Problems solved by technology

[0006] At present, there are patents disclosing about the blended yarn of one of pupa protein fiber and bamboo fiber mixed with other one or more fibers. The soft and clean yarn blended with low-torque spinning technology has not yet appeared. In addition, pupa protein fiber and bamboo fiber are mixed with other biomass regenerated fibers through compact spinning, siro compact spinning and twisting. Soft and smooth yarn blended with low torque spinning technology also did not appear

Embodiment 1

[0032] Raw material preparation: pupa protein fiber 1.33dtex×38mm, bamboo fiber 1.33dtex×38mm;

[0033] (1) Spinning

[0034] (1) Spinning specifications

[0035] Pupa protein fiber / bamboo fiber: 50% / 50%

[0036] Yarn: 16.7tex siro compact spun soft smooth yarn

[0037] (2) Cleaning process

[0038] Adoption process: FA002A type plucking machine → SFA035C type mixed cotton opener → FA025 type multi-compartment cotton blender → FA106A type porcupine opener → SFA161 type vibrating cotton feeder → A076F type lapping machine.

[0039] The pupa protein fiber and bamboo fiber are evenly arranged and mixed on the cotton catching machine according to the weight ratio; due to the low moisture regain of the bamboo fiber, in order to prevent electrostatic winding during the production process, the raw materials are pretreated: the loose bag of bamboo fiber is fully and evenly Moisture absorption for 24 hours; in the production process, in order to prevent damage to fibers and reduce...

Embodiment 2

[0050]Raw material preparation: pupa protein fiber 1.33dtex×38mm, bamboo fiber 1.33dtex×38mm;

[0051] Pupa protein fiber / bamboo fiber: 60% / 40%

[0052] Yarn density 14.8tex compact spun smooth yarn

[0053] The raw material and spinning process in the present embodiment are compared with embodiment 1, except not adopting twisted low-torque spinning device, all the others are the same.

[0054] Through various performance tests, compared with Comparative Example 2, the hairiness of the yarn in this embodiment is reduced by 70%, the evenness CV value is reduced by 0.2%, the yarn strength is increased by 10%, and the yarn is smooth.

Embodiment 3

[0056] Raw material preparation: pupa protein fiber 1.33dtex×38mm, bamboo fiber 1.33dtex×38mm;

[0057] Pupa protein fiber / bamboo fiber: 70% / 30%

[0058] Yarn density 9.8tex compact spun soft smooth yarn

[0059] In this embodiment, the raw material and spinning process are the same as in Embodiment 2, on the basis of adding a twisted low-torque spinning device.

[0060] Through various performance tests, compared with Comparative Example 3, the hairiness of the yarn in this embodiment is reduced by 72%, the evenness CV value is reduced by 0.2%, the yarn strength is increased by 12%, the number of kinks is reduced by 28%, and the product is soft and smooth , no torsional stress.

Abstract

The invention provides a biomass regenerated-fiber blended silky yarn and a production method thereof. The biomass regenerated-fiber blended silky yarn is characterized in that blended yarn materials include pupa protein fibers and Levin bamboo fibers. The percentages of the pupa protein fibers and the Levin bamboo fibers, by weight, are 20-80% and 80-20%; the pupa protein fibers contain 18 kinds of amino acids and can fit and benefit skins and are noble in color and luster, and wastes are biodegradable; and the Levin bamboo fibers are high in wet-and-dry strength, are capable of bacteria resistance and bacteriostasis and are comfortable and soft and have silky color and luster, and wastes are biodegradable. One kind or a plurality of kinds of other biodegradable biomass regenerated fibers can be added into the blended yarn, the percentage of the sum of the other fibers by weight is 30-70%, and the percentage of the sum of the pupa protein fibers and the Levin bamboo fibers by weight is 30-70% (each fiber is no less than 15%). By processes of compact spinning and Siro compact spinning and Nu-Torque lower torsion moment spinning technology, the spun yarn is silky, has significant skin-benefit and comfortable functions, and is a novel ideal raw material for weaving woven or knitted superior fabrics.

Description

technical field [0001] The invention relates to a soft and smooth yarn blended with regenerated biomass fibers and a production method thereof, belonging to the field of spinning engineering. Background technique [0002] Under the background of environmental protection and healthy fashion trends, with the enhancement of self-awareness and environmental protection awareness, people pay more and more attention to the development of functional and environmentally friendly new yarns, and use several fiber blends to better play their respective roles. Advantages, new yarns with completely new functions can be produced. [0003] Pupa protein fiber is a kind of protein fiber with stable skin-core structure, which is made by blending silkworm pupa protein and natural cellulose fiber by comprehensive utilization of polymer modification technology, chemical fiber spinning technology and bioengineering technology. The pupal protein fiber is wrapped in the outer layer of the fiber, co...
