Problems solved by technology

Wool fiber is a protein fiber, which is very different from the commonly used fibers used in the production of interlinings. Therefore, it is difficult to achieve a harmonious and unified performance between wool fabrics and commonly used fiber interlinings.

Embodiment 1

[0015] Production of wool fiber and polyester fiber mixed fiber nonwoven interlining with PA (polyester) and PES (polyamide) coating, the weight ratio of wool fiber and polyester fiber is 80:20, and the mass per unit area of ​​the base fabric is 60g / m 2 , coating size is 20g / m 2 .

[0016] The production method of this non-woven wool interlining comprises the steps:

[0017] ①In the spunlace nonwoven production line, carbonized wool fiber (length about 20 μm) and polyester fiber (fineness 1.2dtex, length 38mm) are fed into the cotton feeding machine at a weight ratio of 80:20, through opening and impurity removal , mixed, and carded into a fiber web, the speed of the production line is 45m / min,

[0018] ②Put the fiber mesh in step ① through the hydroentanglement machine for hydroentanglement reinforcement;

[0019] ③ Dry and wind the product obtained in step ② to make the required base fabric for the production of interlining, and control the weight per unit area at 60g / m...

Embodiment 2

[0023] Production of mixed fiber nonwovens of carbonized wool fiber and nylon fiber with PA coating, the weight ratio of wool fiber and nylon fiber is 40:60, and the unit area of ​​the base fabric is 30g / m 2 , the amount of sizing is 12g / m 2 .

[0024] The production method of this non-woven wool interlining comprises the steps:

[0025] ①In the hot-rolled nonwoven production line, nylon fiber (fineness 1.5dtex, length 45mm) and wool fiber (length about 18μm) are fed into the cotton feeding machine at a weight ratio of 60:40, through opening, impurity removal, Mixing, finally combing into fiber web, the production line speed is 30m / min;

[0026] ②The fiber web in step ① is thermally bonded and reinforced through a hot rolling mill;

[0027] ③ Wind the product obtained in step ② to make the required base fabric for the production of interlining, and control the grammage at 30g / m 2 ;

[0028] ④In the interlining production line, the base fabric is fed into the base fabric f...

Abstract

The present invention discloses a nonwoven wool backing cloth with base cloth and coat and its production process. The mentioned base cloth is a nonwoven base cloth produced by mixing wool fibre with one or several ordinary fibres in the mass ratio of 100:30-0:70, its weight of unit area is 14g / m2-80g / m2. The mentioned ordinary fibres include chemical fibre, synthetic fibrenatural and fibre. On the base cloth is the coat prepared by coagulating and powdering with polyester powder or polyamide powder, and its weight of unit area is 8g / m2-25g / m2. Via adding certain amount of wool to the base cloth, the performance of the lining is significantly improved, furthermore, the physical and chemical properties of the backing cloth is closer to the face fabric containing wool solving the corrugation problems of the washed dress.

Description

technical field [0001] The invention relates to the field of interlining in textile industry and its production, in particular to a production method of non-woven wool interlining. Background technique [0002] Interlining is used in modern garment processing. The function of the interlining is to ensure that the garment is crisp, draped and dimensionally stable. However, if the interlining is not properly compatible with the fabric, problems such as foaming, wrinkling or deformation will occur during wearing and washing after bonding, which will affect the quality and wearing effect of the garment. [0003] At present, the most commonly used base fabric for the production of non-woven garment interlining is made of nylon (polyamide) fiber or polyester (polyester) fiber or a mixture of these two fibers; and there are many kinds of fibers for the production of clothing fabrics. Due to the different chemical composition of various fibers, the different processing methods of ...
