The invention provides a high-elastic denim fabric, wherein PTT fiber filaments and spandex filaments are adopted as core yarns. Fasciated yarns are spun into double stretch yarn core-spun yarns, and then the double stretch yarn core-spun yarns are weaved in a three-upward one-downward right twill-weave mode to form cotton roves. After that, the high-elastic denim fabric is prepared successively through the steps of spinning double stretch yarn core-spun yarns, warping, starch dyeing, singeing, desizing, mercerising and washing finished products. The tensile elastic elongation rate of the high-elastic denim fabric prepared by the above method is up to 53.5% and the tensile elastic recovery rate thereof is up to 92.7%. Meanwhile, through setting the ratio of two types of stretch yarns, stretch yarns of different elastic performances can be obtained to meet different elastic requirements. The current situation that the conventional male denim fabric is not elastic can be changed. Meanwhile, the physical and chemical properties and the wearing comfortness of male denim clothes are improved to a certain degree. The fabric is soft and comfortable in hand feeling, good in shape-retaining ability, high in degree of dyeing and good in color fastness, thereby meeting the moderate sport requirement of men when wearing denim clothes. At the same time, the fabric does not unduly fit, thus having a good development prospect and a large value space.

The invention discloses a desizing method for pure cotton fabrics sized by a starch and PVA (Polyvinyl Acetate) mixing pulp and belongs to the pretreatment technology field of pure cotton fabrics. The pure cotton fabrics are subjected to bio-enzyme desizing treatment dip-padding after being pretreated by using hot water and subjected to stacking treatment, active enzyme remaining in the fabrics is removed by an enzyme deactivation treatment, and then the pure cotton fabrics are washed and dried. According to desizing method provided by the invention, the fiber damage is less, the treated fabrics are high in quality and soft in hand feel; particularly, the chromaticity, pH value and COD value of wastewater treated by the desizing method are greatly lower than that of a conventional process, thus the desizing method is in favor of protection of ecological environment, and the load of sewage treatment is greatly reduced. Because dip-padding-stacking continuous treatment processes are used, the desizing method has characteristics of high production efficiency and low labor intensity, and saves energy and water.

The invention relates to an ABO / RhD blood typing detection reagent card and preparation of the ABO / RhD blood typing detection reagent card. The ABO / RhD blood typing detection reagent card is characterized in that the detection reagent card is provided with 8 micro-column gel tubes, wherein one micro-column gel tube contains gel and an anti-A monoclonal antibody of IgM property, one micro-column gel tube contains gel and an anti-B monoclonal antibody of IgM property, one micro-column gel tube contains gel and an anti-D RhD blood type monoclonal antibody of IgM property, and the rest five gel tubes contain gel suspending medium buffer solutions and gels.

The invention relates to a non-woven mask base cloth and a manufacturing method thereof, and belongs to the field of beautifying and skin care. The method comprises the steps that cellulose fiber is unpacked, coarse opening, mixing, fine opening, cotton feeding, carding, cross lapping and drafting are performed and then a lower layer fiber web is formed; water-soluble polyvinyl alcohol fiber is unpacked, secondary opening, airflow cotton feeding and disordered carding are performed and then the fiber is laid on the lower layer fiber web so as to form an upper layer fiber web; the upper layer fiber web and the lower layer fiber web are fed into a high-pressure jetting area together for spunlace reinforcing, so that fiber in the upper layer fiber web and fiber in the lower layer fiber web are entwisted to form a composite fiber web; the composite fiber web is fed into a water soluble area and dissolved to remove polyvinyl alcohol fiber to obtain the single-layer fiber web; the single-layer fiber web is dried, wound and slit to obtain the non-woven mask base cloth. The obtained non-woven mask base cloth has multiple fiber gaps and capillary pores, the problem that a non-woven base cloth for a mask is large in gram weight and poor in skin attachment is solved, and the effects that the non-woven base cloth for the mask is light and thin, can absorb water and is breathable and good in moisturizing and attachment are achieved.

The invention discloses a method for producing saccharide by using biomass. The method comprises the following steps of: reacting raw material size consisting of a biomass raw material, inorganic metal salt, and surfactant at the temperature of between 120 and 180 DEG C for 5 to 30 minutes, and performing enzyme hydrolysis on a solid-liquid mixture which is not separated after reaction to obtain hydrolyzate containing saccharide. The method is short in an operation process, low in energy consumption, and high in biomass utilization rate and a saccharification effect is good.

The invention discloses a method for improving the unwinding ratio of silk, and belongs to the technical field of silk processing. The method comprises the following steps: preparing a silk unwinding agent, penetrating, boiling cocoons, rinsing, regulating silks, spinning, and reeling. The method is scientific and feasible, the operation is feasible, the sericin in the inner layer of cocoons is fully swelled, the temperatures of cocoon boiling and silk regulation are reduced, the inner layer can be cooked, while the dissolution of sericin in the outer layer is inhibited; the cocoon boiling is optimized according to the physical and chemical properties of silk, after the cocoons are processed by the provided method, the silk unwinding ratio can reach 79.6 to 81.2%; the unwinding ratio is improved by 6.2 to 8%; the broken rate of silk during reeling process is reduced by 5.3 to 7.6%, the silk cleanness score reaches 95 to 95.8, and the cleanness score is improved by 2.12 to 2.85.

The invention relates to dendrobium officinale powder preparation method which is characterized by including the steps: (1) material pretreatment; (2) cutting and stirring; (3) freeze-drying; (4) enzymatic hydrolysis; (5) high-pressure homogenizing; (6) fermentation; (7) vacuum concentration; (8) spray-drying. Compared with the prior art, the method has the advantages that the enzymatic hydrolysisis matched with fermentation to generate biochemical doubling effect, preliminary enzymolysis of dendrobium officinale fibers can be achieved by enzymatic hydrolysis treatment, cellulose and hemicellulose in the dendrobium officinale can be converted into fermentable glycogen, nutrients are provided for metabolic acid production of follow-up lactobacillus and acetic bacteria, cellulose is hydrolyzed under acid condition, fibers are further hydrolyzed by enzymes generated after bacillus metabolizes, a firm ester bond formed between lignin and cellulose is destroyed, the prepared dendrobium officinale powder is high in dendrobium officinale fiber content and good in dispersibility, and the utilization rate of dendrobium officinale raw materials is high.
