This standard specifies a method for determining the dimensional change (shrinkage or elongation) of various woven fabrics after commercial laundering near the boiling point. This standard is mainly used to determine cotton fabrics. If used for other fabrics such as linen, regenerated cellulose fibers, refer to Chapter 9g). This method is only used to evaluate the dimensional change of woven fabrics after a single laundering. When this method is used to measure the incremental value of dimensional change, the sample must be washed repeatedly, and the total dimensional change value of the sample after the cyclic washing compared with the original size of the sample before washing, as well as the number of cyclic washings, must be clearly stated in the report.

ISO Foreword
ISO (International Organization for Standardization) is an international federation of international standard organizations (ISO member organizations). The work of formulating international standards is carried out through ISO technical committees: each member body has the right to be represented in the technical committees established by ISO. Parties and non-official international organizations with ties to ISO may participate in the work. International standards adopted by ISO committees are distributed to all member countries according to the rules before they become international standards. ISO standard TS01675 was prepared by TS0/TC.38 Technical Committee on Textiles: According to Article 6 of the TS working instructions, this standard has been submitted directly to ISO Council.

This standard specifies the determination of the change in size (in the direction of shrinkage or elongation) of selected woven fabrics after commercial washing and ironing. It is used to determine the change in size of new cotton fabrics, such as cotton, recycled red fiber and other single materials. The method is only suitable for evaluating the change in size of woven fabrics. When this method is used to measure the change in size, the sample should be washed repeatedly and the total change in size after the sample is compared with the original size of the sample before washing should be clearly stated in the report. The number of changes after washing is calculated.

wash the sample in a washing machine under certain conditions. After washing, remove excess water, do not care about drying but directly put it in a flat ironing machine, and measure the distance between the warp and the mark of the sample after washing. 4 Reagents

The clothes delivery machine has thermal energy. If it is suitable to press steam heating, the full gas is converted into electric heating, and the degree of water is large enough to ensure that the T The internal fire exhaust
controller should have a wet bottom meter that can display the water temperature during washing, and a water level indicator should be provided outside the machine to indicate the water level inside the machine.
When loading the machine, it should be determined according to the size of the machine, including the volume of the lifting piece. The amount of water used for each cubic meter of the load should be appropriate, and the total water content should be 2-1 (with the rate as the degree) with the internal diameter of the machine.
Use a porous transfer washing and swelling type centrifugal dehydrator to form a virtual device. The moisture content of the fabric after water is controlled within %~1 head, and the moisture content of the fabric can be controlled within 1%. It can resist the same effect as described above without producing or producing empty shapes. The uniqueness of the glue-drying machine is that it can pass through two lines without causing any inefficiency:

6 Sample preparation
The test sample should be full width and less saturation. The sample should be taken from the upper side of the test specimen and not be withdrawn. The edge of the test bar should be parallel to the direction of the material. Do not collect samples within 1m of the fabric coupon. It is better to collect samples within 3m of the right end. Mark the samples according to 6.2~5. of (H/328-2001.7.1.1 Put the fast or multi-effect machine into the washing machine and add enough similar fabrics as specified (see 5.1). Start the machine and start the timing. The machine should run continuously for a period of time. 7.1.2 Pour water (see 1.2) into the machine and call it to the appropriate wash water level (5.0 g) within 1 min. After the water starts to rise, add it to the full point within 1 min.

Calculation and expression of results
Calculate half of the change in size of the specimen in warp and weft directions respectively, and express it as the average percentage of the size change to the size before the test: 0.1. Use the positive sign (-) to indicate shrinkage, and the positive sign (+) to indicate elongation. Calculate the range of size change between the same specimens in warp direction:
9 Test report
The test report contains the following contents:
: The test is carried out in reverse order according to the standard; b! The number of cycles subjected to the test;
) Each specimen is read upwards and the size change is recorded between the sources, and expressed as the percentage of the size before the test: d: The range and average value of size change between the same specimens in warp direction.) Test code includes selvedge:
E! The amount of soap used is still 3g/. When the reason is clear:) The method of using soap to stretch the fabric is easy to stretch. The following statement is made: "In commercial washing, the use of evenly distributed and heavy tension may cause the fabric to be washed very effectively. G/T8632-2001
