1.5 Details
The workmanship of socks is mainly reflected in the cuff, head, soles and other parts of socks. According to the market investigation, the common problems of similar products are easy to break holes, easy to slip off, poor elasticity, thick seams, seams open easily, easy to drop glue, and so on.
Through continuous research, the solutions to the above problems are as follows.
1.5.1 Easy to Break Holes
Sock toes, soles, heels and other areas prone to holes are reinforced with high-quality nylon yarn to enhance firmness.
1.5.2 Easy to Slip Off
The sock cuffs are made of elastic bands with high-quality lifting strength and elasticity, which will prevent them from slipping or pinching your ankles. If it is single-layer socks, you can apply a layer of non-slip silicone inside the sock opening as needed.
1.5.3 Poor Elasticity
For double-layer socks with fabric uppers, choosing the right size is most important. For double-layer socks with yarn on the surface or single-layer socks, using good quality spandex can enhance the tensile strength and resilience.
1.5.4 Thick Toe Seams
The use of advanced computer sewing machine, coupled with more than 10 years of experience of sewing workers, can make the sock head seams flat, basically no tickling ribs.
1.5.5 Seams Open Easily
The use of high-quality nylon yarn as the suture line at the sock toe and ankle seams can increase the firmness of the seams, and at the same time, no tiny openings are missed when the sock toe is sewn.
1.5.6 Easy to Fall Off
In order to prevent the glue from falling off, we have specially studied the optimal temperature for silicone and PVC to adhere to the yarn, such as acrylic 100-130°C, polyester 120-130°C, cotton 130-150°C. The blended yarns are dominated by lower temperatures in their components.
2.Manufacturing
The process is sampling, knitting, linking, boarding, inspection, packaging, etc.
2.1 Sampling
Before bulk production, we create a technical sheet that contains are the information to produce the desired socks. Sample pairs are produced and sent to client for quality, size, color, drawings and other elements confirmation. We only start production when the samples are approved. If required we can perform test reports.
2.2 Knitting
After the sample is confirmed, we produce the order as per the established specifications and requirements. At present, we have 6 skilled mechanics, 30 experienced knitters, and 80 computerized sock machines, which are equipped with single needle cylinders of different gauges and needles, and can knit various tissues such as plain stitch, plating, tuck, jacquard, terry and horizontal stripes.
2.2.1 Gauges
It mainly includes 4.0-inch and 4.5-inch gauges.
2.2.2 Needles

2.2.4 Jacquard
In addition to the main yarn supply port, there are one or more auxiliary yarn ports that supply yarn at the same time, and use jacquard equipment to control the formation of patterns.
2.3 Linking
At present, it mainly uses two methods to link the head, such as manual cross-stitching and straight blind stitching. There are 6 Rosso machines for straight seams and 3 Lintoe machines for cross-stitch seams.
2.3.1 Straight Blind Stitching
This method uses a straight sewing machine, uses overlock stitching, and wraps the sock toe coil with stitches to produce a relatively flat sock toe.
2.3.2 Manual Cross-Stitching
This method uses a round socks machine, and the stitched socks toe coils are sequentially put on the needle of the sewing machine to sew. The socks toe produced has no ribs.
2.4 Boarding
All socks pass through are boarding machines to give them a clean look and feeling before being packed. There are 1 rotary electric steam boarding machine, which is generally used for setting short socks, and 2 hanging electric steam boarding machines, which are suitable for all types of socks.
