Monforts, a German textile machinery company, has announced that at 2nd Kingpins24 virtual denim show broadcasted on June 23-24, sustainable benefits of hemp fibre were referenced by many of its customers who are now including it in their collections, including AGI Denim, Artistic Milliners, Black Peony, Calik, Cone Denim, Naveena Denim Mills (NDM) and Orta.
“Hemp is an easy to grow fibre which requires no irrigation, no fertilisers, no herbicides and no chemicals,” Allan Little, director of product development for cone denim, which has recently launched its Sweet Leaf collection featuring the fibre, said in a press release.
Significantly, it also uses fifty per cent or even less water than cotton in cultivation.”
“It can also bring some new aesthetics to denim too,” Little said.
“Hemp has a unique colour and adds a different cast to our indigo, the drape and texture of the fabrics is different and it even adds a bit of a unique hand, so combined with its sustainable credentials we are proud to be bringing the Sweet Leaf collection to the market.”
Cone is currently sourcing its hemp from France, but with much of its manufacturing now in Mexico and with the introduction of the US Farm Bill in 2018 which has legalised the growing of legal hemp is exploring the possibility of investing in the US supply chain.
“With US hemp we’re really at the R&D phase,” Little further added. “It’s a unique crop, so coming up with the right stalk to provide the right fibre is challenging. We’ve experimented with different types of seed and various methods of decortication.”
Decortication, Little explained, is the mechanical removal of the outside layer of the hemp stalk to useable fibre on the inside. A second process, cottonisation, is necessary to make the fibre suitable for spinning, because compared to cotton, hemp is longer, stiffer, and less flexible.
At the end of 2019, Naveena (NDM), headquartered in Karachi, introduced fabrics featuring up to 51 per cent hemp content in blends with Tencel and recycled polyester and this year has developed the first 100 per cent hemp denims.
“The response to the fabrics we showed last year was incredible and we were looking forward to the response to this latest development which everyone was asking for at the Kingpins show in Amsterdam, which unfortunately was unable to go ahead,” NDM’s director of marketing, Rashid Iqbal, said in the release.
We produced initial samples in an undyed state because we were not sure how the wet spun yarn would react in the dyeing, but I’m happy to say we have had success in this respect and are now able to provide one hundred per cent indigo dyed hemp denim.”
“Differentiation is the key in the highly-competitive denim industry and we have assisted our customers with trials and optimised processing parameters for a range of different fibres, including hemp, both at our Advanced Technology Centre in Germany and at their own mills around the world,” Hans Wroblowski, Monforts head of Denim, said.
Monforts has a dominant position in the field of denim finishing with its well proven Montex stenters.
The latest Monforts innovation for denim is the CYD yarn dyeing system. This technology is based on the effective and established dyeing process for denim fabrics that is now being applied for yarn dyeing.
The CYD system also integrates new functions and processes into the weaving preparation processes spinning, direct beaming, warping and assembly beaming, followed by sizing and dyeing to increase quality, flexibility, economic viability and productivity. A full CYD line is now available for trials at the company’s Advanced Technology Centre.
