Embodiment 1

[0035] Example 1: Recycled cotton (noil) and viscose filament

[0036] By adopting the upper-cover-lower-holder-type three-axis composite spinning method for whiskers of the present invention, the two strands of viscose filaments are spread according to the above-mentioned upper-cover-lower carrier split-spreading method, and then the front roller tongs The mouth is twisted and compounded with the recycled cotton fiber sliver to form a smooth triaxial composite cotton yarn. The specific process parameters are shown in the following table. The spun viscose filament upper cover and lower support clamp and wrap the smooth composite yarn with noil staple fiber sliver, and its hairiness index, twist angle, breaking strength, breaking elongation and yarn The unevenness of strip fineness is listed in the table below. Among them, the spinning yield is very high, all higher than 98.5%, indicating that there is little fiber loss such as flying flowers, chips, and end breaks; the number...

Embodiment 2

[0037] Example 2: Short Hair and Silk

[0038] By adopting the upper cover and lower support type three-axis composite spinning method for whiskers of the present invention, the two strands of silk bundles are spread according to the above-mentioned upper cover and lower support split-split yarn method, and then at the front roller jaws with The short-haired fiber whiskers are twisted and compounded to form a smooth triaxial composite wool yarn. The specific process parameters are shown in the following table. The spun silk upper cover and lower support hold the smooth composite yarn wrapped with short-hair fiber whiskers, and the yarn hairiness index, twist angle, breaking strength, breaking elongation and yarn fineness unevenness See the table below. Among them, the spinning yield is very high, all higher than 98.5%, indicating that there is very little loss of fibers such as flying hair and broken ends; the number of hairiness is also very small, indicating that the finish...

Embodiment 3

[0039] Example 3: Kapok / PTT Filament

[0040] By adopting the upper-cover-lower-holder type three-axis composite spinning method for whiskers of the present invention, the two PTT filament bundles are spread according to the above-mentioned upper-cover-lower-holder split-spreading method, and then spread on the front roller jaws. It is twisted and compounded with kapok fiber strands to form a smooth triaxial composite kapok yarn. The specific process parameters are shown in the following table. The upper cover and lower support of the spun PTT filaments hold the smooth composite yarn wrapped with kapok short fiber whiskers, and the hairiness index, twist angle, breaking strength, breaking elongation and yarn fineness of the yarn are not The uniformity is listed in the table below. Among them, the spinning yield is very high, all higher than 98.5%, indicating that there is little fiber loss such as flying flowers, chips, and end breaks; the number of hairiness is also small, i...

Abstract

The invention relates to a top covering and bottom supporting type three-shafting composite yarn and a spinning method thereof. The composite yarn is of a three-shafting composite spun yarn prepared by using an upper-layer filament and a lower-layer filament to clamp and protect chopped fiber strands, so that the formed filament is of a composite yarn in form of cored layer chopped fiber strands being wound by the filaments. The spinning method comprises the steps of firstly installing a top covering yarn spreader, a bottom supporting yarn spreader and a clustering device on a common fine yarn spinning machine; then spreading two filament clusters by an upper yarn spreading roll and a lower yarn spreading roll into two filament layers, synchronously feeding in a front roller jaw together with chopped fiber strand passing through the clustering device in three-shafting manner, and respectively using the two filament layers to clamp the chopped fiber strands by means of top covering and bottom supporting; and when the two filament layers and the chopped fiber strands come out the front roller jaw, forming composite yarns in form of the chopped fiber strands being wound by the two filament layers under twisting action. The method is applicable to spinning of protective type soft, smooth and high-count composite yarns for ultrashort fibers which are easy to fall crumbs and easy to fly, as well as shorter and weaker reclaimed fibers.

Description

technical field [0001] The invention relates to an upper cover and lower support type triaxial composite yarn, a spinning method of the composite yarn and the application of the spinning method, and belongs to the composite spinning technology of the upper cover and lower support protection type in the field of ring spinning. . Background technique [0002] With the rapid development of the textile industry, short and weak fibers such as noil and noil have increased in the textile processing process; the fibers obtained from recycled textiles have a certain gap in length and strength compared with the original fibers; Some new ultra-short and fragile fibers, such as kapok and down, have begun to be paid attention to and utilized. These short and weak fibers produce yarns with low strength and high hairiness. As a result, this type of short and weak fibers cannot be fully utilized. [0003] However, the composite yarn of filament covered staple fiber can make up for this d...
