Значение и использование

Fabrics intended for rainwear and all-purpose, water-repellent coat end use should meet all of the requirements listed in Table 1 of this specification.

It should be recognized that fabric can be produced utilizing an almost infinite number of combination of construction variables (for example, type of fibers, percentage of fibers, yarn twist, yarn number, warp and pick count, chemical and mechanical finishes). Additionally, fashion or aesthetics dictate that the ultimate consumer may find acceptable articles made from fabrics that do not conform to all of the requirements in Table 1.

Hence, no single performance specification can possibly apply to all the various fabrics that could be utilized for this end-use.

The uses and significance of particular properties and test methods are discussed in the appropriate sections of the specified test methods.

TABLE 1 Specification Requirements

Note—Grade in colorfastness and DP requirements is based on a numerical scale of 5 for negligible or no color change, color transfer, or fabric wrinkle to 1 for severe color change, color transfer, or fabric wrinkle.

This performance specification covers rainwear and all-purpose water-repellent coat outer fabrics. Fabrics may compose of any textile fiber or mixture of textile fibers. This standard performance is not applicable for fabrics used for linings and interlinings. Fabrics for this purpose shall be tested and meet the following requirements: breaking strength, resistance to yarn slippage, tearing strength, bursting strength, dimensional change, colorfastness, water repellency, water resistance, fabric appearance, and flammability.
