Pure hemp knitted underwear material without scratchiness and processing method thereof

Abstract

The invention discloses a pure hemp knitted underwear material without scratchiness and a processing method thereof. The reverse side of the fabric knitted by pure hemp yarn is blotch printed to form the front of knitted underwear; the processing method includes the steps of: processing the pure hemp yarn by steam; knitting the wet pure hemp yarn under the conditions of relative humidity more than 85%; singeing the surface of the fabric; performing mercerization treatment on the fabric by using a Baume degree of 13-16 degrees, wherein the treatment temperature is controlled to be 15-20 DEG C; performing biological enzyme treatment on the fabric by using the neutral cellulose enzyme under the conditions of PH value of 6-7 and working temperature of 50-60 DEG C, wherein the treatment time is 60-90 min, and after the treatment is ended, warming to 80 DEG C for inactivation; performing blotch printing on the reverse side of the knitted fabric; finishing the knitted fabric and softening the knitted fabric by using a softening agent; the pure hemp knitted underwear material provided by the invention resists scratchiness, keeps excellent performance and strength of the hemp fiber, and also keeps the elegant appearance of the material.

Description

technical field [0001] The invention relates to a knitted fabric and a processing method thereof, in particular to a processing method of a pure hemp knitted underwear fabric without itch. Background technique [0002] In the prior art, linen knitted fabrics are usually weft knitted fabrics blended with linen and other fibers. Pure linen knitted fabrics are difficult to weave, and more importantly, it is difficult to make underwear fabrics due to the obvious itching of pure linen knitted fabrics. [0003] The reason for the itching feeling of hemp knitted fabrics is that the hemp fiber has high stiffness and uneven thickness. After spinning and weaving, when one end of the thick and hard fiber is not spun into the center of the yarn, it drills out of the surface of the yarn, and because the yarn On the surface of the fabric and the fiber end is exposed on the surface of the fabric, it will cause itching when it comes into contact with the skin. After the yarn loops on the k...

Problems solved by technology

Positive methods include: use yarn singeing and gray cloth singeing to remove hairiness, this method works well for a while, but new hairiness will come out after washing and washing; use soft finishing of fabrics, and the fibers are moistened by chemical agents Decreased rigidity reduces the hardness acting on the skin, thereby reducing the itching sensation, but with the increase of washing times, the softener is washed away, and the itching sensation recovers; the hemp fiber is chemically denatured, and in the existing In this treatment, while the tingling sensation is eliminated, the potent and numbing properties are greatly reduced
