Embodiment 1

[0031] The cotton-linen blended yarn described in the present embodiment 1 imitates pure linen yarn, and is made up of following raw material:

[0032] Fine cotton card noil 50%

[0033] Fine Staple Cotton 45%

[0034] Linen Loose Fiber 5%.

[0035] The spinning method of imitating pure linen yarn of the cotton-linen blended yarn described in the present embodiment 1 is prepared by the following steps:

[0036] (1) 50% of fine-staple cotton carding noil, 45% of fine-staple cotton and 5% flax loose fibers are opened by a comb-hand opening method to obtain opened fluffy short fibers.

[0037] (2) the fluffy short fiber prepared in the step (1) is made into a roving with a quantitative value of 6.0g / 10m and a twist coefficient of 125 through the carding process→drawing process→roving process; the cover plate in the carding machine The five-point gauge to the cylinder is 14-12-12-12-12; the cylinder speed is 360r / min, and the licker-in roller speed is 810r / min. The drawing pro...

Abstract

The invention belongs to the technical field of textiles, and particularly relates to a cotton and hemp blended yarn based imitation pure hemp yarn and a spinning method thereof. The cotton and hemp blended yarn based imitation pure hemp yarn comprises the following raw materials: 40-70% of fine staple cotton carding noil, 30-50% of fine staple cotton and 0-10% of flax loose fibers. According to the cotton and hemp blended yarn based imitation pure hemp yarn and the spinning method thereof, used spun roving contains a large amount of short fibers; in a drafting process of a spinning frame, dueto the fact that the number of floating fibers is increased, irregular and bamboo-joint-like slubs are formed on the surface of the yarn, are just like hemp joints of a hemp yarn and are similar to hemp in appearance and characteristic; and when the twist factor of a cotton yarn is increased, the cotton yarn is reduced in diameter and becomes hard, a gap between the fibers is reduced, the capillary effect is improved, and the characteristics of water absorption and quick drying can appear.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a cotton-linen blended yarn imitating pure linen yarn and a spinning method thereof. Background technique [0002] Traditional hemp blended yarns are generally spun with hemp fibers such as ramie, flax, jute, etc., which have certain antibacterial and moisture absorption and perspiration functions. Hemp fabrics have good toughness, strength and abrasion resistance higher than cotton cloth, and good hygroscopicity. Excellent water resistance, fast heat conduction, and cool feeling when worn. [0003] Because hemp fiber is obtained from the phloem of hemp by chemical methods such as degumming, pectin, lignin, and hemicellulose remain in the fiber, resulting in high rigidity of the fiber, and the fabric has a tingling feeling and is easy to wrinkle. At the same time, the price of hemp is relatively high. In order to control costs, cotton and linen blended yarns are oft...
