Preparing your fabric: This fabric is delivered cut & sew ready, pre-washing is neither recommended nor required. If you must pre-wash your yardage, use a gentle cycle and hang dry to avoid wringing damage.

Fabric sticking: This is a common problem with plasticized fabrics like PUL. It's best to use a Teflon foot, these are available at sewing stores for between $3 and $10 for most machines. If you can't get a teflon foot, you can try sewing through wax paper or daubing a tiny amount of sewing machine oil on your presser foot.

Leaking after sewing: Make sure you use good quality polyester thread. Tex-27 or 65/2 grades are the best. Cotton or rayon threads should not be used in diapers as they naturally wick moisture. Also make sure you use BALL POINT NEEDLES! Remember, PUL is a knit, so like all knits use a ballpoint needle. Sharps (the kind you use for wovens and felts) will slice the yarns which will cause the holes around the threads to enlarge and leak.

Need PUL for binding: You can make your own binding from PUL knits (instead of using FOE). Cut strips across the grain if you desire some stretch, and with the grain if you want to limit stretch. PUL is a knit base so you DO NOT cut it on the bias.

Washing Instructions: It is recommended to use a zero residue detergent - liquid detergent preferably. Wash temperatures can be hot, between 145 and 165 degree F (65 to 75 degree C).
DO NOT use bleach. If required non chlorine oxygenated bleach can be used sparingly, provided the detergent should not already contain sodium percarbonate (the active ingredient in many oxygenated bleaches). The detergent must also not contain any Fabric softeners, Natural oils, Perfumes, Dyes, UV brighteners, Stain guard ingredients, Enzymes.
DO NOT add washing soda, soda ash or soda crystals to the detergent. The use of vinegar and/or baking soda can together or individually cause delamination.

Rinsing Instructions: It is highly recommended to add an extra rinse cycle since even minute traces of detergent or other washing chemicals which may not have been washed out from the diaper/product made from the PUL are highly detrimental to the film and reduce the life of the laminate.

Drying Instructions: Dry on medium heat, at a temperature not more than 130 degree F (50 degree C). Use of drying sheet with fabric softeners is not recommended. DO NOT wring or iron on the film side. Any urethane film is affected by bleach, chlorine and dry heat exceeding 130 degree F.
Exposure to sunlight affects the urethane film. The film will turn yellow and crack over time. When the UV index is high this can happen in as little as 10 hours.
