Embodiment 1

[0030] A silk elastic yarn such as figure 2 As shown, it includes: a central core wire 1 with a central core arranged in a straight line. The core wire 1 is a wire with resilience. The elastic thread is spandex thread. 8 or 16 or 32 or 64 or other numbers of cocoon threads 2 are wound and wrapped on the outer wall of the core thread 1, and the amount of the cocoon threads 2 depends on satisfying the requirements on the outer wall of the core thread 1. The upper part is completely wrapped with the necessary amount of cocoon silk 2. The cocoon threads 2 are parallel to each other, that is, each cocoon thread 2 has the same thread direction.

[0031] The elastic silk yarn is prepared by the following method:

[0032] S1. Select qualified raw material cocoons.

[0033] S2. Carry out cocoon peeling and cocoon selection. After peeling off the cocoons of silkworm cocoons, cocoons are selected, secondary cocoons, waste cocoons and other cocoons that are not suitable for automat...

Embodiment 2

[0039] Based on the elastic silk yarn described in Example 1, the qualified raw material cocoon in step S1 is: a raw material cocoon whose unwinding rate is greater than 70%, the number of hanging times per 10,000 meters is less than 2.5, and the cocoon width uniformity rate is greater than 75%. Using the raw material cocoons of this standard can obtain high-quality elastic silk yarns, reduce the problem of broken cocoon threads during the preparation process, and stabilize the thickness of elastic silk yarns.

Embodiment 3

[0041] Based on the elastic silk yarn described in Example 1, when performing the threading operation described in step S3, the operating temperature is controlled to be 94°C. When carrying out the arranging operation described in step S3, the operating temperature is controlled to be 42°C.

Abstract

The invention provides a silk elastic yarn. The silk elastic yarn aims at solving the detects in the prior art and comprises a middle core yarn with a linearly arranged middle core and elastic resilience; the outer side wall of the middle core yarn are wound and wrapped with eight or more cocoon silks; the eight or more cocoon silks are parallel to each other. The preparation method of the silk elastic yarn comprises the steps that S1, qualified raw material cocoons are selected; S2, cocoon stripping and cocoon selecting are conducted; S3, the silk thread end of a mature cocoon is led out after end groping and end picking are conducted on a mature cocoon, and two or more silk thread ends of mature cocoons adhere to the drawn middle core yarn; S4, the mature cocoon adhering to the middle core yarn is spun, and twisting sheathe operation is conducted on twisted yarns; S5 detection is conducted on the thickness of yarns after twisting sheathe operation is conducted; S6, drying operation is conducted on detected yarns for two times, and the dried yarns are wound on a silk tube, wherein rough fault removing and manual end joining operation are conducted in the tube winding process. According to the silk elastic yarn, the silk elastic yarn is not fractured and can be rebounded when the silk elastic yarn is drawn.

Description

technical field [0001] The invention belongs to the technical field of functional silk preparation, and in particular relates to elastic silk silk and a preparation method thereof. Background technique [0002] Real silk generally refers to the spun yarn prepared by intertwisting cocoon silk, including mulberry silkworm cocoon silk, tussah silkworm cocoon silk, castor silkworm cocoon silk, cassava silk cocoon silk, etc. Silk is known as the "fiber queen", and has been favored by people throughout the ages for its unique charm. Silk is a protein fiber, and silk fibroin contains 18 kinds of amino acids that are beneficial to the human body. Based on the excellent properties of silk, silk is widely used in clothing, bedding and other fields. However, since real silk itself is not elastic, real silk products are prone to problems such as cracking and deformation during use. Therefore, it has become a trend to compound silk and elastic silk. The existing silk elastic yarn str...
