Knit fabric quality inspection standard
First, the source of yarn:
1 Yarn material absorbs better color. Yellow and white yarns are not accepted, and dark (horizontal) lines are not accepted. Cloths such as dead cotton/wool/shells are not accepted.
2 red and blue points; flying flowers; nylon grass; knot; thick section, etc. can not exceed 15 times / 疋. The length must not exceed 0.5cm. Clearable defects must be cleared. Exceeds this limit: Unable to handle the deduction of one-yard full-seal quantity per piece, deducted by corresponding code.
Second, weaving gongs:
1 Do not accept needles, conifers and needles; 2 needles, needles, rotten needles, broken yarns should not exceed 2 yards/inch; 3 embryos should not exceed 2/疋; 4 spandex elasticity The cloth (rack cloth) does not accept the tension of the pulling frame, the unevenness of the pulling frame, the position of the pulling frame, the breaking frame, etc., and cannot exceed 3 yards/inch. 5Not to accept the center mark of the cloth, the crease of the fabric, the scratch of the fabric, the wind mark of the fabric, etc. 6 The embroidered fabric with serious fluffiness is not accepted.
Third, printing and dyeing and related requirements:
1 Do not accept cloth dyed (including strips/clouds/segments), yin and yang, and large pods.
2 Do not accept paragraph or full creases, and do not use color strokes to apply creases. Obvious creases should not exceed 3 yards per trip.
3 It does not accept soft oil stains, floating colors, lip prints, bamboo leaf prints, alkali stains, mildew stains, rust stains (spots), pigment stains (spots), etc.
4 For each piece of cloth, no more than 2 pieces of cuticles or mouths can be removed; stains, oil spots, etc. that can be removed must be removed before handling.
5 The phenomenon of large (bad) hair on the cloth surface is not accepted, and it is required that the cloth surface of the eroded hair be smooth and clean. The repairing cloth should consider the handling of the hair.
6 Grinding brush felt: Do not accept the phenomenon of obvious wear scars, broken yarn, not grinding the edge of the velvet unevenness and other phenomena, antler should be identified with the foot. 7 Printing cloth dyeing can not be dropped soft oil (or selected soft oil designated printing) Printed with the cloth dyeing must choose to use the designated pigments.
8 printing missed (sand bottom) must be repaired before delivery. Cloth with yin and yang color and large enthalpy difference needs to be marked on the delivery note with a corresponding nickname and a mark on the fabric so that the clothing can be cut or positioned according to the corresponding mark.
瑕疵 Inspection rating: According to the United States AATCC international standards or the ten-point system test method.
Fourth, specifications and finishing requirements:
1 practical cloth cover
"Practical Cloth Sealing" refers to the effective width that can be practically used after removing the edge of the pulp or removing the edge of the needle. Open edge setting errors are considered to be acceptable within (-1′′~+1.5′′); (drawing plain cloths are subject to the 12-hour test), and there is no error in the same cloth, otherwise the corresponding ratio Unpaid fabrics (excluding special fabrics such as wick cloths and pits).
2. Unit weight (Gm/m2):
Ordinary open edge setting type error within ± 4%; pull flat plain / unit clothing / beads in the finished product delivery test within ± 5% as qualified (placed 12 hours test).
3. Fabric pattern: 1 The fabric weaves with double-sided tissue, printing, stripes, and plaid fabrics are less than or equal to 3%, which is regarded as qualified (except for the needle-punched two-sided organization). 2 Single-sided tissue cloth, solid-colored cloth, and ribbed cloth ≤ 4%, considered as qualified. When the twist and the slope conflict, the slope is minimized under the precondition of ensuring the twist. 3 bars cyclic error: Any 5 cycle total pitch error is less than 3% pass, any 5 cycle total pitch error between the same cloth is qualified in 2%. 4 Regardless of the straight grained twill, the grain should be straight, and the wavy pattern and the seven-character pattern cannot be accepted. Do not accept blistering on the fabric after setting.
4. Cloth surface and feel: Stained fabric effect, feel effect, etc. are confirmed by both parties. Feel body must be soft and slippery when there is no special requirement to feel!
Fifth, test requirements:
1. The shrinkage rate: The national first-class product quality standard shall prevail.
1 Shrinkage is tested by hanging and drying.
2 Ordinary fabrics shrink within (-5%-±1.5%), and shrink within ((-5.5%-±1.5%)).
3 The fabric must have a twist of ± 4% after washing.
2. Color fastness: The national first-class product qualification standards shall prevail.
1 The color fastness to washing is above grade 4 and dark grade 3.5 or above.
2 Dry rub fastness is lighter than grade 4 and darker than grade 3.5; wet rub fastness is light grade 4 or more, dark 3, rubbing grade 2.5 or more.
3 acid and alkali sweat stain, color fastness in the light color in the 4 above, dark in 3.5 or more.
4 Lightfastness perspiration requires a composite color fastness of 3 or more and sensitive color 3 .
5 as the original color change 4 or more, the same batch of color difference 4, before and after the color difference between the edges, the edge of the color difference of 4 or more, cylinder and cylinder color difference of 4 or more.
3.Environmental protection, acidity and alkalinity: The limitation of formaldehyde content must reach the limit of formaldehyde content ≤20mg/kg specified in national standard GB18401-2003; PH value: 4.0-7.5 (not to exceed the standard).
