TS 1417

TS 1417 is a terminology standard for the operation stages used in worsted spinning. It brings together the technical names and meanings of the main steps associated with raw wool washing, combing in the continental system, tops preparation, and the wider worsted spinning route.

Why the operation names matter in worsted processing

Worsted spinning is aimed at producing a more orderly fibre assembly, with better alignment and a cleaner, more even sliver or yarn path than is typical in more open fibre preparations. In that context, washing, combing, and tops formation are not interchangeable ideas: each refers to a distinct stage in preparing wool for subsequent spinning. Clear terminology supports production control, technical communication, and teaching, especially where the same material passes through multiple preparatory steps.

What this standard includes and leaves outside its scope

• It covers the operation stages involved in washing dirty wool.
• It includes combing and tops preparation only as limited to the continental system.
• It provides definitions for the operations used in worsted spinning.
• It does not cover the preparation of washed wool, hairs, viscose, or other fibres.

In general textile terms, worsted and woollen systems differ in fibre selection, drafting behaviour, and the degree to which fibres are parallelised before spinning. TS 1417 is therefore best understood as a terminology document that standardises the vocabulary of this preparation chain, rather than as a process specification with production limits or test requirements.

For users working with wool processing language, the value of the standard lies in making the step sequence, the continental combing reference, and the boundaries of the worsted route easier to interpret consistently across technical documents.
