Description of appearance defects
B.1 Uneven segments: Due to the uneven thickness of the short segments of the yarn evenness, the finished product has cloud spots of different shades. B.2 Thick and thin knots: The yarn thickness is uneven, and the large and protruding horizontal strips are formed on the finished product, and they are called thick knots; The small and recessed horizontal strips of the needle loop are thin knots.
B.3 Thick and thin profile: The length of yarn evenness is uneven, and the difference in thickness is too large, which makes the finished product appear obvious thick and thin segments.
B.4 Uneven dyeing: Due to the uneven color absorption of the raw material during dyeing, the finished product has different shades of color.
B.5 Color profile: On the garment piece, due to the different shades of color, the boundary is formed.
B.6 Grass clippings, lint, and flakes: The yarn has impurities such as grass clippings, lint, and flakes that affect the appearance of the product.
B.7 Furry needle: Due to damage or burrs on the needle tongue or the needle shaft, some loops are raised during the knitting process.
B.8 Single wool: In knitting, part of the yarn (less than 1/2) in a loop is unhooked.
B.9 Uneven needles: Due to equipment reasons, larger and slightly protruding coils appear on the finished product. Triangle needle (butterfly needle): In a needle eye, two needle loops overlap to form a triangular small hole on the finished product. Shrinking needles: The pattern on the finished product is not prominent, such as fat flowers not fat, fish scales and so on.
B.10 Uneven needle loop: Due to poor knitting, the finished product has needle loop rungs with different loop sizes and tightness, tight needles, thin or dense loops and so on.
B.11 Inner yarn shows up: In the inter-woven variety, the inner yarn is exposed and reflected on the face. Color mixing is uneven: uneven mixing of fibers of different colors.
