Double-filament core-spun yarn production device and production method thereof

Abstract

The invention discloses a double-filament core-wrapped yarn production device and a production method thereof. Left and right roller sleeves are arranged on each row of lower roller shafts, front and rear wire guide assemblies are arranged above the drafting system, and the front drafting roller pairs The output roller pair is set at the front, and a negative pressure gathering system is installed between the two. The upper surface of the negative pressure pipe has front and rear air suction ports. For the same left and right whiskers, the left and right core filaments pass through the inner and outer rollers of the front and rear yarn guide assemblies respectively in an S-shape, and then are pressed by the front roller and then output together with the whiskers, which are first realized by the negative pressure of the rear suction port. The fibers in the sliver gather in parallel to the middle, and then the negative pressure from the front suction port realizes the reversal and aggregation, so that the sliver wraps the core wire for the first time. The silk is wrapped twice to obtain the left and right core-spun yarns, respectively, and the latter two are wrapped and plied into yarns under the action of strong twisting.

Description

technical field [0001] The invention belongs to the technical field of textiles, and relates to a new method of ring spinning, in particular to a production device for double-filament core-spun yarn and a production method thereof. Background technique [0002] With the continuous advancement of the times, people's requirements for clothing materials continue to increase. At present, the textile and clothing industry is in an era of pursuing fashion, diversification and high quality. Therefore, new requirements are put forward for the development of textile raw materials and textile technology. Among them, high-quality, high-performance textiles and clean production and processing have become the main development direction of the modern textile industry and an effective way to improve product grades and added value. With the improvement of modern living standards and the acceleration of the pace of work, the high shape retention and easy care of textiles have become importa...

AI Technical Summary

Problems solved by technology

However, there are still many problems in shape retention of fabrics made of different fiber materials. For example, cotton fabrics are easy to wrinkle when worn, poor flatness after washing and drying, and need to be ironed; Chemical fiber fabrics are easy to arch and keep shape when worn

Many practical problems such as insufficient shape retention, unstable shape retention effect, and difficulty in controlling the environmental protection index of the existing shape retention technology have become serious obstacles to high-quality textiles, and can no longer meet people's needs for high-quality clothing in modern society.
