Embodiment Construction

[0012] The processing of the present invention is described in detail below.

[0013] a. Initial twist: Twist the monofilament of the original yarn, the twist is 600-800 twist / m, and the twist direction can be S twist (or Z twist); twist the monofilament to make the yarn firm and increase the toughness , the S-twisting or Z-twisting here are two kinds of twisting methods with opposite twisting directions commonly known in this industry. If the S-twisting is clockwise, then the Z-twisting is counterclockwise. As you can see below, each process The twisting direction is just opposite;

[0014] b. Parallel twisting: Merge the twisted monofilaments into one multi-strand yarn, and then parallel twist, the twist is 340-350 twists / m, and the twist direction during parallel twisting is opposite to that of initial twisting, that is, the initial twist When S twist (or Z twist), the parallel twist should be Z twist (or S twist). If the monofilament is not combined into a multi-strand th...

Abstract

The invention discloses a spring yarn and producing method relating to yarn of braiding lace, which is characterized by the following: the yarn presents spiral spring state, which possesses cooling duct forming from spiral winding; the method comprises of a, first twist, b, cabling, c, hard twist, d, shape, e, modeling; the spring possesses high elasticity, which can bulk automatically after braiding lace.

Description

technical field [0001] The invention relates to a yarn for weaving lace, especially a yarn with good elasticity. Background technique [0002] In the prior art, the yarn used for embroidery is mostly a straight yarn, and the pattern embroidered by this yarn is basically planar, and the three-dimensional effect is relatively poor. Contents of the invention [0003] The purpose of the present invention is to provide a kind of spring yarn and its production method. The spring yarn is helical and has high elasticity. After being woven into lace, it will automatically fluff up and form a strong three-dimensional effect. [0004] According to the design solution provided by the present invention, the yarn is in the shape of a helical spring, and has a hollow channel formed by helical winding in the middle. [0005] The production method of this spring yarn includes: [0006] a. Initial twist: perform initial twist on the monofilament, the twist is 600-800 twist / m, and the twis...
