Embodiment example 1
[0029] Cotton-type viscose staple fiber (commonly known as artificial cotton), the relative density of the fiber is 1.50~1.52, the degree of fiber polymerization is about 250~300, and the degree of crystallinity is about 30%; it has a good moisture absorption rate of 11%~13%. The cutting length is 35~40mm. Use wood pulp (α-cellulose content ≥ 89%) or cotton pulp (α-cellulose content ≥ 96%), and NaOH (concentration is about 240g / L) solution to make alkali cellulose, and CS 2 The solution is made into cellulose sulfonate, which is dissolved in dilute lye with a concentration of 6.4-6.6g / L to obtain a spinning stock solution; the spinning stock solution filtered through three times is blended with fat-burning compound essential oil microcapsules, Spinning after vacuum (0.094Mpa) defoaming, obtain as-spun silk, cut off and fall in the water flow after clustering, drafting, heat treatment (H 2 SO 4 ), and then post-processing, and finally the finished product is made after testin...
Embodiment example 2
[0031] High humidity and high modulus viscose fiber (rich fiber, polynosic, modal), the fiber polymerization degree is about 350~500, the fiber crystallinity is about 40%~48%; it has good absorption, and the official moisture regain is 9%- 11%. Use cotton pulp (α-cellulose content ≥ 96%), and NaOH solution to make alkali cellulose, and CS 2 Solution (content not less than 45% of α-cellulose content) is made into cellulose sulfonate, dissolved in dilute alkali (NaOH content should be lower than 62% of α-cellulose content). The spinning stock solution is mixed with the fat-burning compound essential oil microcapsules, and the primary silk is obtained through spinning, which is bundled, drawn, heat-treated, cut off and dropped into the water flow (H 2 SO 4 <40g / L), then post-processing, and finally tested and packaged to make the finished product. The finished regenerated cellulose fat-burning fiber obtained by chemical solvent dissolution method is used to detect and obtain t...
Embodiment example 3
[0033] Solvent-based regenerated cellulose fiber (Lyocell, tencel), fiber polymerization degree is about 500~550, crystallinity is about 50%; moisture absorption rate is 10%~12%. Use high-quality cellulose raw material - pulp (α-cellulose content > 95%, polymerization degree > 600), after shredding, it is directly dissolved in an organic solvent containing an appropriate amount of water N-methylmorpholine-N-oxidation The spinning stock solution prepared in NMMO is filtered and defoamed, and then fully mixed with the fat-burning compound essential oil microcapsules, and then sent to the spinning machine, and then finely Extrude from the hole, go through an air gap layer, enter the coagulation bath to form silk, and then go through washing, oiling, drying, cutting and other processing procedures to obtain the finished product. The finished product regenerated cellulose fat-burning fiber obtained through the chemical solvent dissolution method detects the mass parts array of each...
