Encyclopedia article on the alpaca, both the South American domesticated animal and the fibre and fabric made from it. It covers the animal's habitat and wool colours, the history of alpaca cloth manufacture in Europe (Benjamin Outram, Titus Salt, Bradford cotton-warp fabrics), and trade statistics for imports and exports of alpaca, mohair and yarns up to 1905. It ends with notes on failed acclimatization attempts and the llama hybrid 'Huarizo'.

A late Victorian technical textbook by Aldred F. Barker of Bradford Technical College on how to analyse woven cloth and work out the particulars needed to reproduce it. It covers yarn construction, counts, twist and cost calculations, weave analysis, drafting, figured fabrics and jacquard work, gauze and leno, pile fabrics and Brussels carpets, setts, and cloth weights in the loom and after finishing. Appendices cover the cost of cloths, fabrics that are difficult to analyse (Meltons and fine-sett silks), and design paper selection. It includes many weave designs and drafts, diagrams, and worked arithmetic examples.

A 1914 technical treatise on analysing woven cloth, written by two Yorkshire textile teachers. It covers raw fibres and yarn qualities, yarn count and cloth weight calculations, setts, weave analysis, drafts and pegging plans, and the effects of dyeing and finishing on wool, union and cotton cloths. It explains how to work back from a small finished sample to loom particulars, with worked examples (worsted costume cloth, mohair lustre, double cloth, corduroy, colour-and-weave cloths), quick methods, fibre analysis, costing and wage lists. It ends with a glossary of fabric terms, an appendix of weaving price lists and a publisher's catalogue.

Encyclopedia article from the 11th edition of the Britannica describing felt as a fabric formed by matting wool, fur and hair fibers. It distinguishes woven (thread-structure) felts from true fibre felts, reviews the early history of felt in Asia and the ancient world, and outlines manufacture: mixing, willowing, scribbling, carding, ironing, fulling. It also covers hat felts and impregnated felts such as asphalted roofing felt and iron-felt, with British manufacturers named.

A 1912 paper by Prof. Aldred F. Barker comparing frame (ring) spinning with mule spinning of woollen yarns, with a brief note on worsted drafting. It explains the principles of woollen mule spinning (spindle draft, drafting twist, the old piecening carder versus the modern condenser) and describes Platt Bros.' patent woollen ring spinning frame with its twister tube. It gives cost, space and power comparisons and strength and elongation tests of yarns and cloths from three blends, with photomicrographs and drafting-roller diagrams, and ends with the discussion by Institute members.

A 1903 technical college textbook on textile design and cloth construction by the head of textile industries at Bradford Municipal Technical College. It covers simple interlacings and drawing flat views and sections, warp preparation, drawing-in and sleying, hand, dobby and power looms, yarn counts and cloth setting calculations, and the designing of weaves on point-paper. Further chapters treat twills, sateens, drafting and pegging plans, colour-and-weave effects, backed and double cloths, lustre goods, and yarn and cloth calculations, with design sheets, plates and photographs throughout. The scan ends with a publisher's catalogue.

A survey by Professor A. F. Barker of Leeds University tracing how mathematics came to be applied to yarn and cloth construction from about 1880-1890 onward. It covers Ashenhurst's yarn diameter rule and cloth geometry, the idea of twist defined by angle rather than turns per inch, and graphs and nomograms that relate twist angle, yarn count and turns per inch. It closes with the confusing variety of regional textile units and the groupings needed to set up a loom for figured cloth. Illustrated with diagrams of thread interlacing, twist charts, a nomograph and two-fold yarn twist types.

A comprehensive 1910 textbook on the textile industries from the Westminster Series, written at the Bradford Technical College. It covers the history of textile inventions, fibre production (wool, silk, cotton, flax), artificial and mercerized fibres, dyeing, spinning, preparatory machinery, weaving principles, design and colouring, finishing, yarn calculations, and the woollen, worsted, dress goods, carpet, silk, cotton and linen industries. Chapters by Gardner, Snow, Cook and Bradbury are included. The book has many machine diagrams, micrographs, statistical tables and a few weave and loom-mounting diagrams.

Paper by Professor A. F. Barker of Leeds University, read at the Textile Institute's Autumnal Congress in 1915, on weaving delicate single warps of botany and crossbred wool with centre-shed tappet motions rather than open-shed tappets. It argues that centre-shed tappets reduce warp tension, thread breakage, heald wear and power consumption, and it explains cam design for 2/2 and 3/3 twill tappets, with diagrams, tachograph speed records and tables of power use and mending costs. The paper also covers Continental competition in twill and serge fabrics, and it ends with the discussion that followed.

A 1912 technical textbook on the preparation of wool for spinning, written by two Bradford Technical College instructors. It covers sheep breeds and breeding (including a chapter on Mendelism), wool and hair types from Britain and the colonies, wool classing and sorting, fibre properties, scouring, drying, and yarn types and twist. The final chapters describe the machinery for preparing, carding and combing, including gill boxes, carders, backwashers and circular combs, and a table of Bradford tops grades. It is illustrated with photographs of sheep, fibre micrographs, machine drawings, charts and tables.

Encyclopedia Britannica (11th ed.) article on wool and the woollen and worsted industries. It covers the nature of the wool fibre, the history of wool use and sheep breeds (merino, cross-bred, English long wools), and the wool trade and statistics. It also describes the manufacturing processes in detail: sorting, scouring, carding, combing, drawing, spinning (flyer, cone, cap and French systems) and cloth finishing. Illustrated with a plate of fibre photomicrographs and machine diagrams, and with tables of wool imports, prices and UK factory statistics.
