摘要： A degradable polyester fiber and its preparation method are disclosed. The preparation method is to cool a PET melt dispersing with doped ZrO2 powder by ring-blowing after extruded from a trilobal spinneret hole on a spinneret, and manufacture a fully drawn yarn (FDY) according to an FDY process with the PET melt, then the degradable polyester fiber is prepared after a relaxation heat treatment. The trilobal spinneret hole on the spinneret has three leaves with unequal lengths and angles, and all the trilobal spinneret holes are distributed in concentric circles, with a center line of the leaf opposite to the smallest angle in each trilobal spinneret hole passing through the center of the circle, and pointing away from the center of the circle. The process is simple, and the obtain fiber has good performances in degradation and elasticity.

摘要： A method for producing a nonwoven fabric made of crimped synthetic fibers, wherein the synthetic fibers are spun and are deposited on a conveyor as a nonwoven web. The deposited nonwoven web is pre-bonded by means of at least one first hot-air bonding device, wherein a main suction air is sucked from below through the conveyor in the area of fiber deposition. A first suction air is sucked from below through the conveyor in the region of the first hot-air bonding device. The air speed of the main suction air is greater than the air speed of the first suction air.

摘要： Techniques are directed to melt spinning, drawing, crimping and winding multiple threads. The threads are spun from a plurality of spinnerets of a spinning device and are drawn as a thread group by a drawing device and are subsequently fed for crimping next to one another to a plurality of texturing units. In order to obtain identical treatment of all threads within the thread group, the threads are guided individually with a plurality of wraps next to one another on a godet unit and, after running off from the godet unit, are guided in a straight thread run parallel next to one another into the texturing units. To this end, adjacent texturing units of the crimping device form a treatment spacing between themselves which is such that, in the case of being guided individually with a plurality of wraps on the godet unit, the threads can be guided in parallel in a straight thread run.

摘要： A continuous fastener element including: a coupling head; upper and lower leg portions; and a connecting portion wherein surfaces of the coupling head, the leg portions, and the connecting portion are each formed as a rough surface with a plurality of recesses. Furthermore, a head surface of the coupling head of the continuous fastener element is formed to have an average roughness Ra smaller than that of outer peripheral surfaces of the leg portions. Accordingly, gloss and luster of the continuous fastener element may be easily reduced or removed. Furthermore, when the slide fastener is formed, the resistance between the coupling heads of the left and right continuous fastener elements may be made small and the left and right element rows may smoothly engage with each other or disengage from each other.
