The formation of cotton knitting fly

Knitting fly is identified with the impossibility of collection at one location and regular machine cleaning needed to remove it. Fabric defects can occur and it is a health hazard to operatives. Yarn abrasion and amount of fluff liberated depend on wrap of the yarn around different guides, yarn-input tension, coefficient of friction betw..

Development of polyester yarns with low oligomer comtent for automotive upholstery fabrics

Automotive fabrics have to have high abrasion, good colourfastness, temperature tolerance and comfort characteristics. In most cases polyester yarns are used, but during the high temperature dyeing process large amounts of oligomers are released which contaminate the dye liquor and affect the down stream production processes as well as in..

A Rapid Analysis of Oily Substances by ATR/FT-IR -- An Application for Soil from the Human Body Deposited on Fabrics.

Attenuated total reflection Fourier transfer infrared(ATR/FT-IR) spectroscopy evaluated oily substances with ester bonds and fatty acids in an n-hexane solution. Experiments analyzed the residue on an internal reflection element after n-hexane evaporation. When the amount of residue was 0.5-5 micrograms, absorbance data identified triolei..

Role of Fibre Properties in Colour Non-uniformity of Dyed Fabrics.

A spectrophotometer determined variations in dyed cotton 7and manmade fabric color uniformity. Such fiber properties as micronaire, maturity ratio, and fluorescence affected shade variation in the dyed fabrics. Image processing techniques determined cotton fiber maturity. The study resulted in an equation relating fiber properties to colo..

Effect of Mechanical Properties on MIT Drape Behaviors of Fabrics

Experiments and simulations revealed the effects of fabric mechanical properties on fabric MIT drape behavior. An improved MIT device detects fabric drape shapes with greater reproducibility. A nonlinear finite element method combined with an incremental method in which an elastic shell models the fabric simulated large deformation of a f..

Objective Evaluation Method of Appearance of Fabric Wrinkling Replica by Image Processing System.

Tests of an image processing system indicated that the system can measure fabric wrinkling using gray level distribution, ratio of surface area, and ratio of X and Y direction surface profiles. The system used overhead fluorescent illumination in a small dark room providing 756 Ix illumination on the horizontal surface of the tested fabri..

Modeling a Fabric Drape Profile.

A polar coordinate fitting model predicts the drape coefficient and node location, number, and shape in the fabric profile. Experimental drape profiles of 35 woven fabrics agreed well with constants determined by polar coordinate fitting. Calculated drape coefficients agreed with experimental drape coefficients, indicating that bending an..
