Description

544304 A7 B7 V. Description of the invention (Ϊ) ~ ----- Scope of the invention The present invention summarizes the menstrual tampons, and more specifically, the invention relates to recovery. The yarn acts as a tamponed menstrual tampon, and the present invention also relates to a composite yarn intermittently joined with a pile fabric and a method for manufacturing the composite yarn. BACKGROUND OF THE INVENTION Many different absorbent menstrual tampons have long been known for this technique. Most of the menstrual tampons currently on the market include a menstrual tampon material and a connection to one of the menstrual tampon materials to extract the menstruation. The tampon blank is compressed into a generally cylindrical shape to make these menstrual tampons. This technique has been described for menstrual cotton tampons with a variety of different types and configurations, which may be rolled up, spiraled, folded or assembled into a rectangular absorbent pad. Menstrual tampons made of roughly rectangular absorbent material stock have become popular and successful on the market. Absorptive menstrual tampons used today typically consist of a generally cylindrical absorptive menstruation that is compressed to about two-eighths to one-half of an inch (about 1.0 cm to 1.3 cm) in diameter and about 2 cm to 7 cm in length. Cotton tampons, these absorb the ten menstrual cotton tampons, which are usually formed from a cotton fetus having a larger size than the vaginal orifice, and then compress it to the above dimensions (to correspondingly increase rigidity) to facilitate insertion. When absorbing fluid, these compressed menstrual tampons are expected to expand again to their original pre-compressed size and eventually become large enough to effectively cover the vaginal cavity to prevent fluid leakage. Most conventional menstrual tampons have a pull out of the user's body after insertion to facilitate retrieval and disposal of the used tampons. Normal and ten, 544304 A7
