FIRMLY COMMITTED TO DYTEX CUSTOMERS

BMM Weston's Dytex range of rotary machines, acquired with the purchase of the Spencer company, are used to dye knitwear and women's hosiery. Hosiery made of nylon, acrylic, wool/nylon, and cotton can be processed. Acrylic, lambswool, and botany knitwear has been successfully dyed using the Dytex range. The latest Dytex machine is designe..

PIGMENT DISCHARGE ON REACTIVE GROUNDS.

Knit and woven cotton fabrics were dyed or printed with reactive dyes based on vinyl sulfone. The fabrics were then printed by discharge printing. The process sequence, machinery, and chemicals were varied in a series of four experiments. The process was performed with and without steaming/curing. Samples were tested for rubfastness. Rubf..

TEXTILE DYEING AND PRINTING IN SMALL SCALE SECTOR IN SOUTH INDIA. PART 1.

The dyeing and printing industries in South India use mostly manual techniques. Silk, cotton, and viscose yarn and some fabrics are dyed. Hank dyeing yarn with direct and/or vat dyes for weaving sarees on handlooms is a common practice. Handwoven fabric for sarees are printed with reactive dyes or pigments. Direct dyes with good fastness ..

RECENT DEVELOPMENTS IN TEXTILE PROCESSING MACHINERY.

Recent technical developments for a variety of textile machines are briefly reviewed. New machines for singeing, bleaching, cleaning, cropping, and shearing are considered. Benninger's DIMENSA merserizing machine, knit goods mercerizing machines, and a mercerizer for small outputs are discussed. New continuous and batch dyeing technology ..

'Babco-Star' - the new generation of stenters

Describes the new 'Babco-Star' stenter from Babcock Textilmaschinen, geared towards improved fabric quality, increase in continuous production output, improvement in utilisation rate, minimisation of maintenance input and reduction in energy consumption.

Assessing the threat to ecology in the Polish cotton industry (Polish)

The impact of mercerizing, bleaching and desizing in the cotton industry on the environment is evaluated. Water and energy conservation are discussed. The ecological threat posed by dyeing and printing processes is assessed. The effectiveness of methods of treating effluents (both liquid and gaseous) is considered.

Development of ecofriendly product for pigment printing

Non-formaldehyde based agents are being studied in order to substitute existing formaldehyde (HCHO) based products due to their known carcinogen character. The author reports on experiments undertaken in pigment printing. Sunnyfix NF is introduced as totally free from formaldehyde, which shows good fastness characteristics and less tenden..

Mechanical properties of polyester yarns and fabrics treated with various heat temperatures in dyeing and finishing processes

This research surveys the relationship between mechanical properties of polyester filaments and fabrics treated with various wet and dry heat temperatures in dyeing and finishing processes including sizing. Used polyester filament for warp is 50d/24fil spark, and 75d/72fil semi-dull for weft. Plain fabrics were woven by shuttle weaving ma..

Color Difference Evaluation

The CIELab Space or L*a*b standard is the most widely accepted equation for color evaluation. It is a three axis system comprising lightness (L*), the amount of red or green (a*), and the amount of blue or yellow (b*). L*, a*, and b* values derive directly from the tristimulus values via a series of standard equations. However, the standa..

A Comparative Study of a CRT Colorimetric Prediction Model by Neural Networks and the Models by Conventional Method

Researchers developed a CRT colorimetric prediction model using a set of artificial neural networks (ANN) in which a set of back propagation (BP) neural networks performs a nonlinear conversion between red, green, and blue (RGB) values and tristimulus values (X.Y.Z). Theoretical comparisons of the neural network based model with conventio..
