Carding

Carding is a mechanical process that disentangles, cleans and intermixes fibers to produce a continuous web or sliver suitable for subsequent processing. This is achieved by passing the fibers between differentially moving surfaces covered with card clothing. It breaks up locks and unorganized clumps of fiber and then aligns the individual fibers to be parallel with each other. In preparing wool fiber for spinning, carding is the step that comes after teasing.

The word is derived from the Latin carduus meaning thistle or teasel, as dried vegetable teasels were first used to comb the raw wool. These ordered fibers can then be passed on to other processes that are specific to the desired end use of the fiber: Cotton, batting, felt, woollen or worsted yarn, etc. Carding can also be used to create blends of different fibers or different colors. When blending, the carding process combines the different fibers into a homogeneous mix. Commercial cards also have rollers and systems designed to remove some vegetable matter contaminants from the wool.

Carding (police policy)

Carding, which is officially known as the Community Contacts Policy, is an intelligence gathering policy of the Toronto Police Service involving the stopping, questioning, and documenting of individuals when no particular offence is being investigated. The information collected is kept on record in the Field Information Report (FIR) database for an unspecified period. The Peel Regional Police employ a similar practice, known as a “street check” and that any personal information gathered from an individual in a street check can be entered into a database that Peel police maintains.

Scope

The PACER report indicates that from 2009 to 2011, there were 1,104,561 persons entered into the Field Information Report (FIR) database. In 2009 the Vancouver Police Department made 11,507 entries for street checks into the BC PRIME database. In 2012, Andrew Tysowski discovered that while innocent of any crime, the Ottawa Police Service had collected and stored some of his personal information for six years. The Hamilton Police Service published the annual number of street checks its ACTION team completed in its 2013 year-end report to the service's oversight board: 5,423 Street Checks in 2011, 4,803 in 2012 and 3,684 in 2013, records of these activities were recorded in the service's NICHE database. Since 2006, Niagara Regional Police officers have submitted 157,315 street checks. From 2009 to 2014, the Peel Regional Police conducted 159,303 street checks, recorded on PRP17 cards, and a freedom-of-information request by a Peel Region resident revealed that that black people were three times more likely to be stopped than whites. The London Police Service performed 8,400 street checks and entered 14,000 people, vehicles and properties into their database, of those identified, 71% were white, 7.7% were black and 5.3% were of First Nation heritage.
