Combustion phenomena in polymers and fibres. General problems

Continuous growth of manufacturing and consumption of polymeric materials has been observed for a many years. The majority of polymers, however, demonstrate undersirable inflammability, causing many disasters and material losses, therefore investigation into the reduction of polymer flammability is one of the main problems to be solved in..

Effect of graft-copolymerization of vinyl phosphonate oligomers and/or N-methylolacrylamide on pyrolysis of cotton cellulose (Japanese)

Thermal decomposition behaviour of cotton fabrics graft-copolymerized with vinyl phosphonate oligomers (Fyrol 76) (RYR) or N-methylolacrylamide (NMA) or with combination of FYR and NMA was studied in relation to P or N contents of the treated cotton sampl

Investigation of the technology for wool and silk blended (Chinese)

Wool and silk blended product is a most up-date fabric. It's a trend that worsted factories utilize a small quantity of silk to improve it's comfort and lustre of worsted fabric, enhance yarn count. This paper has probed into the spinning problems occuring in production, put forward a set of reasonable spinning technology, analyzed the ma..

Strategies to combat foreign fibres (German)

The following points are discussed: systems for the detection and elimination of foreign matter in the spinning mill (foreign matter detection in the blowroom and using electronic yarn monitoring systems); extraction of foreign matter with conventional blowroom equipment; effect of foreign matter removal in the blowroom on foreign fibre c..

Flax fibre-length - one of the main properties which defines the processing of flax in textiles (Romaina) (Lungimea fibrelor de in - una din proprietatile principale care definesc prelucrabilitate inului in textile)

The work presents a detailed analysis of length distribution of fibres delivered to machines in conventional spinning preparation of flax bundles in comparison with normal distribution. This analysis was carried out by means of assymetry curving and excess coefficients established for each stage of analysed flow sheet.

Ramie - king of natural fibres

Ramie is hygroscopic in nature and typical surface characteristics made it difficult to spin by conventional spinning processes. But it can be spun in a modified spinning system used for other natural fibres like flax and jute which have long staple length. The physical and chemical properties of ramie fibres are described. The main advan..

Effect of compacting on the condition of raw cotton during long-term storage (Russian)

The effect of compacting on fibre length and the density of cotton bales during storage is investigated. To maintain the correct fibre length and cotton quality the bale density must not exceed 250 kg/㎥. A uniform bale density is also desirable.

Examination of the differences between OFDA and LASERSCAN on ultrafine wools

Previous submissions to IWTO have shown that the OFDA and Laswerscan give compatible results over the normal working range, but systematic and commercially-significant differences have been observed on ultrafine lots. Detailed investigation has been carried out to establish the reasons for this. Evidence is presented which indicates that ..

Wool market review

Wool prices, production and stocks on the world market are discussed. Factors influencing wool prices are also considered, together with the world economic outlook and the global wool supply. Other technical fibre markets are reviewed, particularly that for cotton.

New fibres for garment fabrics

Methods for assessing the commercial viability of new and modified fibres for clothing are outlined, with examples. The assessment procedures recommended are based on many years of experience in downstream markets.
