摘要： The invention provides a device that can be used to produce meltblown nanofibers. The meltblown fiber spinning device comprises: a spin block having an inlet side; an outlet side opposite the inlet side; a discharge surface disposed at the outlet side of the spin block; a flow channel formed at the inlet side of the spin block for receiving molten polymer from a polymer source; an inlet surface formed in the flow channel towards the outlet side of the spin block; and a plurality of spaced apart capillaries formed in the inlet surface of the spin block, the capillaries having an inlet end in fluid communication with the flow channel and a discharge end at the discharge surface of the spin block, wherein the capillaries have a diameter (D) in the range of from 2-10 mils and a length (L), wherein the L/D ratio is at least 1 and less than 20, and wherein the number of capillaries is in the range of from 20-200 capillaries per inch. Molten polymer introduced into the flow channel flows into the capillaries and is then extruded from the discharge ends of the capillaries as strands of fine filaments.

摘要： Disclosed is a process for continuous perforation of fabrics that comprise thermoplastic fibers. The process utilizes a combination of heat and pressure to perforate fabrics where the shape, size, and distribution of the individual fabric perforations is define solely by the design of the pattern embossing roll, In particular, the top side of the individual embossing points are not flat but rather have a raised peripheral edge so that the actual fabric contact area of the bond points is much less than total area circumscribed by each bond point. The small ratio of fabric contact area to total bond area concentrates the thermal and compressive forces in the embossing nip and allows a large perforation to be cut out of a fabric moving at high speed through the perforation nip.
摘要翻译：公开了一种用于连续穿孔包含热塑性纤维的织物的方法。该方法利用热量和压力的组合来穿孔织物，其中单个织物穿孔的形状，尺寸和分布仅由图案压花辊的设计来限定。特别地，单个压花点的顶侧不是扁平的，而是具有凸起的外围边缘，使得结合点的实际织物接触面积远小于每个结合点所限定的总面积。织物接触面积与总粘合面积的小比率集中了压花辊隙中的热压力和压缩力，并且允许从织物高速移动通过穿孔辊隙的织物上切出大的穿孔。
