From the Sector

BTMA member Vickers Oils has marked an important milestone in its partnership with knitting machinery leader Lonati by earning Original Equipment Manufacturer (OEM) approval for its VICKERLUBE SOCK 46 needle oil.

VICKERLUBE SOCK 46 is a mineral-based needle lubricant designed to meet the criteria for modern knitting machine technology. It provides a high standard of lubrication as well as holding very good stability properties and having a high resistance to oxidation. The product is readily scourable and holds a well-balanced additive system meaning that it is fully compatible with all machine components. It can also be used with machines producing any yarn type – including tricky elastanes – to produce the highest quality end product.

Lonati, headquartered in Brescia, Italy, has been a prominent name in knitting machines for over 70 years, designing and manufacturing an impressive average of 8,000 annually. It places a strong emphasis on delivering the highest quality textile machinery, underpinned by a commitment to research and development that ensures the use of cutting-edge products, technologies and processes in its machines.

Vickers Oils, based in Leeds, West Yorkshire, shares these values, leading the industry in quality and assurance through its continuous focus on research and development, technological leadership, quality control and customer service. As it has done for almost two centuries – the company will mark its 200th anniversary in 2028.

Lonati is now officially recommending VICKERLUBE SOCK 46 for use in its single-cylinder GOAL series of knitting machines, marking a successful collaboration that required dedicated efforts from the teams of Lonati, Vickers Oils and its Italian representative Lubrogamma. Vickers Oils is committed to sustainable product development and VICKERLUBE SOCK 46 meets the clearly defined criteria set out by the Global Organic Textile Standard (GOTS) and conforms to ZDHC MRSL Level 1 certification.

The DiloGroup informs at Techtextil in Frankfurt (June 21 – 24, 2022) about new developments aimed at improving production technologies with a focus on needlefelts.

It becomes more evident that the textile industry comes into the focus of regulatory authorities who push respecting sustainability principles and who initiate a new body of laws. Hence all industrial sectors are requested to achieve savings in material and energy. The textile machine building, of course, plays an important role by seizing this initiative and offering solutions for fibre pulp recycling and reduction of energy, water and ancillaries. DiloGroup has made big efforts to meet these challenges together with a circle of partner companies. In this regard focal points of the development work are:

1. Intense Needling
   Needling per se is a mechanical production method with a high energy efficiency. For this reason, the development efforts of DiloGroup aim at producing nonwovens by “intense needling” instead of water entangling, even for light nonwovens made of fine fibres for the medical and hygiene sector with an area weight of 30 – 100 g/m². This would result in a reduction of the environmentally relevant production costs; per annum to about 1/3 to 1/5 of current.
   Despite the prospective advantages of the mechanical intense needling method over the hydrodynamical, water entanglement is at the moment the most important production method for low area weights and highest production capacity and is also offered by the DiloGroup as general contractor in cooperation with partner companies.
2. “Fibre Pulp Recycling”
   Fibrous material in nonwovens and particularly used clothes can be successfully recycled, if staple length can be conserved in the tearing process. In the classical tearing process, staple lengths are dramatically reduced and therefore these fibres can only be used as base material for inferior uses in thermal or acoustic insulation or in protective textiles, transportation or protective covers etc.
   When recycling textile waste in the context of the collection of used clothes, the so called “filament-saving” tearing using special tearing machines and methods must be used to produce fibres with longer staple lengths which can be fed to a nonwoven installation. Hence product characteristics can be better specified and controlled.
3. Additive nonwoven production
   The additive production method of the “3D-Lofter” is especially suited for automotive parts with differently distributed masses; but there may also be potential for increasing uses in the sector of apparel and shoe production.
4. “IsoFeed”-card feeding
   In the field of card feeding, the “IsoFeed” method offers great potential for a more homogeneous card feeding at the same time reducing the variation in cross-machine fibre mass distribution and thus the fibre consumption while conserving the end product quality.
