Yarn leakage defect. Yes Knitted fabric For example, yarn leakage is usually caused by the continued operation of the machine after the yarn is disconnected. Missing defects. For knitted fabrics, this situation is that the pattern is damaged by accidental leakage. The reason for this phenomenon may be due to the sticking of the base piece, or the incorrect feeding mode of yarn. Mixed weft defect. This is a visible streak caused by weft yarns different from other normal weft yarns in the fabric.

Spotted blemished. This term is used to describe the appearance of fabrics with many spots. The cause of the spots may be due to the uneven coating on the fabric, or the uneven absorption of pigment from the fabric. Streak defect. For knitted fabrics, this defect is a vertical crack caused by a curved needle. In this case, even though the pattern is not affected, the uniform layout will be deformed. Flower blemished. This situation means that the weft deviates from its regular path and does not intersect with the warp in the place where they should have interlaced, but extends freely over the warp. This defect is most likely to occur within twelve to fifteen inches from the edge of the fabric, and is caused by incorrect setting of the loom.

Pattern defects. Yes woven fabric In this case, the interlacing formation or color embedding is contrary to the fabric pattern design. The reason is that the machine is not working properly, or it may be due to incorrect placement of yarn in the loom thread. For knitted fabrics, the defect is that the formation of the stitches or the insertion of colors are contrary to the pattern design of the fabric. The reason is that the machine is not working properly, or the yarn is not placed correctly on the roving frame.

Defect of needle hole. For fabric that has run over the needle chain stenter, the needle hole is common, but if the needle hole is too far away from the fabric edge, or the needle hole expands and tears, then this fabric defect occurs. Remove defects. For knitted fabrics, this situation means that the fabric is not woven, or the fabric falls from the machine, or the pattern is completely broken and destroyed. Wrinkle faults. This fabric defect refers to the warp deformation caused by the uneven wetting in the process of preshrinking. Generally speaking, it is caused by poor spray head. This defect may show wavy fabric selvage, and may affect any other area of the fabric. When a spray head is used, the wrinkles are usually eight to ten inches wide.

The reed is badly worn. This refers to the fact that one or more warps drawn by a reed are opposite to the pattern design. The reeds are defective. This is a warp streak defect caused by bad reeds. Because the yarn is not evenly distributed, there may be light or heavy stripes on the fabric. In addition, the bad reeds may also cause wear and tear to the yarn and change the dye affinity of the yarn.

Shrinkage and wrinkle defects. Clothing fabric Defect refers to the warp deformation caused by wetting uneven in the process of preshrinking. Generally speaking, it is caused by poor spray head. This defect may appear as wavy fabric selvage, or may affect any other area of the fabric. When a spray head is used, the wrinkles are usually eight to ten inches wide. The shrink cloth is rough. This term is usually used to describe the rough or wrinkled appearance of garment fabrics caused by excessive shrinkage.
