Embodiment 1

[0017] Example 1: A preparation method for preparing knitwear with cashmere fiber worsted slubbed composite yarn, which is obtained through the following steps: Step A): Take cashmere with a fineness between 15 μm and 16 μm and a length between 28 mm and 30 mm The fiber is carried out the spinning step of blending → carding → spinning to make a cashmere slub single yarn with a yarn count of 26Nm, a twist of 440T / m, and a twist direction of Z. Step B): Take cashmere fibers with a fineness between 15 μm and 16 μm and a length between 36 mm and 38 mm for blending → combing → carding → combing → whole sliver → mixed sliver → combing → needle combing → roving → The spinning step of the spun yarn is made into a cashmere worsted single yarn with a yarn count of 48Nm, a twist of 760T / m, and a twist direction of Z. Step C): Take three cashmere worsted single yarns and one cashmere slub single yarn to compound and thread to form a composite yarn, and then use a two-for-one twister to ma...

Abstract

The invention discloses a technology for manufacturing worsted and rove composite cashmere fiber yarn. The technology comprises the steps of (A) manufacturing rove, (B) manufacturing worsted, (C) conducting doubling on the rove and the worsted in a composite mode, and (D) obtaining the worsted and rove composite cashmere fiber yarn after heating is conducted through steam. Compared with the prior art, composite doubling at different ratios is conducted on cashmere rove single yarn and cashmere worsted single yarn which are different in thickness, and then the worsted and rove composite cashmere fiber yarn with different hand feels is formed. The manufactured worsted and rove composite cashmere fiber yarn integrates the characteristics that the rove yarn and knitwear made of the rove yarn are soft in hand feel and fluffy and the worsted yarn and knitwear made of the worsted yarn are clear in grain and good in elasticity, and overcomes the defects that according to the rove yarn and the knitwear made of the rove yarn, hairiness is too much, the yarn is loose and fuzzing and pilling are prone to occurrence; in addition, different pieces of manufactured worsted and rove composite cashmere fiber yarn with different mixing ratios have different elasticity degrees and different softness degrees, and therefore different types of cashmere knitwear can be produced.

Description

technical field [0001] The invention relates to a technology of cashmere fiber woolen and worsted composite yarn, which belongs to the field of textile technology. Background technique [0002] Cashmere textiles are popular among consumers. As a scarce textile raw material resource, the technology to improve and increase the added value of its products is developing rapidly. Cashmere spinning technology was originally produced by woolen spinning system, and gradually developed to worsted spinning system in recent years. According to the difference in production process, its products are mainly divided into two categories: woolen cashmere yarn and its knitwear, and worsted cashmere yarn and its knitwear. Slubbed cashmere yarn has a lot of hairiness on the surface and loose yarn. Slubbed cashmere knitwear has the characteristics of soft and fluffy hand feeling; worsted cashmere yarn has smooth surface and tight yarn. Worsted cashmere knitwear has clear lines and elastic nice...
