A rainproof and warm velvet fabric

Abstract

This invention discloses a rainproof and warm velvet fabric, which is formed by cutting and finishing an upper and lower base fabric connected by pile warps. The upper and lower base fabrics include a weft channel formed between the rainproof layer and the velvet layer base fabric. The upper base fabric is woven from upper warp and upper weft yarns, and the lower base fabric is woven from lower warp and lower weft yarns. Some of the upper and lower weft yarns use water-swellable yarns that have undergone waterproofing treatment, giving the fabric rainproof properties, while the cut pile velvet fabric provides warmth. The water-swellable yarns used expand after absorbing water, reducing airflow and thus working well with the velvet fabric for excellent warmth retention. When it doesn't rain, after the fabric dries, these water-swellable yarns return to their original shape, and the fabric can be used as normal.

Description

Technical Field

[0001] This invention relates to velvet fabrics, and more particularly to a rainproof and warm velvet fabric, belonging to the field of textile technology. Background Technology

[0002] While a wide variety of rainproof fabrics and velvet fabrics are available, fabrics combining rainproof and velvet properties are still relatively rare. Rainy days are generally cooler, so people want both rain protection and warmth, creating a market demand for rainproof and warm velvet. However, wearing rainproof and warm velvet fabric can be uncomfortable on dry days. Conversely, wearing rainproof velvet when it rains can be unpredictable. Ideally, rainproof and warm velvet fabric should function normally when not raining, but provide rain protection and warmth when it rains. How to develop such a fabric has become a key problem to solve. Summary of the Invention

[0003] The purpose of this invention is to provide a rainproof and warm velvet fabric that can be used as a normal fabric when it is not raining, and can provide rainproof and warm protection when it rains.

[0004] To solve the above-mentioned technical problems, the objective of this invention is achieved as follows:

[0005] The present invention relates to a rainproof and warm velvet fabric, which is made by cutting the pile of an upper base fabric and a lower base fabric connected by pile warp and then finishing them.

[0006] The upper base fabric includes an upper rainproof layer and an upper velvet base fabric, and the upper rainproof layer and the upper velvet base fabric have an upper first weft channel and an upper second weft channel between them;

[0007] The lower base fabric includes a lower rainproof layer and a lower velvet base fabric, and there is a lower first weft channel and a lower second weft channel between the lower rainproof layer and the lower velvet base fabric;

The upper warp yarns include upper first warp yarns, upper second warp yarns, upper third warp yarns, and upper fourth warp yarns. The upper weft yarns include upper first weft yarns to upper twenty-fourth weft yarns.

[0101] At this point, the weaving of one unit of the upper second weft channel and the lower second weft channel is completed, and the weaving cycle continues according to this unit.

[0102] Step 4: Pile cutting and finishing; the finishing process includes at least waterproofing.

[0103] Table 1 shows the yarn lift pattern during a single cycle of weaving for rainproof and warm velvet fabric.

[0104] Table 1. Yarn supply patterns during a single weaving cycle.

[0105]

[0106]

[0107] In the table, ╳ indicates that the corresponding warp yarn is moving upwards, ↑ indicates that the pile warp is raised upwards, — indicates that the pile warp is placed in the middle, and ↓ indicates that the pile warp is lowered downwards.

[0108] The result of cutting and splitting the fibers to form something like this Figure 1 The rainproof and warm velvet fabric shown comprises a rainproof layer TAWA and a velvet base fabric TBWB, with a cavity formed between the rainproof layer TAWA and the velvet base fabric TBWB as a weft channel.

[0109] Because the upper layer of this fabric has tight warp yarns, the first warp yarn T1 and the third warp yarn T3 are tight warp yarns, and these yarns that swell when exposed to water are all on the outside of the tight warp yarns. Furthermore, the first warp yarn T1, as a tight warp yarn, is located in the upper velvet layer base fabric at the first weft channel position of the upper layer, and then reaches the upper rainproof layer at the second weft channel. Similarly, the third warp yarn T3, a tight warp yarn, is located in the upper rainproof layer at the first weft channel position of the upper layer, and then reaches the upper velvet layer at the second weft channel. These yarns not only block the swollen yarns on the outside of the tight warp yarns, but also increase the surrounding angle of the pile binding, thereby increasing the pile binding strength. More importantly, at the exchange point, these two tight warp yarns lock together the upper first and second weft channels, forcing the water-swelling yarns to bulge between the upper rainproof layer and the upper velvet base fabric. This makes the upper rainproof layer and the upper velvet base fabric thicker, thus making the rainproof and warm velvet fabric even warmer in the rain. After being cut open, the upper rainproof layer becomes the rainproof layer TAWA of the rainproof and warm velvet fabric, and the upper velvet base fabric becomes the velvet base fabric TBWB of the rainproof and warm velvet fabric. The upper first and second weft channels become the first channel M and the second channel N. After rain, the velvet base fabric TBWB absorbs moisture and becomes the water-swelling rainproof layer TA'WA'.

[0110] When it doesn't rain, once the fabric dries, these yarns that expand when wet will return to their original shape, turning back into ordinary rainproof velvet fabric. Of course, the production of this fabric benefits from the yarns that expand when wet, the fabric's structure, the weaving method, and the equipment used for weaving the fabric.

Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
