Relevant or not[edit]

One user did not like that I added links to a source that show that hemp hurds was vaste (hemp hurds is the part of the hemp stem that don¨t contain long fiber). Hemp hurds was in 1937 not used by paper mills. Jack Herers theory claim that the newsprint king Hearst had a financial interest in a ban for Hemp. The claim is based on the assumption that "hemp hurds" could become a "threat" for Hearst timber holdings as a raw material for paper.

An article from 1937 give this information:

- Demand for cellulose was increasing FLAX AND HEMP: FROM THE SEED TO THE LOOM, Mechanical Engineering Magazine, February 1937 - Hemp was a possible alternative. but the process making paper from hemp hurds was in 1937 only a vision, not something that paper mills used in the US or Canada. - Other sources show that important improvements were made in how to deink recycled waste paper.US Patent 2077059 A, 1937

Newsprint from recycled paper was a much more realistic alternative than paper from hemp hurds. Paper from the long fibers in hemp had become too expensive. Jack Herers theory about hemp hurds could become a "threat" to Hearst profits has very low credibility. As I see it is relevant to add information that oppose Jack Herers theory about a "treat" from hemp. Dala11a (talk) 16:28, 23 February 2015 (UTC)

Dala11a. Although your information may be factual history, it is more detailed than is necessary for an encyclopedia; see WP:NOT and I have reverted your edits, so WP:CONSENSUS applies. Also, it appears English is not your native language so please practice writing content in your sandbox or post edits first on the Talk page for other editors to determine whether to include the information and edit it. Lastly, please do not edit war, WP:EW. Thanks. --Zefr (talk) 18:58, 23 February 2015 (UTC)
You avoids answering the question of why you think the text is too deeply into the details. Jack Herer sold more that 600 000 books about hemp and many believed himDala11a (talk) 20:17, 23 February 2015 (UTC)
I would say enough text is devoted to Hearst, a speculative discussion anyway as no proof exists about the role he or his businesses played in inhibiting the hemp industry in the 1930s. Secondly, there were too many details about the hemp fibers for a general reader of the encyclopedia. The remaining statements are adequately referenced. --Zefr (talk) 21:01, 23 February 2015 (UTC)
Some of the classic bogus info from Jack Herer is creeping back in. We've dealt with most of that before; see the archives of the talk page, especially at Talk:Hemp/Archive_2#Removed bogus info from hemp sites. John Nagle (talk) 08:08, 24 February 2015 (UTC)

Strength of hemp fiber[edit]

I wanted to revive this discussion. I dont think my question has been answered yet. Thank you. Dracoshempemporium (talk) 00:43, 6 March 2015 (UTC)

Strength of Hemp Fiber

The Fiber section of this article is much too modest. It briefly mentions some uses of the fiber and the economic impact but no mention of the strength or length of the fibers in any way. I was particularly looking for information on the strength of hemp fibers more particularly in comparison to those of cotton. Dracoshempemporium (talk) 22:18, 24 September 2014 (UTC)

   There are some measured values here.[17] Hemp is comparable to flax or linseed. Here are some figures for various bast fibers. Note that you have to convert diameter to area and divide by that to get tensile strength per cross section.[18]. The winner on tensile strength among the bast fibers seems to be sisal, which is the most popular fiber for string and twine. Cotton is not a bast fiber, and the processing is very different, so direct comparison of individual fiber strength is hard. There's both cotton and hemp rope; hemp rope is stronger in the same size, but rots. (It rots from the inside out, so it looks fine until it breaks. (Sailing ships phased hemp rope out starting around 1850 or so, once manila rope came in. In turn, synthetics have taken over most marine applications.) [19].

       Ok. Thanks a bunch for your response! I should have been more specific though. I was attempting to prove or disprove the phrase "Hemp fiber is 10 times stronger than cotton and can be used to make all types of clothing." Well I know it can be used to make any type of clothing that isn't specifically not hemp but I wonder if anyone has ever constructed fibers of equal diameter hemp versus cotton and hung weights from them. Dracoshempemporium (talk) 17:30, 25 September 2014 (UTC)
           What do you mean by "stronger"? Wear resistance? Tensile strength? In general, the bast fibers are stronger than cotton, but not as comfortable to wear. Sisal is stronger than hemp, but while sisal clothing exists, it's not popular. The strength of cotton can be increased; see mercerized cotton. Cotton/polyester blends are much stronger and longer-lasting than pure cotton. For raw tensile strength, there's ballistic nylon and Kevlar. As for the article, we can probably leave out "Hemp fiber is 10 times stronger than cotton and can be used to make all types of clothing", which appears uncited on a number of promotional sites for hemp John Nagle (talk) 21:45, 25 September 2014 (UTC)


Ok thanks again. I meant pure hemp fiber of a given area and exactly the same shape as a control fiber of pure cotton with exactly the same dimensions tested against each other. To specify I mostly meant tensile strength but if there was any raw data out there about wear resistance that would probably help too. Dracoshempemporium (talk) 23:25, 25 September 2014 (UTC)

Woo. That was a doozy of a book you cited. Very informative really. Well is it safe to say that hemp fibers are MANY times stronger than cotton fibers and can be produced with MUCH less water and little to no fertilizer? I think after the part where it reads " Pure hemp has a texture similar to linen." It should include some of this data you have presented or similar indicating the different statistics on strength of hemp fiber. This important information seems lacking from the article. Perhaps sometime I will take the time to edit it in. — Preceding unsigned comment added by Dracoshempemporium (talk • contribs) 21:13, 26 September 2014 (UTC)
