Leigh custom-blends QuietLeigh fibers to suit suppliers’ production processes and components, typically floors, doors, speaker enclosures, closeout panels, and package trays.They can help customers meet automotive standards and OEM specifications for sound deadening and flame retardancy.Leigh Fibers, North America’s only ISO-certified fiber reprocessor, can also help customers recycle the scrap from their production and turn it into material they — or another company — can reuse.

QuietLeigh recycled fibers are also finding a home in construction, where custom blends of natural fibers are used in ceiling tile.Other blends show promise as cost-effective alternatives to traditional wall and ceiling insulation materials.As in automotive applications, the fibers are custom-blended to meet customers’ needs.

In addition to helping manufacturers meet cost, performance and sustainability targets, QuietLeighfibers help reduce the thousands of tons of denim and other textile waste that end up in landfills each year.They also appeal to the growing consumer preference for ecofriendly products.

Reduced Formaldehyde Content for Permanent Flame-Retardant Textiles
The Munich-based WACKER Group has developed a novel dispersion tailored to textiles with stringent flame-retardancy requirements. This new self-crosslinking copolymer dispersion is based on vinyl chloride and ethylene with a reduced formaldehyde content. It features high heat resistance, excellent adhesion to textile fibers, and a wide range of processing options, including spray-application and impregnation. This makes VINNOL CEN 2752 ideally suited for the manufacture of flame-retardant fabrics and nonwovens.

VINNOL CEN 2752 is an aqueous copolymer dispersion made from vinyl chloride and ethylene. It is an excellent binder for coating modern textiles and nonwovens. The high proportion of vinyl chloride in the base polymer makes it especially suitable for flame-retardant finishing of textiles such as upholstery fabrics and sun-protection articles, e.g. sunshades and blinds, used in the domestic and commercial sectors. It has excellent stability in combination with flame-retarding additives such as inorganic and organic phosphates or aluminum hydroxide. VINNOL CEN 2752 also allows a significant reduction in the amount of flame-retarding additives required for a permanently flame-retardant finish on textiles.
The new dispersion adheres reliably and permanently to cellulose as well as to synthetic fibers and polyvinyl chloride (PVC) coatings.

Furthermore, it has a high wet strength, a stable viscosity, and good wash resistance. Nonwovens and textiles coated with VINNOL CEN 2752 have a high chemical resistance and can be heat sealed or high-frequency welded. The dispersion is simple and versatile to use and can be applied by spraying, impregnation, and foaming, etc. It can also be used for adhesive bonding of PVC to cardboard, paper, and fiber materials.

As further advantages, VINNOL CEN 2752 is plasticizer-free and has a lower formaldehyde content than conventional self-crosslinking vinyl chloride copolymer dispersions. The dispersion complies with the latest product safety requirements. VINNOL CEN 2752 is thus ideally suited as a binder for soft nonwovens and as a coating for woven and knitted fabrics, particularly for modern flame-retardant textiles. Typical applications include coating of upholstery, floor coverings such as PVC and needled felt or for heat-sealable wadding materials.

NatureShield Natural Oil Emulsions
Michelman is offering NatureShield, a new line of environmentally-friendly, water-repellent additives for interior and exterior wood, stone and concrete coatings. All are emulsions of natural oils and waxes that provide excellent water resistance and water beading when used in coatings, stains and sealants.

NatureShield 30 is an emulsion of tung oil that provides a tough, highly water-resistant finish that does not darken noticeably.It produces water
beading and hold out in exterior wood stains and sealants, and is also used because of its light golden tint.When used in coatings for stone surfaces, it provides durability and a desirable “wet” look when dry.

NatureShield 31 is an anionic emulsion of natural oils and waxes that provides excellent water resistance and water beading in topical wood coatings.It helps prevent wood from swelling in the presence of water, and is typically used in wood stains and sealants.

NatureShield 40 is a film-forming natural oil emulsion used to provide water resistance in both wood and concrete coatings as well as moderate scratch and mar resistance.It will also create a “wet” look on stone surfaces.

Adaptive Phasing Technology
Accucentry’s SingleCull Package can reduce waste for absorbent hygiene manufacturers via Adaptive Phasing Technology that is available on the newest version of AccuSentry’s Sentry 9000 inspection systems. The patent pending technology effectively synchronizes reject signals from multiple inspection points and accurately pinpoints the delay timing to reject only the defective product as detected by the system. According to AccuSentry executives, the technology can decrease material scrapping from process defects in diaper, adult incontinence and feminine hygiene production by 66-80%. Currently three to five products are scrapped per incident as operators have trouble accurately synchronizing the delay timing of the reject gate at full production speeds.

“We want the operator to be able to make the adjustment before having to reject a single product, but if the product is bad, we want to make sure they scrap the right one and only that one,” said Dr. Tan, president & CEO for AccuSentry. This means re­duced waste and downtime. Improving over­all equipment efficiency is essential in the absorbent hygiene industry. Accusentry will first roll out the technology in a cooperative project with GDM and will present it this month at INDEX 11.

The SingleCull technology builds on AccuSentry’s deep com­­mit­ment to the nonwoven and absorbent hygiene industries.

It complements AccuSentry’s Centerlining technique, first introduced at Insight in 2010, which delivers operators vital realtime data on a screen of control graphs measuring product attributes like position, length, width and other parameters during full speed production. When the product is being produced within a specified target range, the graphs are white; when the product begins to drift out of range they turn yellow and when things are bad, they are red so the operator needs to take only one look at the screen to see there is a problem. Dr. Tan said operators could at first meet this technique with resistance, until they see how effective it is. “At first, they see the Centerlining and they think it’s too much information but when we do training, it leads to a real ‘a-ha’ moment with the operators who see how successful it can be.”

The technology has been nominated for an INDEX 11 Award in the innovation in machinery category.
