Embodiment 1

[0025] to combine Figure 1 to Figure 2 , to describe this embodiment in detail. The one-step production process of ultra-fine nylon and polyester blended filaments involved in this embodiment includes the following steps: S1 slice drying, S2 spinning of nylon 6 part, S3 spinning of polyester POY part, S4 nylon 6 and polyester POY Grid tie and S5 winding.

[0026] Drying of slices in step S1: hot air drying of nylon 6 slices and PET slices in a hot air drying device, so that the moisture content of nylon 6 slices is ≦19×10 -6 , fluctuation value≦5×10 -6 ;The moisture content of PET chips≦25×10 -6 , fluctuation value≦5×10 -6 .

[0027] The level and uniformity of the moisture content of the chips are very important for the production of ultrafine denier fibers. The low and uniform water content can greatly reduce the thermal cracking and oxidative cracking of chips during melting, ensuring smooth production. In actual production, nylon 6 slices should ensure that the moi...

Embodiment 2

[0047] to combine Figure 1 to Figure 2 , to describe this embodiment in detail.

Abstract

The invention discloses a one-step-method production process of an ultra-fine nylon and polyester blended filament yarn. The production process comprises the steps of S1, slice drying, S2, spinning ofa nylon 6 part, S3, spinning of a polyester POY part, S4, netting of nylon 6 and polyester POY and S5, winding. The nylon 6 and the polyester POY enter a blended filament yarn network device througha composite yarn guide hook and are netted by adopting a network nozzle, the network pressure is 1.4-1.6 kg, and the network degree is 40-50 per meter; the adopted nozzle comprises an air inlet, a blended filament yarn channel and an air outlet; the blended filament yarn channel is communicated with the air inlet and the air outlet; the blended filament yarn channel is composed of a curve side anda straight line side. According to the one-step-method production process of the ultra-fine nylon and polyester blended filament yarn, the nylon and polyester blended filament yarn is produced by means of a one-step method, and the surface of the produced blended filament yarn has ultra-fine nylon fibers, so that a prepared fabric has a unique hand feeling and style and can be widely used for imitated silk fabrics and other high-end textiles. Moreover, the produced blended filament yarn is short in process flow and stable in product quality.

Description

technical field [0001] The invention relates to the technical field of mixed fiber yarn production, in particular to a one-step production process of ultrafine nylon and polyester mixed fiber yarn. Background technique [0002] Ultra-fine nylon is the "Nobel" of fibers. It is supplemented by modern production technology and experimental research equipment to extract the most effective and vital fiber essence. It is completely different from the popular fibers in the market and shows a unique style. aesthetic and trendy art style. Just like the dream of a chemist, "there are exteriors that form within, and all interiors form exteriors." Ultra-fine nylon captures the "life force" in the fiber, making it not only antibacterial and deodorizing, but also healthy and warm. It is silky soft against the skin, while benefiting the person applying the product. Ultrafine DPF nylon is the leading product in the field of clothing. For modern clothing, it has entered an era of winning...
