Printing cashmere knitting goods
1 Scope
This Standard specifies the technical requirements, test methods, inspection rules, use
instructions, packaging, transportation and storage of printing cashmere knitting goods.
This Standard applies to combing, carding and semi-worsting pure cashmere knitting
products after printing and cashmere blended knitting goods containing more than 30%
of cashmere.

NOTE 1 Descriptions of appearance defects and appearance defects degrees are specified in Annex
A.
NOTE 2 Minor positions refer to positions where a defect is located and which have small effects, e.g.
the 1/6 place on the left and right of upper garment side seam and sleeve bottom seam, 1/5 of outside
length of trousers under the waist and 1/6 of the left and right of inside rouser seam.
NOTE 3 Refer to similar ratings of defects for the appearance defects not listed in the table.
4 Test method
4.1 Test method for inner quality test is specified in FZ/T 73009. The preset number
of rotations for piling test of semi-worsting products shall be 7 200 r. If sample
photographs are used for rating, the sample photographs of carded knitting goods can
be compared. The test area for bursting strength is 7.3 cm2 (diameter 30.5 mm).
4.2 All requirements for appearance quality test are specified in FZ/T 73009.
5 Inspection rules
5.1 Sampling
5.1.1 A test batch is composed of the same style, the same printed pattern and the
same delivery unit.
5.1.2 Samples for inner quality and appearance quality shall be taken randomly from
a test batch.
Annex A
(Normative)
Descriptions of appearance defects and degrees
A.1 Descriptions of appearance defects
A.1.1 Descriptions of yarn, weaving and sewing defects
Descriptions of yarn, weaving and sewing defects are specified in FZ/T 73009.
A.1.2 Descriptions of printing defects
A.1.2.1 Printing off register (stagger or exposed base). on printed fabrics of two or
more colours, one or more colours of all or part of patterns comes away or coincides.
A.1.2.2 Pattern asymmetry. the positions of symmetrical patterns deviates from a
centre line or some side line.
A.1.2.3 Excessive pattern. pattern or colour printed which should not be printed.
A.1.2.4 Uneven printing of repeats. irregular colour of fabrics caused by uneven
strength applied or uneven plate during printing.
A.1.2.5 Colour smear. pigment paste sticks to or piles up on fabrics.
A.1.2.6 Flushing. outlines of patterns on fabrics are not clear; surroundings of
patterns are rough; colours seeps into each other; patters are blurry or become larger,
not conforming to original patterns.
A.1.2.7 Entire fabric pattern dislocation. during all over printing, pattern edges and
rib edges are not jointed accurately; or patterns are printed at a specified location.
A.1.2.8 Pattern deformation. fabrics are not spread out during printing or garment
blanks are not ironed along the grains before or after printing, so deformation of pattern
is generated.
A.1.2.9 Cross colour. printing colour stains bottom colour or different colours stain
each other.
A.1.2.10 Spot. yellow spots of different areas appear on the unprinted part, as well
as other blotted areas, e.g. colour spots, rusty spots, water spots and greasy spots.
A.2 Descriptions of degrees of appearance defects
