Calculations in Yarns and Fabrics
Calculations in Yarns and Fabrics
Book · 311 pages · weaving drafts
A 1906 textbook of arithmetic and formulas for the textile trades, written by the head of textile industries at the Belfast Municipal Technical Institute. It covers yarn counting systems (cotton, worsted, woollen, linen lea, silk, jute), resultant and average counts, twist yarns, blending and yarn costing, reed and heald sett systems, warp and weft quantities, and the weight and cost of woven fabrics. Later chapters treat fabric analysis and reproduction, conditioning and moisture allowances, and the theory of fabric construction (thread diameters, balance of structure, angle of curvature, compression). Worked examples and exercises with answers close each chapter, and a few threading and draft diagrams illustrate the heald calculations.
Flax Culture and Preparation
Flax Culture and Preparation
Book · 187 pages
A technical textbook on growing flax and preparing it for market, from the Pitman's Textile Industries Series. It follows the crop from the plant, fibre and seed through soil, manures, sowing, weeding, pulling and harvesting, then deseeding, retting (pond, dew, tank and warm-water methods) and scutching by hand and machine, and ends with marketing of flax. It is illustrated with line drawings of machines, graphs and photographs, and includes an index. The focus is Irish and Belgian practice.
Jacquard Mechanism and Harness Mounting
Jacquard Mechanism and Harness Mounting
Book · 369 pages · weaving drafts
A 1912 technical treatise on Jacquard weaving by Fred Bradbury, a textile professor in Belfast. It traces the development of figure weaving from treadle looms and the draw loom through the early French and British Jacquard precursors, then describes single lift, double lift, double cylinder, cross border and twilling Jacquard machines, with their driving and counterpoise systems. Later chapters cover gauze/leno Jacquards, the swivel and gauze reed, pressure and split harness mechanisms, harness mounting and its calculations, and card preparation (design, stamping, repeating and lacing machines). The book is heavily illustrated with mechanical line diagrams and includes worked problems and an index.
Worsted Preparing and Spinning, Vol. 1
Worsted Preparing and Spinning, Vol. 1
Book · 296 pages
Volume I (Third Edition) of Fred Bradbury's technical textbook on worsted manufacture, following wool from the greasy fleece to the clean, carded sliver. It covers sheep breeds and wool sources, the effects of climate and pasture, impurities, chemical reactions, fibre structure and felting, classification and sorting, then scouring, washing and drying machinery. It goes on to gilling and drafting calculations, oiling, opening and burring machines, and carding, including card clothing and the functions of the card rollers. Illustrated with many machine diagrams, micro-drawings of wool fibres and tables.
Worsted Preparing and Spinning, Vol. 2
Worsted Preparing and Spinning, Vol. 2
Book · 304 pages
Volume II (second edition, 1923) of Fred Bradbury's treatise on worsted preparing and spinning, devoted to wool combing and its subsidiary processes. It covers intermediate processes between carding and combing (backwashing, bleaching, drying), then the Noble comb in great detail: history, mechanism, pinning and set-over, feeding, dabbing, drawing-off, sliver funnels, can coilers and stop motions. Other combs treated include Cooper's Noble comb, the Lister or nip comb, the square motion comb and the Heilmann comb, followed by finishing gill boxes, conditioning, and material and production costs with worked examples. Illustrated with many mechanical line drawings and gearing and pinning tables.
Worsted Preparing and Spinning, Vol. 3
Worsted Preparing and Spinning, Vol. 3
Book · 348 pages
Volume III of Fred Bradbury's technical treatise on worsted preparing and spinning, covering the drawing and spinning stages. It treats gill and drawing boxes, knocker-off and lifter/builder mechanisms, principles of drafting and twist, reduction and production calculations, differential bobbin winding (cone drawing) and differential gear mechanisms, French drawing, flyer, cap, ring and mule spinning, mechanical doffers, twisting and fancy yarns, and warp winding and warping. The text is heavily illustrated with machine diagrams and worked arithmetic examples and tables, and includes a historical account of the spindle, distaff, jenny, mule and flyer.
