example 1

[0031] Example 1: Produced on the TFT-15AS machine produced by TMT in Japan, the POY of 140dtex / 36f is used as the first raw material A, and the POY of 90dtex / 36f is used as the second raw material B. After passing through the 1st wire cutter, the raw material A (140dtex / 36f specification POY) passes through the 2nd first micro-mover, the 3rd first wire feed roller, and the 4th heater (the temperature of the heater is 40-140°C) After stretching 1.5 times and raw material B (POY of 90dtex / 36f specification) passes through the 5th second wire feeding roller with 3% overfeeding, after air blowing and twisting compounding at 6 network nozzles, the surface speed of the third roller / second roller The ratio is 0.97, and the air blowing pressure at the network nozzle 6 is 3.0KG / CM 2 , and then through 7, the third wire feed roller, 8, the first wire guide, and in 9, the first hot box (contact type hot box), the wire strip is stretched and twisted under the heated state, and the temper...

example 2

[0032] Example 2: The false twister that the processed thread enters after passing through the cooling plate 11 is an apron type, and the setting range of the angle of the apron is 90-130 degrees; the setting range of the contact pressure of the apron is 100-300g. Take the 140dtex / 36f POY used in the processing of Example 1 as the first raw material A, and the processing of the 90dtex / 36f POY as the second raw material B as an example. When using the apron type false twister, the apron contact pressure is set at 120g, The angle of the apron is set at 105 degrees.

[0033] Example 3: The first hot box 9 described in Example 1 is a non-contact hot box. The raw material processing used in Example 1 is taken as an example. When using a non-contact hot box, the processing temperature is set to 390 / 370 degrees (the hot box is divided into 2 sections, and 390 / 370 degrees is the temperature of the upper section / lower section).

[0034] Example 4: The temperature of the second hot box...

Abstract

The invention discloses a wool-like composite textured yarn and a manufacturing method thereof. The composite textured yarn is provided with a core-sheath structure, and a core part and a sheath part of the composite textured yarn have different filament length differences and different extents. The manufacturing method is as follows: 2 POYs are taken as raw materials, wherein one POY raw material is heated to be stretched by a heater between a first yarn feeding roller and a second yarn feeding roller, and merged with the second POY raw material in front of the second yarn feeding roller, enters into a network nozzle between the second yarn feeding roller and a third yarn feeding roller by means of certain overfeeding, forms a network through air blowing and twisting, and is heated, stretched and textured to form the composite textured yarn. The prepared yarn has low manufacturing cost; and textile fabrics which are woven by the yarn after twisting have good wool-like effect, soft, dry and comfortable hand feeling and good rebound resilience and color emissivity after being subjected to alkali decrement, and are good fabrics of black formal dresses.

Description

technical field [0001] The invention belongs to a new type of composite deformed yarn, in particular to a wool-like composite deformed filament and its manufacturing method. Background technique [0002] There are many methods of manufacturing wool-like filaments. For example, the one-step method is used to produce wool-like filaments of different fibers, different shapes and shrinkages, and three different polyester wool-like filaments in the spinning process; Get blended filaments to obtain the wool fabric style; also have the publication number as methods such as the composite false twist processing of FDY and POY raw materials mentioned in the patent of CN1940156A. Although the filaments prepared by the above method have different fabric style characteristics, the cost of raw materials or manufacturing cost are relatively high, and the comprehensive effects such as softness, dry feeling and wool-like degree are not ideal enough. Contents of the invention [0003] The ...
