Embodiment 1

[0040] Manufacture temperature-adjusted cashmere yarn for underwear, the product count is designed to be 18tex.

[0041] Raw material selection: the fineness of temperature-adjusting fiber is 1.7dtex, and the length is 38mm; the fineness of modal fiber is 1.7dtex, and the length is 40mm; the fineness of cashmere is 14.8um, and the length is 38mm. The mass blending ratio of the three fibers is 40:30:30.

[0042] process such as figure 1 shown.

[0043] Raw material preparation: antistatic treatment of 40% of heat storage and temperature regulating fibers with special spinning auxiliary for heat storage and temperature regulation. The auxiliary agent is prepared by antistatic agent, smoothing agent and water in a ratio of 2:8:90 , the PH value is 6, and the addition amount of the spinning auxiliary agent is 5% of the mass of the blended fiber. Spray evenly on the surface of the heat storage and temperature regulating fiber, the treatment requires the moisture regain of the fi...

Embodiment 2

[0055] The temperature-adjusted cashmere yarn used in the manufacture of T-shirts is designed to be 24tex.

[0056] Raw material selection: the fineness of temperature-adjusting fiber is 1.7dtex, and the length is 38mm; the fineness of polyester fiber is 1.8dtex, and the length is 40mm; the fineness of cashmere is 14.8um, and the length is 40mm. The blend ratio is 40 / 20 / 40.

[0057] Technological process: the temperature-adjusting fiber and the polyester fiber are mixed in the opening and cleaning process, and the remainder is the same as in Example 1.

[0058] Raw material preparation: the pretreatment of the temperature-adjusting fiber is the same as in Example 1; the polyester fiber is prone to static electricity due to its low moisture regain, and is pretreated with a cationic antistatic agent, which is a prior art.

[0059] Mixing method: the temperature-adjusting fiber and the polyester fiber are mixed in the opening and cleaning process, and the remainder is the same a...

Embodiment 3

[0068] The temperature-adjusted cashmere yarn used in the manufacture of cashmere sweaters is designed to be 28tex.

[0069] Raw material selection: temperature regulating fiber fineness is 1.7dtex, length is 40mm; milk protein fiber fineness is 1.7dtex, length is 40mm; cashmere fineness is 14.8um, length is 40mm, blending ratio is 30:10:60.

[0070] Technological process: the mixture of temperature-adjusting fiber and milk protein fiber is opened, cleaned, and carded; cashmere is wooled and carded; the rest is the same as in Example 1.

[0071] Raw material preparation: Antistatic treatment is carried out on the 40% mixture composed of temperature-regulating fiber and milk protein fiber with a special spinning auxiliary for heat storage and temperature regulation, and the addition amount is 6% of the mass of the mixture fiber, and the remainder is the same as in Example 1.

[0072] Mixing method: use strip mixing method. Specifically, the mixed strips of temperature-adjustin...

Abstract

The invention discloses a thermoregulation cashmere yarn and a production method thereof. The thermoregulation cashmere yarn is characterized in that the fineness is 33.3-100tex, the thermoregulation cashmere yarn is formed by blending the following components according to mass ratio: 30-60% of thermoregulation fiber, 30-60% of cashmere fiber and 10-30% of third fiber; the thermoregulation fiber is rayon-based thermal-storage thermoregulation fiber, the fineness is 1.7-2.2dtex, and the length is 38-42nm; for the cashmere fiber, the fineness is 14-16mum, and the length is 36-44mm; and the third fiber is modal fiber, polyster fiber or milk protein fiber, the fineness is 1.7-2.2dtex, and the length is 38-42mm. The production method is suitable for the thermoregulation cashmere yarn, and comprises the following steps: respectively producing the thermoregulation fiber, third fiber mixed strips and cashmere strips, then drawing and doubling the mixed strips and the cashmere strips according to design, then roving, finely spinning and spooling the mixed strips and the cashmere strips in sequence, and finally obtaining the thermoregulation cashmere yarn.

Description

technical field [0001] The invention relates to cashmere blended yarn technology, in particular to a temperature-adjusted cashmere yarn blended with heat-storing and temperature-regulating fibers and cashmere fibers and a manufacturing method thereof. Background technique [0002] Traditional thermal insulation fabrics mainly achieve thermal insulation by means of thermal insulation. The mechanism of heat preservation is to utilize the still air with low thermal conductivity contained in the micropores of the fabric. Insulation effectiveness depends on the number of pores and still air contained in the fabric. Generally speaking, the thicker the fabric, the smaller the density, the more micropores inside it, the more still air trapped inside the fabric, and the better the heat preservation effect. However, the above-mentioned thermal insulation effect is unidirectional and is affected by factors such as external pressure and moisture. [0003] Different from the tradition...
