Embodiment 1

[0037] 1. According to the method of patent CN201610827052.5, PLA bio-based filament is prepared by blending polylactic acid fiber and wool fiber, and the weight ratio of polylactic acid fiber and wool fiber is 20:80.

[0038] 2. The weight percentage of each component in the covered yarn is:

[0039] Nylon stretch yarn 70%

[0040] Metal microwires 3%

[0041] PLA biobased filament 27%.

[0042] 3. Preparation of covered yarn: The outer covered yarn on the hollow spindle tube is unwound from the spindle tube and moves upward through the yarn guide hook together with the core yarn. The spindles rotate together at a high speed under the drive of the spindle belt, which drives the outer covering yarn wound on the spindle tube to rotate together to form the winding of the outer covering yarn to the core yarn to obtain the covering yarn. Wherein, the outer covering yarn includes a first outer covering yarn and a second outer covering yarn, the first outer covering yarn is metal...

[0044] 1. According to the method of patent CN201610827052.5, PLA bio-based filament is prepared by blending polylactic acid fiber and wool fiber, and the weight ratio of polylactic acid fiber and wool fiber is 30:70.

[0045] 2. The weight percentage of each component in the covered yarn is:

[0046] Nylon stretch yarn 65%

[0047] Metal microwires 3%

[0048] PLA biobased filament 32%.

[0049] 3. Preparation of covered yarn: The outer covered yarn on the hollow spindle tube is unwound from the spindle tube and moves upward through the yarn guide hook together with the core yarn. The spindles rotate together at a high speed under the drive of the spindle belt, which drives the outer covering yarn wound on the spindle tube to rotate together to form the winding of the outer covering yarn to the core yarn to obtain the covering yarn.

Embodiment 3

[0051]1. According to the method of patent CN201610827052.5, PLA bio-based filament is prepared by blending polylactic acid fiber and wool fiber, and the weight ratio of polylactic acid fiber and wool fiber is 25:75.

[0052] 2. The weight percentage of each component in the covered yarn is:

[0053] Polyester Stretch Yarn 62%

[0054] Metal microwires 3%

[0055] PLA biobased filament 35%.

[0056] 3. Preparation of covered yarn: The outer covered yarn on the hollow spindle tube is unwound from the spindle tube and moves upward through the yarn guide hook together with the core yarn. The spindles rotate together at a high speed under the drive of the spindle belt, which drives the outer covering yarn wound on the spindle tube to rotate together to form the winding of the outer covering yarn to the core yarn to obtain the covering yarn.

Abstract

The invention discloses polylactic acid bio-based functional wrap yarn for sweaters and a preparation method of the polylactic acid bio-based functional wrap yarn, and relates to the technical field of wrap yarn. The functional wrap yarn for processing sweaters is prepared in the mode that stretch yarn is sequentially wrapped with metal microfilaments and PLA bio-based filaments, the antistatic performance of the sweaters is enhanced by adding the metal microfilaments, and the anti-static performance of the sweaters is improved by adding the PLA bio-based filaments. The problem that the sweater easily generates static electricity is solved; by adding the PLA biomass material, the degradability of the sweater is improved, and the skin-friendly property of the sweater is improved; the heat retention property of the sweater is guaranteed by adding the wool fibers, and meanwhile the processing cost of the sweater is reduced.

Description

Technical field: [0001] The invention relates to the technical field of covered yarns, in particular to a polylactic acid bio-based functional covered yarn for sweaters and a preparation method thereof. Background technique: [0002] PLA filament is a new type of biomass material derived from crops in nature. It uses starch-rich sweet potato, corn and other crops as raw materials. It is fermented to obtain lactic acid, and then processed into polylactic acid fiber. It has rich sources and low cost. , good biocompatibility, biodegradable and so on. Originated in the 1930s, my country achieved initial development in the early 21st century. In the past, the industrial application of polylactic acid was limited to some low-end markets. In recent years, with the innovation and breakthrough of polylactic acid material technology and the industrialization of various types of polylactic acid, the mechanical properties, durability and heat resistance of polylactic acid have been imp...
