1、 CAN/CGSB-4.2 No. 66-M91 Extended April 1997 Reaffirmed November 2013 National Standard of Canada ICS 59.080.40 Textile test methods Dimensional change and appearance after dry cleaning of coated, bonded, laminated and fused fabrics The CANADIAN GENERAL STANDARDS BOARD (CGSB), under whose auspices t
2、his standard has been developed, is a government agency within Public Works and Government Services Canada. CGSB is engaged in the production of voluntary standards in a wide range of subject areas through the media of standards committees and the consensus process. The standards committees are comp
3、osed of representatives of relevant interests including producers, consumers and other users, retailers, governments, educational institutions, technical, professional and trade societies, and research and testing organizations. Any given standard is developed on the consensus of views expressed by
4、such representatives. CGSB has been accredited by the Standards Council of Canada as a national standards-development organization. The standards that it develops and offers as National Standards of Canada conform to the criteria and procedures established for this purpose by the Standards Council o
5、f Canada. In addition to standards it publishes as National Standards of Canada, CGSB produces standards to meet particular needs, in response to requests from a variety of sources in both the public and private sectors. Both CGSB standards and CGSB national standards are developed in conformance wi
6、th the policies described in the CGSB Policy and Procedures Manual for the Development and Maintenance of Standards. CGSB standards are subject to review and revision to ensure that they keep abreast of technological progress. CGSB will initiate the review of this standard within five years of the d
7、ate of publication. Suggestions for their improvement, which are always welcome, should be brought to the notice of the standards committees concerned. Changes to standards are issued either as separate amendment sheets or in new editions of standards. An up-to-date listing of CGSB standards, includ
8、ing details on latest issues and amendments, and ordering instructions, is found in the CGSB Catalogue at our Web site www.tpsgc-pwgsc.gc.ca/ ongc-cgsb along with more information about CGSB products and services. Although the intended primary application of this standard is stated in its Scope, it
9、is important to note that it remains the responsibility of the users of the standard to judge its suitability for their particular purpose. The testing and evaluation of a product against this standard may require the use of materials and/or equipment that could be hazardous. This document does not
10、purport to address all the safety aspects associated with its use. Anyone using this standard has the responsibility to consult the appropriate authorities and to establish appropriate health and safety practices in conjunction with any applicable regulatory requirements prior to its use. CGSB neith
11、er assumes nor accepts any responsibility for any injury or damage that may occur during or as the result of tests, wherever performed. Attention is drawn to the possibility that some of the elements of this Canadian standard may be the subject of patent rights. CGSB shall not be held responsible fo
12、r identifying any or all such patent rights. Users of this standard are expressly advised that determination of the validity of any such patent rights is entirely their own responsibility.

13、 Canadian General Standards Board Gatineau, Canada K1A 1G6 The Standards Council of Canada (SCC) is the coordinating body of the Canadian standardization network, which is composed of people and organizations involved in the development, promotion and implementation of standards. Through the collabo
14、rative efforts of Canadian standardization network members, standardization is helping to advance the social and economic well-being of Canada and to safeguard the health and safety of Canadians. The networks efforts are overseen by SCC. The principal objectives of SCC are to foster and promote volu
15、ntary standardization as a means of advancing the national economy, supporting sustainable development, benefiting the health, safety and welfare of workers and the public, assisting and protecting the consumer, facilitating domestic and international trade, and furthering international cooperation
16、in relation to standardization. An important facet of the Canadian standards development system is the use of the following principles: consensus; equal access and effective participation by concerned interests; respect for diverse interests and identification of those who should be afforded access
17、to provide the needed balance of interests; mechanism for dispute resolution; openness and transparency; open access by interested parties to the procedures guiding the standards development process; clarity with respect to the processes; and Canadian interest consideration as the initial basis for
18、the development of standards. A National Standard of Canada (NSC) is a standard prepared or reviewed by an SCC-accredited SDO and approved by the SCC according to NSC approval requirements. Approval does not refer to the technical content of the standard, as this remains the responsibility of the SD
19、O. An NSC reflects a consensus of a number of capable individuals whose collective interests provide, to the greatest practicable extent, a balance of representation of general interests, producers, regulators, users (including consumers) and others with relevant interests, as may be appropriate to
20、the subject at hand. NSCs are intended to make a significant and timely contribution to the Canadian interest. Those who have a need to apply standards are encouraged to use NSCs. These standards are subject to periodic review. Users of NSCs are cautioned to obtain the latest edition from the SDO th
21、at publishes the standard. The responsibility for approving standards as NSCs rests with: Standards Council of Canada 270 Albert Street, Suite 200 Ottawa, Ontario K1P 6N7, CANADA How to order Publications: by telephone 819-956-0425 or 1-800-665-2472 by fax 819-956-5740 by mail CGSB Sales Centre Gati

32、 5.1 5.1.1 5.1.2 5.1.3 5.1.4 5.2 5.3 5.4 5.4.1 5.5 Crack mark: in coated, bonded, fused, or laminated fabrics, a sharp break or crease in the surface contour of either the face fabric or the backing fabric that becomes evident when the coated, bonded, fused, or laminated composite is roiled, bent, d
33、raped, or folded. Fused fabric: a type of bonded fabric made by adhering a fusible fabric to another fabric, such as for use as an interlining. Laminated fabric: a layered fabric structure wherein a face or outer fabric is joined to a continuous sheet material, such as polyurethane foam, in such a w
34、ay that the identity of the continuous sheet material is retained, either by the flame method or by an adhesive, and this in turn normally but not always, is joined on the back with a backing fabric such as tricot. Pills: bunches or balls of tangled fibres which are held to the surface of a fabric b
35、y one or more fibres. Puckering: in coated, bonded, fused, or laminated fabrics, a wavy, three-dimensional effect typified by closely spaced wrinkles, on either the face fabric or the backing fabric or both. Solvent relative humidity: the humidity of air over a dry cleaning bath in equilibrium with
36、the solvent and its smali amount of water. Every dry cleaning solvent bath containing detergent can require a different absolute water content to reach the U.S. Federal Trade Commission (FTC) specified level of solvent relative humidity for a normal dry cleaning (Note 1). The actual solvent relative
37、 humidity in the air over a solvent must be measured by an hygrometer after equilibrium has been reached between the water content of air and the solvent. Wrinkle: an objectionable crease, generally short and irregular in shape. APPARATUS AND REAGENTS Dry cleaning machine: a single unit coin-operate
38、d type machine, with rotating cage, totally enclosed and capable of providing a completely automatic dry-to-dry cycle using tetrachloroethylene (perchloroethylene). The diameter of the rotating cage shall not be less than 600 mm and not more than 1080 mm. The depth of the cage shaii not be less than
39、 300 mm. The machine shail be fitted with two to four lifters. The machine shall be equipped with thermometers for measuring the solvent temperature and the air drying temperature. The speed shall be regulated to give a g-factor of 0.5 to 0.9 for cleaning and 35 to 120 for exraction (Note 2). Sewing
40、 machine: suitable for sewing a single row of stitching 25 mm from the edge of the specimen, for example using 25 tex mercerized cotton thread. Metal template: with a 250 mm square opening, for marking out the specimen. Measuring scale: graduated in millimetres. A premarked device calibrated to give
41、 the percentage of shrinkage or growth can also be used. Steam press: a press approximately 600 x 1250 mm or larger, provided with 410 to 490 kPa steam pressure at the press. Any steam press large enough for pressing 400 mm square specimens may be used. Note 1: Information is available from Superint
42、endent of Documents, US. Government Printing Ofice, Washington, DC 20402, USA. Nok 2: The g-factor is calculaed as follows: g = SS9n2di10 O00 O00 where: n = revolutions per minute d = cage diameter, mm 2 NO. 66-M91 5.6 5.7 5.8 5.9 5.10 5.11 6. 6.1 6.2 8 6.3 6.4 6.5 7. 7.1 8. 8.1 8.2 8.3 8.3.1 8.3.2
43、8.4 Lighting equipment: for viewing test specimens, as described in Figure 1 of CANKGSB-4.2 No. 59.1-M. Solvent: tetrachloroethylene (perchloroethylene) commercial grade. Dry cleaning detergent: petroleum sulphonate or amino sulphonate type. Scissors. Dummy load: 400 x 400 mm pieces of fabric simila
44、r to that being tested. Hygrometer, TEST SPECIMENS Condition the samples in accordance with CAN/CGSB-4.2 No. 2-M. Cut two specimens 400 x 400 mm from each sample, one located approximz :ly 1/3 the distance of the width of the fabric from one side and the other located approximately 1/3 the distance
45、of the width of the fabric from the other side. Mark the warp (wale or machine) direction of the specimen. Sew a straight row of stitching around each specimen, 25 mm from the edge. Using an indelible fine-line marker, mark a 250 x 250 mm reference squm, centrally located on the face of each specime
46、n. Apply three sets of reference markings 250 f 2 mm apart in the direction of the fabric length. Locate the markings within 25 mm of each end and at the midpoint of each side of the square. Similarly, apply three sets of markings in the direction of the fabric width (Note 3). Retain the remainder o
47、f the sample for comparison with the dry-cleaned test specimen. SOLVENT PREPARATION Prepare a standard detergenudry cleaning solvent mixture by adding sufficient detergent to the solvent to make a 1% volume/volume solution. Add sufficient water to the solution to give a solvent relative humidity lev
48、el of 75% for the particular dry cleaning detergent used. Put this solvent in the machine storage tank. The same solution can be used for repeated cleanings until it becomes dirty as long as the solvent relative humidity is adjusted before each run. PROCEDURE Condition the dummy load for at least 4
49、h in the standard atmosphere in accordance with CAN/CGSB-4.2 No. 2-M. Following the dry cleaning operation, condition the load again before each additional dry cleaning cycle (Note 4). Place the test specimens and sufficient dummy load to give a total mass of 3.6 kg in the dry cleaning machine. Run the load through the complete dry-to-dry cycle in the machine. Run the solvent phase of the dry cleaning with the solvent temperature no higher than 32C. During the drying phase of the cycle, the outlet air temperature shall not exceed 60C and the inlet air
