Embodiment 1

[0036] Take the high-strength flame-retardant polypropylene fiber and flame-retardant polyester fiber raw materials with a weight ratio of 4:1 and put them into the bale unpacking machine for automatic unpacking and mixing. 950 rpm, followed by fine opening and loosening. The fine machine used is equipped with 7 nail chisel plates, and the speed is set at 950 rpm.

[0037] The fiber raw material after opening is quantitatively flowed into the carding machine through the vibrating cotton feeder to be carded into a net shape. The carding machine contains double cylinders and double doffers. The fluffy mesh fiber flows into the cotton laying machine and lays 8 layers back and forth, with a thickness of 30cm~35cm, and then sent to the drafting machine for uniform thinning to 10cm.

[0038] The thinned cotton web is first pre-acupunctured. The frequency of the pre-acupuncture machine is set at 500 punctures / minute, the needle density is 4000 pieces / m, the diameter of the needle hol...

Abstract

The invention discloses a processing technology of needle-punched non-woven fabric. According to the processing technology of the needle-punched non-woven fabric, high-strength inflaming retarding polypropylene fibers and inflaming retarding polyester fibers are used as raw materials. The processing technology comprises the steps of unpacking, material mixing, opening, cotton feeding, carding, lapping, drafting, needle punching, hot rolling and coiling. According to the mode, professional equipment and adjustment are utilized for guaranteeing the uniformity and the thickness of lapping of the fibers, cloth with uniform longitudinal and transverse fiber networks is formed by accurate needle punching of three needle punching machines, and the formed non-woven fabric is soft in hand feel, high in strength, small in ductility, light in weight and resistant to abrasion, acid and alkali; due to the fact that stretching resistance and tearing resistance in the longitudinal direction and the transverse direction are improved greatly, the non-woven fabric is good in water washing and dry cleaning effect; meanwhile, due to the waterproof, fireproof, non-toxic and environment-friendly characteristics, the non-woven fabric is widely applicable to the fields of soft sofas, home decoration, car seats, interior trim and the like.

Description

technical field [0001] The invention relates to the field of non-woven fabric processing, in particular to a processing technology of needle-punched non-woven fabric. Background technique [0002] Non-woven fabric is a kind of fabric formed without spinning and weaving. It just bonds the fibers together directly through physical methods, breaking through the traditional textile principle, and has the advantages of fast production rate, low cost, wide application, Many sources and so on. [0003] Non-woven fabrics are light, soft, breathable, water-repellent, antibacterial, and environmentally friendly, but compared with woven fabrics, they have poorer strength and durability, and cannot be washed like woven fabrics. Contents of the invention [0004] The main technical problem to be solved by the present invention is to provide a processing technology for needle-punched non-woven fabrics, which can guide the production of non-woven fabrics with high strength, tear resista...
