Cotton is traditionally the most important natural fibre in the apparel industry because of the comfortable wearing comfort and durability of cotton textiles. The chemical finishing of cotton aims to further improve the quality of the cotton fibre, either to overcome some disadvantages of the apparel or to establish additional desirable properties. This paper highlights some current trends in c...

From 2004 through 2005, plots of experimental transgenic cotton lines containing the vegetative insecticidal protein, Vip3A; δ endotoxin, Cry1Ab; and both Vip3A and Cry1Ab were evaluated for efficacy against certain lepidopteran pests. Results showed that the cotton line containing Vip3A was more efficacious against the beet Spodoptera exigua (Hübner) and fall armyworm Spodoptera frugiperda (J....

The polyphagous mirid bug Apolygus lucorum (Heteroptera: Miridae) has more than 200 species of host plants and is an insect pest of important agricultural crops, including cotton (Gossypium hirsutum) and mungbean (Vigna radiata). Previous field trials have shown that A. lucorum adults prefer mungbean to cotton plants, indicating the considerable potential of mungbean as a trap crop in cotton fi...

R. of China 071001 [email protected] China Agricultural University; CIRAD, Annual Cropping Systems, Montpellier, France Abstract: In order to analyze the impacts of Bt cotton on the farmers’ livelihood system, we interviewed 169 farmers and extension personnel in the main cotton production areas in He...

A new cotton recognition method is proposed in this paper. It provides parameters for motion of the manipulator so that it can acquire precise location information of cotton, identify cotton from surroundings correctly, and accordingly pick up them automatically. This method is based on color subtraction information of different parts of cotton. Furthermore, in order to increase accuracy rate o...

Recent developments in cotton (Gossypium hirsutum L.) production technology in the Delta include drill planting cotton in an ultra-narrow-row (UNR) production system. Ultra-narrow-row cotton is a low-input production system designed to maximize economic returns. The premise is that UNR cotton will be lower yielding, but the reduction in input costs will result in a larger profit margin. Researc...

Staple strength (SS) and coefficient of variation of fibre diameter (FDCV) were measured on full length staples from 12 months of wool growth, and wool staples cut to 80 or 60 % of their full length from the tip. The results show that SS and FDCV for the different staple length treatments are heritable but lower for staples 60% or shorter than their full length. SS and FDCV measured on wool sta...

The efficacy of rye (Secale cereale) and wheat (Triticum aestivum) winter cover crops and cotton stalk and root destruction (i.e., pulling them up) were evaluated in field tests during two growing seasons for Hoplolaimus columbus management in cotton. The effect of removing debris from the field following root destruction also was evaluated. Wheat and rye produced similar amounts of biomass, an...

Greige cotton is an intact plant fiber. The cuticle and primary cell wall near the outer surface of the cotton fiber contains pectin, peroxidases, superoxide dismutase (SOD), and trace metals, which are associated with hydrogen peroxide (H₂O₂) generation during cotton fiber development. Traditionally, the processing of cotton into gauze involves scouring and bleaching processes that remove the ...
