This order follows the start-up of the newly installed, complete high-speed ANDRITZ spunlace line at the Telangana plant.

BTMA member Sellers Textile Engineers is marking its 110th anniversary this year with the introduction of a new concept in carpet shearing, as the essential final step in ensuring tuft uniformity and ‘just new’ freshness in finished carpet rolls.

The company has for many years offered two options in the construction of its shearing cylinders – the first, namely the ‘strap-on’, incorporates spiral blades bolted to the cylinder body and the second, known as the ‘caulked-in’, includes spirals which are fixed very securely in a machined groove within the machine.

The new Sellers’ Hybrid Shearing Cylinder combines the benefits of both, resulting in an improved cut and finer finish, in addition to longer repeatable finishing and increased rigidity.

“The Hybrid Shearing Cylinder has all the advantages of the ‘strap-on’ spiral blade to provide a sharper and cleaner cut, along with enhanced rigidity which significantly lengthens the intervals between the necessary regrinding of the blade,” explains Sellers Director Neil Miller. “We currently have six Hybrid Shearing Cylinders operating in the field and the earliest, which has been installed in both No1 Head position, where the majority of the shearing operation and heaviest cut is performed, and also in No3 Head, where the sharper cutting angle has resulted in a much improved surface quality.”

Sellers shearing machines have led the field in carpet finishing for many decades, enabling the leading manufacturers to stay competitive by enabling the highest quality of finish to be achieved economically and efficiently.

The latest advanced features of these machines include a load cell tension control drive system, an automated touchscreen for easy operator control and fault diagnosis, an enhanced cleaning system including cylinder and blade separation and fully controllable pivoting beds. Further options include thickness monitoring, seam detection and metal detection systems.

“The Hybrid Shearing Cylinder will become standard on our latest machines and also be made available for retrofitting, to provide significant benefits to our existing users,” says Miller. “All of our equipment is designed, manufactured, assembled and tested at our plant in the UK, and as one of the few remaining European engineering companies to make all of our components in-house – with now over a century of accumulated know-how – flexibility in design allows our finishing solutions to be targeted to specific customers and their product requirements. Aligned to this is a lead in process control systems which ensure the accurate control, reliability and repeatability of the processing parameters on all of our machines.”

Sellers remains committed to providing complete finishing solutions for all carpet, tile and artificial grass products. Its range includes machines for tufted secondary backing, both conventional, powder and extrusion lamination, Wilton and Axminster products, artificial grass and foam lines, coating lines for bitumen, PVC, PU and other polymers, as well as shearing for all carpet products.

Ongoing developments on the company’s coating and drying lines have resulted in improved guiding and product tension control as well as dryer efficiency, reducing heat loss and optimising energy use. These include a re-design of the fan pressure boxes and impingement nozzles to increase airflow efficiency, modulating gas burners and introducing easy clean, accessible filters.

In addition, the proven dual zone system has been enhanced, giving a temperature differential of up to 80°C between top and bottom zones. Dryers can be heated by either gas or steam and operation and access have been simplified with controls via touchscreen and PLC.

An extensive range of ancillary equipment is available to provide maximum flexibility to cover product requirements, for both new processing lines and as upgrades to existing equipment.

“Carpet manufacturing is now based on well-established, tried and trusted processes and it’s rare for new innovations to be introduced into this sector,” says Jason Kent, CEO of the British Textile Machinery Association. “The new Sellers Hybrid Shearing Cylinder can provide a competitive edge for manufacturers which is currently being proven in the field. It’s one of a number of new innovations the company is planning to showcase at next year’s ITMA exhibition in Milan.”

HEATHCOAT FABRICS partnered again with BRÜCKNER Textile Technologies and their sales partner ADVANCED DYEING SOLUTIONS to install a finishing line for industrial textiles. HEATHCOAT FABRICS specializes in the production of technical textiles in the fields of texturising, weaving and warp knitting as well as dyeing and finishing. The prroducts are manufactured for use in the automotive, healthcare, defence, and aerospace industries

Mrs. Regina Brückner, CEO and owner of the BRÜCKNER Group stated: "To meet the complex re-quirements of HEATHCOAT is not easy because of the great variety of technical textiles produced. Our line has to finish light as well as heavy articles, so the design, control and the whole line layout have to be flexible, functional and still easy to operate. Fortunately, the team at HEATHCOAT FABRICS is very innovative and open-minded, and together we worked hard to develop the right technology and han-dling. We are very happy that we could convince this customer, whom we appreciate very much, with the productivity of our line and of course with our technological know-how."

The direct gas heated BRÜCKNER POWER-FRAME stenter with its staggered heating source arrangement every half zone provides best available temperature consistency across the length and the width of the stenter. The unit is equipped with a low-lub, horizontally returning combined pin / clip chain and several fabric paths, especially designed for the different fabrics being processed. Together with HEATHCOAT FABRICS technologists, the BRÜCKNER design team developed a special delivery end of the stenter with different edge trimming and slitting possibilities. Depending on the kind of products, the fabrics can be batched on large diameter A-frames, wound on cardboard tubes or plaited into trolleys.

Baldwin Technology Co. Inc. and Fi-Tech Inc. join partnership to ensure service amid growing demand for sustainable solutions. Fi-Tech Inc. will represent Baldwin Technology Co. Inc.’s complete textile and nonwoven product lines as its sales agent in the U.S. and Canada.

Founded in 1972 and headquartered in Richmond, Virginia, Fi-Tech is an agency and distribution firm for textile and non-woven machinery. Its initial focus was on synthetic fibers and nonwovens and it has since expanded its portfolio to represent manufacturers of complete machines or technical components used in the production of nonwovens, synthetic fibers, polymer, textiles, converting, perforated products and tobacco processing. Fi-Tech also maintains a spare parts inventory for many of the companies it represents.

“With the increasing demand of Baldwin’s finishing technology, we needed to find the right partner for sales promotion in the U.S. and Canadian markets for knits, wovens and non-wovens,” said Rick Stanford, Baldwin Technology’s VP Global Business Development, Textiles. “Fi-Tech of Richmond, Virginia is the perfect partner. They are well established in the textile and non-wovens industry and their portfolio of principals provides excellent synergy with Baldwin’s precision spray and plasma treater systems.”

Baldwin’s solutions are used in a wide variety of fabrics from basic jersey and fleece with softening and anti-microbial finishes to technical fabrics such as outdoor gear, military, upholstery, automotive and industrial fabrics utilizing the latest in technical finishes such as DWR, soil release, flame retardants and insect repellent among others.

Monforts has installed and commissioned a new Montex finishing range at the Baltic Works of Halley Stevensons in Dundee, Scotland, to further boost the weatherproofing specialist’s highly flexible operations.

The range, with a working width of two metres, was built at the Montex assembly plant in Austria and consists of a Montex®Coat coating unit in knife execution for paste and foam coating and a Montex 8500 6F stenter.

Founded in 1864, Halley Stevensons has amassed unique technical know-how and manufacturing experience in the art of waxed cotton for weatherproofed fabrics and is able to provide international orders in custom colours and finishes to very low minimum quantities where required. The company exports worldwide and its premium brand customers include Belstaff, Barbours, Filson and J.Crew.

The range has replaced one of the company’s older stenter/coating lines and has already enabled Halley Stevensons to recreate various products with lower coating applications at higher speeds than was previously possible.

Waxed cotton was originally developed by sailors in the early 15th century when Scottish North Sea herring fleets began treating flax sailcloth with fish oils and grease in an attempt to waterproof their sails. Remnants of these sails were used by the sailors as capes to withstand the high winds and sea spray.

By the mid 1850s, sailcloth was being treated with linseed oil, but while initially highly effective, it would yellow and stiffen through weathering over time and eventually lose its waterproofing qualities.

In the years that followed, various treatments were applied to cottons in an attempt to find the most effective weatherproofing solution, and the combination of densely-woven cotton impregnated with a paraffin waxed coating proved most successful. For over 150 years, Halley Stevensons created many different variations of both woven constructions and finishing treatments and now supplies thousands of metres of waxed cotton every year, with each roll produced to custom specifications.

“The beauty of waxed cotton is its durability and longevity,” says Managing Director James Campbell. “The fabrics are breathable, with the wax adjusting to ambient temperatures to be softer and more breathable in warm weather and stiffer and more wind proof in cold conditions.”
While traditional waxes are petroleum or paraffin based, Halley Stevensons has always been comfortable about using a waste product from industry and reusing it to make products that last a lifetime.  

“We are always exploring different finishing techniques and one of our most popular finishes is our hybrid aero – an emulsified blend of waxes,” Campbell says. “This fabric is water repellent but has little wax in the mixture so the handle is much drier to touch than the traditional wet waxes.”

The company has also recently launched a new 100% plant-based wax – Ever Wax Olive – consisting of a blend of olive oil, rape seed and castor bean with comparable water repellence to petroleum and a far better rating than other natural waxes which have come before it.

“The high tradition of skills and fabric innovation imposed by our original guildsmen is still our benchmark standard of honest workmanship today,” Managing Director James Campbell concludes “We use responsibly sourced cotton fabrics and processes that are gentle to the product and low impact to the environment. Our dyeing methods use very low levels of water and our waxes are simply heated up for application and cooled down to store when not in use, meaning no waste discharges. Now, with this new Monforts line, we are also achieving running speeds two-to-three times faster than with the older stenter, combined with less gas usage. It’s proved a great partnership.”

A new fabric inspection technique for accurately detecting the most subtle of defects on patterned fabrics during high speed production has been developed by BTMA member Shelton Vision, of Leicester, UK.

The patent-pending system has been integrated into the company’s WebSpector platform and validated through factory trials on a purpose-built full scale in-house demonstration system with sophisticated fabric transport capabilities. As a result, a first system has already been ordered by a manufacturer of both plain and patterned fabrics, including camouflage, in Colombia. This follows the successful conclusion of a 21-month Innovate UK project in which techniques for the resolution of complex pattern deformations were developed by machine vision and computer scientists in the company, backed up by the machine vision and robotics department at Loughborough University.

Restrictions
Traditional methods for defect detection rely on human inspection which is ineffective, with detection rates under 65%, while the Shelton WebSpector machine vision system offers a sophisticated platform for automated defect detection of over 97%, but until now has been restricted to plain textiles.

While pattern matching and neural network approaches have previously been tried for patterned textiles, they have failed to provide a practical solution due to the extreme complexity associated with pattern matching on deformable substrates like textiles, as well as the time required to train a neural network for each pattern type.

Challenges
The challenge is that fabrics are not rigid and can be creased or stretched and are also subject to local distortion,” says Shelton Vision Managing Director and CEO Mark Shelton. “As a result, inspection without the technique we have developed, would lead to thousands of false positives. Our sophisticated pattern inspection software techniques ensure a clean image, allowing the detection of faults on fabrics running at speeds of up to a hundred metres a minute.”

The full system consists of:

• A camera and lighting system for optimum image capture at high speed and associated image processing hardware.
• Self-training software utilising statistical analysis to automate the system configuration for new textile products.
• An advanced suite of defect detection algorithms for the detection of all textile defect types.
• An AI-driven defect classification system which learns and automates defect naming in real time, as well as a real time defect grading capability based on client decision rules.
• A system for recording and retrieving complete roll map images for subsequent review and quality control.

The generation of textile roll maps with complete defect data allows for an optimised textile cut plan, improved downstream processing and quality assurance.

Leading computerized knitting machine manufacturer SHIMA SEIKI MFG., LTD. of Wakayama, Japan, together with its Turkish sales representative TETAS A.S., will participate in the CAITME 2022 Central Asian International Textile Machinery Exhibition in Tashkent, Uzbekistan next month.
