AI Technical Summary

Problems solved by technology

Siro spinning and cable spinning are two strand production methods that can be realized on the spinning frame. Among them, Siro spinning can produce yarns similar to double-ply yarns, but the existing cable spinning uses a single roving to feed, and is equipped with a split The roller completes the division of the drawn strands to form strands. The existing problems are: 1. The width of the strands is small, and it is difficult to divide; Stable, changes between 3-5 strands, cannot be precisely controlled, and affects the uniformity of evenness; the number of fiber strands on long segments will change, which will eventually lead to uneven yarn structure and unstable performance

Embodiment 1

[0031] One-step precision-controlled strand spinning method, including the following steps:

[0032] 1 piece of white cotton roving 4.8g / 10m, 1 piece of red cotton roving 4.8g / 10m are fed into the roller assembly from the first bell mouth 3 and the second bell mouth 4 respectively, and pass through the first roller assembly 5 and the second roller assembly in turn 6. The 14.3 times of drafting and compacting of the rollers of the third roller assembly 7 and the top rollers form the gripped strands, which pass through the four-groove splitting rollers 12, are divided into 4 strands of fiber strips and pass through the first The 75D white polyester filaments of the filament guide 9 and the 75D white spandex filaments of the second filament guide 11 are jointly twisted by the high-speed rotating spindle 14 to form 7S 4 strands of cotton / polyester / spandex The core-spun yarn is covered and wound to form a bobbin.

Embodiment 2

[0034] One-step precision-controlled strand spinning method, including the following steps:

[0035] 1 piece of blue cotton roving 4.8 g / 10m, 1 piece of red polyester roving 4.8 g / 10m are fed into the roller assembly from the first bell mouth 3 and the second bell mouth 4 respectively, and pass through the first roller assembly 5 and the second roller in turn Component 6, the roller of the third roller assembly 7 and the 12.7 times of drafting and compression of the rollers of the third roller assembly 7 form the strands that are held. The 75D white polyester filament of a filament guide 9 is driven by the high-speed rotating spindle 14 to twist together to form a 7S 4-strand cotton / polyester core-spun yarn, and is wound to form a bobbin.

Embodiment 3

[0037] One-step precision-controlled strand spinning method, including the following steps:

[0038] 1 piece of white cotton roving 4.8 g / 10m, 1 piece of blue viscose roving 4.8 g / 10m are fed into the roller assembly from the first bell mouth 3 and the second bell mouth 4 respectively, and pass through the first roller assembly 5 and the second Roller assembly 6, the roller of the 3rd roller assembly 7 and the 11.4 times of drafting of top roller and form the strand of holding after compacting, this strand passes through four-groove splitting roller 12, is divided into 4 strands of fiber strips by high speed after The rotating spindle 14 drives the mixed-color ply yarn that is twisted together by 4 strands and twisted 7S, and is wound to form a bobbin. The stranding twist of the yarn is a mechanical twist, and the twist of each single strand is 1 / 4 of the mechanical twist.

Abstract

The invention belongs to the technical field of spinning, and particularly relates to a plied yarn production device capable of accurately controlling strands through a one-step method and a spinningmethod. The plied yarn production device capable of accurately controlling the strands through the one-step method comprises a roller assembly, the inlet end of the roller assembly is provided with ahorn mouth used for bundling rough yarns, the outlet end of the roller assembly is provided with strand dividing rollers, and the dividing rollers are provided with grooves used for precisely dividingplied yarns. According to the plied yarn production device capable of accurately controlling the strands through the one-step method and the spinning method, double rough yarn feeding is adopted, sothat the consistency of the width and the thickness of divided fiber strands are effectively improved, and the uniformity and the controllability of dividing each fiber strand are improved; a double-filament feeding mechanism is adopted, through the process of strand dividing and then twisting the plied yarns, the coating property of the core filament is increased, and the coating effect of the coated filament is improved; and precise strand dividing rollers is adopted, accurate control over the number of finished yarn strands is achieved, the diameters of bearings of all kinds of strand dividing rollers are kept consistent, and replacement is flexible and convenient.

Description

technical field [0001] The invention belongs to the technical field of spinning, and in particular relates to a strand production device and spinning method with precise footwork control. Background technique [0002] As an important intermediate product in the textile industry, yarn is an important node and key product in the textile processing process. It is also an important node and key product in the textile processing process. core technologies and key common technologies. The textile industry is an important pillar industry and the people's livelihood industry in our country. my country has become a large textile country in the world, and the total amount of fiber processing accounts for more than 40% of the world. With the improvement of people's living standards and quality, the demand for new varieties, differentiated, differentiated and eco-friendly yarns is also increasing. Among them, eco-friendly yarn is not only a requirement for the production process of ra...
