Embodiment 1

[0021] A method for processing short hemp that is not easy to fade, the specific steps are as follows:

[0022] Step 1, obtaining raw hemp: processing and soaking the stems of the harvested hemp in clean water until the hemp skin is soft, and peeling the skin by hand to obtain raw hemp;

[0023] Step 2, screening: divide the raw hemp into strands and comb the short hemp on the combing machine, and comb the long hemp to keep only the short hemp;

[0024] Step 3, pretreatment: Soak the short hemp successively in water, a surfactant and a urea solution with a mass fraction of 15%. The surfactant includes a mixture of fatty alcohol polyoxyethylene ether sodium sulfate and lecithin, and then the Steam and cook for 35 minutes, and finally squeeze and knead the short hemp repeatedly;

[0025] Step 4, carding: straighten the product of step 3 on the combined carding machine, then use 2 needle combs to straighten the product and make fiber strips;

[0026] Step 5, combing: combing th...

Abstract

The invention discloses a processing method for short hemp which does not easily fade. The method specifically comprises the following steps of 1, acquisition of original hemp; 2, screening, wherein the short hemp is reserved; 3, pretreatment, wherein the short hemp is sequentially soaked in water, a surfactant and a urea solution, then cooked for 25-40 minutes at 60-78 DEG C and finally repeatedly extruded and rubbed; 4, carding; 5, combing, wherein the product in the fourth step is combed, and the product is straightened by four needle combs to prepare fiber strips; 6, yarn boiling, whereinrough yarn is boiled in a yarn boiling box through the addition of auxiliaries and assistance of ultrasonic waves to obtain fine yarn; 7, preparation of a finished product, wherein the fine yarn is dried in an oven at 60-72 DEG C, then reeled into a cylinder on a bobbin winder and then packaged to obtain the finished product. The processing method is simple, and the prepared short hemp can be blended with fibers such as wool and cotton; since the interior structure of short hemp is looser than that of existing short hemp, the color can be adsorbed, and the fading phenomenon cannot occur.

Description

technical field [0001] The invention relates to the field of short hemp processing, in particular to a short hemp processing method which is not easy to fade. Background technique [0002] Textile is a product made of textile fibers through processing and weaving. It is divided into two categories: woven fabric and knitted fabric, including yarn, thread, natural silk, rayon, chemical fiber long and short yarn, elastic yarn, metal wire and other textile raw materials. , knitted fabrics, woven fabrics, non-woven fabrics, natural fur fabrics, plastic fabrics, industrial fabrics, clothing, clothing accessories, home textiles, decorative fabric products, gloves, hats, socks, bags, blankets, etc. and other textiles. China is one of the first countries in the world to produce textiles. [0003] Short linen is a kind of flax, and it is also a commonly used textile raw material. The finished product is easy to fade, which not only affects the decoration of the finished product, bu...
