Technical Field

The invention relates to a mask ear belt, in particular to an ultra-soft mask ear belt and a manufacturing method thereof.

Background

Masks are known for wearing on the face, which filter the inhaled air through the mask, allowing clean air to enter the body and preventing the respiratory tract of a person from being infected by unclean air. The mask is hung on the ears of a human body through the ear belts, so that the mask is fixed on the face of the human body to play a role in protection. Mask ear belts which circulate in markets at home and abroad are various, but all have certain defects that the tensile ratio (original length of the ear belt: maximum tensile length) of the mask ear belt is 1:2.0-2.4, and when the mask ear belt is used for a skin allergy user or a child mask ear belt, the pressure on ears is very high, so that serious allergy and discomfort can be caused. Meanwhile, most of the mask ear belts adopt polyester filament yarns with single fiber fineness more than 2D and double-layer spandex coated yarns to interweave with the circular-section ear belts, so that the mask ear belts are high in bending rigidity, weak in velvet feeling, hard in hand feeling and poor in contact comfort.

Summary of the invention

Based on the problems and deficiencies of the background art, the invention aims to provide a novel ultra-soft mask ear band and a manufacturing method thereof.

In order to achieve the purpose, the novel ear belt for the ultra-soft mask has the advantages that the stretching ratio is more than 1:2.8, the stretching ratio of a common elastic band is 1:2.0-2.4, the ear belt for the ultra-soft mask has small tension under the same stretching condition, the pressure on ears is small, and the ear belt for the ultra-soft mask has excellent pressure comfort. The mask ear belt has a rectangular cross section, the thickness is controlled to be less than 1mm, and the mask ear belt has small bending rigidity and is soft. Meanwhile, the polyester filament yarns or the polyamide filament yarns with the single fiber fineness of about 2D are interwoven with the single-layer spandex covered yarns, the bending rigidity of the interwoven polyester filament yarns with the single fiber fineness of more than 2D and the interwoven double-layer spandex covered yarns is 30% lower, the velvet feeling is strong, the hand feeling is softer and smoother, and the novel double-layer spandex covered belt is particularly suitable for skin allergy users or children mask ear belts.

In order to achieve the purpose, the manufacturing method of the ear band of the ultra-soft mask comprises the following steps:

the mask ear belt has a rectangular cross section, the thickness is controlled to be less than 1mm, and the mask ear belt has small bending rigidity and is soft.

The ear belt warp of the mask adopts 30-40D spandex to coat 60-80D/68-78f terylene or chinlon filament, adopts a single-layer spandex coating method, and has the spandex coating yarn stretch ratio of 1: 3.4-3.6.

The gauze mask ear belt weft adopts 70-80D/34-38f terylene or chinlon filament.

Weaving the mask ear belt, wherein the fabric weave of the mask ear belt adopts a plain weave, the number of warp yarns is 35-37, and the weft yarn density is 40-44 picks/2.54 cm.

After being woven, the ear belt of the mask is thermally contracted in an oven at the temperature of 70-80 ℃ for 4-4.5h, so that the internal stress is eliminated on one hand, and the tensile ratio in the using process is increased on the other hand.

After the ear belt of the mask is thermally shrunk, hot roller transfer printing or no printing can be adopted, but the ear belt of the mask must be continuously wound on the surface of a hot roller with the temperature of 170-180 ℃ for shaping for 1.5-2min so as to improve the color fastness of the ear belt of the mask and the dimensional stability and the flatness.

When the ear band of the ultra-soft mask is worn, the ear band of the ultra-soft mask has small tension, small pressure on ears, excellent pressure comfort, small bending rigidity, strong velvet feeling, softer and smoother hand feeling, excellent contact comfort and is particularly suitable for skin allergy users or ear bands of children masks.
