Embodiment 1

[0036] The method for preparing the temperature-regulating fiber is to mix the polyurea-melamine resin wall material hexadecane phase-change microcapsules with the viscose solution, and then press into the coagulation bath for spinning and forming, and then stretch and shape under wet heat. After scouring and drying, the temperature-regulating fiber is obtained. The mass ratio of the polyurea-melamine resin wall material hexadecane microcapsules to the viscose solution is 1:100.

[0037] The preparation method of the polyurea-melamine resin wall material hexadecane microcapsules is: using toluene-2,-4-diisocyanate and 1,6-hexamethylenediamine to synthesize hexadecane microcapsules by interfacial polymerization The inner wall material, and then use melamine resin prepolymer to synthesize the outer wall material of hexadecane microcapsules through in-situ polymerization. The specific preparation process is as follows:

[0038] In the first step, 1 mass part of n-hexadecane and ...

Embodiment 2

[0043] The method for preparing the temperature-regulating fiber is to mix the polyurea-melamine resin wall material hexadecane phase-change microcapsules with the viscose solution, and then press into the coagulation bath for spinning and forming, and then stretch and shape under wet heat. After scouring and drying, the temperature-regulating fiber is obtained. The mass ratio of the polyurea-melamine resin wall material hexadecane microcapsules to the viscose solution is 10:100. The polyurea-melamine resin wall material hexadecane microcapsules and the viscose solution are also added with a mass percentage of 5% hydroxyl Aqueous solution of methylcellulose.

[0044] The preparation method of the polyurea-melamine resin wall material hexadecane microcapsules is: using toluene-2,-4-diisocyanate and 1,6-hexamethylenediamine to synthesize hexadecane microcapsules by interfacial polymerization The inner wall material, and then use melamine resin prepolymer to synthesize the oute...

Embodiment 3

[0049] The method for preparing the temperature-regulating fiber is to mix the polyurea-melamine resin wall material hexadecane phase-change microcapsules with the viscose solution, and then press into the coagulation bath for spinning and forming, and then stretch and shape under wet heat. After scouring and drying, the temperature-regulating fiber is obtained. The mass ratio of the polyurea-melamine resin wall material hexadecane microcapsules to the viscose solution is 1-10:100. The polyurea-melamine resin wall material hexadecane microcapsules and the viscose solution are also added with a mass percentage of 5% hydroxyl Aqueous solution of methylcellulose.

[0050] The preparation method of the polyurea-melamine resin wall material hexadecane microcapsules is: using toluene-2,-4-diisocyanate and 1,6-hexamethylenediamine to synthesize hexadecane microcapsules by interfacial polymerization The inner wall material, and then use melamine resin prepolymer to synthesize the ou...

Abstract

The invention discloses a temperature adjusting fiber and a preparation method thereof. The raw materials of the temperature adjusting fiber contain hexadecane phase change microcapsules of a polyurea-melamine resin wall material, the phase change temperature of the hexadecane phase change microcapsules of the polyurea-melamine resin wall material is 10 to 40 DEG C, and the phase change enthalpy is 100 to 180J / g. The method for preparing the temperature adjusting fiber comprises the following steps of: mixing the hexadecane phase change microcapsules of the polyurea-melamine resin wall material and viscose solution, pressing the mixture into a coagulation bath by jetting, performing spinning molding, performing damp and hot drawing and setting, refining treatment and drying, and obtaining the temperature adjusting fiber.

Description

[0001] technical field [0002] The invention belongs to the field of textiles, and in particular relates to a functional fiber. [0003] Background technique [0004] The air-conditioning fiber is Outlast fiber, and its technology was developed by NASA for the moon landing program. The purpose is to make moon landing clothing for astronauts, including gloves, socks, underwear, etc., and later developed to be used for ordinary clothing, especially outdoor clothing, including ski jackets, pants, sweaters, etc. Outlast air-conditioning fiber is a new type of "smart" fiber, successfully developed in 1988, first used commercially in 1994, used in outdoor clothing in 1997, and is now widely used in fashion and bedding. [0005] Outlast fiber temperature regulation principle: The key to Outlast fiber technology is the use of heat-sensitive phase-change materials wrapped in microcapsules. This material has the function of absorbing, storing and releasing heat in the form of laten...
