Document management system and method for business quality modeling

A computer implemented system and method and a computer readable medium for complying with the requirements of a quality standard known as ISO 9000. The areas covered include controlled documentation, training management, meetings and reports, process improvement requests, project management, and audit management. All controlled documents have a security and revision control portion that controls the access and approval capabilities of the documents. The system is form controlled. Certain individual fields of the forms require the entry of data, and field's control are controlled by certain fields of other forms, with the fields being updated by other fields in the system, operator entry of data, and a combination of control by both the system and operator entry. The system includes an ISO matrix relating each document to an ISO clause. The system has a controlling document for each delineated activity, and all other documents relating to such activity are linked as a child of the controlling document. An audit trail is created by storing and making available previous iterations of current documents as child documents, insuring that the first issue, subsequent changes to content, movement to draft status, reprieval, and reissue are available for auditing the activities of the business.

Processing method of double-component elastic spandex core-spun yarn

The invention discloses a processing method of a double-component elastic spandex core-spun yarn, comprising raw materials, production steps and production process improvement thereof, wherein the raw materials include a first elastic spandex filament, a second elastic spandex filament and wrapping yarn; the second elastic spandex filament is half of the first elastic spandex filament in diameter, and the two elastic spandex filaments differ in traction multiple; and the wrapping yarn is a short fiber; the production steps include: rolling the comparatively thick wrapping yarn into the form of a flat strip; before entering into a spinning room, guiding both the elastic spandex filaments as double cores to the middle of the flat-strip shaped wrapping yarn; folding the flat-strip shaped wrapping yarn by taking the double cores as a fold line, and covering the double cores on the fold line in the flat-strip shaped wrapping yarn; feeding the double cores and the folded flat-strip-shaped wrapping yarn into the spinning room, and stretching and twisting in an 8-shaped form to form the double-component elastic spandex core-spun yarn. The product is elastic and free from the feeling of being too tight on the body, and overcomes the shortcoming of being insufficient in elasticity or too tight.
