Green Farmers. The hemp and linen is grown without the use of herbicides, pesticides or synthetic fertilizers. The fibers we use in the yarn are “tow” or extremely long fiber strands.

Exceptional Standards. The fabric is softened, bleached and/or dyed at our Italian dye house, which is one of relatively few houses in the world that is qualified to produce a dyed or finished fabric which can be a certified “organic textile.”  Being an “organic textile," means not just that a fabric uses organic fibers in the yarn, but that every step of the production process has been certified eco-friendly. 

For those who are interested, our dye house has received the Italian Institute for Ethical and Environmental Certification (ICEA) for adherence to AIAB (Italian Association for Biological Agriculture) standards, which currently (summer 2008) are the most stringent in the world.

Safe, Low-Impact Dyes. We invested more than two years of research in our dyes in order to achieve color consistency, colorfastness and complete absence of toxicity. The dyes meet EU and Global Organic Textile Standards to be free of AZO colorants (a cancer causing toxin that is used in many dyes), heavy metals and aromatic amines and the dyestuffs are completely biodegradable (except for some of the blues which can contain copper).

Old-World Methods. The yarns are woven into the fabric at a mill in southern Italy that has been in the same location for over 100 years. This mill uses absolutely no sizers or de-sizers, in fact it uses no chemicals at all throughout their production process, avoiding chemical baths that degrade the yarn's quality and inherent strength.

Test Results. Lopez is predicted to meet GreenGuard standards. It was tested by an ISO 9001:2000 registered IAQ (Indoor Air Quality) testing lab, which measured the out-gassing of nasty chemicals. Our results were very impressive, well below limits set by the USGBC to allow fabrics to accrue LEED points for low emitting materials.

This test, a combination of gas chromatograph/mass spectrometry and high performance liquid chromatography, lasts for 24 hours. A small piece of fabric is placed in a closed chamber. The chemicals out-gassed for the first 24 hours at a given temperature and pressure are extrapolated to predict the results for the equivalent of a room volume. Based on decay rates for various chemicals, the test predicts the results after 168 hours (the GreenGuard requirement).  So based on those parameters, and the results you see below, our fabrics passed with flying colors.
