Embodiment 1

[0007] Soybean fiber pretreatment, raw material moisture regain 9.9% → LA004 type cotton opening and cleaning machine → A186D carding machine, raw material relative humidity 71%, temperature 22°C → A272F drawing frame (three-way drawing frame), cooked Evenness basis weight 9.98g / 5m, moisture regain 7.4%, evenness CV 3.1%→FA402B type roving frame→FA502 type spinning frame→1332MD type winding frame, the relative humidity of the yarn is controlled at 77%. The strength and hairiness of soybean protein spandex core-spun yarn produced by this process are superior to those of traditional ring spinning, and the covering effect is good, meeting the requirements for use.

Embodiment 2

[0009] Soybean fiber pretreatment, raw material moisture regain 10.1%→LA004 type cotton opening and cleaning machine→A186D carding machine, raw material relative humidity 68%, temperature 25℃→A272F drawing frame (three-way drawing frame), cooked and dry Quantitative 10.1g / 5m, moisture regain 7.4%, evenness CV 2.9%→FA402B type roving frame→FA502 type spinning frame→1332MD type winding frame, the relative humidity of the yarn is controlled at 78%. The strength and hairiness of soybean protein spandex core-spun yarn produced by this process are superior to those of traditional ring spinning, and the covering effect is good, meeting the requirements for use.

Abstract

The invention discloses a production technology of a soy protein spandex covering yarn, which is characterized in that: soy fiber can be pre-processed, and the moisture regain of the raw material is 8-12%; a scotching machine is used for scotching; a carding machine is used for carding, the relative humidity of the raw material is 65-75%, and the temperature is 18-26 DEG C; a drawing frame is used for drawing from three ways, the quantity of the drawing silver evenness is 7-12g / 5m, the moisture regain is 7-8%, and the silver evenness CV is 2.5-3.5%; roving and yarn fining are carried out; and spooling is carried out, and the relative humidity of the yarn is 72-83%. The soy protein spandex covering yarn produced by the technology has better leading indicators such as strength, hairiness and the like than the traditional ring spinning; in addition, the yarn has good cladding effect, so as to meet the using requirement.

Description

technical field [0001] The invention relates to a spinning process, in particular to a core-spun yarn production process. Background technique [0002] Soybean protein fiber has many excellent properties: fineness, high single strength, fluffy, soft, moisture-wicking, breathable, natural and soft luster revealing luxury and elegance, and has good skin-friendly and health-care functions. However, due to the smooth surface of the fiber, poor cohesion, and light specific gravity, the short fiber is not easy to form a net, fly, and has static electricity during the spinning process. The strength of bleached soybean fiber is relatively low due to its low oil content, and the above situation is more prominent. Therefore, it is necessary to choose and formulate a reasonable production process to ensure the production of high-quality yarn. In the past production, due to the difficulty of pure spinning 14.5tex, coupled with the covering with spandex yarn, the resulting yarn has mor...
