The utility model discloses have natural antibacterial, the air permeability is high, lead efficiency such as wet quick-drying, close skin, and have better top power of breaking, the gas permeability is high, staphylococcus aureus, escherichia coli and candida albicans antibacterial rate all exceed AAA level standard, and polylactic acid fiber part can decompose completely, play certain effect to environmental protection, the thickness reasonable in design of waistband part can make the user can not have the sensation of tightening when wearing, the travelling comfort is high, but wide application in textile technology field.
Description
Technical Field
The utility model relates to the technical field of textile, in particular to polylactic acid fiber elastic underpants.
Background
At present, all domestic cut-piece sewing type underpants are characterized in that the waist head part of the underpants is made of elastic bands or woven belts made of common nylon yarns or polyester yarns and elastic rubber bands, the underpants are woven and then dyed or dyed first and then woven, the warp yarn raw material adopts a mode of bundling 1 warp yarn, and the underpants are directly subjected to high-temperature dry heat setting after the woven belts are finished. The waistband made of chinlon or terylene has poor air permeability and moisture permeability, can bring stuffy feeling to a wearer, and particularly has an allergy problem to the product when the wearer sweats easily in hot weather, so that the wearer can generate red rash on the waist after the wearer sweats. In addition, the common woven belt is made of thicker raw materials, so that the thickness of the woven belt is increased, the hand feeling is stiffer, and the wearing comfort is poor.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a technical scheme does:
the polylactic acid fiber elastic underpants comprise an underpants body, a crotch part, waists and waistband woven belts, wherein the underpants body and the crotch part are of plain structures woven by polylactic acid fibers, polyolefin elastic fibers or high-end low-temperature spandex, and are woven by a high-density circular knitting machine and produced by a complete dyeing and finishing technology; the waistband head woven belt is located on the waistband head and is of a ribbon structure formed by densely weaving polylactic acid fibers and high-end spandex filaments.
Preferably, the polylactic acid fiber content of the waistband woven belt is 90-95%, the high-end spandex filament content is 5-10%, the polylactic acid fiber content of the trouser body and the crotch portion accounts for 75-85% of the total usage amount of the fabric, and the polyolefin elastic fiber or the low-temperature spandex fiber accounts for 15-25% of the total usage amount of the fabric.
Preferably, the waistband is a structure woven by dope-dyed polylactic acid fibers and high-end spandex.
Preferably, the fabric of the polylactic acid fiber underpants is produced by adding polyolefin elastic fiber or low-temperature spandex which can realize complete heat setting at the temperature point of 110-135 ℃ according to the characteristic that the polylactic acid fiber is not resistant to the high temperature of more than 140 ℃, weaving the polylactic acid fiber underpants with 32GG or 36GG single-side large circles to form grey cloth, and carrying out complete dyeing and finishing technology.
Preferably, the crotch portion comprises an inner layer and an outer layer.
After structure and surface fabric more than adopting, the utility model has the advantages of as follows:
(1) the main material of the fabric adopts polylactic acid fiber from plants, and the fabric has the effects of natural bacteriostasis, high air permeability, moisture permeability, quick drying, skin friendliness and the like;
(2) the color selectivity of the fabric is wider;
(3) the fabric has excellent dimensional stability, better top breaking force and high air permeability;
(4) the bacteriostatic rates of staphylococcus aureus, escherichia coli and candida albicans of the fabric exceed the AAA level standard;
(5) the waistband is made of polylactic acid fiber and spandex, the thickness of the waistband is only 1/2 of the common waistband, the effects of bacteriostasis, ventilation, moisture conduction, skin friendliness and the like consistent with the body fabric can be achieved, and discomfort such as allergy and the like caused by direct contact of the waistband with human skin made of other materials is avoided;
(6) under specific conditions, the polylactic acid fiber part can be completely decomposed, and plays a certain role in environmental protection.
Drawings
Fig. 1 is a schematic structural diagram of polylactic acid fiber elastic underpants.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
With reference to the attached drawing 1, the polylactic acid fiber elastic underpants comprise an underpants body 1, a crotch part 2, a waistband 3 and a waistband woven belt 4, wherein the underpants body 1 and the crotch part 2 are of plain weave structures woven by polylactic acid fibers, polyolefin elastic fibers or high-end low-temperature spandex, and are woven by a high-density circular knitting machine and produced by a complete dyeing and finishing technology; the waistband woven belt 4 is positioned on the waistband 3, and the waistband woven belt 4 is of a ribbon structure formed by densely weaving polylactic acid fibers and high-end spandex filaments.
The polylactic acid fiber content of the waistband woven belt 4 accounts for 90-95%, the high-end spandex filament content accounts for 5-10%, the polylactic acid fiber content of the trouser body 1 and the crotch 2 accounts for 75-85% of the total usage amount of the fabric, and the polyolefin elastic fiber or the low-temperature spandex fiber accounts for 15-25% of the total usage amount of the fabric.
The waistband 3 is a structure woven by dope-dyed polylactic acid fiber and high-end spandex.
According to the characteristic that the polylactic acid fiber is not resistant to the high temperature of more than 140 ℃, the fabric of the polylactic acid fiber underpants is produced by adding polyolefin elastic fiber or low-temperature spandex which can realize complete heat setting when the temperature resistant point is 110-135 ℃, weaving the polylactic acid fiber underpants into grey cloth by using 32GG or 36GG single-side large circles, and carrying out complete dyeing and finishing technology.
The waistband 3 is woven by adopting dope dyed polylactic acid fiber and low-temperature spandex, the framework encryption is carried out by adopting a method of forming 1 bundle by 2 warps, proper twisting and raw material preshrinking are carried out on the polylactic acid fiber before weaving, the washing is carried out by adding decontamination auxiliary agent into hot water at 60-75 ℃ after weaving, and then the low-temperature drying and shaping at 110 ℃ are carried out.
The crotch portion 2 comprises an inner layer 201 and an outer layer 202.
During specific manufacturing, the inner layer 201 and the outer layer 202 of the crotch part 2 can be provided with a plurality of air holes, so that the air permeability is improved.
