A production method capable of improving the handle of wool-polyester blended yarn

Abstract

The invention relates to a production method capable of improving the hand feeling of wool-polyester blended yarn, comprising the following steps: A, making a polyester primary mixed strip; B, making a polyester secondary mixed strip, C, making a wool-polyester blended strip, D, and then Carry out the second principle by the needle-shaped needle carding machine, E, then carry out the combing process, F, then carry out the sliver by the needle-circle needle carding machine, G, then carry out the first principle by the chain-type needle carding machine, H, then carry out 2 principles by chain type needle carding machine, I, then carry out 3 principles by chain type needle card machine, J, then carry out 4 principles by chain type needle card machine, K, make roving, L, Then use the method of polyfiber spinning to make spun yarn, M, take two spun yarns through the doubling machine in an S-shaped direction and synthesize one yarn; N, twist the combined yarn through a two-for-one twister, O. Finally, the yarn is steamed, which greatly improves the feel of the wool-polyester blended yarn.

Description

【Technical field】 [0001] The invention relates to the technical field of spinning, in particular to a production method capable of improving the handle of wool-polyester blended yarn. 【Background technique】 [0002] Wool and polyester fabrics refer to fabrics made of wool and polyester blended yarns. Wool and polyester fabrics can not only maintain the advantages of wool, but also give full play to the advantages of polyester. Almost all coarse and worsted wool fabrics have corresponding wool-polyester blended varieties. [0003] As we all know, the quality of the fabric comes from the quality of the yarn. The wool-polyester blended yarn in the prior art generally has the following defects: 1. Polyester fibers are all of equal length and have no long or short fibers, so they cannot be exposed on the surface of the fabric after being woven into the fabric. , poor hand feel; 2. The 3mm hairiness index is controlled relatively large during spinning, which is easy to pilling a...
