NOVELTY - Producing graphene cashmere crude spinning comprises e.g. choosing the graphene fiber and cashmere fiber, uniformly mixing the graphene fiber and cashmere fiber, and uniformly spraying oil agent, and stacking, mixing and preserving the mixed fiber, according to the yarn of the fineness requirement, carding and processing the untwisted yarn strip wound into cake shape on the rough spinning carding machine, according to the yarn of the fineness requirement to be produced, twisting the untwisted yarn strip produced by the last process, making the prepared spun yarn into cylinder yarn in the form of loose type spooling, and placing the cylinder yarn in 90℃ hot water to process for 5-10 minutes, then placing in the protease processing liquid with mass fraction of 1.5- 1.8%, soaking for 1.5-2 hours, then inactivating enzyme for 5-10 minutes at 90-95℃ hot water, and then cleaning and drying. USE - The method is useful for producing graphene cashmere crude spinning. ADVANTAGE - The method: uses the compounded cashmere processing oil agent and hair processing, which can make the cashmere in the carding process of parallel stretching degree is good, can improve the embracing of the yarn, lays the foundation for reducing the pilling and pilling, and the spun yarn adopts the protease solution for post-processing, further improve the fluffing and pilling property of the yarn fabric. DETAILED DESCRIPTION - Producing graphene cashmere crude spinning comprises (i) choosing the graphene fiber and cashmere fiber, the fineness of the selected cashmere fiber is 14-25 µm; (ii) uniformly mixing the graphene fiber and cashmere fiber, and uniformly spraying oil agent, and stacking for 20-24 hours, the oil agent comprises lanolin, antistatic agent and silica sol, the and crude oil comprises dodecyl fatty acid ester, fatty alcohol ether, amino super-branched compound quaternary ammonium salt, non-ionic aqueous coconut oil, castor oil polyoxyethylene ether and weak alkaline electrolytic water; (iii) mixing and preserving the mixed fiber, according to the yarn of the fineness requirement, carding and processing the untwisted yarn strip wound into cake shape on the rough spinning carding machine; (iv) according to the yarn of the fineness requirement to be produced, on the roving spinning machine, twisting the untwisted yarn strip produced by the last process according to the production process of the conventional roving spinning machine, the roving spinning device can be ring roving spinning device or vertical spindle roving spinning device, and also can be the roving frame roving spinning device, the twisting twist of the strip according to the change of the yarn count is 38-62 twists/10 cm, the yarn twist is larger, the twist direction can be Z twist or S twist; (v) spooling making the prepared spun yarn into cylinder yarn in the form of loose type spooling; and (vi) placing the cylinder yarn in 90℃ hot water to process for 5-10 minutes, then placing in the protease processing liquid with mass fraction of 1.5- 1.8%, soaking for 1.5-2 hours, then inactivating enzyme for 5-10 minutes at 90-95℃ hot water, and then cleaning and drying.
