Embodiment 1

[0029] A far-infrared hollow thermal insulation yarn, said far-infrared hollow thermal insulation yarn is composed of a blend of 80% by weight far-infrared hollow polyester fiber and 20% viscose fiber, and the specification of the far-infrared hollow polyester fiber is 1.56 dtex×38mm, the specification of the viscose fiber is 1.33dtex×38mm.

[0030] The processing method of far-infrared hollow warm yarn includes cleaning, carding, drawing, roving, spun yarn and winding process. Because both fibers are chemical fibers, they have good uniformity and do not contain impurities. The viscose fiber is directly mixed with raw materials in the blowing process according to the yarn ratio, and made into cotton rolls for later production use. The basic technological process is:

[0031] Far-infrared hollow polyester fiber / viscose fiber: A002C grabbing machine → A035A mixed opener → A036 opener → A092A box feeder → A076C roll machine → A186C carding machine → FA311F draw frame (two-pass )→FA4...

Embodiment 2

[0066] The far-infrared hollow warm yarn of Example 2 is composed of a blend of 80% by weight far-infrared hollow polyester fiber and 20% viscose fiber. The far-infrared material in the far-infrared hollow polyester fiber is far-infrared ceramic powder. The content of infrared ceramic powder is 10% of the total fiber weight, and the far-infrared radiation wavelength of the far-infrared ceramic powder is 4 μm-14 μm; the far-infrared hollow polyester fiber is a single-hole hollow polyester fiber, and the average value of the single-hole hollow polyester fiber The hollow rate is 30%-40%, and the rest is the same as in Example 1. In this embodiment, hollow polyester fiber is used, and its heat retention performance and service life are significantly improved compared to Example 1. The measured heat retention rate reaches 31.2%, which is slightly improved compared with Example 1.

Embodiment 3

[0068] The two ends of the single hole in the hollow polyester fiber of Example 3 are closed structures, and the length of the closed section is 0.5 mm-1 mm, and the rest is the same as Example 2. This embodiment uses a hollow polyester fiber with a single-hole and closed-end structure, and its warmth retention performance and service life are significantly improved compared with Example 2, and its warmth retention rate is measured to reach 33.6%, which is significantly improved compared with Example 2.

Abstract

The invention discloses far infrared hollow thermal yarns and a processing method. The far infrared hollow thermal yarns are processed by blending 75 to 85 weight percent of far infrared hollow polyester fibers and 15 to 25 weight percent of viscose fibers. The processing method comprises procedures of blowing, carding, drawing, roving, spinning and spooling. According to the far infrared hollow thermal yarns and the processing method, the problems of heaviness, poor air permeability, inconvenience for movement and lack of beauty of thermal garments in the prior art are effectively solved; a garment fabric woven from the yarns is high in thermal insulation property, light, air-permeable, comfortable and long in service life, and has high practical value.

Description

Technical field [0001] The invention relates to the technical field of textile fabrics, in particular to a far-infrared hollow warmth-keeping yarn and a processing method thereof. Background technique [0002] Traditional winter warm clothing is mostly cotton clothes, cotton coats or sweaters plus down jackets and other outer clothing, which are bulky, bloated, inconvenient to move, and lack aesthetics. With the development of society and the improvement of people's living standards, simply adding or subtracting the thickness of clothing to obtain warmth can no longer meet people's needs. In the 1990s, the emergence of "thermal underwear" made the development of thermal clothing from outerwear to underwear, from the traditional "warm, thick, heavy, and swollen" to "warm, light, thin and healthy". The warmth of textiles and clothing is to block the conduction and convection of human body heat and the outside world. Early thermal underwear mostly used sandwich filling methods to ...
