Problems solved by technology

[0009] As can be seen from the aforementioned data, the elasticity in the elastic waistline of the existing disposable women's menstrual pants is all realized by the elasticity of the elastic threads, and the use of multiple elastic threads may cause relatively serious damage to the abdomen of women in the menstrual period. High pressure, which aggravates the abdominal discomfort of women during menstruation, and affects the user experience of menstrual women

Embodiment 1

[0039] Step 101, mixing PTT fibers with PTT / PET bicomponent fibers to obtain PTT and PTT / PET mixed fibers, the ratio of PTT fibers and PTT / PET bicomponent fibers in the PTT and PTT / PET mixed fibers is 50- 70%: 30-50%, spray antistatic liquid to the PTT and PTT / PET mixed fiber, and leave the sprayed PTT and PTT / PET mixed fiber for 4-6h, make the PTT and PTT / PET The moisture regain of PET mixed fiber reaches 8.1-10.2%, wherein, the proportioning of each component in the described antistatic liquid is antistatic softener: water is 6-10%:90-94%, and described antistatic softener is Non-ionic.

[0040] In step 102, the PTT and PTT / PET mixed fibers after standing are subjected to rough opening, fine opening, carding and cross-lapping processes to obtain PTT and PTT / PET mixed fiber webs, wherein the opening and carding The technological parameters of the process are: the line speed of the opening roller is 550-730m / min, 750-850m / min, 900-950m / min; the speed of the main cylinder is 7...

Embodiment 2

[0059] 201, prepare elastic non-woven fabric:

[0060] A. Selection of raw materials:

[0061] PTT fiber is selected, the fiber fineness is 1.5D, and the length is 38mm; the fiber structure is eccentric PTT / PET bicomponent fiber, the eccentric ratio is 7:3, the fiber fineness is 2D, and the length is 40mm.

[0062] B. Preprocessing:

[0063] PTT fibers are mixed with PTT / PET bicomponent fibers to obtain PTT and PTT / PET mixed fibers, and the ratio of PTT fibers to PTT / PET bicomponent fibers in the PTT and PTT / PET mixed fibers is 70%: 30% , spray antistatic liquid to the PTT and PTT / PET mixed fiber, and leave the sprayed PTT and PTT / PET mixed fiber for 4 hours, so that the moisture regain of the PTT and PTT / PET mixed fiber reaches 8.1% , wherein, the proportioning of each component in the antistatic liquid is antistatic softener: water is 6%: 94%, and the antistatic softener is nonionic.

[0064] C. Preparation of non-woven base fabric:

[0065] (1) Rough opening, fine op...

Embodiment 3

[0079] 301, prepare elastic non-woven fabric:

[0080] A. Selection of raw materials:

[0081] PTT fiber is selected, the fiber fineness is 2D, and the length is 38mm; the fiber structure is eccentric PTT / PET bicomponent fiber, the eccentric ratio is 7:3, the fiber fineness is 2D, and the length is 40mm.

[0082] B. Preprocessing:

[0083] PTT fibers are mixed with PTT / PET bicomponent fibers to obtain PTT and PTT / PET mixed fibers, and the ratio of PTT fibers to PTT / PET bicomponent fibers in the PTT and PTT / PET mixed fibers is 60%: 40% , spray antistatic liquid to the PTT and PTT / PET mixed fiber, and leave the sprayed PTT and PTT / PET mixed fiber for 5 hours, so that the moisture regain of the PTT and PTT / PET mixed fiber reaches 9.2% , wherein, the proportioning of each component in the antistatic liquid is antistatic softener: water is 8%:92%, and the antistatic softener is nonionic.

Abstract

The invention discloses menstrual period trousers and a preparation method thereof, and relates to the technical field of disposable sanitary products. Through selection of PTT fibers and PTT / PET bi-component fibers, the adjustment of opening carding and spunlace reinforcement processes, and selection of special shrinking and a sherring process, the prepared elastic nonwoven fabric has excellent elasticity and good softness, comfort and ventilation of spunlace nonwoven fabric as well as better safety; and when the elastic nonwoven fabric is applied to the waist circumference of the menstrual period trousers, the compression area of the menstrual period trousers on an abdomen of women can be increased, the stress on the abdomen can be more uniform, and the excessive compression of ordinarymenstrual period trousers on the abdomen of women during menstruation can be avoided. At the same time, the processing process of the menstrual period trousers is simple, the processing cost is low, and the menstrual period trousers is suitable for sustainable production.

Description

technical field [0001] The invention relates to the technical field of disposable sanitary products, in particular to menstrual pants and a preparation method thereof. Background technique [0002] Generally, during the life course of a woman from birth to aging, her menstrual cycle is between the ages of 12 and 51, which means that she will be in menstruation for more than 2,300 days in her life. Sanitary napkins have become essential menstrual care products for women. Sanitary napkins can be divided into daily use and night use according to the time of use. However, regardless of daily use or night use, sanitary napkins must be pasted on the underwear for use. In this way, when sleeping in the wrong position or doing sports at night, There will be displacement of sanitary napkins and side leakage. Therefore, when the menstrual flow is relatively large, wearing panty sanitary napkins can make women spend the special days safer and more comfortably. [0003] Women's menstr...
