Embodiment 1

[0043] a linoleum base cloth,

[0044] After crystallization and drying, the polyester chips are input into the screw extruder, and then enter the A and B spinning boxes respectively through the filter and the metering pump. The melt quantitatively passes through the spinneret to form primary fibers. And swing the yarn, lay evenly on the netting curtain to form two layers of fiber webs A and B, and at the same time, the uniform dividing machine adds glass fibers with an interval of 8mm between the two layers of fiber webs A and B, and the fiber nets are sucked firmly by suction. After pre-acupuncture and combination, the glass fiber is straightened by the pre-extrusion cloth, reinforced by main acupuncture, dipped in glue, dried and rolled to obtain the finished linoleum base cloth.

[0045] The pre-acupuncture and the main acupuncture process adopt long-filament acupuncture, and the needle planting density is 4000 pieces / m2, the acupuncture frequency is 1500 times / min, and th...

Embodiment 2

[0049]After crystallization and drying, the polyester chips are input into the screw extruder, and then enter the A and B spinning boxes respectively through the filter and the metering pump. The melt quantitatively passes through the spinneret to form primary fibers. And swing the yarn, lay evenly on the netting curtain to form two layers of fiber webs A and B, and at the same time, the uniform splitter adds glass fibers with an interval of 6mm between the two layers of fiber webs A and B, and the fiber webs are sucked firmly by suction. After pre-acupuncture and combination, the glass fiber is straightened by the pre-extrusion cloth, reinforced by main acupuncture, dipped in glue, dried and rolled to obtain the finished linoleum base cloth.

[0050] The pre-acupuncture and the main acupuncture process adopt long-filament acupuncture, and the needle planting density is 3500 pieces / m2, the acupuncture frequency is 1400 times / min, the acupuncture depth is 6mm, and the starch adh...

Embodiment 3

[0054] After crystallization and drying, the polyester chips are input into the screw extruder, and then enter the A and B spinning boxes respectively through the filter and the metering pump. The melt quantitatively passes through the spinneret to form primary fibers. And swing the yarn, lay evenly on the netting curtain to form two layers of fiber webs A and B, and at the same time, the uniform splitter adds glass fibers with an interval of 10mm between the two layers of fiber webs A and B, and the fiber webs are sucked firmly by suction. After pre-acupuncture and combination, the glass fiber is straightened by the pre-extrusion cloth, reinforced by main acupuncture, dipped in glue, dried and rolled to obtain the finished linoleum base cloth.

[0055] The pre-acupuncture and the main acupuncture process adopt long-filament acupuncture, and the needle planting density is 4500 pieces / m2, the acupuncture frequency is 1600 times / min, and the acupuncture depth is 10mm. The concen...

Abstract

The invention belongs to the technical field of production of spunbonded nonwoven fabrics and provides oil felt base cloth. The oil felt base cloth comprises a fiber web layer I and a fiber web layerII which are sequentially arranged from top to bottom, wherein a plurality of reinforcing ribs are arranged between the fiber web layer I and the fiber web layer II and are uniformly distributed in the transverse direction of fiber webs, and the fiber web layer I, the reinforcing ribs and the fiber web layer II are reinforced through needling and gum dipping. The invention also provides a production method of the oil felt base cloth. The production method comprises the following steps that polyester chips are all processed into the fiber web layer I and the fiber web layer II, fiber glass filaments are added between the fiber web layer I and the fiber web layer II to obtain middle cloth, pre-needling, main needling, gum dipping and drying are conducted on the middle cloth to obtain an oilfelt base cloth finished product. By adopting the above technical scheme, the problem is solved that in the prior art, a nonwoven fabric is high in heat shrinkage rate and is prone to deformation.

Description

technical field [0001] The invention belongs to the technical field of preparation of spun-bonded non-woven fabrics, and relates to a linoleum base cloth and a preparation method thereof. Background technique [0002] Polyester base fabric is one of the important raw materials for waterproof membranes. With the rapid development of China's urbanization, most of the linoleum base fabric products in the domestic market currently range from staple fiber carding needle-punched non-woven fabrics to polyester filament spunbond needles. The transformation of the puncture base fabric, while foreign countries (Europe and the United States) have adopted a large number of low-weight polyester filament reinforced tire base fabrics to increase production speed and improve the dry heat shrinkage and stability of linoleum. [0003] Under the same tensile strength, the non-woven fabrics in the prior art generally have a heat shrinkage rate of more than 1%, which causes the non-woven fabrics...
