. A too-full drum means garments are forced against each other and the drum walls rather than tumbling freely — the cause of most surface abrasion and pilling in otherwise well-cared-for fabrics. Storing damp garments is equally damaging; mildew develops quickly in damp textile environments and can set into fiber in ways that are very difficult to reverse (Good Housekeeping Institute, 2022).
The quality of the fabric you begin with sets the ceiling for how long proper care can extend a garment's life. explores this idea in more depth — because the care habits in this guide are only as meaningful as the fabric they are protecting.
The softer side of life is found in the small rituals: the cool water wash, the flat-dried set waiting at the end of a long day, the pajamas that feel, somehow, even more like a second skin than they did the season before. Care well, and they will last.
