The method is safe, environment-friendly, energy-saving, efficient, high in automation level, and advanced in spunlaced kapok nonwoven fabric weaving, and various characteristics of fiber raw materials are protected effectively.

The invention discloses a sirospun yarn and a spinning method thereof. The yarn consists of 25-35 wt% of coffee carbon fiber, 25-35 wt% of bamboo-carbon fiber and 30-40 wt% of cotton fiber, wherein the fibers are spun into the yarn through a siro spinning process. The spinning method sequentially comprises a loose fiber dyeing process, a cotton carding process, a drawing process, a roving process, a fine yarn siro spinning process and a spooling process. The yarn is formed by blending various fibers, the characteristics of each fiber are highlighted by reasonably setting the weight proportion of each fiber, the advantages of various fibers are integrated, the basic performance of the yarn is kept, the propagation of bacteria is restrained, the release of odor ammonia is reduced, and peculiar smell of alcohol, tobacco and the like can also be effectively removed. Compared with the conventional spinning process, the sirospun yarn disclosed by the invention has less hairness than the ordinary ring spun yarn, particularly the long hairness longer than 3mm is well improved, the method has greater advantages in size dyeing, weaving, singeing and other processes, and the woven fabric has a good wear-resisting property, a good anti-pilling performance and better surface handfeel and softness.

The invention discloses a blended yarn of a jute fiber, a hemp fiber and a silk fiber. The blended yarn is made by blending the following raw materials in percentage by weight: 30 to 55 percent of jute fiber, 20 to 30 percent of hemp fiber and 25 to 40 percent of silk fiber. By blending the jute yarn, the jute fiber, the hemp fiber and the silk fiber in a reasonable proportion, the blended yarn overcomes the defects that the jute fabric is rough and hard and easy to drape, and has the advantages of moisture absorption, air permeability, antibacterium and the like of the jute fabric. Blended fabric made of the blended yarn is elegant, bright and exquisite in dyeing effect, is smooth and warm, has soft handfeel, and has the functions of dispersing sound wave, broadcast, ultraviolet and the like. Besides, the blended yarn is suitable for making warm clothes, ultraviolet radiation prevention clothes and the like.

The invention relates to a modification method of ramie fibers. The modification method comprises the following steps: step 1, proportioning cottonseed shell ash, rice straw ash and sodium hydroxide according to a weight ratio of 10 to (5-8) to (1-2) to obtain a mixture, adding the mixture into water which is 10-15 times the total weight of the mixture, boiling and preparing a modified solution; step 2, adding the ramie fibers into the modified solution to be completely immersed, and cooking for 2-4 hours; and step 3, taking the ramie fibers out of the modified solution, washing the ramie fibers with clear water, and naturally drying the ramie fibers in air. Compared with the prior art, the method disclosed by the invention has the advantages that characteristics such as degree of crystallinity and degree of orientation of the ramie fibers are improved, a prodding and itching feeling generated when the ramie fibers are in contact with a human body is eliminated to certain extent, unique fiber hole cavity structures of the ramie fibers are not damaged, and grooved cavities in the middle of the fibers are not damaged, so that characteristics such as bacteria resistance and bacteriostasis, deodorization and adsorption, moisture absorption and ventilation, mildew prevention and wear resistance of the ramie fibers can be kept.

The invention relates to a bamboo pulp fiber blended spinning decoration fabric manufactured in the textile industry. The warp and weft yarns comprises bamboo pulp fiber, polybutylece terephthalate propylene glycol ester fiber and crude high elasticity acrylic fiber wrinkle resistant short fiber, the warp and weft yarns adopt combed two-fold yarns of 27.8 tex, the twist degree of the yarns is larger than or equal to 700 twists per meter, the fabric texture adopts satin jacquard, and the densities of the warp and weft yarns respectively adopt 800 to 900 yarns per 10 cm and 380 to 420 yarns per 10 cm; the post-treatment technology of the fabric adopts cellulolytic enzyme SD-05 to perform the desizing and polishing treatment, and then the stentering and shaping treatment is performed to the fabric under the condition that the temperature is controlled to be between 130 to 150 DEG C and the time is controlled to be 20 to 30 minutes. The bamboo pulp fiber blended spinning decoration fabric has the advantages that the advantages of the bamboo pulp fiber fabric of bacterial resistance, ultraviolet ray absorbing, air permeability and cooling, etc. are maintained, the disadvantages of the bamboo pulp fiber fabric are remedied, and the bamboo pulp fiber blended spinning decoration fabric also has the advantages of shrink prevention, wrinkle resistance, high intensity and wear resistance, etc.; the process of the biological enzyme treatment technology is soft, and the treatment technology is environment protective.
