SN/T 1058.1-2013Test method of colour fastness of textile for import and export. Part 1: Test method of colour fastness to saliva (English PDF)

Foreword

SN/T 1058 "Test for color fastness of textile export" is divided into two parts.

--- Part 1. Test methods for saliva-resistant color fastness;

--- Part 2. resistant to chlorine bleaching and non-chlorine bleach color fastness rapid detection.

This section SN/T 1058 Part 1.

This section drafted in accordance with GB/T 1.1-2009 given rules.

SN/T 1058-2002 "import and export of textiles color fastness to saliva test methods" in this section instead.

This section compared with the SN/T 1058-2002, the main technical changes are as follows.

--- Modify the oven temperature (see 4.1 and 82, 2002 edition of 4.2 and 7.3.);

--- Revised standard adjacent fabric choice (see 43, 2002 version 4.3.);

--- Increasing the standard adjacent fabric of choice (see Table 1);

--- Modifying reagent (see 5.1 and 52, 2002 version 4.5.);

--- Modify the sample preparation (see 6.1 and version 7.2 of 6.2,2002 and 5);

--- Adds analog saliva test solution preparation and storage requirements (see 7.1 and 7.2);

--- Modify the drying requirements (see 8.3,2002 version 7.4);

--- Modify the mode of taxation (see 8.4,2002 version 7.5).

This part of German reference standard DINV53160-1:2002 "Determination of common-user items for color fastness - Part 1. Resistance to artificial saliva sex" and GB/T 6151-1997 "General Textiles Tests for color fastness test." For DINV53160-1. in 2002 we modified the method to Under Content.

--- Test adjacent fabric instead of paper;

--- Increasing the standard cotton lining paste containing liquid was about 150%.

This section proposed and managed by the National Certification and Accreditation Administration Committee.

This section is drafted. Tianjin People's Republic of China Exit Inspection and Quarantine.

4 Equipment and Materials

4.1 Oven. The temperature is maintained at 37 °C ± 2 °C.

4.2 Test equipment. including a stainless steel frame, a set weighing about 5kg, the bottom area of about 11.5cm × 6cm weight (including spring plate), Together with the size of about 11.5cm × 6cm, thickness of glass or acrylic resin plate of 0.15cm, 100m × 4cm combination sample holder in the middle of the plate. Instrument structure should ensure that the sample pressure 12.5kPa.

4.3 standard adjacent fabric. for each combination of sample required two single-fiber adjacent fabrics or over one fiber adjacent fabrics, each size 10cm × 4cm. Such as using a single fiber stickers lining, with the first piece of the same fiber sample is made, the second block by Table 1 provides fiber material.

As the sample is blended or woven goods, the first one with the main content of the fibers, the second block is made of secondary fiber content. Stick lining used Fabric specifications shall comply with GB/T 7568.1 ~ 7568.7 in.
