Problems solved by technology

However, this type of core yarn has a large elongation and a low elongation coefficient of 2%, so the cocoon yarn does not wrap around the core yarn and become a combined yarn and separates. Therefore, it is necessary to choose an elongation coefficient of 2% and a specific wettability. Cocoon silk has a high elongation coefficient and a core yarn with high crimping properties, but it is difficult to select such a silk

Embodiment

[0024] Embodiment: As shown in Figures 1 to 5, a hollow bulky silk yarn includes a core 1 and a silk outer layer 2 outside the core 1, and the core 1 is at least partially water-soluble polyvinyl alcohol The hollow part formed after the core filament 7 of the filament 5 dissolves.

[0025] The core part 1 is a fully hollow structure 3 formed after the core filaments 7 composed of water-soluble polyvinyl alcohol filaments 5 are dissolved.

[0026] The core 1 is a partially hollow structure 4 after the dissolution of the core filament 7 composed of a part of the water-soluble polyvinyl alcohol filament 5 and a part of the non-elutable filament 6. At this time, the core 1 contains the remaining non-eluted filament 6. The non-eluting filaments 6 can freely assume a crimped structure under a small restraint load. The non-eluting filaments 6 may be thermoplastic synthetic filaments processed by false twisting, or may be spun filaments.

[0027] In the silk making process of silk, ...

specific Embodiment 1

[0028] Specific embodiment 1: The core of the hollow bulky spun silk is a fully hollow structure, that is, there are no other fibers in the center of the spun silk, and the core filaments before water solubility are all water-soluble polyvinyl alcohol filaments.

[0029] Its production process is:

[0030] (1) First, water-soluble polyvinyl alcohol spinning yarn 50 / 1 (fineness 106.3d) with a melting temperature of 80°C is used as the core filament, and 30 to 31 cocoons with a fineness of 3d (total fineness 93.7d) are used as sheath filaments Carry out the mixing reeling process (denier 200d);

[0031] (2), with 200d*3=600d, S twists 300 times / m to carry out twisting process (total denier 600d) with mixed reeling silk;

[0032] (3), then refining and dyeing process: Utilize jet-type strand dyeing machine, first use enzyme 2g / L, sodium carbonate 5g / L and non-ionic surfactant 1g / L to carry out silk refining, the temperature is 60 ℃, the time is 60 minutes; finally, at a tempera...

specific Embodiment 2

[0033] Specific embodiment two: the core of the hollow bulky spun silk is partly hollow with non-eluted silk (nylon) remaining, that is, before water dissolving, the core silk is a mixed core of water-soluble polyvinyl alcohol silk and nylon elastic silk Silk, silk accounts for 80% in this embodiment, and nylon accounts for 20%.

[0034] Its production process is:

[0035] (1), earlier, water-soluble polyvinyl alcohol yarn 50 / 1 and the nylon elastic yarn S of 15d are twisted 200 times / m to carry out the twisting process of the core yarn (the total denier of the core yarn is 121.3d);

[0036] (2), then the cocoon that the above-mentioned twisted silk process is made and 26 grains of fineness is 3d carries out the mixed reeling process (fineness 200d) as sheath silk;

[0037] Then with the operation of a kind of production process (2) and (3) of embodiment, obtain finished product.

[0038] In the present invention, the outer layer of the core filament containing at least part...

Abstract

The present invention discloses a hollow lofty spun silk and the mixed reeling method thereof. The hollow lofty spun silk comprises a core part and an outer layer outside the core part, and the core part at least comprises part of a middle part formed after core silk which is water-soluble polyvinyl alcohol silk is dissolved out. The mixed reeling method is that: in the silk reeling process of thin silk, a silk through pipe perforating the top and bottom of a silk reeling bath is arranged inside the silk reeling bath; the core silk passes through the silk through pipe; underwater rotor wings rotating alternately and reversely are arranged around the silk through pipe; the underwater rotor wings can cause a reverse water flow alternating slowly, so as to lead cocoon filaments to rotate alternately as well as twine and cover around the core silk. The spun silk of the present invention is lofty and elastic. The novel hollow lofty spun silk can be used to produce tatted goods and knit goods, which have unique elegant luster and hue of the thin silk as well as medium thickness, can be made into outerwear which has the hand feeling with bulkiness and light tactile sensation like wool goods, and also has wrinkle restoring ability as well as dimensional stability.

Description

technical field [0001] The invention relates to a hollow bulky spun silk and a blending method thereof, which is used in the field of outerwear to manufacture spun silk woven fabrics and silk knitted fabrics with bulkiness, light texture and good elasticity. Background technique [0002] The inventor of the present invention, at first applied for the patent No. 87105765.4 in China - "Manufacturing Method of Silk Wrapped Yarn". The production technology of "cocoon wrapping silk" that wraps the cocoon silk evenly around the core silk is made of high cocoon silk wetted in the reeling bath, which is 2% of the core thread. [0003] Thereafter, the inventor of the present invention has applied for a patent in China that the patent number is 91101163.3——"elastic composite yarn and its manufacturing method". Pandex elastic fiber) is given a certain amount of draft, and the elastic yarn put in the core is stretched in this way, which is covered by cocoon silk, and is bonded and drie...
