However, the bending stiffness of the fiber is relatively large, and all of them are processed by technical fibers, so that if figure 1 The upper rake angle α of the needle teeth shown 1 ' is 15°, the tooth pitch p' of the pin teeth is 1.6 mm, the total height H' of the pin teeth is 2.5 mm, and the conventional licker-in rack with a base thickness W of 0.7 mm is not sufficient for fine jute fiber carding, and the fiber The degree of transfer is not high, it is not suitable for medium-speed production, the product quality is relatively low, and the fibers still have entanglement

Embodiment Construction

[0018] As shown in Figure 2, a special licker-in rack for refined jute fibers includes a base 2 and needle teeth 1 uniformly distributed on the base 2, and is characterized in that the needle teeth 1 adopt double rake angles, left and right double The arc surface and the small teeth are densely arranged, and the upper rake angle α of the needle teeth 1 evenly distributed on the base 2 1 16-18 degrees, pin tooth lower rake angle α 2 20-25 degrees, the tangential angle β of the arc surface on the left 1 40-45 degrees, the tangential angle β of the arc surface on the right 2 is 13-15 degrees, the pitch P of the pin teeth is 5.5-6.0 mm, the thickness a of the pin teeth is 0.06-0.08 mm, the thickness b of the tooth root is 0.3 mm, the height h of the tooth tip is 3.15 mm, and the total height H of the pin teeth is 5.85-6.15 mm, the density of the needle teeth is 30 teeth / square inch, the base thickness W of the base 2 is 0.58-0.62 mm, and the base height C is 1.2 mm;

Abstract

This invention belongs to spin special field. It refers to elaborate jute floss fiber special stab roller fit to medium speed card use. The needle cloth includes base and acicula distributing on the base symmetrically. Its trait is the acicula adopt double forward angle or three forward angles, around double arc side and little close acicula configure. The needle cloth can assure elaborate jute floss fiber ripple plenty, transfer in time, no fiber enlace phenomena that let spinning get excellent level.

Description

Technical field: [0001] The invention belongs to the field of special textile parts, and in particular relates to a special licker-in rack for fine jute fibers suitable for medium-speed carding machines. Background technique: [0002] The refined jute fiber is a kind of cellulose fiber. While adhering to the advantages of ordinary cellulose fiber, the fineness is increased to more than 1800Nm by using a special degumming and refining method, which overcomes the rough and itchy feel of ordinary hemp products. It is possible to make hemp fiber into high-grade close-fitting fabrics due to its shortcomings such as feeling, and it can be better blended with various other fibers, thus greatly expanding its application range. However, the bending stiffness of the fiber is relatively large, and all of them are processed by technical fibers, so that if figure 1 The upper rake angle α of the needle teeth shown 1 ' is 15°, the tooth pitch p' of the pin teeth is 1.6 mm, the total heig...
