For example, the polypropylene (pp material) granules are mostly adopted as raw materials and are produced by a continuous one-step method of high-temperature melting, spinning, laying a line and hot-pressing coiling. It is called a cloth because of its appearance and certain properties. Since the earliest realization of industrialization in the united states since 1942, it has become the most rapidly developing new field in textile industry due to its characteristics of simple production process, high yield, low cost, wide product application and the like compared with the traditional woven fabric. The non-woven fabrics can be divided into the following parts according to different processing methods: spun-bonded nonwoven fabrics, spunlaced nonwoven fabrics, heat-sealed nonwoven fabrics, wet-process nonwoven fabrics, needle-punched nonwoven fabrics, and the like. The nonwoven fabric has many excellent functional properties and is extremely widely used, and the nonwoven fabric can be classified into: non-woven fabrics for clothing, furniture decoration/home use non-woven fabrics, non-woven fabrics for medical and health use, non-woven fabrics for filter materials, and the like.
Polyethylene fibers are fibers having the highest specific strength and specific modulus in the world at present, and are fibers/nonwoven fabrics spun from polyethylene having a molecular weight of 100 to 500 ten thousand. The polyethylene fiber/non-woven fabric has low breaking elongation, large breaking work and strong energy absorption capacity, thereby having outstanding impact resistance and cutting resistance, and simultaneously having the advantages of ultraviolet radiation resistance, chemical corrosion resistance, wear resistance and the like.
In the prior art, application publication No. CN110528175A discloses a preparation method of a high-strength high-modulus polyethylene non-woven fabric, which comprises the following steps: (1) preparing materials; (2) and laying; (3) carrying out primary high-pressure spunlace reinforcement; (4) stretching; (5) secondary high-pressure spunlace reinforcement; (6) stretching; (7) carrying out three-time high-pressure spunlace reinforcement; (8) and drying; (9) and (6) rolling. The invention relates to a preparation process of a high-strength high-modulus polyethylene non-woven fabric, which is characterized in that a spunlace non-woven fabric is formed on a polyethylene film which is laid layer by layer through one-time spunlace, two-time spunlace reinforcement, stretching and three-time spunlace, and the spunlace non-woven fabric is manufactured through one-time forming, so that the overall mechanical property of the spunlace non-woven fabric is enhanced, and the spunlace non-woven fabric not only has higher tearing strength, tensile breaking strength and bursting strength, but also has good texture, good water permeability and air permeability, and wide application field.
The above method has the following disadvantages: the high-pressure spunlace is used for reinforcement for many times, so that water resource waste and environmental pollution are caused, and the sustainable development of the environment is not facilitated.
