Yarn manufacturing

OSHA has determined that worker exposure to cotton dust presents a significant health hazard cotimonly referred to as byssinosis ( ). This respiratory disease is characterized by shortness of breath, cough, and chest tightness. Permissible exposure limits have been established for selected processes in the cotton industry 200 ug/ni or less in yarn manufacturing,... 

The OSHA standard establishes a permissible exposure limit of 200 ug/m for yarn manufacturing, 750 ug/m for slashing and weaving, and 500 pg/m for all other processes in the cotton industry and for nontextile industries where there is exposure to cotton dust (1). The standard specifies that concentration is... 

In summary, when cotton is grown and processed (including yarn manufacturing and wet processing) in a responsible manner, the production of cotton should not have any adverse effects on the environment (through external emissions, wastewater effluents, and solid wastes), the workers (because of acute or chronic effects), and the consumers (because of acute or chronic effects). 

Draft ratio n. The ratio between the weight or length of fiber fed into various machines and that delivered from the machines in spun yarn manufacture. It represents the reduction in bulk and weight of stock, one of the most important principles in the production of yarn from staple fibers. 

Frame n. (1) A general term for many machines used in yarn manufacturing such as the drawing frame, roving frame, and spinning frame. (2) See tenter frame. 

Noil noi(o)l (ca. 1624) n. A short fiber that is rejected in the combing process of yarn manufacture.

In a manufacturing location, usually in excess of 2000 samples are tested to engineer raw material for yarn manufacturing thus, further automation of the near-IR technique would be helpful. Figures 6 and 7 show photogra-... 

As soon as an item is purchased, the retailer collates the the electronic point of sale (EPOS) data from its stores, and sends the data upstream. The pull signal (Chapter 6) goes back all the way to the yarn manufacturer. Figure 8.3 represents the path that a garment might take from concept to delivery. Six stages are involved.
