Problems solved by technology

[0004] The manufacturing process of oil-absorbing cotton is to first obtain melt-blown polypropylene non-woven fabrics. The traditional process of polypropylene melt-blown fibers and non-woven fabrics is: propylene particle feeding---melt extrusion---fiber formation--- Fiber cooling---forming into a net on a spinning board---reinforced into a cloth. The oil-absorbing cotton prepared by the above process has defects such as low strength, easy delamination, easy breakage, and difficult to salvage in water.

Embodiment 1

[0021] The invention discloses a preparation method of reinforced oil-absorbing cotton, which comprises the following steps: raw material preparation, melt extrusion, spinning into a net, strengthening into cloth, and eagerly cutting and winding, and also includes sewing up the eagerly cut oil-absorbing cotton 1 , the size of the eagerly cut oil-absorbing cotton 1 is 40cmx50cm, and the stitching process is wired stitching using a mechanical quilting process, and the stitching thread 3 used is a glass fiber yarn, and the diameter of the yarn is 0.8mm. First suture around the oil-absorbing cotton 1, and then suture the surface of the oil-absorbing cotton 1 horizontally and vertically, and the sewing track of the suture line 3 is linear, as shown in figure 1 As shown, the sutures 3 make the surface of the oil-absorbing cotton 1 form several evenly distributed oil-absorbing units 2, the shape of the oil-absorbing units 2 is rectangular, the size is 10cmx10cm, and the sutures 3 dist...

Embodiment 2

[0024] The invention discloses a preparation method of reinforced oil-absorbing cotton, which comprises the following steps: raw material preparation, melt extrusion, spinning into a net, strengthening into cloth, and eagerly cutting and winding, and also includes sewing up the eagerly cut oil-absorbing cotton 1 , the size of the eagerly cut oil-absorbing cotton 1 is 50cmx50cm, and the stitching process is wired stitching that adopts manual sewing, and the stitching thread 3 used is carbon fiber yarn, and the diameter of the yarn is 1.8mm. 1, and then transversely suture the surface of the oil-absorbing cotton 1, the suture track of the suture line 3 is straight, as figure 1 As shown, the sutures 3 make the surface of the oil-absorbing cotton 1 form several evenly distributed oil-absorbing units 2, the shape of the oil-absorbing units 2 is rectangular, the size is 10cmx50cm, and the number of sutures 3 distributed horizontally is 6. The length is 50cm, the vertically distribut...

Abstract

The invention discloses a preparation method of strengthened type oil absorption cotton. The method comprises the following steps of raw material preparation, melting extrusion, spinning and net forming, strengthening and cloth forming and hot cutting and winding, and the method further comprises the step of conducting stitching processing on hot-cut oil absorption cotton; by means of stitching processing, multiple evenly distributed oil absorption units are formed on the surface of the oil absorption cotton, and the stitching area subjected to stitching processing accounts for 1.5%-3.5% of the total area of the oil absorption cotton. By means of the preparation method of the strengthened type oil absorption cotton, the strength of traditional oil absorption cotton is improved, and when the oil absorption cotton is used in water, laying and breaking do not occur, and the oil absorption cotton is easy to refloat.

Description

technical field [0001] The invention relates to the field of preparation of oil-absorbing cotton, in particular to a preparation method of reinforced oil-absorbing cotton. Background technique [0002] Oil-absorbing cotton is also called absorbent cotton, industrial absorbent cotton, and sometimes people simply call it oil-absorbing cotton. According to the characteristics of absorbent materials, it is divided into: oil-absorbing cotton, chemical absorbent cotton (also known as chemical absorbent cotton, liquid absorbent cotton) and general-purpose absorbent cotton. Oil-absorbing cotton can control and absorb petroleum hydrocarbons, various acidic (including hydrofluoric acid), alkaline hazardous chemicals, non-corrosive liquids and large-scale oil spills at sea, etc. Absorbent cotton is the most commonly used item to deal with spills after oil and chemical spills [0003] Oil-absorbing cotton is a kind of fiber and non-woven fabric made of inert polypropylene meltblown af...
