One of the important quality indicators of the hemp fiber hemp fiber fineness, fine varieties of hemp fiber fineness in the 1800 public support (0.56tex), medium fineness of 1500 to 1800 public support (0.67 0.56tex), fine public support (0.67tex 1500) for the low-level Ma. With a hemp tip, Wind Flags Advertising the middle of the roots of fineness are inconsistent, the harvest season, the number of Ma fineness is not the same. Hemp fabric to the high-end thin fabric direction, the yarn count, evenness, so that the fabric surface roughness to improve even dyeing. Should first cultivate the fineness of greater than 1800 hectares of excellent grade hemp (0.56tex), if followed by the harvest of raw jute and raw jute first tip of the middle of the root part of the file processing, may also improve the spinning the quality of weaving, which is favorable to improve the quality of dyeing and finishing of the final product. Ramie degumming of whether the request will directly affect the quality of spinning and fabric surface roughness.
Chemical fiber chemical fiber varieties, differential fiber, such as hollow fibers, shaped fibers, air textured yarns network wire, cationic dyeable fiber, anti-pilling fibers, microfiber, as well as high strength and high modulus fibers, fiber; functional fibers such as flame-retardant fiber, antistatic fiber, high hygroscopic fiber, Cheap Wind Flags Wind Flags Advertising aramid, etc.. A variety of fiber blends used in the spinning process, which will inevitably bring about the complexity of the process of dyeing, and therefore must pay attention to the quality of the Advertising Flags For Businesses chemical fiber, but also should take into account the difficulty and feasibility of dyeing and finishing.
Chemical fiber quality indicators generally include the fiber breaking strength, elongation, length deviation, times the long-fiber content, dyeing performance. In addition, the viscose fibers, wet strength and wet elongation and hook strength and residual sulfur content; PVA acetal degrees, water softening points, hue, shaped fiber content; acrylic color yield and dyeing compatibility value; polyester including of boiling water shrinkage, strength unequal, Maker Swooper Flags uneven elongation rate. Others such as fiber curl, moisture regain, as a quality indicator of chemical fiber. These quality indicators are closely related to the textile technology and quality of gauze, and dyeing and finishing of the final product quality. Wind Flags Advertising
The appearance of the defect of the chemical fiber coarse silk, and silk, abnormal filaments, as well as oil, viscose fibers including viscose. Chemical fiber the appearance of the defect affecting its spinnability, Teardrop Flags For Sale but also affect the quality of the finished product. Wind Flags Advertising Different factories or different brands of the same factory, chemical fibers, due to the different production batch, can lead to differences in the manufacturing process, so that shrinkage, dyeing properties are not completely consistent, it is equipped with chemical fiber raw materials in the spinning full attention, otherwise irregular contraction in the dyeing and finishing, the formation of color unevenness and other defects.
(B) the quality of yarn products
Yarn quality will first affect the weaving products, but will ultimately affect the dyeing and finishing of the final product, all the yarn or fabric flaws will be exposed in the dyeing and finishing, Backpack Banner Price so the correct use of textile fibers is very important. Spinning should be the first great importance to fiber ratio of raw materials, the process of spinning cotton with cotton should be noted that the place of origin, grade, batch number; use polyester to the attention of the country, brand, batch number and whether bleaching in the manufacturing process or extinction. Polyester color yield is closely related to these factors. Wind Flags Advertising
(1) the ratio of the fiber raw material and mixing in the dyeing and finishing are often inconsistent due to the ratio of fiber raw materials, mixing bad or textile production mismanagement (such as raw materials mixed with the wrong batch turned wrong, blending ratio, wrong, etc.)
