Trend of Jute Machinery Development for Jute Industry.

An overview of trends in jute processing describes IJIRA machinery developments int he areas of softening, breaker and finisher carding, drawing, spinning, spool and cop winding, beaming, weaving, and sewing. For softening, IJIRA reduced the pairs of rolls from 64 to 16 without impairing the quality and softening of fibers. The introducti..

Do We Have Too Many Varieties of Cotton?

Although India produces more than 100 varieties of cotton, the International Textile Manufacturers' Federation recommends that not more than three varieties be cultivated in each state. Too many varieties prevent textile mills from maintaining yarn quality standards. Analysis suggests, however, that reducing the number of varieties will n..

Harvest and Post-Harvest Factors Affecting the Quality of Cotton Planting Seed and Seed Quality Evaluation.

Mechanical damage to cottonseed adversely affects its reproduction performance. An overview of the harvest and post-harvest operations that affect cottonseed quality addresses mechanical damage, including damage resulting from harvesting, ginning, mechanical delinting, handling, and conveying; mechanical properties of the cottonseed coat;..

Structural study on PBP fiber

PBO (poly-p-phenylenebenzobisoxazole) is one of rigid-rod polymers, which originated from stream of the ladder polymers made by US Air Force in 1970s. [1]. PBZT(poly-p-phenylenebenzobisoxazole) was firstly examined, then PBO followed, which was advantageous in performance and cost. As for commercialization as a fiber, Dow Chemical develop..

New antibacterial acrylic fiber

Antibacterial properties are often given to synthetic or artificial fibrs by adding organic or inorganic additives. As an alternative to this, special zeolites or ceramic substrate containing silver or zinc ions have also been used. It has been found however that using inorganic additives results in the production of low dtex fibre. This ..

Fibres containing fine metallic particles

Japan Exlan have developed a range of fibres which contain fine metallic particles. The company explains how specific and often unusual characteristics can be conferred on fibres by the incorporation of fine metallic particles or virtually insolube salts of metals. Distinctive properties such as antibacterial, antifungal, odour repelling ..

Biodegradable polyurethane urea fibres support natural healing process

Recent research has focused on new approaches to healing injured anterior cruciate ligament (ACL). The aim is to develop an artificial ligament which can offer a scafford for fibroblasts to form new collagen and give support. Polyurethane urea (PUUR) has been found to have suitable mechanical properties and degradation rates, and biocompa..

Fibres containing fine metallic particles

Hoechst Celanese has created a cut resistant fibre which the company is promoting for use in industrial gloves. The yarn is a composite structure comprising of: a fibre with a modulus of more than 200 gpd; and a particle filled fibre made from a semicrystalline polymer such as polyethylene terephthalate. Fabrics made from these composite ..

New polyolefin fibers : New applications and properties

Asota GmbH of Austria has developed AM Saritized, a technique which makes the fiber permanently antimicrobial. Final products include socks, aminal baskets and bedding. The company has been producing PO fibers for 25 yrs and has perfected incorporating additives (eg spondyes, pigments) during fiber production.

Polyasparaginic acid (PAS) - phosphonate substitute and dispersing agent

Dyeing investigations with hardness sensitive dyestuffs were carried-out on cotton in hard water in which the hardness influence of the addition of a new, natural analogue and readily biologically degradable polymer, polyasparaginic acid was tried as a phosphonate substitute. Similar results were obtained with respect to dyestuff properti..
