Problems solved by technology

Fabric softening methods cannot significantly reduce the bending stiffness of fabric surface hairiness, because these treatments can only change the slip resistance between yarns in the fabric, but not the structure and properties of the fibers themselves
As can be seen from the above, there is still no effective way to alleviate or even eliminate the itching of linen fabrics

Embodiment 1

[0029]The ramie yarn is used as the yarn core, and the wrapped yarn is cotton yarn. On the hollow spindle covered spinning machine, the covered yarn is spun by single wrapping process. The ramie yarn density is 36 pounds, and the cotton yarn is 60 pounds. The production process parameters are: spindle speed 12000r / min, wrapping twist 1000 twists / m.

[0030] Due to the use of wrap spinning, the cotton yarn is wrapped around the ramie yarn to form a wrapped structural yarn with cotton as the outer layer and ramie yarn as the core. Due to the binding and isolation of the wrap spinning yarn, the hairiness of the hemp yarn (ramie fiber end) can be significantly reduced. ) the probability of contact with the skin, thus eliminating the itching of the fabric. Due to the high bending stiffness of ramie fiber, a larger wrapping twist is adopted to ensure that the possibility of contacting the ramie fiber end with the skin is minimized.

[0031] The yarn has both the moisture absorption...

Embodiment 2

[0033] The linen yarn is used as the core yarn, and the nylon DTY filament is used as the outer wrapping yarn. On the hollow spindle covering spinning machine, the covering yarn is spun by a single wrapping process. The specification is 70D / 24F, and the production process parameters are: spindle speed 11800r / min, wrapping twist 800 twists / m.

[0034] Due to the use of wrap spinning, nylon multifilament is wrapped around the linen yarn to form a wrapping structure yarn with nylon outer layer and flax yarn as the core. Fiber end) the probability of contact with the skin, thus eliminating the itching of the fabric. Since the flexural stiffness of flax fiber is lower than that of ramie, a moderate wrapping twist can ensure better tactile comfort of the fabric.

[0035] The outer covering nylon yarn has good wear resistance and elasticity, and the core yarn linen yarn endows the yarn with good moisture absorption and release properties, which is suitable for processing shirts and ...

Abstract

The invention discloses an itch-preventing hemp core wrap yarn and a processing method thereof. The wrap yarn comprises core yarn and covering yarn. The core yarn is linen yarn, the covering yarn is staple fiber yarn or filament yarn, and the staple fiber yarn or the filament yarn is wound on the outer side of the linen yarn and wraps the linen yarn. The processing method includes core yarn unwinding, yarn guiding, covering and winding forming. The linen yarn is used as the core yarn, the staple fiber yarn or the filament yarn which can not cause itchy feeling is used as the covering yarn, and by using the covering yarn to wrap and cover the linen yarn, pasting and shielding of linen yarn hairiness are achieved. When fabric made of the covering yarn touches the skin, puncturing of rigid linen fiber on the skin is avoided, and itching feeling is avoided.

Description

technical field [0001] The invention relates to a covered yarn and a processing method thereof, in particular to a linen covered yarn capable of eliminating the itching feeling of the hemp fiber fabric and a processing method thereof, belonging to the technical field of covered spinning. Background technique [0002] Hemp fiber is an important textile raw material, and its main component is cellulose. Due to its special morphological structure, hemp fiber has good moisture absorption and release properties, and is suitable for producing summer clothing fabrics. However, due to the high bending stiffness of hemp fiber (such as the relative bending stiffness of ramie fiber is 9.32×10 4 cN cm 2 , is the largest of all common fibers, even larger than glass fiber 8.54×10 4 cN cm 2 ), the fiber is rigid, and when the fabric made of hemp fiber is worn next to the skin, the hairiness (fiber end) on the surface of the fabric can bear a large bending load, and when it comes into co...
