Sewing thread separability measurement method
1 Scope
This standard specifies the principle, equipment and materials, test conditions and operation of the sewing thread (flat seam) seamability measurement method.
This standard applies to polyester, nylon, vinylon, aramid, cotton sewing thread for sewing apparel, home textile fabrics, cotton wax sewing thread, core seam
For sewing products, etc., sewing thread for other purposes can be referred to.
2 Normative references
The following documents are indispensable for the application of this document. For dated references, only dated versions apply to this article.
Pieces. For undated references, the latest edition (including all amendments) applies to this document.
GB/T 6529 Standard atmosphere for textile commissioning and testing
GB/T 8629-2017 Home washing and drying procedures for textile testing
3 Principle
Sewing thread sewability measurement is carried out on industrial high-speed sewing machine for sewing according to the specified speed, needle number, stitch length, sample and other conditions.
The number of disconnections of a predetermined length is used as a means of expressing the seamability of the sewing thread.
4 equipment and samples
4.1 Equipment. Industrial high-speed sewing machine (single needle).
4.2 Needle. Industrial sewing machine needle.
4.3 The sample specifications shall comply with the specifications of Type B of washing machine type B in GB/T 8629-2017.
5 Test conditions and operation
5.1 Test conditions
The sample and sample shall be conditioned for 24 h according to GB/T 6529, and the sewing test shall be carried out under standard temperature and humidity conditions.
5.2 Sampling
Three samples were randomly sampled per batch.
5.3 Sample preparation
5.3.1 Method 1. Ring sewing test sample preparation
A sample having a length of.200 cm and a width of 10 cm was taken, and six samples were flattened, and the layers were arranged in a staggered manner. Sew the center line first,
Then, a line is sewed equally to the two sides, and finally two side lines are sewn, and five parallel lines are sewed together. Stitched and flattened into a ring, ring joint
According to Figure 1, a horizontal line is drawn with a colored stroke at the joint, and the number of turns is calculated starting from the joint.
