Embodiment 1

[0029] A far-infrared hollow warm-keeping yarn, the far-infrared hollow warm-keeping yarn is composed of far-infrared hollow polyester fibers with a weight ratio of 80% and viscose fiber blended with 20%, and the specification of the far-infrared hollow polyester fibers is 1.56 dtex×38mm, the specification of the viscose fiber is 1.33dtex×38mm.

[0030] The processing method of far-infrared hollow thermal yarn includes cleaning, carding, drawing, roving, spun yarn and winding processes. Because the two fibers are chemical fibers, they have good uniformity and do not contain impurities, so thermal insulation fibers and Viscose fiber is directly mixed with raw materials in the blowing process according to the yarn forming ratio, and made into laps for production in the subsequent process. Its basic process flow is:

[0031] Far-infrared hollow polyester fiber / viscose fiber: A002C catching machine→A035A mixed cotton opener→A036 cotton opener→A092A cotton box feeder→A076C lapping...

Embodiment 2

[0066] The far-infrared hollow warm-keeping yarn of embodiment 2 is made of the far-infrared hollow polyester fiber of 80% by weight and the viscose fiber blend of 20%. The far-infrared material in the described far-infrared hollow polyester fiber is far-infrared ceramic powder, far The content of infrared ceramic powder is 10% of the total weight of the fiber, 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 is Hollow rate is 30%-40%, all the other are identical with embodiment 1. This embodiment adopts hollow polyester fiber, its heat retention performance and service life are significantly improved compared with Embodiment 1, and its heat retention rate reaches 31.2% in actual measurement, which is slightly improved compared with Embodiment 1.

Embodiment 3

[0068] Both ends of the single hole in the hollow polyester fiber in Example 3 are closed structures, and the length of the closed section is 0.5mm-1mm, and the rest are the same as in Example 2. This embodiment adopts hollow polyester fibers with a single hole and closed ends structure, and its heat retention performance and service life are significantly improved compared with Embodiment 2. The measured heat retention rate reaches 33.6%, which is significantly improved compared with Embodiment 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 thermal yarn and a processing method thereof. Background technique [0002] Traditional winter cold clothing is mostly cotton-padded clothes, cotton-padded overcoats or sweaters plus down jackets and the like, which have the defects of bulkiness, bulkiness, inconvenient movement, and lack of aesthetic feeling. Along with the raising of social development and people's living standard, only relying on the thickness of adding and subtracting clothes to obtain warming effect, can't satisfy people's demand. In the 1990s, the emergence of "thermal underwear" made thermal clothing develop from outerwear to underwear, from the traditional "warm, thick, heavy, and swollen" to "warm, light, thin, and healthy". The warmth of textile and clothing is to block the conduction and convection of human body heat and the outside world. Early thermal underwear mostly ...
