Abstract
The invention provides a method for preparing a surface layer of a sanitary towel for sports, which is characterized by comprising the following steps: the polylactic acid material is loosened and then mixed with the ES material or the bamboo charcoal material, and then carding, thermal bonding and web forming are sequentially carried out, so that the non-woven fabric material of the surface layer of the sanitary towel for sports is obtained. The invention has simple preparation method, ensures the bacteriostasis, skin friendliness and air permeability of the surface layer of the sports sanitary towel, greatly improves the high temperature resistance of the surface layer non-woven fabric raw material polylactic acid, and ensures that the novel biological textile material has the possibility of adopting the most advanced international heat sealing process technology in the production process of the sanitary towel, thereby overcoming the defects of the traditional spunlace production process, effectively ensuring the integral flexibility and strength of the sanitary towel after being formed, ensuring that the sanitary towel is more comfortable and not itchy, and being more suitable for the requirements of large exercise amount of female athletes.
Description
The technical field is as follows:
the invention relates to the field of manufacturing of sanitary products, in particular to a method for preparing a surface layer of a sanitary towel for sports.
Background art:
women account for a large proportion of athletes involved in gymnastics, cheering exercises, gymnastics, rhythmic exercises, etc., and these women need a large amount of training in daily training. To ensure performance, female athletes do not stop training when they encounter a physiological period. At this moment, the situation of using sanitary towel to train continuously will appear, and traditional sanitary towel top layer adopts water thorn technique air-laid composite non-woven fabrics (promptly water thorn non-woven fabrics) mostly, and the sportsman can produce a large amount of sweat and body heat gathering and the skin of water thorn non-woven fabrics contact will produce the sense of itching when the water thorn non-woven fabrics during the training, causes the discomfort, the completion degree that the action influences the training in the light then, the action that seriously is irregular can increase sportsman's injured probability scheduling problem. In addition, the sanitary towel and the surface layer of the sanitary towel are in a high-temperature high-humidity environment for a long time and are easy to breed bacteria, so that the possibility of athlete suffering from diseases is increased.
Although some sanitary napkins made of polylactic acid materials in the prior art can achieve good air permeability and skin-friendly effects, the polylactic acid materials are biological materials and have poor temperature resistance, so that the surface layer cannot be subjected to high-temperature (above 165 ℃) heat sealing molding with a flow guide layer, a liquid absorption layer and a bottom layer in the sanitary napkin, and only low-temperature (below 140 ℃) hot melt adhesive molding can be performed, so that the sanitary napkin is low in overall strength and only suitable for normal human activities, but for athletes, particularly athletes who perform gymnastics, cheering exercises, rhythm exercises and the like, the exercise amount is large, the activity of the trunk and limbs of the body is large during exercise, the angles are variable, and the situation that the sanitary napkin is cracked integrally often occurs due to rapid exertion.
The invention content is as follows:
the invention aims to overcome the defects in the prior art and provides a method for preparing a surface layer of a sanitary towel for sports.
The invention provides the following technical scheme:
a method for preparing a surface layer of a sanitary towel for sports is characterized in that: the polylactic acid material is loosened, then the loosened polylactic acid material and the ES material or the bamboo charcoal material are put into a cotton mixing box to be stirred and mixed, and then carding, thermal bonding and web forming are sequentially carried out, so that the surface layer non-woven fabric material of the novel sports sanitary towel is obtained.
On the basis of the technical scheme, the following further technical scheme can be provided:
the weight ratio of the polylactic acid material to the ES material is 70 percent, and the ES material or bamboo charcoal material is 30 percent.
The invention has the advantages that:
the invention has simple preparation method, greatly improves the high temperature resistance (capable of withstanding the temperature of 195 ℃) of the non-woven fabric raw material polylactic acid for manufacturing the surface layer of the sanitary towel while ensuring the bacteriostasis, skin friendliness and air permeability of the surface layer of the sports sanitary towel, and ensures that the novel biological textile material can bear the most advanced international heat sealing technology in the production process of the sanitary towel, thereby overcoming the defects of the traditional spunlace production technology, effectively ensuring the integral flexibility and strength of the sanitary towel after being formed, ensuring that the sanitary towel is more comfortable and not itchy, and being more suitable for the requirements of large exercise amount of female athletes.
The specific implementation mode is as follows:
a method for preparing a surface layer of a sanitary towel for sports is characterized in that: the polylactic acid material is loosened and then thrown into a cotton mixing box together with the ES material to be stirred and mixed, wherein the weight ratio of the polylactic acid material to the ES material is 70% and 30% respectively. And then the obtained mixed material is sequentially carded, thermally bonded and formed into a net, thus obtaining the non-woven fabric material of the surface layer of the novel sports sanitary towel.
Claims (2)
1. A method for preparing a surface layer of a sanitary towel for sports is characterized in that: the polylactic acid material is loosened, then the loosened polylactic acid material and the ES material or the bamboo charcoal material are put into a cotton mixing box to be stirred and mixed, and then carding, thermal bonding and web forming are sequentially carried out, so that the surface layer non-woven fabric material of the novel sports sanitary towel is obtained.
2. A method of forming a topsheet for a sports sanitary napkin according to claim 1, wherein: the weight ratio of the polylactic acid material to the ES material is 70 percent, and the ES material or bamboo charcoal material is 30 percent.
