Composite yarn compounded by double yarns through using filament screens to cover downwards and support upwards, spinning method and application

Abstract

The invention relates to a composite yarn compounded by double yarns through using filament screens to cover downwards and support upwards, a spinning method and application thereof. The composite yarn is a double-screen composite yarn with a 3*2 axis formed by clamping and wrapping short fiber yarns through a pair of double filament screens. The composite yarn with three types, consisting of double screen wrapping / double screen wrapping, screen-wrapping screen covering / screen-wrapping screen covering and double screen wrapping / screen-wrapping screen covering, can be woven into textiles and high-grade fine fabrics with clear texture, softness, abrasion resistance, high strength, anti-fluffing anti-pilling property, beautiful appearance and comfortableness. The method for producing the composite yarn comprises the following steps of: arranging a yarn guiding hook and a filament spreading device on a ring spinning frame, dividing four bunches of long filaments into two uplink bunches and two downlink bunches through the filament guiding hook, feeding the uplink bunches and the downlink bunches into respective filament spreader for spreading, forming two paths of covering filament screen and support filament screen, clamping and wrapping the respective short fiber yarns at a twisting triangular region, and compounding to form the double-screen composite yarn. The method provided by the invention is suitable for spinning protective, soft and smooth composite yarns from ultrashort, easily-flaky and easily-flying fibers and shorter and weaker recycled fibers.

Description

technical field [0001] The invention relates to a composite yarn composed of two yarns combined on a screen with an upper cover and a lower holder, a spinning method of the composite yarn, the composite yarn and the application of the spinning method. Background technique [0002] Fiber is a resource that requires land to produce and oil to manufacture. Land is limited and food needs to be grown; oil reserves are dwindling for energy. On the one hand, people have begun to utilize recycled fibers, such as noils and noils in textile processing, and short and weak fibers obtained from the opening of recycled textiles. This is an important way to recycle fibers. On the other hand, some ultra-short and fragile fibers that were originally considered non-spinnable, such as kapok and down, have also begun to be paid attention to and utilized as new fiber resources. However, these short and weak fibers not only have flying flowers, severe shavings and low yield in spinning, but als...

Problems solved by technology

[0006] The above-mentioned related methods, one of them, are spinning for the purpose of changing the yarn style and fancy or high-branching of fibers with excellent spinnability, and fibers with poor spinnability or cannot be spun at all cannot be used; Second, it is more suitable for high-branched and even ultra-high-branched spinning of short and weak fibers
