Air-jet weaving machines     

Using special machine settings, the Relanit 3.2 II Processes both cotton and synthetic yarns at high output without problems.

No other machine knits more.

With a speed factor of SF 1.500, the Relanit 4.0 is the world’s most productive single jersey circular knitting machine, illustrated here as a body widthmachine with Giant frame for fabricbales up to 1,200 mm in diameter.

Molecular structure of cyclodextrins

Intelligent freshness and actively fighting unpleasant smellProduct: CyclofreshProducer: CognisApplication: Pad-DryCompatibility: Can be used in finish bath with other softeners

Cyclodextrin is derived from starch by adding Enzymes – mainly from maize – and it has already been used for a number of years in the pharmaceutical industry. It is also valued in the cosmetics industry because of its high skin compatibility.

Cyclofresh is based on this entirely renewable,Natural raw material that is readily biodegradable.

SBY-750X6GIII Rolling-column Style Six-shuttleCircular Loom have the following features:

1. Original rolling column track reduces 50% spare parts and reduces the noise greatly.

2. Compared with four-shuttle circular loom, its output increases more than 30%, saves 30% electricity consumption and reduces 30% covering area. 3. It can use the lower denier flat yarn or inferior quality flat yarn to weave bags.

4. It can stop automatically when the warp or weft are broken or the weft used up.

5. It can adjust weft density and compensate weft automatically.

CIRCULAR LOOM

On dyeing Polyester/spandex blends with disperse dyes, reproducibility deteriorates as disperse dyestuff stains heavily on (is adsorbed into) spandex. This kind of dyeing also often involves other trouble such as production of insufficient fastness. By adding Neoleve SDX-D to the dye bath, it potently prevents disperse dye from staining on (being adsorbed into) spandex, and helps its further distribution in polyester. Furthermore, Emill NW-1570 used in Finishing after dyeing further washes off stains, leading to good reproducibility and colorfastness to washing/dry-cleaning (less staining in test liquor). Standard Usage

Disperse dyestuff is adsorbed in spandex up to around 100°C, then as the temperature rises, it begins shifting onto polyester. Higher temperature is preferable, however, with spandex' other physical characteristics taken into consideration, dyeing is normally carried out around 120°C. If the spandex blending rate is so low that its colorfastness can be ignored, soda ash instead of caustic soda (NaOH) is used.

Anti-staining properties of Neoleve SDX-D (colorfastness to dry cleaning and washing, residual-liquor absorption) were tested following the method below.

RC conditions are the same in 1A, 2A and 3A.

Colorfastness of 1A, 2A and 3A were examined after being set and performances of anti-staining agents were compared.

1) Dry cleaning fastness: the less bleeding denotes the better performance.

2) Washing fastness, washing fastness tested based on JIS A-2 method with white silk and polyester pieces attached. After taking out the pieces, nylon jersey added in the residual liquor, 80°C x 30 min. The paler color denotes the better performance.

3) Absorption in residual liquor:

PBT: Polybutylene terephthalate is a texturised polyester filament yarn with properties of stretch and elasticity. PBT has higher stretch and recovery compared to standard polyester types and this property is also improved by special texturing conditions. The exceptional stretch and recovery of PBT are achieved through high elastic shrinkage in finishing processes. The amount of stretch depends on the amount of PBT used and the fabric construction. PBT is also resistant to alkalis, salt water and chlorinated water. (POLY-tera)

The Development and Future of Circular Knitted Fabric

As the quality of life continues to improve and with it the desire for more individual clothing, different demands are made with regard to designand quality. More versatile products become necessary and theproduced quantities per product are forced downwards. It is preciselythe advent of the leisure society and the many possibilities for sportand other activities that are creating the demand for fashionable and

functional products which has to be satisfied at short notice.
