[0002] Quilted fabric is a common home textile fabric. It is usually made by quilting multiple layers of fabric using a sewing machine. It not only has a sense of layering and is beautiful, but also enhances the overall performance of the fabric. In the quilting process of quilted fabric, sewing thread is inevitably needed. The sewing thread mainly includes polyester yarn, cotton yarn, nylon yarn, silk yarn, etc. First, the sewing thread is installed on the sewing machine, and then the multiple layers of fabric are placed on the sewing machine for quilting, and the multiple layers of fabric are combined together to obtain the quilted fabric, and the sewing thread forms a stitch on the quilted fabric. However, in the process of quilting with sewing thread, uneven stitches often occur, resulting in uneven seams, wrinkles and other problems.

[0061] Performance Testing (1) The quilted fabrics obtained in Examples 1-5 and Comparative Examples 1-7 were respectively taken, and the stitch appearance of the quilted fabrics was tested, and the test results are shown in Table 2. At the same time, a blank control group was prepared, and the sewing thread used in the blank control group was polyester yarn, that is, the sewing thread was not treated with a surface treatment agent.

[0062] The stitch appearance test adopts the following method: 10 professionals are selected to evaluate and score the smoothness of the stitches on the surface of the quilted fabric, with a total score of 10. The higher the score, the smoother the stitches.

[0063] (2) The modified sewing threads obtained in step S0 of Examples 1-5 and Comparative Examples 1-7 were respectively taken, and the friction coefficient and friction variation coefficient of the modified sewing threads were tested. The test results are shown in Table 2. At the same time, a blank control group was prepared. The sewing thread used in the blank control group was polyester yarn, that is, the sewing thread was not treated with a surface treatment agent.

[0064] Among them, according to ASTM D3108-2013 "Standard Test Method for Coefficient of Friction of Solid Material Yarn", the friction coefficient and friction variation coefficient of the modified sewing thread were tested. The smaller the friction coefficient, the smoother the surface of the modified sewing thread. The smaller the friction variation coefficient, the better the discreteness of the friction coefficient, that is, the better the uniformity of the surface treatment agent on the sewing thread modification.

Moreover, the smaller the absolute value of the increase in the friction coefficient after 12 months of storage, the better the storage property of the surface treatment agent.

[0067] Table 2 Test results Note: “ / ” means not detected.

[0068] As can be seen from Table 2, the modified sewing thread of the present application has a lower friction coefficient, friction variation coefficient and absolute value of increase in friction coefficient after 12 months of storage. The friction coefficient is 0.14-0.18, the friction variation coefficient is 0.25-0.29, and the absolute value of increase in friction coefficient after 12 months of storage is 0.01-0.02. Not only does the surface treatment agent have the characteristics of storage stability, but also the surface treatment agent has the advantage of good uniformity of modified treatment of the sewing thread. At the same time, the surface of the modified sewing thread is smooth, which reduces friction during quilting and reduces the occurrence of stitch breakage or knotting, making the stitch uniform, smooth and beautiful, and also making the stitch score of the quilted fabric reach 10 points. The stitch is smooth and flat, beautiful and comfortable, meeting market demand.

[0069] Compare Example 1 with Comparative Examples 1-2.

It can be seen that in the quilting process, the size of the surface thread tension and the bottom thread tension has an effect on the smoothness of the stitches, and the surface thread tension is within 100-120g and the bottom thread tension is within 35-45g, which can make the stitches smooth and flat, beautiful and comfortable.

[0070] Compare Example 1 with Comparative Examples 3-4.

It can be seen from this that the friction coefficient and friction variation coefficient of the modified sewing thread can be reduced by treating the sewing thread with the surface treatment agent, and the addition of modified hydrogen-containing silicone oil to dimethyl silicone oil and the interaction between the two can further reduce the friction coefficient and friction variation coefficient, and can also reduce the absolute value of the increase in the friction coefficient after 12 months of storage, so that the surface treatment agent has the advantage of stable storage, and also effectively improves the smoothness of the modified sewing thread, so that the modified sewing thread exhibits better comprehensive performance.
