Embodiment 1

[0088] Embodiment 1: Recycling the composite yarn of cotton / viscose filament asymmetric net-wrapped core-spun yarn

[0089] Adopt the compound spinning method that is used for double-bundle network symmetric composite yarn of the present invention, get two bundles of viscose long filaments and be divided into left tow 12L and left mesh tow 13L and linear density that are not equal in linear density The right wire bundle 12R and the right mesh wire bundle 13R. Left tow 12L after splitting and right tow 12R are adjusted its tension through left tension disc 31L and right tension disc 31R respectively and through left upper line guide wire hook 32L and right upper line guide wire hook 32R to adjust left tension disc 31L and right Surrounding angle θ of tension disc 31R L and enveloping angle θ R The tension of the left tension disc 31L to the left tow 12L is less than the tension of the right tension disc 31R to the right tow 12R, through the left downward guide wire hook 37L a...

[0090] Embodiment 2: cashmere / silk filament asymmetrical net wrapped close to the composite yarn of the yarn

[0091] Using the compound spinning method for double-bundle mesh symmetrical composite yarn of the present invention, take two bundles of silk and split them into left tow 12L with unequal linear density, left mesh tow 13L and right tow 12R with unequal linear density With right mesh tow 13R. Adjust the tension of the split left tow 12L and right tow 12R through the left tension disc 31L and the right tension disc 31R and adjust the tension of the left tension disc 31L and the right through the left upper guide wire hook 32L and the right upper guide wire hook 32R Surrounding angle θ of disk 31R L and enveloping angle θ R The tension of the left tension disc 31L to the left tow 12L is equal to the tension of the right tension disc 31R to the right tow 12R, and the left upper guide wire hook 35L and the right upper guide wire hook 35R are fed in close to the front uppe...

Abstract

The invention relates to double-bundle screen asymmetric composite yarn, a composite spinning method and applications. The composite yarn is of 3*2 double-bundle screen composite yarn by carrying out 2-shafting symmetrical compounding to silk frock / chopped fiber / silk screen 3-shafting symmetrical screen-wrapped core-spun yarns, silk frock / chopped fiber / silk screen 3-shafting symmetrical screen-wrapped abut yarns, or silk frock / chopped fiber / silk screen 3-shafting symmetrical screen-wrapped fascinated yarns, and can be used for weaving fabric and fine high-grade fabric, which have clear textures, are soft and wear-resistant, high in strength and pilling-proof and attractive and comfortable. The spinning method for realizing the composite yarn comprises the steps of splitting two filaments into four bundles by a splitter, wherein two bundles are fed in with equal to unequal tension by a manner of being centered, abutted, or left from chopped fiber strands; the other two bundles are spread by a filament spreader into silk screens, and are fed in by a manner of bottom supporting, top covering or leaving the chopped fiber strands; clamping the chopped fiber strands in pairs to be wound into yarns, and then symmetrically compounding and twisting into yarns. 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 a double-bundle net asymmetric composite yarn, the spinning method of the composite yarn, the composite yarn and the application of the spinning method, which belong to the 3× 2 Asymmetric composite spinning technology. Background technique [0002] As renewable fiber resources and recycled fibers are used as raw materials for textile processing, because these two types of fiber resources are characterized by short length, damaged strength and low strength, the processed products have more hairiness, poor wear resistance and low quality. . As a result, short and weak fibers of this type cannot be fully utilized. The patent provides a composite yarn with filaments covering short fibers, which can make up for this deficiency and improve the utilization rate of short fibers. First of all, it is necessary to solve the separation of filament bundles into single filaments, which has become the prerequisite for composite spinning o...
