[0033] Embodiment 2: Spinning soil seed wool / nylon filament composite yarn

[0034] Select one tube of soil-type wool roving and two tubes of nylon filament to carry out three-axis high-count yarn composite spinning. Soil-type hair short fiber strands 3, then pass through the bundler 6; at the same time, the left nylon filament and the right nylon filament are unwound from the filament tube, and are wound around the left tension wheel 4 and the left tension wheel 4 through the left yarn guide hook 12 respectively. The right yarn guide hook 13 winds around the right tension wheel 5, and then passes through the cluster 6 symmetrically; then the triaxial system of the left nylon filament, the right nylon filament and the short fiber of soil species is synchronously fed into the clamp of the front roller 9 In the mouth, it forms the damming and clamping protection of nylon filaments on both sides of the soil-type hair strips; when the three bundles of fiber strips are output from ...

Embodiment 3

[0035] Embodiment 3: Spinning recycled cashmere / silk composite yarn

[0036] Select one tube of recycled cashmere roving and two tubes of silk to carry out three-axis ultra-fine yarn compound spinning, firstly unwind from the roving tube, and then use cashmere roving to pass through the drafting of rear roller 11 and middle roller 10 to form a loop. Use short cashmere fiber strands, and then pass through the bundler 6; at the same time, the left silk and the right silk are unwound from the filament tube, and are wound around the left tension wheel 4 through the left yarn guide hook 12 and passed through the right yarn guide hook 13 respectively. Wrap around the right tension wheel 5, then pass through the bundler 6 symmetrically; then feed the triaxial system of left silk, right silk and recycled cashmere staple fiber synchronously into the jaws of the front roller 9 to form silk in the recycled cashmere staple Damming and clamping protection on both sides; when the three bund...

Abstract

The invention relates to a three-shafting composite spinning process of a constant-tension double-filament adjoining and twisting triangular zone and application thereof. The process comprises the steps of adopting a double-tension wheel to enable two beams of filaments to synchronize with the three-shafting in a way of adjoining left and right sides of a short fiber whisker strip via constant tension to be fed into a front roller through a beam concentrator; after outputting from a jaw of the front roller, wrapping the two beams of the filaments on the short fiber whisker strip in the twisting triangular zone to form a smooth composite yarn with the short fiber whisker strip wrapped by the double filaments basically in a no self-twisting manner. The process is simple and practical, can efficiently improve spinning efficiency and high branching of fibers with worse spinnability and reduce flying, scraps and fluffs in the spinning process, and is suitable for composite spinning of high-count smooth yarns and superfine yarns of shorter, weaker and ultra-short fibers.

Description

technical field [0001] The invention relates to a three-axis compound spinning method in which equal tension double filaments are close to the twisting triangle area and its application. Background technique [0002] Due to the shortage of fiber resources and petroleum energy, it is inevitable to use existing fiber resources with high efficiency, low consumption, ecology and recycling. Fiber is a kind of resource. A large amount of short fibers will be produced in textile processing, and a large amount of fiber materials will be discarded in textiles after human use. The reason is that these fibers are short or ultra-short, weak or fragile. Traditional spinning thinks that these fibers are difficult to spin or cannot be used at all, let alone high-efficiency, low-consumption, high-quality, ultra-fine spinning. [0003] With the development of modern composite spinning technology, spinning methods and products such as core-spun yarn, wrapping yarn, siro spinning, long / short ...
